gearbox, in sequential mode,
-
position A
on an electronic gearbox or position D
on an automatic gearbox.

on triggering of the ESP system for safety reasons. It is possible to exceed the programmed speed
temporarily by pressing the accelerator pedal.

pads
Brake wear depends on the style
of driving, par ticularly in the case
of vehicles used in town, over shor t
distances. It ma
y be necessary to have the condition of the brakes checked, even between vehicle services. Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake pads are worn. The
gearbox does not require any
maintenance (no oil change).
Refer to the servicing booklet for the
details of the level checking interval for this component.
