!Driving with pets
Unrestrained pets can interfere with your driving and
distract your attention from driving. In a collision or
sudden stop, unrestrained pets or cages can be
thrown around inside the vehicle and hurt you or your
passengers. Besides, the pets can be hurt under
these situations. It is also for their own safety that pets
should be properly restrained in your vehicle. Restrain
a pet with a special traveling harness which can be se-
cured to the rear seat with a seatbelt or use a pet car-
rier which can be secured to the rear seat by routing a
seatbelt through the carrier’s handle. Never restrain
pets or pet carriers in the front passenger’s seat. For
further information, consult your veterinarian, local an-
imal protection society or pet shop. ! Tire pressures
Check and, if necessary, adjust the pressure of each
tire (including the spare) at least once a month and be-
fore any long journey.
Check the tire pressure when the tires are cold. Use a
pressure gauge to adjust the tire pressures to the val-
ues shown on the tire placard.
Refer to the “Tires and wheels” section in chapter 11
for detailed information.
Driving at high speeds with excessively low tire
pressures can cause the tires to deform severe-
ly and to rapidly become hot. A sharp increase
in temperature could cause tread separation,
and destruction of the tires. The resulting loss
of vehicle control could lead to an accident.
! California proposition 65 warning
Engine exhaust, some of its constituents, and
certain vehicle components contain or emit
chemicals known to the State of California to
cause cancer and birth defects or other repro-
ductive harm. In addition, certain fluids in vehi-
cles and certain components of product wear
contain or emit chemicals known to the State of
California to cause cancer and birth defects or
other reproductive harm.

collision, consult your SUBARU dealer. "
Tampering with or disconnecting the sys-
tem’s wiring could result in accidental activa-
tion of the seatbelt pretensioner and/or SRS air-
bag or could make the system inoperative,
which may result in serious injury. The wiring
harnesses of the seatbelt pretensioner and SRS
airbag systems are covered with yellow insula-
tion and the connectors of the system are yel-
low for easy identification. Do not use electrical
test equipment on any circuit related to the
seatbelt pretensioner and SRS airbag systems.
For required servicing of the seatbelt preten-
sioner, see your nearest SUBARU dealer.
The front sub sensors are located in both front
fenders and the SRS airbag control module in-
cluding the impact sensors is located under the
center console. If you need service or repair in
those areas or near the front seatbelt retrac-
tors, we recommend that you have an autho-
rized SUBARU dealer perform the work.
NOTE
If the front part of the vehicle is damaged in an ac-
cident to the extent that the seatbelt pretensioner
does not operate, contact your SUBARU dealer as
soon as possible. ! Precautions against vehicle modifica- tion
Always consult your SUBARU dealer if you want to in-
stall any accessory parts to your vehicle.
Do not perform any of the following modifica-
tions. Such modifications can interfere with
proper operation of the seatbelt pretensioners. " Attachment of any equipment (bush bar,
winches, snow plow, skid plate, etc.) other than
SUBARU genuine accessory parts to the front
end." Modification of the suspension system or
front end structure." Installation of a tire of different size and con-
struction from the tires specified on the tire
placard attached to the driver’s door jamb.

vehicles with SRS side airbags only) " Installation of additional fabric or leather
on the front seat (for vehicles with SRS side
airbags only)
" Installation of additional electrical/electronic
equipment such as a mobile two-way radio on
or near the SRS airbag system components
and/or wiring is not advisable. This could inter-
fere with proper operation of the SRS airbag
system.
Do not perform any of the following modifica-
tions. Such modifications can interfere with
proper operation of the SRS airbag system." Attachment of any equipment (brush bar,
winches, snow plow, skid plate, etc.) other than
SUBARU genuine accessory parts to the front
end. " Modification of the suspension system or
front end structure. " Installation of a tire of different size and con-
struction from the tires specified on the tire placard attached to the driver’s door jamb. "
Attachment of any equipment (side steps or
side sill protectors, etc.) other than SUBARU
genuine accessory parts to the side body (for
vehicles with side airbags only).
Always consult your SUBARU dealer if you want to in-
stall any accessory parts to your vehicle.

Instruments and controls

tires are not all the same size and brand, the rear
differential will be heavily loaded when the vehicle
is driven, resulting in an abnormally high oil tem-
perature. "The rear differential oil will deteriorate if its tem-
perature increases enough for the rear differential
oil temperature warning light to come on. It is ad-
visable to have the rear differential oil replaced as
soon as possible. ! ABS warning light
The ABS warning light comes on when the ignition
switch is turned to the “ON” position and goes out after
about two seconds.
This is an indication that the ABS system is working
properly.
If the warning light behaves as follows, the ABS
system may not work properly.
When the warning light is on, the ABS function
shuts down; however, the conventional brake
system continues to operate normally." The warning light does not come on when the
ignition switch is turned to the “ON” position." The warning light comes on when the ignition switch is turned to the “ON” position, but it
does not go out even when the vehicle speed
exceeds approximately 8 mph (12 km/h)."
The warning light comes on during driving.
If these occur, have the ABS system repaired at
the first available opportunity by your SUBARU
dealer.
With a vehicle equipped with an EBD system, the ABS
warning light comes on together with the brake system
warning light if the EBD system becomes faulty. For
further details of the EBD system fault warning, refer to “Brake system warning light”.
NOTE
If the warning light behavior is as described be-
low, the ABS system may be considered normal." The warning light comes on right after the en-
gine is started but goes out immediately, remain-
ing off." The warning light remains on after the engine
has been started, but it goes out when the vehicle
speed reaches about 8 mph (12 km/h)." The warning light comes on during driving, but
it goes out immediately and remains off.
