APPEARANCE CARE
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
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, should be used.
After washing, rinse the vehicle
thoroughly with lukewarm or cold water.
Do not allow soap to dry on the finish.
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.
