Vdc System Monitor - Subaru 2004 Legacy Owner's Manual

Starting and operating
driving off where the brake pedal seems to exhibit
a jolting motion. This too is a consequence of the
VDC operational check and is normal.
In the circumstances listed below, the vehicle
may be more unstable than it feels to the driver.
The Vehicle Dynamics Control System may there-
fore operate. Such operation does not indicate a
system fault.
on gravel-covered or rutted roads
on unfinished roads
when the vehicle is towing a trailer
when the vehicle is fitted with snow tires or
winter tires
Activation of the VDC system will cause opera-
tion of the steering wheel to feel slightly different
compared to that for normal conditions.
Even if the vehicle is equipped with a VDC sys-
tem, it is important that winter tires be used when
driving on snow-covered or icy roads. (All four
wheels should be fitted with tires of the same size
and brand).
It is always important to reduce speed when ap-
proaching a corner, even if the vehicle is equipped
with VDC.
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
7-36
tires. If these precautions are not observed and
non-matching tires are used, it is quite possible
that the VDC system will be unable to operate cor-
rectly as intended.
Always turn off the engine before replacing a
tire as failure to do so may render the VDC system
unable to operate correctly.
