Only increase the engine speed gradually and
R
accelerate the vehicle to full speed after
1,000 miles (1,500 km).
This also applies when the engine or parts of the
drivetrain have been replaced.
Please also observe the following breaking-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.
Brakepads, brake discs and tires that are
R
either new or have been replaced only ach‐
ieve optimum braking effect and grip after
several hundred kilometers of driving. Com‐
pensate for the reduced braking effect by
applying greater force to the brake pedal.
Notes on driving
& WARNING Risk of accident due to
objects in the driver's footwell
Objects in the driver's footwell may impede
pedal travel or block a depressed pedal.
This jeopardizes the operating and road
safety of the vehicle.
Stow all objects in the vehicle securely
#
so that they cannot get into the driver's
footwell.
Always install the floor mats securely
#
and as prescribed in order to ensure
that there is always sufficient room for
the pedals.
Do not use loose floor mats and do not
#
place floor mats on top of one another.
