CHANGING A FLAT TIRE
If you get a flat tire while driving:
•do not brake heavily.
•gradually decrease the vehicle’s speed.
•hold the steering wheel firmly.
•slowly move to a safe place on the side of the road.
Your vehicle may be equipped with a conventional spare tire that is
different in one or more of the following: type, brand, size, speed rating
and tread design. If this is the case, this dissimilar spare tire is still rated
for your vehicle loads (GAWR and GVWR).

Roadside Emergencies

•Do not use household or glass cleaners as these may damage the
finish of the instrument panel, interior trim and cluster lens.
Do not use chemical solvents or strong detergents when cleaning
the steering wheel or instrument panel to avoid contamination of
the airbag system.
If a staining liquid like coffee/juice has been spilled on the instrument
panel or on interior trim surfaces, clean as follows:
1. Wipe up spilled liquid using a clean white cotton cloth.
2. Apply Motorcraft Deluxe Leather and Vinyl Cleaner (ZC-11-A) [In
Canada use Motorcraft Multi-Purpose Cleaner (CXC-101)] to the wiped
area and spread around evenly.
3. Apply more Motorcraft cleaner to a clean white cotton cloth and press
the cloth onto the soiled area–allow this to set at room temperature for
30 minutes.
4. Remove the soaked cloth, and if it is not soiled badly, use this cloth to
clean the area by using a rubbing motion for 60 seconds.
5. Following this, wipe area dry with a clean white cotton cloth.
INTERIOR
For fabric, carpets, cloth seats and safety belts:
•Remove dust and loose dirt with a vacuum cleaner.
•Remove light stains and soil with Motorcraft Professional Strength
Carpet & Upholstery Cleaner (ZC-54).
•If grease or tar is present on the material, spot-clean the area first
with Motorcraft Spot and Stain Remover (ZC-14).
•If a ring forms on the fabric after spot cleaning, clean the entire area
immediately (but do not oversaturate) or the ring will set.
•Do not use household cleaning products or glass cleaners, which can
stain and discolor the fabric and affect the flame retardant abilities of
the seat materials.
Do not use cleaning solvents, bleach or dye on the vehicle’s
seatbelts, as these actions may weaken the belt webbing.

How fail-safe cooling works
If the engine begins to overheat:
•The engine coolant temperature
gauge will move to the red (hot)
area.
•The message center will indicate
the engine is overheating.
•TheCheck engineindicator
(
) 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.
4. Check the coolant level and replenish if low.
Never remove the coolant reservoir cap while the engine is
running or hot.
5. Re-start the engine and take your vehicle to a service facility.

4. Driving through deep water - the electrical system may be wet.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel, properly tightening the fuel cap or letting the
electrical system dry out. After three driving cycles without these or any
other temporary malfunctions present, the
indicator should stay off
the next time the engine is started. A driving cycle consists of a cold
engine startup followed by mixed city/highway driving. No additional
vehicle service is required.
If the
indicator remains on, have your vehicle serviced at the first
available opportunity. Although some malfunctions detected by the
OBD-II may not have symptoms that are apparent, continued driving
with the
indicator on can result in increased emissions, lower fuel
economy, reduced engine and transmission smoothness, and lead to more
costly repairs.
Readiness for Inspection/Maintenance (I/M) testing
In some localities, it may be a legal requirement to pass an I/M test of
the on-board diagnostics system. If the
indicator is on, refer to the
description in the Warning lights and chimes section of the Instrument
Cluster chapter. Your vehicle may not pass the I/M test with the
indicator on.
If the vehicle’s powertrain system or its battery has just been serviced,
the on-board diagnostics system is reset to a “not ready for I/M test”
condition. To ready the on-board diagnostics system for I/M testing, a
minimum of 30 minutes of city and highway driving is necessary as
described below:
•First, at least 10 minutes of driving on an expressway or highway.
•Next, at least 20 minutes driving in stop-and-go, city-type traffic with
at least four idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.
POWER STEERING FLUID
Check the power steering fluid. Refer to thescheduled maintenance
informationfor the service interval schedules. If adding fluid is
necessary, use only MERCON

Owner Guide Supplement.
Check the fluid level when it is at ambient temperature, 20°F–80°F
(-7°C–25°C):
1. Check the fluid level in the reservoir. It should be between the MIN
and MAX 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 MIN and MAX 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 in the reservoir. Do not add fluid if the level is
between the MIN and MAX range.
7. If the fluid is low, add fluid in small amounts, continuously checking
the level until it is between the MIN and MAX range. Be sure to put the
cap back on the reservoir.
