Checking the parking brakeType ACheck whether the stroke is within spec-
ification when the parking brake pedal is
depressed with 44 lb (20 kg, 196 N) of
force. Also, the parking brake alone should
securely hold the vehicle on a fairly steep
grade. If the stroke is more or less than
specified, have the parking brake adjusted
by an authorized HYUNDAI dealer.
Stroke : 4~5 notch
Type BCheck the stroke of the parking brake by
counting the number of “clicks’’ heard
while fully applying it from the released
position. Also, the parking brake alone
should securely hold the vehicle on a fair-
ly steep grade. If the stroke is more or
less than specified, have the parking
brake adjusted by an authorized
HYUNDAI dealer.
Stroke : 5 “clicks’’ at a force of
44 lbs (20 kg, 196 N).

WARNING -
Coolant
 Do not use radiator coolant orantifreeze in the washer fluid
reservoir.
 Radiator coolant can severely obscure visibility when sprayed
on the windshield and may cause
loss of vehicle control or damage
to paint and body trim.
 Windshield washer fluid agents contain some amounts of alcohol
and can be flammable under cer-
tain circumstances. Do not allow
sparks or flame to contact the
washer fluid or the washer fluid
reservoir. Damage to the vehicle
or occupants could occur.
 Windshield washer fluid is poi- sonous to humans and animals.
Do not drink and avoid contacting
windshield washer fluid. Serious
injury or death could occur.

Maintenance40
7Disc brake pads should be inspected
for wear whenever tires are rotated.✽
✽ NOTICERotate radial tires that have an
asymmetric tread pattern only from
front to rear and not from right to
left.
Wheel alignment and tire balance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
OBH078040
Without a spare tire
WARNING
 Do not use the compact spare
tire for tire rotation.
 Do not mix bias ply and radial ply tires under any circum-
stances. This may cause
unusual handling characteris-
tics that could result in death,
severe injury, or property
damage.
CAUTION
Improper wheel weights candamage your vehicle's alu-minum wheels. Use onlyapproved wheel weights.

Maintenance
Tire replacement
If the tire is worn evenly, a tread wear
indicator will appear as a solid band
across the tread. This shows there is
less than 1/16 inch (1.6 mm) of tread
left on the tire. Replace the tire when
this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tire.

Tread wear indicator
WARNING
- Replacingtires
To reduce the chance or serious
or fatal injuries from an acci-
dent caused by tire failure or
loss of vehicle control:
 Replace tires that are worn, show uneven wear, or are
damaged. Worn tires can
cause loss of braking effec-
tiveness, steering control, and
traction.
 Do not drive your vehicle with too little or too much pressure
in your tires. This can lead to
uneven wear and tire failure.
 When replacing tires, never mix radial and bias-ply tires
on the same car. You must
replace all tires (including the
spare) if moving from radial to
bias-ply tires.
(Continued)
(Continued)
 Using tires and wheel otherthan the recommended sizes
could cause unusual handling
characteristics and poor vehi-
cle control, resulting in a seri-
ous accident.
 Wheels that do not meet HYUNDAI’s specifications
may fit poorly and result in
damage to the vehicle or
unusual handling and poor
vehicle control.
 The ABS works by comparing the speed of the wheels. Tire
size can affect wheel speed.
When replacing tires, all 4
tires must use the same size
originally supplied with the
vehicle. Using tires of a differ-
ent size can cause the ABS
(Anti-lock Brake System) and
ESC (Electronic Stability
Control) to work irregularly.

Maintenance
LIGHT BULBSUse only bulbs of the specified wattage.
✽
✽NOTICEAfter heavy, driving rain or washing,
headlight and taillight lenses could
appear frosty. This condition is caused by
the temperature difference between the
lamp inside and outside. This is similar
to the condensation on your windows
inside your vehicle during the rain and
doesn’t indicate a problem with your
vehicle. If the water leaks into the lamp
bulb circuitry, have the vehicle checked
by an authorized HYUNDAI dealer.
WARNING
- Working on
the lights
Prior to working on the light, firmly
apply the parking brake, ensure
that the ignition switch is turned to
the LOCK position and turn off the
lights to avoid sudden movement
of the vehicle and burning your fin-
gers or receiving an electric shock.
CAUTION
Be sure to replace the burned-out
bulb with one of the same wattage rating. Otherwise, it may causedamage to the fuse or electric wiring system.
CAUTION
If you don’t have necessary tools,the correct bulbs and the expertise,consult an authorized HYUNDAIdealer. In many cases, it is difficult to replace vehicle light bulbsbecause other parts of the vehiclemust be removed before you canget to the bulb. This is especially true if you have to remove the head-light assembly to
get to the bulb(s).
Removing/installing
the headlight
assembly can result in damage to the vehicle.

Maintenance
APPEARANCE CAREExterior careExterior general caution It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning and
caution statements that appear on the
label.Finish maintenanceWashing
To help protect your vehicle’s finish from
rust and deterioration, wash it thoroughly
and frequently at least once a month with
lukewarm or cold water.
If you use your vehicle for off-road driv-
ing, you should wash it after each off-
road trip. Pay special attention to the
removal of any accumulation of salt, dirt,
mud, and other foreign materials. Make
sure the drain holes in the lower edges of
the doors and rocker panels are kept
clear and clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar deposits
can damage your vehicle’s finish if not
removed immediately.
Even prompt washing with plain water
may not completely remove all these
deposits. A mild soap, safe for use on
painted surfaces, may be used.After washing, rinse the vehicle thor-
oughly with lukewarm or cold water. Do
not allow soap to dry on the finish.
CAUTION
 Do not use strong soap, chemical
detergents or hot water, and donot wash the vehicle in directsunlight or when the body of the vehicle is warm.
 Be careful when washing the side windows of your vehicle.Especially, with high-pressure water, water may leak through thewindows and wet the interior.
 To prevent damage to the plastic parts and lamps, do not cleanwith chemical solvents or strong detergents.
WARNING -
Wet brakes
After washing the vehicle, test the
brakes while driving slowly to see if
they have been affected by water. If
braking performance is impaired,
dry the brakes by applying them
lightly while maintaining a slow for-
ward speed.
CAUTION
 Water washing in the engine com- partment including high pressurewater washing may cause the fail-ure of electrical circuits or engineand related components locatedin the engine compartment.
 Never allow water or other liquids to come in contact with electri-cal/electronic components andair duct inside the vehicle as this may damage them.

Maintenance
Aluminum wheel maintenance The aluminum wheels are coated with a
clear protective finish.
 Do not use any abrasive cleaner, pol-ishing compound, solvent, or wire
brushes on aluminum wheels. They
may scratch or damage the finish.
 Use only a mild soap or neutral deter- gent, and rinse thoroughly with water.
Also, be sure to clean the wheels after
driving on salted roads. This helps pre-
vent corrosion.
 Avoid washing the wheels with high- speed car wash brushes.
 Do not use any cleaners containing acid or acid detergents. It may damage
and corrode the aluminum wheels
coated with a clear protective finish.
Corrosion protectionProtecting your vehicle from corrosion
By using the most advanced design and
construction practices to combat corro-
sion, we produce cars of the highest
quality. However, this is only part of the
job. To achieve the long-term corrosion
resistance your vehicle can deliver, the
owner's cooperation and assistance is
also required.
Common causes of corrosion
The most common causes of corrosion
on your car are:
 Road salt, dirt and moisture that isallowed to accumulate underneath the
car.
 Removal of paint or protective coatings by stones, gravel, abrasion or minor
scrapes and dents which leave unpro-
tected metal exposed to corrosion.
WARNING
After washing the vehicle, test the
brakes while driving slowly to see if
they have been affected by water. If
braking performance is impaired,
dry the brakes by applying them
lightly while maintaining a slow for-
ward speed.

Specifications, Consumer information, Reporting safety defects48RECOMMENDED LUBRICANTS AND CAPACITIES To help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality. The correct
lubricants also help promote engine efficiency that results in improved fuel economy.These lubricants and fluids are recommended for use in your vehicle.*1Refer to the recommended SAE viscosity numbers on the next page.
*2Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econo my by reducing
the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure in everyday driving, but in a year’s
time, they can offer significant cost and energy savings.
