AdjustTirePressureThe tire pressure is too low in at least one of the tires, or the tire
pressure difference between the wheels is too great.
XCheck the tire pressure at the next opportunity (Ypage 286).
XIf necessary, correct the tire pressure.
XRestart the tire pressure monitor (Ypage 289).
Check TiresAn additional warning tone sounds.
The tire pressure in one or more tires has dropped significantly. The
display shows the wheel position.
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 135).
XCheck the tires and, if necessary, change the wheel (Ypage 298).
XCheck the tire pressure (Ypage 286).
XIf necessary, correct the tire pressure.
Warning Tire Mal‐functionThe tire pressure in one or more tires has dropped suddenly. The dis-
play shows the wheel position.
GWARNING
Driving with a flat tire poses a risk of the following hazards:
RA flat tire affects the ability to steer or brake the vehicle.
RYou could then lose control of the vehicle.
RContinued driving with a flat tire will cause excessive heat build-up
and possibly a fire.
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 135).
XCheck the tires and, if necessary, change the wheel (Ypage 298).
Tire Pressure Moni‐tor CurrentlyUnavailable
Due to a source of radio interference, no signals can be received from
the wheel sensors. The tire pressure monitor is temporarily malfunc-
tioning.
The tire pressure monitor restarts automatically as soon as the prob-
lem has been solved.

òN$ (USA only) or J(Canada only): the ABS and brake warning lamps are
lit while the engine is running.
EBD is unavailable due to a malfunction. ABS, BAS, hill start assist and ESP
®as well
as its driving safety systems, for example, are therefore also unavailable.
ATTENTION ASSIST is deactivated and other driving systems could be automati-
cally deactivated.
GWARNING
The brake system continues to function normally, but without the functions listed
above. The wheels could therefore lock prematurely if you brake hard, for example.
This causes steerability and braking to be greatly impaired. The braking distance
may increase in emergency braking situations.
If ESP
®is not operational, ESP®will not stabilize the vehicle.
There is an increased risk of skidding and accidents.
XSwitch the engine off, wait briefly and start the engine again.
XCheck if the display message has disappeared and ESP®is operational.
XIf the display message continues to be displayed:

;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 175).
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 135).

?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 135).
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 255).
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 175)
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 135).
