Distance WarningInoperative
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.
XSecure the vehicle against rolling away (Ypage 100).
XClean the smart logo in the radiator trim (Ypage 158).
XRestart the engine.

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.

Low Fuel Level
The fuel level has dropped into the reserve range.
XRefuel at the nearest gas station.
00AC
Gas Cap Loose
The pressure in the fuel system has dropped. The fuel filler cap is
not closed correctly or the fuel system is leaking.
XCheck that the fuel filler cap is correctly closed.
If the fuel filler cap is not correctly closed:
XClose the fuel filler cap.
If the fuel filler cap is correctly closed:
XVisit a qualified specialist workshop.

When checking the oil level:
Rpark the vehicle on a level surface.
Rthe engine should be switched off for
approximately 5 minutes if the engine is at
normal operating temperature
Rif the engine is not at normal operating
temperature, e.g. if the engine was only
started briefly, wait approximately
30 minutes before carrying out the meas-
urement
Checking the oil level using the oil dip-
stick
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.
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
The engine compartment contains moving
components. Certain components, such as
the radiator fan, may continue to run or
start again suddenly when the ignition is
off. There is a risk of injury.
If you need to do any work inside the engine compartment:
Rswitch off the ignition
Rnever reach into the area where there is a
risk of danger from moving components,
such as the fan rotation area
Rremove jewelry and watches
Rkeep items of clothing and hair, for
example, away from moving parts
XOpen the engine compartment cover
(Ypage 149).
Example
XPull oil dipstick 0043out of the dipstick
guide tube.
XWipe off oil dipstick 0043.
XSlowly slide oil dipstick 0043into the guide
tube to the stop, and take it out again.
If the level is between MIN mark 0087and MAX
mark 0044, the oil level is correct.
Adding engine oil
GWARNING

GWARNING
If engine oil comes into contact with hot
components in the engine compartment, it
may ignite. There is a risk of fire and
injury.
Make sure that engine oil is not spilled
next to the filler neck. Let the engine cool down and thoroughly clean the engine oil
off the components before starting the
engine.
