2008 Mercury Mariner Hybrid Owner's Manuals

The “ECON” mode turns itself off when you select defrost or
defrost/floor mode, although on cold days, you may still experience
engine shut-down while in defrost or defrost/floor mode.
Drive Habits:Aggressive driving increases the amount of energy
required to move your vehicle. In general, better fuel economy is
achieved with mild to moderate acceleration and deceleration. Moderate
braking is particularly important since it allows you to maximize the
energy captured by the regenerative braking system.
NOTE:Having your engine running is not always an indication of
inefficiency – in some cases it is actually more efficient than driving in
electric mode.
Additional Tips:
•Do not carry extra loads
•Be mindful of adding external accessories that may increase
aerodynamic drag
•Observe posted speed limits
•Perform all scheduled maintenance
•There is no need to wait for your engine to “warm up”. The vehicle is
ready to drive immediately after starting

Frequently asked questions
Question Answer
What is the pumping sound I hear
when I unlock or enter the vehicle,
and the venting sound a few
minutes after shutting off my
vehicle?This is the hydraulic portion of
your regenerative braking system
pressurizing and depressurizing.
You may also hear it occasionally
after pressing the brake pedal.
What are the series of clicks from
the cargo area when I first turn
the key in the ignition?The high voltage battery is
electrically isolated from the rest
of the vehicle when the key is
OFF. When the key is turned ON,
high voltage contactors inside the
battery are closed to make the
electricity available to the
motor/generator and enable the
vehicle to drive. The clicks are the
sound of these contactors as they
close and open during start up and
shut down.
Why does the engine always start
at key-on?Your engine is started at key-on
because the emission components
need to be warm in order to
minimize tailpipe emissions, and in
cooler climates for cabin heating
and windshield defrost
performance.
After I start my car in the
morning, why does it take a long
time before the engine shuts
down?There are several reasons the
engine stays on for an extended
amount of time when it is first
started. One common reason is to
ensure that the emissions
components are warm enough to
minimize tailpipe emissions. As the
climate gets cooler, this
“engine-ON” time is extended.

Question Answer
Why does my engine never shut
down above 40 mph (64 km/h)?The engine is required to turn on
above this speed to protect the
transaxle hardware.
Why does my engine stay ON
when it’s extremely cold outside?In order to ensure that the climate
control system can begin heating
the cabin and/or defrosting the
windshield as soon as a driver
requests it, the engine coolant
temperature has to be kept
sufficiently hot. Keeping the
engine on is required to maintain
the correct minimum temperature.
Why does my engine rev up so
high sometimes when I accelerate?Your vehicle’s engine and
transmission are designed to
deliver the power you need at the
most efficient engine speed. This
may be higher than expected
during heavy accelerations, and
may fluctuate during steady state
driving. These are characteristics
of the Atkinson engine cycle and
the eCVT transaxle technology
that help maximize your hybrid’s
fuel economy.
What does it mean when my
power assist gauge moves to the
right? To the left?Electricity is coming out of the
battery when the gauge moves to
the right. Electricity is going into
the battery when the gauge moves
to the left.

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.
