Recommendations during driving
05
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.
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. Examples of functions
that use a lot of power:
• ventilation fan
• windscreen wipers
• audio system (high volume)
• parking lamps
If the battery voltage is low, a message ap-
pears on the information display. The energy-
saving function shuts down certain functions
or reduces certain functions such as the ven-
tilation fan and audio system. Charge the
battery by starting the engine.
Before a long journey
• Check that the engine is working normally
and that fuel consumption is normal.
• Make sure that there are no leaks (fuel, oil
or other fluid).
• Check all bulbs and tyre tread depths.
• Carrying a warning triangle is a legal re-
quirement in certain countries.
Winter driving
Check the following in particular before the
cold season:
• The engine coolant must contain at least
50 % glycol. This mixture protects the
engine down to approximately –35 C. To
achieve optimum antifreeze protection,
different types of glycol must not be
mixed.
• The fuel tank must be kept filled to prevent
condensation.
• Engine oil viscosity is important. Oils with
lower viscosity (thinner oils) facilitate start-
ing in cold weather and also reduce fuel
consumption while the engine is cold. For
more information on suitable oils, see
page 218.
• The condition of the battery and charge
level must be inspected. Cold weather
places great demands on the battery and
its capacity is reduced by the cold.
• Use washer fluid to avoid ice forming in
the washer fluid reservoir.
WARNING
Do not drive with the boot lid open. Toxic
exhaust fumes can be drawn into the car
through the cargo area.
IMPORTANT
Low viscosity oil must not be used for hard
driving or in hot weather.
