2007 Mercury Mariner Hybrid service interval

Driving while you tow
When towing a trailer:
•Keep your speed no faster than 70 mph (112 km/h) during the first
500 miles (800 km) of towing a trailer, and don’t make full throttle
starts.
•Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•Consult your local motor vehicle speed regulations for towing a trailer.
•Anticipate stops and brake gradually.
•Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to yourscheduled maintenance
informationfor more information.
Trailer towing tips
•Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
•Allow more distance for stopping with a trailer attached.
•If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
•If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCW, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube if not already so
equipped. Refer to theMaintenance and Specificationschapter for
the lubricant specification. Remember that regardless of the rear axle
lube used, do not tow a trailer for the first 500 miles (800 km) of a
new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (112 km/h) with no full throttle starts.
•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.

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.

If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer toAdding
engine coolantin this chapter.
Note:Automotive fluids are not interchangeable; do not use engine
coolant, antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding engine coolant
When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir,when the
engine is cool,until the appropriate fill level is obtained.
Do not add engine coolant when the engine is hot. Steam and
scalding liquids released from a hot cooling system can burn you
badly. Also, you can be burned if you spill coolant on hot engine parts.
Do not put engine coolant in the windshield washer fluid
container. If sprayed on the windshield, engine coolant could
make it difficult to see through the windshield.
•Add Motorcraft Premium Gold Engine Coolant or equivalent
meeting Ford specification WSS-M97B51-A1.Refer to
Maintenance product specifications and capacitiesin this chapter.
Note:Use of Motorcraft Cooling System Stop Leak Pellets or an
equivalent product meeting Ford specification WSS-M99B37-B6, may
darken the color of Motorcraft Premium Gold Engine Coolant from
yellow to golden tan.
•Do not add/mix an orange-colored, extended life coolant such
as Motorcraft Specialty Orange Engine Coolant, meeting Ford
specification WSS-M97B44-D, with the factory-filled coolant.
Mixing Motorcraft Specialty Orange Engine Coolant or any
orange-colored extended life product with your factory filled coolant
can result in degraded corrosion protection.
•A large amount of water without engine coolant may be added, in case
of emergency, to reach a vehicle service location. In this instance, the
cooling system must be drained and refilled with a 50/50 mixture of
engine coolant and distilled water as soon as possible. Water alone
(without engine coolant) can cause engine damage from corrosion,
overheating or freezing.

GENERAL MAINTENANCE INFORMATION
Why maintain your vehicle?
This guide describes the scheduled maintenance required for your
vehicle. Carefully following this schedule helps protect against major
repair expenses resulting from neglect or inadequate maintenance and
may also help to increase the value of your vehicle when you sell or
trade it.
It is your responsibility to see that all scheduled maintenance is
performed and that the materials used meet Ford engineering
specifications. Failure to perform scheduled maintenance specific in this
guide will invalidate warranty coverage on parts affected by the lack of
maintenance. Be sure receipts for completed maintenance are kept with
the vehicle and confirmation of the work performed is always recorded in
this guide.
Your Ford or Lincoln Mercury dealer, or Ford or Lincoln Mercury Quality
Care Center has factory trained technicians who can perform the
required maintenance using genuine Ford parts. They are committed to
meeting your service needs and to assuring your continuing satisfaction.
Protecting your investment
Maintenance is an investment that will pay dividends in the form of
improved reliability, durability and resale value. To ensure the proper
performance of your vehicle and its emission control systems, it is
imperative that scheduled maintenance be completed at the designated
intervals.
Your vehicle is very sophisticated and built with multiple complex
performance systems. Every manufacturer develops these systems using
different specifications and performance features. That’s why it’s
important to rely upon your Ford or Lincoln Mercury dealership to
properly diagnose and repair your vehicle.
Ford Motor Company has recommended maintenance intervals for
various parts and component systems based upon engineering testing.
Ford Motor Company relies upon this testing to determine the most
appropriate mileage for replacement of oils and fluids to protect your
vehicle at the lowest overall cost to you and recommends against
maintenance schedules that deviate from the scheduled maintenance
information.
Ford strongly recommends the use of genuine Ford replacement parts.
Parts other than Ford, Motorcraft or Ford authorized remanufactured

parts that are used for maintenance replacement or for the service of
components affecting emission control must be equivalent to genuine
Ford Motor Company parts in performance and durability. It is the
owner’s responsibility to determine the equivalency of such parts. Please
consult yourWarranty Guidefor complete warranty information.
Non-Ford approved chemicals or additives are not required for factory
recommended maintenance. In fact, Ford Motor Company recommends
against the use of such additive products unless specifically
recommended by Ford for a particular application.
Oil, fluids and flushing
In many cases, fluid discoloration is a normal operating characteristic of
the chemical compound and may not necessarily demonstrate that a fluid
needs to be changed. Oils and fluids identified in this guide should be
changed at the specified interval or in conjunction with a repair. Flushing
is a viable way to change fluid for many vehicle sub-systems during
scheduled maintenance and should only be done using the same fluid
required to finish the maintenance procedure, or a Ford approved
flushing chemical.
Engine Emissions label
Emissions information appears on the Engine Emissions label on the
underside of the hood. This decal identifies engine displacement and
provides certain engine specifications.
Any modification of the emissions control system could create liability
under federal law (U.S.) if made prior to sale and registration, under the
laws of some states if made thereafter. Further, federal law prohibits
vehicle manufacturers, dealers and other persons engaged in the
business of repairing, servicing, selling, leasing or trading motor vehicles
as well as fleet operations from knowingly removing or rendering an
emissions control system inoperative after sale and delivery to an
ultimate purchaser. In Canada, modifications of the emissions control
system could create liability under applicable federal or provincial laws.
