the conventional type of spark plugs.

3. With the foot brake pedal depressed, stop  
the engine. Keep the pedal depressed for  
about 30 seconds. The pedal height should  
not change.  
CHECKING FOOT BRAKE PEDAL  
Self-adjusting brakes  
Your vehicle is equipped with self-adjusting  
brakes. The disc-type brakes self-adjust every  
time the foot brake pedal is applied.  
4. Run the engine for  
1 minute without  
Brake pad wear warning  
depressing the foot brake pedal, then turn  
it off. Depress the foot brake pedal several  
times. The pedal travel distance will de-  
crease gradually with each depression as  
the vacuum is released from the booster.  
The disc brake pads have audible wear warn-  
ings. When a brake pad requires replacement, it  
will make a high pitched scraping sound when  
the vehicle is in motion. This scraping sound  
will first occur only when the brake pedal is  
depressed. After more wear of the brake pad,  
the sound will always be heard even if the  
brake pedal is not depressed. Have the brakes  
checked as soon as possible if the wear  
warning sound is heard.  
If the brakes do not operate properly, have the  
brakes checked by a NISSAN dealer.

WARNING:  
Under some driving or climate conditions,  
occasional brake squeaks, squeals or other  
noises 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.  
See  
a NISSAN dealer for a brake system  
check if the foot brake pedal height does  
not return to normal.  
With the engine running, check the distance  
between the upper surface of the pedal and  
the metal floor. If it is out the range listed, see a  
NISSAN dealer.  
Proper brake inspection intervals should be  
followed. For additional information, see  
separate maintenance booklet.

remains the same from one pedal applica-  
tion to the next, continue on to the next  
step.
