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.

containers. Always keep service products outof the reach of children.
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
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.
Coolant contains glycol and is therefore poison-
ous. Also observe the safety notes under "Ser-
vice products and capacities" (
Ypage 306).
GWARNING
The cooling system is pressurized, particularly
when the motor is warm. If you open the cap,
you could be scalded if hot coolant sprays out.
There is a risk of injury.
Let the engine cool down before you open the
cap. Wear gloves and eye protection. Slowly
open the cap to relieve pressure.
Only check the coolant level and/or fill the cool-
ant if the vehicle is on a level surface and the
engine has cooled down. The coolant tempera-
ture must be below 122 ‡ (50 †).
!Check the engine cooling and heating sys-
tem regularly for leaks.
If a large quantity of coolant is lost, have the
cause traced and rectified at a qualified spe-
cialist workshop.
GWARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.
!Take care not to spill any coolant on painted
surfaces. You could otherwise damage the
paintwork.
Example: cap and coolant expansion tankChecking the coolant level
XStop your vehicle as far away from traffic as
possible on level ground.
XSwitch off the engine.
XSecure the vehicle to prevent it from rolling
away.
XOpen the hood (Ypage 253).
XAllow the engine to cool down.
XUnscrew cap :slowly about half a turn coun-
ter-clockwise and allow excess pressure to
escape.
XTurn cap :further and remove it from cool-
ant expansion tank ;.
XCheck the coolant level.
If the coolant is up to marker bar =in the
filler neck when cold, there is a sufficient
amount of coolant in coolant expansion
tank ;.
If the coolant is approximately 0.59 in
(1.5 cm) above marker bar =in the filler neck
when warm, there is a sufficient amount of
coolant in coolant expansion tank ;.
