Air conditioning
The air conditioning is operational while 
the engine is running and cools the interior 
air to the temperature set by the operator.Deactivating
It is possible to deactivate the air condi-
tioning (cooling) function of the climate 
control system. The air in the vehicle will 
then no longer be cooled or dehumidified.

Warning!
G
Any accumulation of snow and ice should be 
removed from the rear window before driv-
ing. Visibility could otherwise be impaired, 
endangering you and others.!If the rear window defroster switches 
off too soon and the indicator lamp 
starts blinking, this means that too 
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system 
responds automatically by deactivating 
the rear window defroster. 
As soon as the battery has sufficient 
voltage, the rear window defroster au-
tomatically turns itself back on.
iCondensation may drip out from under-
neath the vehicle. This is normal and 
not an indication of a malfunction.
Warning!
G
While driving, deactivate the air conditioning 
only temporarily to prevent window fogging.

Warning!
G
The speed stored in memory should only be 
set again if prevailing road conditions per-
mit. Possible acceleration or deceleration 
differences arising from returning to preset 
speed could cause an accident and/or seri-
ous injury to you and others.
iDepressing the accelerator pedal does 
not deactivate cruise control. After 
brief acceleration (e.g. for passing), 
cruise control will resume the last 
speed set.
iVehicles with automatic transmission: 
When you use the cruise control lever 
to decelerate, the transmission will au-
tomatically downshift if the engine’s 
braking power does not brake the vehi-
cle sufficiently.
Vehicles with manual transmission: 
The set cruise controlled speed is 
switched off when declutching exceeds 
4 seconds during downshifting a gear.

Telephone*
Radio transmitters, such as a portable tele-
phone or a citizens band unit, should only 
be used inside the vehicle if they are con-
nected to an antenna that is installed on 
the outside of the vehicle.
The external antenna must be approved by 
Mercedes-Benz. Please contact an autho-
rized Mercedes-Benz Center for informa-
tion on the installation of an approved 
external antenna. Refer to the radio trans-
mitter operation instructions regarding use 
of an external antenna.
Warning!
G
Never touch the heating element or sides of 
the cigarette lighter; they are extremely hot. 
Hold the knob only.
When leaving the vehicle, always remove the 
key from the steering lock, and lock your 
vehicle. Do not leave children unattended in 
the vehicle, or with access to an unlocked 
vehicle. Unsupervised use of vehicle equip-
ment may cause an accident and/or serious 
personal injury.iThe cigarette lighter socket can be 
used to accommodate electrical acces-
sories up to a maximum 85 W.
Warning!
G
Never operate radio transmitters equipped 
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna) 
from inside the vehicle while the engine is 
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or serious 
personal injury.

158 OperationThe first 1000 miles (1500 km)In the “Operation” section you will find de-
tailed information on operating, maintain-
ing and caring for your vehicle.
The first 1000 miles (1500 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 
1000 miles (1500 km) at varying but 
moderate vehicle and engine speeds.
During this period, avoid heavy loads 
(full throttle driving) and excessive en-
gine speeds (no more than 
2/3 of max-
imum rpm in each gear).
Do not attempt to slow the vehicle 
down by shifting to a lower gear using 
the selector lever or the gearshift lever.
Shift gears in a timely manner.
Avoid accelerating by kick-down.
Do not brake the vehicle by shifting to 
a lower gear using the selector lever.
Select positions3,2 or1 only when 
driving at moderate speeds (for hill 
driving). After 1000 miles (1500 km) you may grad-
ually increase vehicle and engine speeds 
to the permissible maximum.
!Additional instructions for AMG vehi-
cles:
During the first 1000 miles 
(1500 km), do not exceed a speed 
of 85 mph (140 km/h).
During this period, avoid engine 
speeds above 4500 rpm in each 
gear.
All of the above, as may apply to your 
vehicle type, also apply when driving 
the first 1000 miles (1500 km) after the 
engine or the rear differential has been 
replaced.
iAlways obey applicable speed limits.
