The restraint system is faulty.
GWARNING
The air bags or Emergency Tensioning Devices may either be trig-
gered unintentionally or, in the event of an accident, may not be
triggered.
There is an increased risk of injury.
XDrive on carefully.
XHave the restraint system checked at a qualified specialist
workshop immediately.

In addition, the 00E5,00DFand0027 (USA) or 00E50025 and004D
(Canada) warning lamps light up in the instrument cluster and a
warning tone sounds.
ABS (Anti-lock Braking System) and ESP
®(Electronic Stability
Program) are malfunctioning. This means that Crosswind Assist
and hill start assist, for example, are also unavailable.
Further driving systems could be switched off automatically.
GWARNING
The brake system continues to function normally, but without the
functions listed above. The front and rear wheels could therefore
lock if you brake hard, for example.
The steerability and braking characteristics may be severely
affected. The braking distance in an emergency braking situation
can increase.
If ESP
®is not operational, ESP®is unable to stabilize the vehicle.
There is an increased risk of skidding and an accident.
XPull over and stop the vehicle safely as soon as possible, paying
attention to road and traffic conditions. Do not continue driv-
ing under any circumstances.

The distance warning function is temporarily inoperative. Pos-
sible causes are:
Rthe smart logo in the radiator trim is dirty.
Rfunction is impaired due to heavy rain or snow.
Rthe radar sensor system is temporarily inoperative, e.g. due to
electromagnetic radiation emitted by nearby TV or radio sta-
tions or other sources of electromagnetic radiation.
Rthe system is outside the operating temperature range.
Rthe on-board voltage is too low.
When the causes stated above no longer apply, the display message
disappears.
The distance warning function is operational again.
If the display message does not disappear:
XPull over and stop the vehicle safely as soon as possible, paying
attention to road and traffic conditions.

Stop Switch OffEngine
The coolant temperature has exceeded 230 ‡(110 †). The airflow to
the engine 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 an overheated engine can cause serious burns, which
can occur just by opening the engine compartment cover.
There is a risk of injury.
XPull over and stop the vehicle safely and switch off the engine,
paying attention to road and traffic conditions.
XSecure the vehicle against rolling away (Ypage 100).
XLeave the vehicle and keep a safe distance from the vehicle until
the engine has cooled down.
XCheck the coolant level and top up the coolant. Observe the notes
as you do so (Ypage 210).
XIf you need to add coolant more often than usual, have the engine coolant 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 230 ‡(110 †). Otherwise, the engine could be damaged.
Avoid subjecting the engine to heavy loads, e.g. driving in
mountainous terrain, and stop-and-go traffic.

GWARNING
If you drive with a flat tire, there is a risk of the following haz-
ards:
RA flat tire affects the ability to steer or brake the vehicle.
RYou could 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 as you do so.
XSecure the vehicle against rolling away (Ypage 100).
XCheck the tires and, if necessary, follow the instructions for a
flat tire (Ypage 161).
