Breaking-in notes
To preserve the engine during the first
1000 miles (1500 km):
R
Drive at varying road speeds and engine
speeds.
R
Do not drive at speeds greater than 85 mph
(140 km/h).
R
Drive the vehicle in drive program A
or ; .
R
Shift to the next highest gear at the very lat‐
est when the needle reaches the last third
before the red area in the tachometer.
R
Do not shift down a gear manually in order to
brake.
R
Avoid overstraining the vehicle, e.g. driving at
full throttle.
R
Do not depress the accelerator pedal past
the pressure point (kickdown).
R
Only increase the engine speed gradually and
accelerate the vehicle to full speed after
1000 miles (1500 km).
This also applies when the engine or parts of the
drivetrain have been replaced.
Please also observe the following breaking-in
notes:
R
In certain driving and driving safety systems,
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.
R
Brakepads, brake discs and tires that are
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 optimized acceleration
If all necessary requirements and activation con‐
ditions are fulfilled, the best possible accelera‐
tion can be achieved from a standstill.
Do not use the optimized 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 174).
Pulling away with optimized acceleration
& WARNING Risk of skidding and having
an accident from wheels spinning
When you use optimized acceleration, indi‐
vidual wheels could spin and you could lose
control of the vehicle.
If ESP
® is deactivated, there is a risk of skid‐
ding and accident.
#

are in the close vicinity of your vehicle.
