Keys, doors and windows23Car 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
● anti-theft locking system
● anti-theft alarm system
Depending on model, the vehicle may use a 2-button or 3-button remote
control.
The remote control has a range of
approx. 5 m. It can be affected by
external influences. The hazard
warning flashers confirm operation.
Handle with care, protect it from
moisture and high temperatures and
avoid unnecessary operation.
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.Unlocking 3 26.
Remote control battery
replacement
Replace the battery as soon as the
range reduces.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.

compartment by inserting a coin into
the slot and twisting.
Replace the battery (battery type
CR2016), paying attention to the
installation position.
Reattach both halves of cover
ensuring it engages correctly.
Replace screw and tighten.
Electronic key system
Enables a hands-free operation of thecentral locking system 3 26.
The electronic key simply needs to be on the driver's person.
Note
Always take the electronic key with
you when exiting the vehicle.
For hands-free operation, the
electronic key must be outside the
vehicle, within a range of approx.
1 m of the front doors or load
compartment.
Hands-free operation is automatically
disabled when the central locking
switch e 3 26 is pressed. To re-
enable hands-free operation, restart
the engine.
Electronic key battery
replacement
Replace the battery as soon as the
system no longer operates properly
or the range is reduced.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.

Keys, doors and windows25Open battery compartment by
inserting a coin into the slot and
twisting.
Replace the battery (battery type
CR2016), paying attention to the
installation position.
Note
Do not touch the electronic circuit in
the cover when replacing the
battery.
Reattach both halves of cover
ensuring it engages correctly.
Fault
If the central locking system cannot
be operated or the engine cannot be
started, the cause may be one of the
following:
● fault in electronic key
● electronic key out of reception range
● battery voltage too low● 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
Door locks Anti-theft security lock
To prevent the front doors from beingopened from the outside, open the
door and engage the anti-theft
security lock.
Using a suitable tool, turn the lock
switch on the door to the horizontal locked position. The door cannot be

opened from inside the vehicle or by
using the manual key.
To disengage, turn the switch to the
unlocked position.
Manual door locks
To unlock the front doors manually,
turn the key in the driver's door lock.
Open the front doors by pulling the handles.

or close the door fully until it
latches into its locking position.
Keep a close watch on the moving door when operating. Ensure thatnothing becomes trapped during
operation and no-one is standing
within the moving area.
Note

Keys, doors and windows39Electronic key
For hands-free operation, the
electronic key must be outside the
vehicle, within a range of approx.
1 m of the front doors or load
compartment.
Press the button on any exterior door
handle.
Electronic key system 3 24.
Deactivation
Unlocking the vehicle or switching on the ignition deactivates the anti-theft
alarm system. Hazard warning lights
flash once to confirm deactivation.
Note
If the alarm has been triggered,
unlocking the vehicle with the key
will not stop the alarm siren. To stop the siren, switch on the ignition. The
hazard warning lights will not flash
upon deactivation if the alarm has
been triggered.
Activation without monitoring of
passenger compartment
Switch off monitoring of the
passenger compartment when
people or animals are being left in the
vehicle, or if the auxiliary heater
3 127 is set for a timed or remote
controlled start.Depending on vehicle configuration:
● press and hold e, or
● switch ignition on and off twice quickly, then close doors and
activate the anti-theft alarm
system
An audible signal will sound as
confirmation.
The status will remain until the doors
are unlocked.
Alarm When triggered, the alarm sounds via a separate battery-backed power
sounder, and the hazard warning
lights flash simultaneously. The
number and duration of alarm signals
are stipulated by legislation.
If the vehicle battery is disconnected
or its power supply is interrupted, the
alarm siren will be triggered. First
deactivate the anti-theft alarm system if the vehicle battery must be
disconnected.
To silence the alarm siren (if
triggered) and therefore deactivate
the anti-theft alarm system, reconnect

Immobiliser
The system is part of the ignition
switch and checks whether the
vehicle is allowed to be started with
the key being used.
The immobiliser is activated
automatically after the key has been
removed from the ignition switch and
also if the key is left in the ignition
switch when the engine is turned off.
If the engine cannot be started, switch off the ignition and remove key, wait
approx. 2 seconds and then repeat
the start attempt. If start attempt is
unsuccessful, attempt to start the
engine using the spare key and seek
the assistance of a workshop.
Note
Radio Frequency Identification
(RFID) tags may cause interference
with the key. Do not have it placed near the key when starting the
vehicle.Note
The immobiliser does not lock the doors. Always lock the vehicle after
leaving it 3 26 and switch on the anti-
theft alarm system 3 38.Exterior mirrors
Convex shape The convex exterior mirror contains
an aspherical area and reduces blind spots. The shape of the mirror makes
objects appear smaller, which will
affect the ability to estimate
distances.
Manual adjustment
Adjust mirrors by swivelling in
required direction.
The lower mirrors are not adjustable.

138Driving and operatingCaution
Vehicles equipped with hydraulic
power steering:
If the steering wheel is turned until it reaches the end of its travel, and
is held in that position for more
than 15 seconds, damage may
occur to the power steering
system and there may be loss of
power steering assist.
Starting 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.
Stop-start system 3 140.
Diesel particle filter 3 146.
