Car Pass The Car Pass contains security
related vehicle data and should
therefore be kept in a safe place.
When the vehicle is taken to a
workshop, this vehicle data is needed
in order to perform certain operations.Radio remote control
Used to operate:
● central locking system 3 24
● load compartment 3 33
● anti-theft locking system 3 35
● anti-theft alarm system 3 36
The remote control has a range of
approx. 5 m. It can be restricted by
external influences. The hazard
warning flashers confirm operation.
Handle with care, protect it from
moisture and high temperatures and
avoid unnecessary operation.
Depending on model, the vehicle may
use a 2-button or 3-button remote
control or an electronic key which
includes the functionality of the
remote control.
Electronic key system 3 21.
Fault
If the central locking system cannot
be operated with the remote control,
it may be due to the following:
● The range is exceeded.
● The battery voltage is too low.
● Frequent, repeated operation of the remote control while not in
range, which will require
reprogramming by a workshop.
● Overload of the central locking system by operating at frequent
intervals; the power supply is
interrupted for a short time.
● Interference from higher-power radio waves from other sources.

Driving and operating131Starting and operating
New vehicle running-in
Do not brake unnecessarily hard for
the first few journeys and after new
disc brake pads have been fitted.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period, fuel and engine oil consumption may be
higher and the cleaning process of
the diesel particle filter may take
place more often. Autostop may be
inhibited to allow for charging the
vehicle battery.
