CONGRATULATIONS
Congratulations on acquiring your new Mercury. Please take the time to
get well acquainted with your vehicle by reading this handbook. The
more you know and understand about your vehicle the greater the safety
and pleasure you will derive from driving it.
For more information on Ford Motor Company and its products visit the
following website:
•In the United States: www.ford.com
•In Canada: www.ford.ca
•In Mexico: www.ford.com.mx
•In Australia: www.ford.com.au
Additional owner information is given in separate publications.
This Owner’s Guide describes every option and model variant available
and therefore some of the items covered may not apply to your
particular vehicle. Furthermore, due to printing cycles it may describe
options before they are generally available.
Remember to pass on the Owner’s Guide when reselling the vehicle. It is
an integral part of the vehicle.
Fuel pump shut-off switch In the event of an accident the
safety switch will automatically cut off the fuel supply to the
engine. The switch can also be activated through sudden vibration (e.g.
collision when parking). To reset the switch, refer to the Fuel pump

SAFETY AND ENVIRONMENT PROTECTION
Warning symbols in this guide
How can you reduce the risk of personal injury and prevent possible
damage to others, your vehicle and its equipment? In this guide, answers
to such questions are contained in comments highlighted by the warning
triangle symbol. These comments should be read and observed.
Warning symbols on your vehicle
When you see this symbol, it is
imperative that you consult the
relevant section of this guide before
touching or attempting adjustment
of any kind.
Protecting the environment
We must all play our part in
protecting the environment. Correct
vehicle usage and the authorized
disposal of waste cleaning and
lubrication materials are significant
steps towards this aim. Information in this respect is highlighted in this
guide with the tree symbol.
BREAKING-IN YOUR VEHICLE
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,600 km (1,000 miles) of
new vehicle operation. Vary your speed to allow parts to adjust
themselves to other parts.
Drive your new vehicle at least 800 km (500 miles) before towing a
trailer.
Do not add friction modifier compounds or special break-in oils during
the first few thousand kilometers (miles) of operation, since these
additives may prevent piston ring seating. See Engine oil in the
Maintenance and specifications chapter for more information on oil
usage.

WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulb works. If any light remains on after starting the vehicle, have
the respective system inspected immediately.
Standard instrument cluster
Optional instrument cluster
Check engine
Illuminates briefly to ensure the
system is functional. If it comes on
after the engine is started, one of
the engine’s emission control
systems may be malfunctioning. The
light may illuminate without a driveability concern being noted and will
not require towing.

Light remains on:
Temporary malfunctions may cause your light to illuminate. Examples
are:
1. The vehicle has run out of fuel.
2. Poor fuel quality or water in the fuel.
3. The fuel cap may not have been properly installed and securely
tightened.
These temporary malfunctions can be corrected by filling the fuel tank
with high quality fuel of the recommended octane and/or properly
installing and securely tightening the fuel cap. After three driving cycles
without these or any other temporary malfunctions present, the light
should turn off. (A driving cycle consists of a cold engine startup
followed by mixed city/highway driving.) No additional vehicle service is
required.
If the light remains on, have your vehicle serviced at the first available
opportunity.
Light is blinking:
Engine misfire is occurring which could damage your catalytic converter.
You should drive in a moderate fashion (avoid heavy acceleration and
deceleration) and have your vehicle serviced at the first available
opportunity.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.
Check fuel cap
Illuminates when the fuel cap is not
installed correctly. Check the fuel
cap for proper installation. When
the fuel filler cap is properly
re-installed, the light(s) will turn off
after a period of normal driving. Continuing to operate the vehicle with
the check fuel cap light on, or a mis-installed fuel cap can activate the
Service Engine Soon/Check Engine warning light.
It may take a long period of time for the system to detect an
improperly installed fuel filler cap.
For more information, refer to Fuel filler cap in the Maintenance and
specifications chapter.

Brake system warning
•Standard instrument cluster
•Optional instrument cluster
To confirm the brake system
warning light is functional, it will
momentarily illuminate when the
ignition is turned to the ON position (alternatively for some vehicles
when the ignition is moved from the ON position to START position, the
light will momentarily illuminate prior to reaching the START position).
It also illuminates if the parking brake is engaged. If the brake system
warning light does not illuminate as described, seek service immediately.
Illumination after the parking brake is released indicates low brake fluid
level or a brake system malfunction and the brake system should be
serviced immediately by a qualified technician. Refer to Brakes in the
Driving chapter for more information.
Anti-lock brake system (ABS)
To confirm the anti-lock brake
system (ABS) warning light is
functional it will momentarily
illuminate when the ignition is
turned to the ON position
(alternatively for some vehicles when the ignition is moved from the ON
position to the START position, the light will momentarily illuminate just
prior to reaching the START position). If the light remains on, continues
to flash or fails to illuminate, have the ABS serviced immediately. If the
ABS light remains on, it means the anti-lock brake system has
malfunctioned and is disabled, however, the normal brake system will
still function unless the brake warning light also remains illuminated and
parking brake is off. Refer to Brakes in the Driving chapter for more
information.

charging properly.
Engine oil pressure (if equipped)
Illuminates when the oil pressure
falls below the normal range. Check
the oil level and add oil if needed.
Refer to Engine oil in the
Maintenance and specifications chapter.
Traction Control姟AdvancTrac active (if equipped)

Optional instrument cluster gauges
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 “H” and “C”). 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 to Engine coolant in the Maintenance
and specifications chapter.
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.

•Optional 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 and Check Engine/Service Engine Soon indicators illuminate,
refer to What you should know about fail-safe cooling in the
Maintenance and specifications chapter.
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 “L” and “H”);
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 oil in the Maintenance
and specifications chapter). If the
oil level is correct, have your vehicle checked at your dealership or by a
qualified technician.

possible.
Fuel gauge
Displays approximately how much fuel is in the fuel tank. The fuel gauge
may vary slightly when the vehicle is in motion or on a grade.
When refueling the vehicle from empty indication, the amount of fuel
that can be added will be less than the advertised capacity due to the
reserve fuel.
•Standard instrument cluster
•Optional instrument cluster
A minimum of four gallons must be
added or removed from the fuel
tank in order for the gauge to
