■Trailer Sway Control
Helps the driver to control trailer
sway by selectively applying brake
pressure for individual wheels and
reducing driving torque when trailer
sway is detected.
■TRC (Traction Control)
Helps to maintain drive power and
prevent the drive wheels from spin-
ning when starting the vehicle or
accelerating on slippery roads
■Active Cornering Assist (ACA)
Helps to prevent the vehicle from
drifting to the outer side by perform-
ing inner wheel brake control when
attempting to accelerate while turn-
ing
■Hill-start assist control
Helps to reduce the backward
movement of the vehicle when
starting on an uphill
■EPS (Electric Power Steering)
Employs an electric motor to
reduce the amount of effort needed
to turn the steering wheel.
■Emergency brake signal
When the brakes are applied sud-
denly, the emergency flashers auto-
matically flash to alert the vehicle
behind.
■Secondary Collision Brake
When the SRS airbag sensor
detects a collision and the system
operates, the brakes and brake
lights are automatically controlled
to reduce the vehicle speed and help reduce the possibility of further
damage due to a secondary colli-
sion.
■When the TRC/VSC/Trailer Sway
Control systems are operating
The slip indicator light will flash while the
TRC/VSC/Trailer Sway Control systems
are operating.
■Disabling the TRC system
If the vehicle gets stuck in mud, dirt or
snow, the TRC system may reduce
power from the engine to the wheels.
Pressing to turn the system off may
make it easier for you to rock the vehicle
in order to free it.
To turn the TRC system off, quickly
press and release .
The “Traction Control Turned OFF” will
be shown on the multi-information dis-
play.

WARNING
●The vehicle hydroplanes while driv- ing at high speed on wet or slick
roads.
■Stopping distance when the ABS
is operating may exceed that of normal 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 pot-holes or uneven surfaces
■TRC/VSC may not operate effec-tively when
Directional control and power may not be achievable while driving on slip-pery road surfaces, even if the
TRC/VSC system is operating. Drive the vehicle carefully in conditions where stability and power may be
lost.
■Active Cornering Assist does not
operate effectively when
●Do not overly rely on Active Corner- ing Assist. Active Cornering Assist
may not operate effectively when accelerating down slopes or driving on slippery road surfaces.
●When Active Cornering Assist fre-quently operates, Active Cornering
Assist may temporarily stop operat- ing to ensure proper operation of the brakes, TRC and VSC.
■Hill-start assist control does not operate effectively when
●Do not overly rely on hill-start assist
control. Hill-start assist control may not operate effectively on steep inclines and roads covered with ice.
●Unlike the parking brake, hill-start assist control is not intended to hold
the vehicle stationary for an extended period of time. Do not attempt to use hill-start assist con-
trol to hold the vehicle on an incline, as doing so may lead to an acci-dent.
■When the TRC/VSC/Trailer Sway Control is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may cause an accident. Exercise particular
care when the indicator light flashes.
■When the TRC/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 the systems to help ensure vehicle stability and driv-ing force, do not turn the
TRC/VSC/Trailer Sway Control sys- tems off unless necessary.Trailer Sway Control is part of the
VSC system and will not operate if VSC is turned off or experiences a malfunction.
■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 pres- sure level.The ABS, TRC Trailer Sway Control
and VSC systems will not function correctly if different tires are installed on the vehicle.
Contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer for further information
when replacing tires or wheels.

WARNING
■Handling of tires and the suspen- sion
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 situations. Depending on many fac-
tors such as the conditions of the vehicle, trailer, road surface and driv-ing 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 sway by turning the steering wheel.
●Begin releasing the accelerator pedal immediately but very gradu-ally to reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehi-cle and trailer should stabilize.
( →P.152)
■Secondary Collision Brake
Do not rely solely upon the Secondary Collision Brake. This system is designed to help reduce the possibil-
ity of further damage due to a second- ary collision, however, that effect changes according to various condi-
tions. Overly relying on the system may result in death or serious injury.

4-6. Driving tips
Driving
Perform the following according to
the driving conditions:
zDo not try to forcibly open a win-
dow or move a wiper that is fro-
zen. Pour warm water over the
frozen area to melt the ice. Wipe
away the water immediately to
prevent it from freezing.
zTo ensure proper operation of
the climate control system fan,
remove any snow that has accu-
mulated on the air inlet vents in
front of the windshield.
zCheck for and remove any
excess ice or snow that may
have accumulated on the exte-
rior lights, vehicle’s roof, chassis,
around the tires or on the brakes.
zRemove 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
conditions.
zPark the vehicle and shift the
shift lever to P (Multidrive), or 1
or R (manual transmission) with-
out setting the parking brake.
The parking brake may freeze up, preventing it from being
released. If the vehicle is parked
without setting the parking brake,
make sure to block the wheels.
Failure to do so may be danger-
ous because it may cause the
vehicle to move unexpectedly,
possibly leading to an accident.
zVehicles with a Multidrive: 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 prob-
lem with the shift lock system. Have
the vehicle inspected by any autho-
rized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer
or legitimate tire retailers immedi-
ately.
Use the correct tire chain size when
mounting the tire chains.
Chain size is regulated for each tire
size.
