warning light LINCOLN MKZ HYBRID 2012 Service Manual

3. 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 vehicle
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.
After releasing the key from the 4
(start) position, a vehicle symbol
(called the Ready Indicator Light)
will illuminate in the instrument
cluster to indicate the vehicle is
ready to drive. The engine may not start because this hybrid vehicle is
equipped with Silent Key Start (SKS). This fuel saving feature allows
your vehicle to be “ready to drive” without requiring the gas engine to be
running. This light will remain on while the vehicle is on, whether the
engine is running or not, to indicate the vehicle is capable of movement
(using its electric motor, engine, or both). The vehicle’s computer will
determine if an engine start is required at key-on. The engine will start if
it is necessary for cabin heating or windshield defrost. The engine will
also be started when outside temperatures are low.
Note:The vehicle may be turned off at any time by turning the key to
the off position.

3. Once the “Ready Indicator Light” is on, release the parking brake,
apply the brake, shift into gear and drive.
Note:After the engine has started the first time, it may stop running to
conserve fuel after it is warmed-up and the battery is sufficiently
charged.
Note:If the vehicle does not start, put the gearshift lever into P (Park),
turn the ignition off, wait 10 seconds, then attempt to start the vehicle
again. If the vehicle still does not start, it may require refueling, jump
starting, or service. For information on jump starting the vehicle, refer to
Jump startingin theRoadside Emergencieschapter.
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)
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.
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).

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 toWarning lights and
chimesin theInstrument 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. The ABS operates by detecting the
onset of wheel lockup during brake application and compensates for this
tendency. Noise from the ABS pump motor and brake pedal pulsation
may be observed during ABS braking; any pulsation or mechanical noise
you may feel or hear is normal. In addition, the ABS performs a
self-check after you start the engine and begin to drive away. A brief
mechanical noise may be heard during this test. This is normal.

ABS warning lamp
The ABS lamp in the instrument
cluster momentarily illuminates
when the ignition is turned on. If
the light does not illuminate during
start up, remains on or flashes, the
ABS may be disabled and may need to be serviced.
Even when the ABS is disabled and
the ABS light is on, normal braking
is still effective. If your BRAKE
warning lamp illuminates with the
parking brake released, have your
brake system serviced immediately.
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
full steering control during hard braking and on slippery surfaces.
However, the ABS does not decrease stopping distance and does not
decrease the time necessary to apply the brakes.
Regenerative Braking System (RBS)
Your vehicle uses a feature known as regenerative braking. This is used
to simulate the engine braking of an internal combustion engine and
assist the standard brake system while recovering some of the energy of
motion and storing it in the battery to improve fuel economy. The
standard brake system is designed to fully stop the car if regenerative
braking is not available. During regenerative braking, the motor is spun
as a generator to create electrical current. This recharges the high
voltage battery and slows the vehicle. In effect, once the accelerator
pedal is released, the motor changes from an energy user to an energy
producer.
When the accelerator pedal is released or the brake pedal is applied, the
brake controller automatically detects the amount of deceleration
requested and optimizes how much of the deceleration will be produced
by regenerative braking. The remaining portion is generated by standard
friction braking. When the battery is almost fully charged, the amount of
regenerative braking is limited to avoid overcharging, and the requested
deceleration is produced by standard friction braking alone.

Regenerative braking does not take the place of the standard friction
brakes; it only assists them. Regenerative braking has also been designed
to interact with the anti-lock brake system (ABS). Regenerative braking
is disabled when the ABS is activated or the battery is fully charged.
Brake over accelerator
This vehicle is equipped with a brake over accelerator feature. In the
event the accelerator pedal becomes stuck or entrapped, applying steady
and firm pressure to the brake pedal will both slow the vehicle and
reduce engine power. If you experience this condition, apply the brakes
and bring your vehicle to a safe stop. Turn the engine off, shift to P
(Park) and apply the parking brake, and then inspect the accelerator
pedal for any interferences. If none are found and the condition persists,
have your vehicle towed to the nearest authorized dealer.
Parking brake
To set the parking brake (1), pull
the parking brake handle up as far
as possible.
The BRAKE warning lamp will
illuminate and will remain
illuminated until the parking brake
is released.
To release, press and hold the button (2), pull the handle up slightly,
then push the handle down.
WARNING:Always set the parking brake fully and make sure
that the gearshift is securely latched in P (Park).
WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer as soon as possible.

ADVANCETRACSTABILITY ENHANCEMENT SYSTEM
Your vehicle is equipped with the AdvanceTracsystem. The
AdvanceTracsystem provides the following stability enhancement
features for certain driving situations:
•Traction control system (TCS), which functions to help avoid
drive-wheel spin and loss of traction.
•Electronic stability control (ESC), which functions to help avoid skids
or lateral slides
WARNING:Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction and/or wheel/tire size may change the handling
characteristics of the vehicle and may adversely affect the performance
of the AdvanceTracsystem. In addition, installing any stereo
loudspeakers may interfere with and adversely affect the AdvanceTrac
system. Install any aftermarket stereo loudspeaker as far as possible from
the front center console, the tunnel, and the front seats in order to
minimize the risk of interfering with the AdvanceTracsensors. Reducing
the effectiveness of the AdvanceTracsystem could lead to an increased
risk of loss of vehicle control, vehicle rollover, personal injury and death.
WARNING:Remember that even advanced technology cannot
defy the laws of physics. It’s always possible to lose control of a
vehicle due to inappropriate driver input for the conditions. Aggressive
driving on any road condition can cause you to lose control of your
vehicle increasing the risk of personal injury or property damage.
Activation of the AdvanceTracsystem is an indication that at least
some of the tires have exceeded their ability to grip the road; this
could reduce the operator’s ability to control the vehicle potentially
resulting in a loss of vehicle control, vehicle rollover, personal injury
and death. If your AdvanceTracsystem activates, SLOW DOWN.
WARNING:If a failure has been detected within the
AdvanceTracsystem, the stability control light will illuminate
steadily, and you may hear a chime. If equipped with a message center,
the vehicle will also indicate a failure with the brake system, have the
system serviced by an authorized dealer immediately.
The AdvanceTracsystem automatically enables each time the engine is
started. All features of the AdvanceTracsystem (TCS and ESC) are
active and monitor the vehicle from start-up. However, the system will
only intervene if the driving situation requires it.

R (Reverse)
With the gearshift lever in R (Reverse), the vehicle will move backward.
Always come to a complete stop before shifting into and out of R
(Reverse).
N (Neutral)
With the gearshift lever in N (Neutral), the vehicle is free to roll; hold
the brake pedal down while in this position. Because of the unique
nature of the hybrid vehicle, the engine will not start in the N (Neutral)
position.
The vehicle does not charge the high voltage battery in the N
(Neutral) position. Do not idle the vehicle in N (Neutral) for
extended periods as this will discharge your high voltage battery.
D (Drive)
The normal driving position for the best fuel economy.
L (Low)
•Provides maximum engine braking.
•The transmission may be shifted into L (Low) at any vehicle speed.
WARNING:When parking, do not use the gearshift in place of
the parking brake. Always set the parking brake fully and make
sure that the gearshift is securely latched in P (Park). Turn off the
ignition whenever you leave your vehicle. Never leave your vehicle
unattended while it is running. If you do not take these precautions,
your vehicle may move unexpectedly and injure someone.
If your vehicle gets stuck in mud or snow
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting between forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.

Note:The default setting for the rear camera delay is off. Press the
“Settings” button found on the navigation screen to set the rear camera
delay feature to on or off. Refer to theNavigation Systemsupplement
for more information.
The camera lens for the camera is located on the trunk. Keep the lens
clean so that the video image remains clear and undistorted. Clean the
lens with a soft, lint-free cloth and non-abrasive cleaner.
Note:If the camera system image is not clear or seems distorted, it may
be covered with water droplets, snow, mud or any other substance. If
this occurs, clean the camera lens before using the reverse camera
system.
WARNING:The camera system is a reverse aid supplement
device that still requires the driver to use it in conjunction with
the rearview mirror and the side mirrors for maximum coverage.
WARNING:Objects that are close to either corner of the
bumper or under the bumper, might not be seen on the screen
due to the limited coverage of the camera system.
WARNING:Backup as slow as possible since higher speeds
might limit your reaction time to stop the vehicle.
WARNING:Do not use the camera system with the trunk open.
If the back end of the vehicle is hit or damaged, then check with your
authorized dealer to have your rear video system checked for proper
coverage and operation.
Night time and dark area use
At night time or in dark areas, the camera system relies on the reverse
lamp lighting to produce an image. Therefore it is necessary that both
reverse lamps are operating in order to get a clear image in the dark. If
either of the lamps are not operating, stop using the camera system, at
least in the dark, until the lamp(s) are replaced and functioning.
Servicing
•If the image comes on while the vehicle is not in R (Reverse), have
the system inspected by your authorized dealer.

Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Note:The tire pressure monitoring system (TPMS) indicator light will
illuminate when the spare tire is in use. To restore the full functionality
of the monitoring system, all road wheels equipped with tire pressure
monitoring sensors must be mounted on the vehicle.
Have a flat serviced by an authorized dealer in order to prevent damage
to the TPMS sensors, refer toTire pressure monitoring system
(TPMS)in theTires, Wheels and Loadingchapter. Replace the spare
tire with a road tire as soon as possible. During repairing or replacing of
the flat tire, have the authorized dealer inspect the TPMS sensor for
damage.
WARNING:The use of tire sealants may damage your tire
pressure monitoring system (TPMS) and should not be used.
However, if you must use a sealant, the TPMS sensor and valve stem
on the wheel must be replaced by an authorized Ford dealer.
WARNING:Refer toTire pressure monitoring system (TPMS)
in theTires, Wheels and Loadingchapter for important
information. If the tire pressure monitor sensor becomes damaged, it
will no longer function.
