2009 Mercury Mariner Hybrid oil temperature

Do not add friction modifier compounds or special break-in oils since
these additives may prevent piston ring seating. SeeEngine oilin the
Maintenance and Specificationschapter for more information on oil
usage.
HYBRID OPERATION
The Hybrid is a whole new kind of SUV that combines electric and
gasoline propulsion without compromise, to provide breakthrough
performance and efficiency. It requires no special fuels and never has to
be plugged in. Familiarizing yourself with these unique characteristics
will help ensure optimal performance from your new vehicle.
Normal vehicle operation
Starting:Turn the ignition key to the START position while your vehicle
is in Park (P). The gas engine will turn on,accompanied by the green
“ready indicator” light. Your engine may shut off shortly after starting,
depending on temperature and battery charge level. This is a natural
part of your Hybrid’s fuel-saving features. The “ready indicator” light will
stay on, and you do not need to restart the vehicle.
Note:You may notice higher engine speeds upon start-up. This
temporary condition is normal and necessary to heat up the cabin for
occupant comfort.
Driving:The gas engine automatically starts and stops to provide power
when it’s needed and to save fuel when it’s not. While coasting at low
speeds, coming to a stop, or standing, the gas engine normally shuts
down and the vehicle operates in electric-only mode. Conditions that
may cause the engine to start up or remain running include:
•Driving request for moderate to rapid acceleration
•Vehicle speed above 40 mph (65 kph)
•Ascending a hill
•ECON mode not selected (while Climate Control is ON)
•Selection of climate control defrost mode or defrost/floor mode
•Charge level of high voltage battery is low
•Very high or low outside temperature (to provide system
cooling/heating)
Stopping:The gas engine may shut off to conserve fuel as you come to
a stop. Restarting the vehicle is not required. Simply step on the
accelerator when you are ready to drive.

Ready indicator light:Illuminates
once the vehicle has successfully
started. Indicates the vehicle is
ready to drive even when you don’t
hear the engine running.
Charging system:Illuminates when
the 12V charging system is not
working properly.
Engine oil pressure:Illuminates
when the oil pressure falls below the
normal range, refer toEngine oilin
theMaintenance and
Specificationschapter.
Engine or motor electronic
coolant temperature:Illuminates
when the coolant temperature
exceeds the threshold. When the light is flashing or remains on, stop the
vehicle as soon as possible, switch off the engine and let cool. Refer to

INSTRUMENT PANEL/INTERIOR TRIM AND CLUSTER LENS
Clean the instrument panel, interior trim areas and cluster lens with a
clean and damp white cotton cloth, then with a clean and dry white
cotton cloth; you may also use Motorcraft Dash & Vinyl Cleaner
(ZC-38-A) on the instrument panel and interior trim areas.
•Avoid cleaners or polishes that increase the gloss of the upper portion
of the instrument panel. The dull finish in this area helps protect the
driver from undesirable windshield reflection.
•Be certain to wash or wipe your hands clean if you have been in
contact with certain products such as insect repellent and suntan
lotion in order to avoid possible damage to the interior painted
surfaces.
•Do not use household or glass cleaners as these may damage the
finish of the instrument panel, interior trim and cluster lens.
WARNING:Do not use chemical solvents or strong detergents
when cleaning the steering wheel or instrument panel to avoid
contamination of the airbag system.
If a staining liquid like coffee/juice has been spilled on the instrument
panel or on interior trim surfaces, clean as follows:
1. Wipe up spilled liquid using a clean, white, cotton cloth.
2. Apply Motorcraft Deluxe Leather and Vinyl Cleaner (ZC-11-A) [In
Canada use Motorcraft Multi-Purpose Cleaner (CXC-101)] to the wiped
area and spread around evenly.
3. Apply more Motorcraft cleaner to a clean, white, cotton cloth and
press the cloth onto the soiled area–allow this to set at room
temperature for 30 minutes.
4. Remove the soaked cloth, and if it is not soiled badly, use this cloth to
clean the area by using a rubbing motion for 60 seconds.
5. Following this, wipe area dry with a clean, white, cotton cloth.
INTERIOR
For fabric, carpets, cloth seats, safety belts and seats equipped with side
airbags:
•Remove dust and loose dirt with a vacuum cleaner.
•Remove light stains and soil with Motorcraft Professional Strength
Carpet & Upholstery Cleaner (ZC-54).

Checking motor/electronics (M/E) coolant
The M/E coolant reservoir is located
behind the engine coolant reservoir.
Refer to the following engine
coolant sections for all information,
instructions and warnings related to
cooling systems. The two systems
use the same coolant and operate
similarly, with the Motor and
Electronics system generally
operating at a lower temperature
and pressure. The fluid levels in
both reservoirs need to be
maintained. When the engine is
cold, check the level of M/E coolant
in the reservoir.
Factory fill and coolant specifications
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50–50 mixture of coolant and water provides the following:
•Freeze protection down to -34°F (-36°C).
•Boiling protection up to 265°F (129°C).
•Protection against rust and other forms of corrosion.
•Enables calibrated gauges to work properly.
Common instructions for cooling systems
•The engine coolant should be at the “FULL COLD” level or within the
“COLD FILL RANGE” as listed on the engine coolant reservoir
(depending upon application).
•Refer to thescheduled maintenance informationfor service interval
schedules.
•Be sure to read and understandPrecautions when servicing your
vehiclein this chapter.

Maintenance and Specifications
282

•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. ECON will allow the engine to shut down for a period of
time, even when air conditioning is requested.
•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.
