Mercury Mountaineer (2010 year). Manual

Class III Trailer Hitch Safety Chain
Loops can be used as recovery
hooks.

Do not attach safety chains to the bumper.

Trailer brakes

Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer’s
specifications. The trailer brakes must meet local and Federal
regulations.

WARNING: Do not connect a trailer’s hydraulic brake system
directly to your vehicle’s brake system. Your vehicle may not

have enough braking power and your chances of having a collision
greatly increase.

The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.

Trailer lamps

Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. Contact
your authorized dealer or trailer rental agency for proper instructions
and equipment for hooking up trailer lamps.

WARNING: Never connect any trailer lighting to the vehicle’s
taillamp circuits, because it may damage the electrical system

resulting in fire. Contact your authorized dealer as soon as possible for
assistance in proper trailer tow wiring installation. Additional electrical
equipment may be required.

Driving while you tow

When towing a trailer:
• To ensure proper “break-in” of powertrain components, do not trailer

tow during the first 1,000 miles (1,600 km) of a new vehicle.

• To ensure proper “break-in” of powertrain components during the first

500 miles (800 km) of trailer towing, drive no faster than 70 mph
(113 km/h) with no 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.
• To eliminate excessive shifting, use a lower gear. This will also assist

in transmission cooling. For additional information, refer to Automatic
transmission operation in the Driving chapter.

• Under extreme conditions with large frontal trailers, high outside

temperatures and highway speeds, the coolant gauge may indicate
higher than normal coolant temperatures. If this occurs, reduce speed
until the coolant temperature returns to the normal range. Refer to
Engine coolant temperature gauge in the Instrument Cluster
chapter.

• 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 your scheduled maintenance
information for 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 GCWR, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube if not already so
equipped. Refer to the Maintenance and Specifications chapter for
the lubricant specification. Remember that regardless of the rear axle
lube used, do not tow a trailer for the first 1,000 miles (1,600 km) of a
new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (113 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.

• To aid in engine/transmission cooling and A/C efficiency during hot

weather while stopped in traffic, place the gearshift lever in P (Park).

• 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.

Launching or retrieving a boat

Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.

When backing down a ramp during boat launching or retrieval:
• do not allow the static water level to rise above the bottom edge of

the rear bumper.

• do not allow waves to break higher than 6 inches (15 cm) above the

bottom edge of the rear bumper.

Exceeding these limits may allow water to enter vehicle components:
• causing internal damage to the components.
• affecting driveability, emissions and reliability.
Replace the rear axle lubricant any time the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.

RECREATIONAL TOWING

Follow this guidelines if you have a need for recreational towing. An
example of recreational towing would be towing your vehicle behind a
motorhome. These guidelines are designed to ensure that your
transmission is not damaged.

Note: Put your climate control system in recirculated air mode to
prevent exhaust fumes from entering the vehicle. Refer to the Climate
controls chapter for more information.

All vehicles: Do not tow your vehicle with any wheels on the ground, as
vehicle or transmission damage may occur. It is recommended to tow
your vehicle with all four (4) wheels off the ground such as when using a
car-hauling trailer. Otherwise, no recreational towing is permitted.

In case of a roadside emergency with a disabled vehicle, see Wrecker
towing in the Roadside Emergencies chapter.

STARTING

Positions of the ignition

1. Off— locks the gearshift lever
and allows key removal. This
position also shuts the engine and
all electrical accessories off.

2. Accessory— allows the electrical
accessories such as the radio to
operate while the engine is not
running.

3. On— all electrical circuits
operational. Warning lights
illuminated. Key position when driving.
4. Start— cranks the engine. Release the key as soon as the engine
starts.

Preparing to start your vehicle
Engine starting is controlled by the powertrain control system.
This system meets all Canadian interference-causing equipment standard
requirements regulating the impulse electrical field strength of radio
noise.
When starting a fuel-injected engine, don’t press the accelerator before
or during starting. Only use the accelerator when you have difficulty
starting the engine. For more information on starting the vehicle, refer to
Starting the engine in this chapter.

WARNING: Extended idling at high engine speeds can produce
very high temperatures in the engine and exhaust system,

creating the risk of fire or other damage.

WARNING: Do not park, idle, or drive your vehicle in dry grass
or other dry ground cover. The emission system heats up the

engine compartment and exhaust system, which can start a fire.

WARNING: Do not start your vehicle in a closed garage or in
other enclosed areas. Exhaust fumes can be toxic. Always open

the garage door before you start the engine. See Guarding against
exhaust fumes in this chapter for more instructions.

Driving

WARNING: If you smell exhaust fumes inside your vehicle, have
your dealer inspect your vehicle immediately. Do not drive if you

smell exhaust fumes.

Important safety precautions

When the engine starts, the idle RPM runs faster to warm the engine. If
the engine idle speed does not slow down automatically, have the vehicle
checked.

If the vehicle is operated in a heavy snow storm or blowing snow
conditions, the engine air induction may become partially clogged with
snow and/or ice. If this occurs the engine may experience a significant
reduction in power output. At the earliest opportunity, clear all snow
and/or ice away for the air induction inlet.

Before starting the vehicle:

1. Make sure all occupants buckle their safety belts. For more
information on safety belts and their proper usage, refer to the Seating
and Safety Restraints chapter.

2. Make sure the headlamps and electrical accessories are off.
• Make sure the parking brake is

set.

Starting the engine

1. Turn the key to 3 (on) without
turning the key to 4 (start). If there
is difficulty in turning the key,
rotate the steering wheel until the
key turns freely. This condition may
occur when:
• the front wheels are turned
• a front wheel is against the curb
2. Turn the key to 4 (start), then
release the key as soon as the
engine begins cranking. Your vehicle has a computer assisted cranking
system that assists in starting the engine. After releasing the key from
the 4 (start) position, the engine may continue cranking for up to
10 seconds or until the vehicle starts.
Note: Cranking may be stopped at any time by turning the key to the off
position.

3. After idling for a few seconds, release the parking brake, apply the
brake, shift into gear and drive.

Note: If the engine does not start on the first try, turn the key to the off
position, wait 10 seconds and try Step 2 again. If the engine still fails to
start, press the accelerator to the floor and try Step 2 again, keeping the
accelerator on the floor until the engine begins to accelerate above
cranking speeds; this will allow the engine to crank with the fuel shut off
in case the engine is flooded with fuel.

Guarding against exhaust fumes

Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.

WARNING: If you smell exhaust fumes inside your vehicle, have
your dealer inspect your vehicle immediately. Do not drive if you

smell exhaust fumes.

Important ventilating information

If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least one inch (2.5 cm) or adjust the heating
or air conditioning to bring in fresh air.

ENGINE BLOCK HEATER (IF EQUIPPED)

An engine block heater warms the engine coolant which aids in starting
and allows the heater/defroster system to respond quickly. If your vehicle
is equipped with this system, your equipment includes a heater element
which is installed in your engine block and a wire harness which allows
the user to connect the system to a grounded 120 volt A/C electrical
source. The block heater system is most effective when outdoor
temperatures reach below 0°F (-18°C).

WARNING: Failure to follow engine block heater instructions
could result in property damage or physical injury.

WARNING: To reduce the risk of electrical shock, do not use
your heater with ungrounded electrical systems or two-pronged

(cheater) adapters.

Prior to using the engine block heater, follow these recommendations for
proper and safe operation:
• For your safety, use an outdoor extension cord that is product

certified by Underwriter’s Laboratory (UL) or Canadian Standards
Association (CSA). Use only an extension cord that can be used
outdoors, in cold temperatures, and is clearly marked

⬙Suitable for Use

with Outdoor Appliances.

⬙ Never use an indoor extension cord

outdoors; it could result in an electric shock or fire hazard.

• Use a 16 gauge outdoor extension cord, minimum.
• Use as short an extension cord as possible.
• Do not use multiple extension cords. Instead, use one extension cord

which is long enough to reach from the engine block heater cord to
the outlet without stretching.

• Make certain that the extension cord is in excellent condition (not

patched or spliced). Store your extension cord indoors at
temperatures above 32°F (0°C). Outdoor conditions can deteriorate
extension cords over a period of time.

• To reduce the risk of electrical shock, do not use your heater with

ungrounded electrical systems or two pronged (cheater) adapters.
Also ensure that the block heater, especially the cord, is in good
condition before use.

• Make sure that when in operation, the extension cord plug /engine

block heater cord plug connection is free and clear of water in order
to prevent possible shock or fire.

Driving

265

2010 Mountaineer (mnt)
Owners Guide (own2002), 1st Printing
USA (fus)

• Be sure that areas where the vehicle is parked are clean and clear of

all combustibles such as petroleum products, dust, rags, paper and
similar items.

• Be sure that the engine block heater, heater cord and extension cord

are solidly connected. A poor connection can cause the cord to
become very hot and may result in an electrical shock or fire. Be sure
to check for heat anywhere in the electrical hookup once the system
has been operating for approximately a half hour.

• Finally, have the engine block heater system checked during your fall

tune-up to be sure it’s in good working order.

How to use the engine block heater

Ensure the receptacle terminals are clean and dry prior to use. To clean
them, use a dry cloth.

Depending on the type of factory installed equipment, your engine block
heater will use .4 to 1.0 kilowatt-hours of energy per hour of use. Your
factory installed block heater system does not have a thermostat;
however, maximum temperature is attained after approximately three
hours of operation. Block heater operation longer than three hours will
not improve system performance and will unnecessarily use additional
electricity.

Make sure system is unplugged and properly stowed before driving the
vehicle. While not in use, make sure the protective cover seals the
prongs of the engine block heater cord plug.

BRAKES

Occasional brake noise is normal. If a metal-to-metal, continuous grinding
or continuous squeal sound is present, the brake linings may be worn-out
and should be inspected by an authorized dealer. If the vehicle has
continuous vibration or shudder in the steering wheel while braking, the
vehicle should be inspected by an authorized dealer.

Refer to Brake system warning
light in the Instrument Cluster
chapter for information on the brake
system warning light.

Four-wheel anti-lock brake system (ABS)

Your vehicle is equipped with an Anti-lock Braking System (ABS). This
system helps you maintain steering control during emergency stops by
keeping the brakes from locking. Noise from the ABS pump motor and

BRAKE

Driving

266

2010 Mountaineer (mnt)
Owners Guide (own2002), 1st Printing
USA (fus)

brake pedal pulsation may be observed during ABS braking and the
brake pedal may suddenly travel a little farther as soon as ABS braking is
done and normal brake operation resumes. These are normal
characteristics of the ABS and should be no reason for concern.

Using ABS

When hard braking is required, apply continuous force on the brake
pedal; do not pump the brake pedal since this will reduce the
effectiveness of the ABS and will increase your vehicle’s stopping
distance. The ABS will be activated immediately, allowing you to retain
steering control during hard braking and on slippery surfaces. However,
the ABS does not decrease stopping distance.

ABS warning lamp

The ABS lamp in the instrument
cluster momentarily illuminates
when the ignition is turned on. If
the light does not illuminate during
start up, remains on or flashes, the
ABS may be disabled and may need to be serviced.

Even when the ABS is disabled,
normal braking is still effective. If
your BRAKE warning lamp
illuminates with the parking brake
released, have your brake system
serviced immediately.

Parking brake

Apply the parking brake whenever
the vehicle is parked. To set the
parking brake, press the parking
brake pedal down until the pedal
stops.

The BRAKE warning lamp in the
instrument cluster illuminates and
remains illuminated (when the
ignition is turned on) until the
parking brake is released.

WARNING: Always set the parking brake fully and make sure
that the gearshift is securely latched in P (Park).

WARNING: If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be

working properly. See your authorized dealer.

The parking brake is not recommended to stop a moving vehicle.
However, if the normal brakes fail, the parking brake can be used to stop
your vehicle in an emergency. Since the parking brake applies only the
rear brakes, the vehicle’s stopping distance will increase greatly and the
handling of your vehicle will be adversely affected.

Pull the release lever to release the
brake. Driving with the parking
brake on will cause the brakes to
wear out quickly and reduce fuel
economy.

STABILITY ENHANCEMENT SYSTEM

WARNING: Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire

construction and/or wheel/tire size may change the handling
characteristics of the vehicle and may adversely affect the performance
of the AdvanceTrac

威 with RSC威 system. In addition, installing any

stereo loudspeakers may interfere with and adversely affect the
AdvanceTrac

威 with RSC威 system. Install any aftermarket stereo

loudspeaker as far as possible from the front center console, the
tunnel, and the front seats in order to minimize the risk of interfering
with the AdvanceTrac

威 with RSC威 sensors. Reducing the effectiveness

of the AdvanceTrac

威 with RSC威 system could lead to an increased risk

of loss of vehicle control, vehicle rollover, personal injury and death.

WARNING: Remember that even advanced technology cannot
defy the laws of physics. It’s always possible to lose control of a

vehicle due to inappropriate driver input for the conditions. Aggressive
driving on any road condition can cause you to lose control of your
vehicle increasing the risk of personal injury or property damage.
Activation of the AdvanceTrac

威 with RSC威 system is an indication that

at least some of the tires have exceeded their ability to grip the road;
this could reduce the operator’s ability to control the vehicle,
potentially resulting in a loss of vehicle control, vehicle rollover,
personal injury and death. If your AdvanceTrac

威 with RSC威 system

activates, SLOW DOWN.

WARNING: If a failure has been detected within the
AdvanceTrac

威 with RSC威 system, the ⬙sliding car⬙ icon

will

illuminate steadily. Verify that the AdvanceTrac

威 with RSC威 system is

not manually disabled (push the AdvanceTrac

威 with RSC威 “Off “

button located on the center of the instrument panel). If the

⬙sliding

car

⬙ icon

still illuminates steadily, have the system serviced by an

The AdvanceTrac

威 with RSC威 system provides the following stability

enhancement features for certain driving situations:
• Traction Control (TCS), which functions to help avoid drive-wheel

spin and loss of traction.

• Electronic Stability Control (ESC), which functions to help avoid skids

or lateral slides

• Roll Stability Control™ (RSC威), which functions to help avoid a

vehicle roll-over.

The AdvanceTrac

威 with RSC威 system automatically enables each time

the engine is started. All features of the AdvanceTrac

威 with RSC威 system

(TCS, ESC, and RSC

威) are active and monitor the vehicle from start-up.

However, the system will only intervene if the driving situation requires
it.

The AdvanceTrac

威 with RSC威

system includes an AdvanceTrac

威

with RSC

威 ⬙Off⬙ button on the

center of the instrument panel, and
a “sliding car” icon

in the

instrument cluster. The “sliding car”
icon

in the instrument cluster will illuminate temporarily during

start-up as part of a normal system self-check, or during driving if a
driving situation causes the AdvanceTrac

威 with RSC威 system to operate.

If the “sliding car” icon

illuminates steadily, verify that the

AdvanceTrac

威 with RSC威 system is not manually disabled by pressing

the AdvanceTrac

威 with RSC威 ⬙Off⬙ button located on the center stack of

the instrument panel. If the “sliding car” icon

remains steadily

illuminated, or if the message center (if equipped) displays SERVICE
RSC NOW, have the system serviced by an authorized dealer
immediately.

When AdvanceTrac

威 with RSC威 performs a normal system self-check,

some drivers may notice a slight movement of the brake, and/or a
rumble, grunting, or grinding noise after startup and when driving off.

When an event occurs that activates AdvanceTrac

威 with RSC威 you may

experience the following:
• A slight deceleration of the vehicle
• The “sliding car”

indicator light will flash.

• A vibration in the pedal when your foot is on the brake pedal

Driving

270

2010 Mountaineer (mnt)
Owners Guide (own2002), 1st Printing
USA (fus)

• If the driving condition is severe and your foot is not on the brake, the

brake pedal may move as the systems applies higher brake forces. You
may also hear a whoosh of air from under the instrument panel during
this severe condition.

• The brake pedal may feel stiffer than usual.
Traction Control (TCS)

Traction Control is a driver aid feature that helps your vehicle maintain
traction of the wheels, typically when driving on slippery and/or hilly
road surfaces, by detecting and controlling wheel spin.

Excessive wheel spin is controlled in two ways, which may work
separately or in tandem: Engine Traction Control and Brake Traction
Control. Engine Traction Control works to limit drive-wheel spin by
momentarily reducing engine power. Brake Traction Control works to
limit wheel spin by momentarily applying the brakes to the wheel that is
slipping. Traction Control is most active at low speeds.

During Traction Control events the “sliding car” icon

in the

instrument cluster will flash.

If the Traction Control system is activated excessively in a short period
of time, the braking portion of the system may become temporarily
disabled to allow the brakes to cool down. In this situation, Traction
Control will use only engine power reduction or transfer to help control
the wheels from over-spinning. When the brakes have cooled down, the
system will regain all features. Anti-lock braking, RSC

威, and ESC are not

affected by this condition and will continue to function during the
cool-down period.

The Engine Traction Control and Brake Traction Control system may be
deactivated in certain situations. See the Switching Off AdvanceTrac

威

with RSC

威 section following.

Electronic Stability Control (ESC)

Electronic Stability Control (ESC) may enhance your vehicle’s directional
stability during adverse maneuvers, for example when cornering severely
or avoiding objects in the roadway. ESC operates by applying brakes to
one or more of the wheels individually and, if necessary, reducing engine
power if the system detects that the vehicle is about to skid or slide
laterally.

During Electronic Stability Control events the “sliding car” icon

in the

instrument cluster will flash.

Driving

271

2010 Mountaineer (mnt)

Certain adverse driving maneuvers may activate the Electronic Stability
Control system, which include but are not limited to:
• Taking a turn too fast
• Maneuvering quickly to avoid an accident, pedestrian or obstacle
• Driving over a patch of ice or other slippery surfaces
• Changing lanes on a snow-rutted road
• Entering a snow-free road from a snow-covered side street, or vice

versa

• Entering a paved road from a gravel road, or vice versa
• Cornering while towing a heavily loaded trailer (refer to Trailer

towing in the Tires, Wheels and Loading chapter).

The Electronic Stability Control system may be deactivated in certain
situations. See the Switching Off AdvanceTrac

威 with RSC威 section

following.

Roll Stability Control™ (RSC

威)

Roll Stability Control™ (RSC

威) may help to maintain roll stability of the

vehicle during adverse maneuvers. RSC

威 operates by detecting the

vehicle’s roll motion and the rate at which it changes and by applying the
brakes to one or more wheels individually.

During an event that activates the Roll Stability Control™ (RSC

威) the

“sliding car” icon

in the instrument cluster will flash.

Certain adverse driving maneuvers may activate the Roll Stability
Control™ system, which include:
