You need a helper to check the brake pedal
clearance. With the engine running, have your
helper press down on the brake pedal several
times and then hold it down with a force of about
110 lbs (50 kg, 490 N). The brake pedal clear-
ance is the distance from the top surface of the
brake pedal to the asphalt sheeting under the
floor mat.
If the brake pedal clearance is not within the
limits specified in the illustration, have it in-
spected by your Hyundai dealer and adjusted
or repaired if necessary.

Replacing Accessory Fuse
The fuse box for the lights and other electrical
accessories will be found in the backside of multi
box located in the left side of driver. Inside the box
you will find a list showing the circuits protected
by each fuse.
If any of your car's lights or other electrical
accessories stop working, a blown fuse could
be the reason. If the fuse has burned out, you
will see that the metal strip inside the fuse has
burned through. If you suspect a blown fuse,
follow this procedure:
1. Turn off the ignition and all other switches.
2. Open the fuse box and examine each fuse.
Remove each fuse by pulling it toward you
(a small "fuse puller" tool is contained in the
fuse box to simplify this operation).
3. Be sure to check all other fuses even if you
find one that appears to have burned out.

Drive belts should be checked periodically for
proper tension and adjusted if necessary. At the
same time, belts should be examined for cracks,
wear, fraying or other evidence of deterioration
and replaced if necessary.
Belt routing should also be checked to be sure
there is no interference between the belts and
other parts of the engine. After a belt is re-
placed, the new belt should be adjusted again
after two or three weeks to eliminate slack
resulting from initial stretching after use.A fusible link will melt if the electrical circuits
from the battery are ever overloaded, thus pre-
venting damage to the entire wiring harness.
(This could be caused by a short in the system
drawing too much current.) If this ever happens,
have a Hyundai dealer determine the cause,
repair the system and replace the fusible link.
The fusible links are located in a relay box for
easy inspection.

fuse of the same rating into place. The fuse
should be a snug fit. If it is not, have the fuse
clip repaired or replaced by a Hyundai dealer.

The Positive Crankcase Ventilation System is
employed to prevent air pollution caused by
blow-by gases being emitted from the crank-

the crankcase through the air intake hose.
Inside the crankcase, the fresh air mixes with
blow-by gases, which then pass through the
PCV valve and into the induction system.
