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 234.
Note
The remote control will operate only when visual contact with the vehicle.

On vehicles fitted with automatic gearbox, the selector lever must be moved
into the position P before unlocking.
The vehicle cannot be locked from the outside if the ignition has not been
turned off.
After locking the car, it is not possible to unlock within the next 2 seconds by
touching the door handle. This can be used to check whether the vehicle is
locked.
Protection against inadvertently locking the key in the vehicle
If one of the doors is closed after the vehicle has been locked and the key with
which the vehicle was locked remains in the passenger compartment, the ve-
hicle will be automatically unlocked. After unlocking the vehicle again, the turn
signal lights will flash four times. If no door is opened within 45 seconds, the

on the locked vehicle.
▶ Opening the bonnet.
▶ Opening the boot lid.
▶ Opening the doors.
▶ Manipulation of the ignition lock.
▶ Towing the vehicle.
▶ Movement in the vehicle.

Information messages

The START-STOPsystem (hereinafter referred to as the system) reduces
CO 2emissions and harmful emissions, and saves fuel.
If the system determine that the engine is not needed when the vehicle stops
or is at a standstill (e.g. at the traffic lights), it turns off the engine and starts it
again when moving off.
The system function depends on many factors. Some of them are down to the
driver, while others are systemic and can neither be influenced nor identified.
For this reason, the system may react differently in situations which seem
identical from the driver's perspective.
The system is automatically activated every time the ignition is switched on
(even when it has previously been manually deactivated with the
button).
Note
If the engine has stopped due to the system, the ignition remains switched on.130Driving
