your distance from the vehicles behind you
when changing lanes, wh ich increases the risk
of an accident.
(D Note
- If the mirror housing was moved by outs ide
forces (such as an impact when maneuver­ in g), you must use the power fold ing func­
tion to fold the mirror all the way out. The
mirror housing must not be moved back in­
to place by hand because this would impair
the function of the m irror mechanism.
- If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in

breaths immediately after leaving the vehi­
cle or, if this is not possible, open all of the
doors and w indows as wide as possible.
- If electrolyte fluid enters the eyes, flush
them thoroughly with a large amount of
