Problems with the engine
ProblemPossible causes/consequences andMSolutions
The engine does not
start. The starter motor
can be heard.RThere is a malfunction in the engine electronics.
RThere is a malfunction in the fuel supply.
Before attempting to start the engine again:
XTurn the SmartKey back to position 0in the ignition lock.
or
XPress the Start/Stop button repeatedly until all indicator lamps in
the instrument cluster go out.
XTry to start the engine again (Ypage 164). Avoid excessively long
and frequent attempts to start the engine as these will drain the
battery.
If the engine does not start after several attempts:
XConsult a qualified specialist workshop.
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 376).
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.
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 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 356). Observe the warning notes
as you do so and add coolant if necessary.

Rthe vehicle pulling away more gently in
forward and reverse gears, unless the accel-
erator pedal is depressed fully.

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.

Shifting gears
If you pull on the left or right steering wheel
paddle shifter, the automatic transmission
switches to manual drive program Mfor a limi-
ted amount of time. Depending on which 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 174).
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 174).
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 rec-
ommended gear is shown in the multifunction
display.
XShift to recommended gear ;according to

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 174).

Upshifting
!In manual drive program M, the automatic
transmission does not shift up automatically
even when the engine limiting speed for the
current gear is reached. When the engine lim-
iting 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.

Transfer case
This section is only valid for vehicles with 4-
wheel drive (4MATIC). Power is always trans-
mitted to both axles.
!Performance tests may only be carried out
on a 2-axle dynamometer. The brake system
or transfer case could otherwise be damaged. Contact a qualified specialist workshop for a
performance test.
!Since ESP®engages automatically, the igni-
tion must be switched off (the SmartKey or
Start/Stop button must be in position 0or 1)
if:
Rthe electric parking brake is being tested
on a brake dynamometer
Rthe vehicle is being towed with only one
axle raised (not permitted for vehicles with
4MATIC).
The brake system could otherwise be dam-
aged.
!Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised, as doing so will damage the transmission.

cable for other purposes. It may otherwise be damaged.
The vehicle is supplied with a country-specific
charging cable for connection to a mains socket.
Only use the charging cable supplied with the
vehicle or a charging cable approved for the

iIf you use the supplied 12 A charging cable
to charge a high-voltage battery:
Rthe charge time increases considerably
Relectrical consumption increases consider-
ably
Where possible, charge the high-voltage bat-

then can certified electrical energy consump-
tion levels be reached.
iThe charging process can vary depending on
the power supply. Therefore, always observe
