WARNING!
Adjusting a seat while driving may be
dangerous. Moving a seat while driving
could result in loss of control which could
cause a collision and serious injury or
death.
Seats should be adjusted before fastening
the seat belts and while the vehicle is
parked. Serious injury or death could result
from a poorly adjusted seat belt.
Do not ride with the seatback reclined so
that the shoulder belt is no longer resting
against your chest. In a collision you could
slide under the seat belt, which could result
in serious injury or death.
Do not place the seat belt webbing behind
the third row stow clip when using the seat
belt to restrain an occupant. The seat belt
will not be positioned properly on the occu-
pant and they could be more seriously
injured in an accident as a result.

Drivers must be careful when backing up
even when using ParkSense. Always check
carefully behind your vehicle, look behind
you, and be sure to check for pedestrians,
animals, other vehicles, obstructions, and
blind spots before backing up. You are
responsible for safety and must continue to
pay attention to your surroundings. Failure
to do so can result in serious injury or
death.
Before using ParkSense, it is strongly
recommended that the ball mount and
hitch ball assembly be disconnected from
the vehicle when the vehicle is not used for
towing. Failure to do so can result in injury
or damage to vehicles or obstacles
because the hitch ball will be much closer
to the obstacle than the rear fascia when
the vehicle sounds the continuous tone.
Also, the sensors could detect the ball
mount and hitch ball assembly, depending
on its size and shape, giving a false indica-
tion that an obstacle is behind the vehicle.
CAUTION!
ParkSense is only a parking aid and it is
unable to recognize every obstacle,
including small obstacles. Parking curbs
might be temporarily detected or not
detected at all. Obstacles located above or
below the sensors will not be detected
when they are in close proximity.
The vehicle must be driven slowly when
using ParkSense in order to be able to stop
in time when an obstacle is detected. It is
recommended that the driver looks over
his/her shoulder when using ParkSense.

Do not tow a trailer at all during the first
500 miles (805 kmyfWKHQHZYHKLFOHLV driven. The engine, axle or other parts could
be damaged.
Then, during the first 500 miles (805 kmyf that a trailer is towed, do not drive over
50 mph (80 km/hyfDQGGRQRWPDNHVWDUWV
at full throttle. This helps the engine and
other parts of the vehicle wear in at the
heavier loads.
WARNING!
Make certain that the load is secured in the
trailer and will not shift during travel. When
trailering cargo that is not fully secured,
dynamic load shifts can occur that may be
difficult for the driver to control. You could
lose control of your vehicle and have a colli -
sion.
When hauling cargo or towing a trailer, do
not overload your vehicle or trailer. Over -
loading can cause a loss of control, poor
performance or damage to brakes, axle,
engine, transmission, steering, suspension,
chassis structure or tires.
Safety chains must always be used
between your vehicle and trailer. Always
connect the chains to the hook retainers of
the vehicle hitch. Cross the chains under
the trailer tongue and allow enough slack
for turning corners.

Do not connect trailer brakes to your
vehicle's hydraulic brake lines. It can over-
load 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 stop -
ping 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.

damage to the transfer case.
The transmission must be in PARK for
recreational towing.

WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open
or the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the
Malfunction Indicator Light to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a
vehicle. You could be burned. Always place
fuel containers on the ground while filling.

SERVICING AND MAINTENANCE
SC\b\fED SERVICING
Your vehicle is equipped with an automatic oil
change indicator system. The oil change
indicator system will remind you that it is time to
take your vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate. This
means that service is required for your vehicle.
Operating conditions such as frequent
short-trips, trailer tow, extremely hot or cold
ambient temperatures, and E85 fuel usage will
influence when the “Oil Change Required”
message is displayed. Have your vehicle
serviced as soon as possible, within the next
500 miles (805 kmyf.An authorized dealer will reset the oil change
indicator message after completing the
scheduled oil change. NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 kmyf
12 months or 350 hours of engine run time,
whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for
fleet customers.
Once A Month Or Before A Long Trip:
Check engine oil level
Check windshield washer fluid level
Check the tire inflation pressures and look
for unusual wear or damage
Check the fluid levels of the coolant reservoir,
brake master cylinder and fill as needed.
Check function of all interior and exterior
lights
MAINTENANCE PLAN
Refer to the Maintenance Plan for the required
maintenance intervals.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
Change oil and filter.
Rotate the tires. Rotate at the first sign of
irregular wear, even if it occurs before the
oil indicator system turns on.
Inspect battery and clean and tighten termi -
nals as required.
Inspect the CV/Universal joints.
Inspect brake pads, shoes, rotors, drums,
hoses and parking brake.
Inspect engine cooling system protection
and hoses.
Inspect exhaust system.
Inspect engine air cleaner filter if using in
dusty or off-road conditions. Replace
engine air cleaner filter, as necessary.
