2003 NISSAN ALTIMA maintenance

Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front and rear disc-type brakes self-adjust
every time the brake pedal is applied.
WARNING
See a NISSAN dealer for a brake system
check if the brake pedal height does not
return to normal.
Brake pad wear indicators
The disc brake pads on your vehicle have audible
wear indicators. When a brake pad requires re-
placement, a high pitched scraping or screech-
ing sound will be heard when the vehicle is in
motion. The noise will be heard whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear indicator
sound is heard.
Under some driving or climate conditions, occa-
sional brake squeak, squeal or other noise may
be heard. Occasional brake noise during light to
moderate stops is normal and does not affect the
function or performance of the brake system.
Proper brake inspection intervals should
be followed.For more information regarding
brake inspections, see the appropriate mainte-nance schedule information in the “NISSAN Ser-
vice and Maintenance Guide”.
BRAKE BOOSTER
Check the brake booster function as follows:
1. With the engine off, press and release the
brake pedal several times. When brake
pedal movement (distance of travel) remains
the same from one pedal application to the
next, continue on to the next step.
2. While depressing the brake pedal, start the
engine. The pedal height should drop a little.
3. With the brake pedal depressed, stop the
engine. Keep the pedal depressed for about
30 seconds. The pedal height should not
change.
4. Run the engine for one minute without de-
pressing the brake pedal, then turn it off.
Depress the brake pedal several times. The
pedal travel distance will decrease gradually
with each depression as the vacuum is re-
leased from the booster.
If the brakes do not operate properly, have the
brakes checked by a NISSAN dealer.

HEADLIGHTS
Replacing the xenon headlight bulb
WARNING
cHIGH VOLTAGE
When xenon headlights are on, they pro-
duce a high voltage. To prevent an electric
shock, never attempt to modify or disas-
semble. Always have your xenon head-
lights replaced at a NISSAN dealer. For
additional information, see “Headlight
and turn signal switch” in the “Instru-
ments and controls” section.
Replacing the halogen headlight bulb
The headlight is a semi-sealed beam type which
uses a replaceable headlight (halogen) bulb. Be-
cause the headlight assembly must be removed
from the vehicle for bulb replacement, see your
NISSAN dealer.
CAUTION
cAiming is not necessary after replacing
the bulb. When aiming adjustment is
necessary, contact a NISSAN dealer.cDo not leave the headlight assembly
open without a bulb installed for a long
period of time. Dust, moisture, smoke,
etc. entering the headlight body may
affect bulb performance. Remove the
bulb from the headlight assembly just
before a replacement bulb is installed.
cOnly touch the plastic base when han-
dling the bulb. Never touch the glass
envelope. Touching the glass could sig-
nificantly affect bulb life and/or head-
light performance.
cHigh pressure halogen gas is sealed
inside the halogen bulb. The bulb may
break if the glass envelope is scratched
or the bulb is dropped.
cUse the same number and wattage as
originally installed:
