Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is
inoperable.
Periodic Safety Checks You Should Make Outside
the Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect the tread and sidewall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires (including spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 69

19. Odometer / Electronic Vehicle Information Center
(EVIC) Display Area
The odometer shows the total distance the vehicle has
been driven. The trip odometer shows individual trip
mileage. Refer to “Trip Odometer Button” for additional
information.
NOTE:U.S. Federal regulations require upon transfer of
vehicle ownership, the seller certify the mileage the
vehicle has been driven. Therefore, if the odometer
reading is changed because of repair or replacement, be
sure to keep a record of the reading before and after the
service so that the correct mileage can be determined.
Vehicle Warning Messages
When the appropriate conditions exist, the following
warning messages will display in the odometer:
ECO......................Fuel Saver Indicator
Check gascap........Loose Fuel Filler Cap MessageLo tirE...................... LowTirePressure
Change Oil................ OilChange Required
noFUSE..........................Fuse Fault
On vehicles equipped with a Premium Instrument Clus-
ter, this display shows the Electronic Vehicle Information
Center (EVIC) messages when the appropriate conditions
exist. Refer to Electronic Vehicle Information Center
(EVIC) in this section for more information.
ECO (Fuel Saver Indicator) — If Equipped
The ECO indicator will illuminate when you are driving
in a fuel efficient manner and can be used to modify
driving habits in order to increase fuel economy. The
ECO display will toggle on and off depending on driving
habits and vehicle usage.
Check gascap
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“Check gascap” message will display in the odometer

As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is notoperating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.

UNDERSTANDING YOUR INSTRUMENT PANEL 165

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
23. Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON position and may stay on for
as long as four seconds.If the ABS light remains on or turns on while driving,
then the Anti-Lock portion of the brake system is not
functioning and service is required. However, the con-
ventional brake system will continue to operate normally
if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
Brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON position, have the
light inspected by an authorized dealer.
24. Low Fuel Light
This light will turn on and a single chime will
sound when the fuel level drops to 1/8 tank.
25. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system called OBD. The
OBD system monitors engine and automatic
transmission control systems. The MIL will turn on when

Engine Oil Change Indicator System
Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message
will flash in the EVIC display for approximately 10 sec-
onds after a single chime has sounded, to indicate the
next scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the
engine oil change interval may fluctuate, dependent
upon your personal driving style.
Unless reset, this message will continue to display each
time you turn the ignition switch to the ON/RUN
position. To turn off the message temporarily, press and
release the MENU button. To reset the oil change indica-
tor system (after performing the scheduled maintenance)
refer to the following procedure.

continue to operate normally if the “Brake Warning
Light” is not on.
If the “ABS Warning Light” is on, the brake system should
be serviced as soon as possible to restore the benefits of
anti-lock brakes. If the “ABS Warning Light” does not come
on when the ignition switch is turned to the ON position,
have the bulb repaired as soon as possible.
If both the “Brake Warning Light” and the “ABS Warning
Light” remain on, the ABS and EBD systems are not
functioning. Immediate repair to the ABS system is
required.
MULTI-DISPLACEMENT SYSTEM (MDS) (IF
EQUIPPED) – 5.7L ENGINE ONLY
This feature offers improved fuel economy by shutting
off four of the engine’s eight cylinders during light load
and cruise conditions. The system is automatic with no
driver inputs or additional driving skills required.NOTE:The MDS system may take some time to return
to full functionality after a battery disconnect.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system commonly referred to as ESP. This
system includes the ABS (Anti-Lock Brake System), the
TCS (Traction Control System), the BAS (Brake Assist
System), and the ESP (Electronic Stability Program).
These systems work together to enhance both vehicle
stability and control in various driving conditions.
An additional electronic brake control feature called Hill
Start Assist (HSA) is standard on manual transmission
models.
ABS (Anti-Lock Brake System) — If Equipped
This system aids the driver in maintaining vehicle control
under adverse braking conditions by controlling hydrau-
lic brake pressure. This prevents wheel lock-up to help
280 STARTING AND OPERATING

WARNING! (Continued)
•Unequal tire pressures from one side of the ve-
hicle to the other can cause the vehicle to drift to
the right or left.
•Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
Economy
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Under-inflation also increases
tire rolling resistance and results in higher fuel
consumption.
Ride Comfort and Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Over-inflation produces a jarring and uncomfortable
ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the
driver’s side “B” Pillar.
Some vehicles may have supplemental tire pressure
information for vehicle loads that are less than the
maximum loaded vehicle condition. These pressure con-
ditions will be found in the “Supplemental Tire Pressure
Information” section of this manual.
The pressure should be checked and adjusted as well as
inspected for signs of tire wear or visible damage at least
once a month. Use a good quality pocket-type gauge to
check tire pressure. Do not make a visual judgement
when determining proper inflation. Radial tires may look
properly inflated even when they are under-inflated.
298 STARTING AND OPERATING

CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when us-
ing replacement equipment that is not of the same
size, type, and/or style. Aftermarket wheels can
cause sensor damage. Do not use aftermarket tire
sealants or balance beads if your vehicle is
equipped with a TPMS, as damage to the sensors
may result.
•After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the TPM sensor.NOTE:
•The TPMS is not intended to replace normal tire care
and maintenance or to provide warning of a tire failure
or condition.
•The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
•Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
•The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the
level to trigger illumination of the “TPM Telltale
Light.”

STARTING AND OPERATING 309

CAUTION! (Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of
your vehicle and also allow extended maintenance
intervals. Do not use chemical flushes in these
components as the chemicals can damage your
engine, transmission, power steering or air condi-
tioning. Such damage is not covered by the New
Vehicle Limited Warranty. If a flush is needed
because of component malfunction, use only the
specified fluid for the flushing procedure.
Engine Oil
Checking Oil Level — 3.5L Engine
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level atregular intervals, such as every fuel stop. The best time to
check the engine oil level is about five minutes after a
fully warmed engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain
the oil level between the MIN and MAX markings on the
dipstick. Adding 1.0 qt (1.0 L) of oil when the reading is
at the MIN mark will result in a MAX reading on these
engines.
CAUTION!
Overfilling or underfilling will cause oil aeration or
loss of oil pressure. This could damage your engine.
Checking Oil Level — 5.7L Engine
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
