foot brake. The vehicle will creep forward even when the engine is idling, as power transmission is
even then not fully interrupted.
Never select reverse or selector lever position P when the vehicle is in motion.
Never leave the vehicle in selector lever position N. The vehicle will roll downhill irrespective of
whether or not the engine is running.

NOTICE
If the electronic parking brake is not switched on when the vehicle is stationary and the brake pedal
is released when the selector lever is in position P, the vehicle may move a few centimetres forwards
or backwards.

If the lever is moved accidentally to N when driving, take your foot off the accelerator. Wait for the
engine to reach idling speed in the neutral position before selecting a position again.

If the selector lever is left in any position other than P for long periods when the engine is switched
off, the 12-volt vehicle battery will discharge.

Electrical sockets
Introduction
This chapter contains information on the followingsubjects:
⇒ Electrical sockets in the vehicle 
Electrical equipment can be connected to the sockets in the vehicle.
The electrical devices must be in good condition. Do not use faulty devices.
The 12-volt socket will work only when the ignition is switched on.

WARNING
Improper use of the sockets and electrical accessories can cause fires and severe injuries.
Never leave children unsupervised in the vehicle. Sockets and the devices connected to them can be
used when the ignition is switched on.
If the electrical device gets too hot, switch off the device immediately and disconnect it from the
socket.

NOTICE
In order to prevent damage to the electrical system, never connect equipment that supplies electric
power, such as solar panels or battery chargers for charging the 12-volt battery, to the 12-volt
socket.
Use only electrical devices that have been approved in accordance with current guidelines
concerning electromagnetic compatibility.
In order to avoid damage due to voltage fluctuations, always switch off any electrical devices before
switching the ignition on or off and before starting the engine. When the start/stop system

automatically switches off and restarts the engine, it is not necessary to switch off any connected
electrical consumers.
Never connect electrical devices requiring more than the rated power to a 12-volt socket. The
vehicle's electrical system can be damaged if the maximum power consumption is exceeded.
