2008 Mercury Mariner Hybrid check transmission fluid

Avoid excessive speed because vehicle momentum can work against you
and cause the vehicle to become stuck to the point that assistance may
be required from another vehicle. Remember, you may be able to back
out the way you came if you proceed with caution.
Mud and water
If you must drive through high
water, drive slowly. Traction or
brake capability may be limited.
When driving through water,
determine the depth; avoid water
higher than the bottom of the hubs
(if possible) and proceed slowly. If
the ignition system gets wet, the vehicle may stall.
Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes. Drying can be improved by moving
your vehicle slowly while applying light pressure on the brake pedal.
Be cautious of sudden changes in vehicle speed or direction when you
are driving in mud. Even 4WD vehicles can lose traction in slick mud. As
when you are driving over sand, apply the accelerator slowly and avoid
spinning your wheels. If the vehicle does slide, steer in the direction of
the slide until you regain control of the vehicle.
If the transmission, transfer case or front axle are submerged in water,
their fluids should be checked and changed, if necessary.
Driving through deep water may damage the transmission.
If the front or rear axle is submerged in water, the axle lubricant should
be replaced.
After driving through mud, clean off residue stuck to rotating driveshafts
and tires. Excess mud stuck on tires and rotating driveshafts causes an
imbalance that could damage drive components.

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.

requirements of Ford specification WSS-M2C930-A and the API Certification mark.3Indicates only approximate dry-fill capacity.4Using any transmission fluid other than those that meet the recommended specification may cause
internal transaxle damage. Do not use Motorcraft MERCONCVT (blue) ATF. This vehicle uses
only Motorcraft MERCONVATF5Fill to 1/4 inch to 9/16 inch (6 mm to 14 mm) below bottom of fill hole.64WD vehicles exposed for prolonged periods to temperatures less than -40° C (-40° F) should
change out the rear axle fluid to Motorcraft SAE 75W-140 Rear Axle Lubricant, Ford part number
XY-75W140-QL meeting Ford specification WSL-M2C192-A.7The Power Transfer Unit is lubricated for life with synthetic lube. Lubricant levels are not to be
checked or changed unless a leak is suspected or repair required. Replace Power Transfer Unit
lubricant with specified synthetic lubricant anytime the unit is submerged in water.
