Clean the electric contacts of the electric en-
gine block heater and trailer coupling after
driving in water and mud. Do not overload the battery
The electrical functions in the car load the
battery to varying degrees. Avoid using the
ignition position II when the engine is
switched off. Use ignition position I instead,
as less power is consumed.
The 12 volt outlet in the cargo area supplies
power even when the ignition key is re-
moved.
Examples of functions that use a lot of pow-
er:
• ventilation fan
• windscreen wipers
• audio equipment (high volume)
• parking lamps
Also, be aware of different accessories that
load the electrical system. Do not use func-
tions which use a lot of power when the en-
gine is switched off.
If the battery voltage is low, a message ap-
pears on the display. The energy-saving
function shuts down certain functions or re-
duces the load on the battery by, for exam-
ple, slowing the ventilation fan and switching
off the audio equipment. Charge the battery
by starting the engine.
IMPORTANT
Do not let the car stand with water over the
sills for any long period of time. This could
cause electrical malfunctions.
In the event of stalling in water, do not try to
restart. Tow the car out of the water.
