SERVICE TIRE MONITOR
SYSTEM
On vehicles with the Tire Pressure
Monitor System (TPMS), this
message displays if a part on the
TPMS is not working properly.
The tire pressure light also flashes
and then remains on during the
same ignition cycle. See Tire
Pressure Light on page 5‑23.
Several conditions may cause this
message to appear. See Tire
Pressure Monitor Operation on
page 10‑46 for more information.
If the warning comes on and stays
on, there may be a problem with
the TPMS. See your dealer.
TIRE LEARNING ACTIVE
This message displays when the
Tire Pressure Monitor System
(TPMS) is relearning the tire
positions on your vehicle. The tire
positions must be relearned after
rotating the tires or after replacing a
tire or sensor. See Tire Rotation on

Transmission Messages
ALL WHEEL DRIVE OFF
If your vehicle has the All-Wheel
Drive (AWD) system, this message
displays when there is a compact
spare tire on the vehicle, when the
Antilock Brake System (ABS)
warning light comes on, or when the
rear differential fluid is overheating.
This message turns off when the
differential fluid cools. The AWD system is disabled until
the compact spare tire is replaced
by a full-size tire. If the warning
message is still on after putting on
the full-size tire, you need to reset
the warning message. To reset the
warning message, turn the ignition
off and then back on again after
30 seconds. If the message stays
on, see your dealer right away.

for the message on the DIC display.
If the message is still displayed or
appears again when you begin
driving, the AWD system needs
service. See your dealer.

Daytime Running
Lamps (DRL)/Automatic
Headlamp System
Daytime Running Lamps (DRL) can
make it easier for others to see the
front of your vehicle during the day.
Fully functional daytime running
lamps are required on all vehicles
first sold in Canada.
The DRL system makes the
low-beam headlamps come on at a
reduced brightness when the
following conditions are met:
.The ignition is in the ON/RUN
position.
.The exterior lamps control is
in AUTO.
.The engine is running.When the DRL are on, the regular
headlamps, taillamps, sidemarker,
and other lamps will not be on.
The instrument panel and cluster
will also not be lit.
The headlamps automatically
change from DRL to the regular
headlamps depending on the
darkness of the surroundings.
The other lamps that come on with
the headlamps will also come on.
When it is bright enough outside,
the headlamps will go off and the
DRL will come on.
The regular headlamp system
should be turned on when needed.
Do not cover the light sensor on top
of the instrument panel because it
works with the DRL.
Delayed Headlamps
Delayed headlamps provide a
period of exterior lighting as you
leave the area around the vehicle.
This feature is activated when
the headlamps are on due to the
automatic headlamps control
feature, and when the ignition is
turned off. The headlamps remain
on until the exterior lamps control is
moved to the parking lamps position
or until the pre-selected delayed
headlamp lighting period has ended.
If the ignition is turned off with the
exterior lamp control in the parking
lamps or headlamps position, the
delayed headlamps cycle will not
occur.
To disable the delayed headlamps
feature or change the time of
delay, see

Lighting Features
Entry Lighting
For vehicles with courtesy lamps,
they come on and stay on for a set
time whenever
Kis pressed on
the Remote Keyless Entry (RKE)
transmitter.
If a door is opened, the lamps stay
on while it is open and then turn off
automatically about 20 seconds
after the door is closed. If
Kis
pressed and no door is opened,
the lamps turn off after about
20 seconds.
Entry lighting includes a feature
called theater dimming. With theater
dimming, the lamps do not turn off
at the end of the delay time.
Instead, they slowly dim and then
go out. The delay time is canceled if
the ignition key is turned to ON/RUN
or the power door lock switch is
pressed. The lamps will dim
right away. When the ignition is on, illuminated
entry is inactive, which means the
courtesy lamps will not come on
unless a door is opened.
Delayed Entry Lighting
Delayed entry lighting illuminates
the interior for a period of time after
all the doors have been closed.
The ignition must be off for delayed
entry lighting to work. Immediately
after all the doors have been closed,
the delayed entry lighting feature
continues to work until one of the
following occurs:
.The ignition is in ON/RUN.
.The doors are locked.
.An illumination period of about
25 seconds has elapsed.
If during the illumination period a
door is opened, the timed
illumination period is canceled and
the interior lamps remain on.

Delayed Exit Lighting
Delayed exit lighting illuminates the
interior for a period of time after the
key is removed from the ignition.
The ignition must be off for delayed
exit lighting to work. When the key
is removed, interior illumination
activates and remains on until one
of the following occurs:
.The ignition is in ON/RUN.
.The power door locks are
activated.
.An illumination period of
20 seconds has elapsed.
If during the illumination period a
door is opened, the timed
illumination period will be canceled
and the interior lamps will remain on
because a door is open.
Parade Dimming
This feature automatically prohibits
the dimming of the instrument panel
displays in daylight while the
headlamps are on so that the
displays are still able to be seen.
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
of the power 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.
