•To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. For additional information, refer toAutomatic
transmission operationin theDrivingchapter.
•Anticipate stops and brake gradually.
•Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to yourscheduled maintenance
informationfor more information.
Trailer towing tips
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
•Practice turning, stopping and backing-up before starting on a trip to
get the feel of the vehicle-trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
•Allow more distance for stopping with a trailer attached.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
Launching or retrieving a boat
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.
When backing down a ramp during boat launching or retrieval:
•do not allow the static water level to rise above the bottom edge of
the rear bumper.
•do not allow waves to break higher than 6 in. (15 cm) above the
bottom edge of the rear bumper.

Starting the engine
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 as soon as the
engine begins cranking. Your vehicle has a computer assisted cranking
system that assists in starting the engine. After releasing the key from
the 4 (start) position, the engine may continue cranking for up to
10 seconds or until the vehicle starts.
Note:Cranking may be stopped at any time by turning the key to the off
position.
3. After idling for a few seconds, release the parking brake, apply the
brake, shift into gear and drive.
Note:If the engine does not start on the first try, turn the key to the off
position, wait 10 seconds and try Step 2 again. If the engine still fails to
start, press the accelerator to the floor and try Step 2 again, keeping the
accelerator on the floor until the engine begins to accelerate above
cranking speeds; this will allow the engine to crank with the fuel shut off
in case the engine is flooded with fuel.
Cold weather starting (flexible fuel vehicles only)
The starting characteristics of all grades of E
85ethanol make it
unsuitable for use when ambient temperatures fall below 0°F (-18°C).
Consult your fuel distributor for the availability of winter grade ethanol.
As the outside temperature approaches freezing, ethanol fuel distributors
should supply winter grade ethanol (same as with unleaded gasoline). If
summer grade ethanol is used in cold weather conditions, 0°F to 32°F
(-18°C to 0°C), you may experience increased cranking times, rough idle
or hesitation until the engine has warmed up.
You may experience a decrease in peak performance when the engine is
cold when operating on E
85ethanol.
Do not crank the engine for more than 10 seconds at a time as starter
damage may occur. If the engine fails to start, turn the key to off and
wait 30 seconds before trying again.

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.
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 can be started and is
free to roll. Hold the brake pedal down while in this position.
D (Drive) with Overdrive
The normal driving position for the best fuel economy. Transmission
operates in gears one through six.
D (Drive) with Grade Assist
Pressing the transmission control
switch on the side of the gearshift
lever activates grade assist and
cancels overdrive.
•Provides additional grade
(engine) braking and extends
lower gear operation on uphill
climbs for hilly terrain or
mountainous areas.
•Provides additional engine
braking through the automatic
transmission shift strategy which
reacts to vehicle inputs (vehicle
acceleration, accelerator pedal,
brake pedal and vehicle speed).
•Allows the transmission to select
gears that will provide the desired engine braking based on the vehicle
inputs mentioned above. This will increase engine RPM during engine
braking.

•The grade assist lamp in the
instrument cluster is illuminated.
Grade assist is designed to aid the
driver with optimal gear selection in
hilly terrain or mountainous areas
but is not intended for normal operation. It is recommended that you
return to O/D (overdrive mode) on flat terrain to provide the best fuel
economy and transmission function.
To return to normal D (Drive) position (with O/D), press the
transmission control switch again.
•The grade assist lamp in the instrument cluster will not be illuminated.
•The transmission will operate in gears one through six.
O/D (overdrive mode) is automatically returned each time the engine is
turned off.
L (Low)
•Provides maximum engine braking.
•Will downshift to the lowest available gear for the current vehicle
speed; allows for first gear when vehicle reaches slower speeds.
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.
Driving

2010 Mariner(mrn)
Owners Guide, 2nd Printing
USA(fus)

Note:If the system cannot be turned off, refer toMyKey™in theLocks
and Securitychapter for more information.
Keep the RSS sensors (located on the rear bumper/fascia) free
from snow, ice and large accumulations of dirt (do not clean the
sensors with sharp objects). If the sensors are covered, it will
affect the accuracy of the RSS.
If your vehicle sustains damage to the rear bumper/fascia, leaving
it misaligned or bent, the sensing zone may be altered causing
inaccurate measurement of obstacles or false alarms.
REARVIEW CAMERA SYSTEM (IF EQUIPPED)
The rearview camera system located
on the liftgate provides a video
image, which appears in the
rearview mirror or on the navigation
screen (if equipped), of the area
behind the vehicle. It adds
assistance to the driver while
reversing or reverse parking the
vehicle.
To use the camera, place the transmission in R (Reverse); an image will
display on the left portion of the rearview mirror or on the navigation
screen (if equipped). The area displayed on the screen may vary
according to the vehicle orientation and/or road condition.
•(1) Rear bumper
•(2) Red zone
•(3) Yellow zone
•(4) Green zone
•(5) Centerline of vehicle
Always use caution while backing.
Objects in the red zone are closest
to your vehicle and objects in the
green zone are further away. Objects
are getting closer to your vehicle as they move from the green zone to
the yellow or red zones.
Use the side mirrors and rearview mirror to get better coverage on both
sides and rear of the vehicle.

Image delay if displayed through the rearview mirror:
When shifting out of R (Reverse) and into any other gear, the image in
the rearview mirror will remain on for a few seconds before it shuts off
to assist in parking or trailer hookup.
Image delay if displayed through the Navigation screen:
After shifting out of R (Reverse) and into any gear other than P (Park),
the image in the navigation screen will remain until the vehicle speed
reaches 5 mph (8 km/h), only if the rear camera delay feature is on, or
until any navigation radio button is pressed.
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.
•If the image is not clear, then check if there is anything covering the
lens such as dirt, mud, ice, snow, etc. If the image is still not clear
after cleaning, have your camera inspected by your authorized dealer.
ACTIVE PARK ASSIST (APA) (IF EQUIPPED)
Active park assist (APA) will detect an available parallel parking space
and automatically steer the vehicle into the space (hands-free) while you
control the accelerator, gearshift and brakes. The system will visually
and/or audibly instruct the driver to park the vehicle.
WARNING:This system is designed to be a supplementary park
aid. It may not work in all conditions and is not intended to
replace the driver’s attention and judgment. The driver is responsible
for avoiding hazards and maintaining a safe distance and speed, even
when the APA is in use.
Conditions in which the systems may not work:
•Something passes between the front bumper and the space such as a
pedestrian or cyclist
•The edge of the vehicle is high from the ground such as a bus, tow
truck or flat bed truck
Automatic search for parking space
