When you are doing this check, your vehicle could begin to move. You or others could be
-
b
injured and property could be damaged. Make sure there is room in front of your vehicle
in case it begins to roll. Be ready to apply the regular brake at once should the vehicle begin to
move.
Park on a fairly steep hill, with the vehicle facing downhill. Keeping your foot on the regular
brake, set the parking brake.
To check the parking brake: With the engine running and the transaxle in
N
(Neutral), slowly
remove foot pressure from the regular brake pedal. Do this until the vehicle is held by the
parking brake only.
To check the
P
(Park) mechanism's holding ability: Shift to
P (Park).
Then release all brakes.
At least every spring, use plain water to flush any corrosive materials from the underbody. Take
care to clean thoroughly any areas where mud
and
other debris can collect.
