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.
i Read the information on qualified
specialist workshops: (Y page 24).Notes on breaking-in a new vehicle
Important safety notes
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
1,000 miles (1,500 km).
R Avoid heavy loads, e.g. driving at full
throttle, during this period.
R Change gear in good time, before the
tachometer needle is 00C3of the way to the
red area of the tachometer.
R Do not manually shift to a lower gear to
brake the vehicle.
Vehicles with automatic transmission:
R Ideally, for the first 1,000 miles (1,500 km),
drive in program C.
R If possible, do not depress the accelerator
pedal past the point of resistance
(kickdown). After 1,000 miles (1,500 km), you can
increase the engine speed gradually and bring
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.
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 a self-locking
differential on the rear axle. To protect the
differential on the rear axle, carry out an oil
change after a breaking-in phase of
2,000 miles (3,000 km). This oil change
prolongs the service life of the differential.
Have the oil change carried out at a qualified
specialist workshop. Mercedes-Benz
recommends that you use an authorized
Mercedes-Benz Center for this purpose. Driving
