Disabling the TRC/VSC systems (except hybrid vehicle)
If the vehicle gets stuck in fresh snow or mud, the TRC/VSC systems
may reduce power from the engine to the wheels. You may need to
turn the system off to enable you to rock the vehicle in order to free it.
Turning off the TRC system only
To turn the TRC system off,
quickly press and release the
button.
The “TRC OFF” indicator light will
come on.
Press the button again to turn the
system back on.
Turning off both TRC and VSC systems
To turn the TRC and VSC sys-
tems off, press and hold the but-
ton for more than 3 seconds
while the vehicle is stopped.
The “TRC OFF” indicator light
and VSC OFF indicator light will
come on.
Press the button again to turn the
systems back on.

Hill-start assist control operation conditions (except hybrid vehicle)
The shift lever is in D or M.
The brake pedal is not depressed.
When the “TRC OFF” indicator light comes on even if the VSC OFF
switch has not been pressed (except hybrid vehicle)
TRC and hill-start assist control cannot be operated. Contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional.
Sounds and vibrations caused by the ABS, brake assist, TRC and VSC
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 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.
Reactivation of the TRC/VSC systems after turning off the engine
(except hybrid vehicle)
Even after the TRC/VSC systems have been turned off, turning the engine
off and then on again will automatically reactivate the TRC/VSC systems.
Reactivation of the TRC system linked to vehicle speed (except hybrid
vehicle)
When only the TRC system is turned off, the TRC system will turn on when
vehicle speed increases. However, when both TRC and VSC systems are
turned off, the systems will not turn on even 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
(except hybrid vehicle) or hybrid system (hybrid vehicle) off. The EPS sys-
tem should return to normal within 10 minutes.
If the slip indicator comes on
It may indicate a malfunction in the driving assist systems. Contact any
authorized Toyota dealer or repairer, or another duly qualified and equipped
professional.
CAUTION
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 fol-
lowing 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 roads with uneven surfaces
TRC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
Hill-start assist control does not operate effectively when
Do not overly rely on the hill-start assist control. The hill-start assist control
may not operate effectively on steep inclines and roads covered with ice.

CAUTION
When the 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 TRC/VSC systems are turned off (except hybrid vehicle)
Be especially careful and drive at a speed appropriate to the road condi-
tions. Do not turn the TRC/VSC systems off unless necessary, as these are
the systems to ensure vehicle stability and driving force by automatically
controlling braking and engine outputs.
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 and VSC systems will not function correctly if different tires
are installed on the vehicle.
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional for further information when replacing tires or
wheels.
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.

Check for and remove any excess ice or snow that may have
accumulated 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.
When driving the vehicle
Accelerate the vehicle slowly, keep a safe distance between you
and the vehicle ahead, and drive at a reduced speed suitable to
road conditions.
When parking the vehicle (in the winter time or in the cold
latitudes)
Park the vehicle and move the shift lever to P (vehicles with a
hybrid transmission or a Multidrive), E, M or R (vehicles with a
multi-mode manual transmission), and 1 or R (vehicles with a
manual transmission) without setting the parking brake. The
parking brake may freeze up, preventing it from being released.
If necessary, block the wheels to prevent inadvertent sliding or
creeping.

Selecting tire chains
Use the correct tire chain size when mounting the tire chains.
Chain size is regulated for each tire size.
Side chain
Except 175/65R14 tires: 3 mm
(0.12 in.) in diameter
175/65R14 tires: 4 mm (0.16
in.) in diameter
Cross chain
Except 175/65R14 tires: 4 mm
(0.16 in.) in diameter
175/65R14 tires: 5 mm (0.20
in.) in diameter
Regulations on the use of tire chains
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.
If wheel ornaments are used, they will be scratched by the chain band,
so remove the ornaments before putting on the chains. (P. 581)

CAUTION
Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
Use tires of the specified size.
Maintain the recommended level of air pressure.
Do not drive at speeds in excess of the speed limit or the speed limit spec-
ified for the snow tires being used.
Use snow tires on all, not just some wheels.
Do not use tires of noticeably different wear level.
Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
Do not drive in excess of the speed limit specified for the tire chains being
used, or 50 km/h (30 mph), whichever is lower.
Avoid driving on bumpy road surfaces or over potholes.
Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden to engine braking.
Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
