4RUNNER (U)_(OM35B37U)■
Reactivation of the VSC and Trailer Sway Control system linked to vehi-
cle speed (2WD models)
When the TRAC system is turned off and the AUTO LSD system is turned on,
the VSC and Trailer Sway Control system will turn on when vehicle speed
increases. However, when the TRAC, VSC and Trailer Sway Control systems
are turned off, the systems will not turn on even when vehicle speed
increases.
■ Reactivation of the TRAC/VSC/Trail er Sway Control systems (4WD mod-
els)
If the TRAC/VSC/Trailer Sway Control systems are turned off, the systems
will not turn on even when vehicle speed increases.
CAUTION
■ The ABS and Multi Terrain ABS do 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 or Multi Terrain ABS is operating may
exceed that of normal conditions
The ABS and Multi Terrain ABS are 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 roads with 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.
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 and Trailer Sway Control are activated
The slip indicator light flashes. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care 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 road 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, tread 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, VSC and Trailer Sway Control will not function
correctly if different tires are fitted on the vehicle.
Contact your Toyota dealer 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.
■ 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 information 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 wheel.
● Begin releasing the accelerator pedal immediately but very gradually 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. 188)

■Brake fluid can absorb moisture from the air
Excess moisture in the brake fluid can cause a dangerous loss of braking effi-
ciency. Use only newly opened brake fluid.
CAUTION
■When filling the reservoir
Take care as brake fluid can harm your hands and eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with clean
water immediately.
If you still experience discomfort, see a doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear out or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, there may be a serious problem.
