complete before driving off.
!Do not activate the EASY-ENTRY/EXIT fea-
ture, if the seat backrest is reclined too far
backwards. This can damage the front or rear

Adjusting the exterior mirrors
GWARNING
The exterior mirror on the front-passenger
side reduces the size of the image. Visible
objects are actually closer than they appear.
This means that you could misjudge the dis-
tance from road users traveling behind, e.g.
when changing lane. There is a risk of an acci-
dent.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder.

cally if the rear window defroster is switched
on and the outside temperature is low.
Folding the exterior mirrors in/out elec-
trically

(15 km/h), you can no longer fold in the exte-
rior mirrors.
Resetting the exterior mirrors
