WARNING
If you use RACE START, individual tires may
start to spin and the vehicle could skid.
Depending on the selected ESP
there is an increased risk of skidding and
having an accident. Make sure that no per-
sons, animals or obstacles are within range
of the vehicle.
RACE START enables optimal acceleration
from a standing start. For this, a suitably high-
grip road surface is required and the vehicle
and tires must be in good working order.
