7-304. Insert the screwdriver into the hole.
5. Push down on the screwdriver, push down the button and move the
selector lever from the
“P” to the “N” position.
6. Remove the screwdriver from the hole. Depress the brake pedal and
start the engine.
Take your vehicle to the nearest SUBARU dealer immediately to have the
system repaired.
Rear viscous limited slip differential (LSD) (if equipped)
CAUTION
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 continued spinning at
high speed as this could adversely affect the LSD. If a different size rear tire is temporarily used (as in an emer-
gency), it will adversely affect the LSD. Always replace it with aregular size tire as soon as possible.
The LSD provides optimum distribution of power according to the differ-
ence in revolutions between the right and left rear wheels that may be
caused by certain driving conditions, thereby improving driving stability
on snow-covered, muddy or other slippery roads.

8-28Trailer towing
Your car is designed and intended to be used primarily as a passenger-
carrying vehicle. Towing a trailer puts additional loads on your car
’s en-
gine, drivetrain, brakes, tires and suspension and has an adverse effect
on fuel economy.
If you do decide to tow a trailer, your safety and satisfaction depend
upon proper use of correct equipment and cautious operation of your ve-
hicle. Seek the advice of your SUBARU dealer to assist you in purchas-
ing a hitch and other necessary towing equipment appropriate for your
vehicle. In addition, be sure to follow the instructions on correct installa-
tion and use provided by the trailer and other towing equipment
manufacturers.
SUBARU assumes no responsibility for injuries or vehicle damage that
result from trailer towing equipment, or from any errors or omissions in
the instructions accompanying 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 “Maintenance 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, transmis-
sion, differential, wheel bearings, etc.) for the first 1,000 miles (1,600km) of driving. Maximum load limits
WARNING
Never exceed the maximum load limits explained below. Exceed- ing the maximum load limits could cause personal injury and/or
vehicle damage.

9-16the radiator. After the pressure has been fully released, remove the
cap by pressing down and turning it.
Towing
WARNING
Never tow AWD vehicles (both AT and MT) with the front wheelsraised off the ground while the rear wheels are on the ground, orwith the rear wheels raised off the ground while the front wheelsare on the ground. This will cause the vehicle to spin away due tothe operation or deterioration of the center differential.
HG9013BA
If towing is necessary, it is best done by your SUBARU dealer or a com-
mercial towing service. Observe the following procedures for safety.
Towing and tie-down hooks
CAUTION
Use only specified towing hooks and tie-down hooks. Never
use suspension parts or other body parts for towing or tie-downpurposes. Never use the tie-down hook closest to the muffler under the
vehicle for towing purposes. Do not apply excessive lateral load to the towing hooks.

CAUTION
If transmission failure occurs, transport your vehicle on a flat-
bed truck. Do not run the engine while being towed in this method. Trans-
mission damage could result if the vehicle is towed with theengine 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 transmission in neutral.
3. The ignition switch should be in the “ACC” position while the ve-
hicle is being towed.
4. Take up slack in the towline slowly to prevent damage to the ve-hicle.

Checking the gear oil level CAUTION
If the vehicle requires frequent refilling, there may be an oil leak. If you suspect a problem, have the vehicle checked at your
SUBARU dealer.
Your vehicle may be equipped with a rear differential protector. The
differential protector provides protection to the rear differential assem-
bly during off-road use. Removal of the rear differential protector is not
required when checking the oil level.
