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

will alert you to change the 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”
under Engine Oil Messages on
page 5‑41. You should change the
oil as soon as you can. See Engine

oil life, additional maintenance is
recommended in the Maintenance
Schedule in this manual. See
Scheduled Maintenance on
page 11‑2 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,

Audio Players
CD Player
Care of the CD Player
Do not add any label to a CD.
It could get caught in the CD. If a
CD is recorded on a personal
computer and a description label is
needed, try labeling the top of the
recorded CD with a marking pen.
The use of CD lens cleaners for
CDs is not advised, due to the risk
of contaminating the lens of the CD
optics with lubricants internal to the
CD player mechanism.
Notice:If a label is added to a
CD, more than one CD is inserted
into the slot at a time, or an
attempt is made to play scratched
or damaged CDs, the CD player
could be damaged. While using
the CD player, use only CDs in
good condition without any label,
load one CD at a time, and keep the CD player and the loading slot
free of foreign materials, liquids,
and debris.
If an error displays, see
“
Messages” later in this section.Care of CDs
If playing a CD-R, the sound quality
can be reduced due to CD-R or
CD-RW quality, the method of
recording, the quality of the music
that has been recorded, and the
way the CD-R or CD-RW has been
handled. Handle them carefully.
Store CD-R(s) or CD-RW(s) in their
original cases or other protective
cases and away from direct sunlight
and dust. The CD player scans the
bottom surface of the disc. If the
surface of a CD is damaged, such
as cracked, broken, or scratched,
the CD does not play properly or not
at all. Do not touch the bottom side
of a CD while handling it; this could
damage the surface. Pick up CDs
by grasping the outer edges or the
edge of the hole and the outer edge. If the surface of a CD is soiled,
clean it with a soft, lint free cloth or
dampen a clean, soft cloth in a mild,
neutral detergent solution mixed
with water. Make sure the wiping
process starts from the center to
the edge.Inserting a CD
Insert a CD partway into the slot,
label side up. The player pulls it in
and the CD should begin playing.
Ejecting a CD
ZEJECT:
Press and release to
eject the disc. Remove the CD
when Remove Disc displays. If the
disc is not removed, after several
seconds, the disc is automatically
pulled back into the player.
Playing a CD
If the ignition or radio is turned off,
with a CD in the player, it stays in
the player. When the ignition or
radio is turned on, the CD starts
playing where it stopped, if it was
the last selected audio source.

7-20 Infotainment System
Store CD-Rs or CD-RWs in their
original cases or other protective
cases and away from direct sunlight
and dust. The CD or DVD player
scans the bottom surface of the
disc. If the surface of a disc is
damaged, such as cracked, broken,
or scratched, the disc does not play
properly or not at all. Do not touch
the bottom side of a disc while
handling it; this could damage the
surface. Pick up discs by grasping
the outer edges or the edge of the
hole and the outer edge.
If the surface of a disc is soiled,
clean it with a soft, lint‐free cloth or
dampen a clean, soft cloth in a mild,
neutral detergent solution mixed
with water. Make sure the wiping
process starts from the center to
the edge.Audio Output
Only one audio source can be heard
through the speakers at one time.
An audio source is defined as DVD
slot, CD slot, XM, FM‐AM, front
auxiliary jack, USB port, or rear
auxiliary jack.
Press the
Obutton to turn the radio
on. The radio can be heard through
all of the vehicle speakers.
Front seat passengers can listen
to the radio (AM, FM, or XM if
equipped) by pressing the BAND
button or the DVD/CD AUX button
to select CD slot, DVD slot, front
auxiliary input, USB port, or rear
auxiliary input (if available).
If a playback device is plugged
into the radio’s front auxiliary
input jack, USB port, or the rear
auxiliary jack, the front seat
passengers are able to listen
to playback from this source
through the vehicle speakers. See
“Using the Auxiliary Input Jack”
in Auxiliary Devices on page 7‑30,
or “Audio/Video (A/V) Jacks” under
Rear Seat Entertainment (RSE)
System on page 7‑35 for more
information.
In some vehicles, depending on
audio options, the rear speakers
can be muted when the RSA power
is turned on. See Rear Seat Audio
(RSA) System on page 7‑45 for
more information.
Inserting a Disc
Insert a disc partway into either slot,
label side up. The player pulls it in
and the disc should begin playing.
(Loading a disc into the system,
depending on media type and
format, ranges from 5 to 20 seconds
for a CD, and up to 30 seconds for a
DVD to begin playing.)

Driving and Operating 9-31
Notice:Do 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.
Starting Procedure
1. With your foot off the accelerator pedal, turn the ignition to START.
When the engine starts, let go of
the key. The idle speed will go
down as the engine warms.
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.
The vehicle has a
Computer-Controlled Cranking
System. This feature assists in
starting the engine and protects
components. If the ignition key is
turned to the START position,
and then released when the
engine begins cranking, the
engine will continue cranking
for a few seconds or until the vehicle starts. If the engine does
not start and the key is held in
START, cranking will be stopped
after 15 seconds to prevent
cranking motor damage. To
prevent gear damage, this
system also prevents cranking if
the engine is already running.
Engine cranking can be stopped
by turning the ignition switch
to the ACC/ACCESSORY or
LOCK/OFF position.
When the Low Fuel warning
lamp is on and the FUEL LEVEL
LOW message is displayed in
the Driver Information Center
(DIC), the Computer‐Controlled
Cranking System is disabled
to prevent possible vehicle
component damage. When this
happens, hold the ignition switch
in the START position to
continue engine cranking.
Notice: Cranking the engine for
long periods of time, by returning
the key to the START position
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 5‐10 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 as you hold the key in
START for up to a maximum
of 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, repeat these
steps. This clears the extra
gasoline from the engine.
Do not race the engine
immediately after starting it.
