ProblemPossible causes/consequences andMSolutions
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.
XJump-start the vehicle (Ypage 273).
If the engine does not start despite attempts to jump-start it:
XConsult a qualified specialist workshop.
The starter motor was exposed to a thermal load that was too high.
XAllow the starter motor to cool down for approximately two minutes.
XTry to start the engine again.
If the engine still does not start:
XConsult a qualified specialist workshop.
The engine is not running
smoothly and is misfir-
ing.There is a malfunction in the engine electronics or in a mechanical
component of the engine management system.
XOnly depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it.
XHave the cause rectified immediately at a qualified specialist work-
shop.
The coolant temperature
gauge shows a value
above 248 ‡ (120 †).
The coolant warning
lamp may also be on 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 257). Observe the warning notes
as you do so and add coolant if necessary.

Manual gear shifting
General notes
You can change gear yourself using the steering wheel paddle shifters. The transmission must be
in position D.
Depending on which steering wheel paddle
shifter is pulled, the automatic transmission
immediately shifts into the next gear down or
up, if permitted. Mercedes-AMG vehicles:
to use manual shift-
ing, you have two options:
Rtemporary setting
Rpermanent setting
If you activate manual gearshifting, the multi-
function display will show the current gear
instead of transmission position D.
If manual gearshifting is deactivated, the gears
will be selected automatically.
Temporary setting
XTo activate: shift the DIRECT SELECT lever to
position D.
XPull steering wheel paddle shifter :or;.
Temporary setting will be 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.
XTo deactivate: pull steering wheel paddle
shifter ;and hold it in place.
or
XUse the DIRECT SELECT lever to switch the
transmission position.

AMG adaptive sport suspension sys-
tem
General notes
The electronically controlled damping system
works continuously. This improves driving
safety and ride comfort.
The damping is tuned individually to each wheel
and depends on:
Ryour driving style, e.g. sporty
Rthe road surface condition, e.g. bumps
Ryour individual selection of "Sport" or "Com-
fort"
The suspension setting is adjusted using the
corresponding button in the center console.
iThe mode can also be set using the AMG
DYNAMIC SELECT controller (Ypage 128).
Each time you start the engine with the Smart-
Key or the Start/Stop button, Comfort mode is
activated. For further information about starting
the engine, see (
Ypage 122).
Sport mode
158Driving system s

The firmer setting of the suspension tuning in
Sport mode ensures even better contact with
the road. Select this mode when employing a
sporty driving style, e.g. on winding country
roads.
XPress button:.
Indicator lamp ;lights up. You have selected
Sport mode.
The AMG Suspension System SPORT

sage appears in the multifunction display.

In Comfort mode, the driving characteristics of
your vehicle are more comfortable. Select this

style, but also when driving fast on straight
roads, e.g. highways.

4MATIC
!
Never tow the vehicle with one axle raised.
This may damage the differential. Damage of
this sort is not covered by the Mercedes-Benz
Limited Warranty. All wheels must remain
either on the ground or be fully raised.
Observe the instructions for towing the vehi-
cle with all wheels in full contact with the
ground.
4MATIC, together with ESP
®, improves the trac-
tion of your vehicle whenever a drive wheel
spins due to insufficient grip.
If you fail to adapt your driving style, 4MATIC can neither reduce the risk of accident nor override
the laws of physics. 4MATIC cannot take
account of road, weather and traffic conditions.
4MATIC is only an aid. You are responsible for
the distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
your lane.
If a drive wheel spins due to insufficient grip:
ROnly depress the accelerator pedal as far as
necessary when pulling away.
RAccelerate less when driving.
iIn wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if you
use winter tires (M+S tires), with snow chains
if necessary.
Suspension with Adaptive Damping
System
General notes
A suspension with the Adaptive Damping Sys-
tem provides improved driving comfort and con-
tinuously controls the calibration of the damp-
ers. The damping characteristics adapt to the
current operating and driving situation.
The damping is tuned individually to each wheel
and depends on:
Ryour driving style, e.g. sporty
Rthe road surface conditions
Rthe drive program selected
The drive program can be set using the
DYNAMIC SELECT button (
Ypage 127).
Selecting Comfort mode
In the Comfort drive program, the driving char-
acteristics of your vehicle are more comforta-
ble. Therefore, select this drive program if you
prefer a more comfortable driving style. Also
select the Comfortdrive program when driving
fast on straight roads, e.g. on straight stretches of highway.
XPress DYNAMIC SELECT button (Ypage 127)
as many times as necessary until the Com-
fort drive program is selected.

theSport drive program ensures even better
contact with the road. Select this drive program
when employing a sporty driving style, e.g. on
