Parking Brake
Press the button on your shift lever so that it's either in
the NORMAL or the POWER position. When it's in the
NORMAL position, the line on the button will be
showing. When in POWER, the line is not showing.
In the NORMAL position, the transaxle shifts at lower
engine speeds. For increased performance, you may
choose the POWER mode.
Setting the parking brake: Hold the regular brake
pedal down with your right foot. Push down the parking
brake pedal with your left foot. If the ignition is on, the
parking brake indicator light will come on.
