Charging System Light
The charging system light comes on
briefly when the ignition is turned
on, but the engine is not running, as
a check to show the light is working.
The light turns off when the engine
is started. If it does not, have the
vehicle serviced by your dealer.
If the light stays on, or comes on
while driving, there may be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the battery.
When this light comes on, the Driver
Information Center (DIC) also
displays a message.See
Battery Voltage and Charging
Messages on page 5‑31.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio
and air conditioner.
Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors the operation
of the vehicle to ensure emissions
are at acceptable levels, to produce
a cleaner environment. This light
comes on when the vehicle is
placed in ON/RUN as a check to
show it is working. If it does not,
have the vehicle serviced by your
dealer. See Ignition Positions (Key
Access) on page 9‑16 orIgnition
Positions (Keyless Access) on
page 9‑18 for more information.
This light should come on when the
ignition is on, but the engine is not
running, as a check to show it is
working. If it does not, have the
vehicle serviced by your dealer.
If the malfunction indicator lamp
comes on and stays on while the
engine is running, this indicates that
there is an OBD II problem and
service is required.

6-8 Lighting
Exit Lighting
The headlamps, taillamps, parking
lamps, back‐up lamps, and license
plate lamps come on at night, or in
areas with limited lighting, when the
key is removed from the ignition.
The dome lamps also come on
when the key is removed from the
ignition. The exterior lights and
dome lamps remain on after the
door is closed for a set amount of
time, then automatically turn off.
For vehicles with keyless access,
the exterior lights and dome lamps
automatically turn on when a door is
opened after the ignition is turned
off. SeeIgnition Positions (Key
Access) on page 9‑16 orIgnition
Positions (Keyless Access) on
page 9‑18.
The exterior lights turn off
immediately by turning the
exterior lamps control off.
This feature can be changed.
See Vehicle Personalization on
page 5‑46.
Parade Dimming
This feature does not let the
instrument panel backlight dim
during daylight hours while the key
is in the ignition and the headlamps
are on. Parade dimming
automatically works with the light
sensor, located on top of the
dashboard. If it is dark enough
outside and the parking lamps are
on, the backlight on the instrument
panel can be adjusted by turning the
instrument panel brightness knob
clockwise or counterclockwise to
brighten or dim the lighting. See
Instrument Panel Illumination
Control on page 6‑7.
Battery Load
Management
The vehicle has Electric Power
Management (EPM) that estimates
the battery's temperature and state
of charge. It then adjusts the voltage
for best performance and extended
life of the battery. When the battery's state of charge
is low, the voltage is raised slightly
to quickly bring the charge back up.
When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. If the vehicle
has a voltmeter gauge or a voltage
display on the Driver Information
Center (DIC), you may see the
voltage move up or down. This is
normal. If there is a problem, an
alert will be displayed.
The battery can be discharged at
idle if the electrical loads are very
high. This is true for all vehicles.
This is because the generator
(alternator) may not be spinning fast
enough at idle to produce all the
power that is needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, fog
lamps, rear window defogger,
climate control fan at high speed,
heated seats, engine cooling fans,
trailer loads, and loads plugged into
accessory power outlets.

automatically be powered off and
will not charge or draw power from
the vehicle's battery.
A standard iPod USB cable, like the
one that came with the iPod, cannot
be used to connect an iPod to the
vehicle. The special iPod
connection cable that came
equipped with the vehicle or that
was made available from your
dealer must be used to command
and control an iPod.
Use a standard 3.5 mm (1/8 in)
stereo cable to connect an older
iPod model that is not supported,
or if the special iPod connection
cable is missing. Command and
control of the iPod using the
infotainment control buttons and
knobs is not supported when only a
3.5 mm (1/8 in) stereo cable is used.Commanding and Controlling
an iPod
An iPod can be controlled by using
the radio buttons and knobs; the
song information shows on the
infotainment system's display. To
connect and control the iPod using
the radio controls, use the special
iPod connection cable that came as
standard equipment with the vehicle
as part of the USB option. The
special iPod connection cable can
also be purchased or made
available from your dealer. See
your dealer for more information.
Use the MENU/SELECT knob to
bring up the iPod Menu and select
Songs, Artists, Albums, Playlists,
and Audio Books to play from
the iPod.
Disconnecting an iPod
To properly dismount the iPod USB
device before disconnecting from
the vehicle, press the softkey under
the EJECT tab on the infotainment
display screen during iPod
playback.Phone
Bluetooth
For vehicles equipped with
Bluetooth capability, the system
can interact with many cell phones,
allowing:
.Placement and receipt of calls in
a hands-free mode.
.Sharing of the cell phone’s
address book or contact list with
the vehicle.
To minimize driver distraction,
before driving, and with the vehicle
parked:
.Become familiar with the
features of the cell phone.
Organize the phone book and
contact lists clearly and delete
duplicate or rarely used entries.
If possible, program speed dial
or other shortcuts.
.Review the controls and
operation of the infotainment
system.

9-18 Driving and Operating
C (ON/RUN):This position is for
driving. It is the position the ignition
switch returns to after the engine
starts, and the key is released. This
position can also be used for
service and diagnostics, and to
verify the proper operation of the
malfunction indicator lamp as may
be required for emission inspection
purposes.
To shift the transmission out of
P (Park), the ignition key has to be
in ACC/ACCESSORY or ON/RUN.
The battery could be drained if the
key is left in the ACC/ACCESSORY
or ON/RUN position with the engine
off. The vehicle might not start if the
battery is allowed to drain for an
extended period of time.
D (START): This position starts the
engine. When the engine starts,
release the key. The ignition switch
returns to ON/RUN for driving.
A warning tone will sound when the
driver door is opened, the ignition is
in ACC/ACCESSORY or LOCK/
OFF, and the key is in the ignition.Key Lock Release
Vehicles with an automatic
transmission are equipped with an
electronic key lock release system.
The key lock release is designed to
prevent ignition key removal unless
the shift lever is in P (Park).
The key lock release is always
functional except in the case of an
uncharged or low voltage (less than
9‐volt) battery. If the vehicle has an
uncharged battery or a battery with low voltage, try charging or jump
starting the battery. See
Jump
Starting on page 10‑104.
If charging or jump starting the
battery does not work, locate the
hole below the ignition lock. Insert a
flat bladed tool or another key from
the key chain into the opening.
When the lever can be felt, actuate
the lever away from the driver, and
remove the key from the ignition.
Ignition Positions
(Keyless Access)
The ignition control knob can be
turned to four different positions.
To shift out of P (Park), the ignition
must be in ON/RUN or ACC/

in order for the ignition control knob
to turn. The transmitter can be
authenticated either by putting your
foot on the brake pedal or by
pushing the ignition control knob in.
Automatic Transmission
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.
If the vehicle has the keyless
access system, your foot must be
on the brake pedal to start the
engine. To rotate the ignition control
knob, put your foot on the brake
pedal and turn the ignition control
knob to the START position. If the ignition control knob does not turn,
try pushing the knob in and turning
again. When the engine begins
cranking, let go of the ignition
control knob, it will return to the ON/
RUN position.
If the transmitter is not in the vehicle
or something is interfering with the
transmitter, the Driver Information
Center (DIC) will display
ELECTRONIC KEY NOT
DETECTED. See
Driver Information
Center (DIC) on page 5‑27 for more
