20Keys, doors and windowsCar 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 23
● anti-theft locking system 3 33
● anti-theft alarm system 3 35
● load compartment 3 32
The remote control has a range of
approx. 5 metres. 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 radio
remote control.
Electronic key system 3 22.
Fault
If the central locking system cannot
be operated with the remote control,
it may be due to the following:
● range exceeded
● battery voltage 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
Manual key operation 3 23.
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.
Keys, doors and windows212-button and 3-button remote control
Remove screw and open battery
compartment by inserting a coin into
the slot and twisting.
Replace the battery (battery type
CR 2016), paying attention to the
installation position.
Reattach both halves of the cover,
ensuring they engage correctly.
Replace screw and tighten.
Electronic key
The need for battery replacement is
indicated by a message in the Driver
Information Centre (DIC) 3 91.
Press and hold the release button on
the side of the electronic key and pull out the emergency manual key from
the top. Unclip the battery cover
located on the rear of the electronic
key, then press one side of the battery
to release and remove the battery.
Replace the battery (battery type
CR 2016), paying attention to the
installation position.
Reattach battery cover and reinsert
the emergency manual key.
Electronic key synchronisation
Press any button on the electronic
key four times within range of the
detection zone (approx. one metre) of the front doors or load compartment.
The electronic key will be
synchronised when the ignition is
switched on.
22Keys, doors and windowsElectronic key system
Enables a handsfree operation of thefollowing functions:
● central locking system 3 23
● load compartment 3 32
● ignition switching on and starting the engine 3 116
The electronic key simply needs to be on the driver's person.
Notice
Always take the electronic key with
you when exiting the vehicle.
The electronic key being left in the
card reader is indicated by a warning
chime 3 92 and a message in the
Driver Information Centre (DIC)
3 91 when the driver's door is
opened.
Additionally, the electronic key
includes the functionality of the radio
remote control 3 20 and an entry
lighting function 3 101.
Handle with care, protect from
moisture and high temperatures and
avoid unnecessary operation.
Notice
Do not put the electronic key in the
load compartment during driving, as
this is outside of the detection zone
(indicated by a warning chime at low
speed 3 92 and a message in the
Driver Information Centre (DIC)
3 91).
Handsfree operation is automatically disabled when the electronic key
buttons have been operated or the
central locking switch e 3 23 is
pressed. To re-enable handsfree
operation, restart the engine.
Power button 3 116.Replacing battery in electronic
key
Replace the battery as soon as the
system no longer operates properly
or the range is reduced. The need for
battery replacement is indicated by a
message in the DIC 3 91.
Battery replacement, see Radio
remote control 3 20.
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
110Climate control
In addition to a remote control unit,
the heating can also be switched on
for 30 minutes, or off, using the button
on the instrument panel.
Battery replacement
Replace the battery when the range
of the remote control is reduced or when the battery charge symbol
flashes.
Open the cover and replace the
battery (Type A: CR 2430, Type B: 2CR 11108, or equivalent), ensuring
the new battery is correctly installed
with the positive ( <) side facing the
positive terminals. Replace the cover
securely.
Dispose of old batteries in
accordance with environmental
regulations.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.

remote control, select Add and
confirm.
AddE teaches the current remote
control unit exclusively and blocks all
previously configured units. Add
teaches up to 4 remote control units,
but only one unit can operate the
system at any one time.
Operation
Heating Y
Press Y, the predetermined heating
duration, e.g. 30 is displayed.
To temporarily adjust the heating duration, adjust with k or l. The
value can be set from 10 to
120 minutes. Due to the power
consumption, note the heating
duration.
To switch off, press Y.
118Driving and operating● Battery voltage too low.
● Overload of the central locking system by operating at frequentintervals, the power supply is
interrupted for a short time.
● Interference from higher-power radio waves from other sources.
Battery replacement 3 20.
Central locking system 3 23.
Electronic key system 3 22.
Starting the engine
Manual transmission: operate clutch.
Do not accelerate.
Diesel engines: turn the key to
position 2 for preheating until control
indicator ! extinguishes in the
instrument cluster 3 88.
Turn key to position 3 and release.
The increased engine speed
automatically returns to normal idling
speed as the engine temperature
rises.
Start attempts should not last longer
than 15 seconds. If engine does not
start, wait 15 seconds before
repeating starting procedure. If
necessary, depress accelerator
before repeating starting procedure.
Before restarting or to switch off the
engine, turn key back to 0.
During an Autostop, the engine can
be started by depressing the clutch
pedal. Stop-start system 3 119.
Turbo engine warm-up Upon start-up, engine available
torque may be limited for a short time,
especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully protect the engine.Idle speed control
To increase the idle speed, press theswitch. After a few seconds the
function will be activated.
The function will be deactivated
when:
● The clutch pedal is depressed.
● The accelerator pedal is depressed.
● Vehicle speed is above 0 mph.
● Control indicator F, W or C
illuminate in the instrument
cluster.
To increase or decrease the fast idle
speed rate, consult a workshop.
