Fog light switch (if equipped)
Pressing the fog lights operate only when the head-
lights are on low beam. Push the fog light switch to
turn the fog lights on.
Press the switch again to turn them off.
The indicator light located on the switch will illuminate
when the fog lights are on.Wiper and washer
In freezing weather, do not use the windshield
washer until the windshield is sufficiently
warmed by the defroster.
Otherwise the washer fluid can freeze on the
windshield, blocking your view.
"Do not operate the washer continuously for
more than ten seconds, or when the washer flu-
id tank is empty. This may cause overheating of
the washer motor. Check the washer fluid level
frequently, such as at fuel stops. " Do not operate the wipers when the wind-
shield or rear window is dry. This may scratch
the glass, damage the wiper blades and cause
the wiper motor to burn out. Before operating
the wiper on a dry windshield or rear window,
always use the windshield washer. " In freezing weather, be sure that the wiper
blades are not frozen to the windshield or rear
window before switching on the wipers. At-UG3512BA

tempting to operate the wiper with the blades
frozen to the window glass could cause not
only the wiper blades to be damaged but also
the wiper motor to burn out. If the wiper blade is frozen to the window glass, be sure to oper-
ate the defroster, windshield wiper deicer (if
equipped) or rear window defogger before turn-
ing on the wiper. "
If the wipers stop during operation because
of ice or some other obstruction on the window,the wiper motor could burn out even if the wiper
switch is turned off. If this occurs, promptly
stop the vehicle in a safe place, turn the ignition
switch to the “LOCK” position and clean the
window glass to allow proper wiper operation. " Use clean water if windshield washer fluid is
unavailable. In areas where water freezes in
winter, use SUBARU Windshield Washer Fluid
or the equivalent. (See the “Windshield washer
fluid” section in chapter 11.)
Also, when driving the vehicle when there are
freezing temperatures, use non-freezing type
wiper blades. " Do not clean the wiper blades with gasoline
or a solvent, such as paint thinner or benzene.
This will cause deterioration of the wiperblades.
NOTE " The wiper operates only when the ignition
switch is in the “ON” or “ACC” position. " Clean your wiper blades and window glass peri-
odically with a washer solution to prevent streak-
ing, and to remove accumulations of road salt or
road film. Keep the washer button depressed at
least for 1 second so that washer solution will be
sprinkled all over the windshield or rear window." Grease, wax, insects or other material on the
windshield or the wiper blade results in jerky wip-
er operation and streaking on the glass. If you can-
not remove those streaks after operating the
washer or if the wiper operation is jerky, clean the
outer surface of the windshield or rear window
and the wiper blades using a sponge or soft cloth
with a neutral detergent or mild-abrasive cleaner.
After cleaning, rinse the window glass and wiper
blades with clean water. The glass is clean if no
beads form on the glass when you rinse with wa- ter. " If you cannot eliminate the streaking even after
following this procedure, replace the wiper blades
with new ones. Refer to the “Replacement of wind-

Windshield wiper deicer (if equipped)
The windshield wiper deicer operates only when the
ignition switch is in the “ON” position.
Before turning on the windshield wiper deicer, remove
any snow from the windshield. To turn on the wind-
shield wiper deicer, push the switch. The indicator light
located on the switch lights up while the windshield
wiper deicer is operating.
The windshield wiper deicer will automatically shut off
after about 15 minutes. If the windshield wiper blades
have been deiced completely before that time, push
the switch to turn it off. It also turns off when the igni-
tion switch is turned to the “ACC” or “LOCK” position.
If deicing is not complete when you restart your vehi-
cle, you have to push the switch to turn the deicer on
again.
NOTE
If your vehicle is equipped with the outside mirror
defogger, the outside mirror defogger operates
while the rear window defogger is operating.
To prevent the battery from being discharged,
do not operate the windshield wiper deicer con-
tinuously for any longer than necessary.UG3515BA

Driving tips
starting.
Keep the door locks from freezing by squirting them
with deicer or glycerin.
Forcing a frozen door open may damage or separate
the rubber weather strips around the door. If the door
is frozen, use hot water to melt the ice, and afterwards
thoroughly wipe the water away.
Use a windshield washer fluid that contains an anti-
freeze solution. Do not use engine antifreeze or other
substitutes because they may damage the paint of the
vehicle. !
Before driving your vehicle
Before entering the vehicle, remove any snow or ice
from your shoes because that could make the pedals
slippery and dangerous.
While warming up the vehicle before driving, check
that the accelerator pedal, brake pedal, and all other
controls operate smoothly.
Clear away ice and snow that has accumulated under
the fenders to avoid making steering difficult. During
severe winter driving, stop when and where it is safe
to do so and check under the fenders periodically. !
Parking in cold weather
Do not use the parking brake when parking for long
periods in cold weather since it could freeze in that po-
sition. Instead, observe the following:
1. Place the shift lever in “1” or “R” for manual trans-
mission vehicles, and in “P” for automatic transmission
vehicles.
2. Use tire stops under the tires to prevent the vehicle
from moving.
When the vehicle is parked in snow or when it snows,
raise the wiper blades off the glass to prevent damageto them.
When the vehicle has been left parked after use on
roads heavily covered with snow, or has been left
parked during a snowstorm, icing may develop on the
brake system, which could cause poor braking action.
Check for snow or ice buildup on the suspension, disc
brakes and brake hoses underneath the vehicle.
If there is caked snow or ice, remove it, being careful
not to damage the disc brakes and brake hoses andABS harness.
Snow can trap dangerous exhaust gases under
your vehicle. Keep snow clear of the exhaust

Wiper operation when snowing
Before driving in cold weather, make sure the wiper
blades are not frozen to the windshield or rear window.
If the wiper blades are frozen to the windshield or rear
window, use the defroster with the airflow control dial
in the “ ” position and the temperature control dial
set for maximum warmth until the wiper blades are
completely thawed out. If your vehicle is equipped with
a wiper deicer, it is helpful to thaw the windshield wiper
blades. To thaw out the rear wiper blade, use the rear
window defogger.
When driving in snow, if frozen snow starts to stick on
the surface of the windshield despite wiper operation,
use the defroster with the airflow control dial in “ ”
and the temperature control dial set for maximum
warmth. After the windshield gets warmed enough to
melt the frozen snow on it, wash it away using the
windshield washer.
Snow stuck on the wiper arm prevents the wiper from
working effectively. If snow is stuck on the wiper arm,
pull off the road to a safe place, then remove it. If you
stop the car at road side, use the hazard warning
flasher to alert other drivers.
We recommend use of non-freezing type wiper blades
(winter blades) during the seasons you could have snow and sub-zero temperatures. Blades of this type
give superior wiping performance in snowy conditions.
Be sure to use blades that are suitable for your vehi-cle. !
Corrosion protection
Refer to the “Corrosion protection” section (chapter
10). ! Snow tires
! All models except WRX-STi
"When replacing original tires with winter
(snow) tires, make sure you use only the same
size, construction and load range as the origi-
nal tires listed on the tire placard. Using other
sizes and construction may affect speedome-
ter/odometer calibration and clearance be-
tween the body and tires. It also may be danger-
ous and lead to loss of vehicle control. " You must install four winter tires that are of
the same size, construction, brand, and load
range. Mixing other sizes or constructions may
result in severe mechanical damage to the drive
