■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 excessi ve steering input or stop the vehicle
and turn the engine off. The EPS system should return to normal within 10
minutes.
■ If the slip indicator comes on
It may indicate a malfunction in the systems. Contact your Toyota dealer.
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
■ TRAC may not operat e effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.

WARNING
■When the VSC is activated
The slip indicator flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■ When the TRAC/VSC syst ems 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.
■
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, TRAC and VSC systems will not function correctly if different
tires are installed on the vehicle.
Contact your Toyota dealer for furt her 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 malfunc-
tion.

Winter driving tips
●Use fluids that are appropriate to the prevailing outside tempera-
tures. • Engine oil
• Engine coolant
• Washer fluid
● Have a service technician ins pect 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 their wear
level is not noticeably different with each other. Also make sure that
chains match the size of the tires.
Perform the following accordin g 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.
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.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Al ways drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.

1984-7. Driving tips
●Park the vehicle and move the shift lever to P (automatic transmis-
sion) or 1 or R (manual transmis sion) without setting the parking
brake. The parking brake may freeze up, preventing it from being
released. If the vehicl e 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, leading to an accident.
● On vehicles with an automatic trans mission, 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.
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 mm) in diameter
Cross chain
0.16 in. (4 mm) in diameter
Regulations regarding the use of tire chains vary depending on loca-
tion and type of road. Al ways 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 1/4 ⎯ 1/2 mile (0.5 ⎯ 1.0 km).
● Install tire chains following the instructions provided with the tire ch\
ains.
● If wheel ornaments are used, they will be scratched by the chain band, so
remove the ornaments before putting on the chains. ( →P. 316)
WARNING
■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 in excess of 75 mph (120 km/h), regardless of the type of
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 30 mph (50 km/h), 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 engine braking.
● Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
● Do not use LDA (Lane Departure Alert) (if equipped).

NOTICE
■Repairing or replacing snow tires (vehicles with a tire pressure warn-
ing system)
Request repairs or replacement of snow tires from Toyota dealers or legiti-
mate tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion of the tire pressure warning valves and transmitters.
■ Fitting tire chains (vehicles with a tire pressure warning system)
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.
