4-5. Using the driving support systems
Driving
■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.

tions may be generated from the brake
system, but this is not a malfunction.
■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, Trailer Sway Control and VSC sys-
tems
After turning the TRC, Trailer Sway Con- trol and VSC systems off, the systems
will be automatically re-enabled 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 increases.If both the TRC and VSC systems are
turned off, automatic re-enabling will not occur when vehicle speed increases.
■Operating conditions of Active Cor-
nering Assist
The system operates when the following occurs.
●TRC/VSC can operate
●The driver is attempting to accelerate while turning
●The system detects that the vehicle is drifting to the outer side
●The brake pedal is released
■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 within 10 minutes.
■Operating conditions of emergency
brake signal
When the following conditions are met, the emergency brake signal will oper-
ates:
●The emergency flashers are off
●Actual vehicle speed is over 55 km/h (35 mph)

ing operation.
■Automatic system cancelation of emergency brake signal
The emergency brake signal will be can-
celed in any of the following situations:
●The emergency flashers are turned
on.
●The system judges from the vehicle
deceleration that is not a sudden brak- ing operation.
■Secondary Collision Brake operat-ing conditions
The system operates when the SRS air- bag sensor detects a collision while the vehicle is in motion.
However, the system does not operate when components are damaged.
■Secondary Collision Brake auto-matic cancelation
The system is automatically canceled in any of the following situations.
●The vehicle speed drops approxi-mately 0 km/h (0 mph)
●A certain amount of time elapses during operation
●The accelerator pedal is depressed a large amount
