The lights in the footwell area below the dash (driver and front passenger
sides) will switch on when the doors are opened and will decrease in inten-
sity while driving. The intensity of these lights can be adjusted using the ra-
dio menu (see Easy Connect > Adjusting Lighting > Interior lighting⇒ page 81).

Sun visors
Fig. 63 Sun visor
Options for adjusting driver and front passenger sun visors:
● Lower by unfolding towards the windscreen.

door ⇒ Fig. 63 1
.
● Swing the sun visor towards the door, longitudinally backwards.
Vanity mirror light
There may be a vanity mirror, with a cover, on the rear of the sun visor. When
the cover is opened 2
a light comes on.
The lamp goes out when the vanity mirror cover is closed or the sun visor is
pushed back up.
Note
The light above the sun visor automatically switches off after a few minutes
in certain conditions. This prevents the battery from discharging. Windscreen wiper system
Introduction
Additional information and warnings:
● Changing wheels round
● Heating, ventilation, cooling
● Caring for and cleaning the vehicle exterior
WARNING
If the water from the windscreen washer does not contain enough anti-
freeze, it may freeze on the windscreen, reducing forward visibility.
● In winter, ensure the windscreen washer contains enough anti-freeze.
● In cold conditions, you should not use the wash/wipe system unless
you have warmed the windscreen with the ventilation system. The anti-
freeze could freeze on the windscreen and reduce visibility.
WARNING
Worn or dirty wiper blades reduce visibility and increase the risk of acci-
dent and serious injury.
● Always replace damaged or worn blades or blades which do not clean
the windscreen correctly.
CAUTION
In icy conditions, always check that the wiper blades are not frozen to the
glass before using the wipers. In cold weather, it may help to leave the vehi-
cle parked with the wipers in service position ⇒ page 119. 

Checking and refilling levels
Charging the battery
Terminals for charging the battery are fitted in the engine
compartment.
– Note the warnings ⇒ 
in Important safety warnings for han-
dling a vehicle battery on page 218 and ⇒ .
– Switch off all electrical equipment. Remove the ignition key.
– Raise the bonnet ⇒ page 210.
– Open the battery cover.
– Connect the charger clamps as described to the positive pole of
the battery (+) and, exclusively to an earth on the bodywork
(–).
– Only use a charger which is compatible for use with 12 V nomi-
nal voltage batteries. The charge must not exceed a voltage of
15 V.
– Now connect the battery charger to the power socket and switch
on.
– After charging the battery: switch off the battery charger and
disconnect the power socket cable.
– Finally disconnect the charger cables from the battery.
– Replace the battery cover correctly.
– Close the bonnet ⇒ page 210.
Important: Before you charge the battery make sure you read the manufac-
turer's instructions for using the battery charger.
WARNING
Never charge a battery that has frozen: replace battery! Failure to do so
may lead to an explosion.
Note
Use only the terminals in the engine compartment to charge the battery. 
Replacing the battery
The new battery should have the same specifications (am-
perage, load and voltage) as the used battery.
Your vehicle is equipped with an intelligent power management system to
control the distribution of electrical energy ⇒ page 187. The power manage-
ment function ensures that the battery is charged much more efficiently
than on vehicles without a power management system. To maintain this
function after replacing the battery, we recommend that the replacement
battery used is of the same make and type as the original fitted battery. To
make proper use of the power management function after the battery has
been changed, have the battery coded to the power management mode at a
specialised workshop.
CAUTION
● Some vehicles, for example those with the Start-Stop system* are fitted
with a special battery (AGM-type or EFB-type battery). If any other type of
battery is fitted, the Start-Stop function may be considerably reduced and
the vehicle may not stop on repeated occasions.
● Make sure that the vent hose is always attached to the original opening
on the side of the battery. Gases or battery acid can otherwise escape and
possibly cause damage.
● The battery holder and clamps must always be correctly secured. 
