2005 FORD EXPLORER check engine light

Service engine soon:TheService
engine soonindicator light
illuminates when the ignition is first
turned to the ON position to check
the bulb. Solid illumination after the engine is started indicates the On
Board Diagnostics System (OBD-II) has detected a malfunction. Refer to
On board diagnostics (OBD-II)in theMaintenance and Specifications
chapter. If the light is blinking, engine misfire is occurring which could
damage your catalytic converter. Drive in a moderate fashion (avoid
heavy acceleration and deceleration) and have your vehicle serviced
immediately.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.
Check fuel cap (if equipped):
Illuminates when the fuel cap may
not be properly installed. Continued
driving with this light on may cause
the Service engine soon light to
come on, refer toFuel filler capin theMaintenance and
Specificationschapter.
Brake system warning light:To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the ON position when the engine is not running, or
in a position between ON and START, or by applying the parking brake
when the ignition is turned to the ON position. If the brake system
warning light does not illuminate at this time, seek service immediately
from your dealership. Illumination after releasing the parking brake
indicates low brake fluid level and the brake system should be inspected
immediately by your servicing dealership.
Driving a vehicle with the brake system warning light on is
dangerous. A significant decrease in braking performance may
occur. It will take you longer to stop the vehicle. Have the vehicle
checked by your dealer immediately.

STARTING
Positions of the ignition
1. OFF/LOCK, shuts off the engine
and all accessories/locks the steering
wheel, gearshift lever and allows key
removal.
2. ACC, allows the electrical
accessories such as the radio to
operate while the engine is not
running. This position also unlocks
the steering wheel.
3. ON, all electrical circuits
operational. Warning lights illuminated. Key position when driving.
4. START, cranks the engine. Release the key as soon as the engine
starts.

If a failure is detected in the AdvanceTrac
/Roll Stability Control
system, the warning indicator light in the instrument cluster will stay on.
If the warning indicator light in the instrument cluster remains on while
the engine is running, have the system serviced immediately.
Pressing the control once will disable the AdvanceTrac
stability
enhancement/Roll Stability Control and the engine power reduction
portion of the traction enhancement feature; the brake portion of the
traction enhancement feature will still function normally. Pressing and
holding the control for more than five seconds will disable the
AdvanceTrac
stability enhancement/Roll Stability Control and traction
enhancement feature. If the vehicle is stuck in snow or mud or when
driving in deep sand, switching off the AdvanceTrac
system may be
beneficial so the wheels are allowed to spin. If your vehicle seems to lose
engine power while driving in deep sand or very deep snow, switching off
the AdvanceTrac
stability enhancement feature will restore full engine
power and will enhance momentum through the obstacle.
Some drivers may notice a slight movement of the brake pedal when the
AdvanceTrac
performs a system self-check. During AdvanceTrac
/Roll
Stability Control operation you may experience the following:
•A rumble or grinding noise
•A slight deceleration of the vehicle
•The AdvanceTrac
indicator light will flash
•If your foot is on the brake pedal, you will feel a vibration in the
pedal.
•If the driving condition is severe and your foot is not on the brake, the
brake pedal will move to apply higher brake forces. You may also hear
a whoosh of air from under the instrument panel during this severe
condition.
All these conditions are normal during AdvanceTrac
/Roll Stability
Control operation.
Do not alter or modify your vehicle’s suspension or steering; the
resulting changes to the vehicle’s handling can adversely affect
the AdvanceTrac
/Roll Stability Control system. Also, do not
install a stereo loudspeaker near the rear console or either rear
seat. The speaker vibrations can adversely affect the
AdvanceTrac
/Roll Stability Control sensors located in this area.
Note:Pressing the AdvanceTrac
button will disable AdvanceTrac
and
Roll Stability Control.

when you are driving over sand, apply the accelerator slowly and avoid
spinning your wheels. If the vehicle does slide, steer in the direction of
the slide until you regain control of the vehicle.
If the transmission, transfer case or front axle are submerged in water,
their fluids should be checked and changed, if necessary.
Driving through deep water may damage the transmission.
If the front or rear axle is submerged in water, the axle lubricant should
be replaced.
After driving through mud, clean off residue stuck to rotating driveshafts
and tires. Excess mud stuck on tires and rotating driveshafts causes an
imbalance that could damage drive components.
“Tread Lightly” is an educational
program designed to increase public
awareness of land-use regulations
and responsibilities in our nations
wilderness areas. Ford Motor
Company joins the U.S. Forest Service and the Bureau of Land
Management in encouraging you to help preserve our national forest and
other public and private lands by “treading lightly.”
Driving on hilly or sloping terrain
Although natural obstacles may make it necessary to travel diagonally up
or down a hill or steep incline, you should always try to drive straight up
or straight down.Avoid driving crosswise or turning on steep
slopes or hills.A danger lies in losing traction, slipping sideways and
possibly rolling over. Whenever driving on a hill, determine beforehand
the route you will use. Do not drive over the crest of a hill without
seeing what conditions are on the other side. Do not drive in reverse
over a hill without the aid of an observer.
When climbing a steep slope or hill,
start in a lower gear rather than
downshifting to a lower gear from a
higher gear once the ascent has
started. This reduces strain on the
engine and the possibility of stalling.
If you do stall out, Do not try to
turnaround because you might roll
over. It is better to back down to a
safe location.

Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
transmission must relearn its shift strategy. As a result, the transmission
may have firm and/or soft shifts. This operation is considered normal and
will not affect function or durability of the transmission. Over time, the
adaptive learning process will fully update transmission operation.
1.Use only a 12–volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect any electrical
surges. Turn all other accessories off.
Connecting the jumper cables
1. Connect the positive (+) jumper cable to the positive (+) terminal of
the discharged battery.
