Starting and driving
General
Do not overload the battery
The electrical functions in the car load the
battery to varying degrees. Avoid having the
ignition key in position
II when the engine is
turned off. Use position I instead, as less
power is used. The 12 volt outlet in the cargo
area supplies power even when the ignition
key is removed.
Examples of functions that use a lot of power:
• ventilation fan
• windscreen wipers
• audio system
• parking lights
Also take note of different accessories that
load the electrical system. Do not use
functions that consume a lot of current when
the engine is switched off. A text is shown in
the display in the combined instrument panel
if battery voltage is low. The message in the
display remains until the engine has started.
The energy economy function shuts down
certain functions or reduces the load on the
battery, e.g. by lowering ventilation fan speed
and switching off the audio system.
Charge the battery by starting the engine.
Do not allow the engine and
cooling system to overheat
Under certain conditions, e.g. when driving in
hilly terrain and with a heavy load, especially
in warm weather, there is a risk of the engine
and cooling system overheating.
To avoid overheating in the cooling
system:
• Drive at low speeds if driving with a trailer
up a long incline.
• Switch off the air conditioning temporarily.
• Avoid letting the engine idle.
• Do not turn the engine off immediately
you stop, if the car has been driven hard.
• Remove any auxiliary lamps from in front
of the grille if driving in extreme high
temperatures.
To avoid the engine overheating:
Do not exceed engine speeds of 4500 rpm
(diesel engine: 3500 rpm) if driving with a
trailer or caravan in hilly terrain. The oil
temperature can become too high.
