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.
CAUTION
Do not put metal accessories nearthe ignition switch.
Metal accessories may interrupt thetransponder signal and may pre- vent the engine from being started.

Features of your vehicle
Electric power steering (EPS)The power steering uses a motor to
assist you in steering the vehicle. If the
engine is off or if the power steering sys-
tem becomes inoperative, the vehicle
may still be steered, but it will require
increased steering effort.
The motor driven power steering is con-
trolled by a power steering control unit
which senses the steering wheel torque
and vehicle speed to command the
motor.
The steering becomes heavier as the
vehicle’s speed increases and becomes
lighter as the vehicle’s speed decreases
for optimum steering control.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power steer-
ing checked by an authorized HYUNDAI
dealer.
✽ ✽NOTICEThe following symptoms may occur dur-
ing normal vehicle operation:
• The EPS warning light does not illumi-
nate.
• The steering effort is high immediately after turning the ignition switch on.
This happens as the system performs
the EPS system diagnostics. When the
diagnostics is completed, the steering
wheel will return to its normal condi-
tion.
• A click noise may be heard from the EPS relay after the ignition switch is
turned to the ON or LOCK position.
• A motor noise may be heard when the vehicle is at a stop or at a low driving
speed.
• If the Electric Power Steering System does not operate normally, the warn-
ing light will illuminate on the instru-
ment cluster. The steering wheel may
become difficult to control or operate
abnormally. Take your vehicle to an
authorized HYUNDAI dealer and
have the vehicle checked as soon as
possible.
• When you operate the steering wheel in low temperature, abnormal noise
could occur. If temperature rises, the
noise will disappear. This is a normal
condition.
STEERING WHEEL
CAUTION
 If the Electric Power Steering
System does not operate normal-ly, the warning light will illuminate on the instrument cluster. Thesteering wheel may become diffi-cult to control or operate abnor- mally. Take your vehicle to anauthorized HYUNDAI dealer and have the vehicle checked as soonas possible.
 When you operate the steering wheel in low temperature, abnor-mal noise could occur. If tempera- ture rises, the noise will disap-pear. This is a normal condition.

4Tilt steering Tilt steering allows you to adjust the
steering wheel before you drive. You can
also raise it to give your legs more room
when you exit and enter the vehicle.
The steering wheel should be positioned
so that it is comfortable for you to drive,
while permitting you to see the instru-
ment panel warning lights and gauges.
To change the steering wheel angle, pull
down the lock release lever (1), adjust
the steering wheel to the desired angle
(2) and height (if equipped) (3), then pull
up the lock-release lever to lock the
steering wheel in place. Be sure to adjust
the steering wheel to the desired position
before driving.
HornTo sound the horn, press the horn sym-
bol on your steering wheel.
Check the horn regularly to be sure it
operates properly.✽ ✽NOTICETo sound the horn, press the area indi-
cated by the horn symbol on your steer-
ing wheel (see illustration). The horn
will operate only when this area is
pressed.

CAUTION
Do not strike the horn severely to
operate it, or hit it with your fist. Do not press on the horn with a sharp-pointed object.
WARNING
 Never adjust the angle of the steering wheel while driving. You
may lose steering control and
cause severe personal injury,
death or accidents.
 After adjusting, push the steering wheel both up and down to be
certain it is locked in position.

4To adjust the Zone setting:
1. Determine the desired Zone Number
based upon your current location on
the Zone Map.
2. Press and hold the button for 6 sec- onds, the current Zone Number will
appear on the display.
3. Pressing and holding the button again will cause the numbers to incre-
ment (Note: they will repeat …13, 14,
15, 1, 2, …). Releasing the button
when the desired Zone Number
appears on the display will set the new
Zone.
4. Within about 5 seconds the compass will start displaying a compass head-
ing again.
There are some conditions that can
cause changes to the vehicle magnets,
such as installing a ski rack or a CB
antenna. Body repair work on the vehicle
can also cause changes to the vehicle's
magnetic field. In these situations, the
compass will need to be re-calibrated to
quickly correct for these changes. To re-
calibrate the compass: 1. Press and hold the button for more
than 9 seconds. When the compass
memory is cleared a "C" will appear in
the display.
2. To calibrate the compass, drive the vehicle in 2 complete circles at less
than 5 mph (8 km/h).
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.
