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 acceleration in low gear can be detri-
mental 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 recom-
mended viscosity and quality grades, refer to “Mainte-
nance Procedures” in “Maintaining Your Vehicle”.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil
in the engine or damage may result.
NOTE:A new engine may consume some oil during its
first few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in and
not interpreted as a problem.
SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE CARGO
AREA.

WARNING!
•Cargo tie-downs are not safe anchors for a child
seat tether strap. In a sudden stop or accident, a
tie-down could pull loose and allow the child seat
to come loose. A child could be badly injured. Use
only the anchors provided for child seat tethers.
•To help protect against personal injury, passengers
should not be seated in the rear cargo area. The rear
cargo space is intended for load carrying purposes
only, not for passengers, who should sit in seats
and use seat belts.
WARNING!
The weight and position of cargo and passengers can

handling. To avoid loss of control resulting in per-
sonal injury, follow these guidelines for loading your
vehicle:
•Do not carry loads that exceed the load limits
described on the label attached to the left door or
left door center pillar.
•Always place cargo evenly on the cargo floor. Put
heavier objects as low and as far forward as pos-
sible.
•Place as much cargo as possible in front of the rear
axle. Too much weight or improperly placed weight
over or behind the rear axle can cause the vehicle to
sway.
•Do not pile luggage or cargo higher than the top of
the seatback. This could impair visibility or be-
come a dangerous projectile in a sudden stop or
accident.

5. LaneSense — If Equipped
The LaneSense system provides the driver with
visual and steering torque warnings when the
vehicle starts to drift out of its lane uninten-
tionally without the use of a turn signal.
•When the LaneSense system is ON and ready the
lane lines and LaneSense indicator are the color gray.
•When the LaneSense system is armed, the lane lines
change to white and the LaneSense indicator
changes to green.
•When the LaneSense system senses a lane cross
situation, the approaching lane line and the La-
neSense indicator change from white to yellow.
For further information, refer to “Lanesense — If
Equipped” in “Understanding The Features Of Your
Vehicle”.
6. Fuel Gauge
Fuel Gauge displays the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position.

(11.0 L) this light will turn on, and remain on until
fuel is added.
8. Rear Axle Lock Indicator — If Equipped
This light indicates when the rear axle lock has
been activated.
9. Reconfigurable Yellow Telltale Display

•LaneSence Failure Telltale
This telltale will turn on to indicate that the
LaneSense Departure has detected a failure.
•Diesel Low Diesel Exhaust Telltale — If Equipped
This telltale will turn on to indicate the Diesel
Exhaust Fluid (DEF) is low
•rear Axle Locker Telltale
This light indicates when the rear axle lock has
been activated.

This telltale will turn on to indicate the wind-
shield washer fluid is low.
•Diesel water In Fuel Telltale — If Equipped
The “Water In Fuel Indicator Light” will illu-
minate when there is water detected in the fuel
filters. If this light remains on, DO NOT start
the vehicle before you drain the water from the
fuel filters to prevent engine damage. Refer to “Mainte-
nance Procedures/Draining Fuel/Water Separator Fil-
ters” in “Maintaining Your Vehicle” for further
information.

12. Amber Reconfigurable Telltale Display
•Transmission Temperature Warning Light
This light indicates that there is excessive
transmission fluid temperature that might
occur with severe usage such as trailer
towing. It may also occur when operating
the vehicle in a high torque converter slip condition,
such as 4-wheel-drive operation (e.g., snow plowing,
off- road operation). If this light comes on, stop the
vehicle and run the engine at idle or faster, with the
transmission in NEUTRAL until the light goes off.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is illumi-
nated you could cause the fluid to boil over, come in
contact with hot engine or exhaust components and
cause a fire.

•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
•Inspect the radiator for mud and debris and clean as
required.
•Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
•Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
•After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
•If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a
wheel imbalance and freeing the wheels of it will
correct the situation.
POWER STEERING
The electric power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will vary its assist to provide

•Do not “ride” the brakes by resting your foot on the
pedal. This could overheat the brakes and result in
unpredictable braking action, longer stopping dis-
tances, or brake damage.
•When descending mountains or hills, repeated braking
can cause brake fade with loss of braking control.
Avoid repeated heavy braking by downshifting the
transmission or locking out overdrive whenever pos-
sible.
•Engines may idle at higher speeds during warm-up,
which could cause rear wheels to spin and result in
loss of vehicle control. Be especially careful while
driving on slippery roads, in close-quarter maneuver-
ing, parking, or stopping.
•Do not drive too fast for road conditions, especially
when roads are wet or slushy. A wedge of water can
build up between the tire tread and the road. This
hydroplaning action can cause loss of traction, braking
ability, and control.
•After going through deep water or a car wash, brakes
may become wet, resulting in decreased performance
and unpredictable braking action. Dry the brakes by
gentle, intermittent pedal action while driving at very
slow speeds.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system, Brake Limited
Differential (BLD), functions similar to a limited slip
differential and controls the wheel spin across a driven
axle. If one wheel on a driven axle is spinning faster than
the other, the system will apply the brake of the spinning
