2002 SUBARU IMPREZA warning

Maintenance and service

CAUTION
If you continue to drive despite the scraping noise from the audible brake pad wear indica-
tor, it will result in the need for costly brake rotor repair or replacement.
Breaking-in of new brake pads and linings
When replacing the brake pad or lining, use only
genuine SUBARU parts. After replacement, the new
parts must be broken in as follows:
Brake pad and lining
While maintaining a speed of 30 to 40 mph (50 to 65
km/h), step on the brake pedal lightly. Repeat this
five or more times.
Parking brake lining
1. Drive the vehicle at a speed of about 22 mph (35km/h).
2. With the parking brake release button pushed in,
pull the parking brake lever SLOWLY and GENTLY.
(Pulling with a force of approximately 33 lb [147 N,15 kg].)
3. Drive the vehicle for about 220 yards (200 me- ters) in this condition. 4. Wait 5 to 10 minutes for the parking brake to cool
down. Repeat this procedure.
5. Check the parking brake stroke. If the parking
brake stroke is out of the specified range, adjust it
by turning the adjusting nut located on the parking
brake lever.
Parking brake stroke: 7 – 8 notches / 44 lb (196 N, 20 kg)
WARNING
A safe location and situation should be se- lected for break-in driving.
CAUTION
Pulling the parking brake lever too forcefully
may cause the rear wheels to lock. To avoid
this, be certain to pull the lever up slowly and
gently.

Driving even a short distance warms up the tires
and increases the tire pressures. Also, the tire pres-
sures are affected by the ambient temperature. It is
best to check tire pressure outdoors before drivingthe vehicle.
When a tire becomes warm, the air inside it ex-
pands, causing the tire pressure to increase. Be
careful not to mistakenly release air from a warm tire
to reduce its pressure. NOTE The air pressure in a tire increases by approxi-
mately 4.3 psi (30 kPa, 0.3 kg/cm 2
) when the tire
becomes warm. The tires are considered cold when the vehicle
has been parked for at least three hours or hasbeen driven less than one mile (1.6 km).
WARNING
Do not let air out of warm tires to adjust
pressrue. Doing so will result in low tire pres-sure.
Incorrect tire pressures detract from controllability
and ride comfort, and they cause the tires to wear
abnormally.
Correct tire pressure (tread worn evenly)
HGB033AA
Roadholding is good, and steering is responsive.
Rolling resistance is low, so fuel consumption is
also lower.

Maintenance and service
11-40
Abnormally low tire pressure (tread worn at
shoulders)
HGB024AA
Rolling resistance is high, so fuel consumption is
also higher.
Abnormally high tire pressure (tread worn in
center)
HGB025AA
Ride comfort is poor. Also, the tire magnifies the
effects of road-surface bumps and dips, possibly
resulting in vehicle damage.
If the tire placard shows tire pressures for the ve-
hicle when fully loaded and for the vehicle when
towing a trailer, adjust the tire pressures to the val-
ues that match current loading conditions.
WARNING
Driving at high speeds with excessively low tire pressures can cause the tires to deform
severely and to rapidly become hot. A sharp

WARNING
When a tire’s tread wear indicator becomes
visible, the tire is worn beyond the acceptable
limit and must be replaced immediately. With atire in this condition, driving at high speeds in wet weather can cause the vehicle to hydro- plane. The resulting loss of vehicle controlcan lead to an accident.
NOTE
For safety, inspect tire tread regularly and re-
place the tires before their tread wear indicators
become visible.
Tire rotation
OM-H0230
Tire wear varies from wheel to wheel. To maximize
the life of each tire and ensure that the tires wear
uniformly, it is best to rotate the tires every 7,500
miles (12,500 km). Rotating the tires involves switch-
ing the front and rear tires on the right-hand side of
the vehicle and similarly switching the front and rear
tires on the left-hand side of the vehicle. (Each tiremust be kept on its original side of the vehicle.)
Replace any damaged or unevenly worn tire at the
time of rotation. After tire rotation, adjust the tire
pressures and make sure the wheel nuts are cor-
rectly tightened.
After driving approximately 600 miles (1,000 km),

check the wheel nuts again and retighten any nut that has become loose. Tire replacement
The wheels and tires are important and integral
parts of your vehicle ’s design; they cannot be
changed arbitrarily. The tires fitted as standard
equipment are optimally matched to the characteris-
tics of the vehicle and were selected to give the best
possible combination of running performance, ride
comfort, and service life. It is essential for every tireto have a size and construction matching those
shown on the tire placard and to have a speed sym-
bol and load index matching those shown on the tire
placard.
Using tires of a non-specified size detracts from
controllability, ride comfort, braking performance,
speedometer accuracy and odometer accuracy. It
also creates incorrect body-to-tire clearances and
inappropriately changes the vehicle ’s ground clear-
ance.
All four tires must be the same in terms of manufac-
turer, brand (tread pattern), construction, and size.
You are advised to replace the tires with new ones
that are identical to those fitted as standard equip- ment. For safe vehicle operation, SUBARU recommends
replacing all four tires at the same time. NOTE Unidirectional tires: Some tires have a specified direction of rotation. A tire of this type has an ar-
row or other mark on its side wall to indicate the direction of rotation. Install it in a manner the direction of rotation is correct when the vehicleis driven forward.
WARNING

All four tires must be the same in terms of
manufacturer, brand (tread pattern), construc-
tion, degree of wear, speed symbol, load indexand size. Mixing tires of different types, sizesor degrees of wear can result in damage to ve-
hicle’ s power train. Use of different types or
sized of tires can also dangerously reduce
controllability and braking performance andcan lead to an accident. Use only radial tires. Do not use radial tires
together with belted bias tires and/or bias-ply tires. Doing so can dangerously reduce con-
trollability, resulting in an accident.

Wheel replacement
When replacing wheels due, for example, to dam-
age, make sure the replacement wheels match the
specifications of the wheels that are fitted as stan-
dard equipment. Replacement wheels are available
from SUBARU dealers.
WARNING
Use only those wheels that are specified for your vehicle. Wheels not meeting specifica-tions could interfere with brake caliper opera-tion and may cause the tires to rub against the wheel well housing during turns. The resulting loss of vehicle control could lead to an acci-dent.
Wheel covers
Removing the wheel cover
HGA012BA
Insert the wheel cover remover into the notch pro-
vided, and pry the wheel cover off.

Battery
WARNING
Before beginning work on or near any bat-
tery, be sure to extinguish all cigarettes,
matches, and lighters. Never expose a batteryto an open flame or electric sparks. Batteriesgive off a gas which is highly flammable andexplosive. For safety, in case an explosion does occur,
wear eye protection or shield your eyes when
working near any battery. Never lean over a
battery. Do not let battery fluid contact eyes, skin,
fabrics, or paint because battery fluid is a cor- rosive acid. If battery fluid gets on your skin or in your eyes, immediately flush the area
with water thoroughly. Seek medical help im-
mediately if acid has entered the eyes.If battery fluid is accidentally swallowed,
immediately drink a large amount of milk or
water, and seek medical attention immediately. To lessen the risk of sparks, remove rings,
metal watchbands, and other metal jewelry.
Never allow metal tools to contact the positive because a short circuit will result.
Keep everyone including children away
from the battery. Charge the battery in a well-ventilated area.
Battery posts, terminals and related acces-
sories contain lead and lead compounds,
chemicals known to the State of California to
cause cancer and reproductive harm.
Wash
hands after handling.
CAUTION
Never use more than 10 amperes when charg- ing the battery because it will shorten batterylife.
