174 Controls in detailAutomatic transmissionGear ranges
With the gear selector lever in drive
positionD and driving in shift programC
orS, you can select a gear range for the
automatic transmission to operate within.
Gear selector lever (
page 175):
You can limit the gear range by pressing
the gear selector lever to the left (D-), and
reverse the gear range limit by pressing
the gear selector lever to the right (D+).
Steering wheel gearshift paddles
(
page 177):
You can limit the gear range by pulling the
left gearshift paddle, and reverse the gear
range limit by pulling the right gearshift
paddle.The selected gear range appears in the
right multifunction display (
page 117).
i
If, when driving in shift programC and S the
maximum engine speed for the gear range has
been reached, the transmission shifts up auto-
matically, even if the gear range is restricted. In
shift program MAN the transmission will not
shift up automatically.
Effect
é
The transmission shifts through
fourth gear only.
è
The transmission shifts through
third gear only.With this selection you can use the
braking effect of the engine.
Effect
ç
The transmission shifts through
second gear only.
Allows the use of engine’s braking
power when driving:

on steep downgrades


in mountainous regions


under extreme operating
conditions
æ
The transmission operates in the
first gear only.
For maximum use of engine’s
braking effect on very steep or
lengthy downgrades.

226 Controls in detailUseful featuresProgramming tips
If you are having difficulty programming
the integrated remote control, here are
some helpful tips:

Check the frequency of the hand-held
remote control5 (typically located on
the reverse side of the remote). The in-
tegrated remote control is compatible
with radio-frequency devices operating
between 280-390 MHz.


Put a new battery in hand-held remote
control5. This will increase the likeli-
hood of the hand-held remote control
sending a faster and more accurate sig-
nal to the integrated remote control.


While performing step 3, hold
hand-held remote control5 at differ-
ent lengths and angles from the signal
transmitter button (2, 3 or4) you
are programming. Attempt varying
angles at the distance of 2 to 5 in
(5 to 12 cm) away or the same angle at
varying distances.


If another hand-held remote control is
available for the same device, try the
programming steps again using that
other hand-held remote control. Make
sure new batteries are in the hand-held
remote control before beginning the
procedure.


Straighten the antenna wire from the
garage door opener assembly. This
may help improve transmitting and/or
receiving signals.
i
Certain types of garage door openers are in-
compatible with the integrated remote control. If
you should experience further difficulties with
programming the integrated remote control,
contact an authorized Mercedes-Benz Center, or
call Mercedes-Benz Customer Assistance
Center (in the USA) at 1-800-FOR-MERCedes, or
Customer Service (in Canada) at
1-800-387-0100.

243 Operation
Driving instructions
Road salts and chemicals can adversely
affect braking efficiency. Increased pedal
force may become necessary to produce
the normal braking effect.
Depressing the brake pedal periodically
when traveling at length on salt-strewn
roads can bring road-salt-impaired braking
efficiency back to normal.
If the vehicle is parked after being driven
on salt-treated roads, the braking
efficiency should be tested as soon as
possible after driving is resumed.
For more information, see “Winter driving”
(
page 292).
Standing water
Warning!
G
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
Warning!
G
If the vehicle becomes stuck in snow, make
sure snow is kept clear of the exhaust pipe
and from around the vehicle with the engine
running. Otherwise deadly carbon monoxide
(CO) gases may enter vehicle interior
resulting in unconsciousness and death.
To assure sufficient fresh air ventilation,
open a window slightly on the side of the
vehicle not facing the wind.Warning!
G
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point do not guarantee that the
road surface is free of ice.
!
Do not drive through flooded areas or water
of unknown depth. Before driving through water,
determine its depth. Never accelerate before
driving into water. The bow wave could force
water into the engine and auxiliary equipment,
thus damaging them.
If you must drive through standing water, drive
slowly to prevent water from entering the pas-
senger compartment or the engine compart-
ment. Water in these areas could cause damage
to electrical components or wiring of the engine
or transmission, or could result in water being in-
gested by the engine through the air intake caus-
ing severe internal engine damage. Any such
damage is not covered by the Mercedes-Benz
Limited Warranty.
