174STARTING AND OPERATING
(Continued)
Towing Requirements — Tires
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 further information
Úpage 345.
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 actu -
ated 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,
stop lights 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 the trailer wiring connector from the vehicle
(or any other device plugged into the vehicle's electrical
connectors) before launching a boat into water.
 Be sure to reconnect once clear from water area.

Four-Pin Connector

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 acci -
dent.
 Towing any trailer will increase your stopping
distance. When towing, you should allow for addi -
tional space between your vehicle and the vehicle in
front of you. Failure to do so could result in an acci -
dent.
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.
WARNING!

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 interconnecting 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
 Front and Side Impact Sensors
 Seat Belt Pretensioners
 Seat Track Position Sensors
 Occupant Classification System
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.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition switch is first in the ON/
RUN position. After the self-check, the Air Bag Warning
Light will turn off. If the ORC detects a malfunction in any
part of the system, it turns on the Air Bag Warning Light,
either momentarily or continuously. A single chime will
sound to alert you if the light comes on again after initial
startup.
The ORC also includes diagnostics that will illuminate the
instrument panel Air Bag Warning Light if a malfunction is
detected that could affect the air bag system. The
diagnostics also record the nature of the malfunction. While the air bag system is designed to be maintenance
free, if any of the following occurs, have an authorized
dealer service the air bag system immediately.

The Air Bag Warning Light does not come on during the
four to eight seconds when the ignition switch is first in
the ON/RUN position.
 The Air Bag Warning Light remains on after the four to
eight-second interval.
 The Air Bag Warning Light comes on intermittently or
remains on while driving.
NOTE:If the speedometer, tachometer, or any engine related
gauges are not working, the Occupant Restraint Controller
(ORC) may also be disabled. In this condition the air bags
may not be ready to inflate for your protection. Have an
authorized dealer service the air bag system immediately.
Redundant Air Bag Warning Light
If a fault with the Air Bag Warning Light is
detected, which could affect the Supplemental
Restraint System (SRS), the Redundant Air Bag
Warning Light will illuminate on the instrument
panel. The Redundant Air Bag Warning Light will stay on

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.
WARNING!
WARNING!
Ignoring the Air Bag Warning Light in your instrument
panel could mean you won’t have the air bag system to
protect you in a collision. If the light does not come on
as a bulb check when the ignition is first turned on,
stays on after you start the vehicle, or if it comes on as
you drive, have an authorized dealer service the air bag
system immediately.

SAFETY275
(Continued)
Side Impacts
The Side Air Bags are designed to activate in certain side
impacts. The Occupant Restraint Controller (ORC)
determines whether the deployment of the Side Air Bags
in a particular impact event is appropriate, based on the
severity and type of collision. The side impact sensors aid
the ORC in determining the appropriate response to
impact events. The system is calibrated to deploy the Side
Air Bags on the impact side of the vehicle during impacts
that require Side Air Bag occupant protection. In side
impacts, the Side Air Bags deploy independently; a left
side impact deploys the left Side Air Bags only and a
right-side impact deploys the right Side Air Bags only.
Vehicle damage by itself is not a good indicator of whether
or not Side Air Bags should have deployed.
The Side Air Bags will not deploy in all side collisions,
including some collisions at certain angles, or some side
collisions that do not impact the area of the passenger
compartment. The Side Air Bags may deploy during angled
or offset frontal collisions where the front air bags deploy.
Side Air Bags are a supplement to the seat belt restraint
system. Side Air Bags deploy in less time than it takes to
blink your eyes.
NOTE:Air bag covers may not be obvious in the interior trim, but
they will open during air bag deployment.
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
 Front and Side Impact Sensors
 Seat Belt Pretensioners
 Seat Track Position Sensors
 Occupant Classification System
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.
WARNING!
Occupants, including children, who are up against or
very close to Side Air Bags can be seriously injured or
killed. Occupants, including children, should never
lean on or sleep against the door, side windows, or
area where the side air bags inflate, even if they are
in an infant or child restraint.
Seat belts (and child restraints where appropriate)
are necessary for your protection in all collisions.
They also help keep you in position, away from an
inflating Side Air Bag. To get the best protection from
the Side Air Bags, occupants must wear their seat
belts properly and sit upright with their backs against
the seats. Children must be properly restrained in a
child restraint or booster seat that is appropriate for
the size of the child.
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 deploy -
ment 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.
WARNING!

SAFETY277
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 acceler -
ator 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 conditions 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.

There are different sizes and types of restraints for children
from newborn size to the child almost large enough for an
adult safety belt. Always check the child seat Owner’s
Manual to make sure you have the correct seat for your
child. Carefully read and follow all the instructions and
warnings in the child restraint Owner’s Manual and on all
the labels attached to the child restraint.

Before buying any restraint system, make sure that it has
a label certifying that it meets all applicable Safety
Standards. You should also make sure that you can install
it in the vehicle where you will use it.
NOTE:

For additional information, refer to http://
www.nhtsa.gov/parents-and-caregivers or call:
1–888–327–4236
 Canadian residents should refer to Transport Canada’s
website for additional information: https://
www.tc.gc.ca/en/services/road/
child-car-seat-safety.html
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 instru -
ment 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 pro -
jectile 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.
