Warnings and indicators
All warning lights are checked by
turning the ignition switch ON (do not
start the engine). Any light that does
not illuminate should be checked by
an authorized HYUNDAI dealer.
After starting the engine, check to
make sure that all warning lights are
off. If any are still on, this indicates a
situation that needs attention. When
releasing the parking brake, the
brake system warning light should go
off. The fuel warning light will stay on
if the fuel level is low.
Air bag warning light
This warning light will illuminate for
approximately 6 seconds each time
you turn the ignition switch to the ON
position.
This light also comes on when the
Supplemental Restraint System
(SRS) is not working properly. If the
SRS air bag warning light does
not come on, or continuously remains
on after operating for about 6 sec-
onds when you turned the ignition
switch to the ON position or started
the engine, or if it comes on while
driving, have the SRS inspected by
an authorized HYUNDAI dealer.
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 sys-
tem 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 malfunc-
tion 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.

463
Features of your vehicle
Turn signal indicator
The blinking green arrows on the
instrument panel show the direction
indicated by the turn signals. If the
arrow comes on but does not blink,
blinks more rapidly than normal, or
does not illuminate at all, a malfunc-
tion in the turn signal system is indi-
cated. Your dealer should be consult-
ed for repairs.
This indicator also blinks when the
hazard warning switch is turned on.
High beam indicator
This indicator illuminates when the
headlights are on and in the high
beam position or when the turn sig-
nal lever is pulled into the Flash-to-
Pass position.
Tail light indicator
(if equipped)
This indicator illuminates when the
tail lights are on.
Engine oil pressure
warning light
This warning light indicates the
engine oil pressure is low.
If the warning light illuminates while
driving:
1. Drive safely to the side of the road
and stop.
2. With the engine off, check the
engine oil level. If the level is low,
add oil as required.
If the warning light remains on after
adding oil or if oil is not available, call
an authorized HYUNDAI dealer.
CAUTION
If the engine is not stopped
immediately after the engine oil
pressure warning light is illumi-
nated, severe damage could
result.

Parking brake & brake
fluid 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
while an engine is running.
The parking brake warning chime will
sound to remind you that the parking
brake is applied when you are driving
above 6 mph (10 km/h). Always
release the parking brake before you
drive.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 properly. Have the vehicle
towed to any authorized HYUNDAI
dealer for a brake system inspec-
tion and necessary repairs.
CAUTION
If the oil pressure warning light
stays on while the engine is run-
ning, serious engine damage may
result. The oil pressure warning
light comes on whenever there is
insufficient oil pressure. In nor-
mal operation, it should come on
when the ignition switch is turned
on, then go out when the engine
is started. If the oil pressure warn-
ing light stays on while the
engine is running, there is a seri-
ous malfunction.
If this happens, stop the car as
soon as it is safe to do so, turn off
the engine and check the oil level.
If the oil level is low, fill the engine
oil to the proper level and start
the engine again. If the light stays
on with the engine running, turn
the engine off immediately. In any
instance where the oil light stays
on when the engine is running,
the engine should be checked by
an authorized HYUNDAI dealer
before the car is driven again.

Features of your vehicle
WARNING - Low tire pres-
sure
Significantly low tire pressure
makes the vehicle unstable and
can contribute to loss of vehicle
control and increased braking
distances.
Continued driving on tires with
low pressure will cause the tires
to overheat and fail.
Your vehicle is equipped with dual-
diagonal braking systems. This
means you still have braking on two
wheels even if one of the brake cir-
cuits 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 portion of the brake system work-
ing. If the brakes fail while you are
driving, shift to a lower gear for addi-
tional 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.Low tire pressure
telltale
The low tire pressure telltale illumi-
nates when one or more of your tires
is significantly underinflated.
Inflate your tires to the correct infla-
tion pressure.
The low tire pressure telltale will illu-
minate after it blinks for approximate-
ly one minute when there is a prob-
lem with the Tire Pressure
Monitoring System.
If this occurs, have the system
checked by an authorized HYUNDAI
dealer as soon as possible.
For details, refer to the TPMS on chap-
ter 6.
WARNING
Driving the vehicle with a warn-
ing light on is dangerous. If the
brake warning light remains on,
