Problem
Possible causes/consequences and P Solutions
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 278).
If the engine does not start despite attempt stoj ump-start it:X
Consult aq ualified specialist workshop.
The starter motor was exposed to at hermal load that was too high.X
Allow the starter motor to cool down for approximately two minutes. X
Try to start the engine again.
If the engine still does not start: X
Consult aq ualified specialist workshop.
The engine is not running
smoothly and is misfir-
ing. There is am alfunction in the engine electronics or in am echanical
componen toft he engine management system.X
Only depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it. X
Have the cause rectified immediately at aq ualified specialist work-
shop.
The coolant temperature
gauge shows av alue
above 248 ‡( 120 †).
The coolant warning
lamp may also be on and
aw arning 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 260). Observe the warning notes
as you do so and add coolant if necessary.

instead of transmission position [ .
If manual gearshifting is deactivated, the gears
will be selected automatically.
Temporar ys etting X
To activate: shift the DIRECT SELECT lever to
position [ . X
Pull steering wheel paddle shifter C or D .
Temporary setting will be active for ac ertain
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. X
To deactivate: pull steering wheel paddle
shifter D and hold it in place.

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 ®
,i mproves the trac-
tion of your vehicle whenever ad rive 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 ,f or vehicle
speed, for braking in good time and for staying in
your lane.
If ad rive wheel spins due to insufficient grip: R
Only depress the accelerator pedal as far as
necessary when pulling away. R
Accelerate less when driving.
i In 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.
DYNAMIC BODY CONTROL
General notes DYNAMI CB ODY CONTROL offers improved
driving comfort and continuously controls the
calibration of the dampers. The
damping characteristics adapt to the current
operating and driving situation.
The damping is tuned individually to each wheel
and depends on: R
your driving style, e.g. sporty R
the road surface conditions R
the drive program selected
The drive program can be set using the
DYNAMI CS ELECT button ( Y
page 128).
Selecting Comfort mode In the Comfort drive program, the driving char-
acteristic sofy our vehicle are more comforta-
ble. Therefore, select this drive program if you
prefer am ore comfortable driving style. Also
select the Comfort drive program when driving
fast on straight roads, e.g. on straight stretches
of highway. X
Press DYNAMI CS ELECT button ( Y
page 128)
as many times as necessary until the Com-
fort drive program is selected.160
