2010 Mercury Mariner warning

method eliminates the need to use safety belts to attach the child seat,
however the safety belt can still be used to attach the child seat. For
forward-facing child seats, the top tether strap must also be attached to
the proper top tether anchor, if a top tether strap has been provided
with your child seat. Ford Motor Company recommends the use of a
child safety seat having a top tether strap. SeeAttaching child safety
seats with tether strapsandRecommendations for attaching safety
restraints for childrenin this chapter for more information.
Your vehicle has LATCH lower anchors for child seat installation at the
seating positions marked with the child seat symbol.
The LATCH anchors are located at
the rear section of the rear seat
between the cushion and seatback.
Follow the child seat manufacturer’s
instructions to properly install a
child seat with LATCH attachments.
Follow the instructions on attaching
child safety seats with tether straps.
Refer toAttaching child safety
seats with tether strapslater in this
chapter.
Attach LATCH lower attachments of
the child seat only to the anchors
shown.
WARNING:Never attach
two child safety seats to the
same anchor. In a crash, one
anchor may not be strong enough
to hold two child safety seat
attachments and may break,
causing serious injury or death.

WARNING:Depending on where you secure a child restraint,
and depending on the child restraint design, you may block
access to certain safety belt buckle assemblies and/or LATCH lower
anchors, rendering those features potentially unusable. To avoid risk of
injury, occupants should only use seating positions where they are able
to be properly restrained.
Use of inboard lower anchors from the outboard seating positions
(center seating use)
The lower anchors at the center of the second row rear seat are spaced
400 mm (16 inches) apart. The standardized spacing for LATCH lower
anchors is 280 mm (11 inches) center to center. A child seat with rigid
LATCH attachments cannot be installed at the center seating position.
LATCH compatible child seats (with attachments on belt webbing) can
only be used at this seating position provided that the child seat
manufacturer’s instructions permit use with the anchor spacing stated.
Do not attach a child seat to any lower anchor if an adjacent child seat is
attached to that anchor.
WARNING:The standardized spacing for LATCH lower anchors
is 280 mm (11 inches) center to center. Do not use LATCH
lower anchors for the center seating position unless the child seat
manufacturer’s instructions permit and specify using anchors spaced at
least as far apart as those of this vehicle.
If you install a child seat with rigid LATCH attachments, and have
attached the top tether strap to the proper top tether anchor, do not
tighten the tether strap enough to lift the child seat off the vehicle seat
cushion when the child is seated in it. Keep the tether strap just snug
without lifting the front of the child seat. Keeping the child seat just
touching the vehicle seat gives the best protection in a severe crash.
Each time you use the safety seat, check that the seat is properly
attached to the lower anchors and tether anchor, if applicable. Tug the
child seat from side to side and forward and back where it is secured to
the vehicle. The seat should move less than one inch when you do this
for a proper installation.
If the safety seat is not anchored properly, the risk of a child being
injured in a crash greatly increases.

If the booster seat slides on the vehicle seat, placing a rubberized mesh
sold as shelf or carpet liner under the booster seat may improve this
condition. Do not introduce any item thicker than this under the booster
seat. Check with the booster seat manufacturer’s instructions.
The importance of shoulder belts
Using a booster without a shoulder belt increases the risk of a child’s
head hitting a hard surface in a collision. For this reason, you should
never use a booster seat with a lap belt only. It is generally best to use a
booster seat with lap/shoulder belts in the back seat.
Move a child to a different seating location if the shoulder belt does not
stay positioned on the shoulder during use.
Follow all instructions provided by the manufacturer of the booster seat.
WARNING:Never place, or allow a child to place, the shoulder
belt under a child’s arm or behind the back because it reduces
the protection for the upper part of the body and may increase the risk
of injury or death in a collision.
Child restraint and safety belt maintenance
Inspect the vehicle safety belts and child safety seat systems periodically
to make sure they work properly and are not damaged. Inspect the
vehicle and child seat safety belts to make sure there are no nicks, tears
or cuts. Replace if necessary. All vehicle safety belt assemblies, including
retractors, buckles, front safety belt buckle assemblies, buckle support
assemblies (slide bar-if equipped), shoulder belt height adjusters (if
equipped), shoulder belt guide on seatback (if equipped), child safety
seat LATCH and tether anchors, and attaching hardware, should be
inspected after a collision. Refer to the child restraint manufacturer’s
instructions for additional inspection and maintenance information
specific to the child restraint. Ford Motor Company recommends that all
safety belt assemblies in use in vehicles involved in a collision be
replaced. However, if the collision was minor and an authorized dealer
finds that the belts do not show damage and continue to operate
properly, they do not need to be replaced. Safety belt assemblies not in
use during a collision should also be inspected and replaced if either
damage or improper operation is noted.
For proper care of soiled safety belts, refer toInteriorin theCleaning
chapter.

NOTICE TO UTILITY VEHICLE AND TRUCK OWNERS
Utility vehicles and trucks handle
differently than passenger cars in
the various driving conditions that
are encountered on streets,
highways and off-road. Utility
vehicles and trucks are not designed
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.
WARNING:Utility vehicles have a significantly higher rollover
rate than other types of vehicles. To reduce the risk of serious
injury or death from a rollover or other crash you must:
•Avoid sharp turns and abrupt maneuvers;
•Drive at safe speeds for the conditions;
•Keep tires properly inflated;
•Never overload or improperly load your vehicle; and
•Make sure every passenger is properly restrained.
WARNING:In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a seat belt.
All occupants must wear seat belts and children/infants must use
appropriate restraints to minimize the risk of injury or ejection.
Study your owner’s guide and any supplements for specific information
about equipment features, instructions for safe driving and additional
precautions to reduce the risk of an accident or serious injury.
VEHICLE CHARACTERISTICS
4WD and AWD Systems (if equipped)
A vehicle equipped with AWD or 4WD (when selected) has the ability to
use all four wheels to power itself. This increases traction which may
enable you to safely drive over terrain and road conditions that a
conventional two-wheel drive vehicle cannot.
Tires, Wheels and Loading

Power is supplied to all four wheels through a transfer case or power
transfer unit. 4WD vehicles allow you to select different drive modes as
necessary. Information on transfer case operation and shifting procedures
can be found in theDrivingchapter. Information on transfer case
maintenance can be found in theMaintenance and Specifications
chapter. You should become thoroughly familiar with this information
before you operate your vehicle.
On some 4WD models, the initial shift from two-wheel drive to 4WD
while the vehicle is moving can cause a momentary clunk and ratcheting
sound. These sounds are normal as the front drivetrain comes up to
speed and is not cause for concern.
WARNING:Do not become overconfident in the ability of 4WD
and AWD vehicles. Although a 4WD or AWD vehicle may
accelerate better than two-wheel drive vehicle in low traction
situations, it won’t stop any faster than two-wheel drive vehicles.
Always drive at a safe speed.
How your vehicle differs from other vehicles
SUV and trucks can differ from
some other vehicles in a few
noticeable ways. Your vehicle may
be:
•Higher – to allow higher load
carrying capacity and to allow it
to travel over rough terrain
without getting hung up or
damaging underbody components.
•Shorter – to give it the capability
to approach inclines and drive
over the crest of a hill without
getting hung up or damaging
underbody components. All other
things held equal, a shorter
wheelbase may make your vehicle
quicker to respond to steering inputs than a vehicle with a longer
wheelbase.

Treadwear
The treadwear grade is a comparative rating based on the wear rate of
the tire when tested under controlled conditions on a specified
government test course. For example, a tire graded 150 would wear one
and one-half (1
12) times as well on the government course as a tire
graded 100. The relative performance of tires depends upon the actual
conditions of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices, and
differences in road characteristics and climate.
Traction AA A B C
The traction grades, from highest to lowest are AA, A, B, and C. The
grades represent the tire’s ability to stop on wet pavement as measured
under controlled conditions on specified government test surfaces of
asphalt and concrete. A tire marked C may have poor traction
performance.
WARNING:The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not include
acceleration, cornering, hydroplaning or peak traction characteristics.
Temperature A B C
The temperature grades are A (the highest), B and C, representing the
tire’s resistance to the generation of heat and its ability to dissipate heat
when tested under controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a level of performance
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 139. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
WARNING:The temperature grade for this tire is established
for a tire that is properly inflated and not overloaded. Excessive
speed, underinflation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.

INFLATING YOUR TIRES
Safe operation of your vehicle requires that your tires are properly
inflated. Remember that a tire can lose up to half of its air pressure
without appearing flat.
Every day before you drive, check your tires. If one looks lower than the
others, use a tire gauge to check pressure of all tires and adjust if
required.
At least once a month and before long trips, inspect each tire and check
the tire pressure with a tire gauge (including spare, if equipped). Inflate
all tires to the inflation pressure recommended by Ford Motor Company.
You are strongly urged to buy a reliable tire pressure gauge, as automatic
service station gauges may be inaccurate. Ford recommends the use of a
digital or dial-type tire pressure gauge rather than a stick-type tire
pressure gauge.
Use the recommended cold inflation pressure for optimum tire
performance and wear. Under-inflation or over-inflation may cause
uneven treadwear patterns.
WARNING:Under-inflation is the most common cause of tire
failures and may result in severe tire cracking, tread separation
orblowout, with unexpected loss of vehicle control and increased risk
of injury. Under-inflation increases sidewall flexing and rolling
resistance, resulting in heat buildup and internal damage to the tire. It
also may result in unnecessary tire stress, irregular wear, loss of
vehicle control and accidents. A tire can lose up to half of its air
pressure and not appear to be flat!
Always inflate your tires to the Ford recommended inflation pressure
even if it is less than the maximum inflation pressure information found
on the tire. The Ford recommended tire inflation pressure is found on
the Safety Compliance Certification Label or Tire Label which is located
on the B-Pillar or the edge of the driver’s door. Failure to follow the tire
pressure recommendations can cause uneven treadwear patterns and
adversely affect the way your vehicle handles.
Maximum Permissible Inflation Pressureis the tire manufacturer’s
maximum permissible pressure and/or the pressure at which the
maximum load can be carried by the tire. This pressure is normally
higher than the manufacturer’s recommended cold inflation pressure
which can be found on the Safety Compliance Certification Label or Tire
Label which is located on the B-Pillar or the edge of the driver’s door.
