Features of your vehicle
Fuel gaugeThe fuel gauge indicates the approxi-
mate amount of fuel remaining in the fuel
tank.
The fuel tank capacity is given in
section 8.
The fuel gauge is supplement-
ed by a low fuel warning light, which will
illuminate when the fuel tank is near
empty.
On inclines or curves, the fuel gauge
pointer may fluctuate or the low fuel
warning light may come on earlier than
usual due to the movement of fuel in the
tank.
Trip computerThe trip computer is a microcomputer
controlled driver information system that
displays information related to driving on
the LCD screen when the ignition switch
is in the ON position. If the battery is dis-
connected, then all stored driving infor-
mation (except odometer) is reset.
WARNING
- Fuel gauge
Running out of fuel can expose
vehicle occupants to danger.
You must stop and obtain addition-
al fuel as soon as possible after the
warning light comes on or when the
gauge indicator comes close to the
E level.
CAUTION
Avoid driving with a very low fuel level. Running out of fuel could cause the engine to misfire, damag-ing the catalytic converter.

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.

to the ON position, the indicator will
illuminate until the engine is started.
However, when the smart key is not in
the vehicle, if the engine start/stop but-
ton is depressed, the indicator will blink
for a few minutes to indicate that you
will not be able to start the engine.  When the ignition switch is turned to
the ON position and the indicator turns
off after 2 seconds, the system may
need repair. Have the vehicle checked
by an authorized HYUNDAI dealer.

cator will blink and you will not be able
to start the engine. However, you may
still be able to start the engine by
inserting the smart key in the smart
key holder. If smart key system related
parts need repair, the indicator blinks.
Low fuel level warning lightThis warning light indicates the fuel tank
is nearly empty. When it comes on, you
should add fuel as soon as possible.
Driving with the fuel level warning light on
or with the fuel level below “E” can cause
the engine to misfire and damage the
catalytic converter.
Malfunction indicator light(MIL) (check engine light) This indicator light is part of the Engine
Control System which monitors various
emission control system components. If
this light illuminates while driving, it indi-
cates that a potential malfunction has
been detected somewhere in the emis-
sion control system.
This light will also illuminate when the
ignition switch is turned to the ON posi-
tion, and will go out in a few seconds
after the engine is started. If it illuminates
while driving, or does not illuminate when
the ignition switch is turned to the ON
position, take your vehicle to your near-
est authorized HYUNDAI dealer and

Do not continue driving with an overheat-
ed engine. If your vehicle overheats, refer
to “Overheating” in section 6.
ESC indicator (ElectronicStability Control) The ESC indicator will illuminate when
the ignition switch is turned ON, but
should go off after approximately 3 sec-
onds. When the ESC is on, it monitors
the driving conditions under normal driv-
ing conditions, the ESC light will remain
