What you should know about fail-safe cooling (if equipped)
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The “fail-safe” distance depends on ambient temperatures, vehicle load
and terrain.
How fail-safe cooling works
If the engine begins to overheat:
• The engine coolant temperature
gauge will move to the red (hot)
area.
• The and symbol will
illuminate.
• The Service engine soon
indicator light will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When this occurs the vehicle will still operate. However:
• The engine power will be limited.
• The air conditioning system will be disabled.
Continued operation will increase the engine temperature and the engine
will completely shut down, causing steering and braking effort to
increase.
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to a service facility as soon as possible to minimize engine
damage.
When fail-safe mode is activated
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. The vehicle will not be able to maintain high-speed
operation and the engine will run rough. Remember that the engine is
capable of completely shutting down automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to a service facility.
3. If this is not possible, wait a short period for the engine to cool.

engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.
CHECKING AND ADDING POWER STEERING FLUID
Check the power steering fluid.
Refer to the scheduled maintenance
guide for the service interval
schedules. If adding fluid is
necessary, use only MERCON AT F.
Check the fluid level when it is at ambient temperature, 20° – 80° F (-7°
– 25° C):
1. Check the fluid level on the dipstick. It should be between the arrows in
the FULL COLD range. Do not add fluid if the level is within this range.
2. If the fluid level is low. Add fluid to bring fluid level up to be between
the arrows in the FULL COLD range.
3. Start the engine.
4. While the engine idles, turn the steering wheel left and right several times.
5. Turn the engine off.
6. Recheck the fluid level on the dipstick. Do not add fluid if the level is
between the arrows in the FULL COLD range.
7. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the FULL COLD range. Be sure to put the
dipstick back in the reservoir.

slip axles. Ford design rear axles contain a synthetic lubricant that does
not require changing unless the axle has been submerged in water. Dana
rear axles also contain a synthetic lubricant but do require a change.
Refer to your Scheduled Maintenance Guide for change intervals on
Dana rear axles. 2
Ensure the correct automatic transmission fluid is used. Transmission
fluid requirements are indicated on the end of the dipstick. Check the
container to verify the fluid being added is of the correct type. Refer to
your Scheduled Maintenance Guide to determine the correct service
interval.
MERCON , MERCON V and MERCON SP are not
interchangeable. DO NOT mix MERCON , MERCON V and
MERCON SP. Use of dual usage fluids in an automatic
transmission application requiring MERCON SP may cause
transmission damage. Use of a transmission fluid other than the
recommended fluid may cause transmission damage.
