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.Gear selector lever one-touch
gearshifting
With the gear selector lever in drive posi-
tion D and driving in shift programC orS,
you can limit or extend the gear range.
With the MAN shift program activated, you
can use the gear selector lever to manually
shift the gears.
The following instructions describe opera-
tion of the gear selector lever when driving
in the shift programC orS.
!Never change the program when the gear
selector lever is out of park positionP. This could
result in a change of driving characteristics for
which you may not be prepared.
iFor information on using the gear selector
lever in shift program MAN, see “Manual shift
program” (
page 179).
!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 park positionP only
when the vehicle is stopped.
Avoid spinning of a drive wheel for an extended
period when driving off on slippery road

Emergency operation
(Limp-Home Mode)
If vehicle acceleration becomes less re-
sponsive or sluggish or the transmission
no longer shifts, the transmission 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 to park
positionP.
Turn off the engine.
Wait at least 10 seconds before
restarting.

Automatic climate control
Deactivating
It is possible to deactivate the cooling
function of the automatic climate control
system. The air in the vehicle will then no
longer be cooled or dehumidified.
Press ± button (page 188).
The indicator lamp on the ±
button comes on. The cooling function
switches off after a short delay.Activating
Moist air can fog up the windows. You can
dehumidify the air with the air
conditioning.
Press ± button again (page 188).
The indicator lamp on the ± button
goes out.
The air conditioning uses the refrigerant
R134A. This refrigerant is free of CFCs
which are harmful to the ozone layer.
Residual heat and ventilation
With the engine switched off, it is possible
to continue to heat or ventilate the interior
for up to 30 minutes. This feature makes
use of the residual heat produced by the
engine.
iUnder certain circumstances, e.g. when the
fuel system is too hot and needs to be cooled,
the cooling switches on again automatically. The
red lamp on the ± button the automatic
climate control panel flashes.
After cooling the fuel system sufficiently, the air
conditioning switches off again and the red lamp
stops flashing.
!If you press the ± button on the auto-
matic climate control panel and it starts to flash,
this indicates that the air conditioning is losing
refrigerant. The compressor has turned off. The
air conditioning cannot be turned on again.
Have the air conditioning checked at the nearest
authorized Mercedes-Benz Center.
iHow long the system will provide heating
depends on the coolant temperature and the
selected temperature. The blower will run at low
speed regardless of the air distribution control
setting.
