Driving assist systems
◆Multi Terrain 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 su
rface, or in off-road conditions (such as
rough roads, sand and mud)
◆Brake assist
Generates an increased leve l 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
◆Active TRAC (Traction Control)
Helps to maintain drive power and prevent the 4 wheels from spinning when starting
the vehicle or accelerating on slippery roads, or in off-road conditions
◆Hill-start assist control
Helps to reduce the backward movement of the vehicle when starting on an incline or
slippery slope
◆AVS (Adaptive Variable Suspension system)
By independently controlling the damping force of the shock absorbers for each of
the 4 wheels according to the road and dr iving conditions, this system helps riding
comfort with superior stee ring stability, and helps good vehicle posture. When
SPORT S+ mode is selected by the drivin g mode select switches, the damping force
is suitable for sporty driving. ( P. 2 8 6 )
◆VGRS (Variable Gear Ratio Steering)
Helps to adjust the wheel turning angle in accordance with the vehicle speed and
steering wheel movement.
◆Trailer Sway Control
Helps the driver to control trailer sway by selectively applying brake pressure for indi-
vidual wheels and reducing engine to rque when trailer sway is detected.
Trailer Sway Control is part of the VSC system and will not operate if VSC turned off
or experiences a malfunction.
To help enhance driving safety and performance, the following systems oper-
ate 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.

■Automatic Active TRAC reactivation
If only the Active TRAC system is turned off, the Active TRAC system will turn on when
vehicle speed increases.
■Automatic Active TRAC, VSC and Trailer Sway Control reactivation
If the Active TRAC, VSC and Trailer Sway Control are turned off, the systems will not
turn on even when vehicle speed increases.
■If the brake system overheats
The brake system may overheat. In this case, a buzzer will sound, and the TRAC OFF
indicator will flash, and Active TRAC and hill- start assist control will be temporarily inop-
erable. In this event, stop the vehicle immediately in a safe place, and allow the brake sys-
tem to cool down sufficiently until the TR AC OFF indicator goes off. (There is no
problem with continuing normal driving.)
■Sounds and vibrations caused by the Mult i Terrain ABS, brake assist, Active TRAC,
VSC, Trailer Sway Control, hill-start assist control and VGRS
●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 condit ions may occur when the above systems are operating.

Any of the following conditions may result in an accident which could cause death or seri-
ous injury:
■The Multi Terrain ABS does not operate effectively when
●The limits of tire gripping performance have been exceeded (such as excessively
worn tires on a snow covered road).
●The vehicle hydroplanes while driving at high speed on a wet or slick road.
■Stopping distance when the Multi Terrain
ABS is operating may exceed that of nor-
mal conditions
The Multi Terrain ABS is not designed to shorten the vehicle’s stopping distance.
Always maintain a safe distance from the vehicl e in front of you, especially in the follow-
ing situations.
●When driving on dirt, gravel or snow-covered roads
●When driving with tire chains
●When driving over bumps in the road
