Automatic transmission
GWARNING
It is dangerous to shift the automatic
transmission out of parking position P or
neutral position N if the engine speed is
higher than idle speed. If your foot is not firmly
on the brake pedal, the vehicle could
accelerate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and when
your right foot is firmly on the brake pedal.
i It is only possible to shift the transmission
from position P to the desired position if
you depress the brake pedal. Only then is
the selector lever lock released.
XDepress the brake pedal and keep it

Release Park. Brake message appears
in the multifunction display, the parking
brake is still applied. Release the parking
brake.
i The vehicle locks centrally once you have
pulled away. The locking knobs in the doors
drop down.
You can open the doors from the inside at
any time.
You can also deactivate the automatic
locking feature ( Y page 210).
i Upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Hill start assist
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient.
It holds the vehicle for a short time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal
and depress it before the vehicle begins to
roll.
GWARNING
Never leave the vehicle when it is held by hill
start assist. After approximately one second,
hill start assist will no longer brake your
vehicle and it could roll away.
XTake your foot off the brake pedal.
i Once you have taken your foot off the
brake pedal, the vehicle is held for around
one second.

Shift ranges
Introduction
When the automatic transmission is in
position D, it is possible to restrict or
derestrict the shift range ( Y page 153).
The shift range selected is shown in the
multifunction display. The automatic
transmission shifts only as far as the selected
gear.
Shift range=You can use the engine's braking
effect.5To use the braking effect of the
engine on downhill gradients and
for driving:
R on steep mountain roads
R in mountainous terrain
R in arduous conditions4To use the braking effect of the
engine on extremely steep downhill
gradients and on long downhill
stretches
Restricting the shift range
XPress the selector lever to the left towards
D– .
or
XPull the left-hand steering wheel paddle
shifter.
The automatic transmission shifts down
one gear and restricts the shift range to the
relevant gear.
i If the engine exceeds the maximum
engine speed when shifting down, the
automatic transmission protects against
engine damage by not shifting down.
i If the maximum engine speed for the shift
range is reached and you continue to
accelerate, the automatic transmission
shifts up in order to prevent the engine
from overrevving, even if the shift range is
restricted.
Derestricting the shift rangeXBriefly press the selector lever to the right
towards D+.
or
XPull the right-hand steering wheel paddle
shifter.
The shift range is derestricted.
Clearing the shift range restriction
XPress and hold the selector lever towards
D+ until D is shown once more in the
multifunction display.
or
XPull and hold the right-hand steering wheel
paddle shifter until D is shown again in the
multifunction display.
The automatic transmission shifts from the
current shift range directly to D.
Selecting the ideal shift range
XPress the selector lever to the left towards
D– and hold it in position.
or
XPull the left-hand steering wheel paddle
shifter and hold it in position.
The automatic transmission shifts to the
gear which allows optimum acceleration
and deceleration. To do this, the automatic
transmission shifts down one or more
gears.Automatic transmission153Driving and parkingZ
Manual drive program
Switching on the manual drive program
The manual drive program is only available for
vehicles with the dynamic handling package.
Manual drive program M is different from
drive program S with regard to spontaneity,
responsiveness and smoothness of gear
changes.
Manual drive program M can be selected
using the program selector button. You can
change gears using the steering wheel paddle
shifters or the selector lever in manual drive
program M if the transmission is in position
D . The gear selected is shown in the
multifunction display.
XPress the program selector button
( Y page 151) repeatedly until M appears in
the multifunction display.
Upshifting
i Vehicles with the dynamic handling
package : if the maximum engine speed for
the shift range is reached and you continue
to accelerate, the automatic transmission
shifts up, except when manual drive
program M is selected.
XBriefly press the selector lever to the right
towards D+.
or
XPull the right-hand steering wheel paddle
shifter ( Y page 152).
The automatic transmission shifts up to the
next gear.
Downshifting
XBriefly press the selector lever to the left
towards D–.
or
XPull the left-hand steering wheel paddle
shifter ( Y page 152).
The automatic transmission shifts down to
the next gear.i If you brake the vehicle or stop without
shifting down, the automatic transmission
will shift down to a gear that will allow the
vehicle to accelerate or pull away again.
i To avoid overrevving the engine when
downshifting, the automatic transmission
does not shift to a lower gear if this would
result in the maximum engine speed being
exceeded.
Kickdown
You can also use kickdown for maximum
acceleration in manual drive program M.
XVehicles for USA: fully depress the
accelerator pedal.
The transmission shifts to a lower gear
depending on the engine speed.XVehicles for Canada: depress the
accelerator pedal beyond the pressure
point.
The transmission shifts to a lower gear
depending on the engine speed.
i During kickdown, you cannot change gear
using the steering wheel paddle shifters or
the selector lever.

Turn off the engine before refueling.
Whenever you are around gasoline, avoid
inhaling fumes and any skin or clothing
contact.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging to your
health.GWARNING
Overfilling of the fuel tank may create
pressure in the system which could cause a
gas discharge. This could cause the gasoline
to spray back out when removing the fuel
pump nozzle, which could cause personal
injury.
! Do not use diesel to refuel vehicles with a
gasoline engine. Even small amounts of the
wrong fuel result in damage to the fuel
system and engine.
! Do not switch on the ignition if you
accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel lines.
Notify a qualified specialist workshop and
have the fuel tank and fuel lines drained
completely.
Gasoline
Fuel grade
! You should only refuel with unleaded
premium-grade gasoline as this avoids
damaging the catalytic converter.
If engine running problems are apparent,
have the cause checked immediately and
repaired. Excess unburned fuel can
otherwise enter the catalytic converter,
leading to overheating and possibly
causing a fire.
! Use a filter when refueling from a fuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can.
i Only refuel with premium-grade unleaded
gasoline with a specified minimum octane
number of 91 (average value of 96 RON/
86 MON).
You will usually find information about the
fuel grade on the pump. If you cannot find
the label on the pump, ask the staff for
assistance.
You can find more information under "Fuel"
( Y page 342), or by contacting an
authorized Mercedes-Benz Service Center
or visiting http://www.mbusa.com (USA
only).

brake is engaged.
GWARNING
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it with
you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children could
release the parking brake and/or shift the
automatic transmission out of park position
P , either of which could result in an accident
and/or serious personal injury.
