2007 CHEVROLET SUBURBAN Owners Manual

Automatic Headlamp System
When it is dark enough outside, the automatic
headlamp system will turn on the headlamps at the
normal brightness, along with the taillamps,
sidemarker, parking 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 transaxle 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 in the defroster grille
that regulates when the automatic headlamps turn
on. Be sure it is not covered, or the headlamps
will come 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 detects a change
in lighting lasting longer than the delay.
If you start your vehicle in a dark garage, the
automatic headlamp system will come on
immediately. Once you leave the garage, it will
take approximately one minute for the automatic
headlamp system to change to DRL if it is
bright enough outside. During that delay, your
instrument panel cluster may not be as bright as
usual. Make sure your instrument panel brightness
control is in the full bright position. SeeInstrument
Panel Brightness on page 219.
Your headlamps will also stay on after you exit the
vehicle. You can program this feature using the
Driver Information Center (DIC). SeeDIC Vehicle
Customization (With DIC Buttons) on page 280.
As with any vehicle, you should turn on the regular
headlamp system when needed.
217

Fog Lamps
-(Fog Lamps):If your vehicle has fog lamps,
the button is located on the instrument panel
to the left of the steering column and below the
dome lamp override button.
The ignition must be in RUN and the parking
lamps must be on for the fog lamps to work.
To turn the fog lamps on, press the fog lamps
button. A light comes on in the instrument
panel cluster to let you know that the fog lamps
are on. Press the button again to turn the fog
lamps off.
When the fog lamps are turned on, the low-beam
headlamps automatically turn on.
The fog lamps turn off while you change to
high-beam headlamps. When the high-beam
headlamps go off, the fog lamps will come
on again.
Fog lamps should only be used in foggy conditions
since they could be distracting to oncoming
drivers in clear weather conditions.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
Auxiliary Roof Mounted Lamp
If your vehicle has this feature, this button includes
wiring provisions for a dealer or a qualied
service center to install an auxiliary roof lamp.
This button is located
on the overhead
console.
When the wiring is connected to an auxiliary roof
mounted lamp, pressing the bottom of the
button will activate the lamp and illuminate an
indicator light at the bottom of this button. Pressing
the top of the button will turn off the roof mounted
lamp and indicator.
The emergency roof lamp circuit is fused at
30 amps, so the total current draw of the attached
lamps should be less than this value. The
attachment points for the roof lamp circuits are
two blunt cut wires located above the overhead
console, a dark green switched power wire and a
black ground wire.
218

For further information on roof mount emergency
lamp installation, please visit the GM Uptter
website at www.gmuptters.com or contact your
dealer.
If your vehicle has this button, your vehicle may
have the snow plow prep package. For further
information seeAdding a Snow Plow or Similar
Equipment on page 412.
Instrument Panel Brightness
D(Instrument Panel Brightness):This feature
controls the brightness of the instrument panel
lights.
The knob for this feature is located next to the
headlamp control.
Turn the knob clockwise or counterclockwise to
adjust the brightness of the instrument panel lights.
Turn the knob clockwise to return the instrument
panel cluster or radio display to full brightness
when the headlamps or parking lamps are on. To
turn on the dome lamps, turn the knob to the
farthest clockwise position.
Dome Lamps
The dome lamps come on when a door is opened.
The dome lamps can also be turned on by
turning the knob, located next to the exterior lamps
control, clockwise to the farthest position. In this
position, the dome lamps will remain on whether a
door is opened or closed.
Dome Lamp Override
E(Dome Lamp Override):Press the dome
override button, located next to the exterior lamps
control, to keep the dome lamps off when a
door is open. To set the lamps to the automatic
operation, press the button again so that it is
extended. With the button in this position,
the dome lamps will come on when a door is
opened.
219

Entry Lighting
Your vehicle has an illuminated entry feature.
When the doors are opened, the dome lamps will
come on if the dome override button is in the
extended position. If the dome override button is
pressed in, the lamps will not come on.
Exit Lighting
With exit lighting, the interior lamps will come on
when the key is removed from the ignition. They
will turn off automatically in 20 seconds. The lights
will not come on if the dome override button is
pressed in.
Reading Lamps
If your vehicle has reading lamps they are located
on the overhead console.
To turn on the reading lamps, press the button
located next to each lamp. To turn them off, press
the button again.Your vehicle may also have reading lamps in other
locations. To turn the lamps on or off, press the
button located next to the lamp.
The lamps are xed and cannot be adjusted.
Electric Power 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 put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or 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.
220

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 loads are on: 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.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It
can increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action may
be noticeable to the driver. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active or Service
Battery Charging System. If this message is
displayed, it is recommended that the driver
reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 270.
Battery Run-Down Protection
This feature shuts off the dome, and reading
lamps if they are left on for more than 10 minutes
when the ignition is off. This will keep the
battery from running down.
221

Ultrasonic Rear Parking
Assist (URPA)
If your vehicle has the Ultrasonic Rear Parking
Assist (URPA) system it is designed to help
you park while in Reverse (R). It operates only at
speeds less than 5 mph (8 km/h). URPA helps
make parking easier and helps you avoid colliding
with objects such as parked vehicles. The
URPA system detects objects that are close to the
rear of the vehicle which are at least 10 inches
(25.4 cm) off the ground and below hood or trunk
level. The system detects objects up to 8 feet
(2.5 m) behind your vehicle. The URPA sensors
determine how close these objects are from
your bumper within this area.
{CAUTION:
The Ultrasonic Rear Park Assist (URPA)
system does not replace driver vision.
URPA does not:
Operate above speeds of
5 mph (8 km/h).
Detect objects more than 8 feet
(2.5 meters) behind the vehicle. This
distance may be less during warmer
or humid weather.
Detect objects that are below the
bumper, underneath the vehicle, or
that are very close to the vehicle.
Detect children, pedestrians,
bicyclists, or pets.
So if you do not use proper care before
backing up, you could hit a vehicle, child,
pedestrian, bicyclist, or pet, resulting in
vehicle damage, injury, or death. Even
though the vehicle has the URPA system,
always check carefully before backing up
by checking behind your vehicle.
222

The URPA display is
located near the
passenger side rear
window and can
be seen by looking over
your right shoulder.
The URPA display has three color-coded lights.
The lights are used to provide distance and system
information, along with beeps that will be heard
through the speakers.
URPA can be turned off
by pressing the rear park
aid disable button
located next to the radio.
The indicator light will
come on to indicate that
URPA is off.The red light in the URPA display will also be lit if
the vehicle is in REVERSE (R). If the vehicle
has a Driver Information Center (DIC), PARKING
ASSIST OFF will display on the screen. URPA
automatically turns back on each time the vehicle
is started.
How the System Works
When the shift lever is moved into REVERSE (R),
the rear display will briey come on to let you
know the display is operating correctly. URPA
comes on automatically when the shift lever
is moved into REVERSE (R).
The system does not work at a reverse speed
greater than 5 mph (8 km/h). To remind you of this,
the red light on the rear display will ash.
223

How the System Works when Backing
If the shift lever is in REVERSE (R), URPA detects
objects close to the rear bumper. The rst time an
object is detected a single beep will sound. If an
object is detected at a REVERSE (R) speed
between 0 mph (0 km/h) and 5 mph (8 km/h), the
following describes what will occur based on your
distance to a detected object located behind the
vehicle:
At distances between 40 inches (1 m) and
8 ft (2.5 m), a single amber light will come on.
At distances between 23 inches (0.6 m) and
40 inches (1 m), both amber lights will be on.
At distances between 12 inches (0.3 m) and
23 inches (0.6 m), all three lights (amber/
amber/red) will be on.
At distances less than 12 inches (0.3 m), a
beeping sound will repeat for a short time and
all three lights (amber/amber/red) will ash.
When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a
temporary condition, the message PARKING
ASSIST OFF will be displayed on the DIC screen
and a red light will come on the URPA display
when the shift lever is moved into REVERSE (R).
This occurs under the following conditions:
The driver disables the system.
The parking brake pedal is depressed.
A trailer was attached to your vehicle, or a
bicycle or an object was hanging out of
your trunk during your last drive when you
turned off the vehicle. If the attached objects
are removed from your vehicle before the start
of your next drive, the system will return to
normal operation unless an object is detected
when the vehicle is shifted into REVERSE
(R). If this occurs, URPA assumes the object
is still attached, so you will have to wait
until the vehicle is driven forward above
15 mph (25 km/h) before URPA will return to
normal operation.
