WARNING
Any of the following conditions may result in an accident which could cause
death or serious injury:
■ The Multi Terrain ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded (suc h as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on the wet or slick
road.
■ Stopping distance when the Multi Terrain ABS is operating may exceed
that of normal conditions
The Multi Terrain ABS is not designed to shorten the vehicle’s stopping dis-
tance. Always maintain a safe distance from the vehicle in fron t 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 roads
■ Active TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the Active TRAC is operating.
Do not drive the vehicle in conditions where stability and powe r may be lost.
■ If the hill-start assist control does not operate effectively
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 in ice.
■ When Active TRAC, VSC and Trailer Sway Control are off
Be especially careful and drive at a speed appropriate to the r oad condi-
tions. As there are systems to help ensure vehicle stability an d driving force,
do not turn off Active TRAC, VSC and Trailer Sway Control unless neces-
sary.

■
Replacing tires
Make sure that all tires are of the same size, brand, tread pat tern and
total load capacity. In addition, make sure that the tires are inflated to
the specified tire pressure level.
The Multi Terrain ABS, Active TR AC, VSC and Trailer Sway Control will
not function correctly if different tires are fitted on the veh icle.
Contact your Toyota dealer for further information when replaci ng tires
or wheels.
■Handling of tires and suspension
Using tires with any kind of probl em or modifying the suspension will
affect the driving assist system s, and may cause the system to malfunc-
tion.
■ 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 Swa y Control sys-
tem may not be effective. Refer to your trailer owner’s manual for informa-
tion 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 swaying by turning the steering w heel.
● 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. 207)
