Running-in notes
To preserve the engine during the first 1,500 km:
Drive at varying road speeds and engine
R
speeds.
Do not drive at speeds greater than
R
140 km/h.
Drive the vehicle in driving mode A
R
or ;.
Shift to the next highest gear at the very latest
R
when the needle reaches the last third before
the red area in the rev counter.
Do not shift down manually in order to brake.
R
Avoid overstraining the vehicle, e.g. driving at
R
full throttle.
Do not depress the accelerator pedal past the
R
pressure point (kickdown).
Only increase the engine speed gradually and
R
accelerate the vehicle to full speed after
1,500 km.
This also applies when the engine or parts of the
drivetrain have been replaced.
Please also observe the following running-in
notes:
In certain driving and driving safety systems,
R
the sensors adjust automatically while a cer-
tain distance is being driven after the vehicle
has been delivered or after repairs. Full sys-
tem effectiveness is not reached until the end
of this teach-in process.
Brake pads, brake discs and tyres that are
R
either new or have been replaced only achieve
Driving and parking 213
optimum braking effect and grip after several
hundred kilometres of driving. Compensate for
the reduced braking effect by applying greater
force to the brake pedal.
Notes on optimised acceleration
If all necessary requirements and activation con-
ditions are fulfilled, the best possible acceleration
can be achieved from a standstill.
Do not use the optimised acceleration on public
roads. Individual wheels could spin and you could
lose control of the vehicle. There is an increased
risk of skidding and/or accident.
Be sure to observe the safety notes and informa-
®
tion on ESP
(
page 266).

Pulling away with optimised acceleration
& WARNING Risk of skidding and having an
accident from wheels spinning
When you use optimised acceleration, individ-
ual wheels could spin and you could lose con-
trol of the vehicle.
