service FORD SUPER DUTY 2007 1.G Special Off-Road Package Supplement Manual

WHEELS
Your vehicle may be equipped with two-piece bolt-together beadlock
rims. Beadlock rims allow the tires to survive operating at lower air
pressure which provide greater traction due to the larger tire-to-ground
contact area during slow, off-road operation. Always reinflate the tires to
the tire manufacturer's recommendations when no longer in slow,
off-road driving conditions. The beadlock also acts as a safety device
ensuring that the tire does not unseat from the rim or rotate on the
wheel when tire pressure is reduced, while also preventing the entry of
foreign objects, debris or water into the tire's air chamber.
Note:The wheel/tire assemblies should be serviced only by trained
personnel who have read and understand the wheel
assembly/disassembly information contained within theWorkshop
Manual.
TIRES
Each tire is equipped with a Variable Function Insert (VFI) which is
mounted into the tire. The VFI insert and tire are then fitted around the
beadlock rim assembly, providing a higher level of tire protection due to
the dense rubber material in the tire assembly and maximum all-terrain
mobility.
SNOW CHAINS
Tire chains cannot be used on vehicles equipped with M/TR tires.
ON-BOARD AIR SYSTEM (IF EQUIPPED)
Your vehicle may be equipped with an on-board air system which has
been designed to provide compressed air for multiple uses, including the
addition of air to the vehicle's tires. The system uses a 25 ft. (7.6m)
length of air hose equipped with a clamp-on style air chuck. When not in
use, this hose is secured to the floor of the truck. A compressor,
mounted to the frame under the truck on the passenger side frame rail,
is included along with an air reservoir on the driver side. When the
compressor is on, the output pressure at the air tank is limited to 80 psi
(552 kPa).

DDM
Displays current CTIS status and
alerts.
1.TERRAIN display:
²HY (Highway) for operation on
improved surfaces
²CC (Cross Country) for operation
on secondary roads
²SS (Sand) for operation on sand,
trails and unimproved surfaces
²E (Emergency) for selection of extremely low tire pressures to help
free stuck vehicle or to traverse bad terrain
Dashes displayed in DDM Terrain display
²CTIS system fault
²CTIS has shut off at least one channel due to fault tolerance
²System may periodically check to see if fault still exists
²Operation may be allowed on unaffected channels
²Check tires for proper pressure and get service at earliest opportunity
2.LOAD bar graph display:
²Off: Unloaded
²On: Loaded
3.Channel display:
²FRT: Front axle
²RR: Rear axle
When the terrain channel is flashing, the CTIS is working to achieve
pressures that are appropriate with the indicated terrain or checking
pressure.
When the terrain channel is solid, the tires are at the appropriate
pressure, the CTIS is in maintenance mode and the wheel valves are
closed.
4.OVERSPEED
²Flashing or buzzer activated:Vehicle speed has exceeded the
programmed speed limit for the current tire pressure.
