The automatic transmission shifts into the
next lower gear.
i For maximum acceleration, pull and hold
the left gearshift control. Depending on the
engine speed the automatic transmission
selects the optimal gear for maximum
acceleration.
i When you brake or stop, the automatic
transmission shifts down into a gear from
which you can easily accelerate or take off.

Emergency operation (limp-home
mode)
If vehicle acceleration becomes less
responsive or sluggish or the automatic
transmission no longer shifts, the automatic
transmission is most likely operating in limp-
home (emergency operation) mode. In this
mode only second gear and reverse gear R
can be selected.

at an authorized Mercedes-Benz Center as
soon as possible.
Transfer case
This section applies to vehicles equipped with
all-wheel drive (4MATIC) only. Both the front
and rear axles are powered at all times when
the vehicle is being operated.
! Only conduct operational or performance
tests on a two-axle dynamometer. If such
tests are necessary, contact an authorized
Mercedes-Benz Center. You could
otherwise seriously damage the brake
system or the transfer case which is not
covered by the Mercedes-Benz Limited
Warranty.
! Because the ESP ®
operates
automatically, the engine and ignition must
be shut off (SmartKey in starter switch
position 0 or 1 or KEYLESS-GO start/stop
button in position 0 or 1) when the parking
brake is being tested on a brake test
dynamometer. Such testing should be no
longer than 10 seconds.
Active braking action through the ESP ®
may otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.

Should the vehicle’s system record any
conditions while driving, the number of
messages will reappear in the multifunction
display when the SmartKey in the starter
switch is turned to position 0 or removed
from the starter switch. With KEYLESS-GO,
the number of messages will reappear when
you turn off the engine by pressing the
KEYLESS-GO start/stop button and open the
driver’s door.
Except for high-priority messages, the vehicle
status message memory will be cleared when
you switch off the ignition.
Settings menu
Introduction
In the Settings menu there are two
functions: The function To reset, press
reset button for 3 seconds, with which
you can reset all the settings to the original
factory settings and a collection of submenus
with which you can make individual settings
for your vehicle.
The following settings and submenus are
available in the Settings menu:
RResetting to factory settings
(Y page 129)
RSubmenus in the Settings menu
(Y page 130)
RInstrument cluster submenu
(Y page 130)
RTime/Date submenu (Y page 132)
RLighting submenu (Y page 133)
RVehicle submenu (Y page 135)
RComfort submenu (Y page 135)
Resetting to factory settings
You can reset the settings of all submenus to
the factory settings.
For safety reasons, the function Lamp

The respective tire is indicated by a red
rectangle.
Restarting Advanced TPMSGWarning!
It is the driver’s responsibility to set the tire
inflation pressure to the recommended cold
tire inflation pressure. Underinflated tires
affect the ability to steer or brake the vehicle.
You might lose control over the vehicle.
When you restart the TPMS, the system sets
new reference values for each tire.
The TPMS must be restarted when you have
adjusted the tire inflation pressure to a new
level (e.g. because of different load or driving
conditions). The TPMS is then recalibrated to
the current tire inflation pressures.
Restart the TPMS after adjusting the tire
inflation pressure to the inflation pressure
recommended for the vehicle operating
condition. Tire pressure should only be
adjusted on cold tires. Observe the
recommended tire inflation pressure on the
Tire and Loading Information placard on the
driver’s door B-pillar. Some vehicles may have
supplemental tire pressure information for
driving at high speeds or for vehicle loads less
than the maximum loaded vehicle condition.
If such information is provided, it can be
found on the inside of the fuel filler flap.
XUsing the Tire and Loading Information
placard on the driver’s door B-pillar
( Y page 227) or the supplemental tire
inflation pressure information on the inside
of the fuel filler flap, make sure the tire
inflation pressure of all four tires is correct.XSwitch on the ignition.XPress button V or U on the
multifunction steering wheel repeatedly
until the standard display appears in the
multifunction display ( Y page 122).XPress button & or * repeatedly until
you see the current inflation pressures for
each tire appear in the display or the
following message appears in the
multifunction display: Tire pressure
displayed after
driving for
a few minutes.XPress the reset button ( Y page 117).
The following message will appear in the
multifunction display:

pressure monitor?XIf you wish to confirm: Press button
W .
The following message will appear in the
multifunction display:
Tire Pressure Monitor
Restarted
After driving a few minutes the system
verifies that the current tire inflation
pressures are within the system’s specified
range. Afterwards the current tire inflation
pressures are accepted as reference values
and then monitored.XIf you wish to cancel: Press button X.
i
When the wheel positions have been
changed, the inflation pressure of a tire
may be displayed for the wrong position
temporarily. After driving for a few minutes,
the inflation pressure will be shown for the
correct position.
Maximum tire inflation pressure
GWarning!
Never exceed the maximum tire inflation
pressure. Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adversely
affect handling and fuel economy, and are
more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort,
wear unevenly, increase stopping distance,
and result in sudden deflation (blowout)
because they are more likely to become
