2008 Mercury Mariner Hybrid fuel

Question Answer
What is the fan noise and slight
tapping sound I hear from the rear
of my hybrid?The fan noise comes from two fans
located inside the high voltage
battery. These fans turn on when
the battery requires cooling air.
The fan speed, and associated
noise level, will change according
to the amount of cooling required
to maintain good performance.
How far can I go in Electric Drive
if I run out of gas?Running out of gas is not
recommended. However, you may
be able to go about one mile,
driving at 30 mph (48 km/h), if the
battery has a normal state of
charge.
What is the engine oil change
service interval?The engine oil should be changed
every 10,000 miles (16,000 km)
under normal operating conditions.
See theScheduled maintenance
guidechapter.
Can I put E10 or E85 in my
vehicle, and how will it affect my
fuel economy?Your hybrid vehicle can use E10
(10% ethanol, 90% gasoline) fuel,
but you may notice slightly
reduced fuel economy because
ethanol contains less energy per
gallon than gasoline. Your hybrid
vehicle is not designed to use E85
(85% ethanol).
How long will my high voltage
battery last? Does it need
maintenance?The high voltage battery system is
designed to last the life of the
vehicle and requires no
maintenance.

Question Answer
Can you charge the battery with a
plug into an A/C outlet?There are no provisions for
charging the high voltage battery
from a power supply external to
the vehicle.
What is the purpose of the ECON
button?ECON mode may provide
improved fuel economy by
preventing the gasoline engine
from running for the sole purpose
of providing air conditioning. When
the engine turns off, the A/C
compressor does not operate and
warm air may come out of the
vents. In ECON mode, A/C
operates as normal when the
gasoline engine is running.
Can I tow the hybrid behind my
motor home with all four wheels
down?Yes. Your hybrid vehicle can be
“flat-towed” without modification.
See theRecreational Towing
section in theTires, Wheels and
Loadingchapter for more
information.

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:Illuminates when
the fuel cap may not be properly
installed. Continued driving with
this light on may cause the Check
engine warning light to come on,
refer toFuel filler capin the
Maintenance and Specificationchapter.
Brake system warning light:To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the RUN
position (when the engine is not running), or in a position between RUN
and START, or by applying the parking brake when the ignition is turned
to the RUN position. If the brake system warning light does not
illuminate at this time, seek service immediately from your authorized
dealer. Illumination after releasing the parking brake indicates low brake
fluid level and the brake system should be inspected immediately by
your authorized dealer.
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 authorized dealer. Driving extended distances with
the parking brake engaged can cause brake failure and the risk of
personal injury.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately by your
authorized dealer. Normal braking is still functional unless the brake
warning light also is illuminated.

Note: If the vehicle is still running, the vehicle may soon
shutdown without further warning and should be stopped safely.
If this lamp is lit, stop the vehicle, shift to P (Park), turn the key to the
Off position, and attempt to restart the vehicle. If the fault remains, the
vehicle may require refueling, jump starting, resetting of the shut-off
switches, or service. For information regardingLow voltage
[underhood] battery only)andFuel pump/High voltage shut-off

start up or while driving, the tire
pressure should be checked. Refer
toInspecting and Inflating Your Tiresin theTires, Wheels and
Loadingchapter. When the ignition is first turned to RUN, the light will
illuminate for 3 seconds to ensure the bulb is working. If the light does
not turn ON or begins to flash, have the system inspected by your
authorized dealer. For more information on this system, refer to
Understanding Your Tire Pressure Monitoring Systemin theTires,
Wheels and Loadingchapter.
