Important safety notes
G
WARNING
If you use start-off assist, individual wheels
may start to spin and the vehicle may skid. If
ESP
®
is deactivated, there is a greater dan-
ger of skidding and having an accident.
Make sure that no persons or obstacles are
in the vicinity of the vehicle.
Start-off assist enables optimum acceleration
from a standstill. For this, a suitably high-grip
road surface is required and the vehicle and
tires must be in good working order.
Do not activate start-off assist on public roads.
Observe the safety notes on driving safety sys-
tems (Y page 60).
Be sure to read the safety notes and informa-
tion on ESP
®
