Rthe course of the road is suitable ,e.g. there
are no steep up or downhill gradients.
Ryou are no longer depressing the accelerator

!Mercedes-AMG vehicles: the automatic
transmission does not shift up automatically

current gear is reached. When the engine lim-
iting spee disreached, the fuel supply is cut to
prevent the engine fromo verrevving. Always
make sure thatt he engine speeddoesn ot

continue to accelerate, the automatic trans-
mission automaticall yshifts up in order to
prevent engine damage.

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

Upshifting (Mercedes-AMG vehicles)
!The automatic transmission does not shift
up automatically even when the engine limit-
ing 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 arisk of
engine damage.
Before the engine speed reaches the red area,
an upshift indicator will be shown in the multi-
function display.
XWhen message :appears in the multifunc-
tion display,p ull on the right-hands teering

Kickdown
XFor maximum acceleration, depress the
accelerator pedal beyond the pressure point. The automatic transmission shifts to alower
gear depending on the engine speed.
XShift back up once the desired speed is
reached. During kickdown, you cannot shift gears using
the steering wheel paddle shifters.
If you apply full throttle, the automatic trans-
mission shifts up to the next gear when the
maximum engine speed is reached. This pre-
ventst
he engine from overrevving.
Mercedes-AMG vehicles: kickdown is only
possible in the temporary setting.

Transfer case
This section is only valid for vehicles with 4-
wheel drive (4MATIC). Power is always trans-
mitted to both axles.
!Performancet ests may only be carried out
on a2 -axle dynamometer. The brake system
or transfer case could otherwise be damaged. Contact aqualified specialist workshop for a
performancet est.
!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 abrake 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.
