ance to the rear of the vehicle. You could
otherwise lose your balance, e.g. on ice. R
Always ensure that you only make a kicking
movement within the detection range of
sensors :.
R Stand at least 30 cm away from the rear
area while doing so.
R Do not come into contact with the bumper
while making the kicking movement. Oth-
erwise, the sensors may not function cor-
rectly.
R HANDS-FREE ACCESS does not function
when the engine is started.
R If a KEYLESS-GO key is within the rear

behind the vehicle
- polish the rear of the vehicle
Do not carry the KEYLESS-GO key about
your person in such situations. This will
prevent the unintentional opening/closing
of the boot.

WARNING
The exterior mirrors reduce the size of the
image. Objects visible in the mirrors are
closer than they appear. You could misjudge
the distance from road users driving behind
you when changing lanes, for instance. There is a risk of an accident.
You should therefore always look over your
shoulder to determine the actual distance
from road users driving behind you. G
WARNING
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 travelling 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 travelling behind by glancing over your shoulder. X
