tance is required because of the added weight and
length caused by attaching the trailer to your vehicle.
1) Left turn
2) Right turn
y 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. y 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. T
Driving on grades
y 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.y When driving uphill in hot weather, the air condition-
er may turn off automatically to protect the engine from
overheating.y 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. y 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

10.Before putting the spare tire on, clean the mounting surface of the wheel and hub with a cloth.
11.Put on the spare tire. Replace the wheel nuts.
Tighten them by hand.
Do not use oil or grease on the wheel studs or
nuts when the spare tire is installed. This could
cause the nuts to become loose and lead to an
accident.
12.Turn the jack handle counterclockwise to lower the
vehicle.

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.

In case of emergency
y
Use only the specified towing hook and tie-
down hook. Never use suspension parts or oth-
er body parts for towing or tie-down purposes. y Never use the tie-down hook on the under-
side of the vehicle closest to the muffler for
towing purposes.
„ Using a flat-bed truck
This is the best way to transport your vehicle. Use the
following procedures to ensure safe transportation. 1. Shift the selector lever into the “P” position for au-
tomatic transmission vehicles or “1st” for manual
transmission vehicles.
2. Pull up the parking brake lever firmly.
3. Secure the vehicle onto the carrier properly with
safety chains. Each safety chain should be equally
tightened and care must be taken not to pull the chains
so tightly that the suspension bottoms out.
If your vehicle has a front underspoiler and rear
underspoiler (both optional), be careful not to
scrape them when placing the vehicle on the
carrier and when removing the vehicle from the
carrier.

„Towing with all wheels on the ground
1. Check the transmission and differential oil levels
and add oil to bring it to the upper level if necessary.
2. Release the parking brake and put the transmis-
sion in neutral.
3. The ignition switch should be in the “ACC” position
while the vehicle is being towed.
4. Take up slack in the towline slowly to prevent dam-
age to the vehicle.
y Never turn the ignition switch to the “LOCK”
position while the vehicle is being towed be- cause the steering wheel and the direction of
the wheels will be locked.y
Remember that the brake booster and power
steering do not function when the engine is not
running. Because the engine is turned off, it will
take greater effort to operate the brake pedal
and steering wheel.
y If transmission failure occurs, transport your
vehicle on a flat-bed track. y Do not run the engine while being towed us-
ing this method. Transmission damage could
result if the vehicle is towed with the engine
running. y For vehicles with automatic transmission,
the traveling speed must be limited to less than
20 mph (30 km/h) and the traveling distance to
less than 31 miles (50 km). For greater speeds
and distances, transport your vehicle on a flat-
bed track.

Washing
The best way to preserve your vehicle’s beauty is fre-
quent washing. Wash the vehicle at least once a
month to avoid contamination by road grime.
Wash dirt off with a wet sponge and plenty of luke-
warm or cold water. Do not wash the vehicle with hot
water and in direct sunlight.
Salt, chemicals, insects, tar, soot and bird droppings
should be washed off by using a light detergent, as re-
quired. If you use a light detergent, make certain that
it is a neutral detergent. Do not use strong soap or
chemical detergents. All cleaning agents should be
promptly flushed from the surface and not allowed to
dry there. Rinse the vehicle thoroughly with plenty of
lukewarm water. Wipe the remaining water off with a
chamois or soft cloth.
NOTE
When having your vehicle washed in an automatic
car wash, make sure beforehand that the car wash
is of suitable type. Automatic car wash brushes or
other equipment may damage the rear wiper and
rear/roof spoiler (if equipped).
y When washing the vehicle, the brakes may
get wet. As a result, the brake stopping dis-
tance will be longer. To dry the brakes, drive the
vehicle at a safe speed while lightly pressing
the brake pedal to heat up the brakes. y Do not wash the engine compartment and
area adjacent to it. If water enters the engine air
intake, electrical parts or the power steering flu-
id reservoir, it will cause engine trouble or
faulty power steering respectively.
T Washing the underbody
Chemicals, salts and gravel used for deicing road sur-
faces are extremely corrosive, accelerating the corro-
sion of underbody components, such as the exhaust
system, fuel and brake lines, brake cables, floor pan
and fenders, and suspension.
Thoroughly flush the underbody and inside of the
fenders with lukewarm or cold water at frequent inter-
vals to reduce the harmful effects of such agents.
Mud and sand adhering to the underbody components may accelerate their corrosion.
After driving off-road or on muddy or sandy roads,
wash the mud and sand off the underbody. Carefully

Maintenance and service
the materials in the vehicle may be hazardous if
improperly used or handled, for example, bat-tery acid. y
Your vehicle should only be serviced by per-
sons fully competent to do so. Serious person-
al injury may result to persons not experienced
in servicing vehicles. y Always use the proper tools and make certain
that they are well maintained. y Never get under the vehicle supported only
by a jack. Always use a safety stands to sup-
port the vehicle. y Never keep the engine running in a poorly
ventilated area, such as a garage or other
closed areas. y Do not smoke or allow open flames around
the fuel or battery. This will cause a fire. y Because the fuel system is under pressure,
replacement of the fuel filter should be per-
formed only by your SUBARU dealer.y Wear adequate eye protection to guard
against getting oil or fluids in your eyes. If
something does get in your eyes, thoroughly
wash them out with clean water. y Do not tamper with the wiring of the SRS air-
bag system or seatbelt pretensioner system, or
attempt to take its connectors apart, as that may activate the system or it can render it inop-
erative. The wiring and connectors of these
systems are yellow for easy identification. NEV-
ER use a circuit tester for these wiring.
If your SRS airbag or seatbelt pretensioner
needs service, consult your nearest SUBARU
dealer.
„ Before checking or servicing in the en-
gine compartment
yAlways stop the engine and set the parking
brake firmly to prevent the vehicle from mov-
ing. y Always let the engine cool down. Engine
parts become very hot when the engine is run-
ning and remain hot for some time after the en-
gine is stopped.y Do not spill engine oil, engine coolant, brake
fluid or any other fluid on hot engine compo-
nents. This may cause a fire.y Always remove the key from the ignition
switch. When the ignition switch is in the “ON”
position, the cooling fan may operate suddenly
