should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
! There is a risk of damage to the vehicle if:
R the vehicle becomes stuck, e.g. on a high
curb or an unpaved road
R you drive too fast over an obstacle, e.g. a
curb, speed bumps or a pothole in the road
R a heavy object strikes the underbody or
parts of the chassis
In situations like this, the body, the under-
body, chassis parts, wheels or tires could be
damaged without the damage being visible.
Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no longer withstand the strain they are designed
to.
In such situations, have the vehicle checked
and repaired immediately at a qualified spe-
cialist workshop. If on continuing your jour-
ney you notice that driving safety is impaired, pull over and stop the vehicle immediately,
paying attention to road and traffic condi-
tions. In such cases, consult a qualified spe-
cialist workshop.
Danger of electric shock G
DANGER
The vehicle's high-voltage electrical system is under high voltage. If you modify components
in the vehicle's high-voltage electrical system
or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage is not visible. There is a risk of fatal injury.
Following an accident, do not touch any high- voltage components and never modify the
vehicle's high-voltage electrical system. Have
the vehicle towed away after an accident and
the vehicle's high-voltage electrical system
checked by a qualified specialist workshop. All of the vehicle's high-voltage electrical sys-
tem components are marked with yellow warn-
ing stickers which warn you about high voltages.
The cables of the vehicle's high-voltage electri-
cal system are orange.
When towing a vehicle after an accident, be sure to observe the following sections:
R Transporting the vehicle (Y page 254)
R Towing the vehicle with the front axle raised
(Y page 253)
R Towing a vehicle with both axles on the
ground (Y page 253)
Read the important safety instructions on tow-
ing away (Y page 251).
The ignition must be switched off when carrying out general tasks, such as changing bulbs or
checking the coolant level.
Automatic switching off of the vehicle's high-voltage electrical system If the restraint systems are activated during an
accident, the vehicle's high-voltage electrical
system is automatically deactivated.
This is to ensure that you do not come into con-
tact with high voltage.
Automatic protection from switching
on of the vehicle's high-voltage electri-
cal system The vehicle's high-voltage electrical system is
not activated when the vehicle is started if:
R
a serious electrical insulation malfunction is
detected in the vehicle's high-voltage electri-
cal system
R an electrical connection in the vehicle's high-
voltage electrical system is disconnected Operating safety

tion 0084.
X To switch off: set the switch to the 0033
position.
The interior lighting automatically switches on if you:
R unlock the vehicle
R open a door
R remove the SmartKey from the ignition lock
The interior light is activated for a short while
when the SmartKey is removed from the ignition
lock. This delayed switch-off can be adjusted via
the multimedia system; see the separate oper-
ating instructions. Replacing bulbs
Important safety notes
Xenon bulbs: G
DANGER
Xenon bulbs carry a high voltage. You can get an electric shock if you remove the cover of
the Xenon bulb and touch the electrical con-
tacts. There is a risk of fatal injury.
Never touch the parts or the electrical con-
tacts of the Xenon bulb. Always have work on
the Xenon bulbs carried out at a qualified spe-
cialist workshop.
If your vehicle is equipped with Xenon bulbs, you
can recognize this by the following: the cone of light from the Xenon bulbs moves from the top
to the bottom and back again when you start the
drive system. For this to be observed, the lights must be switched on before the drive system is
started.
Headlamps and lights are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times. Have
the headlamp setting checked regularly.
Other bulbs: G
WARNING
Bulbs, lamps and connectors can get very hot when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before changing a bulb.
Do not use a bulb if it has been dropped or if its glass tube has been scratched.
The bulb may explode if
R you touch it
R it is hot
R you drop it
R you scratch it
Use bulbs only in closed lamps that have been
designed for this purpose. Only install spare
bulbs of the same type and the specified volt-
age.
Marks on the glass tube reduce the service life
of the bulbs. Do not touch the glass tube with
your bare hands. If necessary, clean the glass 90

tube when cold with alcohol or spirit and rub it
off with a lint-free cloth.
Protect bulbs from moisture during operation.
Do not allow bulbs to come into contact with
liquids.
Besides the Xenon bulbs, there are other bulbs
that you cannot replace yourself. Replace only
the bulbs listed (Y page 91). Have the bulbs
that you cannot change yourself replaced at a
qualified specialist workshop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb still does not light up, consult a
qualified specialist workshop.
Headlamps and lights are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times. Have
the headlamp setting checked regularly. Overview of bulb types
