3. To remove the wiper blade from the wiper
arm, grasp the bottom end of the wiper
blade nearest to wiper arm with your right
hand. With your left hand hold the wiper
arm as you pull the wiper blade away from
the wiper arm past its stop far enough to
unsnap the wiper blade pivot pin from the
receptacle on the end of the wiper arm.
NOTE:
Resistance will be accompanied by an
audible snap.
4. Still grasping the bottom end of the wiper
blade, move the wiper blade upward and
away from the wiper arm to disengage.
5. Gently lower the tip of the wiper arm onto
the glass.
Installing The Rear Wiper
1. Lift the rear wiper arm pivot cap away
from the glass to allow the rear wiper
blade to be raised off of the glass.NOTE:
The rear wiper arm cannot be fully raised
off the glass unless the wiper arm pivot
cap is unsnapped first. Attempting to fully
raise the rear wiper arm without unsnap-
ping the wiper arm pivot cap may damage
the vehicle.
2. Lift the rear wiper arm fully off the glass.
3. Insert the wiper blade pivot pin into the
opening on the end of the wiper arm. Grab
the bottom end of the wiper arm with one
hand, and press the wiper blade flush with
the wiper arm until it snaps into place.
4. Lower the wiper blade onto the glass and
snap the wiper arm pivot cap back into
place.
Cooling System
WARNING!
• You or others can be badly burned by hot
engine coolant (antifreeze) or steam
from your radiator. If you see or hear
steam coming from under the hood, do
not open the hood until the radiator has

WARNING!
had time to cool. Never open a cooling
system pressure cap when the radiator
or coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts auto-
matically and may start at any time,
whether the engine is running or not.
• When working near the radiator cooling
fan, disconnect the fan motor lead or
turn the ignition to the OFF mode. The
fan is temperature controlled and can
start at any time the ignition is in the ON
mode.
Engine Coolant Checks
Check the engine coolant (antifreeze) protec-
tion every 12 months (before the onset of
freezing weather, where applicable). If the
engine coolant (antifreeze) is dirty, the sys-
tem should be drained, flushed, and refilled
with fresh OAT coolant (conforming to
MS.90032) by an authorized dealer. Check
the front of the A/C condenser for any accu-mulation of bugs, leaves, etc. If dirty, clean
by gently spraying water from a garden hose
vertically down the face of the condenser.
Check the engine cooling system hoses for
brittle rubber, cracking, tears, cuts, and
tightness of the connection at the coolant
recovery bottle and radiator. Inspect the en-
tire system for leaks. DO NOT REMOVE THE
COOLANT PRESSURE CAP WHEN THE
COOLING SYSTEM IS HOT.
RAISING THE VEHICLE
In the case where it is necessary to raise the
vehicle, go to an authorized dealer or service
station.
TIRES
Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to
the safe and satisfactory operation of your
vehicle. Four primary areas are affected by
improper tire pressure:
• Safety and Vehicle Stability• Economy
• Tread Wear
• Ride Comfort
Safety
WARNING!
• Improperly inflated tires are dangerous
and can cause collisions.
• Underinflation increases tire flexing and
can result in overheating and tire failure.
• Overinflation reduces a tire's ability to
cushion shock. Objects on the road and
chuckholes can cause damage that re-
sult in tire failure.
• Overinflated or underinflated tires can
affect vehicle handling and can fail sud-
denly, resulting in loss of vehicle control.
• Unequal tire pressures can cause steer-
ing problems. You could lose control of
your vehicle.
• Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.
