NOTICE
If you park your vehicle near a stainless
steel sign or glass facade building, the
vehicle’s exterior plastic parts such
as a bumper, spoiler, garnish, lamp
or outside rearview mirror might be
damaged due to sunlight reflected
from the sign or building. To prevent
damage of the exterior plastic parts,
you should avoid parking in areas
where light may be reflected or use a
car cover. (The exterior plastic parts
applied to your vehicle may vary.)
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.
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
thoroughly with lukewarm or cold water.
Do not allow soap to dry on the finish.
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 and lamps, do not clean
with chemical solvents or strong
detergents.
