WARNING
Pre-tensioners are designed to operate only one time. After acti-
vation, pre-tensioner seat belts
must be replaced. All seat belts,
of any type, should always be
replaced after they have been
worn during a collision.
The pre-tensioner seat belt assembly mechanisms become
hot during activation. Do not
touch the pre-tensioner seat belt
assemblies for several minutes
after they have been activated.
Do not attempt to inspect or replace the pre-tensioner seat
belts yourself. This must be done
by an authorised Hyundai dealer.
Do not strike the pre-tensioner seat belt assemblies.
Do not attempt to service or repair the pre-tensioner seat belt
system in any manner.
(Continued)(Continued)
Improper handling of the pre-ten-sioner seat belt assemblies, and failure to heed the warnings not
to strike, modify, inspect, replace,
service or repair the pre-tension-
er seat belt assemblies may lead
to improper operation or inadver-
tent activation and serious injury.
Always wear the seat belts when driving or riding in a motor vehi-
cle.
If the vehicle or pre-tensioner seat belt must be discarded, con-tact an authorised Hyundai deal-
er.CAUTION
Because the sensor that activates
the SRS air bag is connected withthe pre-tensioner seat belt, the SRS air bag warning light on the
instrument panel will illuminatefor approximately 6 seconds afterthe ignition key has been turned to the "ON" position, and then it
should turn off.
If the pre-tensioner seat belt is not working properly, this warninglight will illuminate even if there is
no malfunction of the SRS air bag.If the SRS air bag warning lightdoes not illuminate when the igni- tion key is turned to "ON", or if it
remains illuminated after illumi-nating for approximately 6 sec- onds, or if it illuminates while thevehicle is being driven, please
have an authorised Hyundai deal-er inspect the pre-tensioner seat belt or SRS air bag system assoon as possible.

SRS Care
The SRS is virtually maintenance-free
and so there are no parts you can safely
service by yourself. If the SRS air bag
warning light does not illuminate, or con-
tinuously remains on, have your vehicle
immediately inspected by an authorised
Hyundai dealer.
Any work on the SRS system, such as
removing, installing, repairing, or any
work on the steering wheel must be per-
formed by an authorised Hyundai dealer.Improper handling of the SRS system
may result in serious personal injury.
WARNING
Do not install a child restraint system in the front passenger
seat position. A child restraint
system must never be placed in
the front seat. The infant or child
could be severely injured by an
air bag deployment in case of anaccident.
Modification to SRS components or wiring, including the addition
of any kind of badges to the pad
covers or modifications to the
body structure, can adversely
affect SRS performance and lead
to possible injury.
For cleaning the air bag pad cov- ers, use only a soft, dry cloth or
one which has been moistened
with plain water. Solvents or
cleaners could adversely affect
the air bag covers and proper
deployment of the system.

No objects should be placed over
or near the air bag modules on the
steering wheel, instrument panel,
and the front passenger's panel
above the glove box, because any
such object could cause harm if the
vehicle is in a crash severe enough
to cause the air bags to inflate.
(Continued)
(Continued)
If the air bags inflate, they must be replaced by an authorised
Hyundai dealer.
Do not tamper with or disconnect SRS wiring, or other components
of the SRS system. Doing so
could result in injury, due to acci-
dental inflation of the air bags or
by rendering the SRS inopera-
tive.
If components of the air bag sys- tem must be discarded, or if the
vehicle must be scrapped, certain
safety precautions must be
observed. An authorised Hyundai
dealer knows these precautions
and can give you the necessary
information. Failure to follow
these precautions and proce-dures could increase the risk of
personal injury.
If your car was flooded and has soaked carpeting or water on
flooring, you shouldn't try to start
the engine; have the car towed to
an authorised Hyundai dealer.

Features of your vehicle
The ECU checks the signal whether 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 deactivate the immobiliser sys-tem:
Insert the ignition key into the key cylin-
der and turn it to the ON position.
To activate the immobiliser system:
Turn the ignition key to the OFF position.
The immobiliser system activates auto-
matically. Without a valid ignition key for
your vehicle, the engine will not start.
✽✽ NOTICE
When starting the engine, do not use the
key with other immobiliser keys around.Otherwise the engine may not start or
may stop soon after it starts. To avoid
malfunction of the immobiliser system,always keep ignition key on separatekey chain / ring.
✽
✽ NOTICE
If you need additional keys or lose your keys, consult an authorised Hyundai
dealer.
CAUTION
The transponder in your ignition key is an important part of the immobiliser system. It is designed to give years of trouble-free service,
however you should avoid expo- sure to moisture, static electricityand rough handling. Immobiliser system malfunction could occur.
CAUTION
Do not change, alter or adjust theimmobiliser system because it
could cause the immobiliser sys- tem to malfunction and should onlybe serviced by an authorisedHyundai dealer.
Malfunctions caused by improperalterations, adjustments or modifi- cations to the immobiliser systemare not covered by your vehicle manufacturer warranty.
WARNING
In order to prevent theft of your
vehicle, do not leave spare keys
anywhere in your vehicle.
CAUTION

Features of your vehicle
Checking the amount of air con-
ditioner refrigerant and compres-sor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a bad influ-ence on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorised Hyundai dealer.
✽✽NOTICE
When the performance of the air condi-
tioning system is reduced it is important
that the correct type and amount of oil
and refrigerant is used. Otherwise,
damage to the compressor and abnor-
mal system operation may occur.
CAUTION
The air conditioning system should be serviced by an authorised
Hyundai dealer. Improper servicemay cause serious injury to the per-son performing the service.

Driving your vehicle
R (Reverse)
Use this position to drive the vehicle
backward.N (Neutral)
The wheels and transaxle are not locked.
The vehicle will roll freely even on the
slightest incline unless the hand brake or
service brakes are applied. D (Drive)
This is the normal forward driving posi-
tion. The transaxle will automatically shift
through a 4-gear sequence, providing the
best fuel economy and power.
For extra power when passing another
vehicle or climbing grades, depress the
accelerator fully, at which time the
transaxle will automatically downshift to
the next lower gear.
✽✽
NOTICE
Always come to a complete stop before shifting into D (Drive).
WARNING
Shifting into P (Park) while the vehicle is in motion will cause the
drive wheels to lock which will
cause you to lose control of the
vehicle.
Do not use the P (Park) position in place of the hand brake.
Always make sure the shift lever
is latched in the P (Park) position
and set the hand brake fully.
Before leaving the driver’s seat, always make sure the shift lever
is in the P (Park) position. Set the
hand brake fully, shut the engine
off and take the key with you.
Unexpected and sudden vehicle
movement can occur if you do
not follow these precautions in
the order specified.
Never leave a child unattended in a vehicle.
CAUTION
The transaxle may be damaged if
you shift into P (Park) while the
vehicle is in motion.
CAUTION
Always come to a complete stopbefore shifting into or out of R
(Reverse); you may damage thetransaxle if you shift into R while the vehicle is in motion, except asexplained in “Rocking the Vehicle”,
in this manual.

Good driving practices
Never move the gear selector lever
from P (Park) or N (Neutral) to any
other position with the acceleratorpedal depressed.
Never move the gear selector lever into "P" when the vehicle is in motion.
Be sure the car is completely stopped before you attempt to shift into R
(Reverse).
Never take the car out of gear and coast down a hill. This may be
extremely hazardous. Always leave the
car in gear when moving.
Do not "ride" the brakes. This can cause them to overheat and malfunc-
tion. Instead, when you are driving
down a long hill, slow down and shift to
a lower gear. When you do this, engine
braking will help slow the car.
Slow down before shifting to a lower gear. Otherwise, the lower gear maynot be engaged.
Always use the hand brake. Do not depend on placing the transaxle in P
(Park) to keep the car from moving.
Exercise extreme caution when driving on a slippery surface. Be especially
careful when braking, accelerating or
shifting gears. On a slippery surface,
an abrupt change in vehicle speed can
cause the drive wheels to lose traction
and the vehicle to go out of control. Optimum vehicle performance and
economy is obtained by smoothly
depressing and releasing the accelera-tor pedal.
Moving up a steep grade from a stand-
ing start
To move up a steep grade from a stand-
ing start, depress the brake pedal, shift
the shift lever to D (Drive). Select the
appropriate gear depending on load
weight and steepness of the grade, and
release the hand brake. Depress the
accelerator gradually while releasing the
service brakes.
When accelerating from a stop on a
steep hill, the vehicle may have a ten-
dency to roll backwards. Shifting the
shift lever into 2 (Second Gear) will
help prevent the vehicle from rolling
backwards.
WARNING
Always buckle-up! In a collision, an unbelted occupant is signifi-
cantly more likely to be seriously
injured or killed than a properlybelted occupant.
Avoid high speeds when corner- ing or turning.
Do not make quick steering wheel movements, such as sharp
lane changes or fast, sharp turns.
The risk of rollover is greatly increased if you lose control of
your vehicle at highway speeds.
Loss of control often occurs if two or more wheels drop off the
roadway and the driver over-
steers to reenter the roadway.
In the event your vehicle leaves the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
Never exceed posted speed lim- its.
CAUTION
If your vehicle becomes stuck in
snow, mud, sand, etc., then you mayattempt to rock the vehicle free by moving it forward and backward. Do
not attempt this procedure if people or objects are anywhere near thevehicle. During the rocking opera- tion the vehicle may suddenly move
forward of backward as it becomes unstuck, causing injury or damageto nearby people or objects.

Driving your vehicle
Power brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
In the event that the power-assisted
brakes lose power because of a stalled
engine or some other reason, you can
still stop your vehicle by applying greater
force to the brake pedal than you nor-
mally would. The stopping distance, how-
ever, will be longer.
When the engine is not running, the
reserve brake power is partially depleted
each time the brake pedal is applied. Do
not pump the brake pedal when the
power assist has been interrupted.
Pump the brake pedal only when neces-
sary to maintain steering control on slip-
pery surfaces.In the event of brake failure
If service brakes fail to operate while the
vehicle is in motion, you can make an
emergency stop with the hand brake. The
stopping distance, however, will be much
greater than normal.
BRAKE SYSTEM (Continued)
When descending a long or steep
hill, shift to a lower gear and
avoid continuous application of
the brakes. Continuous brakeapplication will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.
Wet brakes may result the vehicle not to slow down at the usual rateand pull it to one side when the
brakes are applied. Applying the
brakes lightly will indicate
whether they have been affected
in this way. Always test yourbrakes in this fashion after driv-
ing through deep water. To dry
the brakes, apply them lightly
while maintaining a safe forward
speed until brake performancereturns to normal.
WARNING - Hand brake
Applying the hand brake while the
vehicle is moving at normal speeds
can cause a sudden loss of control
of the vehicle. If you must use the
hand brake to stop the vehicle, use
great caution in applying the brake.
WARNING - Brakes
Do not drive with your foot rest- ing on the brake pedal. This will create abnormal high brake tem-
peratures, excessive brake lining
and pad wear, and increasedstopping distances.

Disc brakes wear indicator
Your vehicle has disc brakes.
When your brake pads are worn and new
pads are required, you will hear a high-
pitched warning sound from your front or
rear brakes. You may hear this sound
come and go or it may occur whenever
you depress the brake pedal.
Please remember that some driving con-
ditions or climates may cause a brake
squeal when you first apply (or lightly
apply) the brakes. This is normal and
does not indicate a problem with your
brakes.
Hand brake
Applying the hand brake
To engage the hand brake, first apply the
foot brake and then without pressing the
release button, pull the hand brake lever
up as far as possible. In addition it is rec-
ommended that when parking the vehicle
on a gradient, the shift lever should be
positioned in the appropriate low gear on
manual transaxle vehicles or in the P
(Park) position on automatic transaxle
vehicles.
WARNING- Brake wear
This brake wear warning sound
means your vehicle needs service.
If you ignore this audible warning,
you will eventually lose braking
performance, which could lead to aserious accident.
CAUTION
Always replace brake pads as com- plete front or rear axle sets.
CAUTION
To avoid costly brake repairs, do
not continue to drive with wornbrake pads.
OHD056005R
CAUTION
Driving with the hand brake applied will cause excessive brake pad and
brake rotor wear.
