■

Active Cornering Assist operation sounds and vibrations

When the Active Cornering Assist is operated, operation sounds and vibra-
tions may be generated from the brake system, but this is not a malfunction.

■

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 TRC, Trailer Sway Control and VSC systems

After turning the TRC, Trailer Sway Control and VSC systems off, the sys-
tems will be automatically re-enabled in the following situations:

●

When the power switch is turned off

●

If only the TRC system is turned off, the TRC will turn on when vehicle
speed increases
If both the TRC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases.

■

Operating conditions of Active Cornering Assist

The system operates when the following occurs:

●

TRC/VSC can operate

●

The driver is attempting to accelerate while turning

●

The system detects that the vehicle is drifting to the outer side

●

The brake pedal is released

■

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 hybrid system
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

●

The accelerator pedal is depressed

●

The parking brake is engaged

●

2 seconds at maximum elapsed after the brake pedal is released

WARNING

■

The ABS does not operate effectively when

●

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

■

TRC/VSC may not operate effectively when

Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC/VSC system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.

■

Active Cornering Assist does not operate effectively when

●

Do not overly rely on Active Cornering Assist. Active Cornering Assist may
not operate effectively when accelerating down slopes or driving on slip-
pery road surfaces.

●

When Active Cornering Assist frequently operates, Active Cornering
Assist may temporarily stop operating to ensure proper operation of the
brakes, TRC and VSC.

WARNING

■

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 TRC/ABS/VSC/Trailer Sway Control 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 TRC/VSC/Trailer Sway Control 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 TRC/VSC/Trailer Sway Control systems off unless
necessary.
Trailer Sway Control is part of the VSC system and will not operate if VSC is
turned off or experiences a malfunction.

■

Replacing tires

Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRC, Trailer Sway Control and VSC systems will not function cor-
rectly if different tires are installed on the vehicle.
Contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer for further information when replacing tires or wheels.

WARNING

■

Handling of tires and the suspension

Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

■

Trailer Sway Control precaution

The Trailer Sway Control system is not able to reduce trailer sway in all situ-
ations.
Depending on many factors such as the conditions of the vehicle, trailer,
road surface and driving environment, the Trailer Sway Control system may
not be effective. Refer to your trailer owner’s manual for information on how
to tow your trailer properly.

■

If trailer sway occurs

Observe the following precautions.
Failing to do so may cause death or serious injury.

●

Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer sway by turning the steering wheel.

●

Begin releasing the accelerator pedal immediately but very gradually to
reduce speed.
Do not increase speed. Do not apply vehicle brakes.

If you make no extreme correction with the steering or brakes, your vehicle
and trailer should stabilize. (

Hybrid Electric 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. 430)

◆

Use of Hybrid System Indicator

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



P. 166)

◆

Shift lever operation

Shift the shift lever to D when stopped at a traffic light, or driving in
heavy traffic, etc. Shift the shift lever 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:

539

4-6. Driving tips

riv

◆

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.
Fuel consumption can be improved by avoiding overuse of the
heater.

540

4-6. Driving tips

◆

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.

: Tire chains cannot be mounted on 18-inch tires or 19-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

542

4-6. Driving tips

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 lever 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 vehi-
cle 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.

●

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 any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer immediately.



17-inch tires

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

Side chain

3 mm (0.12 in.) in diameter
10 mm (0.39 in.) in width
30 mm (1.18 in.) in length

Cross chain

4 mm (0.16 in.) in diameter
14 mm (0.55 in.) in width
25 mm (0.98 in.) in length



18-inch tires or 19-inch tires

Tire chains cannot be mounted as the space between the tire and
body is too narrow.

Snow tires should be used instead.

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

■

Tire chain installation

Observe the following precautions when installing and removing chains:

●

Install and remove tire chains in a safe location.

●

Install tire chains on the front tires only. Do not install tire chains on the rear
tires.

●

Install tire chains on front tires as tightly as possible. Retighten chains after
driving 0.5 - 1.0 km (1/4 - 1/2 mile).

●

Install tire chains following the instructions provided with the tire chains.
