Maintenance
Disc brake pads should be inspected
for wear whenever tyres are rotated.
Information
The outside and inside of an unsym-
metrical tyre is distinguishable. When
installing an unsymmetrical tyre, be
sure to install the side marked "out-
side" facing the outside. If the side
marked "inside" is installed on the
outside, it will have a negative effect
on vehicle performance.
Wheel alignment and tyre bal-
ance
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 need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
Incorrect wheel weights can dam-
age your vehicle’s aluminium
wheels. Use only approved wheel
weights.

■ With a full-size spare tyre (if equipped)
■Without a spare tyre
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 may cause loss of
vehicle control resulting in an
accident.

Tyre replacement
If the tyre is worn evenly, a tread
wear indicator will appear as a solid
band across the tread. This shows
there is less than 1.6 mm 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.When replacing the tyres, recheck
and tighten the wheel nuts after
driving about 620 mile. If the steer-
ing wheel shakes or the vehicle
vibrates while driving, the tyre is
out of balance. Align the tyre bal-
ance. If the problem is not solved,
we recommend that you contact
an authorised HYUNDAI dealer.
NOTICE
OLMB073027
Tread wear indicatorTo reduce the risk of DEATH or
SERIOUS INJURY:
Replace tyres that are worn,
show uneven wear, or are
damaged. Worn tyres can
cause loss of braking effec-
tiveness, steering control, and
traction.
Always replace tyres with the
same size as each tyre that
was originally supplied with
this vehicle. Using tyres and
wheels other than the recom-
mended sizes could cause
unusual handling characteris-
tics, poor vehicle control, or
negatively affect your vehi-
cle’s Anti-Lock Brake System
(ABS) resulting in a serious
accident.

Maintenance
(Continued)
When replacing tyres (or
wheels), it is recommended to
replace the two front or two
rear tyres (or wheels) as a
pair. Replacing just one tyre
can seriously affect your vehi-
cle’s handling.
Tyres degrade over time, even
when they are not being used.
Regardless of the remaining
tread, HYUNDAI recommends
that tyres be replaced after six
(6) years of normal service.
Heat caused by hot climates or
frequent high loading condi-
tions can accelerate the aging
process. Failure to follow this
warning may cause sudden
tyre failure, which could lead
to a loss of vehicle control
resulting in an accident.
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 and
type of tyre and wheel that is
different form 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 tires, be sure to equipped
all four tires with the tire and
wheel of the same size, type,
tread, brand and load-carrying
capability.
(Continued)
(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 tire can
seriously affect your vehicle’s
handling.
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 ESC(Electronic Stability
Control)(if equipped) to work
irregularly.

Consult an authorised HYUNDAI
dealer to replace most vehicle light
bulbs. It is difficult to replace vehicle
light bulbs because other parts of the
vehicle must be removed before you
can get to the bulb. This is especially
true for removing the headlamp
assembly to get to the bulb(s).
Removing/installing the headlamp
assembly can result in damage to
the vehicle.Be sure to replace the burned-out
bulb with one of the same wattage
rating. Otherwise, it may cause
damage to the fuse or electrical
wiring system.
Information
The headlamp and tail lamp lenses
could appear frosty if the vehicle is
washed after driving or the vehicle is
driven at night in wet weather. This
condition is caused by temperature dif-
ference between the lamp inside and
outside and, it does not indicate a prob-
lem with your vehicle. When moisture
condenses in the lamp, it will be
removed after driving with the head-
lamp on. The removable level may dif-
fer depending on lamp size, lamp posi-
tion and environmental condition.
However, if moisture is not removed,
we recommend that your vehicle is
inspected by an authorised HYUNDAI
dealer.
Information
The headlamp aiming should be adjust-
ed after an accident or after the head-
lamp assembly is reinstalled, at an
authorised HYUNDAI dealer.

NOTICE
Prior to working on a light, firmly
apply the parking brake, ensure
that the ignition switch is in the
LOCK/OFF position and turn off
the lights to avoid sudden move-
ment of the vehicle and burning
your fingers or receiving an elec-
tric shock.

Exterior care
Exterior 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 maintenance
Washing
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
driving, 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. Do not use strong soap, chemi-
cal detergents or hot water, and
do not wash the vehicle in direct
sunlight 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
the windows and wet the interior.
To prevent damage to the plastic
parts and lamps, do not clean
with chemical solvents or strong
detergents.
NOTICE
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.

Maintenance
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 preser-
vative 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
preservative. 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
collect on the underbody. If these
materials are not removed, acceler-
ated 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 under-
body and wheel openings with luke-
warm or cold water once a month,
after off-road driving and at the end of
each winter. Pay special 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.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.WARNING

Refer to “Fuel Requirements” in the Introduction chapter.
Always be sure to clean the area around any filler plug, drain plug, or dipstick before checking or draining
any lubricant. This is especially important in dusty or sandy areas and when the vehicle is used on unpaved
roads. Cleaning the plug and dipstick areas will prevent dirt and grit from entering the engine and other
mechanisms that could be damaged.
CAUTION
Recommended SAE viscosity number
Engine oil viscosity (thickness) has an effect on fuel economy and cold weather operating (engine start and engine
oil flowability). Lower viscosity engine oils can provide better fuel economy and cold weather performance, however,
higher viscosity engine oils are required for satisfactory lubrication in hot weather. Using oils of any viscosity other
than those recommended could result in engine damage.
