heating SUBARU LEGACY 2003 3.G User Guide

4-22Air filtration system (if equipped) If your vehicle
’s air conditioning system is equipped with a optional air
filtration system, replace the filter element according to the replacement
schedule shown below. This schedule should be followed to maintain the
filter’ s dust collection ability. Under extremely dusty conditions, the filter
should be replaced more frequently. Since the filter element is a viscous
type, it is unnecessary to clean or wash the element. Have your filter
checked or replaced by your SUBARU dealer.
Replacement schedule: Every 12 months or 9,300 miles (15,000 km) whichever comes first
NOTE The filter can influence the air conditioning, heating and defroster performance if not properly maintained.

Rear passenger ’s cup holder (if equipped)
HB6024BAHB7009CA
The rear passenger ’s cup holder is located on the lower side of the
back of the center console. To use the cup holder, open the lid by
pulling its upper edge.
Cigarette lighter socket (if equipped)
CAUTION
The electrical power socket located on the lower part of the
instrument panel is originally designed to use a SUBARU genuine
cigarette lighter plug. Do not use non-genuine cigarette lighterplugs in the socket. Doing so may cause a short-circuit and over-heating, resulting in a fire. If the socket is ever used for a plug-in accessory such as a
mobile phone, they may damage the portion of the socket ’s inter-
nal mechanism that causes a cigarette lighter plug to “pop out ”
after its lighter element is heated. Therefore, do not place a ciga-rette lighter plug in a socket that has been used, even once, to
power a plug-in accessory. Doing so may cause the plug to stickand overheat, creating a potential fire hazard. Do not place any foreign objects, especially metal ones such
as coins or aluminum foil, into the socket. That could cause ashort circuit.

HB6011BA
The electrical power socket located on the lower part of the instrument
panel can be used as cigarette lighter socket. A cigarette lighter plug is
an optional accessory. It is available from your SUBARU dealer.
The cigarette lighter socket may also be used as a power source for anin-car use electrical appliance.Use with a cigarette lighter
WARNING
To avoid being burned, never grasp the lighter by the end withthe heating element. Doing so could result in injury and couldalso damage the heating element.
CAUTION
Do not hold the lighter pushed in, because it will overheat.

Power steering
CAUTION
Do not hold the steering wheel at the fully locked position left or right for more than five seconds. This may damage the powersteering pump.
The power steering system operates only when the engine is running.
If you lose power steering assist because the engine stops or the system
fails to function, you can steer but it will take much more effort. NOTE Right after the engine has been started and before it has warmed up, you may hear a noise coming from areas adjacent to the powersteering pump which is located at the right-front area of the enginecompartment. This noise is normal. It does not indicate power steer-ing system trouble. Braking Braking tips
WARNING
Never rest your foot on the brake pedal while driving. This can
cause dangerous overheating of the brakes and needless wearon the brake pads and linings.
When the brakes get wet
When driving in rain or after washing the vehicle, the brakes may get
wet. As a result, brake stopping distance will be longer. To dry the
brakes, drive the vehicle at a safe speed while lightly depressing thebrake pedal to heat up the brakes. Use of engine braking
Remember to make use of engine braking in addition to foot braking.

7-32When descending a grade, if only the foot brake is used, the brakes
may start working improperly because of brake fluid overheating,
caused by overheated brake pads. To help prevent this, shift into a
lower gear to get stronger engine braking.
Braking when a tire is punctured
Do not depress the brake pedal suddenly when a tire is punctured.
This could cause a loss of control of the vehicle. Keep driving straight
ahead while gradually reducing speed. Then slowly pull off the roadto a safe place.
Brake system Two separate circuits
Your vehicle has two separate circuit brake systems. Each circuit
works diagonally across the vehicle. If one circuit of the brake system
should fail, the other half of the system still works. If one circuit fails,
the brake pedal will go down much closer to the floor than usual and
you will need to press it down much harder. And a much longer dis-
tance will be needed to stop the vehicle. Brake booster
The brake booster uses engine manifold vacuum to assist braking
force. Do not turn off the engine while driving because that will turn off
the brake booster, resulting in poor braking power.The brakes will continue to work even when the brake booster com-
pletely stops functioning. If this happens, however, you will have to
push the pedal much harder than normal and the braking distance
will increase.

Driving on grades
Before going down a steep hill, slow down and shift into lower gear
(if necessary, use 1st gear) in order to utilize the engine braking effect
and prevent overheating of your vehicle ’s brakes. Do not make sud-
den downshifts. When driving uphill in hot weather, the air conditioner may turn off
automatically to protect the engine from overheating. When driving uphill in hot weather, pay attention to the water tem-
perature gauge pointer (for all vehicles) and AT OIL TEMP warning
light (for AT vehicles) since the engine and transmission are relatively
prone to overheating under these conditions. If the water temperature
gauge pointer approaches the OVERHEAT zone or the AT OIL TEMP
warning light illuminates, immediately switch off the air conditioner
and stop the vehicle at the nearest safe place. Refer to the “Engine
overheat” section in chapter 9, and “Warning and indicator lights ”
section in chapter 3. If your vehicle has an automatic transmission, avoid using the
accelerator pedal to stay stationary on an uphill slope instead of usingthe parking brake or foot brake. That may cause the transmission fluidto overheat. Also, if your vehicle is equipped with an automatic trans-mission, avoid driving with the gear selector lever in “D” when towing
a heavy trailer to prevent fluid overheating. A lower gear should beused. n Parking on a grade
Always block the wheels under both vehicle and trailer when parking.
Apply the parking brake firmly. You should not park on a hill or slope.But if parking on a hill or slope cannot be avoided, you should takethe following steps:
1. Apply the brakes and hold the pedal down.
2. Have someone place wheel blocks under both the vehicle and
trailer wheels.
3. When the wheel blocks are in place, release the regular brakes
slowly until the blocks absorb the load.
4. Apply the regular brakes and then apply the parking brake; slowly

Engine overheating
WARNING
Never attempt to remove the radiator cap until the engine has been shut off and has fully cooled down. When the engine is hot,the coolant is under pressure. Removing the cap while the engineis still hot could release a spray of boiling hot coolant, which
could burn you very seriously.
If the engine overheats, safely pull off the road and stop the vehicle in asafe place. If steam is coming from the engine compartment
Turn the engine off and get everyone away from the vehicle until itcools down. If no steam is coming from the engine compartment
1. Keep the engine running at idling speed.
2. Open the hood to ventilate the engine compartment.
Confirm that the cooling fan is turning. If the fan is not turning, im-
mediately turn the engine off and contact your authorized dealer for
repair.
3. After the engine coolant temperature has dropped, turn off the en-gine.
If the temperature gauge stays at the overheated zone, turn the en-
gine off.
4. After the engine has fully cooled down, check the coolant level in
the reserve tank.If the coolant level is below the “MIN” mark, add coolant up to the
“MAX” mark.
5. If there is no coolant in the reserve tank, add coolant to the reserve
tank. Then remove the radiator cap and fill the radiator with coolant.
If you remove the radiator cap from a hot radiator, first wrap a thick
cloth around the radiator cap, then turn the cap counterclockwise
slowly without pressing down until it stops. Release the pressure from
