Opening and closing
Synchronising the vehicle key If the 
button is pr essed fr equently outside
of the vehicle range, it is possible that the ve-
hicle can no longer be locked or unlocked us-
ing the key. In this case, the key must be re-
synchronised as described below:

Operation
When does the system trigger an alarm?
The anti-theft al arm sir
en will be trigger
ed for
about 30 seconds accompanied by sound
and optical (flashing) warning signals and
will be repeated about ten times when the
vehicle is locked and the following unauthor-
ised actions are attempted:

Opening and closing
The vehicle interior monitoring and the anti-
t o
w syst
em are automatically switched on
again next time the vehicle is locked.
The vehicle interior monitoring and anti-tow
sensor (tilt sensor) are automatically switch-
ed on when the anti-theft alarm is switched
on. In order to activate it, all the doors and
the rear lid must be closed.
If you wish to switch off the vehicle interior
monitoring and the anti-tow system, it must
be done each time that the vehicle is locked;
if not, they will be automatically switched on.
The vehicle interior monitoring and the anti-
tow system should be switched off if animals
are left inside the locked vehicle (otherwise,
their movements will trigger the alarm) or
when, for example, the vehicle is transported
or has to be towed with only one axle on the
ground.
False alarms
Interior monitoring will only operate correctly
if the vehicle is completely closed. Please ob-
serve related legal requirements.
The following cases may cause a false
alarm:

Operation

ment) R ear lid aut

ockingWhere the vehicle has been locked by press-
ing the  button on the r
emot

e control with
the rear lid open, the rear lid will lock auto-
matically when closed.
The automatic rear lid locking time extension
function can be activated. Where this func-
tion is activated and once the rear lid has
been unlocked by pressing the 4 button on
the remote control key

Lights and visibility
To ensure the headlight washers work cor-
r ectly in wint
er
, any snow which has got into
the bumper jet supports should be cleaned
away. If necessary, remove snow with an an-
ti-icing spray. Note
The wiper will try to wipe away any obsta-
cles that ar e on the windscr

een. The wiper
will stop moving if the obstacle blocks its
path. Remove the obstacle and switch the
wiper back on again. Rain sensor*

Start and driving
Selector lever lock Fig. 258
Selector lever lock. The selector lever lock prevents gears from
being engaged inadv
ert
ently, so that the v
e-
hicle is not set in motion unintentionally.
The selector lever lock is released as follows:

Start and driving
Since the luggage rack increases the aer o-
dynamic dr ag
of the vehicle, you should re-
move it when not needed. At speeds of
100-120 km/h (62-75 mph), this will save 12%
of fuel.
Save electrical energy
The engine drives the alternator, thereby
generating electricity. This implies that any
increase in power consumption also increa-
ses fuel consumption! For this reason, switch
off any unneeded electrical devices. Devices
that use a lot of electricity includes the blow-
er at a high setting, the rear window heating
or the seat heating*.
Power management
This system helps to ensur
e relia-
ble starting The power management controls the distri-
bution of el
ectrical ener
gy and thus helps t

o
ensure that there is always enough power
available to start the engine.
If a vehicle with a conventional electrical sys-
tem is left parked for a long time, the battery
will gradually lose its charge because certain
electrical devices, such as the electronic
gearbox lock continues to draw current even
when the ignition is off. In some cases there may not be enough power available to start
the engine.
Your v

ehicle is equipped with an intelligent
power management system to control the
distribution of electrical energy. This signifi-
cantly improves reliability when starting the
engine, and also prolongs the useful life of the
battery.
The main functions incorporated in the power
management system are battery diagnosis,
residual current management and dynam-
ic power management.
Battery diagnosis
The battery diagnosis function constantly
registers the condition of the battery. Sensors
detect the battery voltage, battery current
and battery temperature. This enables the
system to calculate the current power level
and charge condition of the battery.
Residual current management
The residual current management reduces
power consumption while the vehicle is
parked. It controls the supply of power to the
various electrical devices while the ignition is
switched off. The system takes the battery di-
agnosis data into consideration.
Depending on the power level of the battery,
switch off the individual electrical devices
one after the other to prevent the battery from losing too much charge and to ensure
that the engine can be started r
eliably.
Dynamic power management
While the vehicle is moving, this function dis-
tributes the available power to the various
electrical devices and systems according to
their requirements. The power management
ensures that on-board systems do not con-
sume more electrical power than the alterna-
tor can supply, and thus maintains the maxi-
mum possible battery power level. Note
