service CADILLAC ESCALADE EXT 2009 3.G Service Manual

When the off-road mode is turned on, the navigation
system will show the path being traveled by the vehicle
when not on a marked road. This path will be a
simulation since the map database coverage will not
have these roads on the DVD. This path will be stored in
the navigation system’s memory, see “Previous
Destination” underDestination on page 4-23for more
information.
See “Off-Road Driving” in the Index of your vehicle’s
owner manual for more information about off-road
driving.
Traffic Options
Read the following Options descriptions to understand
how the XM NavTraffic™ operates.
XM NavTraffic™ (USA and Canada)
The vehicle’s navigation system may have (if equipped)
an XM NavTraffic™ receiver. XM NavTraffic™ is a
subscription service provided via XM™ Satellite Radio.
XM NavTraffic™ provides real-time traffic information
fully integrated to the navigation system to display
current traffic conditions for a driver’s chosen route. XM
NavTraffic™ allows drivers to make the most informed,
timesaving routing decisions.If the Traffic touch screen button is pressed or if an
attempt is made to turn on the traffic display in
the Navigation Setup Menu without a subscription, a
Caution screen displays indicating that XM traffic is not
activated.
Three types of traffic information for major roadways are
displayed on the navigation system:
Unscheduled traffic incident data, such as accidents
and disabled vehicles
Scheduled traffic incident data, such as road
construction and road closures
Traffic ow information (rate of speed data)
4-44

Traffic information is delivered to the vehicle by the
XM™ Radio satellites. XM NavTraffic™ makes it
possible for the navigation system to provide
continuously updated traffic information personalized for
a driver’s needs.
XM NavTraffic™ currently broadcasts the traffic
information for many markets nationally, and the service
may be available in more cities in the future. Visit
xmnavtraffic.com for more details on local coverage.
A service fee is required in order to receive the
XM NavTraffic™ service.

Global Positioning System (GPS)
The navigation system determines the position of the
vehicle by using satellite signals, various vehicle signals,
and map data.
At times, other interferences such as the satellite
condition, road conguration, the condition of the vehicle
and/or other circumstances can interfere with the
navigation system’s ability to determine the accurate
position of the vehicle.
The GPS shows the current position of the vehicle using
signals sent by the GPS Satellites of the United States
Department of Defense. When the vehicle is not
receiving signals from the satellites, a symbol appears
on the map screen. Refer toSymbols on page 4-16.
This system may not be available or interferences may
occur if any of the following are true:
Signals are obstructed by tall buildings, trees, large
trucks, or a tunnel.
Objects are located on the front dash of the vehicle.
Satellites are being repaired or improved.
After-market glass tinting has been applied to the
vehicle’s windshield.Notice:Do not apply after-market glass tinting to
the vehicle’s windows. Glass tinting interferes
with the system’s ability to receive GPS signals and
causes the system to malfunction. The window
might have to be replaced to correct the problem.
This would not be covered by the warranty.
For more information if the GPS is not functioning
properly, seeIf the System Needs Service on page 4-56
andProblems with Route Guidance on page 4-55.
Vehicle Positioning
At times, the position of the vehicle on the map may
be inaccurate due to one or more of the following
reasons:
Road system has changed.
Vehicle is driving on slippery road surfaces such as
in sand, gravel, and/or snow.
Vehicle is traveling on winding roads.
Vehicle is on a long straight road.
Vehicle is approaching a tall building or a large
vehicle.
Surface streets run parallel to a freeway.
Vehicle has just been transferred by a vehicle
carrier or a ferry.
4-54

Some routes may not be searched.
The route to the destination may not be shown if
there are new roads, if roads have recently
changed, or if certain roads are not listed on the
map DVD. SeeOrdering Map DVDs on page 4-56.
To recalibrate the vehicle’s position on the map, see
your dealer/retailer.
If the System Needs Service
If your system needs service and you have followed the
steps listed here and still are experiencing problems,
see your dealer/retailer for assistance.
Ordering Map DVDs
The map DVD in your vehicle is the most up-to-date
information available when your vehicle was produced.
The map DVD is updated periodically, provided that
the map information has changed.
If you have any questions about the operation of the
navigation system or the update process, contact
the GM Nav Disc Center toll-free phone number,
1-877-NAV-DISC (1-877-628-3472) or go to the center’swebsite, gmnavdisc.com. If you need any updates or a
replacement disc, because the current disc is lost,
damaged, or needs to be updated, call the GM Nav Disc

Radio Data System (RDS)
The audio system has a Radio Data System (RDS).
RDS features are available for use only on FM stations
that broadcast RDS information. With RDS, the radio
can do the following:
Receive announcements concerning local and
national emergencies
Display messages from radio stations
This system relies on receiving specic information from
these stations and only works when the information is
available. In rare cases, a radio station may broadcast
incorrect information that causes the radio features
to work improperly. If this happens, contact the radio
station.
The RDS system is always on. When information is
broadcast from the FM station that is playing, the station
name or call letters displays on the audio screen.

Antilock Brake System (ABS)
This vehicle has the Antilock Brake System (ABS), an
advanced electronic braking system that will help
prevent a braking skid.
When the engine is started and the vehicle begins to
drive away, ABS checks itself. A momentary motor
or clicking noise might be heard while this test is going
on. This is normal.
If there is a problem with
ABS, this warning light
stays on. SeeAntilock
Brake System (ABS)
Warning Light on
page 3-34.
Along with ABS, the vehicle has a Dynamic Rear
Proportioning (DRP) system. If there is a DRP problem,
both the brake and ABS warning lights come on
accompanied by a 10-second chime. The lights and
chime will come on each time the ignition is turned on
until the problem is repaired. See your dealer/retailer for
service.Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that the wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each front wheel
and at both rear wheels.
ABS can change the brake pressure to each wheel, as
required, faster than any driver could. This can help
the driver steer around the obstacle while braking hard.
As the brakes are applied, the computer keeps
receiving updates on wheel speed and controls braking
pressure accordingly.
Remember: ABS does not change the time needed to get
a foot up to the brake pedal or always decrease stopping
distance. If you get too close to the vehicle in front of you,
there will not be enough time to apply the brakes if that
vehicle suddenly slows or stops. Always leave enough
room up ahead to stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold the brake pedal
down rmly and let antilock work. The brakes might
vibrate or some noise might be heard, but this is normal.

If the system fails to turn on or activate, the StabiliTrak
light along with one of the following messages will
be displayed on the Driver Information Center (DIC):
TRACTION CONTROL OFF, SERVICE TRACTION
CONTROL, STABILITRAK OFF, SERVICE
STABILITRAK. If these DIC messages appear, make
sure the StabiliTrak system has not been turned
off using the StabiliTrak on/off button. Then turn the
steering wheel clockwise from the nine o’clock position
to the three o’clock position. If this clears the
message(s), the vehicle does not need servicing. If this
does not clear the message(s), then turn the vehicle
off, wait 15 seconds, and then turn it back on again to
reset the system. If any of these messages still
appear on the Driver Information Center (DIC), the
vehicle should be taken in for service. For more
information on the DIC messages, seeDriver
Information Center (DIC) on page 3-41.
The StabiliTrak light will
ash on the instrument
panel cluster when
the system is both on
and activated.
The system may be heard or felt while it is working; this
is normal.The traction control disable
button is located on the
instrument panel below the
climate controls.
The traction control part of StabiliTrak can be turned off
by pressing and releasing the StabiliTrak button if
both systems (traction control and StabiliTrak) were
previously on. To disable both traction control and
StabiliTrak, press and hold the button for ve seconds.
Traction control and StabiliTrak can be turned on by
pressing and releasing the StabiliTrak button if not
automatically shut off for any other reason.
When the TCS or StabiliTrak system is turned off, the
StabiliTrak light and the appropriate TCS off or
StabiliTrak off message will be displayed on the DIC to
warn the driver. The vehicle will still have brake-traction
control when traction control is off, but will not be
able to use the engine speed management system. See
“Traction Control Operation” next for more information.
When the traction control system has been turned
off, system noises may still be heard as a result of the
brake-traction control coming on.
5-7

It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn
the system off if the vehicle is stuck in sand, mud, ice or
snow, and you want to “rock” the vehicle to attempt to
free it. It may also be necessary to turn off the
system when driving in extreme off-road conditions
where high wheel spin is required. SeeIf Your Vehicle
is Stuck in Sand, Mud, Ice, or Snow on page 5-29
Traction Control Operation
The traction control system is part of the StabiliTrak
system. Traction control limits wheel spin by reducing
engine power to the wheels (engine speed
management) and by applying brakes to each individual
wheel (brake-traction control) as necessary.
The traction control system is enabled automatically
when the vehicle is started. It will activate and the
StabiliTrak light will ash if it senses that any of the
wheels are spinning or beginning to lose traction while
driving. If traction control is turned off, only the
brake-traction control portion of traction control will
work. The engine speed management will be disabled.
In this mode, engine power is not reduced automatically
and the driven wheels can spin more freely. This can
cause the brake-traction control to activate constantly.Notice:If the wheel(s) of one axle is allowed to
spin excessively while the StabiliTrak, ABS
and brake warning lights and any relevant DIC
messages are displayed, the transfer case could be
damaged. The repairs would not be covered by
the vehicle warranty. Reduce engine power and do
not spin the wheel(s) excessively while these
lights and messages are displayed.
The traction control system may activate on dry or
rough roads or under conditions such as heavy
acceleration while turning or abrupt upshifts/downshifts
of the transmission. When this happens, a reduction
in acceleration may be noticed, or a noise or vibration
may be heard. This is normal.
If cruise control is being used when the system
activates, the StabiliTrak light will ash and cruise
control will automatically disengage. Cruise control may
be reengaged when road conditions allow. See
Cruise Control on page 3-10
StabiliTrak may also turn off automatically if it
determines that a problem exists with the system. If the
problem does not clear itself after restarting the
vehicle, see your dealer/retailer for service.

Drinking and driving can be very dangerous on any road
and this is certainly true for off-road driving. At the
very time you need special alertness and driving skills,
your reexes, perceptions, and judgment can be
affected by even a small amount of alcohol. You could
have a serious — or even fatal — accident if you
drink and drive or ride with a driver who has been
drinking.
Off-roading can be great fun but has some denite
hazards. The greatest of these is the terrain itself. When
off-road driving, traffic lanes are not marked, curves
are not banked, and there are no road signs. Surfaces
can be slippery, rough, uphill, or downhill.
Avoid sharp turns and abrupt maneuvers. Failure to
operate the vehicle correctly off-road could result in loss
of vehicle control or vehicle rollover.
Off-roading involves some new skills. That is why it is
very important that you read these driving tips and
suggestions to help make off-road driving safer
and more enjoyable.Before You Go Off-Roading
Have all necessary maintenance and service
work done.
Make sure there is enough fuel, that uid levels are
where they should be, and that the spare tire is fully
inated.
Be sure to read all the information about
all-wheel-drive vehicles in this manual.
Make sure all underbody shields, if the vehicle has
them, are properly attached.
Know the local laws that apply to off-roading where
you will be driving or check with law enforcement
people in the area.
Be sure to get the necessary permission if you will
be on private land.
