● When the ground behind the vehicle slopes up sharply
The distance guide lines will
appear to be closer to the
vehicle than the actual dis-
tance. Because of this,
objects will appear to be far-
ther away than they actually
are. In the same way, there
will be a margin of error
between the guide lines and
the actual distance/course on
the road.
● When the ground behind the vehicle slopes down sharply
The distance guide lines will
appear to be farther from the
vehicle than the actual dis-
tance. Because of this,
objects will appear to be
closer than they actually are.
In the same way, there will be
a margin of error between

● When any part of the vehicle sags
When any part of the vehicle
sags due to the number of
passengers or the distribu-
tion of the load, there is a
margin of error between the
fixed guide lines on the
screen and the actual dis-
tance/course on the road.
■
When approaching three-dimensional objects
The distance guide lines are displayed according to flat surfaced
objects (such as the road). It is not possible to determine the posi-
tion of three-dimensional objects (such as vehicles) using the vehi-
cle width guide lines and distance guide lines. When approaching a
three-dimensional object that extends outward (such as the flatbed
of a truck), be careful of the following.
● Vehicle width guide lines
Visually check the surround-
ings and the area behind the
vehicle. In the case shown in
the illustration, the truck
appears to be outside of the
vehicle width guide lines and
the vehicle does not look as if
it hits the truck. However, the
rear body of the truck may
actually cross over the vehi-
cle width guide lines. In real-
ity if you back up as guided
by the vehicle width guide
lines, the vehicle may hit the
truck.

WARNING
■
When using the rear view monitor system
The rear view monitor system is a supplemental device intended to assist
the driver when backing up. When backing up, be sure to check visually
behind and all around the vehicle before proceeding.
Observe the following precautions to avoid an accident that could result in
death or serious injuries.
●
Never depend on the rear view monitor system entirely when backing up.
The image and the position of the guide lines displayed on the screen may
differ from the actual state.
Use caution, just as you would when backing up any vehicle.
●
Be sure to back up slowly, depressing the brake pedal to control vehicle
speed.
●
The instructions given are only guide lines.
When and how much to turn the steering wheel will vary according to traf-
fic conditions, road surface conditions, vehicle condition, etc. when park-
ing. It is necessary to be fully aware of this before using the rear view
monitor system.
●
When parking, be sure to check that the parking space will accommodate
your vehicle before maneuvering into it.
●
Do not use the rear view monitor system in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or the compact spare tire
• When the back door is not closed completely
• On roads that are not flat or straight, such as curves or slopes
●
In low temperatures, the screen may darken or the image may become
faint. The image could distort when the vehicle is moving, or you may
become unable to see the image on the screen. Be sure to check visually
behind and all around the vehicle before proceeding.
●
If the tire sizes are changed, the position of the fixed guide lines displayed
on the screen may change.
●
The camera uses a special lens. The distances between objects and
pedestrians that appear in the image displayed on the screen will differ
from the actual distances. (

■
How to use the camera
●
The rear view monitor system may not operate properly in the following
cases.
• If the back of the vehicle is hit, the position and mounting angle of the
camera may change.
• As the camera has a water proof construction, do not detach, disassem-
ble or modify it. This may cause incorrect operation.
• When cleaning the camera lens, flush the camera with a large quantity
of water and wipe it with a soft and wet cloth. Strongly rubbing the cam-
era lens may cause the camera lens to be scratched and unable to
transmit a clear image.
• Do not allow organic solvent, car wax, window cleaner or a glass coat-
ing to adhere to the camera. If this happens, wipe it off as soon as pos-
sible.
• If the temperature changes rapidly, such as when hot water is poured
on the vehicle in cold weather, the system may not operate normally.
• When washing the vehicle, do not apply intensive bursts of water to the
camera or camera area. Doing so may result in the camera malfunc-
tioning.
●
Do not expose the camera to strong impact as this could cause a malfunc-
tion. If this happens, have the vehicle inspected by your Toyota dealer as
soon as possible.

Driving assist systems
◆
ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly,
or if the brakes are applied while driving on a slippery road surface
◆
Brake assist
Generates an increased level of braking force after the brake pedal
is depressed when the system detects a panic stop situation
◆
VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
◆
Enhanced VSC (Enhanced Vehicle Stability Control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery
road surfaces by controlling steering performance
◆
TRAC
(Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
◆
Hill-start assist control
Helps to reduce the backward movement of the vehicle when start-
ing on an uphill
◆
EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel.
To keep driving safety and performance, the following systems
operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavily when operating the vehi-
cle.
280

Sounds and vibrations caused by the ABS, brake assist, VSC, TRAC and
hill-start assist control systems
●
A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, when the engine is started or just after the vehicle
begins to move. This sound does not indicate that a malfunction has
occurred in any of these systems.
●
Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard also after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.

■
EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■
Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
●
Vehicles without a smart key system: When the engine switch is turned to
the “LOCK” position
Vehicles with a smart key system: When the engine switch is turned off
●
If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases.
■
Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur, refrain
from excessive steering input or stop the vehicle and turn the engine off. The
EPS system should return to normal within 10 minutes.
■
Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assist control will
operate:
●
The shift lever is in a position other than P or N (when starting off forward/
backward on an upward incline).
●
The vehicle is stopped.
●
The accelerator pedal is not depressed.
●
The parking brake is not engaged.
■
Automatic system cancelation of hill-start assist control
The hill-start assist control will turn off in any of the following situations:
●
The shift lever is shifted to P or N.
●
The accelerator pedal is depressed.
●
The parking brake is engaged.
●
2 seconds at maximum elapsed after the brake pedal is released.

●
The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
●
The vehicle hydroplanes while driving at high speed on wet or slick roads.
■
Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the
following situations:
●
When driving on dirt, gravel or snow-covered roads
●
When driving with tire chains
●
When driving over bumps in the road
●
When driving over roads with potholes or uneven surfaces
■
TRAC/VSC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC/VSC system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.
■
Hill- start assist control does not operate effectively when
●
Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on steep inclines and roads covered with ice.
●
Unlike the parking brake, hill-start assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.
■
When the TRAC/VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■
When the TRAC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRAC/VSC systems off unless necessary.

Winter driving tips
● Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the condition of the battery.
● Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the front tires
*
.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
*
: Tire chains cannot be mounted on 18 inch tires.
Perform the following according to the driving conditions:
● Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.
● To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
● Check for and remove any excess ice or snow that may have accu-
mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.
● Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.
Preparation for winter
Before driving the vehicle
286
Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to road con-
ditions.
● Park the vehicle and move the shift lever to P without setting the
parking brake. The parking brake may freeze up, preventing it from
being released. If the vehicle is parked without setting the parking
brake, make sure to block the wheels.
Failure to do so may be dangerous because it may cause the vehi-
cle to move unexpectedly, possibly leading to an accident.
● If the vehicle is parked without setting the parking brake, confirm
that the shift lever cannot be moved out of P
*.
*
: The shift lever will be locked if it is attempted to be shifted from P to any
other position without depressing the brake pedal. If the shift lever can be
shifted from P, there may be a problem with the shift lock system. Have the
vehicle inspected by your Toyota dealer immediately.
