The warning light should go out after driving a short distance.
If, after a short drive, the indicator light does not go out, there is a system er-
ror.
Seek help from a specialist garage.
Other incidents
The following reasons can explain the warning light being illuminated.
▶ The vehicle is loaded on one side. Distribute loads as evenly as possible.
▶ The wheels of one axle are loaded more heavily (e.g. when towing a trailer or
when driving uphill or downhill).
▶ Snow chains are mounted.
▶ A wheel has been changed.

Your car is equipped with a central locking system.
The central locking system allows you to lock and unlock all doors and the lug-
gage compartment lid at the same time.
Depending on the equipment configuration, the following applies after un-
locking.
▶ The turn signal lights flash twice as confirmation that the vehicle has been
unlocked.
▶ All the doors and the boot lid are unlocked.
▶ The interior light comes on.
▶ The Safelock system is switched off.
▶ The indicator light in the driver door stops flashing.
Depending on the equipment configuration, the following applies after lock-
ing.
▶ The turn signal lights flash once as confirmation that the vehicle has been
locked.
▶ All the doors and the luggage compartment lid are locked.
▶ The interior lamp goes out.
▶ The Safelock system is switched on.
▶ The warning light in the driver door begins flashing.
If the doors or the luggage compartment lid remain open after the vehicle has
been locked, the turn signal lights do not flash until they have been closed.
Protection against unintended vehicle unlocking
If you unlock the vehicle and do not open a door or the boot lid within the next
30 seconds, the vehicle will lock again automatically and the Safelock system
will be switched on.
Automatic locking/unlocking
All the doors and the luggage compartment lid are locked automatically once
the car reaches a speed of about 15 km/h.
If the ignition key is withdrawn, the car is then automatically unlocked again. It
is also possible for the driver to unlock the car by pressing the central locking
button.
The vehicle doors can be unlocked and opened at any time by pulling once on
the door opening lever.WARNING■ Never leave the key in the vehicle when you exit the vehicle. Unauthor-
ized persons, such as children, for example, could lock the car, turn on the
ignition or start the engine - there is a danger of injury and accidents!■
When leaving the vehicle, never leave persons who are not completely in-
dependent, such as children, unattended in the vehicle. These individuals
might not be able to exit the vehicle by themselves or to help themselves.
Can be fatal at very high or very low temperatures!
CAUTION
■ Each key contains electronic components; therefore it must be protected
against moisture and severe shocks.■
Keep the groove of the keys absolutely clean. Impurities (textile fibres, dust,
etc.) have a negative effect on the functionality of the locking cylinder and ig-
nition lock.
■
If the driver's door has been opened, the vehicle cannot be locked.

the lid is automatically locked after closing. You can set a lock delay
» page 43 .
CAUTION
■
The operation of the remote control may temporarily be affected by signal in-
terference from transmitters close to the car and which operate in the same
frequency range.■
The operating range of the remote control key is approx. 30 m. But this range
of the remote control can be reduced if the batteries are weak.
■
The battery must be replaced if the central locking does react to the remote
control at less than around 3 metres away » page 132.
Note
The remote control will operate only when the vehicle is within sight.
Locking / unlocking the vehicle with the central locking button

Locking
Unlocking
The central locking system also operates if the ignition is switched off.
The following applies after locking. ▶ Opening the doors and the boot lid from the outside is not possible.
▶ The doors can be unlocked and opened from the inside by a single pull on the
opening lever of the respective door.WARNINGDoors locked from the inside make it difficult for rescuers to get into the
vehicle in an emergency – risk to life!
Safe securing system
Read and observe
and on page 39 first.
As soon as the vehicle has been locked from the outside, the Safelock systemprevents the doors from being opened from the inside.
You will be informed that the safelock system has been activated after the ve-
hicle has been locked by means of the message
on the instrument
cluster display.
After locking the vehicle, the warning light in the driver's door flashes for
around 2 seconds in quick succession, afterwards it begins to flash evenly at
longer intervals.
Switching off
▶ The safelock can be switched off by locking twice within 2 seconds.
The indicator light in the driver door flashes for about 2 seconds fast, goes out
and starts to flash at longer intervals after about 30 seconds.
If the vehicle is locked and the safe securing system is switched off, the door
can be opened separately from the inside by a single pull on opening lever.
The Safelock system switches back on when the vehicle is locked.
WARNINGIf the car is locked and the safe securing system activated, no people must
remain in the car as it will then not be possible to either unlock a door or
open a window from the inside. The locked doors make it more difficult for
rescuers to get into the vehicle in an emergency – risk to life!

Central locking fault
If the warning light in the driver's door initially flashes quickly for around 2 sec-
onds, and then illuminates for 30 seconds without interruption before flashing
again slowly, you will need to seek the assistance of a specialist garage.
If there is a fault with the central locking system, only the driver's door can be unlocked or locked with the key. The other doors and the boot lid can be man-
ually locked or unlocked. ▶ Locking the door » page 132.

the door is opened.
42Using the system

WARNING■Never drive with the luggage compartment lid open or ajar, as otherwise
exhaust gases may get into the interior of the vehicle – risk of poisoning!■
Make sure that when closing the boot lid, no body parts are crushed -
there is danger of injury!

Introduction
This chapter contains information on the following subjects:
Mechanical window lifter

Open/close window in the passenger door

Manually opening/closing rear windows
45
The windows can be operated mechanically by the winder attached to the re-
spective door panel.
The windows in the front doors can be operated electrically from the driving
position.
WARNINGThe windows should nevertheless be closed carefully – risk of injury!
CAUTION
■ If windows are frozen, always remove ice » page 98, Windows and external
mirrors before operating the electrical power windows. The window seals and
the electrical power window mechanism can otherwise be damaged.■
Always make sure that the windows are closed when you leave the locked
vehicle.
For the sake of the environment
At high speeds you should keep the windows closed to prevent unnecessarily high fuel consumption.
Note
When driving always use the existing heating, air conditioning and ventilation
system for ventilating the interior of the vehicle. If the windows are open, dust
as well as other dirt can get into the vehicle and in addition the wind noise is
more at certain speeds.43Unlocking and opening

WARNINGBe careful when operating the sliding/tilting roof to avoid crushing injuries
– risk of injury!
CAUTION
During the winter it may be necessary to remove any ice and snow in the vicin-
ity of the sliding/tilting roof before opening it to prevent any damage to the
opening mechanism.
Force limiter
Read and observe
on page 45 first.
The sliding/tilting roof is fitted with a force limiter.
The sliding/tilting roof stops and moves back several centimetres when it can-
not be closed because there is something in the way (e.g. ice).
The sliding/tilting roof only closes without the force limiter activated at the
third attempt at closing. The time interval between the individual closing at-
tempts should not exceed 5 s - the sliding/tilting roof closes with full force! .
Sliding / tilting roof malfunction
Read and observe
on page 45 first.
If the battery has been disconnected and reconnected, it is possible that the
sliding/tilting roof will not operate. The sun roof must be activated.
