2010 Mercury Mariner fuse

Note:With extended use, the flasher may run down your battery.
FUEL PUMP SHUT-OFF SWITCH
This device stops the electric fuel pump from sending fuel to the engine
when your vehicle has had a substantial jolt.
After an accident, if the engine cranks but does not start, this switch
may have been activated.
This switch is located in the front
passenger’s footwell, behind a
flip-up cover, by the kick panel
access cover.
To reset the switch:
1. Turn the ignition to the off
position.
2. Check the fuel system for leaks.
3. If no leaks are apparent, reset the
switch by pushing in on the reset
button.
4. Turn the ignition to the on
position.
5. Wait a few seconds and return
the key to the off position.
6. Make another check for leaks.
FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Note:Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.

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). This temporary spare tire is
not equipped with a tire pressure monitor system (TPMS) sensor.
Note:The tire pressure monitoring system (TPMS) indicator light will
illuminate when the spare is in use. To restore the full functionality of
the TPMS system, all road wheels equipped with the tire pressure
monitoring sensors must be mounted on the vehicle.
Have a flat tire serviced by an authorized dealer in order to prevent
damage to the TPMS sensor, refer toTire pressure monitoring system
(TPMS)in theTires, Wheels, and Loadingchapter. Replace the spare
tire with a road tire as soon as possible. During repairing or replacing of
the flat tire, have the authorized dealer inspect the TPMS sensor for
damage.
