Each daybefore 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 everyfew weeks
(including spare). Safe operation
requires tires that are neither
underinflated nor a vehicle which is
overloaded.
Periodicallyinspect the tire treads and remove stones, nails, glass or
other objects that maybe wedged in the tread grooves. Check for holes
or cuts that maypermit 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 reasonablysafe, predictable performance
whether loaded or emptyand durable load carrying capability. For this
reason, Ford Motor Companystronglyrecommends that you do not make
modifications such as adding or removing parts (such as lift kits or
stabilizer bars) or byusing replacement parts not equivalent to the
original factoryequipment.
Anymodifications to a vehicle that raise the center of gravitycan make
it more likelythe vehicle will roll over as a result of a loss of control.
Ford Motor Companyrecommends that caution be used with anyvehicle
equipped with a high load or device (such as ladder racks or pickup box
cover).
Failure to maintain your vehicle properlymayvoid the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adverselyaffect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavyoff-road usage.
