2008 CADILLAC ESCALADE EXT sensor

Driving with IntelliBeam®
IntelliBeam®will only activate your high-beams when
driving over 20 mph (32 km/h).
The high-beam headlamps will remain on, under the
automatic control of IntelliBeam
®, until any of the
following situations occur:
The system detects an approaching vehicle’s
headlamps.
The system detects a preceding vehicle’s taillamps.
The outside light is bright enough that high-beam
headlamps are not required.
The vehicle’s speed drops below 15 mph (24 km/h).
The headlamp stalk is moved forward to the
high-beam position. SeeHeadlamp High/Low-Beam
Changer on page 3-9.
When either of these conditions occur, the
IntelliBeam
®feature will be disabled and the
IntelliBeam®light in the mirror will turn off until the
high-beam stalk is returned to the neutral position.
If IntelliBeam®was using low-beams prior to this
action, the IntelliBeam®feature will be temporarily
disabled until the stalk is returned to the neutral
position.
The exterior lamp control is turned to any setting
except AUTO.
When this occurs, IntelliBeam
®will be disabled until
the control is turned back to the AUTO position.
The IntelliBeam®system is turned off at the inside
rearview mirror.
IntelliBeam
®may not turn off the high-beams if the
system cannot detect other vehicle’s lamps because of
any of the following:
The others vehicle’s lamp(s) are missing, damaged,
obstructed from view or otherwise undetected.
The other vehicle’s lamp(s) are covered with dirt,
snow and/or road spray.
The other vehicle’s lamp(s) cannot be detected due
to dense exhaust, smoke, fog, snow, road spray,
mist or other airborne obstructions.
Your vehicle’s windshield is dirty, cracked or
obstructed by something that blocks the view of
the IntelliBeam light sensor.
Your vehicle’s windshield is covered with ice, dirt,
haze or other obstructions.
Your vehicle is loaded such that the front end of
the vehicle points upward, causing the IntelliBeam
sensor to aim high and not detect headlamps
and taillamps.
You are driving on winding or hilly roads.

You may need to manually disable or cancel the
high-beam headlamps by turning the low-beam
headlamps on, if any of the above conditions exist.
Disabling and Resetting IntelliBeam®
at the Rearview Mirror
IntelliBeam®can be disabled by using the controls on
the inside rearview mirror.
AUTO
3(On/Off):To disable the system, press this
button on the inside rearview mirror. The IntelliBeam®
indicator will turn off and will not come back on until
the IntelliBeam®button is pressed again.
(Stalk Disable):When IntelliBeam
®has turned on
the high-beams, pull or push the high-beam stalk. This
will disable IntelliBeam
®. The IntelliBeam®indicator
on the mirror will turn off. To re-enable IntelliBeam®,
press the IntelliBeam®button on the mirror.
A different sensitivity setting is available for dealer
diagnostics. This is done by pushing and holding this
button for 20 seconds until the IntelliBeam
®indicator
light ashes three times. If you accidentally activate
this, the vehicle’s setting will automatically be reset
each time the ignition is turned off and then on again.
Cleaning the IntelliBeam®Light Sensor
The light sensor is located
on the inside of the vehicle
in front of the inside
rearview mirror.
Clean the light sensor window, periodically, using
glass cleaner on a soft cloth. Gently wipe the sensor
window. Do not spray glass cleaner directly on the
surface of the sensor window.
Headlamps on Reminder
If a door is open, a reminder chime will sound when your
headlamps or parking lamps are manually turned on and
your key is out of the ignition. To turn off the chime, turn
the headlamp switch to off or AUTO and then back on,
or close and re-open the door. In the AUTO mode, the
headlamps turn off once the ignition is in LOCK or may
remain on until the headlamp delay ends (if enabled
in the DIC). See “Exit Lighting” underDIC Vehicle
Customization on page 3-57.

Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during the day.
DRL can be helpful in many different driving conditions,
but they can be especially helpful in the short periods
after dawn and before sunset. Fully functional daytime
running lamps are required on all vehicles rst sold
in Canada.
The DRL system will come on when the following
conditions are met:
The ignition is on.
The exterior lamps control is in AUTO.
The transmission is not in PARK (P).
The light sensor determines it is daytime.
When the DRL are on, only the DRL lamps will be on.
The taillamps, sidemarker, and other lamps will not
be on. The instrument panel will not be lit up either.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
To turn off the DRL lamps, turn the exterior lamps
control to the OFF position and then release. For
vehicles rst sold in Canada, the transmission must
be in the PARK (P) position, before the DRL lamps
can be turned off.
Automatic Headlamp System
When it is dark enough outside and the headlamp switch
is in AUTO, the automatic headlamp system will turn on
the headlamps at the normal brightness along with other
lamps such as the taillamps, sidemarker, parking lamps,
roof marker lamps, and the instrument panel lights.
The radio lights will also be dim.
To turn off the automatic headlamp system, turn
the exterior lamps switch to the off position and
then release. For vehicles rst sold in Canada, the
transmission must be in the PARK (P) position, before
the automatic headlamp system can be turned off.
The vehicle has a light sensor located on the top
of the instrument panel. Be sure it is not covered,
or the system will be on whenever the ignition is on.
The system may also turn on the headlamps when
driving through a parking garage, heavy overcast
weather, or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running
Lamps (DRL) and the automatic headlamp systems
so that driving under bridges or bright overhead
street lights does not affect the system. The DRL
and automatic headlamp system will only be affected
when the light sensor sees a change in lighting
lasting longer than the delay.

Automatic Operation
AUTO (Automatic):When automatic operation is
active the system will control the inside temperature,
the air delivery, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will change to
show the current temperature(s) and AUTO will
appear. The current delivery mode and fan speed will
also be displayed for approximately ve seconds.
When AUTO is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor will
run when the outside temperature is over about
40°F (4°C). The air inlet will normally be set to
outside air. If it is hot outside, the air inlet may
automatically switch to recirculate inside air to help
quickly cool down your vehicle. The light on the
button will come on in recirculation.
2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a 74°F (23°C)
temperature setting and allow about 20 minutes
for the system to regulate. Use the driver’s or
passenger’s temperature buttons to adjust thetemperature setting as necessary. If you choose
the temperature setting of 60°F (15°C), the system
will remain at the maximum cooling setting.
If you choose the temperature setting of 90°F (32°C),
the system will remain at the maximum heat setting.
Choosing either maximum setting will not cause
the vehicle to heat or cool any faster.
Be careful not to cover the sensor located on the top
of the instrument panel near the windshield. This sensor
regulates air temperature based on sun load and also
turns on your headlamps.
To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the engine coolant
temperature. Pressing the fan switch will override
this delay and change the fan to a selected speed.
O(Off):Press the driver’s side temperature knob to
turn off the climate control system. Outside air will
still enter the vehicle, and will be directed to the oor.
This direction can be changed by pressing the mode
button. The temperature can also be adjusted using
either temperature knob. Press the up or down arrows
on the fan switch, the defrost button, the AUTO
button, driver’s side temperature knob, or the air
conditioning button to turn the system on when it is off.

Passenger Safety Belt Reminder Light
Several seconds after the engine is started, a chime
will sound for several seconds to remind the front
passenger to buckle their safety belt. This would
only occur if the passenger airbag is enabled.
SeePassenger Sensing System on page 1-65for
more information. The passenger safety belt light,
located on the instrument panel, will come on and
stay on for several seconds and then ash for
several more.
This chime and light are
repeated if the passenger
remains unbuckled and
the vehicle is in motion.
If the passenger’s safety belt is buckled, neither
the chime nor the light will come on.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel cluster, which shows the airbag symbol.
The system checks the airbag’s electrical system for
malfunctions. The light tells you if there is an electrical
problem. The system check includes the airbag
sensor, the pretensioners, the airbag modules, the
wiring and the crash sensing and diagnostic module.
For more information on the airbag system, see
Airbag System on page 1-56.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
The light should go out
and the system is ready.
If the airbag readiness light stays on after you start
the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.
3-32

There are several conditions that can cause this
message to appear.
One condition is overheating, which could occur if
StabiliTrak®activates continuously for an extended
period of time.
The message also displays if the brake system
warning light is on. SeeBrake System Warning
Light on page 3-36.
The message could display if the stability system
takes longer than usual to complete its diagnostic
checks due to driving conditions.
The message displays if an engine or vehicle
related problem has been detected and the vehicle
needs service. See your dealer/retailer.
The message turns off as soon as the conditions that
caused the message to be displayed are no longer
present.
TIGHTEN GAS CAP
This message may display along with the check engine
light on the instrument panel cluster if the vehicle’s
fuel cap is not tightened properly. SeeMalfunction
Indicator Lamp on page 3-40. Reinstall the fuel cap fully.SeeFilling the Tank on page 5-8. The diagnostic
system can determine if the fuel cap has been left
off or improperly installed. A loose or missing fuel
cap allows fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn this light and message off.
TIRE LEARNING ACTIVE
This message displays when the Tire Pressure Monitor
System (TPMS) is re-learning the tire positions on
your vehicle. The tire positions must be re-learned after
rotating the tires or after replacing a tire or sensor.
SeeTire Inspection and Rotation on page 5-68,
Tire Pressure Monitor System on page 5-63, and
Ination - Tire Pressure on page 5-61for more
information.
TRACTION CONTROL OFF
If your vehicle has StabiliTrak®, this message displays
when the Traction Control System (TCS) is turned
off. Adjust your driving accordingly. SeeStabiliTrak
®
System on page 4-6for more information.
3-56

If your vehicle has P265/65R18 or P285/45R22 size
tires and you will be driving at high speeds, speeds of
100 mph (160 km/h) or higher, set the cold ination
pressure to 3 psi (20 kPa) above the recommended tire
pressure shown on the Tire and Loading Information
Label. When you end this high-speed driving, return the
tires to the cold ination pressure shown on the Tire
and Loading Information label. SeeLoading Your
Vehicle on page 4-35andInation - Tire Pressure
on page 5-61.
Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses radio
and sensor technology to check tire pressure levels.
The TPMS sensors monitor the air pressure in
your vehicle’s tires and transmit tire pressure readings
to a receiver located in the vehicle.
Each tire, including the spare (if provided), should be
checked monthly when cold and inated to the ination
pressure recommended by the vehicle manufacturer
on the vehicle placard or tire ination pressure label.
(If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire ination
pressure label, you should determine the proper
tire ination pressure for those tires.)As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one
or more of your tires is signicantly under-inated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires as
soon as possible, and inate them to the proper
pressure. Driving on a signicantly under-inated tire
causes the tire to overheat and can lead to tire failure.
Under-ination also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-ination
has not reached the level to trigger illumination of
the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator
is combined with the low tire pressure telltale. When
the system detects a malfunction, the telltale will
ash for approximately one minute and then remain
continuously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as the
malfunction exists.
5-63

When the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may occur
for a variety of reasons, including the installation
of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your vehicle
to ensure that the replacement or alternate tires
and wheels allow the TPMS to continue to function
properly.
SeeTire Pressure Monitor Operation on page 5-64,
for additional information.
