Always ensure that you only make the kick-
ing movement within the detection range of
sensors 0043.
R Stand at least 12 in (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

Do not carry the KEYLESS-GO key about
your person in these situations or in situa-
tions similar to these. This will prevent the
unintentional opening/closing of the trunk.

may restrict functionality.
R Using the HANDS-FREE ACCESS with a
prosthetic leg may restrict functionality. Operation X

Vehicles with a rain sensor: in the0062or
0063 position, the appropriate wiping fre-
quency is automatically set according to the
intensity of the rain. In the 0063position, the
rain sensor is more sensitive than in the 0062
position, causing the windshield wipers to
wipe more frequently.
If the wiper blades are worn, the windshield
will no longer be wiped properly. This could
prevent you from observing the traffic condi-
tions. Replacing the wiper blades
Important safety notes G

the windshield wiper arm without a wiper
blade and it falls onto the windshield, the
windshield may be damaged by the force of
the impact.

Start/Stop button General notes
A check which periodically establishes a radio
connection between the vehicle and the
SmartKey determines whether a valid Smart- Key is in the vehicle. This occurs, for example, when starting the engine.
To start the vehicle without actively using the
SmartKey:
R the Start/Stop button must be inserted in
the ignition lock.
R the SmartKey must be in the vehicle.
R the vehicle must not be locked with the
SmartKey or KEYLESS-GO (Y page 81).
Pressing the Start/Stop button several times
in succession corresponds to the different
SmartKey positions in the ignition lock. This is
only the case if you are not depressing the
brake pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi- ately.
Do not keep the SmartKey:
R with electronic devices, e.g. a mobile
phone or another SmartKey
R with metallic objects, e.g. coins or metal
foil
R inside metallic objects, e.g. a metal case
