terior is warmed enough or before you leave the vehi-
cle, be sure to turn the switch off.
"
There is a possibility that people with delicate
skin may suffer slight burns even at low tem-
peratures if he/she uses the seat heater for a
long period of time. When using the heater, al-
ways be sure to warn the persons concerned. " Do not put anything on the seat which insu-
lates against heat, such as a blanket, cushion,
or similar items. This may cause the seat heater
to overheat.
NOTE " Use of the seat heater for a long period of time
while the engine is not running can cause battery
discharge. " When cleaning the seat, do not use benzine,
paint thinner, or any similar materials.
Rear seats
Seatbelts provide maximum restraint when the
occupant sits well back and upright in the seat.
Do not put cushions or any other materials be-
tween occupants and seatbacks or seat cush-
ions. If you do so, the risk of sliding under the
lap belt and of the lap belt sliding up over the
abdomen will increase, and both can result in
serious internal injury or death.

Starting and operating
this in turn can result in engine damage.
In addition, sudden application of engine
brakes when the vehicle is travelling on a slip-
pery surface can lead to wheel locking; as a
consequence, control of the vehicle may be lost
and the risk of an accident increased.
NOTE
Never exceed posted speed limits. !
Driving tips
Do not drive with your foot resting on the clutch pedal
and do not use the clutch to hold your vehicle at a
standstill on an upgrade. Either of those actions may
cause clutch damage.
Do not drive with your hand resting on the shift lever.
This may cause wear on the transmission compo-
nents.
When it is necessary to reduce vehicle speed due to
slow traffic, turning corners, or driving up steep hills,
downshift to a lower gear before the engine starts to
labor.
On steep downgrades, downshift the transmission to
5th, 4th, 3rd or 2nd gear as necessary; this helps to
maintain a safe speed and to extend brake pad life. In this way, the engine provides a braking effect. Re-
member, if you “ride” (over use) the brakes while de-
scending a hill, they may overheat and not work prop-
erly.
The engine may, on rare occasions, knock when the
vehicle rapidly accelerates or rapidly pulls away from
a standstill. This phenomenon is not an indication of a
problem in your vehicle.

Starting and operating
the vehicle is completely stopped. Shifting
while the vehicle is moving may cause damage
to the transmission."
Do not race the engine for more than five sec-
onds in any position except the “N” or “P” po-
sition when the brake is set or the tires are on
blocks. This may cause the automatic transmis-
sion fluid to overheat. " Avoid shifting from one of the forward driving
positions into the “R” position or vice versa un-
til the vehicle has completely stopped. Such
shifting may cause damage to the transmis-
sion. !

Starting and operating
Power steering
The power steering 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 butit will take much more effort.
NOTE
Right after the engine has been started and before
it has warmed up, you may hear a noise coming
from areas adjacent to the power steering pump
which is located at the right-front area of the en-
gine compartment. This noise is normal. It does
not indicate power steering system trouble.
Do not hold the steering wheel at the fully
locked position left or right for more than five
seconds. This may damage the power steering
pump.
Braking !
Braking tips
Never rest your foot on the brake pedal while
driving. This can cause dangerous overheating
of the brakes and needless wear on the brake
pads and linings.
! When the brakes get wet
When driving in rain or after washing the vehicle, the
brakes may get wet. As a result, brake stopping dis-
tance will be longer. To dry the brakes, drive the vehi-
cle at a safe speed while lightly depressing the brake
pedal to heat up the brakes. ! Use of engine braking
Remember to make use of engine braking in addition
to foot braking. When descending a grade, if only the
foot brake is used, the brakes may start working im-
properly because of brake fluid overheating, caused
by overheated brake pads. To help prevent this, shift
into a lower gear to get stronger engine braking.

Driving tips

tance is required because of the added weight and
length caused by attaching the trailer to your vehicle.
1) Left turn
2) Right turn
" Backing up with a trailer is difficult and takes prac-
tice. When backing up with a trailer, never accelerate
or steer rapidly. When turning back, grip the bottom of
the steering wheel with one hand and turn it to the left
for a left turn, and turn it to the right for a right turn." If the ABS warning light illuminates while the vehicle
is in motion, stop towing the trailer and have repairs
performed immediately by the nearest SUBARU deal-er. !
Driving on grades
" Before going down a steep hill, slow down and shift
into lower gear (if necessary, use 1st gear) in order to
utilize the engine braking effect and prevent overheat-
ing of your vehicle’s brakes. Do not make sudden
downshifts. " When driving uphill in hot weather, the air condition-
er may turn off automatically to protect the engine from
overheating. " When driving uphill in hot weather, pay attention to
the water temperature gauge pointer (for all vehicles)
and AT OIL TEMP warning light (for AT vehicles) since
the engine and transmission are relatively prone to
overheating under these conditions. If the water tem-
perature gauge pointer approaches the OVERHEAT
zone or the AT OIL TEMP warning light illuminates,
immediately switch off the air conditioner and stop the
vehicle at the nearest safe place. Refer to the “Engine
overheating” section in chapter 9, and “Warning and
indicator lights” section in chapter 3." If your vehicle has an automatic transmission, avoid
using the accelerator pedal to stay stationary on an
uphill slope instead of using the parking brake or foot
brake. That may cause the transmission fluid to over-
heat. Also, if your vehicle is equipped with an automat-
ic transmission, avoid driving with the gear selector le-
ver in “D” when towing a heavy trailer to prevent fluid

In case of emergency
5. Start the engine of the vehicle with the booster bat-
tery and run it at moderate speed. Then start the en-
gine of the vehicle that has the discharged battery.
6. When finished, carefully disconnect the cables in
exactly the reverse order.Engine overheating
Never attempt to remove the radiator cap until
the engine has been shut off and has fully
cooled down. When the engine is hot, the cool-
ant is under pressure. Removing the cap while
the engine is still hot could release a spray of
boiling hot coolant, which could burn you very
seriously.
If the engine overheats, safely pull off the road and
stop the vehicle in a safe place. ! If steam is coming from the engine
compartment
Turn the engine off and get everyone away from the
vehicle until it cools down. ! If no steam is coming from the engine
compartment
1. Keep the engine running at idling speed.
2. Open the hood to ventilate the engine compart- ment.
