Starting and operating

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 ad-

justs the engine’s output and the wheels’

respective braking forces to help maintain

traction and directional control.

y

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 shown by

steady illumination of the Vehicle Dynam-

ics Control operation indicator light.

y

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. Acti-

vation of this function is shown by flashing

of the Vehicle Dynamics Control operation

indicator light.

NOTE

y

Slight twitching of the brake pedal

may be felt when the Vehicle Dynamics

Control system operates; a small de-

gree of vehicle or steering wheel shak-

ing may also be noticed in this situa-

tion. These are normal characteristics

of Vehicle Dynamics Control operation

and are no cause for alarm.
y

When driving off immediately after

starting the engine, a short-lived oper-

ation noise may be noticed coming

from the engine compartment. This

noise is generated as a result of a

check being performed on the Vehicle

Dynamics Control system and is nor-

mal.
y

Depending on the timing of activa-

tion of the brakes, certain situations

may occur just after driving off where

the brake pedal seems to exhibit a jolt-

ing motion. This too is a consequence

of the Vehicle Dynamics Control opera-

tional check and is normal.
y

In the circumstances listed in the fol-

lowing, the vehicle may be more unsta-

ble than it feels to the driver. The Vehi-

cle Dynamics Control System may

therefore operate. Such operation does

not indicate a system fault.

y

Activation of the Vehicle Dynam-

ics Control system is an indica-

tion that the road being travelled

on has a slippery surface; since

having Vehicle Dynamics Control

is no guarantee that full vehicle

control will be maintained at all

times and under all conditions, its

activation should be seen as a

sign that the speed of the vehicle

should be reduced considerably.

y

Whenever suspension compo-

nents, steering components, or an

axle are removed from a vehicle

equipped with Vehicle Dynamics

Control, have an authorized

SUBARU dealer perform an in-

spection of that system.

y

The following precautions should

be observed in order to ensure

that the Vehicle Dynamics Control

system is operating properly:
– All four wheels should be fitted

with tires of the same size, type,

and brand. Furthermore, the

amount of wear should be the

same for all four tires.

– Keep the tire pressure at the

proper level as shown on the

vehicle placard attached to the

driver’s side door pillar.
