bags (front or side) are operational.
If the light fails to illuminate,
continues to flash or remains on,
have the system serviced immediately.
Charging system
Illuminates when the battery is not
charging properly.
Engine oil pressure (if equipped)
Illuminates when the oil pressure
falls below the normal range. Check
the oil level and add oil if needed.
Refer toEngine oilin the
Maintenance and specificationschapter.
Traction ControlAdvancTrac active (if equipped)
Illuminates when the Traction
Control
system is active. It will be
lit for a minimum of four seconds or
for the duration of the Traction

•Optional instrument cluster
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level the gauge indication
will not be accurate. If the gauge enters the red section, the engine
coolant andCheck Engine/Service Engine Soonindicators illuminate,
refer toWhat you should know about fail-safe coolingin the
Maintenance and specificationschapter.
Engine oil pressure gauge (if equipped)
Indicates engine oil pressure. At
normal operating temperature, the
needle will be in the normal range
(the area between the “L” and “H”);
if the needle goes below the normal
range, stop the vehicle as soon as
safely possible and switch off the
engine immediately. Check the oil
level. Add oil if needed (refer to
Engine oilin theMaintenance
and specificationschapter). If the
oil level is correct, have your vehicle checked at your dealership or by a
qualified technician.

WINDSHIELD WIPER/WASHER CONTROLS
Rotate the windshield wiper control
to the desired interval, low or high
speed position.
The bars of varying length are for
intermittent wipers. When in this
position rotate the control upward
for fast intervals and downward for
slow intervals.
Push the end of the stalk to activate
washer. Push and hold for a longer
wash cycle.
Windshield wiper/washer features
The exterior lamps will illuminate after 10–20 second delay when the
ignition is ON and the windshield wiper control is in the LO or HI
position.
The lights will remain on for 30 seconds after the wipers are turned off.
Maintenance and care of windshield wiper blades
Check the wiper blades for wear at least twice a year or when they seem
less effective. Substances such as tree sap, road salt, oil film and some
hot wax treatments used by commercial car washes reduce the
effectiveness of wiper blades.
Operation of the wipers on dry glass for long periods of time may cause
deterioration of the wiper blades. Always use washer fluid when using
the wipers to remove salt or dirt from a dry windshield. Avoid using the
blades to remove frost or ice from the windshield. If the wiper blades are
frozen to the windshield, loosen the wiper blades before operating the
wipers to prevent damage to the wiper system.
It the windshield is not clear after using the windshield washer wiper
system, or if the wiper blades chatter, streak or smear when operating, it
is possible that wax, road salt or oil film may be on the windshield or the
wiper blades. Refer toCleaning window and wiper bladesin the
Cleaningchapter.
Changing the wiper blades
To make changing the wiper blades easy, turn the ignition to ACC, then
turn the wipers on. When the wipers reach the vertical position, turn the
ignition to LOCK.

WINDSHIELD WASHER FLUID
Add fluid to fill the reservoir if the
level is low. In very cold weather, do
not fill the reservoir completely.
Only use a washer fluid that meets
Ford specification WSB-M8B16–A2.
Refer toLubricant specifications
in this chapter.
State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle’s paint finish, wiper blades or washer system.
If you operate your vehicle in temperatures below 4.5° C
(40° F), use washer fluid with antifreeze protection. Failure to
use washer fluid with antifreeze protection in cold weather could result
in impaired windshield vision and increase the risk of injury or
accident.
Note:Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling system
components.
ENGINE OIL
Checking the engine oil
Refer to the scheduled maintenance guide for the appropriate intervals
for checking the engine oil.
1. Make sure the vehicle is on level ground.
2. Turn the engine off and wait up to 10 minutes for the oil to drain into
the oil pan.
3. Set the parking brake and ensure the gearshift is securely latched in P
(Park).
4. Open the hood. Protect yourself from engine heat.

•If required, add engine oil to the
engine. Refer toAdding engine
oilin this chapter.
•Do not overfill the engine
with oil. Oil levels above this
mark may cause engine
damage.If the engine is
overfilled, some oil must be
removed from the engine by a
qualified service technician.
7. Put the indicator back in and ensure it is fully seated.
Adding engine oil
1. Check the engine oil. For instructions, refer toChecking the engine
oilin this chapter.
2. If the engine oil level is not within the normal operating range, add
only certified engine oil of the recommended viscosity. Remove the
engine oil filler cap and use a funnel to pour the engine oil into the
opening.
3. Recheck the engine oil level. Make sure the oil level is not above the
normal operating range on the engine oil level indicator (dipstick).
4. Install the indicator and ensure it is fully seated.
5. Fully install the engine oil filler cap by turning the filler cap clockwise
until three clicks can be heard.
To avoid possible oil loss, DO NOT operate the vehicle with the
engine oil level indicator and/or the engine oil filler cap removed.

•Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized
standards for disposal. Call your
local authorized recycling center
to find out more about recycling
automotive batteries.
ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should be checked at the
mileage intervals listed in the scheduled maintenance guide. The coolant
concentration should be maintained at 50/50 coolant and distilled water,
which equates to a freeze point of -36° C (-34° F). Coolant concentration
testing is possible with a hydrometer or antifreeze tester (such as the
Rotunda Battery and Antifreeze Tester, 014–R1060). The level of coolant
should be maintained at the “cold full” of “cold fill range” level in the
coolant reservoir. If the level falls below, add coolant per the instructions
in theAdding engine coolantsection.
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50–50 mixture of coolant and water provides the following:
•Freeze protection down to -36° C (-34° F).
•Boiling protection up to 129° C (265° F).
•Protection against rust and other forms of corrosion.
•Enables calibrated gauges to work properly.

•Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
•Resting your foot on the brake pedal while driving may reduce fuel
economy.
•Combine errands and minimize stop-and-go driving.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toLubricant specificationsin
this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle scheduled maintenance guide.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•Using fuel blended with alcohol may lower fuel economy.
•Fuel economy may decrease with lower temperatures during the first
12–16 km (8–10 miles) of driving.
•Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
•Close windows for high speed driving.
EPA window sticker
Every new vehicle should have the EPA window sticker. Contact your
dealer if the window sticker is not supplied with your vehicle. The EPA
window sticker should be your guide for the fuel economy comparisons
with other vehicles.
