Starting and operating/Vehicle Dynamics Control system

of the Vehicle Dynamics Control system is reduced and
this should be taken into account when driving the vehicle in such a condition.
. If non-matching tires are used,
the Vehicle Dynamics Control
system may not operate correctly.
. The Vehicle Dynamics Control
system helps prevent unstable
vehicle motion such as skidding
using control of the brakes and
engine power. Do not turn off the
Vehicle Dynamics Control system unless it is absolutely necessary. If you must turn off the
Vehicle Dynamics Control system, drive very carefully based
on the road surface condition.
In the event of wheelspin and/or skidding
on a slippery road surface and/or during
cornering and/or an evasive maneuver,
the Vehicle Dynamics Control system
adjusts the engine’s output and the
wheels’ respective braking forces to help
maintain traction and directional control.
. Traction Control Function
The traction control function is designed to
prevent spinning of the driving wheels on
slippery road surfaces, thereby helping to

maintain traction and directional control.
Activation of this function is indicated by
steady illumination of the Vehicle Dynamics Control operation indicator light.
. Skid Suppression Function
The skid suppression function is designed
to help maintain directional stability by
suppressing the wheels’ tendency to slide
sideways during steering operations. Activation of this function is indicated by
flashing of the Vehicle Dynamics Control
operation indicator light.

NOTE
. The Vehicle Dynamics Control system may be considered normal when
the following conditions occur.
– Slight twitching of the brake
pedal is felt.
– The vehicle or steering wheel
shakes to a small degree.
– An operating sound from the
engine compartment is heard
briefly when starting the engine
and when driving off after starti
