A
Neutral
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:
only shift the transmission to posi-
tion N if the vehicle is in danger of
skidding, e.g. on icy roads.
When you switch off the engine, the
automatic transmission automati-
cally shifts into neutral N.7
Drive
The automatic transmission
changes gear automatically. All
forward gears are available.
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 ( Y page 155)
R the position of the accelerator pedal
R the road speed Driving tips
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.
All vehicles (except AMG vehicles): the
Stop vehicle Shift to P Leave engine
running display message appears in the mul-
tifunction display. You will only be able to
continue your journey once the clutch has
cooled down and the display message in the
multifunction display has disappeared.
AMG vehicles: the Trans. oil overhea‐
ted Drive on with care display message
appears in the multifunction display.
Do not hold the vehicle stationary on uphill
gradients by depressing the accelerator
pedal. Instead, only ever hold the vehicle sta-
tionary on uphill gradients by:
R depressing the brake pedal
R activating the HOLD function
R engaging the electric parking brake
Kickdown AMG vehicles:
it
is only possible to use kick-
down in temporary manual drive program M.
For further information on the manual drive
program M, see ( Y page 156).
Use kickdown for maximum acceleration:
X Depress the accelerator pedal beyond the
pressure point.
The transmission shifts to a lower gear
depending on the engine speed.
X Ease off the accelerator pedal once the
desired speed is reached.
The

automatic transmission shifts back up.154

Problems with the transmission
Problem Possible causes/consequences and
M SolutionsThe transmission has
problems shifting gear. The transmission is losing oil.
X
Have the transmission checked at a qualified specialist work-
shop immediately. The acceleration ability
is deteriorating.
The transmission no
longer shifts into all of
the gears.
Reverse gear can no
longer be engaged. The transmission is in emergency mode.
X
Stop.
X Shift the transmission to position P.
X Switch off the engine.
X Wait at least 10seconds before restarting the engine.
X Shift the transmission to position D.
X Have the transmission checked at a qualified specialist work-
shop immediately. Refuelling
Important safety notes
G
WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, naked flames, creating
sparks and smoking. Switch off the engine
and,
if applicable, the auxiliary heating before
refuelling. G
WARNING
Fuels are poisonous and hazardous to health.
There is a danger of injury.
Do

not swallow fuel or let it come into contact
with skin, eyes or clothing. Do not inhale fuel
vapours. Keep fuels out of the reach of chil-
dren.
If you or others come into contact with fuel,
observe the following:
R Wash the fuel off any affected areas of skin
with water and soap immediately.
R If you get fuel in your eyes, rinse them thor-
oughly with clean water immediately. Seek
immediate medical attention. R
If fuel is swallowed, seek immediate medi-
cal attention. Do not induce vomiting.
R Change any clothing that has come into
contact with fuel immediately. G
WARNING
Electrostatic charge can cause sparks and
thereby ignite fuel vapours. There is a risk of
fire and explosion.
Always

touch the vehicle body before opening
the fuel filler flap or touching the fuel pump
nozzle. This discharges any electrostatic
charge that may have built up. G
WARNING
Vehicles with a diesel engine:
If you mix diesel fuel with petrol, the flash
point

of this fuel mixture is lower than that of
pure diesel fuel. When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is a risk of fire.
Never refuel with petrol. Never add petrol to
diesel fuel.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with a petrol engine. Do not switch Refuelling
