Notes on breaking-in a new vehicle

Important safety notes
The sensor system of some driving and driving
safety systems adjusts automatically while a
certain distance is being driven after the vehi-
cle has been delivered or after repairs. Full
system effectiveness is not reached until the
end of this teach-in procedure.
New and replaced brake pads and discs only
reach their optimum braking effect after sev-
eral hundred kilometers of driving. Compen-
sate 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.
You should therefore drive at varying vehicle
R
and engine speeds for the first 1000 miles
(1500 km).
Avoid heavy loads, e.g. driving at full throt-
R
tle, during this period.
Change gear in good time, before the tach-
R
ometer needle is Ô of the way to the red
area of the tachometer.
Do not manually shift to a lower gear to
R
brake the vehicle.
Try to avoid depressing the accelerator
R
pedal beyond the point of resistance (kick-
down).
Ideally, for the first 1000 miles (1500 km),
R
drive in program E.
Additional breaking-in notes for Mercedes-
AMG vehicles:
Do not drive faster than 85 mph (140 km/h)
R
for the first 1,000 miles (1,500 km).
Only allow the engine to reach a maximum
R
engine speed of 4,500 rpm briefly.
Change gear in good time.
R
After 1,000 miles (1,500 km), you can
increase the engine speed gradually and bring
the vehicle to full speed.
You should also observe these notes on break-
ing-in if the engine or parts of the drive train
on your vehicle have been replaced.
Always observe the maximum permissible
speed.

Important safety notes
G
WARNING
Objects in the driver's footwell can restrict
the pedal travel or obstruct a depressed
pedal. The operating and road safety of the
vehicle is jeopardized. There is a risk of an
accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not
use loose floormats and do not place floor-
mats on top of one another.
G
WARNING
Unsuitable footwear can hinder correct
usage of the pedals, e.g.:
shoes with thick soles
R
shoes with high heels
R
slippers
R
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals.
G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could
affect, for example, the power steering and
the brake boosting effect. You will require
considerably more effort to steer and brake.
There is a risk of an accident.
Do not switch off the ignition while driving.
G
WARNING
If the parking brake has not been fully
released when driving, the parking brake
can:
overheat and cause a fire
R
lose its hold function.
