ProblemPossible causes/consequences and
Solutions
The engine is not
running smoothly and
is misfiring.
There is a malfunction in the engine electronics or in a mechanical
component of the engine management system.
XOnly depress the accelerator pedal slightly.
XHave the cause rectified immediately at a qualified specialist
workshop.
Otherwise, non-combusted fuel may get into the catalytic
converter and damage it.
The coolant
temperature display is
showing more than
248 ‡ (120 †). The
coolant warning lamp
may also be lit 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.
XStop as soon as possible and allow the engine and the coolant
to cool down.
XCheck the coolant level (Ypage 283). Observe the warning
notes as you do so and add coolant if necessary.

Important safety notes
GWARNING
If the engine speed is above the idling speed
and you engage transmission positionDor
R, the vehicle could pull away suddenly. There
is a risk of an accident.
When engaging transmission positionDorR,
always firmly depress the brake pedal and do
not simultaneously accelerate.
GWARNING
The automatic transmission switches to
neutral positionNwhen you switch off the
engine. The vehicle may roll away.There is a
risk of an accident.
After switching off the engine, always switch
to parking positionP. Prevent the parked
vehicle from rolling away by applying the
parking brake.

GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.

RStart the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
RMake sure that the ignition is switched on.
RWhen the vehicle is stationary, depress the

Kickdown
AMG vehicles:kickdown is only possible in
temporary manual drive programM. For
further information on manual drive program
M(Ypage 148).
Use kickdown for maximum acceleration:
XDepress the accelerator pedal beyond the
pressure point.
The automatic transmission shifts to a
lower gear depending on the engine speed.
XEase off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up.
Rocking the vehicle free
Shifting the transmission repeatedly between
gearsDandRmay help to free the vehicle if
it has become stuck in slush or snow. The
vehicle's engine management system limits
the speed to a maximum of 5 mph (9 km/h)
when shifting back and forth. To shift back
and forth between transmission positionsD
andR, move the selector lever up and down
beyond the pressure point.

Manual drive program
Introduction
In manual drive programM, you can change
gear yourself by using the steering wheel
paddle shifters. For this, the transmission
must be in positionD. The gear currently
selected and engaged is shown in the
multifunction display.
Manual drive programMdiffers from drive
programsE(drive programCon AMG
vehicles) andSwith regard to spontaneity,
responsiveness and smoothness of gear
changes.
GearDriving situations

\nYou can use the braking effect of
the engine on downhill gradients

drive programMwill be deactivated
automatically after a limited time, if the
driving situation permits. The automatic
transmission switches to the previously
activated drive programE(drive program

Upshifting
XPull the right-hand steering wheel paddle
shifter (Ypage 147).
The automatic transmission shifts up to the
next gear.
iAll vehicles (except AMG vehicles):in
order to preventengine damage the
automatic transmission automatically
shifts up:
Rif the maximumengine speed on the
currently engaged gear is reached and
Ryou continue to accelerate.
AMGvehicles:
!In manual drive programM, the automatic
transmission does not shiftup
automatically evenwhen the engine
limiting speed for the current gear is
reached. When the engine limiting speed is
reached, the fuel supply is cut to prevent
the engine from overrevving. Always make
sure that the engine speed does not reach
the red area of the tachometer. There is
otherwise a risk of engine damage.

Downshifting
XPull the left-hand steering wheel paddle
shifter (Ypage 147).
The automatic transmission shifts down to
the next gear.
iIf you slow down or stop without shifting
down, the automatic transmission
automatically shifts down.
iFor maximum acceleration, pull the left-
hand steering wheel paddle shifter until the
transmission selects the optimum gear for
the current speed.
iIf the engine exceeds the maximum
engine speed when shifting down, the
automatic transmission protects against
engine damage by not shifting down.
Kickdown
AMG vehicles:kickdown is only possible in
temporary manual drive programM.
You can also use kickdown for maximum
acceleration in manual drive programM.
XDepress the accelerator pedal beyond the
pressure point.
The automatic transmission shifts to a
lower gear depending on the engine speed.
XShift back up once the desired speed is
reached.
iDuring kickdown, you cannot change gear
using the steering wheel paddle shifters.
iIf you apply full throttle, the automatic
transmission shifts up to the next gear

!Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
!Use a filter when refueling from a fuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can.
Do not get into the vehicle againduring the
refueling process. Otherwise, electrostatic
