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.

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.

Rear Lifting Point
Rear Jacking Location

5. Raise the vehicle by turning the jack screw clockwise. Raise the vehicle only until the tire just clears the
surface and enough clearance is obtained to install
the spare tire. Minimum tire lift provides maximum
stability. 6. Remove the lug nuts and wheel.
7. Mount the spare tire on the axle.
8. Install the lug nuts with the cone-shaped end toward
the wheel. Lightly tighten the lug nuts clockwise.
9. Lower the vehicle by turning the jack screw to the counterclockwise, and remove the jack.
10. Finish tightening the wheel bolts. Push down on the wrench while at the end of the handle for increased
leverage. Tighten the wheel bolts in a star pattern
until each wheel bolt has been tightened twice Úpage 368. If in doubt about the correct tightness,
have them checked with a torque wrench by an
authorized dealer or at a service station.
11. After 25 miles (40 km), check the lug nut torque with a torque wrench to ensure that all lug nuts are
properly seated against the wheel. 12. Remove the jack assembly and wheel blocks.
13. Secure the jack and tools in their proper locations.
14. Secure the damaged wheel/tire on the spare tire
carrier. Torque down lug nuts and locking lug nut.
15. Return the lock bolt to the lock position on the camera cover by turning the lock clockwise using the
provided #40 torx head driver and ratchet. Then,
reinstall the camera cover by slipping it over the
camera/tire carrier until it snaps into place.

Lock Bolt Location

WARNING!
Raising the vehicle higher than necessary can make the
vehicle less stable. It could slip off the jack and hurt
someone near it. Raise the vehicle only enough to
change the tire.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the wheel nuts fully until the vehicle has
been lowered. Failure to follow this warning may result
in serious injury.
WARNING!
A loose tire or jack thrown forward in a collision or hard
stop, could endanger the occupants of the vehicle.
Always stow the jack parts and the spare tire in the
places provided.

TECHNICAL SPECIFICATIONS
VEHICLE IDENTIFICATION NUMBER (VIN)
The VIN is found on the left front corner of the A-pillar,
visible from outside of the vehicle through the windshield.

Vehicle Identification Number

NOTE:It is illegal to remove or alter the VIN plate.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake
systems. If either of the two hydraulic systems lose normal
capability, the remaining system will still function.
However, there will be some loss of overall braking
effectiveness. You may notice increased pedal travel during application, greater pedal force required to slow or
stop, and potential activation of the Brake Warning Light.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off) the
brakes will still function. However, the effort required to
brake the vehicle will be much greater than that required
with the power system operating.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle,
the lug nuts/bolts should be torqued using a properly
calibrated torque wrench using a six-sided (hex) deep wall
socket.
TORQUE SPECIFICATIONS
**Use only authorized dealer recommended lug nuts/bolts
and clean or remove any dirt or oil before tightening.
Inspect the wheel mounting surface prior to mounting the
tire and remove any corrosion or loose particles.Spare Tire Torque Specifications
**Use only authorized dealer recommended lug nuts/bolts
and clean or remove any dirt or oil before tightening.
Spare tire torque is for the spare tire carrier located on the
swing gate.

sure that all the lug nuts/bolts are properly seated against
the wheel.
FUEL REQUIREMENTS — GASOLINE ENGINE
While operating on gasoline with the required octane
number, hearing a light knocking sound from the engine is
not a cause for concern. However, if the engine is heard
making a heavy knocking sound, see a dealer
immediately. Use of gasoline with an octane number lower
than recommended can cause engine failure and may
void the New Vehicle Limited Warranty. Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of gasoline before
considering service for the vehicle.
2.0L ENGINE
This engine is designed to meet all emissions
requirements, and provide satisfactory fuel
economy and performance, when using
high-quality unleaded regular gasoline having
an octane rating of 87, as specified by the (R+M)/
2 method. The use of 91 or higher octane premium
gasoline will allow these engines to operate to optimal
performance. This increase in performance is most
noticeable in hot weather or under heavy load conditions
such as while towing.
3.6L ENGINE
This engine is designed to meet all emissions
regulations and provide satisfactory fuel
economy and performance when using
high-quality unleaded regular gasoline having
an octane rating of 87 as specified by the (R+M)/
2 method. The use of higher octane premium gasoline will
not provide any benefit over regular gasoline in these
engines.
REFORMULATED GASOLINE
Many areas of the country require the use of cleaner
burning gasoline referred to as “reformulated gasoline”.
Reformulated gasoline contains oxygenates and are
specifically blended to reduce vehicle emissions and
improve air quality. The use of reformulated gasoline is recommended.
Properly blended reformulated gasoline will provide
improved performance and durability of engine and fuel
system components.
MATERIALS ADDED TO FUEL
Besides using unleaded gasoline with the proper octane
rating, gasolines that contain detergents, corrosion and
stability additives are recommended. Using gasolines that
have these additives will help improve fuel economy,
reduce emissions, and maintain vehicle performance.
Designated TOP TIER Detergent Gasoline
contains a higher level of detergents to further
aide in minimizing engine and fuel system
deposits. When available, the usage of TOP
TIER Detergent gasoline is recommended. Visit
www.toptiergas.com for a list of TOP TIER Detergent
Gasoline retailers.
Indiscriminate use of fuel system cleaning agents should
be avoided. Many of these materials intended for gum and
varnish removal may contain active solvents or similar
ingredients. These can harm fuel system gasket and
diaphragm materials.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts/bolts fully until the vehicle has
been lowered. Failure to follow this warning may result
in personal injury.
