HAZARD WARNING FLASHERSThe hazard flasher control is located on the instrument panel
by the radio. Use it when your vehicle is disabled and is
creating a safety hazard for other motorists.
•
Press the flasher control and all front and rear direction signals will flash.
• Press the flasher control again to turn them off.
Note:
With extended use, the flashers may run down your 12–volt battery.
FUEL SHUTOFF
WARNING: Failure to inspect and, if necessary, repair fuel leaks
after a collision may increase the risk of fire and serious injury.
Ford Motor Company recommends that the fuel system be inspected by
an authorized dealer after any collision.
In the event of a moderate to severe collision, this vehicle includes a fuel
pump shut-off feature that stops the flow of fuel to the engine. Not every
impact will cause a shut off.
Should your vehicle shut off after a collision, you may restart your
vehicle by doing the following:
1. Switch off the ignition.
2. Switch on the ignition.
3. Repeat Steps 1 and 2 to re-enable the fuel pump.
For vehicles equipped with a push button start system:
1. Press the START/STOP button to switch off the ignition.
2. Press the brake pedal and press the START/STOP button to start the
vehicle.
3. Remove your foot from the brake pedal and press the START/STOP
button to switch off the ignition.
4. You can either attempt to start the engine by pressing the brake pedal
and the START/STOP button, or switch on the ignition only by pressing
the START/STOP button without pressing the brake pedal. Both ways
re-enable the fuel system.
Note: When you try to restart your vehicle after a fuel shutoff, the
vehicle makes sure that various systems are safe to restart. Once your
vehicle determines that the systems are safe, then the vehicle will allow
you to restart.
Note: In the event that your vehicle does not restart after your third
attempt, contact an authorized dealer.

JUMP-STARTING THE VEHICLE
WARNING:The gases around the battery can explode if exposed
to flames, sparks, or lit cigarettes. An explosion could result in
injury or vehicle damage.
WARNING: Batteries contain sulfuric acid which can burn skin,
eyes and clothing, if contacted.
Do not attempt to push-start your automatic transmission vehicle.
Automatic transmissions do not have push-start capability. Attempting to
push-start a vehicle with an automatic transmission may cause
transmission damage.
When the battery is disconnected or a new battery is installed, the
automatic transmission must relearn its shift strategy. As a result, the
transmission may exhibit a combination of firm and 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.
Preparing Your Vehicle
Note: Use only a 12–volt supply to start your vehicle.
Note: Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.
1. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehicles do not touch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
2. Check all battery terminals. Remove the positive terminal cover (if
equipped) and any excessive corrosion before you attach the battery
cables. Ensure that vent caps are tight and level.
3. Turn the heater fan on in both vehicles to protect from any electrical
surges. Turn all other accessories off.

ENGINE OIL CHECK
Refer to the scheduled maintenance information 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 15 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.
5. Locate and carefully remove the engine oil level dipstick. See the
Under Hood Overview in this chapter for location of dipstick.
6. Wipe the dipstick clean. Insert the dipstick fully, then remove it again.
If the oil level is between the lower and upper holes or between the MIN
and MAX marks (depending on application), the oil level is acceptable.
DO NOT ADD OIL.
If the oil level is below the lower hole or the MIN mark, add enough oil
to raise the level within the lower and upper holes or within the
MIN-MAX range.
Oil levels above the upper hole or the MAX mark may cause engine
damage. Some oil must be removed from the engine by an authorized
dealer.
7. Put the dipstick back in and ensure it is fully seated.
Adding Engine Oil
Note: Do not remove the engine oil level dipstick or the filler cap when
the engine is running.
