Transmission positions
BPark position
Only shift the transmission into
positionPwhen the vehicle is sta-
tionary (
Ypage 189). The parking
lock should not be used as a brake
when parking. Always apply the
electronic parking brake in addi-
tion to the parking lock in order to
secure the vehicle.
If the vehicle electronics are mal-
functioning, the transmission may
be locked in position P. Have the
vehicle electronics checked imme-
diately at a qualified specialist
workshop.
Park position Pis automatically
engaged if:
Ryou switch off the engine using
the SmartKey and remove the
SmartKey
Ryou switch off the engine using
the SmartKey or using the Start/ Stop button and open the driv-
er's door or front-passenger
door
Rthe driver's door is opened when
the vehicle is stationary or driv-
ing at very low speed and the
transmission is in position Dor R
CReverse gear
Only shift the transmission into
position Rwhen the vehicle is sta-
tionary.
ANeutral
Do not shift the transmission to N
while driving. Otherwise, the auto-
matic transmission could be dam-
aged.
No power is transmitted from the
engine to the drive wheels.
Releasing the brakes will allow you
to move the vehicle freely, e.g. to
push it or tow it.
If ESP
®is deactivated or faulty:
shift the transmission to position N
if the vehicle is in danger of skid-
ding, e.g. on icy roads.
If you switch the engine off with the
transmission in position Ror D, the
automatic transmission shifts to N
automatically.
!Rolling in neutral Ncan damage
the drive train.
7Drive
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. This automatic gear shift-
ing behavior is determined by:
Rthe selected drive program (Ypage 177)
Rthe position of the accelerator pedal
(
Ypage 176)
Rthe road speed
Accelerator pedal position
Your style of driving influences how the auto-
matic transmission shifts gear:
Rlittle throttle: early upshifts
Rmore throttle: late upshifts

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 deacti-
vated, the automatic transmission shifts into
the automatic drive program that was last
selected.
You can also deactivate manual drive pro-

Upshifting (Mercedes-AMG vehicles)
!In manual drive program M, 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 tachometer. There is otherwise a risk of
engine damage.

Transfer case
!
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.
!Because ESP®is an automatic system,
the engine and ignition must be switched
off (SmartKey in position 0or 1or Start/
Stop button in position 0or 1) when the
electric parking brake is being tested on a
brake dynamometer (maximum
10 seconds).
Braking triggered automatically by ESP
®
may seriously damage the brake system.
!Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised,
as doing so will damage the transmission.
This section is only valid for vehicles with 4-
wheel drive (4MATIC). Power is always trans-
mitted to both axles.
Refueling
Important safety notes
GWARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, open flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before refueling.
GWARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that fuel does not come into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.

Parking
Important safety notes
GWARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system or exhaust
gas flow. There is a risk 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.
GWARNING
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. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking position P.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
!Always secure the vehicle correctly
against rolling away. Otherwise, the vehicle
or its drivetrain could be damaged.
To ensure that the vehicle is secured against
rolling away unintentionally:
Rthe electric parking brake must be applied.
Rthe transmission must be in position Pand
the SmartKey must be removed from the
ignition lock.
Rthe front wheels must be turned towards
the curb on steep uphill or downhill gradi-
ents.
Rthe empty vehicle must be secured at the
front axle with a wheel chock or similar, for
example, on uphill or downhill gradients.
Ra laden vehicle must also be secured at the
rear axle with a wheel chock or similar, for
example, on uphill or downhill gradients.

The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or there is a malfunction
in the system, it may not be possible to apply
the released parking brake.
XIf this is the case, only park the vehicle on
level ground and secure it to prevent it roll-
ing away.
XShift the automatic transmission to posi-
tionP.
It may not be possible to release an applied
parking brake if the on-board voltage is low or
there is a malfunction in the system. Contact
a qualified specialist workshop.
iThe electric parking brake performs a
function test at regular intervals while the
engine is switched off. The sounds that can
be heard while this is occurring are normal.
Applying or releasing manually
XTo engage: push handle :.
