lead to loss of vehicle control.
. You must install four tires that are
of the same size, circumferences,
construction, manufacturer,
brand (tread pattern), degree of
wear, speed symbol and load
index. Mixing tires of other sizes,
circumferences or constructions
may result in severe mechanical
damage to the drive train of your
vehicle and may affect ride,
handling, braking and speed-
ometer/odometer calibration. It
also may be dangerous and lead
to loss of vehicle control.
CAUTION
If you use a temporary spare tire to
replace a flat tire, be sure to use the
original temporary spare tire stored
in the vehicle. Using other sizes may
result in severe mechanical damage
to the drive train of your vehicle.
All-Wheel Drive distributes the engine
power to all four wheels. AWD models
provide better traction when driving on
slippery, wet or snow-covered roads and
when moving out of mud, dirt and sand.
By shifting power between the front and
rear wheels, SUBARU AWD can also
provide added traction during acceleration
and added engine braking force duringdeceleration.
Therefore, your SUBARU AWD vehicle
may handle differently than an ordinary
two wheel drive vehicle and it contains
some features unique to AWD. For safety
purposes as well as to avoid damaging
the AWD system, you should keep the
following tips in mind. . An AWD model is better able to climb
steeper roads under snowy or slippery conditions than a two wheel drive vehicle.
There is little difference in handling,
however, during extremely sharp turns or
sudden braking. Therefore, when driving
down a slope or turning corners, be sure
to reduce your speed and maintain an
ample distance from other vehicles. .
Always check the cold tire pressure
before starting to drive. The recom-
mended tire pressure is provided on the
tire placard, which is located under the
door latch on the driver ’s side.
. Frequent driving of an AWD vehicle in
hard driving conditions such as steep hills
or dusty roads will necessitate more
frequent replacement of engine oil, brake
fluid and transmission oil than that speci-
fied in the “Warranty and Maintenance
Booklet ”.
. There are some precautions that you
must observe when towing your vehicle.
