To aid in side window defogging/demisting in cold weather conditions:
1. Select Vent.
2. Set the temperature control to full heat.
3. Set the fan speed to full fan.
4. Direct the outer panel vents towards the side windows.
5. To increase airflow to the outer panel vents, close the central panel
vents.
Do not place objects on top of the instrument panel as these
objects may become projectiles in a collision or sudden stop.
ELECTRONIC AUTOMATIC TEMPERATURE CONTROL (EATC)
SYSTEM (IF EQUIPPED)
The EATC system will maintain a
selected temperature and
automatically control the fan speed
and airflow location.
Automatic operation
Press Automatic/AUTO and select the desired temperature. The system
will either heat or cool to achieve the selected temperature. The system
will automatically determine fan speed, airflow location and if outside air
or recirculated air is required.
When in automatic operation and weather conditions require heat, the
air will be sent to the floor ducts. However, until the engine has warmed,
the fan speed will operate at a low speed and airflow will be directed to
the windshield defroster ducts. Upon engine warm up, the system will
automatically direct airflow to the floor ducts and operate the required
fan speed to achieve the selected temperature.
If unusual conditions exist (i.e.-window fogging, etc.), the manual
overrides allow you to select airflow locations and the fan speed. To
return to automatic operation, press Automatic/AUTO.

If any of these items are present, you need to keep these objects from
touching thecoded keywhile starting the engine. These objects and
devices cannot damage thecoded key,but can cause a momentary “no
start” condition if they are too close to the key during engine start. If a
problem occurs, turn ignition OFF and restart the engine with all other
objects on the key ring held away from the ignition key. Check to make
sure thecoded keyis an approved Mercurycoded key.
If your keys are lost or stolen you will need to do the following:
•Use your spare key to start the vehicle, or
•Have your vehicle towed to a dealership or a locksmith. The key codes
will need to be erased from your vehicle and new key codes will need
to be re-coded.
Replacing coded keys can be very costly and you may want to store an
extra programmed key away from the vehicle in a safe place to prevent
an unforeseen inconvenience.
The correctcoded keymust be used for your vehicle. The use of the
wrong type ofcoded keymay lead to a “no start” condition.
If an unprogrammed key is used in the ignition it will cause a “no
start” condition.
Programming spare keys
A maximum of eight keys can be coded to your vehicle. Only
SecuriLock
keys can be used. To program acoded keyyourself, you
will need two previously programmedcoded keys(keys that already
operate your vehicle’s engine) and the new unprogrammed key(s) readily
accessible for timely implementation of each step in the procedure.
If two previously programmed coded keys are not available, you must
bring your vehicle to your dealership to have the spare coded key(s)
programmed.
Please read and understand the entire procedure before you begin.

STARTING
Positions of the ignition
1. ACCESSORY, allows the electrical
accessories such as the radio to
operate while the engine is not
running.
2. LOCK, locks automatic
transmission gearshift lever and
allows key removal.
3. OFF, shuts off the engine and all
accessories without locking the
steering wheel. This position also allows the automatic transmission shift
lever to be moved from the P (Park) position without the brake pedal
being depressed.
When the key is in the ignition OFF position, the automatic
transmission shift lever can be moved from the P (Park) position
without the brake pedal depressed. To avoid unwanted vehicle
movement, always set the parking brake.
4. ON, all electrical circuits operational. Warning lights illuminated. Key
position when driving.
5. 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, avoid pressing 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 toStarting the enginein this chapter.
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.

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.
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.
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).

Make sure the corresponding lights illuminate or illuminate briefly. If a
light fails to illuminate, have the vehicle serviced.
•If the driver’s safety belt is fastened, the
light may not illuminate.
Starting the engine
1. Turn the key to 4 (ON) without
turning the key to 5 (START).
2. Turn the key to 5 (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 3 (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.
Using the engine block heater (if equipped)
Use of an engine block heater is strongly recommended if you live in a
region where temperatures reach -23° C (-10° F) or below. For best
results, plug the heater in at least three hours before starting the vehicle.
The heater can be plugged in the night before starting the vehicle.

To reduce the risk of electrical shock, do not use your heater
with ungrounded electrical systems or two-pronged (cheater)
adapters.
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
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 2.5 cm (one inch) or adjust the heating
or air conditioning to bring in fresh air.
BRAKES
Your service brakes are self-adjusting. Refer to the scheduled
maintenance guide for scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle’s brake system. In normal
operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
road dust, salt or mud. If a “metal-to-metal,” “continuous grinding” or
“continuous squeal” sound is present while braking, the brake linings
may be worn-out and should be inspected by a qualified service
technician.
If you are driving down a long or steep hill, shift to a lower gear.
Do not apply your brakes continuously, as they may overheat
and become less effective.
Under normal operating conditions, brake dust may accumulate on the
wheels. Some brake dust is inevitable as brakes wear and does not
contribute to brake noise. The use of modern friction materials with
