sounds for several seconds to remind the front
passenger to buckle their safety belt. This only occurs if
the passenger airbag is enabled. SeePassenger
Sensing System on page 1-64for more information.
The passenger safety belt light, located on the

Low Fuel Warning Light
The light next to the fuel gage will come on briey when
you are starting the engine.
This light comes on when the fuel tank is low on fuel.
To turn it off, add fuel to the fuel tank. SeeFuel on
page 5-5.
Check Gas Cap Light
If your vehicle has this
light, it will come on if your
gas cap is not securely
fastened.
SeeMalfunction Indicator Lamp on page 3-38for more
information.
Driver Information Center (DIC)
Your vehicle may have this feature. The Driver
Information Center (DIC) display is located on the
instrument panel cluster, below the speedometer.
If your vehicle has DIC buttons, they are located on
the steering wheel. The DIC can display information
such as the trip odometer, fuel economy, customization
features, and warning/status messages.
If your vehicle does not have DIC steering wheel
buttons, you will not have all of the features listed.
Scroll through the odometer and trip odometer by
pressing the trip odometer reset stem located on the
instrument panel cluster. Turn off, or acknowledge, DIC
messages by pressing the trip odometer reset stem.
SeeSpeedometer and Odometer on page 3-29for
information on features for vehicles without DIC buttons.

Always reset the engine oil life system after an oil
change. To reset the engine oil life system, seeEngine
Oil Life System on page 5-18.
In addition to the engine oil life system monitoring the
oil life, additional maintenance is recommended in
the Maintenance Schedule in this manual. SeeEngine
Oil on page 5-15andScheduled Maintenance on
page 6-4.

DIC Warnings and Messages
Messages are displayed on the DIC to notify the driver
that the status of the vehicle has changed and that
some action may be needed to correct the condition.
Multiple messages may appear one after another.
Some messages may not require immediate action.
Press any of the DIC buttons on the steering wheel or
the trip odometer reset stem on the instrument panel
cluster to acknowledge that you received the messages
and to clear them from the display.
Some messages cannot be cleared from the display
because they are more urgent. These messages require
action before they can be removed from the DIC
display. Take any messages that appear on the display
seriously and remember that clearing the messages
will only make the messages disappear, not correct the
problem.
The following are the possible messages that can be
displayed and some information about them.
3-51

CHANGE ENGINE OIL
This message displays when the engine oil needs to be
changed and service is required for your vehicle.
SeeScheduled Maintenance on page 6-4andEngine
Oil on page 5-15for more information. Also see
Engine Oil Life System on page 5-18for information
on how to reset the message. This message clears itself
after 10 seconds until the next ignition cycle.
CHECK TIRE PRESSURE
On vehicles with the Tire Pressure Monitor System
(TPMS), this message displays when the pressure in
one or more of the vehicle’s tires needs to be checked.
If a tire pressure message appears on the DIC, stop

and set to those shown on the Tire Loading Information
label. SeeTires on page 5-53,Loading the Vehicle
on page 4-31, andInflation - Tire Pressure on
page 5-60. The DIC also shows the tire pressure

If the tire pressure is low, the low tire pressure
warning light comes on. SeeTire Pressure Light on
page 3-38.
CHECK WASHER FLUID
This message displays if the washer uid level is low.
Adding washer uid to the windshield washer uid
reservoir clears this message. SeeWindshield Washer

optimal rate and the vehicle will lose the ability to enter
the fuel economy mode. The vehicle is safe to drive,
however you should have the electrical system checked
by your dealer/retailer.

you do not have the benet of StabiliTrak, so reduce
your speed and drive accordingly.
3-54

StabiliTrak Off
In this mode, both stability control and part of the traction
control system are disabled. The vehicle will still have
brake-traction control, but will not be able to use the
engine speed management system. System noises may
be heard as a result of the brake-traction control coming
on. If the controller detects excessive wheel spin in this
mode, the StabiliTrak indicator light may blink and the
STABILITRAK ACTIVE message may be displayed
to warn the driver that damage may occur to the
transfer case.
It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn
the system off if the vehicle is stuck in sand, mud, ice orsnow, and you may want to “rock” the vehicle in an
attempt to free it. It may also be necessary to turn off the
system when driving in extreme off-road conditions
where high wheel spin is required. SeeIf Your Vehicle
is Stuck in Sand, Mud, Ice, or Snow on page 4-30
for more information.
When the transfer case is in 4LO, the stability system is
automatically disabled. The StabiliTrak light will come
on and the STABILITRAK OFF message will appear on
the DIC. The StabiliTrak system cannot be turned on
until the vehicle is switched to 2HI, 4HI, or 4AWD.
The following chart describes the StabiliTrak system
events and the corresponding messages and lights that
will be displayed on the instrument panel cluster.

CAUTION: (Continued)

Open a window about two inches (5 cm) on
the side of the vehicle that is away from the
wind to bring in fresh air.
Fully open the air outlets on or under the
instrument panel.
Adjust the Climate Control system to a setting
that circulates the air inside the vehicle and
set the fan speed to the highest setting. See
Climate Control System in the Index.
For more information about carbon monoxide, see
Engine Exhaust on page 2-37.
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill you.
You cannot see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking the exhaust.Run the engine for short periods only as needed to
keep warm, but be careful.
To save fuel, run the engine for only short periods as
needed to warm the vehicle and then shut the engine
off and close the window most of the way to save heat.
Repeat this until help arrives but only when you feel
really uncomfortable from the cold. Moving about
to keep warm also helps.
If it takes some time for help to arrive, now and then when
you run the engine, push the accelerator pedal slightly so
the engine runs faster than the idle speed. This keeps the
battery charged to restart the vehicle and to signal for
help with the headlamps. Do this as little as possible to
save fuel.
4-29

Driving with a Trailer
{CAUTION:
When towing a trailer, exhaust gases may collect
at the rear of the vehicle and enter if the liftgate,
trunk/hatch, or rear-most window is open.
Engine exhaust contains carbon monoxide (CO)
which cannot be seen or smelled. It can cause
unconsciousness and even death.
To maximize safety when towing a trailer:
Have the exhaust system inspected for leaks
and make necessary repairs before starting
a trip.
Never drive with the liftgate, trunk/hatch, or
rear-most window open.
Fully open the air outlets on or under the
instrument panel.
Adjust the Climate Control system to a setting
that brings in only outside air and set the fan
speed to the highest setting. See Climate
Control System in the Index.
For more information about carbon monoxide, see
Engine Exhaust on page 2-37.Towing a trailer requires a certain amount of experience.
Get to know the rig before setting out for the open road.
Get acquainted with the feel of handling and braking with
the added weight of the trailer. And always keep in mind
that the vehicle you are driving is now longer and not as
responsive as the vehicle is by itself.
Before starting, check all trailer hitch parts and
attachments, safety chains, electrical connectors, lamps,
tires and mirror adjustments. If the trailer has electric
brakes, start the vehicle and trailer moving and then
apply the trailer brake controller by hand to be sure the
brakes are working. This checks the electrical connection
at the same time.
During the trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as
you would when driving the vehicle without a trailer.
This can help to avoid situations that require heavy
braking and sudden turns.
Passing
More passing distance is needed when towing a trailer.
Because the rig is longer, it is necessary to go much
farther beyond the passed vehicle before returning to
the lane.
