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 complete
buckle engagement.
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.
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.
When to replace seat belts
Entire in-use seat belt assembly or
assemblies should be replaced if the
vehicle has been involved in an accident.
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 bags
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
(Continued)
Problems may arise if the sensor
installation angles are changed
due to the deformation of the
front bumper, body or B and C pil-
lars 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 bumper guards or
replacing a bumper with non-gen-
uine parts may adversely affect
your vehicle’s collision and air
bag deployment performance.WARNING
Do not hit or allow any objects to impact the locations where air
bags 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.

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
when you turn the ignition ON, or if it 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, the frontpassenger's panel, front seats and roof
rails must be performed by an authorised
HYUNDAI dealer. 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 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 pro-cedures could increase the risk
of personal injury.
If your car was flooded and has soaked carpeting or water on the
flooring, you shouldn't try to start
the engine; have the car towed to
an authorised HYUNDAI dealer.

Trip computer
The trip computer is a microcomputer-
controlled driver information system that
displays information related to driving on
the display when the ignition switch is in
the ON position. All stored driving infor-
mation (except odometer) is reset if the
battery is disconnected.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.
The odometer is always displayed until
the display is turned off.

✽✽NOTICE
 Replace the filter according to the Maintenance Schedule.
If the vehicle is being driven in severe
conditions such as dusty or rough
roads, more frequent air conditioner
filter inspections and changes are
required.
 When the air flow rate suddenly
decreases, the system should be
checked at 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 negativeimpact on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorised HYUNDAI dealer.
✽✽ NOTICE
It is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor
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
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. 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 sec-
tion 7, “Maintenance”.
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 D (Drive) or R (Reverse).
WARNING
Driving whilst distracted can result
in a loss of vehicle control, that
may lead to an accident, severe
personal injury, and death. The dri-
ver’s primary responsibility is in
the safe and legal operation of a
vehicle, and use of any handheld
devices, other equipment, or vehi-
cle systems which take the driver’s
eyes, attention and focus away
from the safe operation of a vehicle
or which are not permissible by law
should never be used during oper-
ation of the vehicle.

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 pedal. This can
increase fuel consumption and also
increase wear on these components.
In addition, driving with your foot rest-
ing 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.
