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.
Note:If your vehicle is equipped with the tire pressure monitoring
system (TPMS), the indicator light will illuminate when the spare tire is
in use. To restore the full functionality of the monitoring system, all road
wheels equipped with tire pressure monitoring sensors must be mounted
on the vehicle.
If your vehicle is equipped with TPMS, have a flat serviced by an
authorized dealer in order to prevent damage to the TPMS sensors, refer
toTire pressure monitoring system (TPMS)in theTires, Wheels and
Loadingchapter.
WARNING:The use of tire sealants may damage your tire
pressure monitoring system (TPMS) and should not be used.
However, if you must use a sealant, the TPMS sensor and valve stem
on the wheel must be replaced by an authorized Ford dealer.

Note:Towing an ESOF 4x4 vehicle with the front wheels on the ground
without disengaging the front hubs may cause damage to the automatic
transmission.
Note:Towing a 4x2 or an ESOF 4x4 vehicle with the rear wheels on the
ground for more than 50 miles (80 km) and/or in excess of 35 mph
(56 km/h) may cause damage to the automatic transmission.
Note:On Dual Rear Wheel (DRW) vehicles, an outer rear wheel must be
removed prior to using a wheel lift wrecker.
Ford Motor Company produces a towing manual for all authorized tow
truck operators. Have your tow truck operator refer to this manual for
proper hook-up and towing procedures for your vehicle.
If the vehicle is towed by other means or incorrectly, vehicle
damage may occur.
Emergency towing
In case of a roadside emergency with a disabled vehicle (without access
to wheel dollies, car hauling trailer, or flatbed transport vehicle) your
vehicle (regardless of transmission powertrain configuration) can be flat
towed (all wheels on the ground) under the following conditions:
•Vehicle is facing forward so that it is being towed in a forward
direction.
•Place the transmission in N (Neutral). Refer toBrake-shift interlock
in theDrivingchapter for specific instructions if you cannot move the
gear shift lever into N (Neutral).

Engine fluid temperature management (except 6.8L V10)
Your vehicle has been designed to pull a trailer, but because of the added
load, the vehicle’s engine may temporarily reach higher temperatures
during severe operating conditions such as ascending a long or steep
grade while pulling a trailer in hot ambient temperatures.
At this time, you may notice your engine coolant temperature gauge
needle move toward the H and the POWER REDUCED TO LOWER
TEMP message may appear on the message center.
You may notice a reduction in the vehicle’s speed caused by reduced
engine power. Your vehicle has been designed to enter this mode if
certain high temperature/high load conditions take place in order to
manage the engine’s fluid temperatures. The amount of speed reduction
will depend on the vehicle loading, towing, grade, ambient temperature,
and other factors. If this occurs, there is no need to pull off the road.
The vehicle can continue to be driven while this message is active.
WARNING:To reduce the risk of collision and injury, be
prepared that the vehicle speed may reduce and the vehicle may
not be able to accelerate with full power until the fluid temperatures
reduce.
The air conditioning may also cycle on and off during severe operating
conditions to protect overheating of the engine. When the engine coolant
temperature decreases to a more normal operating temperature, the air
conditioning will turn on once again.
If you notice any of the following:
•the engine coolant temperature gauge moves fully into the red (hot)
area
•the coolant temperature warning light illuminates
•the service engine soon indicator illuminates
1. Pull off the road as soon as safely possible and place the vehicle in P
(Park).
2. Leave the engine running until the coolant temperature gauge needle
moves away from the H range. After several minutes, if this does not
happen, follow the remaining steps.
3. Turn the engine off and wait for it to cool before checking the coolant
level.
