CHANGING A FLAT TIRE
If you get a flat tire when 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.
Have a flat serviced by an authorized
dealer to prevent damage to the system
sensors. See Tire Pressure Monitoring
System Precautions (page 560). Replace
the spare tire with a road tire as soon as
possible. When repairing or replacing the
flat tire, have the authorized dealer inspect
the system sensor for damage.
Note: The use of tire sealant could damage
your tire pressure monitoring system. Only
use in roadside emergencies.
Note: The tire pressure monitoring system
indicator light illuminates when the spare
tire is in use. To restore the full function of
the monitoring system, you must mount all
road wheels that come with tire pressure
monitoring sensors on this vehicle.
Dissimilar Spare Wheel and Tire
Assembly Information WARNING:
Failure to follow these
guidelines could result in an increased
risk of loss of vehicle control, injury or
death.
If you have a dissimilar spare wheel and
tire, the intent of the spare wheel is for
temporary use only. This means that if you
need to use it, replace it as soon as
possible with a road wheel and tire
assembly that is the same size and type
as the road tires and wheels originally
provided by Ford. We define a dissimilar spare wheel and tire
assembly as a spare wheel and tire
assembly that is different in brand, size or
appearance from the road tires and
wheels.
Full-size dissimilar spare
When driving with the full-size dissimilar
spare wheel and tire assembly, do not:
•
Exceed
70 mph (113 km/h).
• Use more than one dissimilar spare
wheel and tire assembly at a time.
• Use snow chains on the end of the
vehicle with the dissimilar spare wheel
and tire assembly.
Engage any four-wheel drive mode. See
Four-Wheel Drive Limitations (page 292).
The usage of a full-size dissimilar spare
wheel and tire assembly can lead to
impairment of the following:
• Handling, stability and braking
performance.
• Comfort and noise.
• Ground clearance and parking at curbs.
• Winter weather driving capability.
• Wet weather driving capability.
• Four-wheel drive capability.
When driving with the full-size dissimilar
spare wheel and tire assembly, give
additional caution to:
• Towing a trailer.
• Driving vehicles that come with a
camper body.
• Driving vehicles with a load on the
cargo rack.
Drive cautiously when using a full-size
dissimilar spare wheel and tire assembly
and seek service as soon as possible.

It is important to rely upon your dealership
to properly diagnose and repair your
vehicle.
We strongly recommend only using our
genuine or our authorized re-manufactured
replacement parts engineered for your
vehicle.
Additives and Chemicals
We do not recommend using chemicals or
additives not approved by us as part of
your vehicle
’s normal maintenance. Please
consult your warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a
normal operating characteristic and, by
itself, does not necessarily indicate a
concern or that the fluid needs to be
changed. Have discolored fluids that also
show signs of overheating or foreign
material contamination checked
immediately. Make sure to change the vehicle
’s oils and
fluids at the specified intervals or in
conjunction with a repair. Flushing is a
viable way to change fluid for many vehicle
sub-systems during scheduled
maintenance. It is critical that systems are
flushed only with new fluid that is the same
as that required to fill and operate the
system or using our approved flushing
chemical.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections. Check Every Month
The air filter restriction gauge. 1
The engine oil level.
Function of all interior and the exterior lights.
The tires including the spare for wear and proper pressure. The windshield washer fluid level.
The fuel and water separator. Drain if necessary or if indicated by the information display. 1
The holes and slots in the tail pipe to make sure they are functional and clear of debris. 1

Multi-Point Inspection
It is important to have the systems on your
vehicle regularly checked. This can help
identify potential issues and prevent major
problems. We recommend having the
following multi-point inspection performed
at every scheduled maintenance interval
to help make sure your vehicle keeps
running great. Multi-Point Inspection
