Lubricant Selection
Use only the manufacturer's recommended
fluid. Refer to "Fluids And Lubricants" in "Tech-
nical Specifications" for further information.
Fluid Level Check
Visually inspect the unit at each oil change for
leakage. If leakage is detected, Check the fluid
level by removing the fill plug. The fluid level
should be maintained between the bottom of the
fill hole to 1/8 inch (4 mm) below the fill hole.
Add fluid, if necessary, to maintain the proper
level.
Frequency Of Fluid Change
Refer to the "Service and Warranty Handbook"
for the proper maintenance intervals.

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 result
in tire failure.
• Overinflated or underinflated tires can af-
fect vehicle handling and can fail suddenly,
resulting in loss of vehicle control.
WARNING! (Continued)
• Unequal tire pressures can cause steering
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.
• Always drive with each tire inflated to the
recommended cold tire inflation pressure.
Both under-inflation and over-inflation affect the
stability of the vehicle and can produce a feeling
of sluggish response or over responsiveness in
the steering.
NOTE:
• Unequal tire pressures from side to side
may cause erratic and unpredictable
steering response.
• Unequal tire pressure from side to side
may cause the vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling resis-
tance resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause
abnormal wear patterns and reduced tread life,
resulting in the need for earlier tire replacement.
