Features of your vehicle
Immobilizer system (if equipped)Your vehicle is equipped with an elec-
tronic engine immobilizer system to
reduce the risk of unauthorized vehicle
use.
Your immobilizer system is comprised of
a small transponder in the ignition key
and electronic devices inside the vehicle.
With the immobilizer system, whenever
you insert your ignition key into the igni-
tion switch and turn it to ON, it checks
and determines and verifies if the ignition
key is valid.
If the key is determined to be valid, the
engine will start.
If the key is determined to be invalid, the
engine will not start.To activate the immobilizer system:Turn the ignition key to the OFF position.
The immobilizer system activates auto-
matically. Without a valid ignition key for
your vehicle, the engine will not start.To deactivate the immobilizer sys-tem:Insert the ignition key into the key cylin-
der and turn it to the ON position.
✽ ✽ NOTICEWhen starting the engine, do not use the
key with other immobilizer keys around.
Otherwise the engine may not start or
may stop soon after it starts. Keep each
key separate in order to avoid a starting
malfunction.
✽ ✽NOTICEIf you need additional keys or lose your
keys, consult an authorized HYUNDAI
dealer.
CAUTION
The transponder in your ignition
key is an important part of the immobilizer system. It is designedto give years of trouble-free service, however you should avoid expo-sure to moisture, static electricity and rough handling. Immobilizersystem malfunction could occur.
WARNING
In order to prevent theft of your
vehicle, do not leave spare keys
anywhere in your vehicle. Your
Immobilizer password is a cus-
tomer unique password and should
be kept confidential. Do not leave
this number anywhere in your vehi-
cle.
CAUTION
Do not change, alter or adjust the immobilizer system because itcould cause the immobilizer sys- tem to malfunction and should onlybe serviced by an authorized HYUNDAI dealer.
Malfunctions caused by improperalterations, adjustments or modifi-cations to the immobilizer system are not covered by your vehiclemanufacturer warranty.

Integrated HomeLink
®Wireless Control
System
The HomeLink
®Wireless Control System
provides a convenient way to replace up
to three hand-held radio-frequency (RF)
transmitters with a single built-in device.
This innovative feature will learn the
radio frequency codes of most current
transmitters to operate devices such as
gate operators, garage door openers,
entry door locks, security systems, even
home lighting. Both standard and rolling
code-equipped transmitters can be pro-
grammed by following the outlined proce-
dures. Additional HomeLink
®information
can be found at: www.homelink.com or
by calling 1-800-355-3515. Retain the original transmitter of the RF
device you are programming for use in
other vehicles as well as for future
HomeLink
®programming. It is also sug-
gested that upon the sale of the vehicle,
the programmed HomeLink
®buttons be
erased for security purposes.
CAUTION
Before programming HomeLink
®to
a garage door opener or gate oper- ator, make sure that people andobjects are out of the way of thedevice to prevent potential harm or damage. Do not use HomeLink®
with any garage door opener thatlacks the safety stop and reversefeatures required by U.S. federal safety standards (this includes anygarage door opener model manu- factured before April 1, 1982). Agarage door that cannot detect anobject - signaling the door to stop and reverse - does not meet currentU.S. federal safety standards. Usinga garage door opener without these features increases the risk of seri-ous injury or death.

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.

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
