the starter motor.The on-board voltage is too low because the battery is too weak or
discharged.
XJump-start the vehicle (Ypage 295).
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.
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.

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 level is too low. The coolant is too hot and the engine is no

automatic transmission shifting up sooner.
Rthe vehicle pulls away more gently in forward
and reverse gears, unless the accelerator
pedal is depressed fully.
Rthe vehicle has improved driving stability, for
example on slippery road surfaces.
Rthe 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 characterized by the follow-
ing:
Rsporty engine settings.
Rthe vehicle pulls away in first gear.
Rthe automatic transmission shifts up later.

All vehicles (except Mercedes-AMG vehi-
cles:)Mand the selected gear appear in the
multifunction display.
Shifting gears
If you pull on the left or right steering wheel
paddle shifter, the automatic transmission
switches to manual drive programMfor a limi-
ted amount of time. Depending on which steer- ing wheel paddle shifter is pulled, the automatic
transmission immediately shifts into the next
gear down or up, if permitted.
XTo shift up: pull the right-hand steering wheel
paddle shifter (Ypage 132).
The automatic transmission shifts up to the
next gear.
If the maximum engine speed on the currently
engaged gear is reached and you continue to accelerate, the automatic transmission auto-
matically shifts up in order to prevent engine
damage.
Mercedes-AMG vehicles: the automatic
transmission will not shift up to the next gear
when the engine speed is very low.
XTo shift down: pull on the left-hand steering
wheel paddle shifter (Ypage 132).
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 damage
by not shifting down.
Automatic down shifting occurs when coast-
ing.
Shift recommendation
The gearshift recommendations assist you in
adopting an economical driving style. The mul-
tifunction display shows the recommended
gear.
XShift to recommended gear 0044according to
gearshift recommendation 0043when 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.
If manual drive program Mhas been deactiva-
ted, the automatic transmission shifts into the
automatic drive program that was last selected.
You can also deactivate manual drive program
M yourself:
XPull on the right-hand steering wheel paddle
shifter and hold it in place (Ypage 132).
