ANTI-LOCK BRAKE SYSTEM (ABS)C120A01FC-AATThe Anti-Lock Brake System (ABS) is designed
to prevent wheel lock-up during sudden braking
or on hazardous road surfaces. The ABS con-
trol module monitors the wheel speed and con-
trols the pressure applied to each brake. Thus,
in emergency situations or on slick roads, ABS
will increase vehicle control during braking.NOTE:o A click sound may be heard in the engine
compartment when the vehicle begins
to move after the engine is started. These
conditions are normal and indicate that
the anti-lock brake system (Electronic
Stability Control) is functioning prop-
erly.
o During ABS (ESC) operation, a pulsation
may be felt in the brake pedal when the
brakes are applied. Also, a noise may be
heard in the engine compartment while
braking. These conditions are normal
and indicate that the anti-lock brake
system (Electronic Stability Control Sys-
tem) is functioning properly.
Setting the driver's position1) Be sure the parking brake is engaged.
2) Move the accelerator and brake pedals to
the front most position by pushing the " "
portion of the switch.
3) Adjust the seat position and the steering
wheel angle properly.
4) Move the pedals toward you until you can
fully depress the brake pedal by pushing the
" " portion of the switch.
5) Depress the pedals a few times to get used
to the feel after adjusting.
WARNING:
o Adjust the pedals after parking the ve-
hicle on level ground. Never attempt to
adjust the pedals while the vehicle is
moving.
o Never adjust the pedals with your foot
on the accelerator pedal as this may
result in increasing the engine speed
and acceleration.
o Make sure that you can fully depress the
brake pedal before driving. Otherwise,
you may not be able to hold down the
brake pedal firmly in an emergency stop.
POWER ADJUSTABLE PEDALSC100A01NF-AAT(With Automatic Transaxle) (If Installed)To adjust the position of the accelerator and
brake pedals, turn the ignition key to the "ON"
position with the selector lever in the "P" position
and push the switch.
If you push the " " portion of the switch, the
pedals move rearward.
If you push the " " portion of the switch, the
pedals move forward.

pedal several times to reduce the vacuum in the
brake booster.
Then, using your hand, press down slowly on
the brake pedal until you feel a change in
resistance. This is the brake pedal free-play.
The free-play should be within the limits speci-
fied in the illustration above. If it is not, have it
inspected by your Hyundai dealer and adjusted
or repaired if necessary.

CHECKING BRAKE PEDAL
CLEARANCEG180A01A-AATYou 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

limits specified in the illustration, have it in-
spected by your Hyundai dealer and adjusted
or repaired if necessary.
