310 STARTING AND OPERATING
Parking Brake Release
Be sure the parking brake is firmly set when parked and
the gear shift lever is in the PARK position. When
parking on a hill you should apply the parking brake
before placing the gear shift lever in PARK, otherwise the
load on the transmission locking mechanism may make it
difficult to move the selector out of PARK.
WARNING!
• Always fully apply the parking brake when
leaving your vehicle, or it may roll and cause
damage or injury. Also be certain to leave an
automatic transmission in Park, a manual trans-
mission in Reverse or First gear. Failure to do so
may allow the vehicle to roll and cause damage
or injury.
• Never leave children alone in a vehicle. Leaving
children in a vehicle unattended is dangerous
for a number of reasons. A child or others could
be seriously or fatally injured. Don't leave the
keys in the ignition. A child could operate
power windows, other controls, or move the
vehicle.
• Be sure the parking brake is fully disengaged
before driving, failure to do so can lead to brake
problems due to excessive heating of the rear
brakes.
