Towing Requirements — Tires
Do not attempt to tow a trailer while using a
compact spare tire.
Do not drive more than 50 mph (80 km/h)
when towing while using a full size spare tire.
Proper tire inflation pressures are essential to
the safe and satisfactory operation of your
vehicle.
Check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire
damage before towing a trailer.
Replacing tires with a higher load carrying
capacity will not increase the vehicle's GVWR
and GAWR limits.
For proper tire inflation procedures
Ú
page 224.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake
system or vacuum system of your vehicle with
that of the trailer. This could cause inadequate
braking and possible personal injury.
An electronically actuated trailer brake
controller is required when towing a trailer with
electronically actuated brakes. When towing a
trailer equipped with a hydraulic surge
actuated brake system, an electronic brake
controller is not required.
Trailer brakes are recommended for trailers
over 1,000 lb (453 kg) and required for trailers
in excess of 2,000 lb (907 kg).
Towing Requirements — Trailer Lights
And Wiring
Whenever you pull a trailer, regardless of the
trailer size, stoplights and turn signals on the
trailer are required for motoring safety.
The Trailer Tow Package may include a four- and
seven-pin wiring harness. Use a factory approved
trailer harness and connector.

NOTE:
Do not cut or splice wiring into the vehicle’s wiring
harness.
The electrical connections are all complete to the
vehicle but you must mate the harness to a trailer
connector. Refer to the following illustrations.

NOTE:

Disconnect trailer wiring connector from the
vehicle before launching a boat (or any other
device plugged into vehicle’s electrical
connect) into water.
Be sure to reconnect once clear from
water area.
Then, during the first 500 miles (805 km)
that a trailer is towed, do not drive over
50 mph (80 km/h) and do not make starts
at full throttle. This helps the engine and
other parts of the vehicle wear in at the
heavier loads.
CAUTION!
WARNING!
Do not connect trailer brakes to your
vehicle's hydraulic brake lines. It can
overload your brake system and cause it to
fail. You might not have brakes when you
need them and could have an accident.
Towing any trailer will increase your stopping
distance. When towing, you should allow for
additional space between your vehicle and
the vehicle in front of you. Failure to do so
could result in an accident.
CAUTION!
If the trailer weighs more than 1,000 lb
(453 kg) loaded, it should have its own brakes
and they should be of adequate capacity.
Failure to do this could lead to accelerated
brake lining wear, higher brake pedal effort,
and longer stopping distances.

In Automatic Locking Mode, the shoulder belt is
automatically pre-locked. The seat belt will still
retract to remove any slack in the shoulder belt.
Use the Automatic Locking Mode anytime a child
restraint is installed in a seating position that has
a seat belt with this feature. Children 12 years old
and under should always be properly restrained
in the rear seat of a vehicle with a rear seat.
How To Engage The Automatic Locking Mode
1. Buckle the combination lap and shoulder belt.
2. Grab the shoulder portion and pull downward until the entire seat belt is extracted.
3. Allow the seat belt to retract. As the seat belt retracts, you will hear a clicking sound. This
indicates the seat belt is now in the Auto -
matic Locking Mode. How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt and
allow it to retract completely to disengage the
Automatic Locking Mode and activate the vehicle
sensitive (emergency) locking mode.
SUPPLEMENTAL RESTRAINT SYSTEMS
(SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on others.
If you are not sure, ask an authorized dealer.
The air bag system must be ready to protect you
in a collision. The Occupant Restraint Controller
(ORC) monitors the internal circuits and intercon -
necting wiring associated with the electrical Air Bag System Components. Your vehicle may be
equipped with the following Air Bag System
Components:
Air Bag System Components
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Supplemental Knee Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
Air Bag Warning Light
The Occupant Restraint Controller
(ORC) monitors the readiness of the
electronic parts of the air bag system
whenever the ignition switch is in the
START or ON/RUN position. If the ignition switch
is in the OFF position or in the ACC position, the
air bag system is not on and the air bags will not
inflate.
The ORC contains a backup power supply system
that may deploy the air bag system even if the
battery loses power or it becomes disconnected
prior to deployment.
WARNING!
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
front air bag can cause death or serious
injury to a child 12 years or younger,
including a child in a rear-facing child
restraint.
Never install a rear-facing child restraint in
the front seat of a vehicle. Only use a
rear-facing child restraint in the rear seat. If
the vehicle does not have a rear seat, do not
transport a rear-facing child restraint in that
vehicle.
WARNING!
The seat belt assembly must be replaced if
the switchable Automatic Locking Retractor
(ALR) feature or any other seat belt function
is not working properly when checked
according to the procedures in the Service
Manual.
Failure to replace the seat belt assembly
could increase the risk of injury in collisions.
Do not use the Automatic Locking Mode to
restrain occupants who are wearing the seat
belt or children who are using booster seats.
The locked mode is only used to install
rear-facing or forward-facing child restraints
that have a harness for restraining the child.

NOTE:
Air bag covers may not be obvious in the interior
trim, but they will open during air bag deployment.
Rollover Events
Side Air Bags and seat belt pretensioners are
designed to activate in certain rollover events.
The Occupant Restraint Controller (ORC)
determines whether deployment in a particular
rollover event is appropriate, based on the
severity and type of collision. Vehicle damage by
itself is not a good indicator of whether or not
Side Air Bags and seat belt pretensioners should
have deployed.
The Side Air Bags and seat belt pretensioners will
not deploy in all rollover events. The rollover
sensing system determines if a rollover event
may be in progress and whether deployment is
appropriate. In the event the vehicle experiences a rollover or near rollover event, and deployment
is appropriate, the rollover sensing system will
deploy the side air bags and seat belt preten
-
sioners on both sides of the vehicle.
The SABICs may help reduce the risk of partial or
complete ejection of vehicle occupants through
side windows in certain rollover or side impact
events.
Air Bag System Components

NOTE:
The Occupant Restraint Controller (ORC) monitors
the internal circuits and interconnecting wiring
associated with electrical Air Bag System
Components listed below:
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Supplemental Knee Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.

NOTE:
Front and/or side air bags will not deploy in all
collisions. This does not mean something is
wrong with the air bag system.
If you do have a collision which deploys the air
bags, any or all of the following may occur:
The air bag material may sometimes cause
abrasions and/or skin reddening to the
occupants as the air bags deploy and unfold.
The abrasions are similar to friction rope burns
or those you might get sliding along a carpet or
gymnasium floor. They are not caused by
contact with chemicals. They are not
permanent and normally heal quickly.
However, if you haven’t healed significantly
within a few days, or if you have any blistering,
see your doctor immediately.
As the air bags deflate, you may see some
smoke-like particles. The particles are a
normal by-product of the process that
generates the non-toxic gas used for air bag
inflation. These airborne particles may irritate
the skin, eyes, nose, or throat. If you have skin
or eye irritation, rinse the area with cool water.
For nose or throat irritation, move to fresh air.
If the irritation continues, see your doctor. If
these particles settle on your clothing, follow
the garment manufacturer’s instructions for
cleaning.
WARNING!
Side Air Bags need room to inflate. Do not
lean against the door or window. Sit upright
in the center of the seat.
Being too close to the Side Air Bags during
deployment could cause you to be severely
injured or killed.
Relying on the Side Air Bags alone could lead
to more severe injuries in a collision. The
Side Air Bags work with your seat belt to
restrain you properly. In some collisions, Side
Air Bags won’t deploy at all. Always wear your
seat belt even though you have Side Air Bags.

Maintaining Your Air Bag System Event Data Recorder (EDR)
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like
situations, such as an air bag deployment or
hitting a road obstacle, data that will assist in
understanding how a vehicle’s systems
performed. The EDR is designed to record data
related to vehicle dynamics and safety systems
for a short period of time, typically 30 seconds or
less. The EDR in this vehicle is designed to record
such data as:
How various systems in your vehicle were
operating;
Whether or not the driver and passenger
safety belts were buckled/fastened;
How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
How fast the vehicle was traveling.
These data can help provide a better
understanding of the circumstances in which
crashes and injuries occur.

NOTE:
EDR data are recorded by your vehicle only if a
non-trivial crash situation occurs; no data are
recorded by the EDR under normal driving condi -
tions and no personal data (e.g., name, gender,
age, and crash location) are recorded. However,
other parties, such as law enforcement, could
combine the EDR data with the type of personally
identifying data routinely acquired during a crash
investigation. To read data recorded by an EDR, special
equipment is required, and access to the vehicle
or the EDR is needed. In addition to the vehicle
manufacturer, other parties, such as law
enforcement, that have the special equipment,
can read the information if they have access to
the vehicle or the EDR.
CHILD RESTRAINTS
Everyone in your vehicle needs to be buckled up
at all times, including babies and children. Every
state in the United States, and every Canadian
province, requires that small children ride in
proper restraint systems. This is the law, and you
can be prosecuted for ignoring it.
Children 12 years or younger should ride properly
buckled up in a rear seat, if available. According
to crash statistics, children are safer when
properly restrained in the rear seats rather than
in the front.
WARNING!
Modifications to any part of the air bag
system could cause it to fail when you need
it. You could be injured if the air bag system
is not there to protect you. Do not modify the
components or wiring, including adding any
kind of badges or stickers to the steering
wheel hub trim cover or the upper passenger
side of the instrument panel. Do not modify
the front fascia/bumper, vehicle body
structure, or add aftermarket side steps or
running boards.
It is dangerous to try to repair any part of the
air bag system yourself. Be sure to tell
anyone who works on your vehicle that it has
an air bag system.
Do not attempt to modify any part of your
air bag system. The air bag may inflate
accidentally or may not function properly if
modifications are made. Take your vehicle to
an authorized dealer for any air bag system
service. If your seat, including your trim cover
and cushion, needs to be serviced in any way
(including removal or loosening/tightening of
seat attachment bolts), take the vehicle to an
authorized dealer. Only manufacturer
approved seat accessories may be used. If it
is necessary to modify the air bag system for
persons with disabilities, contact an
authorized dealer.
WARNING!
In a collision, an unrestrained child can
become a projectile inside the vehicle. The
force required to hold even an infant on your
lap could become so great that you could not
hold the child, no matter how strong you are.
The child and others could be badly injured or
killed. Any child riding in your vehicle should be
in a proper restraint for the child’s size.
