Engine revolutions counter
The tachometer
1
» Fig. 20 on page 32 shows the actual engine speed per
minute.
The beginning of the tachometer red scale range indicates the maximum per-
mitted speed for an engine that has been driven-in and has reached operating
temperature.
You should shift into the next highest gear before the red scale of the revolu-
tion counter is reached, or select mode D / S on the automatic gearbox.
The gear recommendation is important to note in order to maintain the opti-
mum engine speed » page 44.
CAUTION
The pointer of the engine revolutions counter must reach the red area for only
a short time - there is a risk of engine damage!

yond the effective range of the system or the battery in the remote control key
has been replaced and the vehicle cannot be unlocked using the remote con-
trol, the key must be synchronised.

the button.
Fault with the central locking
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.
A fault in the central locking system means the vehicle doors and the boot lid
cannot be emergency locked or emergency unlocked » page 302.
Failure of the system KESSY
If there is a fault in the KESSY system, the appropriate error message is dis-
played in the instrument cluster.
Low voltage of the key battery
If the voltage of the key battery is too low, a message appears in the display of

Anti-theft alarm system
Introduction
This chapter contains information on the following subjects:
Alarm trigger
57
Interior monitor and towing protection
58The alarm system triggers audible and visual signals if an attempt is made to
break into the vehicle (hereafter referred to as alarm).
The alarm system is activated automatically approximately 30 seconds after
the vehicle is locked. This is automatically disabled after release.
CAUTION
Before leaving the vehicle, it must be checked that all of the windows, doors
and the sliding/tilting roof are locked in order to ensure the full functionality of
the anti-theft alarm system.
Note
The alarm system has its own power source, the service life of which is 5 years.
In order to ensure functionality of the alarm system, we recommend that you
get the alarm checked after this time by a specialist garage.
Alarm trigger
Read and observe
on page 57 first.
The alarm is triggered when one of the following unauthorised actions is acti-
vated on the vehicle with an activated warning system. ▶ Opening the bonnet.
▶ Opening the boot lid.
▶ Opening the doors.
▶ Manipulation of the ignition lock.
▶ Towing the vehicle.
▶ Movement in the vehicle.
▶ Sudden and significant voltage drop of the electrical system.
▶ Uncoupling the trailer.
An alarm is triggered also when the driver's door is unlocked and opened by
the lock cylinder.
The alarm is switched off by pressing the
button on the key or switching on
the ignition.
57Unlocking and opening

WARNINGDo not use the windscreen washer system at low temperatures, without
heating the windscreen beforehand. The window washer fluid could other-
wise freeze on the windscreen and restrict the view to the front.
CAUTION
■ If the windscreen wipers are in rest position, they cannot be folded out from
the windscreen. The wipers must be set to the service position to raise them
off the windscreen » page 304.■
In cold temperatures and during the winter, check before switching on the
ignition that the wiper blades are not frozen to the windscreen. If the wind-
screen wipers are switched on when the blades are frozen to the windscreen,
this may damage both the blades and windscreen wiper motor.
■
Carefully release the frozen-on windscreen wiper blades from the wind-
screen and remove snow and ice.
■
Handle the windscreen wipers with care - there is the risk of damaging the
windscreen with the windscreen wiper arms.
■
Do not switch on the ignition when the front windscreen wiper arms are fol-
ded down - there is the danger of damaging the bonnet by the windscreen
wiper arms.
■
If there is an obstacle on the windscreen, the wipers will try to push away
the obstacle five times. Thereafter, the wipers will stop to prevent them be-
coming damaged. Turn on the wipers again only after the obstacle has been
removed.
Note
■ Each time the ignition switches off for the third time, the position of the
windscreen wipers changes. This counteracts an early fatigue of the wiper
blades.■
The windscreen washer nozzles for the windscreen are heated when the en-
gine is running and the outside temperature is less than +10 °C.

At a speed of more than 2 km/h, the wiper wipes once again 5 seconds after
the last wiper stroke in order to wipe the last drops from the windscreen. This
function can be activated/deactivated by a specialist garage.
