the vehicle can be quickly stopped).

●

In order to operate the function correctly, drive slowly (at a speed at which
the vehicle can be quickly stopped). Come to a full stop so that the center of
the parking space is nearly perpendicular to the vehicle, and then operate
the S-APGS switch.

●

The function cannot be used when the vehicle speed is approximately
19 mph (30 km/h) or higher.

●

The front side sensors and rear side sensors are used to detect parked
vehicles and determine the parking spot. Therefore, when detection is not
possible (



P. 419), guidance is not issued.

●

If there are no parked vehicles, the parking spot cannot be determined.
Therefore, the back-in parking assist mode cannot be operated.

●

If unable to detect the environment surrounding the parking space, the
back-in parking assist mode may not be able to operate.

Tips for using the back-in parking assist mode

●

Depending on the condition of the park-
ing space, if there is not enough space
in front of the vehicle required to perform
the parking operation, the target parking
spot may not be reachable.

Intended parking spot
Wall

●

Leave a gap of approximately 3.3 ft.
(1 m) from any parked vehicles and
approach the target parking spot. If the
gap between your vehicle and any
parked vehicles is too large, the front
side sensors and rear side sensors may
not be able to detect the parked vehi-
cles.

●

Stop so that the center of the target
parking spot is perpendicular to the vehi-
cle. Furthermore, only push the S-APGS
switch when the vehicle is at a complete
stop.

NOTICE

●

If the road surface has any dips or inclines, the target parking spot cannot
be correctly set. Therefore, the vehicle may be parked at an angle or may
deviate from the parking spot. In these cases, do not use the back-in park-
ing assist mode.

●

When parking in a narrow space, the vehicle will come close to adjacent
vehicles. If it seems the vehicle may make contact, stop the vehicle by
depressing the brake pedal.

●

It may not be possible to detect objects that are low to the ground. Directly
confirm the safety of your surroundings and, if it seems the vehicle may
make contact with an obstacle, stop the vehicle by depressing the brake
pedal.

●

Depending on the surrounding environment, such as other parked vehi-
cles, the vehicle may be parked at an angle or may deviate from the park-
ing spot. Manually adjust vehicle alignment as necessary.

WARNING

●

Do not use the system in the following situations, as the system may be
unable to correctly assist you in reaching the target parking spot and may
lead to an unexpected accident.
• In an area that is not a parking lot
• A parking lot that is not paved and has no parking space lines, such as

a sand or gravel parking lot

• A parking lot that has a slope or undulations in the road
• A frozen, snow-covered or slippery road
• The asphalt is melting due to hot weather
• There is an obstacle between the vehicle and the target parking spot
• Using tire chains or compact spare tire (if equipped)

●

Do not use tire other than that provided by the manufacturer. The system
may not operate properly. When replacing tires, contact your Toyota
dealer.

●

The system may not be able position the vehicle in the set location in the
following situations.
• The tires are extremely worn or the tire pressure is low
• The vehicle is carrying very heavy load
• The vehicle is tilted due to having luggage, etc. located on one side of

the vehicle

• There are road heaters installed in the parking lot to prevent the road

surface from freezing.

In any other situations when the set position and vehicle position greatly
differ, have the vehicle inspected by your Toyota dealer.

●

Make sure to observe the following precautions regarding the exit parallel
parking assist mode.
Exit parallel parking assist mode is a function used when departing from a
parallel parking spot. However, this function may not be usable if obsta-
cles or people are detected in front of the vehicle. Only use this function

P. 368)

• Even after the scan of the side areas is completed, obstacles such as

other vehicles, people or animals that approach from the sides cannot
be detected.

• The sensor is frozen (if it thaws, the system returns to normal).

A warning message may display at particularly low temperatures due to
the sensor freezing and it may not detect parked vehicles.

• The sensor is blocked by someone’s hand.
• The vehicle is tilted a large amount.
• The temperature is extremely hot or cold.
• The vehicle is driven on undulating roads, slopes, gravel roads, in areas

with tall grass, etc.

• An ultrasonic wave source is nearby, such as the horn or sensors of

another vehicle, a motorcycle engine or the air brake of a large vehicle.

• Heavy rain or a water strikes the vehicle.
• The angle of the sensor may be deviated when assist control starts

even if there is a parked vehicle in the target parking spot. Have the
vehicle inspected at your Toyota dealer.

• Do not install any accessories within the sensor detection range.

Hybrid vehicle driving tips

◆

Using Eco drive mode

When using Eco drive mode, the torque corresponding to the accel-
erator pedal depression amount can be generated more smoothly
than it is in normal conditions. In addition, the operation of the air
conditioning system (heating/cooling) will be minimized, improving
the fuel economy. (



P. 347)

◆

Use of Hybrid System Indicator

The Eco-friendly driving is possible by keeping the Hybrid System
Indicator within Eco area. (



P. 129)

◆

Shift position operation

Shift the shift position to D when stopped at a traffic light, or driving
in heavy traffic etc. Shift the shift position to P when parking. When
using the N, there is no positive effect on fuel consumption. In the
N, the gasoline engine operates but electricity cannot be gener-
ated. Also, when using the air conditioning system, etc., the hybrid
battery (traction battery) power is consumed.

◆

Accelerator pedal/brake pedal operation

●

Drive your vehicle smoothly. Avoid abrupt acceleration and
deceleration. Gradual acceleration and deceleration will make
more effective use of the electric motor (traction motor) without
having to use gasoline engine power.

●

Avoid repeated acceleration. Repeated acceleration consumes
hybrid battery (traction battery) power, resulting in poor fuel con-
sumption. Battery power can be restored by driving with the
accelerator pedal slightly released.

For economical and ecological driving, pay attention to the fol-
lowing points:

428

PRIUS_OM_OM47E09U_(U)

4-6. Driving tips

◆

When braking

Make sure to operate the brakes gently and in a timely manner. A
greater amount of electrical energy can be regenerated when slow-
ing down.

◆

Delays

Repeated acceleration and deceleration, as well as long waits at
traffic lights, will lead to bad fuel economy. Check traffic reports
before leaving and avoid delays as much as possible. When driving
in a traffic jam, gently release the brake pedal to allow the vehicle to
move forward slightly while avoiding overuse of the accelerator
pedal. Doing so can help control excessive gasoline consumption.

◆

Highway driving

Control and maintain the vehicle at a constant speed. Before stop-
ping at a toll booth or similar, allow plenty of time to release the
accelerator and gently apply the brakes. A greater amount of elec-
trical energy can be regenerated when slowing down.

◆

Air conditioning

Use the air conditioning only when necessary. Doing so can help
reduce excessive gasoline consumption.
In summer: When the ambient temperature is high, use the recircu-
lated air mode. Doing so will help to reduce the burden on the air
conditioning system and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut out
until it and the interior of the vehicle are warm, it will consume fuel.
Also, fuel consumption can be improved by avoiding overuse of the
heater.

◆

Checking tire inflation pressure

Make sure to check the tire inflation pressure frequently. Improper
tire inflation pressure can cause poor fuel economy.
Also, as snow tires can cause large amounts of friction, their use on
dry roads can lead to poor fuel economy. Use tires that are appro-
priate for the season.

◆

Luggage

Carrying heavy luggage will lead to poor fuel economy. Avoid carry-
ing unnecessary luggage. Installing a large roof rack will also cause
poor fuel economy.

◆

Warming up before driving

Since the gasoline engine starts up and cuts out automatically
when cold, warming up the engine is unnecessary. Moreover, fre-
quently driving short distances will cause the engine to repeatedly
warm up, which can lead to excess fuel consumption.

Winter driving tips

●

Use fluids that are appropriate to the prevailing outside tempera-
tures.

• Engine oil
• Engine/power control unit coolant
• Washer fluid

●

Have a service technician inspect the condition of the 12-volt bat-
tery.

●

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.

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.

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 shift the shift position to P and block the wheel
under the vehicle 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 vehicle
to move unexpectedly, possibly leading to an accident.

Use the correct tire chain size when mounting the tire chains. Chain
size is regulated for each tire size.
Side chain

0.12 in. (3.0 mm)
1.18 in. (30.0 mm)
0.39 in. (10.0 mm)

Cross chain

0.16 in. (4.0 mm)
0.98 in. (25.0 mm)
0.55 in. (14.0 mm)

Regulations regarding the use of tire chains vary depending on loca-
tion and type of road. Always check local regulations before installing
chains.
