■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when
the brakes are applied suddenly, or
if the brakes are applied while driv-
ing on a slippery road surface
■Brake assist
Generates an increased level of
braking force after the brake pedal
is depressed when the system
detects a panic stop situation
■VSC (Vehicle St ability Control)
Helps the driver to control skidding
when swerving suddenly or turning
on slippery road surfaces
■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
The TRC system is also equipped
with the brake LSD function.
■Hill-start assist control
 P.253
■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.
■When the TRC/VSC systems are
operating
The slip indicator will flash while the TRC (Including brake LSD func-
tion)/VSC 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 switch to turn the system
off may make it easier for you to rock the
vehicle in order to free it.
In this case, the brake LSD function
remains on.
To turn the TRC system off, quickly
press and release switch.
The TRC OFF indicator will come on.
Press switch again to turn the sys-
tem back on.
Driving assist systems
To help enhance driving safety
and performance, the following
systems operate automatically
in response to various driving
situations. Be aware, however,
that these systems are supple-
mentary and should not be
relied upon too heavily when
operating the vehicle.
Summary of the driving
assist systems

2584-6. Using other driving systems
*1: Vehicles with an automatic transmission
*2: Vehicles with a manual transmission
■Sounds and vibrations caused by
the ABS, brake assist, TRC and
VSC systems
●A sound may be heard from the
engine compartment when the brake pedal is depressed repeatedly, when
the engine is started or just after the
vehicle begins to move. This sound does not indicate that a malfunction
has occurred in any of these systems.
●Any of the following conditions may
occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the
vehicle body and steering. • A motor sound may be heard after the
vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down
slightly after the ABS is activated.
■EPS operation sound
When the steering wheel is operated, a
motor sound (whirring sound) may be
heard. This does not indicate a malfunc- tion.
■Automatic reactivation of TRC and
VSC systems
After turning the TRC and VSC systems off, the systems will be automatically
reactivated in the following situations:
●When the engine switch is turned off.
●If only the TRC system is turned off, the TRC will turn on when vehicle
speed is more than approximately 50
km/h (31 mph).
If both the TRC and VSC systems are turned off, automatic reactivation will
not occur when vehicle speed
increases.
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is
reduced to prevent the system from
overheating when there is frequent
steering 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 nor-
mal after a little while.
■Automatic deactivation of
“TRACK” mode
When the engine switch is turned off
after driving in “TRACK” mode, the
mode is automatically deactivated.
■Operating conditions of emergency brake signal
When the following three conditions are
met, the emergency brake signal will operate:
●The emergency flashers are off.
●Actual vehicle speed is over 60 km/h
(38 mph).
●The brake pedal is depressed in a
manner that cause the system to judge from the vehicle deceleration
that this is a sudden braking opera-
tion.
■Automatic system cancelation of emergency brake signal
The emergency brake signal will turn off
in any of the following situations:
●The emergency flashers are turned
on.
●The brake pedal is released.
●The system judges from the vehicle
deceleration that is not a sudden brak-
ing operation.
■Customization
Some functions can be customized. ( P.377)

■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 specified size, and that are the same size, same
maker, same brand and tread pat-
tern.
●Maintain the recommended level of
air pressure.
●Do not drive at speeds in excess of
the speed limit or the speed limit specified for the snow tires being
used.
●Use snow tires on a ll, not just some
wheels.
■Driving with tire chains
●When any of the tires are punc-
tured, you can seal the tire tempo- rarily. However, do not use the tire
chain on a sealed tire. If any of the
rear tires are punctured although it is required to use tire chains, con-
tact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
●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 km/h (19 mph),
whichever is lower.
• Avoid driving on bumpy road sur-
faces or over potholes.
• Avoid sudden acceleration, abrupt
steering, sudden braking and shift- ing operations that cause sudden
engine braking.
• Slow down sufficiently before enter- ing a curve to ensure that vehicle
control is maintained.

■If the engine has to be turned off
while driving
Power assist for the brakes and steer-
ing wheel will be lost, making the
brake pedal harder to depress and the steering wheel heavier to turn.
Decelerate as much as possible
before turning off the engine.
If the vehicle is sub-
merged or water on the
road is rising
This vehicle is not designed to
be able to drive on roads that
are deeply flooded with water.
Do not drive on roads where
the roads may be submerged
or the water may be rising. It is
dangerous to remain in the
vehicle, if it anticipated that the
vehicle will be flooded or set a
drift. Remain calm and follow
the following.

■After towing
Make sure to remove the towing eye-
let. If not removed, the SRS airbags may
not deploy correctly if the vehicle is
involved in a frontal collision, or the fuel pump shutoff system may not
operate correctly if involved in a rear
collision.
NOTICE
■To prevent damage to the vehicle when towing using a wheel-lift
type truck
●Do not tow the vehicle from the rear when the engine switch is off. The
steering lock mechanism is not
strong enough to hold the front wheels straight.
●When raising the vehicle, ensure adequate ground clearance for tow-
ing at the opposite end of the raised
vehicle. Without adequate clear-
ance, the vehicle could be dam- aged while being towed.
■To prevent damage to the vehicle when towing with a sling-type
truck
Do not tow with a sling-type truck, either from the front or rear.
■To prevent damage to the vehicle during emergency towing
Do not secure cables or chains to the
suspension components.
■When towing down a long slope
