succession. (  P. 513)
However, do not touch the engine switch wh ile driving except in an emergency. Turn-
ing the engine off while drivin g will not cause loss of steering or braking control, but
the power assist to these systems will be lost . This will make it more difficult to steer
and brake, so you should pull over and stop the vehicle as soon as it is safe to do so. ●
If the engine switch is operated while the vehicle is running, a warning message will be
shown on the multi-information display and a buzzer sounds. ●
When restarting the engine after it was turn ed off while driving, shift the shift lever to

Driving
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 increase d 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
◆ Active TRAC (Traction Control) Helps to maintain drive power and prevent the 4 wheels from spinning when starting
the vehicle or accelerating on slippe ry 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 th e road and driving conditions, this system helps riding
comfort with superior steering stabilit y, and helps good vehicle posture. When
SPORT S+ mode is selected by the drivin g mode select switch, the damping force is
suitable for sporty driving. (  P. 290)
◆ 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 perf ormance, the following systems oper-
ate automatically in response to variou s driving situations. Be aware, however,
that these systems are supplementary and should not be relied upon too heav-
ily when operating the vehicle.
