2007 Mercury Mariner Hybrid cooling

Stopping the vehicle
•The vehicle’s engine may shut off as you come to a stop; this is a
normal condition and helps to conserve fuel. You do not need to
restart the vehicle.
Neutral operation
•The vehicle does not charge the high voltage battery in the N
(Neutral) position. Do not idle the vehicle in N (Neutral) for extended
periods as this will discharge the high voltage battery.
Low gear operation
•In L (Low) gear, you may feel an increased sensation of engine
braking as you remove your foot from the accelerator. L (Low) gear
can be helpful when driving down an incline; unlike in a conventional
vehicle, L (Low) does not offer an advantage over D (Drive) in uphill
or off-road driving conditions.
Reverse operation
•Vehicle speed is limited to 22 mph (35 km/h) while operating in R
(Reverse) gear.
MARINER HYBRID UNIQUE OPERATING CHARACTERISTICS
•You may hear some unique sounds from a hybrid vehicle. The Mariner
Hybrid is equipped with a high voltage battery air conditioning system
in the rear of the vehicle which cools the high voltage battery in order
to ensure high voltage battery life and optimize performance. You may
hear a slight clunk or tap noise as the vent door operates, as well as a
fan noise in the rear of the vehicle; this noise is the high voltage
battery cooling fan. The high voltage battery cooling may also continue
to operate for short durations after the vehicle has been turned off.
These vehicle conditions and noises are normal and do not require
service.
•You may hear a pumping sound when you enter the vehicle or a
venting sound a few minutes after parking the vehicle. This is due to
charging and discharging of the hydraulic portion of the regenerative
braking system.
•You may hear a slight whine or whistle when operating your vehicle.
This noise could occur at idle, and during cruising and accelerating; it
is caused by the normal operation of electrical generator in the hybrid
system.

1.Use only a 12–volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect any electrical
surges. Turn all other accessories off.
Connecting the jumper cables
1. Connect the positive (+) jumper cable to the positive (+) terminal of
the discharged battery.
Note:In the illustrations,lightning boltsare used to designate the
assisting (boosting) battery.

WINDSHIELD WASHER FLUID
Add fluid to fill the reservoir if the
level is low. In very cold weather, do
not fill the reservoir completely.
Only use a washer fluid that meets Ford specifications. Do not use any
special washer fluid such as windshield water repellent type fluid or bug
wash. They may cause squeaking, chatter noise, streaking and smearing.
Refer to theMaintenance product specifications and capacities
section in this chapter.
State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle’s paint finish, wiper blades or washer system.
If you operate your vehicle in temperatures below 40° F (4.5°C),
use washer fluid with antifreeze protection. Failure to use
washer fluid with antifreeze protection in cold weather could result in
impaired windshield vision and increase the risk of injury or accident.
Note:Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling system
components.
Checking and adding washer fluid for the liftgate
Washer fluid for the liftgate is supplied by the same reservoir as the
windshield.

•Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized
standards for disposal. Call your
local authorized recycling center
to find out more about recycling
automotive batteries.
Low and high voltage battery – storage
Your vehicle must be started and run for a minimum of 10 minutes once
a month in order to maintain the high voltage battery charge. This will
maintain the high voltage battery but it is not enough to maintain the
low voltage (underhood) battery and additional low voltage (underhood)
battery charging may be required after 60 days.
If your vehicle is to be stored for 30 days or longer, the low voltage
(underhood) battery negative terminal must be disconnected. Failure to
do this could damage your vehicle’s batteries.
ENGINE COOLANT AND MOTOR/ELECTRONICS COOLANT
Your vehicle is equipped with two separate coolant systems. One is for
engine cooling and the other is for various electric motors and other
components that are specific to the hybrid operating systems.

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.
