NOTICE:
Driving with the parking brake on can overheat
the parts in the system. You may have to replace
them, and you could also damage other parts of
your vehicle.
Electric/Hydraulic Parking Brake
(If Equipped)
CAUTION:
It will take a few seconds for the parking brake
to fully apply, and even longer when it is cold
outside. Do not leave your vehicle until the
parking brake applies fully. Without the parking
brake applied, your vehicle is free to move. It
could hit someone or something.
To apply the parking brake, pull the knob toward you.
Then shift the transmission to NEUTRAL (N)
or PARK (P).
Push the knob in to release the parking brake. The
ignition must be in ON and the shift lever out of
PARK (P) in order to release the parking brake.
The PARK BRAKE light may flash while the parking
brake is being applied or released. This is normal for
this system.
If your vehicle needs towing or the parking brake will
not release, the towing operator will need to disconnect
the propshaft before towing your vehicle. See "Towing
Your Vehicle" in the Index.
If your vehicle has this
system, you will have a
knob located to the right of
the steering column.
