Mercury Sable (2009 year). Instruction — part 13

VEHICLE LOADING – WITH AND WITHOUT A TRAILER

This section will guide you in the proper loading of your vehicle and/or
trailer, to keep your loaded vehicle weight within its design rating
capability, with or without a trailer. Properly loading your vehicle will
provide maximum return of vehicle design performance. Before loading
your vehicle, familiarize yourself with the following terms for determining
your vehicle’s weight ratings, with or without a trailer, from the vehicle’s
Tire Label or Safety Compliance Certification Label:

Base Curb Weight – is the weight of the vehicle including a full tank of
fuel and all standard equipment. It does not include passengers, cargo, or
optional equipment.

Vehicle Curb Weight – is the weight of your new vehicle when you
picked it up from your authorized dealer plus any aftermarket
equipment.

Tires, Wheels and Loading

193

Payload – is the combined weight of cargo and passengers that the
vehicle is carrying. The maximum payload for your vehicle can be found
on the Tire Label on the B-Pillar or the edge of the driver’s door
(vehicles exported outside the US and Canada may not have a Tire
Label). Look for “THE COMBINED WEIGHT OF OCCUPANTS AND
CARGO SHOULD NEVER EXCEED XXX kg OR XXX lb.” for
maximum payload. The payload listed on the Tire Label is the maximum
payload for the vehicle as built by the assembly plant. If any aftermarket
or authorized-dealer installed equipment has been installed on the
vehicle, the weight of the equipment must be subtracted from the
payload listed on the Tire Label in order to determine the new payload.

WARNING: The appropriate loading capacity of your vehicle can
be limited either by volume capacity (how much space is

available) or by payload capacity (how much weight the vehicle should
carry). Once you have reached the maximum payload of your vehicle,
do not add more cargo, even if there is space available. Overloading or
improperly loading your vehicle can contribute to loss of vehicle
control and vehicle rollover.

Example only:

Cargo Weight – includes all weight added to the Base Curb Weight,
including cargo and optional equipment. When towing, trailer tongue load
weight is also part of cargo weight.

GAW (Gross Axle Weight) – is the total weight placed on each axle
(front and rear) – including vehicle curb weight and all payload.

2009 Sable (mgo)

Tires, Wheels and Loading

195

GAWR (Gross Axle Weight Rating) – is the maximum allowable
weight that can be carried by a single axle (front or rear). These
numbers are shown on the Safety Compliance Certification Label
located on the B-Pillar or the edge of the driver’s door. The total
load on each axle must never exceed its GAWR.

Note: For trailer towing information refer to Trailer towing found in
this chapter or the RV and Trailer Towing Guide provided by your
authorized dealer.

GVW (Gross Vehicle Weight) – is the Vehicle Curb Weight + cargo +
passengers.

GVWR (Gross Vehicle Weight
Rating) – is the maximum
allowable weight of the fully loaded
vehicle (including all options,
equipment, passengers and cargo).
The GVWR is shown on the
Safety Compliance Certification
Label located on the B-Pillar or
the edge of the driver’s door.
The GVW must never exceed the
GVWR.

WARNING: Exceeding the Safety Compliance Certification Label
vehicle weight rating limits could result in substandard vehicle

handling or performance, engine, transmission and/or structural
damage, serious damage to the vehicle, loss of control and personal
injury.

GCW (Gross Combined Weight) – is the weight of the loaded vehicle
(GVW) plus the weight of the fully loaded trailer.

GCWR (Gross Combined Weight Rating) – is the maximum allowable
weight of the vehicle and the loaded trailer – including all cargo and
passengers – that the vehicle can handle without risking damage.
(Important: The towing vehicles’ braking system is rated for operation at
GVWR, not at GCWR. Separate functional brakes should be used for safe
control of towed vehicles and for trailers where the GCW of the towing
vehicle plus the trailer exceed the GVWR of the towing vehicle. The
GCW must never exceed the GCWR.

Maximum Loaded Trailer Weight – is the highest possible weight of a
fully loaded trailer the vehicle can tow. It assumes a vehicle with only
mandatory options, no cargo (internal or external), a tongue load of
10–15% (conventional trailer), and driver only (150 lb. [68 kg]). Consult
your authorized dealer (or the RV and Trailer Towing Guide
provided by your authorized dealer) for more detailed
information.

WARNING: Do not exceed the GVWR or the GAWR specified on
the Safety Compliance Certification Label.

WARNING: Do not use replacement tires with lower load
carrying capacities than the original tires because they may

lower the vehicle’s GVWR and GAWR limitations. Replacement tires
with a higher limit than the original tires do not increase the GVWR
and GAWR limitations.

WARNING: Exceeding any vehicle weight rating limitation could
result in serious damage to the vehicle and/or personal injury.

Steps for determining the correct load limit:

1. Locate the statement “The combined weight of occupants and cargo
should never exceed XXX kg or XXX lbs.” on your vehicle’s placard.

2. Determine the combined weight of the driver and passengers that will
be riding in your vehicle.

3. Subtract the combined weight of the driver and passengers from
XXX kg or XXX lbs.

4. The resulting figure equals the available amount of cargo and luggage
load capacity. For example, if the “XXX” amount equals 1,400 lbs. and
there will be five 150 lb. passengers in your vehicle, the amount of
available cargo and luggage load capacity is 650 lbs. (1400–750 (5 x 150)
= 650 lb.). In metric units (635–340 (5 x 68) = 295 kg.)

5. Determine the combined weight of luggage and cargo being loaded on
the vehicle. That weight may not safely exceed the available cargo and
luggage load capacity calculated in Step 4.

6. If your vehicle will be towing a trailer, load from your trailer will be
transferred to your vehicle. Consult this instruction to determine how this
reduces the available cargo and luggage load capacity of your vehicle.

The following gives you a few examples on how to calculate the available
amount of cargo and luggage load capacity:
• Another example for your vehicle with 1,400 lb. (635 kg) of cargo and

luggage capacity. You decide to go golfing. Is there enough load
capacity to carry you, 4 of your friends and all the golf bags? You and
four friends average 220 lb. (99 kg) each and the golf bags weigh
approximately 30 lb. (13.5 kg) each. The calculation would be: 1,400 -
(5 x 220) - (5 x 30) = 1,400 - 1,100 - 150 = 150 lb. Yes, you have
enough load capacity in your vehicle to transport four friends and
your golf bags. In metric units, the calculation would be: 635 kg - (5 x
99 kg) - (5 x 13.5 kg) = 635 - 495 - 67.5 = 72.5 kg.

• A final example for your vehicle with 1,400 lb. (635 kg) of cargo and

luggage capacity. You and one of your friends decide to pick up
cement from the local home improvement store to finish that patio
you have been planning for the past 2 years. Measuring the inside of
the vehicle with the rear seat folded down, you have room for
12-100 lb. (45 kg) bags of cement. Do you have enough load capacity

2009 Sable (mgo)
Owners Guide, 2nd Printing
USA (fus)

Tires, Wheels and Loading

198

to transport the cement to your home? If you and your friend each
weigh 220 lb. (99 kg), the calculation would be: 1,400 - (2 x 220) -
(12 x 100) = 1,400 - 440 - 1,200 = - 240 lb. No, you do not have
enough cargo capacity to carry that much weight. In metric units, the
calculation would be: 635 kg - (2 x 99 kg) - (12 x 45 kg) = 635 - 198 -
540 = -103 kg. You will need to reduce the load weight by at least
240 lb. (104 kg). If you remove 3-100 lb. (45 kg) cement bags, then
the load calculation would be:

1,400 - (2 x 220) - (9 x 100) = 1,400 - 440 - 900 = 60 lb. Now you
have the load capacity to transport the cement and your friend home.
In metric units, the calculation would be: 635 kg - (2 x 99 kg) - (9 x
45 kg) = 635 - 198 - 405 = 32 kg.

The above calculations also assume that the loads are positioned in your
vehicle in a manner that does not overload the Front or the Rear Gross
Axle Weight Rating specified for your vehicle on the Safety Compliance
Certification Label found on the edge of the driver’s door.

TRAILER TOWING

Your vehicle is capable of towing a trailer up to 1,000 lb. (454 kg) gross
trailer weight with a maximum tongue load of 100 lb. (45 kg). Do not
tow a trailer until your vehicle has been driven at least 500 miles
(800 km).

Towing a trailer places an additional load on your vehicle’s engine,
transmission, brakes, tires and suspension. Inspect these components
carefully after towing.

WARNING: Do not exceed the GVWR or the GAWR specified on
the certification label.

WARNING: Towing trailers beyond the maximum recommended
gross trailer weight exceeds the limit of the vehicle and could

result in engine damage, transmission damage, structural damage, loss
of vehicle control, vehicle rollover and personal injury.

Preparing to tow

Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. Contact your authorized dealer or a
reliable trailer dealer as soon as possible if you require assistance.

Hitches

Do not use hitches that clamp onto the vehicle bumper. Use a load
carrying hitch. You must distribute the load in your trailer so that
10–15% of the total weight of the trailer is on the tongue.

Safety chains

Always connect the trailer’s safety chains to the frame or hook retainers
of the vehicle hitch. To connect the trailer’s safety chains, cross the
chains under the trailer tongue and allow slack for turning corners.

If you use a rental trailer, follow the instructions that the rental agency
gives to you.

Do not attach safety chains to the bumper.

Trailer brakes

Electric brakes and instruction, 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. Do not
connect trailer lamps directly to your vehicle’s tail lamps. This can cause
damage to your vehicle’s electrical system. Contact your authorized
dealer or trailer rental agency for proper instructions and equipment for
hooking up trailer lamps.

Driving while you tow

When towing a trailer:
• 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.

• It is recommended to select the L (Low) gear position when additional

engine braking is needed. In situations such as prolonged downhill
driving on steep grades (i.e., driving in mountainous areas), additional
engine braking is needed to reduce the load on the vehicle’s regular
brake system to prevent them from overheating.

• Anticipate stops and brake gradually.
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.

• 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.

RECREATIONAL TOWING

Follow these guidelines for your specific powertrain combination to tow
your vehicle for personal travel (such as behind a motor home or a
truck).

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.

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

These guidelines are designed to prevent damage to your vehicle.

Front Wheel Drive (FWD) vehicles:

Tow your Front Wheel Drive vehicle with all four wheels on the ground
or with the front wheels off the ground by using a tow dolly. If you are
using a tow dolly follow the instructions specified by the equipment
provider.

All Wheel Drive (AWD) vehicles:

Tow your All Wheel Drive vehicle with all four wheels on the ground or
with all four wheels off the ground using a vehicle transport trailer. Do
not tow your All Wheel Drive vehicle with the front wheels off
the ground (by using a tow dolly) and the rear wheels on the
ground. This will cause damage to your AWD system. If you are using a
vehicle transport trailer, follow the instruction specified by the
equipment provider.

Note: If you tow your vehicle with all four wheels on the ground, follow
these instructions:
• Tow only in the forward direction.
• Release the parking brake.
• Place the transmission shift lever in (N) Neutral.
• Place the ignition in the accessory position (refer to Starting in the

Driving chapter).

• Do not exceed 65 mph (105 km/h)
• Start the engine and allow it to run for five minutes at the beginning

of each day and at each fuel stop.

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.

Starting 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.

To avoid potential transmission damage at extremely cold temperatures
(below -20°F [-30°C]), it is recommended that the vehicle be warmed up
to normal operating temperature before driving at highway speeds above
50 mph (80 km/h). Normal operating temperature is normally reached
after 10 minutes of moderate driving or idling.

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.

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

A computer system controls the engine’s idle revolutions per minute
(RPM). When the engine starts, the idle RPM runs higher than normal in
order to warm the engine. If the engine idle speed does not slow down
automatically, have the vehicle checked.

Before starting the vehicle:

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

2. Make sure vehicle accessories are off.
• Make sure the parking brake is

set.

• Make sure the gearshift lever is in

P (Park).

3. Turn the key to 3 (on) without
turning the key to 4 (start).

Some warning lights will briefly illuminate. See Warning lights and
chimes in the Instrument Cluster chapter for more information
regarding the warning lights.

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

2009 Sable (mgo)
Owners Guide, 2nd Printing
USA (fus)

Driving

205

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, 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.

2009 Sable (mgo)
Owners Guide, 2nd Printing
USA (fus)

Driving

206

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.

• 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 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.

Brake Assist

The Brake Assist system provides full braking force during panic braking
situations. It detects a rapid application of the brake pedal and uses the
ABS system to achieve maximum braking pressure. Once a panic brake
