Gear lever
! Only engage gear when the clutch pedal is
depressed.
! When shifting to
5thand 6thgear, you
must press the shift lever to the right. Oth-
erwise, you could shift unintentionally into
3rd or4th gear and damage the engine or
transmission.
If you shift down at too high a speed (trans-
mission braking), this can cause the engine to overrev, leading to engine damage.
Do not use the clutch bite point to keep the
vehicle stationary on uphill gradients.
There is otherwise a risk of damaging the
clutch.
! On long and steep downhill gradients,
especially if the vehicle is laden or towing a
trailer, you must shift into gear 1, 2or3in
good time. This uses the engine's braking
effect. This relieves the load on the brake
system and prevents the brakes from over- heating and wearing too quickly. k

The automatic transmission
changes gear automatically. All
forward gears are available.
Driving tips
Changing gear The automatic transmission shifts to the indi-
vidual gears automatically when it is in trans-
mission position D. Gearshifting is deter-
mined by:
R the selected drive program
R the position of the accelerator pedal
R the road speed
Accelerator pedal position Your style of driving influences how the auto-
matic transmission shifts gear:
R little throttle: early upshifts
R more throttle: late upshifts Holding the vehicle stationary on uphill
gradients G
WARNING
If the clutch overheats, the electronic man-
agement system is automatically deactivated. This interrupts the power transmission. The
vehicle may, for example, roll backwards on
gradients. There is a risk of an accident.
Never hold the vehicle stationary on uphill
gradients by depressing the accelerator.
The clutch may overheat if you hold the vehi- cle stationary on uphill gradients by depress- ing the accelerator pedal. If the clutch over-
heats, a warning tone sounds.

Shifting gears !
Mercedes-AMG vehicles:
the automatic
transmission does not shift up automati-
cally even when the engine limiting 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 rev counter. There is otherwise a risk of engine damage. X
To shift up: pull steering wheel gearshift
paddle ;.
The automatic transmission shifts up to the next gear.
All vehicles (except Mercedes-AMG
vehicles): if the maximum engine speed on
the currently engaged gear is reached and
you continue to accelerate, the automatic
transmission automatically shifts up in
order to prevent engine damage.
X To shift down: pull steering wheel gear-
shift paddle :.
The automatic transmission shifts down to
the next gear.
Automatic downshifting occurs when
coasting.
If the engine exceeds the maximum engine speed when shifting down, the automatic
transmission protects against engine dam-
age by not shifting down. Gearshift recommendation
The gearshift recommendations assist you in
adopting an economical driving style. The rec- ommended gear is shown in the multifunction
display.
X Shift to recommended gear ;according
to gearshift recommendation :when

Upshifting (Mercedes-AMG vehicles) !
The automatic transmission does not shift
up automatically even when the engine lim-
iting 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 rev counter. There is otherwisea risk of engine damage. Before the engine speed reaches the red area,
an upshift indicator will be shown in the mul-
tifunction display.
