PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied.
The parking brake lever is located on the outboard side of
the drivers seat. To apply the parking brake, pull the
lever up as firmly as possible. To release the parking
brake, pull the lever up slightly, press the side button
with your thumb, then lower the lever completely.
When the parking brake is applied with the ignition
switch in the MAR (ACC/ON/RUN) position, the Brake
Warning Light in the instrument cluster will illuminate.
