2010 Mercury Grand Marquis engine

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. SeeGuarding against
exhaust fumesin 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. Do not allow the vehicle to idle
for more than 10 minutes at the higher engine RPM.
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 Restraintschapter.
2. Make sure the headlamps and vehicle accessories are off.
3. Make sure the gearshift is in P
(Park).
4. Make sure the parking brake is
set.

5. Turn the key to 3 (on) without
turning the key to 4 (start).
Some warning lights will briefly illuminate. SeeWarning lights and
chimesin theInstrument Clusterchapter for more information
regarding the warning lights.
Starting the engine
1. Turn the key to 3 (on) without
turning the key to 4 (start).
2. Turn the key to 4 (start), then
release the key as soon as the
engine starts. Excessive cranking
could damage the starter.
Note:If the engine does not start within five seconds on the first try,
turn the key to OFF, wait 10 seconds and try again. If the engine still
fails to start, press the accelerator to the floor and try again; this will
allow the engine to crank with the fuel shut off in case the engine is
flooded with fuel.
Cold weather starting (flexible fuel vehicles only)
The starting characteristics of all grades of E
85ethanol make it
unsuitable for use when ambient temperatures fall below 0°F (-18°C).
Consult your fuel distributor for the availability of winter grade ethanol.
As the outside temperature approaches freezing, ethanol fuel distributors
should supply winter grade ethanol (same as with unleaded gasoline). If
summer grade ethanol is used in cold weather conditions, 0°F to 32°F
(-18°C to 0°C), you may experience increased cranking times, rough idle
or hesitation until the engine has warmed up.

You may experience a decrease in peak performance when the engine is
cold when operating on E
85ethanol.
Do not crank the engine for more than 10 seconds at a time as starter
damage may occur. If the engine fails to start, turn the key to off and
wait 30 seconds before trying again.
Do not use starting fluid such as ether in the air intake system. Such
fluid could cause immediate explosive damage to the engine and possible
personal injury.
If you should experience cold weather starting problems on E
85ethanol,
and neither an alternative brand of E
85ethanol nor an engine block
heater is available, the addition of unleaded gasoline to your tank will
improve cold starting performance. Your vehicle is designed to operate
on E
85ethanol alone, unleaded gasoline alone, or any mixture of the two.
SeeChoosing the right fuelin theMaintenance and Specifications
chapter for more information on ethanol.
If the engine fails to start using the preceding instructions
(flexible fuel vehicles only)
1. Press and hold down the accelerator 1/3 to 1/2 way to floor, then
crank the engine.
2. When the engine starts, release the key, then gradually release the
accelerator pedal as the engine speeds up. If the engine still fails to start,
repeat Step 1.
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 1 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).
For flexible fuel vehicles, if operating with E
85ethanol, an engine block
heater must be used if ambient temperature is below 0°F (-18°C).
SeeCold weather startingearlier in this chapter for more information
on starting with ethanol.
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.
•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 system may consume anywhere between 400 watts or 1000 watts
of power per hour. 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.

TRACTION CONTROL (IF EQUIPPED)
The traction control system helps you maintain the stability and
steerability of your vehicle, especially on slippery road surfaces such as
snow- or ice-covered roads and gravel roads. The system will allow your
vehicle to make better use of available traction in these conditions.
During traction control operation,
the traction control active light will
illuminate, you may hear an electric
motor type of sound coming from
the engine compartment, and the
engine may not “rev-up” when you press farther on the accelerator. This
is normal system behavior and should be no reason for concern.
WARNING:Aggressive driving in any road conditions can cause
you to lose control of your vehicle increasing the risk of severe
personal injury or property damage. The occurrence of a traction
control event is an indication that at least some of the tires have
exceeded their ability to grip the road; this may lead to an increased
risk of loss of vehicle control, vehicle rollover, personal injury and
death. If you experience a severe road event, SLOW DOWN.
The traction control switch is
located on the instrument panel.
The traction control system will
automatically turn on every time the
ignition is turned off and on. When
disabled, the OFF will be
illuminated on the switch. The
traction control system will automatically turn on every time the ignition
is turned to off and on.
If you should become stuck in snow or ice or on a very slippery road
surface, try switching the traction control system off. Switching the
traction control system off may allow excess wheel spin to “dig” the
vehicle out and enable a successful “rocking” maneuver. When the
traction control system is off, an indicator light will illuminate and will
remain on until the system is turned back on or the ignition is turned off
and on. Remember to switch the traction control system back on once
the vehicle is no longer stuck.
If a system fault is detected, the traction control active light will
illuminate, the traction control button will not turn the system on or off
and your vehicle should be serviced by an authorized dealer.

STEERING
To help prevent damage to the power steering system, never hold the
steering wheel at its furthest turning points (until it stops) for more than
a few seconds when the engine is running.
It is also important to maintain a proper power steering fluid level in the
power steering fluid reservoir:
•Do not operate the vehicle with a low power steering pump fluid level.
SeePower steering fluidin theMaintenance and Specifications
chapter.
•Some noise is normal during operation. If the noise is excessive, check
for low power steering pump fluid level before seeking service by your
authorized dealer.
•Heavy or uneven steering efforts may be caused by low power steering
pump fluid level. Check for low power steering pump fluid level before
seeking service by your authorized dealer.
•Do not fill the power steering pump reservoir above the maximum
level, as this may result in leaks from the reservoir. SeePower
steering fluidin theMaintenance and Specificationschapter.
If the power steering system breaks down (or if the engine is off), you
can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper steering alignment
AIR SUSPENSION SYSTEM (IF EQUIPPED)
The air suspension system is designed to improve ride, handling and
general vehicle performance during:
•Certain road conditions
•Steering maneuvers
•Braking
•Accelerations
This system keeps the rear of your vehicle at a constant level by
automatically adding air or releasing air from the springs.
