Engine coolant temperature gauge
Indicates the temperature of the engine coolant. At normal operating
temperature, the needle remains within the normal area (the area
between the ªHº and ªCº). If it enters the red section, the engine is
overheating. Stop the vehicle as soon as safely possible, switch off the
ignition and let it cool. Refer toEngine coolantin theMaintenance
and specificationschapter.
Never remove the coolant reservoir cap while the engine is
running or hot. Steam and scalding liquid from a hot cooling
system can burn you badly.
²Standard instrument cluster
²Optional instrument cluster
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level the gauge indication
will not be accurate. If the gauge enters the red section, the engine
coolant andCheck Engine/Service Engine Soonindicators illuminate,
refer toWhat you should know about fail-safe coolingin the
Maintenance and specificationschapter.

Engine oil pressure gauge (if equipped)
Indicates engine oil pressure. At
normal operating temperature, the
needle will be in the normal range
(the area between the ªLº and ªHº);
if the needle goes below the normal
range, stop the vehicle as soon as
safely possible and switch off the
engine immediately. Check the oil
level. Add oil if needed (refer to
Engine oilin theMaintenance
and specificationschapter). If the
oil level is correct, have your vehicle checked at your dealership or by a
qualified technician.
Battery voltage gauge (if equipped)
Indicates battery voltage. If the
pointer moves and stays outside the
normal operating range (as
indicated), have the vehicle's
electrical system checked as soon as
possible.

ELECTRONIC AUTOMATIC TEMPERATURE CONTROL (EATC)
SYSTEM (IF EQUIPPED)
The EATC system will maintain a
selected temperature and
automatically control airflow. You
can override automatic operation
with any of the override controls or
the fan speed control.
Turning the EATC on
Press AUTOMATIC, any of the
override controls or the fan speed
control. The EATC will only operate
when the vehicle is running.
Turning the EATC system off
Press OFF. The outside temperature
function will continue to operate
until the ignition is turned off.
Automatic operation
Press AUTOMATIC and select the desired temperature. The selected
temperature and the word AUTO will appear in the display window. The
EATC 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. Fan speed
remains automatic unless the fan speed thumbwheel is turned or the
steering wheel fan speed control (if equipped) is pressed.
When in AUTOMATIC and weather conditions require heat, air will be
sent to the floor. However, if the engine is not warm enough to provide
heat, the fan will be at a low speed and the air will be directed to the
windshield. In approximately 3
1¤2minutes or less, the fan speed will start
to increase and the airflow location will change to the floor area.
If unusual conditions exist (i.e.-window fogging, etc.), the manual
override controls allow you to select airflow locations and the fan control
allows you to adjust fan speed as necessary.

system. This system prevents the engine from being started unless a

non-Ford aftermarket remote start systems. Use of these systems may
result in vehicle starting problems and a loss of security protection.

Large metallic objects, electronic
devices on the key chain that can be
used to purchase gasoline or similar
items, or a second key on the same
key ring as thecoded keymay
cause vehicle starting issues. If
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 NOÐSTART 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:
²Use your spare key to start the
vehicle, or
²Have your vehicle towed to a
dealership or 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 ªNO-STARTº condition.
If an unprogrammed key is used in the ignition it will cause a
ªNO STARTº condition.
