2003 SUBARU LEGACY brake fluid

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.

8-10traction by starting the vehicle with the transmission in 2nd than 1st
(both for MT and AT).
Never equip your vehicle with tires larger than those specified in
this manual. Frequent driving of an AWD vehicle under hard-driving conditions
such as rough roads or off roads will necessitate more frequent re-
placement of engine oil, brake fluid and transmission oil than that spe-
cified 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 precautions such as those listedabove is not eligible for warranty coverage.

Operation during cold weather
Carry some emergency equipment, such as tire chains, a window
scraper, a bag of sand, flares, a small shovel, and jumper cables.
Check the battery and cables. Cold temperatures reduce battery ca-
pacity. The battery must be in good condition to provide enough pow-
er for cold winter starts.
Use an engine oil of proper grade and viscosity for cold weather.
Heavy summer oil will cause harder 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 antifreeze solution. Do
not use engine antifreeze or other substitutes because they may dam-age the paint of the vehicle. n
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 accelera-
tor 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 peri-
odically. n Parking in cold weather
WARNING
Snow can trap dangerous exhaust gases under your vehicle. Keep snow clear of the exhaust pipe and from around your
vehicle if you park the vehicle in snow with the engine running.
Do not use the parking brake when parking for long periods in cold
weather since it could freeze in that position. Instead, observe the fol-lowing:
1. Place the shift lever in “1” or “R” for manual transmission 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 damage to them.

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

10-2Exterior care
Washing
CAUTION
When washing the vehicle, the brakes may get wet. As a result,
the brake stopping distance will be longer. To dry the brakes, drive the vehicle at a safe speed while lightly pressing the brakepedal to heat up the brakes. Do not wash the engine compartment and areas adjacent to it.
If water enters the engine air intake, electrical parts or the power
steering fluid reservoir, it will cause engine trouble or faulty
power steering respectively.
The best way to preserve your vehicle ’s beauty is frequent washing.
Wash the vehicle at least once a month to avoid contamination by roadgrime.
Wash dirt off with a wet sponge and plenty of lukewarm or cold water. Do
not wash the vehicle with hot water and in direct sunlight.
Salt, chemicals, insects, tar, soot and bird droppings should be washed
off by using a light detergent, as required. If you use a light detergent,
make certain that it is a neutral detergent. Do not use strong soap or
chemical detergents. All cleaning agents should be promptly flushed
from the surface and not allowed to dry there. Rinse the vehicle thor-
oughly with plenty of lukewarm water. Wipe the remaining water off with a
chamois or soft cloth. NOTE When having your vehicle washed in an automatic car wash, make
sure beforehand that the car wash is of suitable type. If the vehicle
is equipped with a rear/roof spoiler, it may be damaged by car washbrushes or other equipment.

Always use the proper tools and make certain that they are
well maintained. Never get under the vehicle supported only by a jack. Always
use a safety stands to support the vehicle. Never keep the engine running in a poorly ventilated area,
such as a garage or other closed areas. Do not smoke or allow open flames around the fuel or battery.
This will cause a fire. Because the fuel system is under pressure, replacement of the
fuel filter should be performed only by your SUBARU dealer. Wear adequate eye protection to guard against getting oil or
fluids in your eyes. If something does get in your eyes, thorough-
ly wash them out with clean water. Do not tamper with the wiring of the SRS airbag system or
seatbelt pretensioner system, or attempt to take its connectorsapart, as that may activate the system or it can render it inopera-tive. The wiring and connectors of these systems are yellow for
easy identification. NEVER use a circuit tester for these wiring. If your SRS airbag or seatbelt pretensioner needs service, con-
sult your nearest SUBARU dealer. Before checking or servicing in the engine compart- ment
Always stop the engine and set the parking brake firmly to pre-
vent the vehicle from moving. Always let the engine cool down. Engine parts become very
hot when the engine is running and remain hot for some time af-ter the engine is stopped. Do not spill engine oil, engine coolant, brake fluid or any other
fluid on hot engine components. This may cause a fire. Always remove the key from the ignition switch. When the
ignition switch is in the “ON” position, the cooling fan may oper-
ate suddenly even when the engine is stopped.
