Driving and parking 255
The rear wing improves the rear axle output and,
therefore, the vehicle's driving stability. You can
move the rear wing into an inclined and a flat
position.
When you move the rear wing into the inclined
position, the rear axle output and the air resist-
ance increase.
Unscrew the bolts 1 with a socket wrench.
#
Tilt the rear wing as far as it will go, upwards
#
into an inclined position, or downwards into a
flat position.
Equip the bolts 1 with a releasable, medium-
#
strength bolt lock and tighten them.
Specified tightening torque: 10 Nm.
