Anti-lock brake system
(ABS) warning light
This light illuminates if the ignition
switch is turned ON and goes off in
approximately 3 seconds if the system
is operating normally.
If the ABS warning light remains on,
comes on while driving, or does not
come on when the ignition switch is
turned to the ON position, this indi-
cates that there may be a malfunction
with the ABS.
If this occurs, have your vehicle
checked by an authorized HYUNDAI
dealer as soon as possible. The nor-
mal braking system will still be oper-
ational, but without the assistance of
the anti-lock brake system. If the ABS warning light turns on
while driving
1. Park the vehicle in a safe place
and turn off the engine.
2. Turn on the engine again.
3. If the warning light illuminates and turns off in approximately 3 sec-
onds, the system is operating nor-
mally.
If the warning light does not turn off,
have your vehicle checked by an
authorized HYUNDAI dealer as soon
as possible. Electronic brake force
distribution (EBD) system
warning light
If these two warning lights illuminate
at the same time while driving, your
vehicle may have a malfunction with
the ABS and EBD system.
In this case, your ABS and regular
brake system may not work normally.
Have the vehicle checked by an
authorized HYUNDAI dealer as soon
as possible.
WARNING
If the both ABS and brake warn-
ing lights are on and stay on,
your vehicle’s brake system will
not work normally during sudden
braking. In this case, avoid high
speed driving and abrupt brak-
ing. Have your vehicle checked
by an authorized HYUNDAI deal-
er as soon as possible.

ment panel show the direction indi-
cated by the turn signals. If the arrow

beam position or when the turn sig-
nal lever is pulled into the Flash-to-
Pass position.

Parking brake & brakefluid warning light
Parking brake warning
This light is illuminated when the
parking brake is applied with the igni-
tion switch in the START or ON posi-
tion. The warning light should go off
when the parking brake is released.
Low brake fluid level warning
If the warning light remains on, it may
indicate that the brake fluid level in
the reservoir is low.
If the warning light remains on:
1. Drive carefully to the nearest safe location and stop your vehicle.
2. With the engine stopped, check the brake fluid level immediately and
add fluid as required. Then check all
brake components for fluid leaks.
3. Do not drive the vehicle if leaks are found, the warning light remains on
or the brakes do not operate prop-
erly. Have the vehicle towed to any
authorized HYUNDAI dealer for a
brake system inspection and nec-
essary repairs. Your vehicle is equipped with a dual-
diagonal braking system. This means
you still have braking on two wheels
even if one of the brake circuits is
damaged or malfunctions. With only
one of the circuits working, more
than normal pedal travel and greater
pedal pressure are required to stop
the car. Also, the car will not stop in
as short a distance with only a por-
tion of the brake system working. If
the brakes fail while you are driving,
shift to a lower gear for additional
engine braking and stop the car as
soon as it is safe to do so.
To check bulb operation, check
whether the parking brake and brake
fluid warning light illuminates when the
ignition switch is in the ON position.
CAUTION
If the oil pressure warning light
stays on while the engine is run-ning, serious engine damage mayresult. The oil pressure warninglight comes on whenever there isinsufficient oil pressure. In nor-mal operation, it should come onwhen the ignition switch is turnedon, then go out when the engineis started. If the oil pressure warn-ing light stays on while theengine is running, there is a seri-ous malfunction.
If this happens, stop the car assoon as it is safe to do so, turnoff the engine and check the oillevel. If the oil level is low, fill theengine oil to the proper leveland start the engine again. If thelight stays on with the enginerunning, turn the engine offimmediately. In any instancewhere the oil light stays onwhen the engine is running, theengine should be checked by anauthorized HYUNDAI dealerbefore the car is driven again.
WARNING
Driving the vehicle with a warn-
ing light on is dangerous. If the
brake warning light remains on,
have the brakes checked and
repaired immediately by an
authorized HYUNDAI dealer.

✽ ✽NOTICE
If there is heavy accumulation of
snow or ice on the windshield,
defrost the windshield for about 10
minutes, or until the snow and/or ice
is removed before using the wind-
shield wipers to ensure proper oper-
ation.
✽ ✽NOTICE
• When you operate the wipers, if
your vehicle has a problem in any
part of the wiper operation sys-
tem, the wiper may operate in the
LO mode regardless of the wiper
switch position. In this case, have
your vehicle checked by an
authorized HYUNDAI dealer as
soon as possible.
• When the ignition key is removed, the wiper blade sometimes may
move slightly for reducing the
deterioration of the windshield
wipers.
Windshield washers
In the OFF position, pull the lever
gently toward you to spray washer
fluid on the windshield and to run the
wipers 1-3 cycles.
Use this function when the wind-
shield is dirty.
The spray and wiper operation will
continue until you release the lever.
If the washer does not work, check
the washer fluid level. If the fluid level
is not sufficient, you will need to add
appropriate non-abrasive windshield
washer fluid to the washer reservoir. The reservoir filler neck is located in
the front of the engine compartment
on the passenger side.

Driving your vehicle
WARNING- ENGINE EXHAUST CAN BE DANGEROUS!
Engine exhaust fumes can be extremely dangerous. If, at any time, you smell exhaust fumes inside the vehicle,
open the windows immediately.
• Do not inhale exhaust fumes. Exhaust fumes contain carbon monoxide, a colorless, odorless gas that can cause unconsciousness and death
by asphyxiation.
The exhaust system should be checked whenever the vehicle is raised to change the oil or for any other purpose.
If you hear a change in the sound of the exhaust or if you drive over something that strikes the under side of the
car, have the exhaust system checked as soon as possible by an authorized HYUNDAI dealer.
Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Never run the
engine in your garage any longer than it takes to start the engine and back the car out.
If it is necessary to idle the engine for a prolonged period with people inside the car, be sure to do so only in an
open area with the air intake set at "Fresh" and fan operating at one of the higher speeds so fresh air is drawn
into the interior.
If you must drive with the tailgate open because you are carrying objects that make this necessary:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at "Fresh", the air flow control at "Floor" or "Face" and the fan at one of the higher speeds.
To assure proper operation of the ventilation system, be sure the ventilation air intakes located just in front of the
windshield are kept clear of snow, ice, leaves or other obstructions.
