2008 Mercury Mariner Hybrid engine

Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, services,
sells, leases, trades vehicles, or supervises a fleet of vehicles are not
permitted to intentionally remove an emission control device or prevent
it from working. Information about your vehicle’s emission system is on
the Vehicle Emission Control Information Decal located on or near the
engine. This decal identifies engine displacement and gives some tune up
specifications.
Please consult yourWarranty Guidefor complete emission warranty
information.
On board diagnostics (OBD-II)
Your vehicle is equipped with a computer that monitors the engine’s
emission control system. This system is commonly known as the On
Board Diagnostics System (OBD-II). The OBD-II system protects the
environment by ensuring that your vehicle continues to meet
government emission standards. The OBD-II system also assists your
authorized dealer in properly servicing your vehicle. When the
indicator illuminates, the OBD-II system has detected a malfunction.
Temporary malfunctions may cause the
indicator to illuminate.
Examples are:
1. The vehicle has run out of fuel—the engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel—the engine may misfire or run
poorly.
3. The fuel cap may not have been securely tightened. SeeFuel filler
capin this chapter.
4. Driving through deep water—the electrical system may be wet.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel, properly tightening the fuel cap or letting the
electrical system dry out. After three driving cycles without these or any
other temporary malfunctions present, the
indicator should stay off
the next time the engine is started. A driving cycle consists of a cold
engine startup followed by mixed city/highway driving. No additional
vehicle service is required.
If the
indicator remains on, have your vehicle serviced at the first
available opportunity. Although some malfunctions detected by the
OBD-II may not have symptoms that are apparent, continued driving
with the
indicator on can result in increased emissions, lower fuel
economy, reduced engine and transmission smoothness, and lead to more
costly repairs.

Readiness for Inspection/Maintenance (I/M) testing
Some state/provincial and local governments may have
Inspection/Maintenance (I/M) programs to inspect the emission control
equipment on your vehicle. Failure to pass this inspection could prevent
you from getting a vehicle registration. Your vehicle may not pass the I/M
test if the
indicator is on or not working properly (bulb is burned
out), or if the OBD-II system has determined that some of the emission
control systems have not been properly checked. In this case, the vehicle
is considered not ready for I/M testing.
If the
indicator is on or the bulb does not work, the vehicle may
need to be serviced. Refer to the On board diagnostics (OBD-II)
description in this chapter.
If the vehicle’s engine or transmission has just been serviced, or the
battery has recently run down or been replaced, the OBD-II system may
indicate that the vehicle is not ready for I/M testing. To determine if the
vehicle is ready for I/M testing, turn the ignition key to the ON position
for 15 seconds without cranking the engine. If the
indicator blinks
eight times, it means that the vehicle is not ready for I/M testing; if
the
indicator stays on solid, it means that the vehicle is ready for
I/M testing.
The OBD-II system is designed to check the emission control system
during normal driving. A complete check may take several days. If the
vehicle is not ready for I/M testing, the following driving cycle consisting
of mixed city and highway driving may be performed:
15 minutes of steady driving on an expressway/highway followed by 20
minutes of stop-and-go driving with at least four 30-second idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete. If
the vehicle is still not ready for I/M testing, the above driving cycle will
have to be repeated.

TRANSMISSION FLUID
Checking electronically controlled continuously variable
transmission (eCVT)
Refer to yourscheduled maintenance informationchapter for
scheduled intervals for fluid checks and changes. Your transaxle does not
consume fluid. It is designed to be filled for life. However, the fluid level
should be checked if you notice some sign of fluid leakage.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is warmed up
(approximately 20 miles [30 km]). If your vehicle has been
operated for an extended period at high speeds, in city traffic
during hot weather or pulling a trailer, the vehicle should be
turned off for about 30 minutes to allow fluid to cool before
checking.
1. Drive the vehicle 20 miles (30 km) or until it reaches normal operating
temperature.
2. Park the vehicle on a level surface and engage the parking brake.
3. With the parking brake engaged
and your foot on the brake pedal,
turn the key to the ACCESSORY
position but do not start the engine.
Turn the wheel to the left to gain
access to the check plug.
4. Latch the gearshift lever in P (Park) and make sure that the engine is
OFF by placing the ignition in the Lock position.

5. Using the hole in the splash
shield, remove the check plug from
the side of the transmission.
If this is the first check of the
transmission fluid, it may be
necessary to remove the perforated
section of the splash shield (as
indicated on the splash shield).
6. Be sure the engine has been stopped for at least 3 minutes before
performing the fluid level check.

7. The fluid level should be within
1/4 inch (6 mm) of the plug threads.
8. Replace the check plug.
Adjusting eCVT fluid levels
Before adding any fluid, make sure the correct type is used. The type of
fluid used is indicated in theMaintenance product specifications and
capacitiessection in this chapter.
Use of a non-approved fluid may cause internal transaxle
component damage.
If the fluid level is low, add fluid through the check port until the level is
correct and fluid begins to run out of the transmission. If an overfill
occurs, excess fluid should be removed by allowing the fluid to run out
of the check port.
A serious overfill condition of transmission fluid may cause
damage.
Do not use supplemental transmission fluid additives, treatments or
cleaning agents. The use of these materials may affect transmission
operation and result in damage to internal transmission components.
AIR FILTER
Refer toscheduled maintenance informationfor the appropriate
intervals for changing the air filter element.
When changing the air filter element, use only the Motorcraft air filter
element listed. Refer toMotorcraft part numbersin this chapter.
To reduce the risk of vehicle damage and/or personal burn
injuries do not start your engine with the air cleaner removed
and do not remove it while the engine is running.
