In Brief 25Loading Information label. See
Vehicle Load Limits 0 200 . The
warning light will remain on until the
tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the
tire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See Tire Pressure Monitor System
0 329 .
Tire Fill Alert (If Equipped)
This feature provides visual and
audible alerts outside the vehicle to
help when inflating an underinflated
tire to the recommended cold tire
pressure. See “ Tire Fill Alert (If
Equipped) ” under Tire Pressure
Monitor Operation 0 330 . Fuel (L83 5.3L V8 Engine) Regular Fuel
Use only unleaded gasoline rated
87 octane or higher in your vehicle.
Do not use gasoline with an octane
rating lower as it may result in
vehicle damage and lower fuel
economy. See Fuel 0 254 .
Fuel (L86 6.2L V8 Engine)
Premium Recommended Fuel
Use premium 93 octane unleaded
gasoline in your vehicle. Unleaded
gasoline with an octane rating as low as 87 may be used, but it will
reduce performance and fuel
economy. See Fuel 0 254 .
E85 or FlexFuel
FlexFuel Possible
Certain models are compatible with
E85 fuel. See E85 or FlexFuel
0 256 .
Engine Oil Life System The engine oil life system calculates
engine oil life based on vehicle use
and displays a DIC message when
it is necessary to change the engine
oil and filter. The oil life system
should be reset to 100% only
following an oil change.

wiper is on, the wiper returns to the
parked position and stops.
Rear Wiper Arm Assembly
Protection
When using an automatic car wash,
move the rear wiper control to OFF
to disable the rear wiper. In some
vehicles, if the transmission is in
N (Neutral) and the vehicle speed is
very slow, the rear wiper will
automatically park under the rear
spoiler.
The wiper operations return to
normal when the transmission is no
longer in N (Neutral) or the vehicle
speed has increased.
Reverse Gear Wipes
If the rear wiper control is off, the
rear wiper will automatically operate
continuously when the shift lever is
in R (Reverse), and the front
windshield wiper is performing low
or high speed wipes. If the rear
wiper control is off, the shift lever is
in R (Reverse), and the front
windshield wiper is performing interval wipes, then the rear wiper
automatically performs interval
wipes.
This feature can be turned on or off.
See Vehicle Personalization 0 158 .
The windshield washer reservoir is
used for the windshield and the rear
window. Check the fluid level in the
reservoir if either washer is not
working. See Washer Fluid 0 296 .
Compass The vehicle may have a compass
display on the Driver Information
Center (DIC). The compass receives
its heading and other information
from the Global Positioning
System (GPS) antenna, StabiliTrak,
and vehicle speed information.
The compass system is designed to
operate for a certain number of
miles or degrees of turn before
needing a signal from the GPS
satellites. When the compass
display shows CAL, drive the
vehicle for a short distance in an
open area where it can receive a
GPS signal. The compass system will automatically determine when a
GPS signal is restored and provide
a heading again.
Clock Setting the Time and Date with
Center Stack Controls To set the time or date:

number is calculated based on the
number of L/100 km (mpg) recorded
since the last time this menu item
was reset. This number reflects only
the approximate average fuel
economy that the vehicle has right
now, and will change as driving
conditions change.
The Average Speed display shows
the average speed of the vehicle in
kilometers per hour (km/h) or miles
per hour (mph). This average is
calculated based on the various
vehicle speeds recorded since the
last reset of this value.
Press and hold

average speed. Or press
p and
select reset in the menu.
Fuel Range and Instantaneous
Fuel Economy : Shows the
approximate distance the vehicle
can be driven without refueling.
LOW will be displayed when the
vehicle is low on fuel. The fuel
range estimate is based on an
average of the vehicle's fuel economy over recent driving history
and the amount of fuel remaining in
the fuel tank. It also shows if the
Active Fuel Management is active
and in V4 mode, or inactive and in
V8 mode. See Active Fuel
Management 0 214 .
The Instantaneous Fuel Economy
display shows the current fuel
economy in either liters per
100 kilometers (L/100 km) or miles
per gallon (mpg). This number
reflects only the approximate fuel
economy that the vehicle has right
now and changes frequently as
driving conditions change.
Timer and Fuel Used : Can be

liters (L) or gallons (gal) of fuel used
since the last reset of this
menu item.
Oil Life : Shows an estimate of the
oil's remaining useful life.
If REMAINING OIL LIFE 99% is
displayed, that means 99% of the
current oil life remains.
When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display.
The oil should be changed as soon
as possible. See Engine Oil 0 283 .
In addition to the engine oil life
system monitoring the oil life,
additional maintenance is
recommended in the Maintenance
Schedule. See Maintenance

Driving and Operating 209
Starting the Engine Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. To restart the
engine when the vehicle is already
moving, use N (Neutral) only.
CautionDo not try to shift to P (Park) if the
vehicle is moving. If you do, you
could damage the transmission.
Shift to P (Park) only when the
vehicle is stopped.
Caution
If you add electrical parts or
accessories, you could change
the way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty.
See Add-On Electrical Equipment
0 274 . Starting Procedure (Key
Access) 1. With your foot off the
accelerator pedal, turn the
ignition key to START. When
the engine starts, let go of the
key. The idle speed will go
down as the engine gets warm.
Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently to allow the
oil to warm up and lubricate all
moving parts.
When the low fuel warning
lamp is on and the FUEL
LEVEL LOW message is
displayed in the Driver
Information Center (DIC), hold
the ignition switch in the
START position to continue
engine cranking.
Caution
Cranking the engine for long
periods of time, by returning the
ignition to the START position
(Continued) Caution (Continued) immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start
after five to 10 seconds,
especially in very cold weather
(below − 18 °C or 0 °F), it could
be flooded with too much
gasoline. Try pushing the
accelerator pedal all the way to
the floor and holding it there
while holding the key in START
for up to 15 seconds. Wait at
least 15 seconds between each
try, to allow the cranking motor
to cool down. When the engine
starts, let go of the key and
accelerator. If the vehicle starts
briefly but then stops again, do
the same thing. This clears the
extra gasoline from the engine.
Do not race the engine
immediately after starting it.
