168 Controls in detailAutomatic transmission*

Press program mode selector
switch1 repeatedly until the letter of
the desired program mode appears in
the multifunction display.
SelectCfor comfort driving:

The vehicle starts out in second
gear (both forward and reverse) for
gentler starts. This does not apply if
full throttle is applied or gear
range1 is selected.


Traction and driving stability are
improved on icy roads.


Upshifts occur earlier even when
you give more gas. The engine then
operates at lower rpms and the
wheels are less likely to spin.
One-touch gearshifting
Even with an automatic transmission, you
can change the gears manually and limit or
extend the gear range for automatic
shifting with the gear selector lever in
positionD.
!Never change the program mode when
the gear selector lever is out of
positionP. This could result in a
change of driving characteristics for
which you may not be prepared.iThe last selected program
mode (CorS) is switched on when the
engine is restarted.
!Allow engine to warm up under low
load use. Do not place full load on the
engine until the operating temperature
has been reached.
Shift into reverse gearR or parking
positionP only when the vehicle is
stopped.
Avoid spinning of a drive wheel for an
extended period when driving off on
slippery road surfaces. This may cause
serious damage to the drivetrain which
is not covered by the Mercedes-Benz
Limited Warranty.

Downshifting
Briefly press the gear selector lever to
the left in theD-direction.
The transmission will shift from the current
gear to the next lower gear as permitted by
the shift program. This action simulta-
neously limits the gear range of the
transmission (
page 166).Upshifting

Briefly press the gear selector lever to
the right in theD+direction.
The transmission will shift from the current
gear to the next higher gear as permitted
by the shift program. This action simul-
taneously extends the gear range of the
transmission.
Canceling gear range limit

Press and hold the gear selector lever
in theD+direction until
D reappears in
the multifunction display.
The transmission will shift from the current
gear range directly to gear rangeD.
Shifting into optimal gear range

Press and hold the gear selector lever
in theD-direction.
The transmission will automatically select
the gear range suited for optimal
acceleration and deceleration. This may
involve shifting down one or more gears.Emergency operation (Limp Home
Mode)
If vehicle acceleration worsens or the
transmission no longer shifts, the trans-
mission is most likely operating in limp
home (emergency operation) mode. In this
mode only second gear and reverse gear
can be activated.
Stop the vehicle in a safe location.

Move gear selector lever toP.

Turn off the engine.

Wait at least 10 seconds before
restarting.

Restart the engine.

Move gear selector lever to positionD
(for second gear) orR.

Have the transmission checked at an
authorized Mercedes-Benz Center as
soon as possible.
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced
vehicle control. Your vehicle’s ABS will not
prevent this type of loss of control.iTo avoid overrevving the engine when
the gear selector lever is moved to
theD-direction, the transmission will
not shift to a lower gear if the engine’s
max. speed would be exceeded.

Good visibility
Auto-dimming rear view mirrors*
The reflection brightness of the exterior
rear view mirror on the driver’s side and
the interior rear view mirror will respond
automatically to glare when

the ignition is switched on
and


incoming light from headlamps falls on
the sensor in the interior rear view
mirror.
The rear view mirror will not react if


reverse gearR is engaged


the interior lighting is turned on
Warning!
G
The auto-dimming function does not react if
incoming light is not aimed directly at
sensors in the interior rear view mirror.
The interior rear view mirror and the exterior
rear view mirror on the driver’s side do not
react, for example, if the rear window
sunshade* is in raised position.
Glare can endanger you and others.Warning!
G
In case of an accident, liquid electrolyte may
escape from the mirror housing if the mirror
glass breaks.
Electrolyte has an irritating effect. Do not
allow the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.
!Electrolyte drops coming into contact
with the vehicle paint finish can be
completely removed only while in the
liquid state and by applying plenty of
water.Warning!
G
Exercise care when using the passen-
ger-side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your
interior rear view mirror or glance over your
shoulder before changing lanes.

282 OperationIn the “Operation” section you will find
detailed information on operating, main-
taining and caring for your vehicle.The first 1 000 miles (1 500 km)
The more cautiously you treat your vehicle
during the break-in period, the more satis-
fied you will be with its performance later
on.

Drive your vehicle during the first
1 000 miles (1 500 km) at varying but
moderate vehicle and engine speeds.


During this period, avoid heavy loads
(full throttle driving) and excessive
engine speeds (no more than
2/3 of
maximum rpm in each gear).


Shift gears in a timely manner.


Avoid accelerating by kick-down.


Do not attempt to slow the vehicle
down by shifting to a lower gear using
the gear selector lever.


Select positions3,2 or1 only when
driving at moderate speeds (for hill
driving).


SelectC as the preferred shift program
(page 167) for the first 1 000 miles
(1 500 km). After 1 000 miles (1 500 km) you may
gradually increase vehicle and engine
speeds to the permissible maximum.
All of the above instructions, as may apply
to your vehicle type, also apply when
driving the first 1 000 miles (1 500 km)
after the engine or the rear differential has
been replaced.
iAlways obey applicable speed limits.
