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.

Maintenance and serviceMaintenance schedule
The scheduled maintenance items required to be ser-
viced at regular intervals are shown in the “Warranty
and Maintenance Booklet”.
For details of your maintenance schedule, read the
separate “Warranty and Maintenance Booklet”.Maintenance precautions
When maintenance and service are required, it is rec-
ommended that all work be done by an authorized
SUBARU dealer.
If you perform maintenance and service by yourself,
you should familiarize yourself with the information
provided in this section on general maintenance and
service for your SUBARU.
Incorrect or incomplete service could cause improper
or unsafe vehicle operation. Any problems caused by
improper maintenance and service performed by you
are not eligible for warranty coverage.
yTesting of an All-Wheel Drive vehicle must
NEVER be performed on a single two-wheel dy-
namometer or similar apparatus. Attempting to
do so will result in transmission damage and in
uncontrolled vehicle movement and may cause
an accident or injuries to persons nearby.y Always select a safe area when performing
maintenance on your vehicle.y Always be very careful to avoid injury when
working on the vehicle. Remember that some of
