Important safety notes
G
WARNING
New brake pads/linings only have optimal
braking performance after several hundred
kilometres .Until then, compensate for this by
applying greate rforce to the brake pedal. This
also applies when brake pads/linings or
brake discs have been changed. The first 1,500 km
The more you look after the engine when it is
new, the more satisfied you will be with its
performance in the future.
R Therefore, drive at varying speeds and
engine speeds for the first 1,500 km.
R Avoid heavy loads on the engine during this
period, e.g. driving at full throttle.
R Change gear in good time, at the latest
when the rev counter needle is 2
/ 3 of the
way to the red area in the rev counter dis-
play.
R Do not manually shift to a lower gear to
brake the vehicle. Vehicles with automatic transmission:
R
If possible, do not depress the accelerator
pedal past the point of resistance (kick-
down).
R Only select shift ranges 3,2or 1when driv-
ing slowly, e.g. in mountainous terrain.
After 1,500 km, you may gradually bring the
vehicle up to full road and engine speeds.
Additional running-in notes for AMG vehicles:
R do not drive at speeds above 140 km/hf or
the first 1,500 km.
R only allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
i You should also observe these notes on
running in if the engine or parts of the drive
train on your vehicle have been replaced. AMG vehicles with rear axle locking
differential
Your vehicle is fitted with a self-locking dif-
ferential on the rear axle. Change the oil after
a running-in period of 3,000 km to improve
protection of the rear axle differential. This oil
change extends the service life of the differ-
ential. Have the oil change carried out at a
qualified specialist workshop. Mercedes-
Benz recommends that you use a Mercedes-
Benz Service Centre for this purpose. Driving

WARNING
Do not place any objects in the driver's foot-
well. If you use a floormat or carpet in the
driver's footwell, make sure that it is correctly
secured and that there is sufficient clearance
for the pedals.
Do not place several floormats on top of one
another.
Loose objects or the floormats could other-
wise get caught between the pedals if you 136

accelerate or brake suddenly. You will then
no tb e able to brake, declutch or accelerate
as intended. This could lead to accidents and
injury. G
WARNING
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. This could cause you
to lose control of your vehicle and cause an
accident.
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only set the automatic transmission to the
respective drive positions when the vehicle
is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. Otherwise, you could damage the
drive train.
! AMG vehicles: at low engine oil tempera-
tures (below +20 †), the maximum engine
speed is restricted in order to protec tthe
engine. To protect the engine and maintain
smooth engine operation, avoid driving at
full throttle when the engine is cold. Key positions
