PARKING BRAKE
Checking the parking brake
Type A
Check whether the stroke is within spec-
ification when the parking brake pedal is
depressed with 20 kg (44 lb, 196N) of
force. 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 authorised
HYUNDAI dealer.
Stroke : 4~5 notch
Type B
Check the stroke of the parking brake by
counting the number of “clicks’’ heardwhilst 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 authorised
HYUNDAI dealer.
Stroke : 5 “clicks’’ at a force of 20 kg (44 lbs, 196 N).

Maintenance
Disc brake pads should be inspectedfor wear whenever tyres are rotated.
✽✽ NOTICE
Rotate radial tyres that have an
asymmetric tread pattern only from
front to rear and not from right to
left.
Wheel alignment and tyre balance
The wheels on your vehicle were aligned and balanced carefully at the
factory to give you the longest tyre
life and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tyre
wear or your vehicle pulling one way
or the other, the alignment may needto be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.

Without a spare tyre
With a full-size spare tyre (if equipped) Directional tyres (if equipped)WARNING
Do not use the compact spare tyre for tyre rotation.
Do not mix bias ply and radial ply tyres 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 can
damage your vehicle's alu-minum wheels. Use onlyapproved wheel weights.

Tyre replacement
If the tyre is worn evenly, a tread
wear indicator will appear as a solid
band across the tread. This showsthere is less than 1.6 mm (1/16 inch)
of tread left on the tyre. Replace the
tyre when this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tyre.
OEN076053
Tread wear indicator(Continued)
The use of any other tyre size
or type may seriously affect
ride, handling, ground clear-
ance, stopping distance, body
to tyre clearance, snow tyre
clearance, and speedometer
reliability.
It is best to replace all four tyres at the same time. If that
is not possible, or necessary,
then replace the two front or
two rear tyres as a pair.Replacing just one tyre can
seriously affect your vehicle’shandling.
The ABS works by comparing the speed of the wheels. Tyre
size can affect wheel speed.
When replacing tyres, all 4
tyres must use the same size
originally supplied with the
vehicle. Using tyres of a dif-
ferent size can cause the ABS
(Anti-lock Brake System) and
ESP (Electronic Stability
Program) or ESC (Electronic
Stability Control) (if equipped)
to work irregularly.WARNING - Replacing
tyres
Driving on worn-out tyres is very hazardous and will
reduce braking effectiveness,
steering accuracy, and trac-tion.
Your vehicle is equipped with tyres designed to provide for
safe ride and handling capa-
bility. Do not use a size andtype of tyre and wheel that is
different from the one that is
originally installed on your
vehicle. It can affect the safety
and performance of your vehi-
cle, which could lead to han-
dling failure or rollover and
serious injury. When replacing
the tyres, be sure to equip all
four tyres with the tyre and
wheel of the same size, type,
tread, brand and load-carrying
capacity.

LIGHT BULBS
Use only the bulbs of the specifiedwattage.
All bulbs are available from yourHYUNDAI dealers Parts Department.
✽✽ NOTICE
After 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 authorised 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 tothe 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 wattagerating. Otherwise, it may causedamage to the fuse or electricwiring system.
CAUTION
If you don’t have necessary tools,the correct bulbs and the expertise,
consult an authorised HYUNDAIdealer. In many cases, it is difficultto replace vehicle light bulbs because other parts of the vehicle
must be removed before you canget to the bulb. This is especiallytrue if you have to remove the head-
light assembly to get to the bulb(s).Removing/installing the headlightassembly can result in damage tothe vehicle.

Exterior care
Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning andcaution statements that appear on thelabel.
Finish maintenance
Washing
To help protect your vehicle’s finish from
rust and deterioration, wash it thoroughlyand 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 keptclear 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.
APPEARANCE CARECAUTION
Do not use strong soap, chemical
detergents or hot water, and do
not wash the vehicle in direct sunlight or when the body of thevehicle 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 clean
with chemical solvents or strongdetergents.
WARNING - Wet brakes
After washing the vehicle, test the
brakes whilst driving slowly to see
if they have been affected by water.
If braking performance is impaired,
dry the brakes by applying them
lightly whilst maintaining a slow
forward speed.

Bright-metal maintenance
To remove road tar and insects, use a
tar remover, not a scraper or other
sharp object.
To protect the surfaces of bright-metal parts from corrosion, apply a coating of
wax or chrome preservative and rub to
a high luster.
During winter weather or in coastal areas, cover the bright metal parts with
a heavier coating of wax or preserva-
tive. If necessary, coat the parts with
non-corrosive petroleum jelly or other
protective compound.
Underbody maintenance
Corrosive materials used for ice and
snow removal and dust control may col-
lect on the underbody. If these materials
are not removed, accelerated rusting can
occur on underbody parts such as the
fuel lines, frame, floor pan and exhaust
system, even though they have been
treated with rust protection.
Thoroughly flush the vehicle underbody
and wheel openings with lukewarm or
cold water once a month, after off-road
driving and at the end of each winter. Payspecial attention to these areas because
it is difficult to see all the mud and dirt. It
will do more harm than good to wet down
the road grime without removing it. The
lower edges of doors, rocker panels, and
frame members have drain holes that
should not be allowed to clog with dirt;
trapped water in these areas can cause
rusting.WARNING
After washing the vehicle, test the
brakes whilst driving slowly to see
if they have been affected by water.
If braking performance is impaired,
dry the brakes by applying them
lightly whilst maintaining a slow
forward speed.
