4-2. Driving procedures

WARNING

■

When starting the engine

Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.

■

Caution while driving

If engine failure occurs while the vehicle is moving, do not lock or open the
doors until the vehicle reaches a safe and complete stop. Otherwise, the
steering lock function will activate and this may lead to an accident, result-
ing in death or serious injury.

■

Stopping the engine in an emergency

If you want to stop the engine in an emergency while driving the vehicle,
press and hold the engine switch for more than 2 seconds, or press it briefly
3 times or more in succession. (



P. 465)

However, do not touch the engine switch while driving except in an emer-
gency. Turning the engine off while driving will not cause loss of steering or
braking control, however, power assist to the steering will be lost. This will
make it more difficult to steer smoothly, so you should pull over and stop the
vehicle as soon as it is safe to do so.

■

When parking (except for New Caledonia)

Exhaust gases include harmful carbon monoxide (CO), which is colorless
and odorless. Observe the following precautions.
Failure to do so may cause exhaust gases to enter the vehicle and may
lead to an accident caused by light-headedness, or may lead to death or a
serious health hazard.

●

If the vehicle is in a poorly ventilated area or a closed area, such as a
garage, stop the engine.

●

Do not leave the vehicle with the engine running for a long time. If such a
situation cannot be avoided, park the vehicle in an open space and ensure
that exhaust fumes do not enter the vehicle interior.

●

Do not leave the engine running in an area with snow build-up, or where it
is snowing. If snowbanks build up around the vehicle while the engine is
running, exhaust gases may collect and enter the vehicle.

NOTICE

■

To prevent battery discharge

●

Do not leave the engine switch in ACCESSORY or IGNITION ON mode
for long periods of time without the engine running.

●

If “ACCESSORY” or “IGNITION ON” is displayed on the multi-information
display while the engine is not running, the engine switch is not off. Exit the
vehicle after turning the engine switch off.

●

Do not stop the engine when the shift lever is in a position other than P. If
the engine is stopped in another shift lever position, the engine switch will
not be turned off but instead be turned to ACCESSORY mode. If the vehi-
cle is left in ACCESSORY mode, battery discharge may occur.

■

When starting the engine

●

Do not race a cold engine.

●

If the engine becomes difficult to start or stalls frequently, have your vehi-
cle checked by your Toyota dealer immediately.

■

Symptoms indicating a malfunction with the engine switch

If the engine switch seems to be operating somewhat differently than usual,
such as the switch sticking slightly, there may be a malfunction. Contact
your Toyota dealer immediately.

: To improve fuel efficiency and reduce noises, set the shift lever in the D

position for normal driving.

*

2

: Selecting shift ranges using S mode restricts the upper limit of the possible

gear ranges, controls engine braking forces, and prevents unnecessary
upshifting.

Use when high levels of response and feeling are desirable, such as
when driving in mountainous regions or when pulling a trailer.
Press the “ECT PWR” button to
select power mode.

The “ECT PWR” indicator comes

When the shift lever is in the S position, the shift lever can be oper-
ated as follows:

Upshifting
Downshifting

The initial shift range in S mode is set automatically to 5 or 4 accord-
ing to vehicle speed. However, the initial shift range may be set to 3 if
the AI-SHIFT has operated while the shift lever was in the D position.
(



P. 212)

■

Shift ranges and their functions

●

You can choose from 6 levels engine braking force.

●

A lower shift range will provide greater engine braking force than
a higher shift range, and the engine speed will also increase.

■

AI-SHIFT

AI-SHIFT automatically selects the suitable gear according to the driver per-
formance and driving conditions.
AI-SHIFT automatically operates when the shift lever is in the D position.
(Shifting the shift lever to the S position cancels the function.)

■

When driving with cruise control activated (if equipped)

Even when performing the following actions with the intent of enabling engine
braking, engine braking will not activate while driving in S mode and down-
shifting to 5 or 4 because cruise control will not be canceled. (

Shift lock system

The shift lock system is a system to prevent accidental operation of the shift
lever in starting.
The shift lever can be shifted from P only when the engine switch is in the
“ON” position (vehicles without a smart key system) or IGNITION ON mode
(vehicles with a smart key system) and the brake pedal is being depressed.

■

If the shift lever cannot be shift from P

First, check whether the brake pedal is being depressed.
If the shift lever cannot be shifted with your foot on the brake pedal, there may
be a problem with the shift lock system. Have the vehicle inspected by your
Toyota dealer immediately.
The following steps may be used as an emergency measure to ensure that
the shift lever can be shifted.
Releasing the shift lock:

Set the parking brake.
Vehicles without a smart key system: Turn the engine switch to the
“LOCK” position.
Vehicles with a smart key system: Turn the engine switch off.
Depress the brake pedal.
Pry the cover up with a flathead
screwdriver or equivalent tool.

To prevent damage to the cover,
cover the tip of the screwdriver with
a rag.

The shift lever can be shifted while
the button is pressed.

■

If the “S” indicator does not come on even after shifting the shift lever to S

This may indicate a malfunction in the automatic transmission system. Have
the vehicle inspected by your Toyota dealer, immediately.

■

Downshifting restrictions warning buzzer (S mode)

To help ensure safety and driving performance, downshifting operation may
sometimes be restricted. In some circumstances, downshifting may not be
possible even when the shift lever is operated. (A buzzer will sound twice.)

■

Transmission protection function

If the tires spin continually when the vehicle becomes stuck in mud, dirt or
snow, or if the accelerator pedal is depressed and released repeatedly while
driving, the automatic transmission temperature may become too high and
the automatic transmission may be damaged.
To avoid damaging the automatic transmission, the system may temporarily
lock the gear.
If the automatic transmission temperature falls, the gear locking is canceled
and the automatic transmission is returned to the normal operation.

WARNING

■

When driving on slippery road surfaces

Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.

■

To prevent an accident when releasing the shift lock

Before pressing the shift lock override button, make sure to set the parking
brake and depress the brake pedal.
If the accelerator pedal is accidentally depressed instead of the brake pedal
when the shift lock override button is pressed and the shift lever is shifted
out of P, the vehicle may suddenly start, possibly leading to an accident
resulting in death or serious injury.

Daytime running light system

●

The daytime running lights illuminate using the same lights as the front turn
signal/parking lights, and illuminate brighter than the front turn signal/park-
ing lights.

●

To make your vehicle more visible to other drivers during daytime driving,
the daytime running lights turn on automatically when all of the following
conditions are met. (The daytime running lights are not designed for use at
night.)
• The engine is running
• The parking brake is released
• The headlights switch is in “AUTO”* (type A and C) or the “DRL” (type B)

position

*

: When the surroundings are bright

The daytime running lights remain on after they illuminate, even if the parking
brake is set again.

●

Compared to turning on the headlights, the daytime running light system
offers greater durability and consumes less electricity, so it can help improve
fuel economy.

WARNING

■

When refueling the vehicle

Observe the following precautions while refueling the vehicle.
Failure to do so may result in death or serious injury.

●

After exiting the vehicle and before opening the fuel door, touch an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling, because sparks resulting from
static electricity can cause fuel vapors to ignite while refueling.

●

Always hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out the filler neck and cause injury.

●

Do not allow anyone that has not discharged static electricity from their
body to come close to an open fuel tank.

●

Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.

●

Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.

●

Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition
hazard.

■

When refueling

Observe the following precautions to prevent fuel overflowing from the fuel
tank:

●

Securely insert the fuel nozzle into the fuel filler neck.

●

Stop filling the tank after the fuel nozzle automatically clicks off.

●

Do not top off the fuel tank.

NOTICE

■

Refueling

Do not spill fuel during refueling.
Doing so may damage the vehicle, such as causing the emission control
system to operate abnormally, or damaging fuel system components or the
vehicle’s painted surface.

The Toyota Safety Sense P consists of the following drive assist
systems and contributes to a safe and comfortable driving expe-
rience:

WARNING

■

Toyota Safety Sense P

The Toyota Safety Sense P is designed to operate under the assumption
that the driver will drive safely, and is designed to help reduce the impact to
the occupants and the vehicle in the case of a collision or assist the driver in
normal driving conditions.
As there is a limit to the degree of recognition accuracy and control perfor-
mance that this system can provide, do not overly rely on this system. The
driver is always responsible for paying attention to the vehicle’s surround-
ings and driving safely.

The pre-collision system is equipped with a sophisticated computer
that will record certain data, such as:

• Accelerator status
• Brake status
• Vehicle speed
• Operation status of the pre-collision system functions
• Information (such as the distance and relative speed between your

vehicle and the vehicle ahead or other objects)

• Images from the camera sensor (available only when the pre-colli-

sion braking function or the pre-collision brake assist function was
operating)

The pre-collision system does not record conversations, sounds or
images of the inside of the vehicle.

●

Data usage
Toyota may use the data recorded in this computer to diagnose
malfunctions, conduct research and development, and improve
quality.
Toyota will not disclose the recorded data to a third party except:

• With the consent of the vehicle owner or with the consent of the

lessee if the vehicle is leased

• In response to an official request by the police, a court of law or a

government agency

• For use by Toyota in a lawsuit
• For research purposes where the data is not tied to a specific

vehicle or vehicle owner

●

Recorded images can be erased using a specialized device.
The image recording function can be disabled. However, if the func-
tion is disabled, data from when the pre-collision system operates
will not be available.

PCS (Pre-Collision System)





: If equipped

The pre-collision system uses a radar sensor and camera sen-
sor to detect vehicles and pedestrians in front of your vehicle.
When the system determines that the possibility of a frontal col-
lision with a vehicle or pedestrian is high, a warning operates to
urge the driver to take evasive action and the potential brake
pressure is increased to help the driver avoid the collision. If the
system determines that the possibility of a frontal collision with
a vehicle or pedestrian is extremely high, the brakes are auto-
matically applied to help avoid the collision or help reduce the
impact of the collision.

The pre-collision system can be disabled/enabled and the warning
timing can be changed. (



P. 247)

244

4-5. Using the driving support systems

◆

Pre-collision warning

When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.

◆

Pre-collision brake assist

When the system determines that the possibility of a frontal colli-
sion is high, the system applies greater braking force in relation to
how strongly the brake pedal is depressed.

◆

Pre-collision braking

When the system determines that the possibility of a frontal colli-
sion is high, the system warns the driver. If the system determines
that the possibility of a frontal collision is extremely high, the brakes
are automatically applied to help avoid the collision or reduce the
collision speed.

WARNING

■

Limitations of the pre-collision system

●

The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-collision system instead of normal braking operations
under any circumstances. This system will not prevent collisions or lessen
collision damage or injury in every situation. Do not overly rely on this sys-
tem. Failure to do so may lead to an accident, resulting in death or serious
injury.

●

Although this system is designed to help avoid a collision or help reduce
the impact of the collision, its effectiveness may change according to vari-
ous conditions, therefore the system may not always be able to achieve
the same level of performance.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• Conditions under which the system may operate even if there is no pos-

sibility of a collision:



P. 251

• Conditions under which the system may not operate properly:



P. 253

●

Do not attempt to test the operation of the pre-collision system yourself.
Depending on the objects used for testing (dummies, cardboard objects
imitating detectable objects, etc.), the system may not operate properly,
possibly leading to an accident.

■

Pre-collision braking

●

When the pre-collision braking function is operating, a large amount of
braking force will be applied.

●

If the vehicle is stopped by the operation of the pre-collision braking func-
tion, the pre-collision braking function operation will be canceled after
approximately 2 seconds. Depress the brake pedal as necessary.

●

The pre-collision braking function may not operate if certain operations are
performed by the driver. If the accelerator pedal is being depressed
strongly or the steering wheel is being turned, the system may determine
that the driver is taking evasive action and possibly prevent the pre-colli-
sion braking function from operating.

●

In some situations, while the pre-collision braking function is operating,
operation of the function may be canceled if the accelerator pedal is
depressed strongly or the steering wheel is turned and the system deter-
mines that the driver is taking evasive action.

●

If the brake pedal is being depressed, the system may determine that the
driver is taking evasive action and possibly delay the operation timing of
the pre-collision braking function.

246

4-5. Using the driving support systems

WARNING

■

When to disable the pre-collision system

In the following situations, disable the system, as it may not operate prop-
erly, possibly leading to an accident resulting in death or serious injury:

●

When the vehicle is being towed

●

When your vehicle is towing another vehicle

●

When transporting the vehicle via truck, boat, train or similar means of
transportation

●

When the vehicle is raised on a lift with the engine running and the tires
are allowed to rotate freely

●

When inspecting the vehicle using a drum tester such as a chassis dyna-
mometer or speedometer tester, or when using an on vehicle wheel bal-
ancer

●

When a strong impact is applied to the front bumper or front grille, due to
an accident or other reasons

●

If the vehicle cannot be driven in a stable manner, such as when the vehi-
cle has been in an accident or is malfunctioning

●

When the vehicle is driven in a sporty manner or off-road

●

When the tires are not properly inflated

●

• Vehicle speed is between approximately 7 and 110 mph (10 and 180 km/h).

(For detecting a pedestrian, vehicle speed is between approximately 7 and
50 mph [10 and 80 km/h].)

• The relative speed between your vehicle and the vehicle or pedestrian

ahead is approximately 7 mph (10 km/h) or more.

●

Pre-collision brake assist:
• Vehicle speed is between approximately 20 and 110 mph (30 and 180 km/h).

(For detecting a pedestrian, vehicle speed is between approximately 20 and
50 mph [30 and 80 km/h].)

• The relative speed between your vehicle and the vehicle or pedestrian

ahead is approximately 20 mph (30 km/h) or more.

●

Pre-collision braking:
• Vehicle speed is between approximately 7 and 110 mph (10 and 180 km/h).

(For detecting a pedestrian, vehicle speed is between approximately 7 and

WARNING

■

Before using LDA system

Do not rely solely upon the LDA system. The LDA system does not auto-
matically drive the vehicle or reduce the amount of attention that must be
paid to the area in front of the vehicle. The driver must always assume full
responsibility for driving safely by always paying careful attention to the sur-
rounding conditions and operating the steering wheel to correct the path of
the vehicle. Also, the driver must take adequate breaks when fatigued, such
as from driving for a long period of time.
Failure to perform appropriate driving operations and pay careful attention
may lead to an accident, resulting in death or serious injury.

■

To avoid operating LDA system by mistake

When not using the LDA system, use the LDA switch to turn the system off.

■

Situations unsuitable for LDA system

Do not use the LDA system in the following situations.
The system may not operate properly and lead to an accident, resulting in
death or serious injury.

could not be recognized.

When the system determines that the
vehicle is swaying while the vehicle sway
warning function is operating, a buzzer
sounds and a warning message urging
the driver to rest and the symbol shown in
the illustration are simultaneously dis-
played on the multi-information display.

Dynamic radar cruise control



In vehicle-to-vehicle distance control mode, the vehicle automatically
accelerates and decelerates to match the speed changes of the pre-
ceding vehicle even if the accelerator pedal is not depressed. In con-
stant speed control mode, the vehicle runs at a fixed speed.
Use the dynamic radar cruise control on freeways and highways.

WARNING

■

Before using dynamic radar cruise control

●

Driving safely is the sole responsibility of the driver. Do not rely solely on
the system, and drive safely by always paying careful attention to your sur-
roundings.

●

The dynamic radar cruise control provides driving assistance to reduce the
driver’s burden. However, there are limitations to the assistance provided.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• When the sensor may not be correctly detecting the vehicle ahead:



P. 276

• Conditions under which the vehicle-to-vehicle distance control mode

may not function correctly:



P. 278

●

Set the speed appropriately depending on the speed limit, traffic flow, road
conditions, weather conditions, etc. The driver is responsible for checking
the set speed.

●

Even when the system is functioning normally, the condition of the preced-
ing vehicle as detected by the system may differ from the condition
observed by the driver. Therefore, the driver must always remain alert,
assess the danger of each situation and drive safely. Relying on this sys-
tem or assuming the system ensures safety while driving can lead to an
accident, resulting in death or serious injury.

●

Switch the dynamic radar cruise control off using the “ON-OFF” button
when not in use.

■

Cautions regarding the driving assist systems

Observe the following precautions, as there are limitations to the assistance
provided by the system.
Failure to do so may cause an accident resulting in death or serious injury.

●

Assisting the driver to measure following distance
The dynamic radar cruise control is only intended to help the driver in
determining the following distance between the driver’s own vehicle and a
designated vehicle traveling ahead. It is not a mechanism that allows care-
less or inattentive driving, and it is not a system that can assist the driver in
low-visibility conditions. It is still necessary for driver to pay close attention
to the vehicle’s surroundings.

●

Assisting the driver to judge proper following distance
The dynamic radar cruise control determines whether the following dis-
tance between the driver’s own vehicle and a designated vehicle traveling
ahead is within a set range. It is not capable of making any other type of
judgement. Therefore, it is absolutely necessary for the driver to remain
vigilant and to determine whether or not there is a possibility of danger in
any given situation.

WARNING

●

Assisting the driver to operate the vehicle
The dynamic radar cruise control has limited capability to prevent or avoid
a collision with a vehicle traveling ahead. Therefore, if there is ever any
danger, the driver must take immediate and direct control of the vehicle
and act appropriately in order to ensure the safety of all involved.

■

Situations unsuitable for dynamic radar cruise control

Do not use dynamic radar cruise control in any of the following situations.
Doing so may result in inappropriate speed control and could cause an acci-
dent resulting in death or serious injury.

●

Roads where there are pedestrians, cyclists, etc.

●

In heavy traffic

●

On roads with sharp bends

●

On winding roads

●

On slippery roads, such as those covered with rain, ice or snow

●

On steep downhills, or where there are sudden changes between sharp up
and down gradients
Vehicle speed may exceed the set speed when driving down a steep hill.

●

At entrances to freeways and highways

●

When weather conditions are bad enough that they may prevent the sen-
sors from detecting correctly (fog, snow, sandstorm, heavy rain, etc.)

●

When there is rain, snow, etc., on the front surface of the radar sensor or
camera sensor

●

In traffic conditions that require frequent repeated acceleration and decel-
eration

●

When your vehicle is towing a trailer or during emergency towing

●

When an approach warning buzzer is heard often

4-5. Using the driving support systems

This mode employs a radar sensor to detect the presence of vehicles
up to approximately 328 ft. (100 m) ahead, determines the current
vehicle-to-vehicle following distance, and operates to maintain a suit-
able following distance from the vehicle ahead.

Note that vehicle-to-vehicle distance will close in when traveling on down-
hill slopes.

Example of constant speed cruising
When there are no vehicles ahead

The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle distance can also be set by operating the vehicle-to-vehicle dis-
tance switch.

Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears

When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.

Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed

The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.
