WARNING
Objects in the driver's footwell can restrict the
pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle
is jeopardised. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Fit the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use
loose floormats.
i Bear in mind that power transmission
between the engine and the transmission
is interrupted when the engine is switched
off. For this reason, shift the automatic
transmission to P when the engine is
switched off and the vehicle is stationary.
Apply the parking brake to prevent the vehi-
cle from rolling away.
