Important safety notes
GWARNING
If you operate information systems and com-
munication equipment integrated in the veh i-
cle while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traff icconditions and operate the equip-
ment when the vehicle isstationary.
Observe the legal requirements for the country
you are in.
The multimedia system calculates the route to
the destination without taking account of the
following, for example:
Rtraff iclights
Rstop and giveway signs
Rparking or stopping restrictions
Rroad narrowing
Rother road and traffic rules and regulations
The multimedia system may provide incorrect
navigation announcements if the surroundings
do not correspond to the data on the digital
map. For example, a route may have been diver-
ted or the direction of a one-way street may have
changed.
For this reason, you must always observe road
and traffic rules and regulations during your
jo urney. Road and traffic rules and regulations
always have priority over the system's driving
recommendations.

well as standard and optional equipment of your
vehicle that were available at the time of going
to print. Country-specific variations are possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.

Engine compartment
Hood
Important safety notes
GWARNING
If the hood is unlatched, it may open up when the vehicle is in motion and block your view.
There is a risk of an accident.
Never unlatch the hood while driving. Before
every trip, ensure that the hood is locked.
GWARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
GWARNING
The engine compartment contains moving
components. Certain components, such as
the radiator fan, may continue to run or start
again suddenly when the ignition is off. There is a risk of injury.
If you need to do any work inside the engine
compartment:
Rswitch off the ignition
Rnever reach into the area where there is a
risk of danger from moving components,
such as the fan rotation area
Rremove jewelry and watches
Rkeep items of clothing and hair, for exam-
ple, away from moving parts
GWARNING
The ignition system operates with a high volt- age. If you touch the live components, you
could receive an electric shock. There is an
increased risk of injury.
Never touch components of the ignition sys-
tem if:
Rthe engine is running or being started
Rthe key is in radio position or drive position
in the ignition lock
The live components of the ignition system are,
for example:
Rignition coils
Rspark plug connectors
Rdiagnostic sockets
GWARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following.
If you have to carry out work in the engine com-
partment, only touch the following components:
Rhood
Roil dipstick
Rengine oil filler neck cap
Rwasher fluid reservoir cap
Rcoolant expansion tank cap
