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 miles of driving. Compen‐
sate for the reduced braking effect by apply‐
ing 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
®
(
