When driving
Driving assist systems
When the TRC/VSC systems are operating
The slip indicator light will flash
while the TRC (brake LSD func-
tion)/VSC systems are operat-
ing.
To help enhance driving safety and performance, the following sys-
tems operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavily when operating the vehicle.
ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving 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 Stability 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.
EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel

228 2-4. Using other driving systems
Turning off both TRC and VSC systems
To turn the TRC and VSC systems off, press and hold for more than 3
seconds while the vehicle is stopped.
The “TRC OFF” indicator light and the VSC off indicator light will come on.
In this case, the brake LSD function remains on.
Press the button again to turn the systems back on.
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 malfunction.
Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automati-
cally reactivated in the following situations:
Vehicles without a smart entry & start system: When the engine switch is
turned to “LOCK” position
Vehicles with a smart entry & start system: When the “ENGINE START
STOP” 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.

When driving
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 normal after a little while.
Automatic deactivation of “VSC SPORT” mode
Vehicles without a smart entry & start system
When the engine switch is turned to “LOCK” position after driving in “VSC
SPORT” mode, the mode is automatically deactivated.
Vehicles with a smart entry & start system
When the “ENGINE START STOP” switch is turned off after driving in “VSC
SPORT” mode, the mode is automatically deactivated.
CAUTION
The ABS does not operate effectively when
Tires with inadequate gripping ability are used (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 is operating may exceed that of nor-
mal 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 in the following situ-
ations:
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 surfaces
TRC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
