Starting and operating
Rear viscous limited slip differential
(LSD) (if equipped)
"
Never start the engine while a tire on one side
is jacked up, as the vehicle may move. " If one rear tire is spinning in mud, avoid con-
tinued spinning at high speed as this could ad-
versely affect the LSD. " If a different size rear tire is temporarily used
(as in an emergency), it will adversely affect the
LSD. Always replace it with a regular size tire as
soon as possible.
The LSD provides optimum distribution of power ac-
cording to the difference in revolutions between the
right and left rear wheels that may be caused by cer-
tain driving conditions, thereby improving driving sta-
bility on snow-covered, muddy or other slippery roads.
Power steering
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.
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 but
it 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.

Trailer towing
Your vehicle is designed and intended to be used pri-
marily as a passenger-carrying vehicle. Towing a trail-
er puts additional loads on your vehicle’s engine, driv-
etrain, brakes, tires and suspension and has an ad-
verse effect on fuel economy.
If you do decide to tow a trailer, your safety and satis-
faction depend upon proper use of correct equipment
and cautious operation of your vehicle. Seek the ad-
vice of your SUBARU dealer to assist you in purchas-
ing a hitch and other necessary towing equipment ap-
propriate for your vehicle. In addition, be sure to follow
the instructions on correct installation and use provid-
ed by the trailer and other towing equipment manufac-
turers.
SUBARU assumes no responsibility for injuries or ve-
hicle damage that result from trailer towing equipment,
or from any errors or omissions in the instructions ac-
companying such equipment or for your failure to fol-
low the proper instructions. !Warranties and maintenance
SUBARU warranties do not apply to vehicle damage
or malfunction caused by trailer towing. If you use your
vehicle to tow a trailer, more frequent maintenance will
be required due to the additional load. (Refer to “Main- tenance schedule under severe driving conditions” in
the “Warranty and Maintenance Booklet”.)
Under no circumstances should a trailer be towed with
a new vehicle or a vehicle with any new powertrain
component (engine, transmission, differential, wheel
bearings, etc.) for the first 1,000 miles (1,600 km) of
driving. !
Maximum load limits
Never exceed the maximum load limits ex-
plained below. Exceeding the maximum load
limits could cause personal injury and/or vehi-
cle damage.
"Adequate size trailer brakes are required
when the trailer and its cargo exceed 1,000 lbs
(453 kg) total weight. " Before towing a trailer, check the trailer total
weight, GVW, GAWs and tongue load. Make
sure the load and its distribution in your vehicle

In case of emergency
– CONTINUED –
Confirm that the cooling fan is turning. If the fan is not
turning, immediately turn the engine off and contact
your authorized dealer for repair.
3. After the engine coolant temperature has dropped, turn off the engine.
If the temperature gauge stays at the overheated
zone, turn the engine off.
4. After the engine has fully cooled down, check the
coolant level in the reserve tank.
If the coolant level is below the “MIN” mark, add cool-
ant up to the “MAX” mark.
5. If there is no coolant in the reserve tank, add cool-
ant to the reserve tank. Then remove the radiator cap
and fill the radiator with coolant.
If you remove the radiator cap from a hot radiator, first
wrap a thick cloth around the radiator cap, then turn
the cap counterclockwise slowly without pressing
down until it stops. Release the pressure from the ra-
diator. After the pressure has been fully released, re-
move the cap by pressing down and turning it.Towing
Never tow AWD vehicles (both AT and MT) with
the front wheels raised off the ground while the
rear wheels are on the ground, or with the rear
wheels raised off the ground while the front
wheels are on the ground. This will cause the
vehicle to spin away due to the operation or de-
terioration of the center differential.
If towing is necessary, it is best done by your SUBARU

In case of emergency
!
Towing with all wheels on the ground
"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." 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.
" If transmission failure occurs, transport your
vehicle on a flat-bed truck. " 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. " 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 truck.
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.UB9219BA
