WARNING
■When using Crawl Control
● Do not overly rely on Crawl Control. This function does not ext end the
vehicle’s performance limitations. Always check the terrain tho roughly and
drive safely.
● The recommended speed modes for the listed terrains ( P. 324) are only
a reference. The selected mode may not be suitable to actual off-road con-
ditions due to factors such as the type or unevenness of the te rrain or the
degree of incline. Check the actual terrain thoroughly and drive safely.
● After activating Crawl Control, make sure that the Crawl Control indicator
comes on. If the indicator flashes, the vehicle is not under system control.
■ Conditions under which the syst em may not operate correctly
When driving on the following surfaces, the system may not be able to
maintain a fixed low speed, which may result in an accident:
● Extremely steep inclines
● Extremely uneven surfaces
● Snow-covered roads, or other slippery surfaces

WARNING
■When the TRAC/VSC/Trailer Sway Control is activated
The slip indicator light flashes. Always drive carefully.
Reckless driving may cause an accident. Exercise particular car e when the
indicator light flashes.
■ When TRAC/VSC/Trailer Sway Control systems are turned off
Be especially careful and drive at a speed appropriate to the r oad condi-
tions. As these are systems to help ensure vehicle stability and driving
force, do not turn the TRAC/VSC/Trailer Sway Control systems off unless
necessary.
■ Replacing tires
Make sure that all tires are of the specified size, brand, trea d pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, Multi Terrain ABS, TRAC, VSC and Trailer Sway Control will not
function correctly if different tires are installed on the vehi cle.
Contact your Toyota dealer for further information when replaci ng tires or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspensio n 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 info rmation 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 whee l.
● Begin releasing the accelerator pedal immediately but very grad ually 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. ( P. 202)

Perform the following according to the driving conditions:
● Do not try to forcibly open a window or move a wiper that is fr ozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to p revent 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 ic e 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 roa d con-
ditions.
● Park the vehicle and move the shift lever to P without setting the
parking brake. The parking brake may freeze up, preventing it from
being released. If the vehicle is parked without setting the pa rking
brake, make sure t o block the wheels.
Failure to do so may be dangerou s because it may cause the vehi-
cle to move unexpectedly, pos sibly leading to an accident.
● If the vehicle is parked without setting the parking brake, confirm
that the shift lever c annot be moved out of P
*.
*: The shift lever will be locked if it is attempted to be shifte d 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 syst em. Have the
vehicle inspected by your Toyota dealer immediately.
