Twilight Sentinel Automatic Lamp
Control (Optional, Standard in Canada)
Twilight Sentinel can turn your lamps on and off for
you. A light sensor on top of the instrument panel makes
the Twilight Sentinel work, so be sure it isn't covered.
You can customize your vehicle to turn Twilight
Sentinel on or off (except for vehicles first sold in
Canada). See ªDriver Information Center (DIC)º in the
Index to turn this feature on or off.
When Twilight Sentinel is turned on, you will see the
following happen:

When it's dark enough outside, the front turn signal
lamps (DRL) will go off, and the headlamps and
parking lamps will come on. The other lamps that
come on with headlamps will also come on.

When it's bright enough outside, the headlamps will
go off, and the front turn signal lamps (DRL) will
come on, as long as the headlamp switch is in the
OFF position.
With Twilight Sentinel turned on, you can idle the
vehicle with the lamps off, even when it's dark outside.
First set the parking brake while the ignition is in OFF.
Then start the vehicle. The lamps will stay off until you
release the parking brake.Twilight Sentinel also provides exterior illumination as
you leave the vehicle. If Twilight Sentinel has turned on
the lamps when you turn off the ignition, your lamps
will remain on until:

The headlamp switch is moved from OFF to the
parking lamp position, or

a delay time that you select has elapsed.
See ªDriver Information Center (DIC)º in the Index to
select the delay time that you want. You can also select
no delay time.
If you turn off the ignition with the headlamp switch in
the parking lamp or headlamp position, the Twilight
Sentinel delay will not occur. The lamps will turn off as
soon as the switch is turned off.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Blank Page
There is a blank page at the end of the OPTIONS menu.
When the blank page is displayed, you can access the
following items:
FOB TRAINING: This option allows you to match the
RKE transmitter(s) to your vehicle. You can access this
option by pressing and holding RESET for three
seconds while you are on the blank page at the end of
the OPTIONS menu. The message FOB TRAINING
will be displayed. See ªMatching Transmitter(s) To Your
Vehicleº in the Index for more information.
TIRE TRAINING (Except Z06): The Tire Pressure
Monitor (TPM) operates with battery
-powered sensors that
are located inside the valve stems on each tire. Each sensor
has a unique ID code so the vehicle knows the tire location
of the sensor. When the vehicle reaches a speed of greater
than 15 mph (24 km/h), the sensors begin to send the tire
pressure readings to a receiver inside the vehicle. These
readings are displayed when using the GAGES button on
the DIC. If you are unable to display your tire pressures
while the vehicle speed is greater than 15 mph (24 km/h),
you may need to have your sensor ID codes learned by the
vehicle. See your dealer.

HIGH TIRE PRESSURE - (LF, LR, RF, RR)
(Except Z06): You will hear two chimes when this
message is displayed. To acknowledge the warning,
press RESET. After you press RESET, a message will
reappear every 10 minutes until this condition changes.
This message indicates that the pressure in one of your
tires is higher than 42 psi (290 kPa). Next to the
HIGH TIRE PRESSURE message, you can see either
LF (left front), LR (left rear), RF (right front) or
RR (right rear) to indicate to you which tire is higher
than 42 psi (290 kPa). You can receive more than one
tire pressure message at a time. To read other messages
that may have been sent at the same time, press RESET.
If a tire pressure message appears on the DIC, stop as
soon as you can. Have the tire pressures checked and set
to those shown on your Tire Loading Information Label.
See ªExtended Mobility Tiresº and ªTire Inflationº in
the Index.SERVICE TIRE MON SYS (Except Z06): If this
message comes on, a part on the Tire Pressure Monitor
(TPM) is not working properly. If you drive your
vehicle while any of the four sensors are missing or
inoperable, the warning will come on in approximately
10 minutes. If all four sensors are missing, the warning
will come on in approximately 15 to 20 minutes. (All
the sensors would be missing, for example, if you put
different wheels on your vehicle without transferring the
sensors.) If the warning comes on and stays on, there
may be a problem with the TPM. See your dealer.

Operating the system in the recirculation mode may
cause fogging of the vehicle's windows when the
weather is cold and damp. To clear the fog, switch the
system to either the DEFOG or DEFROST mode and
increase the fan speed. To avoid re
-fogging of the
windows, operate the system in the OUTSIDE
AIR mode.
FRONT: Press the FRONT defrost button to
quickly remove fog or frost from the windshield. This
setting directs most of the airflow to the windshield and
a small amount toward the lower and side window
outlets. The light on the button will come on and the
digital display will show the defrost mode symbol and
fan speed when the front defrost mode is being used.
Pressing FRONT defrost again will return the system to
the last operating mode and the air intake mode will be
in OUTSIDE AIR.
If the system is in FRONT defrost when you shut the
engine off, it will restart in FRONT defrost unless the
engine is off for longer than 40 minutes. If the engine is
off longer than 40 minutes, the system will restart in the
operating mode you had set prior to FRONT defrost and
the air intake mode will be in OUTSIDE AIR.
See ªRear Window Defoggerº later in this section for
more information.
Sensors
The automatic electronic dual climate control system
uses several sensors to control operation and
display information.
Solar Load Sensor
This sensor is located on the top right side of the
defroster grille. The defroster grille is on the top of
the instrument panel.
The sensor monitors the sun's solar radiation and uses
this information as part of the automatic climate control
system when operating in the AUTO mode.
Be careful not to put anything over the sensor. When
covered, the sensor cannot compensate for changes in
the amount of heat the vehicle is absorbing from the sun.

3-10
Outside Air Temperature Sensor
This sensor is located in the air intake under the front
bumper of the vehicle. Information from this sensor
is used for the outside air temperature readings
shown on the digital display for the automatic climate
control system.
If the outside temperature goes up, the displayed
temperature will not change until:

The vehicle's speed is above 16 mph (26 km/h) for
one and a half minutes.

The vehicle's speed is above 45 mph (72 km/h) for
one minute.
These delays help prevent false readings. If the
temperature goes down, the outside temperature display
is updated immediately.
If the vehicle has been turned off for more than three
hours, the current outside temperature will be shown
when you start the vehicle. If it has been turned off for
less than three hours, the temperature will be recalled
from the previous vehicle operation.Inside Temperature Sensor
This sensor is located to the left of the ignition switch.
The automatic climate control system uses this sensor to
receive information, so if you block or cover it, the
system will not function properly.
Air Conditioning
On very hot days, the vehicle will cool down more
quickly and economically if you open the windows long
enough to let hot inside air escape. Then keep the
windows closed in order to allow the air conditioning to
work best. Maximum cooling will occur when the
recirculate setting is operating, airflow direction is in the
upper mode, and the temperature knob (on a manual
climate control system) is turned all the way to the blue
area. These settings will be selected by the automatic
electronic dual climate control system if operating in
AUTO when maximum cooling is required.
When the air conditioning is on, you may
sometimes notice slight changes in the vehicle's engine
performance and power. This is normal. The system is
designed to help fuel economy while maintaining the
desired cooling level.
The air conditioning removes moisture from the air,
so you may notice water dripping from under the
vehicle when it is idling or after it has been turned off.
This is normal.

5-21 Tire Sealant
The kit contains a liquid sealant that when injected into
a flat tire, may temporarily repair nail holes or cuts in
the tread area of the tire. The tire sealant cannot repair
tire damage caused while driving on a flat tire or a tire
that has had a ªblow outº or a tire that has punctures in
the sidewall areas. The tire sealant solution is a one
-time
use application for one tire only. Check the tire sealant
expiration date; the sealant may not be as effective
beyond the expiration date. The tire sealant can be
peeled off easily after drying.
NOTICE:
Do not use a tire sealant if your vehicle is
equipped with Extended Mobility Tires or tire
pressure monitors. The tire sealant can damage
tire pressure monitor sensors. See ªExtended
Mobility Tiresº in the Index.
Air Compressor
The air compressor included in the Tire Inflator Kit,
was designed exclusively for the Z06 Model equipped
with P295/35ZR18 and P265/40ZR17 tires. After the
sealant has been injected into the flat tire, use the air
compressor to inflate the tire to at least 26 psi (179 kPa).
Instructions for connecting and using the air compressor
are located on the air compressor.
