Do not attach heavy or bulky items to the ignition key.
Replacement keys
The key number is specified on the
key or on a detachable tag.
The key number must be quoted
when ordering replacement keys as it
is a component of the immobiliser
system.
If the electronic key needs to be
replaced, the vehicle must be taken to a workshop.

22Keys, 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 26
● load compartment 3 35
● anti-theft locking system 3 37
● anti-theft alarm system 3 38
The remote control has a range of
approx. five 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
remote control.
Electronic key system 3 24.
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.
Manual key operation 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.
Keys, doors and windows25Handsfree operation is automatically
disabled when the electronic key buttons have been operated or the
central locking switch e 3 26 is
pressed. To re-enable handsfree
operation, restart the engine.
Power button 3 131.
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 Driver Information
Centre 3 103.
Battery replacement, see 'Radio
remote control' 3 22.
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
Emergency manual key
Press and hold the release button on
the side of the electronic key and pull out the emergency manual key from
the top.
Manually lock or unlock the doors by turning the key in the lock.
After use, reinsert the emergency
manual key in the housing of the
electronic key.
Door locks Anti-theft security lock
To prevent the doors from being
opened from the outside, open the
driver's door and engage the anti-
theft security lock.
Using a suitable tool, turn the lock
switch on the door to the locked
position. The doors/tailgate cannot be opened from outside.
40Keys, doors and windowsTo silence the alarm siren (if
triggered) and therefore deactivate
the anti-theft alarm system, reconnect vehicle battery and unlock the vehicle
or switch on the ignition.
Immobiliser
The immobiliser 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. two 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 placednear the key when starting the
vehicle.
Note
The immobiliser does not lock the doors. You should always lock the
vehicle after leaving it and switch on the anti-theft alarm system 3 26,
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.
Driving and operating133These functions stop working when
the driver's door is opened and the vehicle is locked.
Note
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 3 104 and a message in the
Driver Information Centre 3 103
when the driver's door is opened.9 Danger
Never leave an electronic key
inside the vehicle when children or animals are left in the vehicle, to
avoid unintended operation of
windows, doors or engine. Risk of
fatal injury.
Fault
If 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 frequentintervals, the power supply is
interrupted for a short time.
● Interference from higher-power radio waves from other sources.

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 3 100.
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 3 135.
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.

186Vehicle careTrailer towing
When towing a trailer with a fully
laden vehicle, the tyre pressure must
be increased by 20 kPa/0.2 bar
(3.0 psi) and the maximum speed
limited to 100 km/h.
Trailer towing 3 161.
Tyre pressure monitoring
system
The tyre pressure monitoring system
uses radio and sensor technology to
check tyre pressure levels.Caution
Tyre pressure monitoring system
warns only about low tyre pressure condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Note
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
The tyre pressure monitoring system
sensors monitor the air pressure in
the tyres and transmit tyre pressure
readings to a receiver located in the
vehicle.
Tyre pressure chart 3 218.
Low tyre pressure conditionA detected low tyre pressure
condition is indicated by illumination
of control indicator w 3 100 and a
corresponding message appears in
the Driver Information Centre.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 218.
After inflating, some driving may be
required to update the tyre pressure
values in the system. During this time
w may illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for
approaching a low tyre pressure
condition. Check tyre pressure of all
four tyres.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise w flashes for
several seconds then illuminates
continuously together with control
indicator F 3 98 and a corresponding
message appears in the Driver
Information Centre.
