AMG vehicles)
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 danger
of skidding and having an accident. Make sure
that no persons or obstacles are in the area
around the vehicle.
Start-off assist enables optimum acceleration
from a standstill. For this, a suitably high-grip
road surface is required, along with the tyres
and vehicle being in good condition.
Do not activate start-off assist on public
roads.
