Air bag warning light(if equipped)
This warning light will illuminate for
approximately 6 seconds each time you
turn the ignition switch to the ON posi-tion. This light also comes on when the

not working properly. If the SRS air bag
warning light does not come on, or
continuously remains on after operating
for about 6 seconds when you turned the
ignition switch to the ON position or start-
ed the engine, or if it comes on whilst
driving, have the SRS inspected by an

is turned ON and goes off in approxi-
mately 3 seconds if the system is operat-
ing normally.
If the ABS warning light remains on,
comes on whilst driving, or does not
come on when the ignition switch is
turned to the ON position, this indicates
that there may be a malfunction with the
ABS.

by an authorised HYUNDAI dealer as
soon as possible. The normal braking
system will still be operational, but with-
out the assistance of the anti-lock brakesystem. Electronic brake

Parking brake & brakefluid warning light
Parking brake warning
This light is illuminated when the parking
brake is applied with the ignition switch in
the START or ON position. The warning
light should go off when the parking
brake is released whilst the engine is
running. 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 autho-
rised HYUNDAI dealer for a brake sys-
tem inspection and necessary repairs.
Your vehicle is equipped with dual-diago-
nal braking systems. This means you still
have braking on two wheels even if one
of the dual systems should fail. With only
one of the dual systems working, more
than normal pedal travel and greaterpedal 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 working. If the brakes fail
whilst 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.
CAUTION
If the oil pressure warning light stays on whilst the engine is run-
ning, serious engine damage mayresult. The oil pressure warninglight comes on whenever there is insufficient oil pressure. In normal
operation, it should come on whenthe ignition switch is turned on,then go out when the engine is
started. If the oil pressure warninglight stays on whilst the engine isrunning, there is a serious malfunc-tion.
If this happens, stop the car assoon as it is safe to do so, turn off the engine and check the oil level. Ifthe oil level is low, fill the engine oilto the proper level and start the
engine again. If the light stays onwith the engine running, turn theengine off immediately. In any instance where the oil light stays on
when the engine is running, theengine should be checked by an authorised HYUNDAI dealer beforethe car is driven again.

not operate properly when:
1. Moisture is frozen to the sensor. (It will
operate normally when the moisture has been cleared.)
2. The sensor is covered with foreign matter, such as snow or water, or the
sensor cover is blocked. (It will operate
normally when the material is removed
or the sensor is no longer blocked.)
3. Driving on uneven road surfaces (unpaved roads, gravel, bumps, gradi-ent).
4. Objects generating excessive noise (vehicle horns, loud motorcycle
engines, or truck air brakes) are within
range of the sensor.
5. Heavy rain or water spray exists.
6. Wireless transmitters or mobile phones are within range of the sensor.
7. The sensor is covered with snow.

1. The sensor is stained with foreign mat-
ter such as snow or water. (The sens-
ing range will return to normal when
removed.)
2. Outside air temperature is extremely hot or cold.
The following objects may not be rec-
ognized by the sensor:
1. Sharp or slim objects such as ropes, chains or small poles.
2. Objects which tend to absorb the sen- sor frequency such as clothes, spongy
material or snow.
3. Undetectable objects smaller than 1 m (40 in.) in height and narrower than 14
cm (6 in.) in diameter. Rear parking assist system pre- cautions

sor, or it may sense an incorrect dis-
tance. Use caution.
