Wheel Replacement
When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim widthand offset.
Tire Traction
Tire traction can be reduced if you
drive on worn tires, tires that are
improperly inflated or on slippery
road surfaces. Tires should be
replaced when tread wear indicators
appear. To reduce the possibility of
losing control, slow down whenever
there is rain, snow or ice on the road.
Tire Maintenance
In addition to proper inflation, correct wheel alignment helps to decrease
tire wear. If you find a tire is worn
unevenly, have your dealer check thewheel alignment.
When you have new tires installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tire life. Additionally, a tire should
always be rebalanced if it is removedfrom the wheel.
Tire Sidewall Labeling
This information identifies and
describes the fundamental charac-
teristics of the tire and also provides
the tire identification number (TIN)
for safety standard certification. TheTIN can be used to identify the tire incase of a recall.
Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, HYUNDAI recommendsthat tires be replaced after six
(6) years of normal service.
When replacing tires (or
wheels), it is recommended to
replace the two front or two
rear tires (or wheels) as a pair.Replacing just one tire can
seriously affect your vehicle'shandling.
Heat caused by hot climates or frequent high loading con-ditions can accelerate the
aging process. Failure to fol-
low this warning may cause
sudden tire failure, which
could lead to a loss of vehicle
control resulting in an acci-dent.

6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.
7. Uniform tire quality grading
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and maxi-
mum section width.
For example:
TREAD wear 200
TRACTION AA
TEMPERATURE A
Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate ofthe tire when tested under controlled
conditions on a specified govern-
ment test course. For example, a tire
graded 150 would wear one-and-a-
half times (1½) as well on the gov-
ernment course as a tire graded 100.
The relative performance of tiresdepends upon the actual conditions
of their use, however, and may
depart significantly from the norm
due to variations in driving habits,
service practices and differences in
road characteristics and climate.
These grades are molded on the
sidewalls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicle
may vary with respect to grade.
Traction - AA, A, B & C
The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tire's ability to
stop on wet pavement as measuredunder controlled conditions on spec-
ified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perform-
ance.The traction grade assigned tothis tire is based on straight-ahead braking traction tests,
and does not include accelera-
tion, cornering, hydroplaning,
or peak traction characteristics.
WARNING

7-38
Maintenance
Temperature - A, B & C
The temperature grades are A (the highest), B and C representing the
tire’s resistance to the generation ofheat and its ability to dissipate heatwhen tested under controlled condi-
tions on a specified indoor laboratorytest wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. Grades B and A
represent higher levels of perform-
ance on the laboratory test wheel
than the minimum required by law.
Tire Terminology and Definitions
Air Pressure
The amount of air inside the tire
pressing outward on the tire. Air
pressure is expressed in kilopascal
(kPa) or pounds per square inch(psi).
Accessory Weight
This means the combined weight of
optional accessories. Some exam-
ples of optional accessories are
reduction gear, power seats, and airconditioning.
Aspect Ratio
The relationship of a tire's height toits width.
Belt
A rubber coated layer of cords that is
located between the plies and the
tread. Cords may be made from steel
or other reinforcing materials.
The temperature grade for this
tire is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
under-inflation, over-inflation,
or excessive loading, either
separately or in combination,
can cause heat build-up and
possible sudden tire failure.
This may cause loss of vehicle
control resulting in an accident.

Maintenance
Longer wearing tires can be more
susceptible to irregular tread wear. It
is very important to follow the tire
rotation interval in this chapter to
achieve the tread life potential of
these tires. Cuts and punctures in
radial-ply tires are repairable only in
the tread area, because of sidewall
flexing. Consult your tire dealer for
radial-ply tire repairs.Low Aspect Ratio Tires
Low aspect ratio tires, the aspect
ratio is lower than 50, are provided
for sporty looks.
Because low aspect ratio tires are
optimized for handling and braking,
their sidewall is a little stiffer than a
standard tire. Also low aspect ratiotires tend to be wider and conse-
quently have a greater contact patch
with the road surface. In some
instances they may generate moreroad noise compared with standard
tires.
Do not mix bias ply and radial
ply tires under any circum-
stances. This may cause unusu-
al handling characteristics that
may cause loss of vehicle con-
trol resulting in an accident.
WARNING
Because the sidewall of a low
aspect ratio tire is shorter than
a standard tire, the rim of thewheel and the tire itself is more
easily susceptible to damage.Use caution when driving and
follow the guidelines below to
help minimize damage to thewheel and tire:
- When driving on a rough road
or off road, drive cautiously
because tires and wheels may
be damaged. And after driving,inspect tires and wheels.
- When passing over a pothole, speed bump, manhole, or curb
stone, drive slowly so that thetires and wheels are not dam-
aged.
- If the tire is subjected to a severe impact, have the tire
and wheel inspected by an
authorized HYUNDAI dealer.
- Inspect the tire condition and pressure every 3,000 km(1,800 miles).

FFUU SSEE SS
A vehicle's electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver's side panel
bolster, the other in the fuel cell
power module compartment near the
battery. If any of your vehicle’s lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside the
fuse will be melted or broken.
If the electrical system does not
work, first check the driver's side
fuse panel. Before replacing a blown
fuse, turn the vehicle and all switch-
es off, and then disconnect the neg-
ative battery cable. Always replace a
blown fuse with one of the same rat-ing.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized
HYUNDAI dealer.
Information
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and multi fuse for higher
amperage ratings.
i
NEVER replace a fuse with any-
thing but another fuse of thesame rating.
A higher capacity fuse could
cause damage and possibly
cause a fire.
Do not install a wire or alu-
minum foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
possibly a fire.

Consult an authorized 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.
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
difference between the lamp inside
and outside and, it does not indicate a
problem with your vehicle. When
moisture condenses in the lamp, it will
be removed after driving with the
headlamp on. The removable level
may differ depending on lamp size,
lamp position and environmental con-
dition. However, if moisture is not
removed, we recommend that your
vehicle is inspected by an authorized
HYUNDAI dealer. Information
 A normally functioning lamp may flicker momentarily to stabilize the
vehicle's electrical control system.
However, if the lamp goes out after
flickering momentarily, or contin-
ues to flicker, we recommend the
system be checked by an authorized
HYUNDAI dealer.
 The parking lamp may not turn on when the parking lamp switch is
turned on, but the parking lamp
and headlamp switch may turn on
when the headlamp switch is turned
on. This may be caused by network
failure or vehicle electrical control
system malfunction. If this occurs,
we recommend the system be
checked by an authorized
HYUNDAI dealer.i
i
Prior to replacing a lamp, shift
to P (Park), apply the parking
brake, place the POWER but-ton in the OFF position and
take the key with you when
leaving the vehicle to avoid
sudden movement of the vehi-
cle and to prevent possible
electric shock.
Be aware the bulbs may be
hot and may burn your fin-
gers.

Maintenance
1. Using a flat-blade screwdriver,gently pry the lens from the interi- or lamp housing.
2. Remove the bulb by pulling it straight out.
3. Install a new bulb in the socket.
4. Align the lens tabs with the interi- or lamp housing notches and snap
the lens into place.
Use care not to dirty or damage
lens, lens tab, and plastic hous-ings.
NOTICE
Prior to working on the Interior
Lights, ensure that the lamp is
off to avoid burning your fingers
or receiving an electric shock.

Exterior Care
Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warningand caution statements that appearon the label.
High-pressure washing
When using high-pressure wash-
ers, make sure to maintain suffi-
cient distance from the vehicle.
Insufficient clearance or excessivepressure can lead to component
damage or water penetration.
Do not spray the camera, sensors or its surrounding area directly with
a high pressure washer. Shock
applied from high pressure water
may cause the device to not oper-
ate normally.
Do not bring the nozzle tip close to boots (rubber or plastic covers)or
connectors as they may be dam-
aged if they come into contact with
high pressure water.
Do not use any high-pressure noz- zles, which induce either one-direct
water stream or water swirling.
Protecting your vehicle’s finish
Washing
To help protect your vehicle’s finish
from rust and deterioration, wash itthoroughly 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 andclean.
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, should beused. After washing, rinse the vehicle thor-
oughly with lukewarm or cold water.
Do not allow soap to dry on the fin-ish.
After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water before getting on the
road. If braking performance is
impaired, dry the brakes by
applying them lightly while
maintaining a slow forwardspeed.

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 attentionto 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 rust-ing.
Aluminum wheel maintenance
The aluminum wheels are coated
with a clear protective finish.
Do not use abrasive cleaner, pol-
ishing compound, solvent, or
wire brushes on aluminumwheels.
Clean the wheel when it has cooled.
Use only a mild soap or neutral detergent, and rinse thoroughly
with water. Also, clean thewheels after driving on salted
roads.
Do not wash the wheels with high-speed car wash brushes.
Do not use any cleaners con- taining acid or alkaline deter-
gents.
NOTICE
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 forwardspeed.
