C020400AUN-EA Care of seat belts
Seat belt systems should never be disas-
sembled or modified. In addition, care
should be taken to assure that seat belts
and belt hardware are not damaged by
seat hinges, doors or other abuse.Maintenance of seat belts
When cleaning the seat belts, as recom-
mended, avoid getting solutions into the
buckle where they may attack the lubri-
cant or cause corrosion. Do not attempt
to bleach or re-dye belts, as this may
affect the webbing strength.
✽✽
NOTICE
Do not attempt any form of modifica-
tions or repairs to seat belt components.
If the retractor or other components do
not operate correctly, call an authorised
HYUNDAI dealer, who will take the
necessary corrective action. Your autho-
rised dealer will inspect all seat belt
components at regular intervals and
advise if replacement is required.Between these inspections you should
make regular checks to ensure that for-
eign objects are not preventing completebuckle engagement.
C020401AEN
Periodic inspection
All seat belts should be inspected peri-
odically for wear or damage of any kind.
Any damaged parts should be replaced
as soon as possible.
C020402AUN
Keep belts clean and dry
Seat belts should be kept clean and dry.
If belts become dirty, they can be
cleaned by using a mild soap solution
and warm water. Bleach, dye, strong
detergents or abrasives should not be
used because they may damage and
weaken the fabric. C020403AFD-EA
When to replace seat belts
If the vehicle has been involved in an
accident all seat belt in use at that time,
or belts where the pre-tensioner device
has been deployed must be replaced.
This should be done even if no damage
is visible. Additional questions concern-
ing seat belt operation should be directed
to an authorised HYUNDAI dealer.
WARNING
When you return the rear seatback to its upright position after the rear
seatback was folded down, be care-
ful not to damage the seat belt web-
bing or buckle. Be sure that the
webbing or buckle does not get
caught or pinched in the rear seat.
A seat belt with damaged webbing
or buckle will not be as strong and
could possibly fail during a colli-
sion or sudden stop, resulting in
serious injury.

Air bag inflation conditions
Front air bag
Front air bags are designed to inflate in a frontal collision depending on the intensi-
ty, speed or angles of impact of the frontcollision.
1JBA3513/H
WARNING
Do not hit or allow any objects to impact the locations where air bag
or sensors are installed.
This may cause unexpected air
bag deployment, which could
result in serious personal injuryor death.
If the installation location or angle of the sensors is altered in
any way, the air bags may deploy
when they should not or they may
not deploy when they should,
causing severe injury or death.
Therefore, do not try to perform
maintenance on or around the air
bag sensors. Have the vehicle
checked and repaired by an
authorised HYUNDAI dealer.
(Continued)(Continued)
Problems may arise if the sensorinstallation angles are changed
due to the deformation of the
front bumper, body or B pillar
where side collision sensors are
installed. Have the vehicle
checked and repaired by an
authorised HYUNDAI dealer.
Your vehicle has been designed to absorb impact and deploy the
air bag(s) in certain collisions.
Installing aftermarket bumper
guards or replacing a bumper
with non-genuine parts may
adversely affect your vehicles
collision and air bag deployment
performance.

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.

Fuel gauge
The fuel gauge indicates the approxi- mate amount of fuel remaining in the fuel
tank. The fuel tank capacity is given in
section 9. The fuel gauge is supplement-
ed by a low fuel warning light, which will
illuminate when the fuel tank is nearly
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 thetank. D150205ANF
Odometer/Tripmeter (if equipped)
Odometer (km or MI) The odometer indicates the total dis-
tance the vehicle has been driven.
You will also find the odometer useful to
determine when periodic maintenance
should be performed.
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 thewarning light comes on or when the
gauge indicator comes close to the
E level.

Before entering vehicle
• Be sure that all windows, outside mir-ror(s), and outside lights are clean.
Check the condition of the tyres.
Check under the vehicle for any sign of leaks.
Be sure there are no obstacles behind you if you intend to back up.
E020200AUN
Necessary inspections
Fluid levels, such as engine oil, engine
coolant, brake fluid, and washer fluid
should be checked on a regular basis,
with the exact interval depending on the
fluid. Further details are provided in
Section 7, “Maintenance”.
E020300AUN-EA
Before starting
Close and lock all doors.
Position the seat so that all controls are easily reached.
Adjust the inside and outside rearview mirrors. Be sure that all lights work.
Check all gauges.
Check the operation of warning lights
when the ignition switch is turned to the ON position.
Release the parking brake and make sure the brake warning light goes out.
For safe operation, be sure you are famil-
iar with your vehicle and its equipment.
BEFORE DRIVING
WARNING
All passengers must be properly
belted whenever the vehicle is mov-
ing. Refer to “Seat belts” in section
3 for more information on their
proper use.
WARNING
Always check the surrounding
areas near your vehicle for people,
especially children, before putting a
car into “Drive” or “Reverse”.
WARNING
When you intend to park or stop the
vehicle with the engine on, be care-ful not to depress the accelerator
pedal for a long period of time. It
may overheat the engine or exhaust
system and cause fire.
WARNING - Driving under
the influence of alcohol or drugs
Driving under the influence of
drugs or alcohol is dangerous and
is one of the major contributing fac-
tors to the road deaths each year.Even a small amount of alcohol will
affect your reflexes, perceptions
and judgement. Driving while under
the influence of drugs is as danger-
ous or more dangerous than driv-ing drunk.
You are much more likely to have a
serious accident if you drink or
take drugs and drive.
If you are drinking or taking drugs,
don’t drive. Do not ride with a driv-er who has been drinking or taking
drugs. Choose a designated driveror call a cab.

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.
ECONOMICAL OPERATION

533
Driving your vehicle
Use your air conditioning sparingly.The air conditioning system is operat-
ed by engine power so your fuel econ-
omy is reduced when you use it.
Open windows at high speeds can reduce fuel economy.
Fuel economy is less in crosswinds and headwinds. To help offset some of
this loss, slow down when driving in
these conditions.
Keeping a vehicle in good operating con-
dition is important both for economy and
safety. Therefore, have an authorised
HYUNDAI dealer perform scheduled
inspections and maintenance.
WARNING - Engine off dur-
ing motion
Never turn the engine off to coast
down hills or anytime the vehicle is
in motion. The power steering and
power brakes will not function
properly without the engine run-
ning. Instead, keep the engine on
and downshift to an appropriate
gear for engine braking effect. In
addition, turning off the ignition
while driving could engage the
steering wheel lock resulting in
loss of vehicle steering which
could cause serious injury ordeath.

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.

When you are ready to leave after park- ing on a hill
1. With the manual transaxle in Neutral
or automatic transaxle in P (Park),
apply your brakes and hold the brake
pedal down while you:

and

2. Slowly remove your foot from the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks. E140500AUN-EA
Maintenance when trailer towing
Your vehicle will need service more often
when you regularly towing a trailer.
Important items to pay particular atten-tion to include engine oil, automatic
transaxle fluid, axle lubricant and cooling
system fluid. Brake condition is another
important item to check frequently. Each
item is covered in this manual, and the
Index will help you find them quickly. If
you’re towing, it’s a good idea to review
these sections before you start your trip.
Don’t forget to also maintain your trailer
and towbar. Follow the maintenance
schedule that accompanied your trailer
and check it periodically. Preferably, con-
duct the check at the start of each day’s
driving. Most importantly, all towbar nutsand bolts should be tight.
WARNING
- Parking brake
It can be dangerous to get out of
your vehicle if the parking brake is
not firmly set.
If you have left the engine running,
the vehicle can move suddenly. You
or others can be seriously injured
or cause fatality.CAUTION
Due to higher load during trailer usage, overheating might occurin hot days or during uphill driv- ing. If the coolant gauge indicates
over-heating, switch off the A/C and stop the vehicle in a safe areato cool down the engine.
When towing check transaxle fluid more frequently.
If your vehicle is not equipped with the air conditioner, youshould install a condenser fan to improve engine performance
when towing a trailer.
