An automotive glass cleaner is recom-
mended.
!Do not apply strong pressure to the
sensor covers. Applying strong pres-
sure may damage the sensor covers.
Follow the instructions provided by the
power washer manufacturer on main-
taining a distance between the vehicle
and the nozzle of the power washer.!To prevent scratches, never apply
strong force and only use a soft,
non-scratching cloth when cleaning the
sensors. Do not attempt to wipe dirty
sensors with a dry cloth or sponge.
Warning!
G
For safety reasons, switch off wipers and re-
move SmartKey from starter switch
(vehicles with KEYLESS-GO*: Make sure the

touch the inside of the front, rear or
side windows with hard objects such as
an ice scraper or ring. Doing so may
