Driving and Driving Safety

f Press the stalk forward to position 2 until you
feel it click into place.
The memory is cleared and the green readi-
ness light goes out.
The memory is cleared if the ignition is switched
off when the vehicle is parked.

engine-speed range, you therefore have to
change down to a lower gear.
