If you switch off the engine using
the key or the Start/Stop button,
the automatic transmission shifts

forward gears are available.
Changing gear
The automatic transmission shifts to the indi-
vidualg ears automaticallyw hen it is in trans-
mission position D.Gearshifting is deter-
mined by:

Accelerator peda lposition Your style of driving influences how the auto-
matic transmission shift sgear:
R little throttle: early upshifts
R more throttle: late upshifts AMG vehicles When shifting down, the double-clutc
hfunc-
tion is active regardless of the currently selec-
ted drive program. The double-clutc hfunction
reduces load change reactions and is condu-
cive to asport ydriving style. The sound gen-
erated by the double-clutc hfunction depends
on th edrivep rogram selected.

Introduction i
OnAMG vehicles andvehicles with
steering wheel gearshift paddles,y ou
can restrict or derestric tthe shift range
using the steerin gwheel gearshift paddles.
When the automatic transmission is in posi-
tion D,itisp ossible to restrict or derestrict
the shift range (Y page 153).
The shift range selected is shown in the mul-
tifunction display .The automatic transmis-
sion shifts only as far as the selected gear. Shift range: =
To use the engine's braking effect
5
To use the braking effect of the
engine on downhill gradients and
for driving:
R
on steep mountain roads
R in mountainous terrain
R in arduousc onditions 4
To use the braking effect of the
engine on extremely steep downhill
gradients and on long downhill
stretches
Restricting the shift range
X
Pull the left-hand steering wheel gearshift
paddle.
The automatic transmission shifts down
one gear and restrictst he shift range to the
relevant gear.
i If the engine exceeds the maximum
engine speed when shifting down, the auto-
matic transmission protectsa gainst engine
damage by not shifting down.
i If the maximum engine speed for the shift
range is reached and you continue to accel-
erate, the automatic transmission shifts up,
even if the shift range is restricted. This
prevents the engine from overrevving.
Extending the shift range X
Pull the right-hand steering wheel gearshift
paddle.
The shift range is derestricted. Automatic transmission

from overrevving. You must make sure that
the engine speed does not reach the red
area of the rev counter. Otherwise, there is
ar isk of engine damage.

shop immediately. The acceleration ability
is deteriorating.
The transmission no
longer changes gear. The transmission is in emergency mode.
It is only possible to shift into
secondgear and reverse gear.
X Stop.
X Shift the transmission to position P.
X Switch off the engine.
X Wait at least ten seconds before restarting the engine.
X Shift the transmission to position Dor R.
If D is selected, the transmission shifts into secondgear; ifRis
selected, the transmission shifts into reverse gear.

Important safety notes
G
WARNING
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Switch off the engine and the auxiliary heating
before refuelling. G
WARNING
Avoid contact with fuels.
It is hazardous to your health if your skin
comes into direct contact with fuels or you
breathe in fuel vapours. G
WARNING
Do not use petrol to refuel adiesel tank.N ever
mix diesel with petrol. Doin gsocould damage
the fuel system and the engine. The vehicle
could also catc hfire.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel vehicles with
apetrol engine. Even small
amounts of the wrong fuel result in damage
to the fuel system and the engine.
! Do not switch on the ignition if you acci-
dentally refuel with the wrong fuel. Other-
wise, the fuel will enter the fuel lines. Notify
aq ualified specialist workshop and have
the fuel tank and fuel lines drained com-
pletely.
! Overfilling the fuel tank could damage the
fuel system.
! Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
! Use afilter when adding fuel from afuel
can. The fuel lines and/or the diesel injec-
tion system could otherwise be blocked by
particles from the fuel can.

Important safety notes
G
WARNING
If flammable materials such as leaves, grass
or twigs are exposed to prolonged contact to
parts of the exhaust system that heat up, they
could ignite. There is arisk of fire.
Park the vehicle so that no flammable mate-
rials come into contact with parts of the vehi-
cle which are hot. Take particular care not to
park on dry grassland or harvested grain
fields. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect.Y ou will require considerably
more effort to steer and brake. There is arisk
of an accident.
Do not switch off the ignition while driving. G
WARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
R releasing the parking brake
R shifting the automatic transmission out of
the parking position P
R starting the engine.
They could also operate the vehicle's equip-
ment.T here isarisk of an accident and injury.
When leaving the vehicle, always take the key
with you and lock the vehicle. Never leave
children unsupervised in the vehicle.
! Am oving vehicle can lead to damage to
the vehicle or damage to the drive train.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the parking brake must be applied.
R the transmission must be in position Pand
the key must be removed from the ignition
lock.
R on uphill or downhill gradients, the front
wheels must be turned towards the kerb. Parking
