The red warning
lamp does not go
out approx-
imately 4 seconds
after the ignition
is switched on, or
it lights up again.The restraint systems have malfunctioned.
GWARNING
If the restraint systems are malfunctioning, individual systems could
be triggered inadvertently or might not be triggered at all in the event
of an accident.
There is an increased risk of injury and accidents.
XDrive on with care.
XVisit a qualified specialist workshop immediately.
# The red battery
indicator lamp is
lit while the
engine is running.The battery is not being charged. Possible causes are a defective
alternator or a torn poly-V-belt.
XStop the vehicle as soon as possible, paying attention to road and
traffic conditions.
XCheck the poly-V-belt.
XIf the poly-V-belt is torn: do not continue driving. Consult the near-
est qualified specialist workshop.
XIf the poly-V-belt is not damaged: have the vehicle checked as soon
as possible by a qualified specialist workshop.
#The red battery

lit while the
engine is running.The battery is faulty.
XStop the vehicle as soon as possible, paying attention to road and
traffic conditions.
XDo not continue driving under any circumstances.
XConsult a qualified specialist workshop.
#The yellow brake
pad wear indica-
tor lamp is lit after
the engine is star-
ted or while the
vehicle is in
motion.The brake pads/linings have reached their wear limit.
GWARNING
Braking performance can be impaired.
There is a risk of an accident.
XHave the brake pads/linings replaced as soon as possible at a
qualified specialist workshop.
4 The yellow engine
oil level warning
lamp is lit after
the engine is star-
ted or while the
vehicle is in
motion.The oil level has dropped to the minimum level.
XCheck the engine for oil loss.
XIf oil loss is detected: consult a qualified specialist workshop imme-
diately.
XIf no oil loss is detected: check the oil level and add engine oil
(Ypage 221).

XInsert oil dipstick:back into the guide tube
as far as it will go and remove it again.
If the level is between minimum mark =and
maximum mark ;, the oil level is correct.
XIf the oil level has dropped to or below mini-
mum mark=, open cap ?and add engine oil
(
Ypage 222).
The difference in quantity between marks ;
and =is approximately 2 qt (2 l).
XInsert the oil dipstick into the guide tube as far
as it will go.
XClose the hood (Ypage 219).
OM651 4-cylinder diesel engine:
At outside temperatures between 32 ‡ (–0 †)
and 86 ‡ (30 †), the oil level can be checked
when the engine is cold.
Measuring the engine oil when the engine is cold
is less precise than measuring when the engine
is at normal operating temperature.
When the appropriate warning is shown in the
display
XAdd engine oil (Ypage 222)
or
XHave engine oil siphoned off.
Adding engine oil
GWARNING
If engine oil comes into contact with hot com- ponents 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 com-
ponents before starting the engine.
!The alternator is located below the engine
oil filler neck. If engine oil spills onto the alter-
nator, there is a danger of alternator damage.
Be very careful when adding engine oil.
HEnvironmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful to
the environment.
!Do not add too much oil. adding too much
engine oil can result in damage to the engine
or to the catalytic converter. Have excess
engine oil siphoned off.
!Do not use any additives in the engine oil.
This could damage the engine.
XOpen the hood (Ypage 218).
XUnscrew and remove cap ?.
XAdd engine oil.
XReplace cap?on the filler neck and tighten.
When doing so, make sure that the cap
engages correctly.
XCheck the oil level with the oil dipstick
(Ypage 221) or on the display (Ypage 220).
XClose the hood.
Coolant
GWARNING
The engine cooling system is pressurized, par-
ticularly when the engine is warm. When
opening the cap, you could be scalded by hot
coolant spraying out. There is a risk of injury.
Let the engine cool down before opening the
cap. Wear eye and hand protection when
opening the cap. Open the cap slowly half a
turn to allow pressure to escape.
Only check the coolant level and/or fill the cool-
ant if the vehicle is on a level surface and the
engine has cooled down. The coolant tempera-
ture must be below 122 ‡ (50 †).
!Check the engine cooling and heating sys-
tem regularly for leaks.
If a large quantity of coolant is lost, have the
cause traced and rectified at a qualified spe-
cialist workshop.
GWARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.
!Take care not to spill any coolant on painted
surfaces. You could otherwise damage the
paintwork.
