combustion), have your vehicle checked and repaired
by an authorized SUBARU dealer.yDo not apply undercoating or rust prevention treat-
ment to the heat shield of catalytic converter and the
exhaust system.Periodic inspections
To keep your vehicle in the best condition at all times,
always have the recommended maintenance services
listed in the maintenance schedule in the “Warranty
and Maintenance Booklet” performed at the specified
time or mileage intervals.

Driving tips
y
Always check your brakes for effectiveness immedi-
ately after driving in sand, mud or water. Do this by
driving slowly and stepping on the brake pedal. Re-
peat that process several times to dry out the brake
discs and brake pads.y Do not drive or park over or near flammable materi-
als such as dry grass or fallen leaves, as they may
burn easily. The exhaust system is very hot while the
engine is running and right after engine stops. This
could create a fire hazard. y After driving through tall grass, mud, rocks, sand,
rivers, etc., check that there is no grass, bush, paper,
rags, stones, sand, etc. adhering to or trapped on the
underbody. Clear off any such matter from the under-
body. If the vehicle is used with these materials
trapped or adhering to the underbody, a mechanical
breakdown or fire could occur.y Secure all cargo carried inside the vehicle and make
certain that it is not piled higher than the seatbacks.
During sudden stops or jolts, unsecured cargo could
be thrown around in the vehicle and cause injury. Do
not pile heavy loads on the roof. Those loads raise the
vehicle’s center of gravity and make it more prone totip over. y If you must rock the vehicle to free it from sand or
mud, depress the accelerator pedal slightly and move
the selector lever back and forth between “D” and “R” repeatedly. Do not race the engine. For the best pos-
sible traction, avoid spinning the wheels when trying to
free the vehicle. y
When the road surface is extremely slippery, you
can obtain better traction by starting the vehicle with
the transmission in 2nd than 1st (both for MT and AT). y Never equip your vehicle with tires larger than those
specified in this manual. y Wash the vehicle’s underbody after off-road driving.
Suspension components are particularly prone to dirt
buildup, so they need to be washed thoroughly.y Frequent driving of an AWD vehicle under hard-driv-
ing conditions such as rough roads or off roads will ne-
cessitate more frequent replacement of engine oil,
brake fluid and transmission oil than that specified in
the maintenance schedule described in the “Warranty
and Maintenance Booklet”.
Remember that damage done to your SUBARU while
operating it off-road and not using common sense pre-
cautions such as those listed above is not eligible for
warranty coverage.

Driving tips
and insert the receiver cover onto the hitch receiver tube.y
Place the dust cap over the four-pin connector of the
hitch wire harness to protect against possible damage.y Occasionally lubricate terminals of the four-pin con-
nector using the terminal grease.Trailer 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 engine, drivetrain,
brakes, tires and suspension and has an adverse ef-
fect 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.
yAdequate size trailer brakes are required
when the trailer and its cargo exceed 1,000 lbs
(453 kg) total weight. y Before towing a trailer, check the trailer total
weight, GVW, GAWs and tongue load. Make
sure the load and its distribution in your vehicle
and trailer are acceptable.
T Total trailer weight
Total trailer weight
The total trailer weight (trailer weight plus its cargo
load) must never exceed the maximum weight shown
below.

To help prevent corrosion
Wash the vehicle regularly to prevent corrosion of the
body and suspension components. Also, wash the ve-
hicle promptly after driving on any of the following sur- faces: y roads that have been salted to prevent them from
freezing in winter y mud, sand, or gravel
y coastal roads
After the winter has ended, it is recommended that the
underbody be given a very thorough washing.
Before the beginning of winter, check the condition of
underbody components, such as the exhaust system,
fuel and brake lines, brake cables, suspension, steer-
ing system, floor pan, and fenders. If any of them are
found to be rusted, they should be given an appropri-
ate rust prevention treatment or should be replaced.
Contact your SUBARU dealer to perform this kind of
maintenance and treatment if you need assistance.
Repair chips and scratches in the paint as soon as you find them.
Check the interior of the vehicle for water and dirt ac- cumulation under the floor mats because that could
cause corrosion. Occasionally check under the mats
to make sure the area is dry.
Keep your garage dry. Do not park your vehicle in a
damp, poorly ventilated garage. In such a garage, cor-
rosion can be caused by dampness. If you wash the
vehicle in the garage or put the vehicle into the garage
when wet or covered with snow, that can cause damp-ness.
If your vehicle is operated in cold weather and/or in ar-
eas where road salts and other corrosive materials are
used, the door hinges and locks, trunk lid lock, and
hood latch should be inspected and lubricated period-
ically.
