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.
High-pressure washing
• When using high-pressure washers, make sure to maintain sufficient
distance 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 applied
from 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.
• Do not use any high-pressure nozzles, which induce either one-direct water
stream or water swirling.
Protecting your vehicle’s finish
Washing
To help protect your vehicle’s finish from
rus
t 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, should be used.
After washing, rinse the vehicle
thoroughly with lukewarm or cold water.
Do not allow soap to dry on the finish.
WARNING
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 forward speed.
NOTICE
• Do not use strong soap, chemical
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, do not clean with chemical
solvents or strong detergents.
APPEARANCE CARE

Repairing your vehicle’s finish
Deep scratches or stone chips in the
painted surface must be repaired
promptly. Exposed metal will quickly
rust and may develop into a major repair
expense.
NOTICE
If your vehicle is damaged and requires
any metal repair or replacement,
be sure the body shop applies anti-
corrosion materials to the parts
repaired or replaced.
NOTICE
Matte paint finish vehicle (if equipped)
In case of matte paint finish vehicles,
it is impossible to modify only the
damaged area and repair of the whole
part is necessary. If the vehicle is
damaged and painting is required,
we recommend that you have your
vehicle maintained and repaired by
an authorized HYUNDAI dealer. Take
extreme care, as it is difficult to restore
the quality after the repair.
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
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, 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. 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.
WARNING
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 forward
speed.
Aluminum wheel maintenance
The aluminum wheels are coated with a
clear protective finish.
