WARNING
Driving when your engine is overheated can
cause some fluids which may have leaked into
the engine compartment to catch fire. You
could be seriously burned.
Steam from an overheated engine can cause
serious burns which can occur jus tby opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of the
vehicle and do no tstand nea rthe vehicle until
the engine has cooled down.
The coolant temperature gauge is in the
instrumentc luster on the right-hand side.
Under normal operating conditions and with
the specified coolan tlevel, the coolant
temperature may rise to 248 ‡ (120 †).
! Adisplay message is shown if the coolant
temperature is too high.
If the coolant temperature is over
248 ‡(120 †), do not continue driving. The
engine will otherwise be damaged. Tachometer
The red band in the tachometer indicates the
engine's overrevving range.
! Do not drive in the overrevving range, as
this could damage the engine.
The fuel supply is interrupted to protect the
engine when the red band is reached. Outside temperature display
The outside temperature display is in the
multifunction display (Y page 183).G
WARNING
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose. Indicated temperatures just above the
freezing point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
Changes in the outside temperature are
displayed after a shor tdelay. Speedometer with segments
The segments in the speedometer indicate
which speed range is available.
Cruise control (Y page 156) activated:
The segments light up from the stored speed
to the maximum speed.
DISTRONIC PLUS (Y page 158) activated:
One or two segments in the set speed range
light up.
DISTRONIC PLUS detects a vehicle in front:
The segments between the speed of the
vehicle in fron tand the stored speed light up. Operating the on-board computer

Problems when programming
If you are experiencing problems
programming the integrated garage door
opener on the rear-view mirror, take note of
the following instructions:
R Check the transmitter frequency of garage
door drive remote control 0020.This can
usually be found on the back of the remote
control.
The integrated garage door opener is
compatible with devices that have units
which operate in the frequency range of
280 to 390MHz.
R Replace the batteries in garage door
remote control 0020.This increases the
likelihood that garage door remote control
0020 will transmit a stronga nd precise signal
to the integrated garage door opene rinthe
rear-view mirror.
R When programming, hold remote control
0020 at varying distances and angles from the
button that you are programming. Try
various angles at a distance between
2a nd 12 inches (5 to 30 cm) or at the same
angle bu tatvarying distances.
R If another remote control for the same
garage door drive is available, repeat the
same programming steps with this remote
control. Before performing these steps,
make sure that new batteries have been
installed in garage door driv eremote
control 0020.
R Note that some remote controls only
transmit for a limited amount of time (the
indicator lamp on the remote control goes
out). Press button 0021on remote control
0020 again before transmission ends.
R Align the antenna cable of the garage door
opener unit. This can improve signal
reception/transmission.

when the hood is open and the engine is
running.
The radiator fan may continue to run for
approximately 30seconds or may even restart
after the engine has been switched off. For
this reason, you must not reach into the fan
rotation area. G
WARNING
The engine is equipped with a transistorized
ignition system. Because of the high voltage,
it is dangerous to touch any components
(ignition coils, spark plug sockets, diagnostic
socket) of the ignition system:
R with the engine running
R while starting the engine
R when the ignition is switched on and the
engine is turned manually
X Make sure that the windshield wipers are
switched off. G
WARNING

Make sure that the windshield wipers are
switched off. Remove the SmartKey or make
sure that no ignition position has been
selected with KEYLESS-GO. All indicator
lamps must be off in the instrument panel. X

Engine compartmentMaintenance and care

Adding engine oil
G
WARNING
If engine oil comes into contact with hot
engine parts, it may ignite and you could burn
yourself .Do not spill any engine oil on hot
engine parts. H
Environmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful
to the environment.
! Only use engine oils and oil filters that
have been approved for vehicles with a
service system. You can obtain a list of the
engine oils and oil filters tested and
approved in accordance with the
Mercedes-Benz Specifications for Service
Products at any Mercedes-Benz Service
center.
Damage to the engine or exhaust system is
caused by the following:
R using engine oils and oil filters that have
not been specifically approved for the
service system
R replacing engine oil and oil filters after
the interval for replacement specified by
the service system has been exceeded
R using engine oil additives.
! 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. Example: engine oil cap
X
Turn cap 0002counterclockwise and remove
it.
X Add engine oil.
If the oil level is at or below the MIN mark
on the oil dipstick, add 0.55 US qt to
1.1 US qt (0.5 to 1.0 l)of engine oil.
X Replace cap 0002on the filler neck and turn
clockwise.
Ensure that the cap locks into place
securely.
X Check the oil level again with the oil
dipstick (Y page 261).
Further information on engine oil
(Y page 326). Checking and adding other service
products
Checking the coolant level G
WARNING
In order to avoid any potentially serious burns:
R use extreme caution when opening the
hood if there are any signs of steam or
coolant leaking from the cooling system, or
if the coolant temperature display indicates
that the coolant is overheated.
R do not remove the pressure cap on the
coolant reservoir if the coolant temperature
is above 158 ‡(70 †). Allow the engine to
cool dow nbefore removing the cap. The
coolant reservoir contains hot fluid and is
under pressure. 262
