Display messagesPossible causes/consequences andMSolutions
CheckTirePressureSoonThe tire pressure loss warning system has detected a significant loss
in pressure.
A warning tone also sounds.
Possible causes:
Ryou have changed the positions of the wheels and tires or installed
new wheels and tires.
Rthe tire pressure in one or more tires has dropped significantly
GWARNING
Tire pressures that are too low pose the following hazards:
Rthey may burst, especially as the load and vehicle speed increase.
Rthey may wear excessively and/or unevenly, which may greatly
impair tire traction.
Rthe driving characteristics, as well as steering and braking, may be
greatly impaired.
There is a risk of an accident.
XStop the vehicle without making any sudden steering or braking
maneuvers. Pay attention to the traffic conditions as you do so.
XSecure the vehicle against rolling away (Ypage 145).
XCheck the tires and, if necessary, follow the instructions for a flat
tire (Ypage 306).
XCheck the tire pressures and, if necessary, correct the tire pressure.
XRestart the tire pressure loss warning system when the tire pres-
sure is correct (Ypage 328).
CheckTirePressureThen Restart RunFlat Indicator
The tire pressure loss warning system generated a display message
and has not been restarted since.
XSet the correct tire pressure in all four tires.
XRestart the tire pressure loss warning system (Ypage 328).
Run Flat IndicatorInoperativeThe tire pressure loss warning system is faulty.
XVisit a qualified specialist workshop.
PleaseCorrectTirePressureThe 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 pressures at the next opportunity (Ypage 328).
XIf necessary, correct the tire pressure.
XRestart the tire pressure monitor (Ypage 330).

;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 fuel injection system
Rin the exhaust system
Rin the ignition system (for vehicles with gasoline engines)
Rin the fuel system
The emission limit values may be exceeded and the engine may be in emergency
mode.
XVisit a qualified specialist workshop immediately.
Vehicles with a diesel engine: the fuel tank has been run dry (
Ypage 142).
XStart the engine three to four times after refueling.
If the yellow Check Engine warning lamp goes out, emergency running mode is
canceled. The vehicle need not be checked.
In some states, you must immediately visit a qualified specialist workshop as soon
as the yellow Check Engine warning lamp lights up. This is due to the legal require-
ments in effect in these states. If in doubt, check whether such legal regulations
apply in the state in which you are currently driving.

the electric engine radiator fan may be defective.
The coolant is too hot and the engine is no longer being cooled sufficiently.

XCheck the coolant level and add coolant, observing the warning notes
(Ypage 297).
XIf you have to add coolant frequently, have the engine cooling system checked.
XMake sure that the air supply to the engine radiator is not blocked, e.g. by snow,
slush or ice.
XDo not start the engine again until the coolant temperature is below 248 ‡
(120 †). Otherwise, the engine could be damaged.
XDrive to the nearest qualified specialist workshop.
XAvoid heavy loads on the engine as you do so, e.g. driving in mountainous terrain
and stop-and-go traffic.
?N The red coolant warning lamp comes on while the engine is running.

radiator may be blocked or the coolant level may be too low.
GWARNING
The engine is not being cooled sufficiently and may be damaged.
Do not drive when your engine is overheated. This can cause some fluids which
may have leaked into the engine compartment to catch fire.
Steam from the overheated engine can also cause serious burns which can occur
just by opening the hood.
There is a risk of injury.

Speed alert
You can define the upper speed limit, which
must not be exceeded by the vehicle.
If this selected speed is exceeded by the vehicle,
a message will be sent to the Customer Assis-
tance Center. The Customer Assistance Center
then forwards this information to you.
You can select the way in which you receive this
information beforehand. Possible options
include text message, e-mail or an automated
call.
The data you receive contains the following
information:
Rthe location where the speed limit was excee-
ded
Rthe time at which the speed limit was excee-
ded
Rthe selected speed limit which was exceeded
Geo fencing
Geo fencing allows you to select areas which the
vehicle should not enter or leave. You will be
informed if the vehicle crosses the boundaries
of the selected areas. You can select the way in
which you receive this information beforehand.
Possible options include text message, e-mail or an automated call.
The area can be determined as either a circle or
a polygon with a maximum of ten corners. You
can specify up to ten areas simultaneously. Dif-
ferent settings are possible for each area.
These settings can be called up under "Owners
Online" at http://www.mbusa.com.
Alternatively, you can trigger an MB Info call and
inform the customer service representative that
you wish to activate geo fencing.
Currently inactive areas can be activated by text
message.
Triggering the vehicle alarm
With this function, you can trigger the vehicle's
panic alarm via text message. An alarm sounds
and the exterior lighting flashes. Depending on
the setting, the panic alarm lasts five or ten sec-onds. Afterwards, the alarm switches off.
