Vehicle Information Menu Items
T
(Vehicle Information):Press this button
to scroll through the following menu items:
Oil Life
Press the vehicle information button until OIL LIFE
REMAINING displays. This display shows an
estimate of the oil’s remaining useful life. If you
see 99% OIL LIFE REMAINING on the display,
that means 99% of the current oil life remains.
The engine oil life system will alert you to change
your oil on a schedule consistent with your
driving conditions.
When the remaining oil life is low, the CHANGE
ENGINE OIL SOON message will appear on
the display. See “CHANGE ENGINE OIL SOON”
underDIC Warnings and Messages on page 267.
You should change your oil as soon as you can.
SeeEngine Oil on page 446. In addition to
the engine oil life system monitoring the oil life,
additional maintenance is recommended in
the Maintenance Schedule in this manual.
SeeScheduled Maintenance on page 563
for more information.Remember, you must reset the OIL LIFE display
yourself after each oil change. It will not reset itself.
Also, be careful not to reset the OIL LIFE display
accidentally at any time other than when the oil has
just been changed. It cannot be reset accurately
until the next oil change. To reset the engine oil life
system, seeEngine Oil Life System on page 449.

Press the vehicle information button until UNITS
displays. This display allows you to select between
English or Metric units of measurement. Once in
this display, press the set/reset button to select
between ENGLISH or METRIC units. All of
the vehicle information will then be displayed in
the unit of measurement selected.
Tire Pressure
If your vehicle has a Tire Pressure Monitor (TPM)
system, the pressure for each tire can be viewed in
the DIC. The tire pressure will be shown in either
pounds per square inch (psi) or kilopascals (kPa).
Press the vehicle information button until the
DIC displays FRONT TIRES PSI (kPa) LEFT ##
RIGHT ##. Press the vehicle information button
again until the DIC displays REAR TIRES PSI (kPa)

The trip odometer has a feature called the
retro-active reset. This can be used to set the
trip odometer to the number of miles (kilometers)
driven since the ignition was last turned on.
This can be used if the trip odometer is not reset
at the beginning of the trip.
To use the retro-active reset feature, press and
hold the trip odometer reset stem for at least
four seconds. The trip odometer will display the
number of miles (mi) or kilometers (km) driven
since the ignition was last turned on and the
vehicle was moving. Once the vehicle begins
moving, the trip odometer will accumulate mileage.
For example, if the vehicle was driven 5 miles
(8 km) before it is started again, and then
the retro-active reset feature is activated, the
display will show 5 miles (8 km). As the vehicle
begins moving, the display will then increase
to 5.1 miles (8.2 km), 5.2 miles (8.4 km), etc.
If the retro-active reset feature is activated after
the vehicle is started, but before it begins moving,
the display will show the number of miles (mi)
or kilometers (km) that were driven during the
last ignition cycle.Oil Life
To access this display, the vehicle must be in
PARK (P). Press the trip odometer reset stem until
OIL LIFE REMAINING displays. This display
shows an estimate of the oil’s remaining useful
life. If you see 99% OIL LIFE REMAINING on
the display, that means 99% of the current oil
life remains. The engine oil life system will alert
you to change your oil on a schedule consistent
with your driving conditions.
When the remaining oil life is low, the CHANGE
ENGINE OIL SOON message will appear on
the display. See “CHANGE ENGINE OIL
SOON” underDIC Warnings and Messages
on page 267. You should change your oil as
soon as you can. SeeEngine Oil on page 446.
In addition to the engine oil life system
monitoring the oil life, additional maintenance
is recommended in the Maintenance Schedule
in this manual. SeeScheduled Maintenance
on page 563for more information.
265

CHANGE ENGINE OIL SOON
This message displays when the engine oil needs
to be changed. When you change the engine
oil, be sure to reset the CHANGE ENGINE OIL
SOON message. SeeEngine Oil Life System
on page 449for information on how to reset the
message. This message clears itself after
10 seconds until the next ignition cycle or until the
message is reset. SeeEngine Oil on page 446
andScheduled Maintenance on page 563for
more information.
CHECK TIRE PRESSURE
If your vehicle has a Tire Pressure Monitor (TPM)
system, this message displays when the
pressure in one or more of the vehicle’s tires
need to be checked. This message also displays
LEFT FRONT, RIGHT FRONT, LEFT REAR,
or RIGHT REAR to indicate which tire needs
to be checked. You can receive more than one
tire pressure message at a time. To read the
other messages that may have been sent at thesame time, press the set/reset button or the trip
odometer reset stem. If a tire pressure message
appears on the DIC, stop as soon as you can.
Have the tire pressures checked and set to those
shown on the Tire Loading Information label.
SeeTires on page 492,Loading Your Vehicle
on page 402, andInation - Tire Pressure
on page 500. The DIC display also shows the
tire pressure values for the front and rear tires
by pressing the vehicle information button.
See “DIC Operation and Displays (With DIC
Buttons)” earlier in this section. If the tire pressure
is low, the low tire pressure warning light comes
on. SeeTire Pressure Light on page 250.DRIVER DOOR OPEN
This message displays and a chime sounds if the
driver’s door is not fully closed and the vehicle
is in a drive gear. Stop and turn off the vehicle,
check the door for obstructions, and close the door
again. Check to see if the message still appears
on the DIC.

After Off-Road Driving
Remove any brush or debris that has collected
on the underbody, chassis, or under the hood.
These accumulations can be a re hazard.
After operation in mud or sand, have the brake
linings cleaned and checked. These substances
can cause glazing and uneven braking. Check the
body structure, steering, suspension, wheels,
tires, and exhaust system for damage. Also, check
the fuel lines and cooling system for any leakage.
Your vehicle will require more frequent service
due to off-road use. Refer to the Maintenance
Schedule for additional information.
Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to
be impaired — by alcohol or drugs, with night
vision problems, or by fatigue.
Here are some tips on night driving.
Drive defensively.
Do not drink and drive.
Adjust the inside rearview mirror to reduce the
glare from headlamps behind you.
Since you cannot see as well, you may need
to slow down and keep more space between
you and other vehicles.
Slow down, especially on higher speed roads.
Your vehicle’s headlamps can light up only so
much road ahead.
In remote areas, watch for animals.
If you are tired, pull off the road in a safe
place and rest.

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal
down while you:
start your engine,
shift into a gear, and
release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the
chocks.
4. Stop and have someone pick up and store
the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when
you’re pulling a trailer. See the Maintenance
Schedule for more on this. Things that are
especially important in trailer operation are
automatic transmission uid (don’t overll), engine
oil, axle lubricant, belts, cooling system and
brake system. Each of these is covered in this
manual, and the Index will help you nd them
quickly. If you’re trailering, it’s a good idea
to review these sections before you start your trip.
Check periodically to see that all hitch nuts and
bolts are tight.

Engine Air Cleaner/Filter
SeeEngine
Compartment Overview
on page 444for the
location of the engine
air cleaner/lter and
the air lter restriction
indicator, if the
vehicle has one.
When to Inspect the Engine
Air Cleaner/Filter
If your vehicle has an air lter restriction indicator,
it lets you know when the engine air cleaner/lter
needs to be replaced. On vehicles with a restriction
indicator, you should inspect the air lter restriction
indicator at every oil change and replace the engine
air cleaner/lter when the indicator tells you to.On vehicles without an air lter restriction indicator,
inspect the air cleaner/lter at the MaintenanceII
intervals and replace it at the rst oil change
after each 50,000 mile (83 000 km) interval.
SeeScheduled Maintenance on page 563for
more information. If you are driving in dusty/dirty
conditions, inspect the lter at each engine oil
change.
How to Inspect the Engine
Air Cleaner/Filter
Vehicles With an Air Filter Restriction
Indicator
Locate the air lter restriction indicator on the
engine air cleaner/lter cover. When the indicator
turns black or is in the red/orange “change”
zone, replace the lter and reset the indicator.
See the steps following to replace the engine
air cleaner/lter and to reset the air lter
restriction indicator.

Consistency of Readings
Always check the uid level at least twice using
the procedure described previously. Consistency
(repeatable readings) is important to maintaining
proper uid level. If readings are still inconsistent,
contact your dealer.
How to Add Automatic
Transmission Fluid
Refer to the Maintenance Schedule to determine
what kind of transmission uid to use. See
Recommended Fluids and Lubricants on page 574.
Using a funnel, add uid down the transmission
dipstick tube only after checking the transmission
uid while it is hot. A cold check is used only
as a reference. If the uid level is low, add only
enough of the proper uid to bring the level up to
the HOT area for a hot check. It does not take
much uid, generally less than one pint (0.5 L).
Do not overll.Notice:Use of the incorrect automatic
transmission uid may damage your vehicle,
and the damages may not be covered by
your warranty. Always use the automatic
transmission uid listed inRecommended
Fluids and Lubricants on page 574.
After adding uid, recheck the uid level as
described under “How to Check Automatic
Transmission Fluid,” earlier in this section.
When the correct uid level is obtained, push
the dipstick back in all the way; then ip the
handle down to lock the dipstick in place.
Engine Coolant
If your vehicle has the DURAMAX®Diesel engine,
see the DURAMAX®Diesel manual for more
information.
The cooling system in your vehicle is lled with
DEX-COOL
®engine coolant. This coolant is
designed to remain in your vehicle for ve years or
150,000 miles (240 000 km), whichever occurs rst,
if you add only DEX-COOL
®extended life coolant.
