2008 Mercury Mariner Hybrid maintenance mode

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

WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause extensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulbs work. If any light remains on after starting the vehicle, refer to the
respective system warning light for additional information.
Check engine:TheCheck Engine
indicator light illuminates when the
ignition is first turned to the RUN
position to check the bulb and to
indicate whether the vehicle is ready for Inspection/Maintenance (I/M)
testing. Normally, the
Check Engine
light will stay on until the engine is
cranked, then turn itself off if no malfunctions are present. However, if
after 15 seconds the
Check Engine
light blinks eight times, it means
that the vehicle is not ready for I/M testing. See theReadiness for
Inspection/Maintenance (I/M) testingin theMaintenance and
Specificationschapter.
Solid illumination after the engine is started indicates the On Board
Diagnostics System (OBD-II) has detected a malfunction. Refer toOn
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 by your authorized dealer.

Odometer:Registers the total miles
(kilometers) of the vehicle.
Refer toMessage Centerin the
Driver Controlschapter on how to
switch the display from Metric to
English.
Trip odometer:Registers the miles
(kilometers) of individual journeys.
To reset, press and release the
message center INFO button until
TRIP A mode appears in the display.
Press the control again to select the
TRIP B feature. Press and hold the RESET button to reset.
Tachometer:Indicates the engine
speed in revolutions per minute.
Driving with your tachometer
pointer continuously at the top of
the scale (in the red zone) may
damage the engine. The pointer will
indicate engine RPMs when the
engine is running and point at the
EV symbol when the engine is off and the vehicle is running on pure
electrical power.
Fuel gauge:Indicates
approximately how much fuel is left
in the fuel tank (when the ignition
is in the ON position). The fuel
gauge may vary slightly when the
vehicle is in motion or on a grade.
Refer toFilling the tankin the
Maintenance and Specifications
chapter for more information.

2. Each time you fill the tank, record the amount of fuel added (in
gallons or liters).
3. After at least three to five tank fill-ups, fill the fuel tank and record
the current odometer reading.
4. Subtract your initial odometer reading from the current odometer
reading.
5. Follow one of the simple calculations in order to determine fuel
economy:
Calculation 1:Divide total miles traveled by total gallons used.
Calculation 2:Multiply liters used by 100, then divide by total
kilometers traveled.
Keep a record for at least one month and record the type of driving (city
or highway). This will provide an accurate estimate of the vehicle’s fuel
economy under current driving conditions. Additionally, keeping records
during summer and winter will show how temperature impacts fuel
economy. In general, very hot or very cold temperatures give lower fuel
economy.
Driving style — good driving and fuel economy habits
Since it is able to operate in electric mode and to collect braking energy,
your hybrid vehicle will get better fuel economy in city driving than on
the highway. This is contrary to conventional vehicles. However, many of
the same actions that improve fuel economy in a conventional vehicle
will also improve fuel economy in this vehicle.
Give consideration to the lists that follow and you may be able to
improve your fuel economy.
Habits
•Avoid aggressive driving. Quick acceleration and deceleration decrease
fuel economy.
•Drive at a smooth, constant speed. Excessive variation in pedal input
causes more operating mode changes and reduces efficiency.
•Drive at reasonable speeds. Traveling at 60 mph [96 km/h] uses
approximately 20% less fuel than traveling at 70 mph [112 km/h]).
•Minimize A/C and defroster usage. Selecting defrost, or defrost/floor
mode on the climate control system will force the engine to run
continuously, which reduces fuel economy. Selecting AUTO will
typically force the engine to run continuously, unless ECON is
selected.

•Minimize temperature extremes when the vehicle is parked, for
example by storing in a garage to avoid extreme cold in winter and
extreme sun loads in summer. The high voltage battery operates more
efficiently in moderate temperatures.
•Combine errands. Your vehicle is more fuel efficient when the engine
is warm. Driving to your farthest destination first will warm the engine
more quickly and may improve fuel economy for the rest of the trip.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Keep wheels properly aligned.
•Use recommended engine oil. Refer toLubricant specificationsin
this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found inscheduled maintenance information.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
1 mpg [0.4 km/L] is lost for every 300 lb [136 kg] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks, flags)
may reduce fuel economy.
•Using fuel blended with alcohol may lower fuel economy.
•Driving on flat terrain offers improved fuel economy as compared to
driving on mountainous terrain.
•Close windows for high speed driving.
EPA window sticker
Every new vehicle should have the EPA window sticker. Contact your
authorized dealer if the window sticker is not supplied with your vehicle.
The EPA window sticker should be your guide for the fuel economy
comparisons with other vehicles.
It is important to note the box in the lower left corner of the window
sticker. These numbers represent the Range of MPG (L/100 km)
expected on the vehicle under optimum conditions. Your fuel economy
may vary depending upon the method of operation and conditions.

BRAKE FLUID
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
Check fluid levels with the ignition
in the RUN position. Fluid levels
between the “MIN” and “MAX” lines
are within the normal operating
range; there is no need to add fluid.
If the fluid levels are outside of the
normal operating range the
performance of your brake system could be compromised; seek service
from your authorized dealer immediately.
Brake pad replacement information
The Regenerative Braking System checks the integrity of the brake
system at times when the vehicle is parked. This is done by developing
brake pressure for short periods of time. In order to change the brake
pads, it is necessary to enter the Pad Service Mode. This will prevent
brake pressure from being applied.
To enter the Pad Service Mode, perform the following with the vehicle
stationary:
1. Place the vehicle in Park and turn ignition to the ON position.
2. Apply the brake pedal.
3. Turn the ignition OFF, then ON three times and then release the brake
pedal. The total time elapsed for the three ignition cycles and brake
release must beless than 3 seconds.
The brake warning lamp will:
•flash as stored hydraulic pressure is released.
•remain illuminated once the pressure is completely released.
•flash if the brake is applied.
To exit the Pad Service Mode:
1. Apply the brake pedal and turn the ignition OFF then ON. This will
cause brake pressure to be developed within the brake system. Once
brake pressure is developed, the brake warning light will turn off.
2. The Pad Service Mode will also be exited if the gear shift lever is
moved from the (P) Park position, the vehicle is moved (wheels rotate)
or the ignition is turned OFF.
