✽✽NOTICE
Because the sensor that activates the
SRS air bag is connected with the pre-
tensioner seat belt, the SRS air bagwarning light on the instrument panel
will illuminate for approximately 6 sec-
onds after the ignition switch has beenturned to the "ON" position, and then itshould turn off.
C020300AUN Seat belt precautions
WARNING
All occupants of the vehicle must wear their seat belts at all times.
Seat belts and child restraintsreduce the risk of serious or fatal
injuries for all occupants in the
event of a collision or sudden stop.
Without a seat belt, occupants
could be shifted too close to a
deploying air bag, strike the interior
structure or be thrown from the
vehicle. Properly worn seat belts
greatly reduce these hazards.
Always follow the precautions
about seat belts, air bags and occu-
pant seat contained in this manual.
CAUTION
If the pre-tensioner seat belt is not working properly, this warning lightwill illuminate even if there is no malfunction of the SRS air bag. If
the SRS air bag warning light doesnot illuminate when the ignition key is turned to "ON", or if it remainsilluminated after illuminating for
approximately 6 seconds, or if it illuminates while the vehicle isbeing driven, please have an autho-rised HYUNDAI dealer inspect the
pre-tensioner seat belt or SRS air bag system as soon as possible.
(Continued)
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.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 deal-
er.
Do not strike the pre-tensioner seat belt assemblies.
Improper handling of the pre-ten- sioner seat belt assemblies, andfailure 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.

C041100AFD-EA 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 deal-
er. Improper handling of the SRS system
may result in serious personal injury.
WARNING
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 mustbe 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 pro-cedures 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.

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
It is important when servicing the air
conditioning system that the correct
type and amount of oil and refrigerant isused. Otherwise, damage to the com-
pressor and abnormal system operation
may occur.
WARNING
The air conditioning system should
be serviced by an authorised
HYUNDAI dealer. Improper service
may cause serious injury to the
person 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 parking brake
or service brakes are applied. D (Drive)
This is the normal forward driving posi-
tion. The transaxle will automatically shift
through a 4(5)-gear sequence, providing
the best fuel economy and power.
Bring the car to a complete stop before
shifting the selector to “D” position.
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.
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 parking brake.
Always make sure the shift lever
is latched in the P (Park) position
and set the parking brake fully.
Before leaving the driver’s seat, always make sure the shift lever
is in the P (Park) position. Set the
parking 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 precau-
tions 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 as
explained in “Rocking the Vehicle”,in this manual.

E060200AFD 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) or D (Drive).
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 parking 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.
E060203AUN-EA
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 parking 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 (if equipped).
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.
WARNING
If your vehicle becomes stuck in
snow, mud, sand, etc., then you
may attempt to rock the vehicle free
by moving it forward and backward.
Do not attempt this procedure if
people or objects are anywhere
near the vehicle. During the rocking
operation the vehicle may suddenly
move forward of backward as it
becomes unstuck, causing injury
or damage to nearby people orobjects.

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.E070101AUN
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 parking 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 impair the vehi- cle’s ability to slow down safely;
the vehicle may also pull to oneside when the brakes are applied.
Applying the brakes lightly will
indicate whether they have been
affected in this way. Always test
your brakes in this fashion after
driving through deep water. To
dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performancereturns to normal.
WARNING - Parking brake
Applying the parking brake while
the vehicle is moving at normal
speeds can cause a sudden loss of
control of the vehicle. If you mustuse the parking brake to stop the
vehicle, use great caution in apply-
ing 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 (if equipped). 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. Parking brake E070201AFD-EA
Applying the parking brake
To engage the parking brake, first apply
the foot brake and then without pressing
the release button, pull the parking brake
lever up as far as possible. In addition it
is recommended 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
To avoid costly brake repairs, do not continue to drive with wornbrake pads.
Always replace brake pads as complete front or rear axle sets.
CAUTION
Driving with the parking brakeapplied will cause excessive brake
pad and brake rotor wear.

Your vehicle's fuel economy depends
mainly on your style of driving, where you
drive and when you drive.
Each of these factors affects how many
kilometers (miles) you can get from a litre
(gallon) of fuel. To operate your vehicle
as economically as possible, use the fol-
lowing driving suggestions to help save
money in both fuel and repairs:
Drive smoothly. Accelerate at a moder-
ate rate. Don't make “kangaroo” starts or full-throttle shifts and maintain a
steady cruising speed. Don't race
between stoplights. Try to adjust your
speed to that of the other traffic so you
don't have to change speeds unneces-
sarily. Avoid heavy traffic whenever
possible. Always maintain a safe dis-
tance from other vehicles so you can
avoid unnecessary braking. This also
reduces brake wear.
Drive at a moderate speed. The faster you drive, the more fuel your car uses.
Driving at a moderate speed, especial-
ly on the highway, is one of the most
effective ways to reduce fuel consump-tion. Don't "ride" the brake or clutch pedal.
This can increase fuel consumption
and also increase wear on these com-
ponents. In addition, driving with your
foot resting on the brake pedal may
cause the brakes to overheat, which
reduces their effectiveness and may
lead to more serious consequences.
Take care of your tyres. Keep them inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tyre
wear. Check the tyre pressures at leastonce a month.
Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting kerbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tyre wear and may
also result in other problems as well as
greater fuel consumption.
Keep your car in good condition. For better fuel economy and reduced
maintenance costs, maintain your carin accordance with the maintenance
schedule in Section 7. If you drive your
car in severe conditions, more frequentmaintenance is required (see Section
7 for details). Keep your car clean. For maximum
service, your vehicle should be kept
clean and free of corrosive materials. It
is especially important that mud, dirt,
ice, etc. not be allowed to accumulate
on the underside of the car. This extra
weight can result in increased fuel con-
sumption and also contribute to corro-sion.
Travel lightly. Don't carry unnecessary weight in your car. Weight reduces fuel
economy.
Don't let the engine idle longer than necessary. If you are waiting (and not
in traffic), turn off your engine and
restart only when you're ready to go.
Remember, your vehicle does not require extended warm-up. After the
engine has started, allow the engine to
run for 10 to 20 seconds prior to plac-
ing the vehicle in gear. In very cold
weather, however, give your engine a
slightly longer warm-up period.
Don't “labour” or “over-rev” the engine. Labouring is driving too slowly in toohigh a gear resulting in the engine
bucking. If this happens, shift to a lower
gear. Over-revving is racing the engine
beyond its safe limit. This can be avoid-
ed by shifting at the recommended
speeds.

E120200AUN
Use high quality ethylene glycol coolant
Your vehicle is delivered with high quality
ethylene glycol coolant in the cooling
system. It is the only type of coolant that
should be used because it helps prevent
corrosion in the cooling system, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with themaintenance schedule in section 7.
Before winter, have your coolant tested toassure that its freezing point is sufficient
for the temperatures anticipated during
the winter. E120300AFD-EA
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in section
7. The level of charge in your battery can
be checked by an authorised HYUNDAI
dealer or a service station. E120400AFD-EA
Change to "winter weight" oil if
necessary In some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See section 9
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorised HYUNDAI dealer.
E120500AUN
Check spark plugs and ignition system
Inspect your spark plugs as described in
section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
CAUTION
Chains that are the wrong size or
improperly installed can damageyour vehicle's brake lines, sus-pension, body and wheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.
WARNING - Tyre chains
The use of chains may adversely affect vehicle handling.
Do not exceed 30 km/h (20 mph) or the chain manufacturer’s rec-
ommended speed limit, whichev-
er is lower.
Drive carefully and avoid bumps, holes, sharp turns, and other
road hazards, which may cause
the vehicle to bounce.
Avoid sharp turns or locked- wheel braking.
