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.

vehicle is parked without being operated
for prolonged periods. Use the following
procedures before parking the vehicle for
prolonged periods.
1. Turn off the engine.
2. Turn off the headlights and tail lights.
3. Open the driver’s side panel cover and
pull up the memory fuse.

audio, clock and interior lamps, etc.,
will not operate. Some items must be
reset after replacement. Refer to
“Battery” in this section.
 Even though the memory fuse is
pulled up, the battery can still be dis-
charged by operation of the head-
lights or other electrical devices.
Engine compartment fuse replacement

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.

Maintenance
✽✽NOTICE
HID lamps have superior performance
vs. halogen bulbs. HID lamps are esti-
mated by the manufacturer to last twice
as long or longer than halogen bulbs
depending on their frequency of use.
They will probably require replacement
at some point in the life of the vehicle.
Cycling the headlamps on and off more
than typical use will shorten HID lamps
life. HID lamps do not fail in the same
manner as halogen incandescent lamps.
If a headlamp goes out after a period of
operation but will immediately relight
when the headlamp switch is cycled it is
likely the HID lamp needs to be
replaced. HID lighting components are
more complex than conventional halo-
gen bulbs thus have higher replacement
cost.
Headlight bulb
1. Open the bonnet.
2. Remove the headlight bulb cover by turning it counterclockwise.
3. Disconnect the headlight bulb socket- connector. 4. Unsnap the headlight bulb retaining
wire by depressing the end and push-
ing it upward.
5. Remove the bulb from the headlight assembly.
6. Install a new headlight bulb (without touching the bulb glass, only hold by
metal backing) and snap the headlight
bulb retaining wire into position by
aligning the wire with the groove on
the bulb.
7. Connect the headlight bulb socket- connector.
8. Install the headlight bulb cover by turn- ing it clockwise.
✽✽ NOTICE
If the headlight aiming adjustment is
necessary after the headlight assembly is
reinstalled, consult an authorised
HYUNDAI dealer.
