Maintenance
High-pressure washing
When using high-pressure wash-
ers, make sure to maintain suffi-
cient 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 oper-
ate normally.
Do not bring the nozzle tip close to
boots (rubber or plastic covers) or
connectors as they may be dam-
aged if they come into contact with
high pressure water.
ODEP079071L
CAUTION - Wet engine
Water washing in the engine
compartment including high
pressure water washing may
cause the failure of electrical
circuits located in the engine
compartment.
Never allow water or other liq-
uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as
this may damage them.
(Continued)
(Continued)
To prevent damage to the
charging door, make sure to
close and lock the vehicle
doors when washing (high-
pressure washing, automatic
car washing, etc.) the vehicle.
