2004 LINCOLN NAVIGATOR four wheel drive

• Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
• Using fuel blended with alcohol may lower fuel economy.
• Fuel economy may decrease with lower temperatures during the first
12 – 16 km (8 – 10 miles) of driving.
• Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
• Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
• Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
• Close windows for high speed driving.
EPA window sticker
The characteristics of the four wheel drive vehicle, like those of many,
similar competitive products, fit within categories where the fuel
economy labeling regulations do not apply. Therefore, the following
information applies only to the two wheel drive vehicle.
Every new vehicle should have the EPA window sticker. Contact your
dealer if the window sticker is not supplied with your vehicle. The EPA
window sticker should be your guide for the fuel economy comparisons
with other vehicles.
It is important to note the box in the lower left corner of the window
sticker. These numbers represent the range of fuel economy expected on
the vehicle under optimum conditions. Your fuel economy may vary
depending upon the method of operation and conditions.
EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission control components and a
catalytic converter which will enable your vehicle to comply with
applicable exhaust emission standards. To make sure that the catalytic
converter and other emission control components continue to work
properly:
• Use only the specified fuel listed.
• Avoid running out of fuel.
• Do not turn off the ignition while your vehicle is moving, especially at
high speeds.

6. Visually inspect the tires to make sure there are no nails or other
objects embedded that could poke a hole in the tire and cause an air
leak.
7. Check the sidewalls to make sure there are no gouges, cuts, bulges or
other irregularities.
Tire and wheel alignment
A bad jolt from hitting a curb or pothole can cause the front end of your
vehicle to become misaligned or damage to your tires. If your vehicle
seems to pull to one side, vibrate or shake when you ’ re driving, the
wheels may be out of alignment. Have a qualified technician at a
reputable repair facility check the wheel alignment periodically.
Wheel misalignment in the front or the rear can cause uneven and rapid
treadwear of your tires and should be corrected by a qualified technician
at a reputable repair facility. Front wheel drive (FWD) vehicles, and
those with independent front suspension require alignment of all four
wheels.
The tires should also be balanced periodically. An unbalanced tire and
wheel assembly may result in irregular tire wear.
Tire rotation
Rotating your tires at the recommended interval (as indicated in the
Service Maintenance Guide that comes with your vehicle) will help your
tires wear more evenly providing better tire performance and longer tire
life. Unless otherwise specified, rotate the tires approximately every
8,000 km (5,000 miles).

Sometimes irregular tire wear can be corrected by rotating the tires.
Note: If your tires show uneven wear ask a qualified technician at a
reputable repair facility to check for and correct any wheel misalignment,
tire imbalance or mechanical problem involved before tire rotation.
Tire wear
Measure and inspect the tire tread on all your tires periodically.
Advanced and unusual tire wear can reduce the ability of tread to grip
the road in adverse (wet, snowy, etc.) conditions. Visually check your
tires for uneven wear, looking for high and low areas or unusually
smooth areas. Also check for signs of tire damage.
When the tread is worn down to 4
mm (1/16th of an inch), tires must
be replaced to prevent your vehicle
from skidding and hydroplaning.
Built-in treadwear indicators, or
“ wear bars ” , which look like narrow
strips of smooth rubber across the
tread will appear on the tire when
