lamps, interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window
defroster can be activated again. Activating/deactivating air-
recirculation mode
Points to observe before use You can deactivate the flow of fresh air if
unpleasant odors are enteringt he vehicle
from outside. The air already inside the
vehicle will then be recirculated.
If you switch on air-recirculation mode, the
windows can fog up more quickly, in
particular at low temperatures. Only use air-
recirculation mode briefly to prevent the
windows from fogging up.
The operation of air-recirculation mode is the
same for all control panels.

red area of the tachometer.
R Do not manually shift to alower gear to
brake the vehicle.
R If possible, do not depress the accelerator
pedal past the point of resistance
(kickdown).
R Only select shift ranges 3,2or 1when
driving slowly, e.g. in mountainous terrain. After 1000 miles (1500 km), you can increase
the engine speed graduall
yand accelerate
the vehicle to full speed.
Additional breaking-in notes for AMG
vehicles:
R Do not drive faster than 85 mph
(140 km/h) for the first 1000 miles
(1500 km).
R Only allow the engine to reach amaximum
engine speed of 4500 rpm briefly.
R Change gear in good time.
i You should also observe these notes on
breaking in if the engine or parts of the drive
train on your vehicle have been replaced.
i Always observe the respective speed
limits. AMG vehicles with self-locking rear
axle differential
Your vehicle is equipped with aself-locking
differential on the rear axle. To protec tthe
differential on the rear axle, carry out an oil
change after abreaking-in phase of
2000m iles (3000 km). This oil change
prolongs the servic elife of the differential.
Have the oil change carried out at aqualified
specialist workshop. Driving
