When driving
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 supplementary and should not be relied
upon too heavily when operating the vehicle.
■ABS (Anti-lock Brake System)
Restrains the vehicle from slipping when driving on slick road surfaces or
in the event of sudden braking.
■BA (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 wh en swerving suddenly or turning on
slippery road surfaces.
■ TRAC (Traction Control)
Maintains drive power and prevents the rear wheels from spinning when
starting the vehicle or accelerating on slippery roads.
■Hill-start assist control
Helps prevent the vehicle from rolling backwards when starting on an
incline or slippery slope. It operat es for approximately 5 seconds at maxi -
mum.
■ VGRS (Variable Gear Ratio Steering) (GS430)
Adjusts the wheel turning angle in accordance with the vehicle speed and
steering wheel movement.
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.
■Active stabilizer suspension system (GS430, if equipped)
Turns at smaller angles to main tain the stable vehicle posture.

■Automatic reactivation of TRAC and VSC
Turning the engine switch OFF after turning of
f the TRAC and VSC systems will
automatically re-enable them.
■Automatic TRAC reactivation
If only the TRAC system is turned off, th e
TRAC system will turn on when the vehi-
cle speed increases.
■Automatic TRAC and VSC reactivation
If only the both TRAC and VSC systems are tur
ned off, the systems will not turn on
even when the vehicle speed increases.
■Sounds and vibrations caused by the ABS, BA, VSC, TRAC, hill-start assist con-
trol and VGRS systems
●A sound may be heard from the engine compartment 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 operat -
ing. 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 af
ter the ABS is activated.
■Hill-start assist control is operational when
●The shift lever is in the “D” or “S” position.
●The brake pedal is not depressed.
■VGRS is disabled in the following situations (GS430)
●During stopping or the steering wheel has been moved for a long time while
driving at lower speeds.
●After the engine is restarted at less than -22°F (-30°C).
■Reduced effectiveness of EPS
The effectiveness of EPS is reduced to prevent the system from overheating when
th
ere 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. Th e system should return to normal within
10 minutes.
