Electrical equipment can be connected to the socket in the vehicle.
Connected equipment must be in perfect condition and show no signs of
faults.
Additional information and warnings:
● Cigarette lighter ⇒ page 115
● Accessories, parts replacement, repairs and modifications ⇒ page 222
WARNING
Improper use of the socket or electrical devices could lead to a fire and
cause serious injuries.
● Never leave children unsupervised in the vehicle. The socket and
equipment connected to it can be used when the ignition is switched on.
● Should a connected electrical device overheat, switch it off and un-
plug it immediately.
CAUTION
● To avoid damage to the vehicle's electrical system, never connect equip-
ment that generates electrical current, such as solar panels or battery charg-
ers, to the 12 Volt sockets in order to charge the vehicle's battery.
● Only use accessories with approved electromagnetic compatibility ac-
cording to current regulations. ●
To avoid damage due to voltage variations, switch off all appliances con-
nected to the 12 V socket before switching the ignition on or off and before
starting the engine.
● Never connect an appliance to the 12 Volt socket that consumes more
than the power indicated in watts. Exceeding the maximum power absorp-
tion could damage the vehicle's electrical system.
For the sake of the environment
Do not leave the engine running when the vehicle is at a standstill.
Note
Using electrical appliances with the engine stopped and the ignition switch-
ed on will drain the battery.
Note
Unshielded equipment can cause interference on the radio system equip-
ment and the vehicle's electrical system.
Note
If electrical equipment is used near an aerial, you may observe interference
in the reception of AM stations. 

Steering Introduction
The power steering* is not hydraulic but electromechanical. The advantage
of this steering system is that it disposes of hydraulic tubes, hydraulic oil,
the pump, filter and other components. The electromechanical system
saves fuel. While a hydraulic system requires oil pressure to be maintained,
electromechanical steering only requires energy when the steering wheel is
turned.
With the electromechanical steering system, the power steering function au-
tomatically adjusts according to the vehicle speed, the steering torque and
the wheel turning angle. The electromechanical steering only works when
the engine is running.
Additional information and warnings:
● Start and stop the engine ⇒ page 119
● Vehicle battery ⇒ page 193
● Tow-starting and towing away ⇒ page 276
WARNING
If the power steering is not working then the steering wheel is much
more difficult to turn and the vehicle more difficult to control.
● The power steering only works when the engine is running.
● Never allow the vehicle to move when the engine is switched off.
● Never remove the key from the ignition if the vehicle is in motion. The
steering may lock and it will not be possible to turn the steering wheel.
