Mechanism Check
Warning
When you are doing this check,
the vehicle could begin to move.
You or others could be injured
and property could be damaged.
Make sure there is room in front
of the 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's
holding ability: With the engine
running and the transmission 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:
With the engine running, shift to
P (Park). Then release the
parking brake followed by the
regular brake.
Contact your dealer if service is

Wiper Blade Replacement

Front Wiper Blade
Windshield wiper blades should be
inspected for wear or cracking. See
Maintenance Schedule 0 321.
Replacement blades come in
different types and are removed in
different ways. For the proper type
and size, see Maintenance
Replacement Parts 0 331.
To replace the wiper blade
assembly:
1. Pull the windshield wiper
assembly away from the
windshield.
2. Squeeze the tabs on each side
of the wiper blade assembly
and slide the assembly off the
end of the wiper arm.
3. Install the new blade onto the
arm connector and make sure
the tabs are fully set in the
locked position.
Allowing the wiper blade arm to
touch the windshield when no
wiper blade is installed could
damage the windshield. Any
damage that occurs would not
be covered by your warranty.
Do not allow the wiper blade
arm to touch the windshield.
