Starting and operating/Limited slip differential (LSD)
NOTE
. The next time you turn on the
engine, after you turned off the engine
in the Sport (S) mode or Sport Sharp
(S#) mode, the SI-DRIVE mode changes
to the Intelligent (I) mode.
. While the engine is running, if the
malfunction indicator light/CHECK EN-
GINE warning light illuminates, the SI-
DRIVE mode changes to the Sport (S)
mode. In this case, it is not possible to
change to the Sport Sharp (S#) mode or
Intelligent (I) mode.
. If there is a possibility that the
engine could overheat because of a
temperature increase of the engine
coolant, it is not possible to change to
the Sport Sharp (S#) mode. While the
vehicle is in the Sport Sharp (S#) mode,
it changes to the Sport (S) mode when
the engine coolant temperature in-
creases.
. If any of the SI-DRIVE indicators
blink, the SI-DRIVE system may be
malfunctioning. We recommend that
you contact your SUBARU dealer.
Limited slip differential (LSD)
(if equipped)
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.
