The park brake operates on the rear wheels of the vehicle.
Caution: Secure parking of the vehicle is dependent on
being on a hard and stable surface. The rear wheels must be
on a suitable surface to prevent vehicle movement.
The ignition control must on to release the park brake. First apply
pressure to the foot brake then pull on the park brake switch and
release. The symbol will go off to show the park brake has
been released.
Drive Away Release
Warning: Do not exit the vehicle with the engine
operating and the transmission in D (Drive) or R (Reverse).
Always select P (Park) before exiting the vehicle. If the
transmission is left in D (Drive) or R (Reverse) , the vehicle
can overcome the park brake and start to move.
With the park brake applied, select a forward or reverse gear and
press the throttle pedal. The park brake will release as the vehicle
moves forwards or backwards.
The park brake will not release when moving from stationary if a
vehicle door is open. In this case the park brake must be released
with the park brake switch.
Park Brake Operation While Moving
Warning: Repeated use of the park brake to slow the
vehicle, or driving the vehicle with the park brake applied
can cause serious damage to the brake system.

vehicle is moving. The park brake will only apply as normal once
the vehicle has stopped movement.
