Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.

specialist workshops: (Y page 27).Notes on breaking-in a new vehicle
Important safety notes
The sensors of certain drive and driving safety
systems automatically reset during driving for
a certain distance after the vehicle has been
delivered or after repairs have been carried
out. Complete system effectiveness is
reached only after completion of this teach-
in procedure.
New and replaced brake pads and discs only
reach their optimum braking effect after
several hundred kilometers of driving.
Compensate for this by applying greater force
to the brake pedal. The first 1000 miles(1500 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 You should therefore drive at varying
vehicle and engine speeds for the first
1000 miles (1500 km).
R Avoid heavy loads, e.g. driving at full
throttle, during this period.
R When shifting gears manually, upshift in
good time, before the tachometer needle
reaches 00C3of the way to the red area of the
tachometer. R
Do not manually shift to a lower gear to
brake the vehicle.
R Try to avoid depressing the accelerator
pedal beyond the point of resistance
(kickdown).
R All vehicles (except AMG vehicles):
ideally, for the first 1,000 miles (1,500 km),
drive in program E.
After 1000 miles (1500 km), you can increase
the engine speed gradually and 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 1,000 miles
(1,500 km).
R Only allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
R Change gear in good time.
R Ideally, for the first 1,000 miles (1,500 km),
drive in program C.
You should also observe these notes on
breaking in if the engine or parts of the drive
train on your vehicle have been replaced.
Always observe the respective speed limits. Driving

these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without sufficient ventilation.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with
the manufacturer's specifications. For this
reason, all work on the engine must be carried
out by qualified and authorized Mercedes-
Benz technicians.
The engine settings must not be changed
under any circumstances. Furthermore, all
specific service work must be carried out at
regular intervals and in accordance with the
Mercedes-Benz service requirements. Details
