MSolutions The engine does not
start. The starter motor
can be heard. R
There is a malfunction in the engine electronics.
R There is a malfunction in the fuel supply.
X Before attempting to start the engine again, turn the key in the
ignition back to position 0or press the Start/Stop button
repeatedly until all indicator lamps in the instrument cluster go
out.
X Try to start the engine again (Y page 161). Avoid excessively
long and frequent attempts to start the engine, as this will drain
the battery.
If the engine does not start after several attempts: X Consult a qualified specialist workshop. The engine does not
start. The starter motor
can be heard. The
reserve fuel warning
lamp is lit and the fuel
gauge display is at the
reserve level. The fuel tank is empty.
X Refuel the vehicle. The engine does not
start. You cannot hear
the starter motor. The on-board voltage is too low because the battery is too weak or
discharged.
X Jump-start the vehicle (Y page 364).
If the engine does not start despite attempts to jump-start it:
X Consult a qualified specialist workshop. The starter motor was exposed to a thermal load that was too high.
X Try to start the engine again.
If the engine still does not start:
X Consult a qualified specialist workshop. The engine is not run-
ning smoothly and is
misfiring. There is a malfunction in the engine electronics or in a mechanical
component of the engine management system.
X Only depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it.
X Have the cause rectified immediately at a qualified specialist
workshop. 166

MSolutions The coolant tempera-
ture display is showing
more than 120 †. A
display message may
also appear in the mul-
tifunction display and a
warning tone may
sound. The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X Stop as soon as possible and allow the engine and the coolant to
cool down.
X Check the coolant level (Y page 340). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct, the engine radiator fan may be faulty.
The coolant is too hot and the engine is no longer being cooled
sufficiently.
X If the coolant temperature is below 120 †, you can continue
driving to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving in
mountainous terrain and stop-start traffic. Automatic transmission

WARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate. G
WARNING
The automatic transmission switches to neu-
tral position Nwhen you switch off the engine.
The vehicle may roll away. There is a risk of an
accident.

Driving tips
Changing gear The automatic transmission shifts to the indi-
vidual gears automatically when it is in trans-
mission position D. Gearshifting is deter-
mined by:
R the selected drive program (Y page 171)
R the position of the accelerator pedal
(Y page 170)
R the road speed
Accelerator pedal position Your style of driving influences how the auto-
matic transmission shifts gear:
R little throttle: early upshifts
R more throttle: late upshifts 170

Automatic drive program E Drive program
E(drive program Con AMG
vehicles) is characterised by the following:
R comfort-oriented engine settings.
R optimal fuel consumption resulting from
the automatic transmission shifting up
sooner.
R the vehicle pulling away more gently in
forward and reverse gears unless the accel-
erator pedal is depressed fully.
R increased sensitivity. This improves driving
stability on slippery road surfaces, for
example.
R the automatic transmission shifting up
sooner. This results in the vehicle being driven at lower engine speeds and the
wheels being less likely to spin.
Automatic drive program S Drive program
Sis characterised by the fol-
lowing:
R sporty engine settings
R the vehicle pulls away in first gear
R the automatic transmission shifting up
later
R as a result of the later automatic transmis-
sion shift points, the fuel consumption pos- sibly being higher
Manual drive program M General notes
In this drive program, you can briefly change
gear yourself by using the steering wheel
gearshift paddles. The transmission must be
in position
D.
You can activate manual drive program Min
the E(C in AMG vehicles) and Sautomatic
drive programs.
AMG vehicles: as well as temporary drive
program M, you can also activate permanent
drive program M. Further information about
permanent drive program M(Y page 173).
Activating X Shift the transmission to position D.
X Pull the left or right steering wheel gearshift
paddle (Y page 172).

Shifting gears
If you pull on the left or right steering wheel
gearshift paddle, the automatic transmission
switches to manual drive program Mfor a
limited amount of time. Depending on which
gearshift paddle is pulled, the automatic 172
Automatic transmissionDriving and parking

transmission immediately shifts into the next
gear up or down, if permitted.
X To shift up: pull the right-hand steering
wheel gearshift paddle (Y page 172).
The automatic transmission shifts up to the next gear.
If the maximum engine speed on the cur-
rently engaged gear is reached and you
continue to accelerate, the automatic
transmission automatically shifts up in
order to prevent engine damage.
AMG vehicles: the automatic transmission
will not shift up to the next gear when the
engine speed is very low.
X To shift down: pull on the left-hand steer-
ing wheel gearshift paddle (Y page 172).
The automatic transmission shifts down to the next gear.
If the engine exceeds the maximum engine
speed when shifting down, the automatic
transmission protects against engine dam- age by not shifting down.
Automatic downshifting occurs when
coasting.
Gearshift recommendation The gearshift recommendations assist you in
adopting an economical driving style. The rec- ommended gear is shown in the multifunction
display.
X Shift to recommended gear ;according
to gearshift recommendation :when
shown in the multifunction display of the
instrument cluster. Deactivating
If you have activated manual drive program
M
, it will remain active for a certain amount of
time. Under certain conditions the minimum
amount of time is extended, e.g. in the case of lateral acceleration, during an overrun phase
or when driving on steep terrain.
When manual drive program Mis deactivated,
the automatic transmission shifts into the
automatic drive program that was last selec-
ted.
You can also deactivate manual drive pro-
gram Myourself:
X Pull on the right-hand steering wheel gear-
shift paddle and hold it in place
(Y page 172).
or
X Use the DIRECT SELECT lever to shift the
transmission position.
