Reduced effectiven ess of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steer ing 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 moved to P or N.
● The accelerator pedal is depressed.
● The parking brake is engaged.
● Approximately 2 seconds elapse 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

If the “DAC” switch is turned off during operation of the downhill assist
control system
The downhill assist control system gradually ceases operation. The downhill
assist control system indicator will flash during the canceling operation, and
then go off when the system is fully off.
■ Downhill assist control system operation sound
●A sound may be heard from the engine compartment during operation of the
downhill assist control system. This sound does not indicate a malfunction.
● If the accelerator or brake pedal is depressed during operation of the down-
hill assist control system, a sound caused by the release of system opera-
tion may be heard, or you may feel the brake pedal push-back. This does
not indicate a malfunction.
■ When the downhill assist control system operates continuously
The brake actuator may overheat. In that case, the downhill assist control
system will stop operating, a buzzer will sound and the downhill assist control
system indicator will start flashing. Re frain from using the system until the
downhill assist control system indicator stays on. (There is no problem with
continuing to drive normally.)
■ If the slip indicator comes on
It may indicate a malfunction in the system. Contact your Toyota dealer.
WARNING
■Conditions which may affect the downhill assist control system opera-
tion
●Do not rely too heavily on the downhill assist control system. On extremely
steep inclines, icy surfaces or muddy roads, the vehicle may slip and the
system may not be able to maintain the constant low vehicle speed of
about 3 mph (5 km/h), leading to an accident causing death or serious
injury.
● Do not shift the shift lever to R while driving forward, or to D while driving
backward. Doing so may cause the wheels to lock up, leading to an acci-
dent causing death or serious injury. In addition, excessive stress will be
applied to the automatic transmission, possibly resulting in damage.

■ Conditions under which the Rear Cross Traffic Alert function may not
function correctly
The Rear Cross Traffic Alert function may not detect vehicles correctly in the
following conditions:
●When ice or mud etc. is attached to the rear bumper
● During bad weather such as heavy rain, fog, snow etc.
● When multiple vehicles approach continuously
● Shallow angle parking
● When a vehicle is approaching at high speed
● When parking on a steep incline, such as hills, a dip in the road etc.

4-6. 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.
Winter driving tips
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.

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 size specified.
● 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.
■ 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.
● Vehicles with LDA (Lane Departure Alert) system: Do not use LDA (Lane
Departure Alert) system.
NOTICE
■Repairing or replacing snow tires
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
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.

NOTICE
■To prevent water damage
Take all necessary safety measures to ensure that water damage to the
engine or other components does not occur.
●Water entering the engine air intake will cause severe engine damage.
● Water entering the automatic transmission will cause deterioration in shift
quality, locking up of your transmission accompanied by vibration, and ulti-
mately damage.
● Water can wash the grease from wheel bearings, causing rusting and pre-
mature failure, and may also enter the differentials, transmission and
transfer case, reducing the gear oil’s lubricating qualities.
■ When you drive through water
If driving through water, such as when crossing shallow streams, first check
the depth of the water and the bottom of the riverbed for firmness. Drive
slowly and avoid deep water.
■ Inspection after off-road driving
●Sand and mud that has accumulated in brake drums and around brake
discs may affect braking efficiency and may damage brake system compo-
nents.
● Always perform a maintenance inspection after each day of off-road driv-
ing that has taken you through rough terrain, sand, mud, or water. For
scheduled maintenance information, refer to the “Scheduled Maintenance
Guide” or “Owner’s Manual Supplement”.
