266 STARTING AND OPERATING
The parking brake lever is located in the center console.
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 center button, then lower the lever
completely.
Parking Brake
When the parking brake is applied with the ignition
switch in the ON position, the "Brake Warning Light" in
the instrument cluster will illuminate.
NOTE:
• When the parking brake is applied vehicle speed is
detected, the light will flash and a chime will sound to
alert the driver. Fully release the parking brake before
attempting to move the vehicle.
• This light only shows that the parking brake is ap-
plied. It does not show the degree of brake application.
When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away
from the curb on an uphill grade. For vehicles equipped
with an automatic transmission, apply the parking brake
before placing the shift lever in PARK, otherwise the load
on the transmission locking mechanism may make it
difficult to move the shift lever out of PARK. The parking
brake should always be applied whenever the driver is
not in the vehicle.
