Do not attempt sharp turns, abrupt maneuvers,
or other unsafe driving actions that can cause
loss of vehicle control. Failure to operate this
vehicle safely may result in a collision, rollover
of the vehicle, and severe or fatal injury. Drive
carefully.
Failure to use the driver and passenger seat
belts provided is a major cause of severe or
fatal injury. In a rollover crash, an unbelted
person is significantly more likely to die than a
person wearing a seat belt. Always buckle up.IMPORTANT NOTICEALL MATERIAL CONTAINED IN THIS PUBLI-

WARNING!
Deployed air bags and seat belt pretensioners
cannot protect you in another collision. Have
the air bags, seat belt pretensioners, and the
front seat belt retractor assemblies replaced
by an authorized dealer immediately. Also,
have the Occupant Restraint Controller
(ORC) system serviced as well.
Maintaining Your Air Bag System
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 right side
of the instrument panel. Do not modify the
front bumper, vehicle body structure, or add
aftermarket side steps or running boards.
(Continued)
WARNING! (Continued)
• 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 ser-
viced in any way (including removal or
loosening/tightening of seat attachment
bolts), take the vehicle to your 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 your authorized
dealer. Air Bag Warning Light
You will want to have the air bags
ready to inflate for your protection
in a collision. The Air Bag Warning
Light monitors the internal circuits
and interconnecting wiring associ-
ated with air bag system electrical
components. While the air bag system is de-
signed 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 turned to 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 inter-
mittently or remains on while driving.

WARNING!
•An incorrectly anchored tether strap could
lead to increased head motion and possible
injury to the child. Use only the anchor
positions directly behind the child seat to
secure a child restraint top tether strap.
• Do not use the cargo tie downs located on
the load floor. Improper usage of the tether
can lead to a failure of an infant or child
restraint. The child could be badly injured
or killed. Transporting Pets
Air Bags deploying in the front seat could harm
your pet. An unrestrained pet will be thrown
about and possibly injured, or injure a passen-
ger during panic braking or in an accident. Pets
should be restrained in the rear seat in pet
harnesses or pet carriers that are secured by
seat belts.
ENGINE BREAK-IN
RECOMMENDATIONS
A long break-in period is not required for the
engine and drivetrain (transmission and axle) in
your vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles (100 km),
speeds up to 50 or 55 mph (80 or 90 km/h) are
desirable.
While cruising, brief full-throttle acceleration
within the limits of local traffic laws contributes
to a good break-in. Wide-open throttle accel-
eration in low gear can be detrimental and
should be avoided.
The engine oil installed in the engine at the
factory is a high-quality energy conserving type lubricant. Oil changes should be consistent
with anticipated climate conditions under
which vehicle operations will occur. For the
recommended viscosity and quality grades,
refer to “Maintenance Procedures” in “Main-
taining Your Vehicle”. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER BE
USED.
A new engine may consume some oil during its
first few thousand miles (kilometers) of opera-
tion. This should be considered a normal part
of the break-in and not interpreted as an indi-
cation of difficulty.
Additional Requirements For Diesel
Engine — If Equipped
During the first 1500 km avoid heavy loads, e.g.
driving at full throttle. Do not exceed 2/3 of the
maximum permissible engine speed for each
gear. Change gear in good time. Do not shift
down a gear manually in order to brake.
SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE
CARGO AREA.

Display Warnings And Maintenance
“Clean Radar Sensor In Front Of Vehicle”
Warning
The ACC “Clean Radar Sensor In Front Of
Vehicle” warning will display when conditions
temporarily limit system performance. This
most often occurs at times of poor visibility,
such as in snow or heavy rain. The ACC system
may also become temporarily blinded due to
obstructions, such as mud, dirt or ice. In these
cases, the EVIC will display “Clean Radar Sen-
sor In Front Of Vehicle” and the system will
deactivate.
The “Clean Radar Sensor In Front Of Vehicle”
message can sometimes be displayed while
driving in highly reflective areas (i.e. tunnels
with reflective tiles, or ice and snow). The ACC
system will recover after the vehicle has left
these areas. Under rare conditions, when the radar is not tracking any vehicles or objects in
its path this warning may temporarily occur.
NOTE:
If the ACC “Clean Radar Sensor In Front Of
Vehicle” warning is active Normal (Fixed
Speed) Cruise Control is still available. For
additional information refer to “Normal (Fixed
Speed) Cruise Control Mode” in this section.
If weather conditions are not a factor, the driver
should examine the sensor. It may require
cleaning or removal of an obstruction. The
sensor is located in the center of the vehicle
behind the lower grille.
