Limited slip differential (LSD)
(STI)
The LSD provides optimum distribution of
power according to the difference in
revolutions between the right and left
wheels that may be caused by certain
driving conditions, thereby improving driv-
ing stability on snow-covered, muddy or
other slippery roads or when high speed
driving.
CAUTION
.
Never start the engine while a tire
on one side is jacked up, as the
vehicle may move.
.
If one tire is spinning in mud,
avoid continued spinning at high
speed as this could adversely
affect the LSD.
.
If you use a temporary spare tire
to replace a flat tire, be sure to
use the original temporary spare
tire stored in the vehicle. Using
other sizes will adversely affect
the LSD.
Power steering
&
STI
The vehicle is equipped with a hydraulic
power steering system. The power steer-
ing system operates only when the engine
is running.
If you lose power steering assist because
the engine stops or the system fails to
function, you can steer but it will take
much more effort.
CAUTION
Do not hold the steering wheel at the
fully locked position left or right for
more than 5 seconds. This may
damage the power steering pump.
NOTE
Right after the engine has been started
and before it has warmed up, you may
hear a noise coming from areas adja-
cent to the power steering pump which
is located at the right-front area of the
engine compartment. This noise is
normal. It does not indicate power
steering system trouble.
