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.SelectS for standard driving
(CL 63 AMG and CL 65 AMG: sporty
driving):


The vehicle starts out in first gear.


Upshifts occur later.
Steering wheel gearshift control
With drive positionD selected and driving
in program modeC orS, you can limit or

Do not place full load on the engine until the op-
erating 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
surfaces. This may cause serious damage to the

Automatic transmission
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 selected.
Stop the vehicle in a safe location.

Shift to park positionP.

Turn off the engine.

Wait at least 10 seconds before
restarting.

Restart the engine.

Shift to drive positionD (for second
gear) or reverse gearR.

Have the transmission checked at an
authorized Mercedes-Benz Center as
soon as possible.

492 Controls in detailAutomatic climate controlThe automatic climate control is operation-
al whenever the engine is running. You can
operate the climate control system in ei-
ther the automatic or manual mode. The
system cools or heats the interior depend-
ing on the selected interior temperature
and the current outside temperature.
It can only function optimally when you are
driving with the windows and the tilt/slid-
ing sunroof closed.
It is possible to completely deactivate the
climate control system (
page 493). Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.
i
If you have the air distribution and air vol-
ume automatically controlled, you can adjust the
temperature, footwell temperature and air flow.
The following basic settings are recommended:


Automatic air distribution control
(page 491)


Temperature: 72°F (22°C) (
page 494)


Footwell temperature: 0 (
page 274)


Air flow: focused (
page 275)
Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pages
and in the “COMAND automatic climate
control” section (
page 269). Otherwise
the windows could fog up, impairing visibili-
ty and endangering you and others.
Warning!
G
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval. A
clogged filter will reduce the air volume to
the interior and the windows could fog up,
impairing visibility and endangering you and
others. Have a clogged filter replaced as
soon as possible at an authorized
Mercedes-Benz Center.i
If the vehicle interior is hot, ventilate the in-
terior before driving off, see “Summer opening
feature” (
page 404). The automatic climate
control will then adjust the interior temperature
to the set value much faster.
Keep the air intake grille in front of the wind-
shield free of snow, leaves, sticks, and any other
debris.

524 Controls in detailUseful featuresAll information relevant to the emergency,
such as the location of the vehicle (deter-
mined by the GPS satellite location sys-
tem), vehicle model, identification number
and color are generated.
A voice connection between the Response
Center and the occupants of the vehicle
will be established automatically soon af-
ter the emergency call has been initiated.
The Response Center will attempt to deter-
mine more precisely the nature of the acci-
dent provided they can speak to an
occupant of the vehicle.The Tele Aid system is available if


it has been activated and is operation-
al. Activation requires a subscription
for monitoring services, connection,
and cellular air time


the relevant monitoring service and
GPS coverage are available and pass
the information on to the Response
Center


there is sufficient voltage in the vehicle
batteries
i
During the emergency call message “Emer-
gency Call Activated” is displayed, operation
from COMAND is not possible. The automatic cli-
mate control can be still adjusted using the
switches on the climate control panel.
i
If no vehicle occupant responds, an ambu-
lance will be sent to the vehicle immediately.
i
Location of the vehicle on a map is only pos-
sible if the vehicle is able to receive signals from
the GPS satellite network and pass the informa-
tion on to the Response Center.Warning!
G
If the indicator lamp in the SOS button is
flashing continuously and there was no
voice connection to the Response Center
established, then the Tele Aid system could
not initiate an emergency call (e.g. the rele-
vant mobile phone network is not available).
The message:

“Call Failed” appears in the multifunc-
tion display for approximately
10 seconds


A pop-up window with the message:
“Call could not be connected! Please dial
911 directly using the mobile telephone
keypad.” appears in the COMAND dis-
play. Confirm the message pressing
n

Should this occur, assistance must be sum-
moned by other means.
i
During the emergency call the mobile phone
is switched off automatically and must be
switched back on to make a call.
i
The “911” emergency call system is a public
service. Using it without due cause is a criminal
offense.
