tires LINCOLN BLACKWOOD 2003 User Guide

Avoid sudden braking as well. Although a 4WD vehicle may accelerate
better than a two-wheel drive vehicle in snow and ice, it won’t stop any
faster, because as in other vehicles, braking occurs at all four wheels. Do
not become overconfident as to road conditions.
Make sure you allow sufficient distance between you and other vehicles
for stopping. Drive slower than usual and consider using one of the lower
gears. In emergency stopping situations, avoid locking of the wheels. Use
a“squeeze”technique, push on the brake pedal with a steadily increasing
force which allows the wheels to brake yet continue to roll so that you
may steer in the direction you want to travel. If you lock the wheels,
release the brake pedal and repeat the squeeze technique. If your vehicle
is equipped with a Four Wheel Anti-Lock Brake System (ABS), apply the
brake steadily. Do not“pump”the brakes. Refer to theBrakessection of
this chapter for additional information on the operation of the anti-lock
brake system.
Never drive with chains on the front tires of 4WD vehicles without also
putting them on the rear tires. This could cause the rear to slide and
swing around during braking.
Tires, Replacement Requirements
Do not use a size and type of tire and wheel other than that
originally provided by Ford Motor Company because it can affect
the safety and performance of your vehicle, which could result in an
increased risk of loss of vehicle control, vehicle rollover, and/or serious
personal injury or death.
Make sure all tires and wheels on the vehicle are of the same size, type,
tread design, brand and load-carrying capacity. If you have questions
regarding tire replacement, see an authorized Ford or Lincoln/Mercury
dealer.
If you nevertheless decide to equip your 4WD for off-road use with tires
larger than what Ford Motor Company recommends, you should not use
these tires for highway driving.
If you use any tire/wheel combination not recommended by Ford Motor
Company, it may adversely affect vehicle handling and could cause
steering, suspension, axle or transfer case failure.
Do not use“aftermarket lift kits”or other suspension modifications,
whether or not they are used with larger tires and wheels.
These“aftermarket lift kits”could adversely affect the vehicle’s handling
characteristics, which could lead to loss of vehicle control or rollover and
serious injury.

Tires can be damaged during off-road use. For your safety, tires that are
damaged should not be used for highway driving because they are more
likely to blow out or fail.
You should carefully observe the recommended tire inflation pressure
found on the safety compliance certification label attached to the left
front door lock facing or door latch post pillar. Failure to follow tire
pressure recommendations can adversely affect the way your vehicle
handles. Do not exceed the Ford Motor Company recommended pressure
even if it is less than the maximum pressure allowed for the tire.
Each day before you drive, check
your tires. If one looks lower than
the others, use a tire gauge to check
pressure of all tires, and adjust if
required. Check tire pressure with a
tire gauge every few weeks
(including spare). Safe operation
requires tires that are neither
underinflated nor a vehicle which is
overloaded.
Periodically inspect the tire treads and remove stones, nails, glass or
other objects that may be wedged in the tread grooves. Check for holes
or cuts that may permit air leakage from the tire and make necessary
repairs.
Inspect the tire side walls for cuts, bruises and other damage. If internal
damage to the tire is suspected, have the tire demounted and inspected
in case it needs to be repaired or replaced.
Maintenance and Modifications
The suspension and steering systems on your vehicle have been designed
and tested to provide both reliable and reasonably predictable
performance whether loaded or empty and durable load carrying
capability. For this reason, Ford Motor Company strongly recommends
that you do not make modifications such as adding or removing parts
(such as lift kits or stabilizer bars) or by using replacement parts not
equivalent to the original factory equipment.
Any modifications to a vehicle that raise the center of gravity can make
it more likely the vehicle will roll over as a result of a loss of control.
Ford Motor Company recommends that caution be used with any vehicle
equipped with a high load or device (such as ladder racks or pickup box
cover).

•GCWR (Gross Combined Weight Rating):Maximum allowable
combined weight of towing vehicle (including occupants and cargo)
and the loaded trailer.
•Maximum Trailer Weight Rating:Maximum weight of a trailer the
vehicle is permitted to tow. The maximum trailer weight rating is
determined by subtracting the vehicle curb weight for each
engine/transmission combination, any required option weight for trailer
towing and the weight of the driver from the GCWR for the towing
vehicle.
•Maximum Trailer Weight:Maximum weight of a trailer the loaded
vehicle, including occupants and cargo, is permitted to tow. It is
determined by subtracting the weight of the loaded trailer towing
vehicle from the GCWR for the towing vehicle.
•Trailer Weight Range:Specified range of trailer weight from zero to
the maximum trailer weight rating.
Remember to figure in the tongue load of your loaded trailer when
figuring the total weight.
The Safety Certification Label, located on the driver’s door pillar, lists
vehicle weight rating limitations. Before adding any additional equipment,
refer to these limitations.
Always ensure that the weight of occupants, cargo and equipment is
within the weight limitations, including both gross vehicle weight and
front and rear gross axle weight rating limits.
Note:Do not exceed the GVWR or the GAWR specified on the
certification label.
Exceeding any vehicle weight rating limitation could result in
serious damage to the vehicle, loss of vehicle control, vehicle
rollover, and/or personal injury.
Do not use replacement tires with lower load carrying capacities than the
originals because they may lower the vehicle’s GVWR and GAWR
limitations. Replacement tires with a higher limit than the originals do
not increase the GVWR and GAWR limitations.

Special loading instructions for owners of pickup trucks and
utility-type vehicles
For important information regarding safe operation of this type
of vehicle, see thePreparing to drive your vehiclesection in
this chapter.
Loaded vehicles may handle differently than unloaded vehicles.
Extra precautions, such as slower speeds and increased stopping
distance, should be taken when driving a heavily loaded vehicle.
Your vehicle can haul more cargo and people than most passenger cars.
Depending upon the type and placement of the load, hauling cargo and
people may raise the center of gravity of the vehicle.
Calculating the load your vehicle can carry/tow
1. Use the appropriate maximum GCWR chart (in theTrailer Towing
section in this chapter) for your type of engine and rear axle ratio.
2. Weigh your vehicle without cargo. To obtain correct weights, take your
vehicle to a shipping company or an inspection station for trucks.
3. Subtract your loaded weight from the maximum GCWR in the chart.
This is the maximum trailer weight your vehicle can tow. It must be
below the maximum trailer weight shown in the chart.
TRAILER TOWING
Your vehicle may tow a class I, II or III trailer provided the maximum
trailer weight is less than or equal to the maximum trailer weight listed
for your engine and rear axle ratio on the following charts.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components carefully periodically during, and after any towing operation.
Exceeding the maximum GCWR could result in extensive damage
to your vehicle and personal injury.
Do not exceed the GVWR or the GAWR specified on the
certification label.

2WD vehicles (with automatic transmissions):
•Place the transmission in N (Neutral)
•Maximum speed is 56 km (35 mph)
•Maximum distance is 80 km (50 miles)
If a distance of 80 km (50 miles) or a speed of 56 km (35 mph) must be
exceeded, the drive shaft will have to be removed before the vehicle is
towed.
Ford recommends the driveshaft be removed/installed only by a qualified
technician. See your local dealer for driveshaft removal/installation.
Improper removal/installation of the driveshaft can cause
transmission fluid loss, damage to the driveshaft and internal
transmission components.
4WD vehicles electronic shift transfer case (with automatic
transmissions):
4x4 vehicles with electronic shift on the fly cannot be towed with any
wheels on the ground.
SNOWPLOWING
Ford recommends the following specifications for low speed, personal
use snow removal:
•F-150 4x4 (except F-150 Supercrew, Lightning and Harley-Davidson
models)
•5.4L engine
•Heavy-duty service package
•Super engine cooling
•Heavy-duty front suspension package
•Automatic transmission with auxiliary automatic transmission fluid
cooling
•All-terrain tires
•Limited slip and optional axle ratio.
Do not install a snowplow and plow with your vehicle until it has been
driven at least 800 km (500 miles).
Driving

Installing the snowplow
Read the following instructions before installing a snowplow:
•Front GAWR must not exceed 63% of the GVW. Add ballast weight to
the back of the vehicle, if necessary. Refer to the Safety Compliance
Certification Label to find your vehicle’s front GAWR.
•The Front Axle Accessory Reserve Capacity and the TARC listed on
the bottom right of the Safety Compliance Certification Label will
determine whether or not the addition of a snowplow will overload
your vehicle.
•The weight of the snowplow and supporting components distributed to
the front axle must not exceed the Front Axle Accessory Reserve
Capacity.
•The total weight of the snowplow and aftermarket equipment must
not exceed the TARC.
•The weight of the installed snowplow and aftermarket equipment must
not load the vehicle beyond the GAWR (front/rear) and GVWR listed
on the Safety Compliance Certification Label.
•The total weight of the snowplow and aftermarket equipment must be
considered part of the payload and must not exceed the GCWR for
towing.
•Federal and most local regulations require additional exterior lamps
for snowplow-equipped vehicles. Consult your dealer for additional
information.
•Tires have their maximum inflation pressure and associated load rating
imprinted on the tire sidewall. This pressure may or may not be the
same as that shown as recommended on the vehicle. The vehicle
operator may have to adjust the tire inflation pressure to
accommodate the snowplow and payload. Consult your dealer or
equipment installer for help with proper inflation pressures.
•Federal and some local regulations require additional exterior lamps
for snowplow-equipped vehicles. Consult your dealer for additional
information.
•After installing a snowplow to the vehicle, ensure the vehicle’s front
toe alignment and front ride height are within specification (reset if
required). These specifications are located in the vehicle’s Workshop
Manual.
Note:Do not exceed the GVWR or the GAWR specified on the
certification label.

•Shift transfer case to 4L (4WD Low) when plowing in small areas at
speeds below 8 km/h (5 mph).
•Shift transfer case to 4H (4WD High) when plowing larger areas or
light snow at higher speeds. Do not exceed 24 km/h (15 mph).
•Do not shift the transmission from a forward gear to R (Reverse) until
the engine is at idle and the wheels are stopped.
•If the vehicle is stuck, shift the transmission in a steady motion
between forward and reverse gears. Do not rock the vehicle for more
than a few minutes. The transmission and tires may be damaged or
the engine can overheat.
Do not rock the vehicle if the engine is not at operating
temperature. Do not rock the vehicle for more than a minute. The
transmission and tires may be damaged or the engine may
overheat.
Do not spin the wheels at over 35 mph (55 km/h). The tires may
fail and injure a passenger or bystander.

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Harley-Davidson vehicles are equipped with a spare tire with a different
speed rating than the road tires. It is not recommended that you exceed
112 km/h (70 mph) when the spare tire is in use. Though the spare tire
is rated for 112 km/h (70 mph), always obey the local speed limits.
Roadside Emergencies
184

The use of tire sealants is not recommended and may
compromise the integrity of your tires. The use of tire sealants
may also affect your tire pressure monitoring system (if equipped).
Spare tire information
Your vehicle is equipped with a spare tire that may be used as a spare or
a regular tire. The spare tire wheel may not match the road wheel, and is
not equipped with wheel trim. The wheel trim from the wheel/tire may
be used on the spare if the wheels match.
If your vehicle is equipped with 4WD, a spare tire of a different
size than the road tires should not be used. Use of such a tire
could result in damage to driveline components and an increased risk
of loss of vehicle control, vehicle rollover, personal injury or death.
If your vehicle is equipped with a tire pressure monitoring
system, refer to Tire Pressure Monitoring System (if equipped)
in the Maintenance and specifications section for important information
before changing your tires. If the tire pressure monitoring system
becomes damaged, it will no longer function.
Location of the spare tire and tools
The spare tire and tools for your vehicle are stowed in the following
locations:
Tool Location
Spare tire Under the vehicle, just forward of
the rear bumper
Jack, lug nut wrench Regular cab: Under the seat on the
passenger side
Super Cab: Under the front or rear
seat on the passenger side
Super Crew cab: In the passenger
side rear storage compartment
Roadside Emergencies
185

•Anticipate stopping; slowing down may eliminate the need to stop.
•Sudden or hard accelerations may reduce fuel economy.
•Slow down gradually.
•Driving at reasonable speeds (traveling at 88 km/h [55 mph] uses 15%
less fuel than traveling at 105 km/h [65 mph]).
•Revving the engine before turning it off may reduce fuel economy.
•Using the air conditioner or defroster may reduce fuel economy.
•You may want to turn off the speed control in hilly terrain if
unnecessary shifting between third and fourth gear occurs.
Unnecessary shifting of this type could result in reduced fuel
economy.
•Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
•Resting your foot on the brake pedal while driving may reduce fuel
economy.
•Combine errands and minimize stop-and-go driving.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toLubricant specificationsin
this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle scheduled maintenance guide.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•To maximize the fuel economy, drive with the tonneau cover installed
(if equipped).
