1When Stopped
In extremely cold temperatures, the parking brake
may freeze up if applied. If such temperatures are
expected, do not apply the parking brake but, if
parking on a slope, either turn the front wheels so
they will contact the curb if the vehicle rolls down the
slope or block the wheels to keep the vehicle from
moving. If you do not take either precaution, the
vehicle may roll unexpectedly, leading to a crash.
