Range
The remote control has a range of a few hundred metres when the button cell is fully charged.
Maintain a distanced of at least 2 metres between the remote control and the vehicle.
Avoid any obstacles between the remote control and the vehicle.
Hold the remote control with the aerial Fig. 93pointing vertically upwards.
Do not cover the aerial.
Adverse weather or a weak battery cell will significantly reduce the range.
Renewing the button cell in the remote control
The button cell in the remote control must be replaced if the indicator lamp does not light up.
Insert a suitable object, e.g. a screwdriver, in the recess on the side in the direction of the arrow

First read and observe the introductoryinformation and safety warnings
The electrolyte level of the 12-volt vehicle battery should be checked regularly in high-mileage
vehicles, in hot countries and in older 12-volt vehicle batteries. The 12-volt vehicle battery is
otherwise maintenance-free.
Vehicles with an auxiliary heater Auxiliary heater and ventilationare fitted with special vehicle
batteries. The electrolyte level of these 12-volt vehicle batteries cannot be checked for technical
reasons. Go to a qualified workshop to have the 12-volt vehicle battery checked.

Various indicator lamps may light up after the 12-volt vehicle battery has been connected and the
ignition is switched on. They will go out when you drive a short distance at a speed of approximately
15 20 km/h (10 12 mph). If the indicator lamps remain lit up, the vehicle should be checked by a
qualified workshop.

Automatic switch-off for electrical consumers
The intelligent vehicle electrical system management function automatically implements a range of
measures to prevent the 12-volt vehicle battery from discharging under high loads:


power supply to the 12-volt socket and the cigarette lighter may be interrupted temporarily
while the engine is being started.
The vehicle electrics management system cannot always prevent the 12-volt vehicle battery from
being discharged, for example if the ignition is left on over a long period with the engine off or the
side lights or parking lights are left on over a long period of time.
