Child RestraintsOlder ChildrenOlder children who have outgrown booster seats should
wear the vehicle’s safety belts.The manufacturer’s instructions that come with the
booster seat, state the weight and height limitations for
that booster. Use a booster seat with a lap-shoulder
belt until the child passes the below fit test:
•
Sit all the way back on the seat. Do the knees bend
at the seat edge? If yes, continue. If no, return to
the booster seat.
•
Buckle the lap-shoulder belt. Does the shoulder belt
rest on the shoulder? If yes, continue. If no, try
using the rear safety belt comfort guide. See “Rear
Safety Belt Comfort Guides” underLap-Shoulder
Belt on page 2-25for more information. If the
shoulder belt still does not rest on the shoulder,
then return to the booster seat.
•
Does the lap belt fit low and snug on the hips,
touching the thighs? If yes, continue. If no, return to
the booster seat.
•
Can proper safety belt fit be maintained for
length of trip? If yes, continue. If no, return to the
booster seat.
If you have the choice, a child should sit in a position
with a lap-shoulder belt and get the additional restraint a
shoulder belt can provide.

Q:
What are the different types of add-on child
restraints?
A:
Add-on child restraints, which are purchased by the
vehicle’s owner, are available in four basic types.
Selection of a particular restraint should take into
consideration not only the child’s weight, height, and
age but also whether or not the restraint will be
compatible with the motor vehicle in which it will
be used.
For most basic types of child restraints, there are
many different models available. When purchasing a
child restraint, be sure it is designed to be used
in a motor vehicle. If it is, the restraint will have a
label saying that it meets federal motor vehicle
safety standards.
The restraint manufacturer’s instructions that come
with the restraint state the weight and height
limitations for a particular child restraint. In addition,
there are many kinds of restraints available for
children with special needs.
{
WARNING:
To reduce the risk of neck and head injury during
a crash, infants need complete support. This is
because an infant’s neck is not fully developed
and its head weighs so much compared with
the rest of its body. In a crash, an infant in a
rear-facing child restraint settles into the restraint,
so the crash forces can be distributed across the
strongest part of an infant’s body, the back and
shoulders. Infants should always be secured in
rear-facing child restraints.

Passenger Sensing SystemThe vehicle has a passenger sensing system for the
right front passenger position. The passenger airbag
status indicator will be visible on the instrument
panel when the vehicle is started.
The words ON and OFF, or the symbol for on and off,
will be visible during the system check. If you are
using remote start to start the vehicle from a distance, if
equipped, you may not see the system check. When
the system check is complete, either the word ON or the
word OFF, or the symbol for on or off, will be visible.
SeePassenger Airbag Status Indicator on page 4-25.The passenger sensing system will turn off the right
front passenger frontal airbag under certain conditions.
The driver airbag, seat-mounted side impact airbags,
and roof-rail airbags are not affected by the passenger
sensing system.
The passenger sensing system works with sensors that
are part of the right front passenger seat. The sensors
are designed to detect the presence of a properly-seated
occupant and determine if the right front passenger
frontal airbag should be enabled (may inflate) or not.
According to accident statistics, children are safer when
properly secured in a rear seat in the correct child
restraint for their weight and size.
We recommend that children be secured in a rear seat,
including: an infant or a child riding in a rear-facing
child restraint; a child riding in a forward-facing child
seat; an older child riding in a booster seat; and children,
who are large enough, using safety belts.
A label on the sun visor says, “Never put a rear-facing
child seat in the front.” This is because the risk to
the rear-facing child is so great, if the airbag deploys. United States

{
WARNING:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front passenger
airbag inflates. This is because the back of the
rear-facing child restraint would be very close to the
inflating airbag. A child in a forward-facing child
restraint can be seriously injured or killed if the right
front passenger airbag inflates and the passenger
seat is in a forward position.
Even if the passenger sensing system has turned
off the right front passenger frontal airbag, no
system is fail-safe. No one can guarantee that
an airbag will not deploy under some unusual
circumstance, even though the airbag is turned off.
Secure rear-facing child restraints in a rear
seat, even if the airbag is off. If you secure a
forward-facing child restraint in the right front seat,
always move the front passenger seat as far back
as it will go. It is better to secure the child restraint in
a rear seat.The passenger sensing system is designed to turn off
the right front passenger frontal airbag if:
•
The right front passenger seat is unoccupied.
•
The system determines that an infant is present in
a child restraint.
•
A right front passenger takes his/her weight off of
the seat for a period of time.
•
Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned off the
right front passenger frontal airbag, the off indicator
will light and stay lit to remind you that the airbag is off.
SeePassenger Airbag Status Indicator on page 4-25.

Leaving the Vehicle With the Engine
Running
{
WARNING:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly if
the shift lever is not fully in P (Park) with the parking
brake firmly set. And, if you leave the vehicle with
the engine running, it could overheat and even
catch fire. You or others could be injured. Do not
leave the vehicle with the engine running.
If you have to leave the vehicle with the engine running,
be sure your vehicle is in P (Park) and the parking
brake is firmly set before you leave it. SeeParking Brake
on page 3-27for more information.
Torque LockTorque lock is when the weight of the vehicle puts too
much force on the parking pawl in the transmission.
This happens when parking on a hill and shifting the
transmission into P (Park) is not done properly and then it
is difficult to shift out of P (Park). To prevent torque lock,
set the parking brake and then shift into P (Park). To find
out how, see “Shifting Into Park” in this section.
If torque lock does occur, your vehicle may need to be
pushed uphill by another vehicle to relieve the parking
pawl pressure, so you can shift out of P (Park).Shifting Out of ParkAutomatic Transmission Shift LockThe vehicle has an electronic shift lock release system.
The shift lock release is designed to:•
Prevent ignition key removal unless the shift lever is
in P (Park)
•
Prevent movement of the shift lever out of P (Park),
unless the ignition is in ON/RUN and the regular
brake pedal is applied.

BrakingSeeBrake System Warning Light on page 4-27.
Braking action involves perception time and reaction
time. Deciding to push the brake pedal is perception
time. Actually doing it is reaction time.
Average reaction time is about three-fourths of a second.
But that is only an average. It might be less with one
driver and as long as two or three seconds or more with
another. Age, physical condition, alertness, coordination,
and eyesight all play a part. So do alcohol, drugs, and
frustration. But even in three-fourths of a second, a
vehicle moving at 100 km/h (60 mph) travels 20 m
(66 feet). That could be a lot of distance in an emergency,
so keeping enough space between the vehicle and others
is important.
And, of course, actual stopping distances vary greatly
with the surface of the road, whether it is pavement or
gravel; the condition of the road, whether it is wet, dry, or
icy; tire tread; the condition of the brakes; the weight of
the vehicle; and the amount of brake force applied.Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is
a mistake. The brakes might not have time to cool
between hard stops. The brakes will wear out much
faster with a lot of heavy braking. Keeping pace with the
traffic and allowing realistic following distances
eliminates a lot of unnecessary braking. That means
better braking and longer brake life.
If the engine ever stops while the vehicle is being driven,
brake normally but do not pump the brakes. If the brakes
are pumped, the pedal could get harder to push down.
If the engine stops, there will still be some power brake
assist but it will be used when the brake is applied. Once
the power assist is used up, it can take longer to stop and
the brake pedal will be harder to push.
Adding non-dealer/non-retailer accessories can affect
vehicle performance. SeeAccessories and Modifications
on page 6-3.

Rocking Your Vehicle to Get It OutTurn the steering wheel left and right to clear the
area around the front wheels. Turn off any traction
system. Shift back and forth between R (Reverse) and a
forward gear, spinning the wheels as little as possible.
To prevent transmission wear, wait until the wheels stop
spinning before shifting gears. Release the accelerator
pedal while shifting, and press lightly on the accelerator
pedal when the transmission is in gear. Slowly
spinning the wheels in the forward and reverse
directions causes a rocking motion that could free the
vehicle. If that does not get the vehicle out after a
few tries, it might need to be towed out. If the vehicle
does need to be towed out, seeTowing Your Vehicle on
page 5-26.
Loading the VehicleIt is very important to know how much weight your
vehicle can carry. Two labels on your vehicle
show how much weight it may properly carry, the
Tire and Loading Information label and the
Vehicle Certification label.
{
WARNING:
Do not load the vehicle any heavier than the
Gross Vehicle Weight Rating (GVWR), or
either the maximum front or rear Gross Axle
Weight Rating (GAWR). If you do, parts on the
vehicle can break, and it can change the way
your vehicle handles. These could cause you
to lose control and crash. Also, overloading
can shorten the life of the vehicle.

Tire and Loading Information LabelA vehicle specific Tire and Loading Information
label is attached to the vehicle’s center pillar
(B-pillar). With the driver door open, you will find the
label attached below the door lock post (striker).The Tire and Loading Information label lists the
number of occupant seating positions (A), and the
maximum vehicle capacity weight (B) in kilograms
and pounds. The vehicle capacity weight includes
the weight of all occupants, cargo, and all
nonfactory-installed options.
The Tire and Loading Information label also lists the
tire size of the original equipment tires (C) and the
recommended cold tire inflation pressures (D). For
more information on tires and inflation, seeTires on
page 6-51andInflation - Tire Pressure on
page 6-59.
There is also important loading information on the
Certification label. It tells you the Gross Vehicle
Weight Rating (GVWR) and the Gross Axle Weight
Rating (GAWR) for the front and rear axle, see
“Certification Label” later in this section.

Steps for Determining Correct Load Limit1.
Locate the statement “The combined weight of
occupants and cargo should never exceed
XXX kg or XXX lbs” on your vehicle’s placard.
2.
Determine the combined weight of the driver
and passengers that will be riding in your
vehicle.
3.
Subtract the combined weight of the driver
and passengers from XXX kg or XXX lbs.
4.
The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the “XXX” amount equals
1400 lbs and there will be five 150 lb
passengers in your vehicle, the amount of
available cargo and luggage load capacity is
650 lbs (1400−750 (5 x 150) = 650 lbs).
5.
Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated in
Step 4.
6.
If your vehicle will be towing a trailer, the load
from your trailer will be transferred to your
vehicle. Consult this manual to determine how
this reduces the available cargo and luggage
load capacity for your vehicle.
If your vehicle can tow a trailer, seeTowing a
Trailer on page 5-28for important information
on towing a trailer, towing safety rules, and
trailering tips.
