park assist CHEVROLET TAHOE 2007 3.G Owners Manual

Key In the Ignition
Never leave your vehicle with the keys inside, as it
is an easy target for joy riders or thieves. If you
leave the key in the ignition and park your vehicle, a
chime will sound, when you open the driver’s door.
Always remember to remove your key from the
ignition and take it with you. This will lock your
ignition and transmission. Also, always remember
to lock the doors.
The battery could be drained if you leave the key in
the ignition while your vehicle is parked. You may
not be able to start your vehicle after it has been
parked for an extended period of time.
Retained Accessory Power (RAP)
Your vehicle has a Retained Accessory Power
(RAP) feature which will allow certain features on
your vehicle to continue to work up to 10 minutes
after the ignition key is turned to LOCK.
The radio, power windows, and if the vehicle has a
sunroof and the OnStar
®System, will work when
the ignition key is in RUN or ACCESSORY. Once
the key is turned from RUN to LOCK, the windows
and sunroof will continue to work until a door is
opened. The radio will continue to work for up to
10 minutes or until the driver’s door is opened.
Starting the Engine
To place the transmission in the proper gear:
Move your shift lever to PARK (P) or
NEUTRAL (N). Your engine will not start in
any other position -- this is a safety feature. To
restart when you are already moving, use
NEUTRAL (N) only.
Starting Procedure
1. With your foot off the accelerator pedal, turn
the ignition key to START. When the engine
starts, let go of the key. The idle speed will go
down as your engine gets warm. Do not
race the engine immediately after starting it.
Operate the engine and transmission gently to
allow the oil to warm up and lubricate all
moving parts.
Your vehicle has a Computer-Controlled
Cranking System. This feature assists
in starting the engine and protects
components. If the ignition key is turned to the
START position, and then released when
the engine begins cranking, the engine
will continue cranking for a few seconds or
until the vehicle starts.

Turn Signal Indicator
Your vehicle may have a turn signal indicator on
the mirror. An arrow on the mirror will ash in
the direction of the turn or lane change.
Ground Illumination Lamps
The mirrors may also include ground illumination
lamps in the base of the mirror. These lamps
help you see the area near the base of the front
doors when it is dark out.
Outside Automatic Dimming Mirror
If your vehicle is equipped with this feature,
the driver’s outside mirror will adjust for the glare
of headlamps behind you. This feature is
controlled by the on and off settings found on the
electrochromic inside mirror. SeeAutomatic
Dimming Rearview Mirror with OnStar
®, Compass
and Temperature Display on page 162or
Automatic Dimming Rearview Mirror with Compass
and Temperature Display on page 166for more
information.
Outside Curb View Assist Mirrors
If your vehicle has the memory package, the
outside mirrors are able to perform the curb view
assist mirror function. This feature may be
useful in in allowing the driver to view the curb
when parallel parking. This feature will cause the
passenger’s and/or driver’s mirror to tilt to a
preselected position when the vehicle is in
REVERSE (R).
The passenger’s and/or driver’s mirror will return to
its original position when the vehicle is shifted out of
REVERSE (R) and either a thirty second delay has
occurred, the vehicle speed is greater than 8 mph
(12 km/h), or the ignition is turned to off.
This feature can be turned on or off through the
Driver Information Center (DIC). SeeDriver
Information Center (DIC) on page 260for more
information.
172

Do not use this system with any garage door
opener that does not have the stop and reverse
feature. This includes any garage door opener
model manufactured before April 1, 1982.
Read the instructions completely before attempting
to program the transmitter. Because of the steps
involved, it may be helpful to have another
person available to assist you in programming the
transmitter.
Be sure to keep the original remote control
transmitter for use in other vehicles, as well as, for
future programming. You only need the original
remote control transmitter for Fixed Code
programming. It is also recommended that upon
the sale or lease termination of the vehicle,
the programmed buttons should be erased for
security purposes. See “Erasing Universal Home
Remote Buttons” later in this section.When programming a garage door, it is advised to
park outside of the garage. Be sure that people
and objects are clear of the garage door or
security device you are programming.
Programming Universal Home
Remote — Rolling Code
Most garage door openers sold after 1996 are
Rolling Code units.
Programming a garage door opener involves
time-sensitive actions, so read the entire procedure
before you begin. If you do not follow these
actions, the device will time out and you will have
to repeat the procedure.

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.
224

The ultrasonic sensors are not kept clean. So,
be sure to keep your vehicle’s rear bumper
free of mud, dirt, snow, ice, and slush.
For cleaning instructions, seeWashing Your
Vehicle on page 557. If the DIC still displays
the PARKING ASSIST OFF message
after cleaning the bumper and driving forward
at a speed of at least 15 mph (25 km/h),
see your dealer.
Other conditions that may affect system
performance include vibrations from a
jackhammer or the compression of air brakes
on a very large truck or other mechanical
devices that interfere with URPA performance.
When URPA is disabled without driver
action and the driver attempts to turn URPA
back on by pressing the rear park aid
button, the indicator light will ash for
3 seconds and then stay lit to indicate that
URPA is off.
As always, drivers should use care when backing
up a vehicle. Always look behind you, being
sure to check for other vehicles, obstructions and
blind spots.For Driver Information Center messages related to
URPA, seeDIC Warnings and Messages on
page 270.
If the vehicle bumper is damaged, the URPA
system may not work properly. Take the vehicle to
your dealer to repair the system.
Accessory Power Outlet(s)
Accessory power outlets can be used to
connect auxiliary electrical equipment, such as a
cellular telephone or CB radio. The outlet can
accept electrical equipment up to a maximum of
20 amperes.
There are four accessory power outlets. There are
two under the climate controls, one on the back
of the oor console and a additional accessory
power outlet in the rear cargo area on the
passenger side.
225

LEFT REAR DOOR OPEN
