Anti-lock brake system(ABS) warning light (if equipped)
This light illuminates if the ignition switch
is turned to 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 while driving, or does not
come on when the ignition switch is
turned to the ON position, this indicates
that there may be a problem with the
ABS.
If this occurs, have your vehicle checked
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 force distri-bution (EBD) system warninglight
If two warning lights illumi- nate at the same time while
driving, your vehicle may
have a malfunction with ABSand EBD system.
In this case, your ABS and regular brake
system may not work normally. Have the
vehicle checked by an authorised
HYUNDAI dealer as soon as possible.

Seat belt warning
Type A
As a reminder to the driver, the seat belt
warning light will blink for approximately
6 seconds each time you turn the ignition
switch ON regardless of belt fastening.
Type B
As a reminder to the driver, the seat belt
warning light will blink for approximately
6 seconds each time you turn the ignition
switch ON regardless of belt fastening.
If the driver’s seat belt is unfastened after
the ignition switch is ON, the seat belt
warning light blinks again for approxi-
mately 6 seconds.
If the driver's seat belt is not fastened
when the ignition switch is turned ON or
if it is unfastened after the ignition switch
is ON, the seat belt warning chime will
sound for approximately 6 seconds.
Once the seat belt has been refastened
the chime will no longer sound. (ifequipped)
WARNING
If the both ABS and Brake warning
lights are on and stay on, your vehi-
cle’s brake system will not work
normally. So you may experience
an unexpected and dangerous situ-
ation during sudden braking. In this
case, avoid high speed driving and
abrupt braking. Have your vehicle
checked by an authorised
HYUNDAI dealer as soon as possi-
ble.

Parking brake & brakefluid warning
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. 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 it towed to any authorised
HYUNDAI dealer for a brake system
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
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 switchis 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 warning
light comes on whenever there isinsufficient oil pressure. In normaloperation, it should come on whenthe ignition switch is turned on,
then go out when the engine isstarted. If the oil pressure warninglight stays on while the engine is running, there is a serious malfunc-
tion.
If this happens, stop the car assoon as it is safe to do so, turn offthe engine and check the oil level. If
the oil level is low, fill the engine oilto the proper level and start theengine again. If the light stays onwith the engine running, turn the
engine off immediately. In anyinstance where the oil light stays onwhen the engine is running, the engine should be checked by an
authorised HYUNDAI dealer beforethe car is driven again.
WARNING
Driving the vehicle with a warning
light on is dangerous. If the brake
warning light remains on, have the
brakes checked and repaired imme-
diately by an authorised HYUNDAI
dealer.

D170200AEN-EA Non-operational conditions of rear parking assist system
The rear parking assist system may
not operate properly when:
1. Moisture is frozen to the sensor. (It willoperate 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. Trailer towing The detecting range may decrease when:
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. D170300AEN Rear parking assist system pre- cautions
The rear parking assist system may
not sound sequentially depending on the speed and shapes of the objectsdetected.
The rear parking assist system may malfunction if the vehicle bumperheight or sensor installation has been
modified or damaged. Any non-factory
installed equipment or accessories
may also interfere with the sensor per-
formance.
The sensor may not recognize objects less than 40 cm (15 in.) from the sen-
sor, or it may sense an incorrect dis-
tance. Use caution.
When the sensor is frozen or stained with snow, dirt, or water, the sensor
may be inoperative until the stains are
removed using a soft cloth.
Do not push, scratch or strike the sen- sor. Sensor damage could occur.
