WARNING
 Before closing the hood, ensurethat all obstructions are removed
from the hood opening. Closing
the hood with an obstruction
present in the hood opening may
result in property damage or
severe personal injury.
 Do not leave gloves, rags or any other combustible material in the
engine compartment. Doing so
may cause a heat-induced fire.

before driving away. If it is not
latched, the hood could open
while the vehicle is being driven,
causing a total loss of visibility,
which might result in an accident.
 Do not move the vehicle with the hood raised. The view will be
blocked and the hood could fall
or be damaged.

4Anti-lock brake system
(ABS) warning light This light illuminates if the ignition switch
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 while 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.
If this occurs, have your vehicle checked
by an authorized HYUNDAI dealer as
soon as possible. The normal braking
system will still be operational, but with-
out the assistance of the anti-lock brake
system. Electronic brake force distri-
bution (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.
✽ ✽

Parking brake & brake fluid
warning lightParking 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 the vehicle towed to any author-
ized HYUNDAI dealer for a brake sys-
tem inspection and necessary 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 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 switch
is in the ON position.
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 authorized HYUNDAI
dealer.
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 is insufficient oil pressure. In normaloperation, 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 while the engine isrunning, 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. Ifthe oil level is low, fill the engine oil to the proper level and start theengine again. If the light stays onwith the engine running, turn theengine off immediately. In any instance where the oil light stays onwhen the engine is running, theengine should be checked by an authorized HYUNDAI dealer beforethe car is driven again.

Features of your vehicle
Low brake vacuum pressure warning
(2.0 TGDI engine only, if equipped)
If the warning light remains on, it may
indicate that the brake vacuum pump has
any problem. Therefore you should avoid
high speed driving or sudden stop, and
you should depress the brake pedal
deeper and harder than usual in braking.
Make sure to have the brake system
checked and repaired by an authorized
HYUNDAI dealer.
Low tire pressure telltale The low tire pressure telltale illuminates
when one or more of your tires is signifi-
cantly underinflated.
The low tire pressure telltale will illumi-
nate after it blinks for approximately one
minute when there is a problem 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 chapter
6.
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.
WARNING
- Safe stopping
 The TPMS cannot alert you to
severe and sudden tire damage
caused by external factors.
 If you feel any vehicle instability, immediately take your foot off the
accelerator, apply the brakes
gradually and with light force,
and slowly move to a safe posi-
tion off the road.
WARNING
 Continuous braking while drivingon steep or long downhill may
cause to descend the vacuum
level in brake booster for a time
and turn on the warning light. In
this case, shift down the trans-
mission. If the warning light illu-
minate continuously, stop the
vehicle in the safe location and
wait until the warning light goes
off.
 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.
