GENERAL INFORMATION
See the following sections for directions
on how to properly use safety restraints
for children.
WARNING: Always make sure your
child is secured properly in a device that
is appropriate for their height, age and
weight. Child safety restraints must be
bought separately from your vehicle.
Failure to follow these instructions and
guidelines may result in an increased risk
of serious injury or death to your child.
WARNING: All children are shaped
differently. The National Highway Traffic
Safety Administration and other safety
organizations, base their
recommendations for child restraints on
probable child height, age and weight
thresholds, or on the minimum
requirements of the law. We recommend
that you check with a NHTSA Certified
Child Passenger Safety Technician
(CPST) to make sure that you properly
install the child restraint in your vehicle
and that you consult your pediatrician to
make sure you have a child restraint
appropriate for your child. To locate a
child restraint fitting station and CPST,
contact NHTSA toll free at
1-888-327-4236 or go to
www.nhtsa.dot.gov. In Canada, contact
Transport Canada toll free at
1-800-333-0371 or go to www.tc.gc.ca
to find a Child Car Seat Clinic in your
area. Failure to properly restrain children
in child restraints made especially for
their height, age and weight, may result
in an increased risk of serious injury or
death to your child.
WARNING: On hot days, the
temperature inside the vehicle can rise
very quickly. Exposure of people or
animals to these high temperatures for
even a short time can cause death or
serious heat related injuries, including
brain damage. Small children are
particularly at risk.

Child Safety
Recommendations for Safety Restraints for Children
Recommended Restraint
Type Child Size, Height, Weight, or Age Child
Use a child restraint
(sometimes called an
infant carrier, convertible
seat, or toddler seat). Children weighing 40 lb (18 kg) or less
(generally age four or younger). Infants or
toddlers
Use a belt-positioning
booster seat. Children who have outgrown or no longer
properly fit in a child restraint (generally
children who are less than 57 in (1.45 m)
tall, are greater than age four and less
than age 12, and between 40 lb (18 kg)
and 80 lb (36 kg) and upward to 100 lb
(45 kg) if recommended by your child
restraint manufacturer). Small children
Use a vehicle seatbelt
having the lap belt snug
and low across the hips,
shoulder belt centered
across the shoulder and
chest, and seat backrest
upright. Children who have outgrown or no longer
properly fit in a belt-positioning booster
seat (generally children who are at least
57 in (1.45 m) tall or greater than 80 lb
(36 kg) or 100 lb (45 kg) if recommended
by child restraint manufacturer). Larger children
• You are required by law to properly use
child restraints for infants and toddlers
in the United States and Canada.
• Many states and provinces require that
small children use approved booster
seats until they reach age eight, a
height of 57 in (1.45 m) tall, or 80 lb
(36 kg). Check your local and state or
provincial laws for specific
requirements about the safety of
children in your vehicle.• When possible, always properly
restrain children 12 years of age and
under in a rear seating position of your
vehicle. Accident statistics suggest that
children are safer when properly
restrained in the rear seating positions
than in a front seating position.
• When installing a rear facing child
restraint, adjust the vehicle seats to
avoid interference between the child
restraint and the vehicle seat in front
of the child restraint.

Child Safety
7. Try to pull the belt out of the retractor
to make sure the retractor is in the
automatic locking mode. You should
not be able to pull more belt out. If the
retractor is not locked, unbuckle the
belt and repeat Steps 5 and 6.
E142533
8. Remove remaining slack from the belt.
Force the seat down with extra weight,
for example, by pressing down or
kneeling on the child restraint while
pulling up on the shoulder belt in order
to force slack from the belt. This is
necessary to remove the remaining
slack that exists once you add the extra
weight of the child to the child restraint.
It also helps to achieve the proper
snugness of the child restraint to your
vehicle. Sometimes, a slight lean
toward the buckle helps to remove
remaining slack from the belt.
9. If the child restraint has a tether strap,
attach it.
E142534
10. Before placing the child in the seat,
forcibly move the seat forward and
back to make sure the seat is securely
held in place.
To check this, grab the seat at the belt path
and attempt to move it side to side and
forward and back. There should be no
more than 1 in (2.5 cm) of movement.
We recommend checking with a NHTSA
Certified Child Passenger Safety
Technician to make certain the child
restraint is properly installed. In Canada,
check with Transport Canada for referral
to a Child Car Seat Clinic.
Using Cinch Tongue Seatbelts
WARNING: Do not place a
rearward facing child restraint in front of
an active airbag. Failure to follow this
instruction could result in personal injury
or death.
28
Child Safety
E14259742597
If the booster seat slides on the vehicle
seat upon which it is being used, 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.
CHILD RESTRAINT
POSITIONING
WARNING: Airbags can kill or injure
a child in a child seat. Never place a
rear-facing child seat in front of an active
airbag. If you must use a forward-facing
child seat in the front seat, move the
vehicle seat upon which the child seat is
installed all the way back. When
possible, all children age 12 and under
should be properly restrained in a rear
seating position. If all children cannot be
seated and restrained properly in a rear
seating position, properly restrain the
largest child in the front seat.
WARNING: Always carefully follow
the instructions and warnings provided
by the manufacturer of any child
restraint to determine if the restraint
device is appropriate for your child's size,
height, weight, or age. Follow the child
restraint manufacturer's instructions and
warnings provided for installation and
use in conjunction with the instructions
and warnings provided by your vehicle
manufacturer. A safety seat that is
improperly installed or utilized, is
inappropriate for your child's height, age,
or weight or does not properly fit the
child may increase the risk of serious
injury or death.
WARNING: Never let a passenger
hold a child on his or her lap while your
vehicle is moving. The passenger cannot
protect the child from injury in a crash,
which may result in serious injury or
death.
WARNING: Never use pillows,
books, or towels to boost a child. They
can slide around and increase the
likelihood of injury or death in a crash.
34
Child Safety
WARNING: Always restrain an
unoccupied child seat or booster seat.
These objects may become projectiles
in a crash or sudden stop, which may
increase the risk of serious injury.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 crash.
WARNING: To avoid risk of injury,
do not leave children or pets unattended
in your vehicle.

CHILD SAFETY LOCKS (IF
EQUIPPED)
When these locks are set, the rear doors
cannot be opened from the inside.

Child Safety
When the engine idle shutdown process
has started:
• A chime sounds and a message
appears in the information display
showing a timer counting down from
30 seconds.
• You can reset the timer by pressing the
brake pedal, accelerator pedal, or by
shifting into another gear.
• If you do not intervene within 30
seconds, the engine shuts down and a
message appears in the information
display alerting you that the engine has
shut down.
• Shortly after the engine has shut down,
the electrical system simulates a key
off and even though the ignition is still
on, the electrical system simulates a
normal accessory delay period before
shutting down.
• You must switch the ignition off to
reset the system before restarting your
vehicle.
The engine idle shutdown timer does not
start if:
• The engine is operating in battery
charge protect or power take-off mode.
• The exhaust emission control device is
regenerating.
ENGINE BLOCK HEATER (IF
EQUIPPED)
WARNING: Failure to follow engine
block heater instructions could result in
property damage or serious personal
injury.
WARNING: Do not use your heater
with ungrounded electrical systems or
two-pronged adapters. There is a risk of
electrical shock.
WARNING: Do not fully close the
hood, or allow it to drop under its own
weight when using the engine block
heater. This could damage the power
cable and may cause an electrical short
resulting in fire, injury and property
damage.
Note:The heater is most effective when
outdoor temperatures are below 0°F
(-18°C).
The heater acts as a starting aid by
warming the engine coolant. This allows
the climate control system to respond
quickly. The equipment includes a heater
element (installed in the engine block) and
a wire harness. You can connect the
system to a grounded 120-volt AC
electrical source.
We recommend that you do the following
for a safe and correct operation:
• Use a 16-gauge outdoor extension cord
that is product certified by
Underwriter’s Laboratory (UL) or
Canadian Standards Association
(CSA). This extension cord must be
suitable for use outdoors, in cold
temperatures, and be clearly marked
Suitable for Use with Outdoor
Appliances. Do not use an indoor
extension cord outdoors. This could
result in an electric shock or become a
fire hazard.
• Use as short an extension cord as
possible.
• Do not use multiple extension cords.
• Make sure that when in operation, the
extension cord plug and heater cord
plug connections are free and clear of
water. This could cause an electric
shock or fire.
• Make sure your vehicle is parked in a
clean area, clear of combustibles.
103
Starting and Stopping the Engine
Keep a record for at least one month and
record the type of driving (city or highway).
This provides an accurate estimate of your
vehicle's fuel economy under current
driving conditions. Keeping records during
summer and winter will show how
temperature impacts fuel economy.
Conditions
• Heavily loading your vehicle reduces
fuel economy.
• Carrying unnecessary weight in your
vehicle may reduce fuel economy.
• Adding certain accessories to your
vehicle such as bug deflectors, rollbars
or light bars, running boards and ski
racks may reduce fuel economy.
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures.
• Fuel economy may decrease when
driving short distances.
• You will get better fuel economy when
driving on flat terrain than when driving
on hilly terrain.FUEL TANK SELECTOR
SWITCH
(IF EQUIPPED)
E205996
Your vehicle may have two fuel tanks. The
fuel in each fuel tank is independently
used. Use the switch on the instrument
panel to select the left-hand or right-hand
fuel tank. The fuel gauge indicates the
remaining fuel in the selected fuel tank.
See Gauges (page 63).
