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 or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper 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 (if
equipped), or brake fluid leaks are suspected. The cause
should be located and corrected immediately.
114 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your
Vehicle”. Follow the warnings under the Cooling
System Pressure Cap paragraph.

IMPORTANT:
The warning / indicator lights switch on
in the instrument panel together with a dedicated mes-
sage and/or acoustic signal when applicable. These
indications are indicative and precautionary and as such
must not be considered as exhaustive and/or alternative
to the information contained in the Owner ’s Manual,
which you are advised to read carefully in all cases.
Always refer to the information in this chapter in the
event of a failure indication.
All active telltales will display first if applicable. The
system check menu may appear different based upon
equipment options and current vehicle status. Some
telltales are optional and may not appear.

Oil Pressure Warning Light
Red TelltaleLight What It Means
Oil Pressure Warning Light
This light indicates low engine oil pressure. If the light turns on while driving, stop the vehicle
and shut off the engine as soon as possible. A chime will sound when this light turns on.
Do not operate the vehicle until the cause is corrected. This light does not indicate how
much oil is in the engine. The engine oil level must be checked under the hood.

condition that activated it remains active) and can be
reviewed from the “Messages” main menu item. Ex-
amples of this message type are “Right Front Turn Signal
Lamp Out” and “Low Tire Pressure.”
•Unstored Messages
This message type is displayed indefinitely or until the
condition that activated the message is cleared. Examples
of this message type are “Turn Signal On” (if a turn signal
is left on) and “Lights On” (if driver leaves the vehicle).
• Unstored Messages Until RUN
These messages deal primarily with the Remote Start
feature. This message type is displayed until the ignition
is in the RUN state. Examples of this message type are
“Remote Start Aborted - Door Ajar” and “Press Brake
Pedal and Push Button to Start.” •
Five Second Unstored Messages
When the appropriate conditions occur, this type of
message takes control of the main display area for five
seconds and then returns to the previous screen. An
example of this message type is “Automatic High Beams
On.”
Engine Oil Life Reset
Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message
will display in the DID for five seconds 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.

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes a 1/16 of an inch (1.6 mm). When the tread is
worn to the tread wear indicators, the tire should be
replaced. Refer to “Replacement Tires” in this section for
further information.
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
•Driving style.
•
Tire pressure - Improper cold tire inflation pressures can
cause uneven wear patterns to develop across the tire
tread. These abnormal wear patterns will reduce tread
life, resulting in the need for earlier tire replacement.
• Distance driven. •
Performance tires, tires with a speed rating of V or
higher, and Summer tires typically have a reduced
tread life. Rotation of these tires per the vehicle main-
tenance schedule is highly recommended.
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have a collision resulting
in serious injury or death.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.5

Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. Check
the oil level at regular intervals, such as every fuel stop.
The best time to check the engine oil level is about five
minutes after a fully warmed up engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the
dipstick. Adding one quart of oil when the reading is at
the bottom of the SAFE zone will result in a reading at the
top of the safe zone on these engines.
CAUTION!
Overfilling or underfilling the crankcase will cause
aeration or loss of oil pressure. This could damage
your engine.
Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
Refer to the “Maintenance Schedule” for further informa-
tion.
NOTE:Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km), twelve months or
350 hours of engine run time, whichever comes first. The
350 hours of engine run or idle time is generally only a
concern for fleet customers.
