In rare cases , it may be best to deactivate ESP®(Ypage 66).
XAdapt your driving style to suit the weather and road conditions.
If ESP
®cannot be activated:
XDrive on with care.
XHave ESP®checked at a qualified specialist workshop.
6N The red restraint system warning lamp is lit while the engine is running.
The restraint system is faulty.
GWARNING
The air bags or Emergency Tensioning Devices may either be triggered uninten-
tionally or, in the event of an accident, may not be triggered.
There is an increased risk of injury.
XObserve the display messages.
XDrive on with care.
XHave the restraint system and its components checked immediately at a quali- fied specialist workshop.

;NThe yellow Check Engine warning lamp lights up while the engine is running.
There may be a malfunction, for example:
Rin the engine management
Rin the transmission management
Rin the fuel injection system
Rin the exhaust system
Rin the ignition system (for vehicles with a gasoline engine)
Rin the fuel system
The emission limit values may be exceeded and the engine may be running in
emergency mode.
XHave the vehicle checked as soon as possible at a qualified specialist workshop.
æN The yellow reserve fuel warning lamp is on while the engine is running.
The fuel level has dropped to the reserve range.
XRefuel at the nearest gas station.
?N The red coolant warning lamp comes on while the engine is running.
On vehicles without steering wheel buttons, the coolant temperature gage is at the
start of the bar display (
Ypage 173).
On vehicles with steering wheel buttons, the coolant temperature gage is at the
start of the scale in the instrument cluster (
Ypage 39).
The temperature sensor for the coolant temperature gage is faulty.
The coolant temperature is no longer being monitored. There is a risk of engine
damage if the coolant temperature is too high.
XStop the vehicle immediately, paying attention to road and traffic conditions,
and switch off the engine. Do not continue driving under any circumstances.
XSecure the vehicle to prevent it from rolling away (Ypage 133).
XConsult a qualified specialist workshop.

?NThe red coolant warning lamp comes on while the engine is running.
The coolant level is too low.
If the coolant level is correct, the airflow to the engine radiator may be blocked or
the electric engine radiator fan may be malfunctioning.
The coolant is too hot and the engine is no longer being cooled sufficiently.
XObserve the display messages.
XStop the vehicle immediately, paying attention to road and traffic conditions,
and switch off the engine.
XSecure the vehicle to prevent it from rolling away (Ypage 133).
XExit the vehicle and keep a safe distance from the vehicle until the engine has
cooled down.
XCheck the coolant level and add coolant, observing the warning notes
(Ypage 253).
XIf you have to add coolant more frequently, have the engine cooling system
checked.
XMake sure that the air supply to the radiator is not obstructed, by frozen slush
for example.
XCheck the coolant temperature:
Rusing the display in the on-board computer on vehicles without steering wheel
buttons (Ypage 173)
Rusing the analog display in the instrument cluster on vehicles with steering
wheel buttons (Ypage 39)
XDo not start the engine again until the coolant temperature is below the maxi-
mum value specified below. The engine could otherwise be damaged.
XDrive to the nearest qualified specialist workshop.
Avoid heavy loads on the engine, e.g. driving in mountainous terrain, and stop-
start traffic.
Under normal operating conditions and with the specified coolant level, the cool-
ant temperature gage may rise to 248 ‡ (120 †).
?N The red coolant warning lamp comes on while the engine is running. An addi-
tional warning tone sounds.
The coolant temperature has exceeded the maximum value specified below. The
airflow to the engine radiator may be blocked or the coolant level may be too low.
GWARNING
The engine is not being cooled adequately and could become damaged.
Never drive with an overheated engine. Otherwise, fluids which may have leaked
into the engine compartment could catch fire.
In addition, steam from an overheated engine can cause serious burns, which can
occur just by opening the hood.
There is a risk of injury.
XObserve the display messages.
XStop the vehicle immediately, paying attention to road and traffic conditions,
and switch off the engine.
XSecure the vehicle to prevent it from rolling away (Ypage 133).

hNThe yellow tire pressure monitor warning lamp (pressure loss/malfunction) is lit.
The tire pressure monitor has detected a loss of pressure in at least one of the tires.
GWARNING
Underinflated tires pose the following risks:
RThe tires may burst, especially as the load and vehicle speed increase.
RThe tires may wear excessively and/or unevenly, which may greatly impair tire traction.
RThe handling as well as steering and braking characteristics may be severely
affected.
There is a risk of an accident.
XStop the vehicle without making any sudden steering or braking maneuvers. Pay
attention to the traffic conditions while doing so.
XSecure the vehicle to prevent it from rolling away (Ypage 133).
XObserve the display messages.
XCheck the tires and, if necessary, change the wheel (Ypage 296).
XCheck the tire pressure.
You can check the tire pressure electronically on vehicles with steering wheel
buttons (
Ypage 284).
XIf necessary, correct the tire pressure.
hN The yellow tire pressure monitor (pressure loss/malfunction) warning lamp
flashes for approximately one minute and then remains lit.
The tire pressure monitor is malfunctioning.
GWARNING
The system may not be able to detect or signal low tire pressure as intended.
There is a risk of an accident.
XObserve the display messages.

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.
