2011 Mercury Mariner warning light

•Roll Stability Control™ (RSC), which functions to help avoid a
vehicle roll-over
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 AdvanceTracwith RSCsystem. In addition, installing any
stereo loudspeakers may interfere with and adversely affect the
AdvanceTracwith RSCsystem. 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 AdvanceTracwith RSCsensors. Reducing the effectiveness
of the AdvanceTracwith RSCsystem 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 AdvanceTracwith RSCsystem 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 AdvanceTracwith RSCsystem
activates, SLOW DOWN.
WARNING:If a failure has been detected within the
AdvanceTracwith RSCsystem, the stability control light will
illuminate steadily. Have the system serviced by an authorized dealer
immediately. Operating your vehicle with AdvanceTracwith RSC
disabled could lead to an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death.
The AdvanceTracwith RSCsystem automatically enables each time
the engine is started. All features of the AdvanceTracwith RSCsystem
(TCS, ESC, and RSC) are active and monitor the vehicle from start-up.
However, the system will only intervene if the driving situation requires
it.

Trailer sway control (if equipped)
Your vehicle may be equipped with trailer sway control (TSC). When
properly equipped, trailer sway control will use the sensors of the
vehicle’s AdvanceTracwith RSCsystem to detect and attempt to
mitigate trailer sway by applying brake force at individual wheels and, if
necessary, by reducing engine power. No driver action is required.
WARNING:Trailer sway control does not prevent a trailer from
swaying, it mitigates the sway from increasing once it has
occurred. TSC cannot stop all trailers from swaying. If you are
experiencing trailer sway, it is likely that the trailer is improperly
loaded for the correct tongue weight or the speed of the vehicle and
trailer is too high. Pull the vehicle-trailer over to a safe location to
check the trailer weight distribution and tongue load and reduce speed
to a safe level while towing. If trailer sway is experienced, SLOW
DOWN. Always use caution when towing a trailer and follow the
tongue weight recommendations. Refer to theTrailer towingsection
in theTires Wheels and Loadingchapter of this owner’s guide for
more information on towing a trailer with your vehicle.
During trailer sway control events, the stability control light in the
instrument cluster will flash momentarily. In some cases, when trailer
sway is detected, the vehicle speed is too high and may be at or above a
speed at which trailer sway will grow continuously. This may cause the
system to activate multiple times, and you may experience a slight
deceleration of the vehicle.
Disabling trailer sway control
Trailer sway control can be disabled during any key cycle. Pressing and
holding the stability control button for more than five seconds will
disable the trailer sway control feature and the stability control light will
flash momentarily and then illuminate solid for that ignition cycle. Trailer
sway control can be re-enabled by momentarily pressing the stability
control button. Trailer sway control will also be re-enabled at each new
key cycle.
WARNING:Turning off trailer sway control increases the risk of
loss of vehicle control, serious injury, or death. Ford does not
recommend disabling this feature except in situations where speed
reduction may be detrimental (e.g., hill climbing), the driver has
significant trailer towing experience, and can control trailer sway and
maintain safe operation.

WARNING:Do not drive your vehicle until you verify that the
brakelamps are working.
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Turn the ignition to the off
position and remove the key whenever you leave your vehicle.
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.
AUTOMATIC TRANSMISSION OPERATION
Automatic transmission adaptive learning
Your transmission is equipped with an adaptive learning strategy found in
the vehicle computer. This feature is designed to increase durability and
provide consistent shift feel over the life of the vehicle. A new vehicle or
transmission may have firm and/or soft shifts. This operation is
considered normal and will not affect function or durability of the
transmission. Over time, the adaptive learning process will fully update
transmission operation. Additionally, whenever the battery is
disconnected or a new battery installed, the strategy must be relearned.
Understanding the gearshift positions of the 6–speed automatic
transmission
Your vehicle has been designed to improve fuel economy by reducing
fuel usage while coasting or decelerating. When you take your foot off
the accelerator pedal and the vehicle begins to slow down, the torque
converter clutch locks up and aggressively shuts off fuel flow to the
engine while decelerating. This fuel economy benefit may be perceived
as a light to medium braking sensation when removing your foot from
the accelerator pedal.

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.
REVERSE SENSING SYSTEM (IF EQUIPPED)
The reverse sensing system (RSS) sounds a tone to warn the driver of
obstacles near the rear bumper when R (Reverse) is selected and the
vehicle is moving at speeds less than 3 mph (5 km/h). The system is not
effective at speeds above 3 mph (5 km/h) and may not detect certain
angular or moving objects.
WARNING:To help avoid personal injury, please read and
understand the limitations of the reverse sensing system as
contained in this section. Reverse sensing is only an aid for some
(generally large and fixed) objects when moving in reverse on a flat
surface at “parking speeds”. Inclement weather may also affect the
function of the RSS; this may include reduced performance or a false
activation.
WARNING:To help avoid personal injury, always use caution
when in reverse and when using the RSS.
WARNING:This system is not designed to prevent contact with
small or moving objects. The system is designed to provide a
warning to assist the driver in detecting large stationary objects to
avoid damaging the vehicle. The system may not detect smaller
objects, particularly those close to the ground.
WARNING:Certain add-on devices such as large trailer hitches,
bike or surfboard racks and any device that may block the
normal detection zone of the RSS system may create false beeps.

Note:The default setting for the camera delay is off. Press the
“Settings” button found on the navigation screen (if equipped) to set the
camera delay feature to on or off.
When towing, the camera will only see what is being towed behind the
vehicle; this might not provide adequate coverage as it usually provides
in normal operation and some objects might not be seen.
The lens for the camera is located on the liftgate. Keep the lens clean so
the video image remains clear and undistorted. Clean the lens with a
soft, lint-free cloth and non-abrasive cleaner.
Note:If the camera 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.
WARNING:The camera 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.
WARNING:Backup as slow as possible since higher speeds
might limit your reaction time to stop the vehicle.
WARNING:Do not use the camera with the liftgate open.
If the back end of the vehicle is hit or damaged, then check with your
authorized dealer to have your camera checked for proper coverage and
operation.
Night time and dark area use
At night time or in dark areas, the camera 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, 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 camera inspected by your authorized dealer.

sideways out of control or roll over. Remember, your safety and the
safety of others should be your primary concern.
WARNING:Vehicles with a higher center of gravity such as
utility and four-wheel drive vehicles handle differently than
vehicles with a lower center of gravity. Utility and four-wheel drive
vehicles arenotdesigned for cornering at speeds as high as passenger
cars any more than low-slung sports cars are designed to perform
satisfactorily under off-road conditions. Avoid sharp turns, excessive
speed and abrupt maneuvers in these vehicles. Failure to drive
cautiously could result in an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death.
If your vehicle gets stuck
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 few minutes or damage
to the transmission and tires may occur or the engine may
overheat.
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Turn the ignition to the off
position and remove the key whenever you leave your vehicle.
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.
WARNING:Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.
Emergency maneuvers
•In an unavoidable emergency situation where a sudden sharp turn
must be made, remember to avoid “over-driving” your vehicle, i.e.,
turn the steering wheel only as rapidly and as far as required to avoid
the emergency. Excessive steering will result in less vehicle control,

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
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.
