1.+#,204/3424-3D
Do not allow brake/clutch fluid to
contact the vehicle's body paint, as
paint damage will result.
Brake/clutch fluid, which has been
exposed to open air for an extended
time should never be used as its
qualit y cannot be guaranteed. It
should be properly disposed. Don't
put in the wrong kind of fluid. A few
drop s of mineral-based oil, such as
engine oil, in your brake/clutch sys-
tem can damage brake/clutch sys-
t em parts. NOTICE
Brake/clutch fluid
When changing and adding
brake/clutch fluid, handle it care-
fully. Do not let it com e in contact
with your eyes. If brake/clutch fluid
come in contact with your eyes,
immediately flush the m with a
large quantity of fresh tap water.
Have your eyes examined by a
doctor as soon as possible.

 $#!Checking the washer fluid level Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary. Plain water may be used if
washer fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.
Checking the parking brakeCheck 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 fairly steep
grade. If the stroke is more or less
than specified, we recommend that
the system be inspected by an
authorized HYUNDAI dealer.Stroke : 6~8 “clicks’’ at a force of 20
kg (44 lbs, 196 N).

Coolant•
Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
•
Radiator coolant can severely
obscure visibility when sprayed
on the windshield and may
cause loss of ve hicle control or
damage to the paint and body
trim.
•
Windshield washer fluid agents
contain some amounts of alco-
hol and can be flammable under
certain circ umstances. Do not
allow sparks or flame come in
contact with the washer fluid or
the washer fluid reser voir.
Damage to the vehicle or occu- pants could occur.
•
Windshield washer fluid is poi-
sonous to humans and animals. Do not drink and avoid coming
in contact with the windshield
washer fluid. Serious injury or
death could occur.

1.(%,204/3424-3TTire rotation To equalize tread wear, it is recom-
mended that the tires be rotated
every 10,000 km (6,200 miles) or
sooner if irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out-
of-balance wheels, severe braking or
severe cornering. Look for bumps or
bulges in the tread or side of tire.
Replace the tire if you find either of
these conditions. Replace the tire if
fabric or cord is visible. After rotation,
be sure to bring the front and rear tire
pressures to specification and check
lug nut tightness.
Refer to “Tire and wheels” in chapter
8. Disc brake pads should be inspected
for wear whenever tires are rotated.
Information
Rotate radial tires that have an asym-
metric tread pattern only from front
to rear and not from right to left.i•
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 unusu-
al handling ch aracteristics that
could result in death, severe
injury, or property damage.

CCompact spare tire replacement
(if equipped)A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the
tread wear indicator bars on the tire.
The replaced compact spare tire
should be the same size and design
tire as the one provided with your
new vehicle and should be mounted
on the same compact spare tire
wheel. The compact spare tire is not
designed to be mounted on a regular
size wheel, and the compact spare
tire wheel is not designed to mount a
regular size tire.
(Continued)•
Do not drive your vehicle with
too little or too much pressure in
your tires. This can lead to
uneven we ar and tire failure.
•
When replacing tires, never mix
radial and bias-ply tires on the
same car. You must replace all
tires (i ncluding the spare) if mov-
ing from radial to bias-ply tires.
•
It is best to replace all four tires at
the same time. If that is not possi-
ble, or necessary, then re place the
two front or two rear tires as a pair.
Replacing just one tire can serious-
ly affect your veh icle’s handling.
•
Using tires and wheel other than
the recommended sizes could
cause unusual handling charac-
teristics an d poor vehicle con-
trol, resulting in a serious acci-
dent.

•
Wheels that do not meet
HYUNDAI's specifications may
fit poorly and result in damage to
the vehicle or u nusual handling
and poor vehicle control.
•
The ABS works by comparing
the speed of the wheels. Tire
size can affect wheel speed.
When replacing ti res, all 4 tires
must use the same size original-
ly supplied with the vehicle.
Using tires of a differe nt size can
cause the ABS (Anti-lock Brake
System) and ESC (Electronic
Stability Control) to work irregu -
larly. (if equipped)

1.$#,204/3424-3!#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 headlight
assembly to get to the bulb(s).
Removing/installing the headlight
assembly can result in damage to
the vehicle.
Information
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 dur-
ing the rain and doesn’t indicate a
problem with your vehicle. If the
water leaks into the lamp bulb circuit-
ry, we recommend that the system be
checked by an authorized HYUNDAI
dealer.
Be sure to replace the burned-out
bulb with one of the same wattage
rating. Otherwise, it may cause dam -
age to the fuse or electric wiring sys-
tem.
i
Prior to replacing a light, depress
the foot brake, move the shift lever
into the P (Park, for Continuo usly
Variable Transaxle vehicle) or
neutral (for Manual Transaxle
vehicle), apply the parking brake,
plac e the ignition switch in the
LOCK/OFF position, and take the
key with you when leaving the
vehicle to av oid sudden move-
ment of the vehicle and to prevent
possible electric shock.
Be aware the bulbs may be h ot
and may burn your fingers.

$  "$# $Exterior 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. High-pressure washing• When using high-pressure washers,
make sure to maintain sufficient dis-
tance from the vehicle.
Insufficient clearance or excessive
pressure 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 appliedfrom high pressure water may cause
the device to not operate normally.• Do not bring the nozzle tip close to boots (rubber or plastic covers) or
connectors as they may be damaged
if they come into contact with high
pressure water.
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
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 fin-
ish.
• Do not use strong soap, chemicaldetergents or hot water, and do not
wash the vehicle in direct sunlig ht
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 dam age to the plastic
parts and lamps, do not clean with
chemical solvents or strong deter- gents. NOTICEWet 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 apply-
ing them lightly while maint aining
a slow forward speed.
WARNING

BBright-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 maintenanceCorrosive 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 the under-
body 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 the doors, rocker
panels, and frame members have
drain holes that should not clog with
dirt; trapped water in these areas can
cause rusting.
After washing the vehicle, test the
brakes while driving slowly to see
if they have been affected by
wat er. If braking performance is
impaired, dry the brakes by apply-
ing them lightly while maintaining
a sl ow forward speed.
