Ultrasonic Parking Assist
If available, Ultrasonic Rear Parking
Assist (URPA) uses sensors on the
rear bumper to detect objects while
parking the vehicle. URPA comes
on automatically when the shift lever
is moved into R (Reverse) and
operates at speeds less than 8 km/h
(5 mph). URPA uses audio beeps to
provide distance and system
information.
Keep the sensors on the vehicle's
rear bumper clean to ensure proper
operation.
The system can be disabled by
pressing the rear park aid disable
button located next to the radio.
SeeUltrasonic Parking Assist on
page 9‑61 for more information.
Power Outlets
The accessory power outlets can be
used to plug in electrical equipment,
such as a cell phone or MP3 player.
There are two under the climate
controls, one inside the center floor
console, one on the rear of the
center floor console and one
accessory power outlet in the rear
cargo area on the passenger side.
The accessory power outlets are
powered, even with the ignition off.
Continuing to use accessory power
outlets while the ignition is in LOCK/
OFF may cause the vehicle's
battery to run down.
SeePower Outlets on page 5‑10.
Universal Remote System
This system provides a way to
replace up to three remote control
transmitters used to activate
devices such as garage door
openers, security systems, and
home automation devices.
Read the instructions completely
before attempting to program the
transmitter. Because of the steps
involved, it may be helpful to have
another person assist with
programming the transmitter.

page 5‑57.

Delayed Locking
When locking the doors with the
power lock switch and a door or the
liftgate is open, the doors will lock
five seconds after the last door is
closed. You will hear three chimes
to signal that the delayed locking
feature is in use.
Pressing the power lock switch
twice will override the delayed
locking feature and immediately lock
all the doors.
This feature will not operate if the
key is in the ignition.
You can program this feature using
the Driver Information Center (DIC).
See“Delay Door Lock” under
Vehicle Personalization (With DIC
Buttons) on page 5‑49.
Automatic Door Locks
The vehicle may have an automatic
lock/unlock feature. This feature can
be programmed using the Driver
Information Center (DIC). See Vehicle Personalization (With DIC
Buttons) on page 5‑49
for more
information on DIC programming.
Lockout Protection
If the driver side power door lock
switch is pressed when the driver
door is open and the key is in the
ignition, all of the doors will lock and
then the driver door will unlock.
If the passenger side power door
lock switch is pressed when the
front passenger door is open and
the key is in the ignition, all of the
doors will lock and then the front
passenger door will unlock.
Safety Locks
The vehicle has rear door security
locks to prevent passengers from
opening the rear doors from the
inside.
Open the rear doors to access the
security locks on the inside edge of
each door.
To set the locks, insert a key into
the slot and turn it to the horizontal
position. The door can only be
opened from the outside with the
door unlocked. To return the door to
normal operation, turn the slot to the
vertical position.

Power Assist Steps
The vehicle may have power assist
steps.
The switch used to disable the
power assist steps is located on the
center console below the climate
control system.
The power assist steps
automatically extend from beneath
the vehicle on the side in which the
door has been opened. Once the
door is closed, the assist steps
automatically move back under the
vehicle after a brief delay. The
vehicle must not be moving for the
assist steps to extend or retract.
The assist steps cannot be disabled
in the extended position.
Vehicle Security
This vehicle has theft-deterrent
features; however, they do not make
it impossible to steal.
Anti-Theft Alarm System
Your vehicle has a content
theft-deterrent alarm system.
This is the security light.
To arm the theft-deterrent system:
1. Open the door.
2. Lock the door with the RemoteKeyless Entry (RKE) transmitter
or the power door lock switch.
The security light will come on to
inform the driver the system is arming. If a door is open when
the doors are locked, the
security light will flash.
If the delayed locking feature is
turned on, the theft‐deterrent
system will not start the arming
process until the last door is
closed and the delay timer has
expired. See
Delayed Locking
on page 2‑9.
3. Close all doors. The security light should go off after about
30 seconds. The alarm is not
armed until the security light
goes off.
If a locked driver door is opened
without using the RKE transmitter, a
10-second pre-alarm will occur. The
horn will chirp and the lights will
flash. If the key is not placed in the
ignition and turned to START or the
door is not unlocked by pressing the
unlock button on the RKE
transmitter during the 10-second
pre-alarm, the alarm will go off. Your
vehicle's headlamps will flash and

Black plate (15,1)Chevrolet Tahoe/Suburban Owner Manual - 2011
Keys, Doors and Windows 2-15
the horn will sound for about
30 seconds, then will turn off to save
the battery power.
The theft-deterrent system will not
activate if the doors are locked with
the vehicle's key or the manual door
lock. It activates only if you use the
power door lock switch with the door
open or the RKE transmitter. You
should also remember that you can
start your vehicle with the correct
ignition key if the alarm has been
set off.
To avoid setting off the alarm by
accident:
.If you do not want to activate the
theft-deterrent system, the
vehicle should be locked with
the door key after the doors are
closed.
.Always unlock the doors with the
RKE transmitter. Unlocking a
door any other way will set off
the alarm if it is armed.If you set off the alarm by accident,
press unlock on the RKE transmitter
or place the key in the ignition and
turn it to START to turn off the
alarm. The alarm will not stop if you
try to unlock a door any other way.
Testing the Alarm
To test the alarm:
1. From inside the vehicle, lower
the driver window and open the
driver door.
2. Activate the system by locking the doors with the power door
lock switch while the door is
open, or with the RKE
transmitter.
3. Get out of the vehicle, close the door and wait for the security
light to go out. 4. Then reach in through the
window, unlock the door with the
manual door lock and open the
door. This should set off the
alarm.
While the alarm is set, the power
door unlock switch will not work.
If the alarm does not sound when it
should but the headlamps flash,
check to see if the horn works. The
horn fuse may be blown. To replace
the fuse, see Fuses and Circuit
Breakers on page 10‑41.
If the alarm does not sound or the
headlamps do not flash, the vehicle
should be serviced by your dealer.

Communications Commission (FCC)
rules and Industry Canada
Standards RSS-210/220/310.
Immobilizer Operation
This vehicle has PASS-Key®III+
(Personalized Automotive Security
System) theft-deterrent system.
PASS-Key III+ is a passive
theft-deterrent system.
The system is automatically armed
when the key is removed from the
ignition.
The system is automatically
disarmed when the key is turned to
ON/RUN, ACC/ACCESSORY,
or START from the LOCK/OFF
position. You do not have to manually arm or
disarm the system.
The security light will come on if
there is a problem with arming or
disarming the theft-deterrent
system.
When the PASS-Key III+ system
senses that someone is using the
wrong key, it prevents the vehicle
from starting. Anyone using a
trial-and-error method to start the
vehicle will be discouraged because
of the high number of electrical key
codes.
If the engine does not start and the
security light on the instrument
panel cluster comes on when trying
to start the vehicle, there may be a
problem with the theft-deterrent
system. Turn the ignition off and try
again.
If the engine still does not start, and
the key appears to be undamaged,
try another ignition key. At this time,
you may also want to check the
fuse. See
Fuses and Circuit
Breakers on page 10‑41. If the
engine still does not start with the
other key, the vehicle needs service.
If the vehicle does start, the first key
may be faulty. See your dealer who
can service the PASS-Key III+ to
have a new key made.
It is possible for the PASS-Key III+
decoder to learn the transponder
value of a new or replacement key.
Up to 10 keys may be programmed
for the vehicle. The following
procedure is for programming
additional keys only. If all the
currently programmed keys are lost
or do not operate, you must see
your dealer or a locksmith who can
service PASS-Key III+ to have keys
made and programmed to the
system.

Black plate (17,1)Chevrolet Tahoe/Suburban Owner Manual - 2011
Keys, Doors and Windows 2-17
See your dealer or a locksmith who
can service PASS-Key III+ to get a
new key blank cut exactly as the
ignition key that operates the
system.
To program the new additional key:
1. Verify that the new key has a
1
stamped on it.
2. Insert the original, already programmed key in the ignition
and start the engine. If the
engine will not start, see your
dealer for service.
3. After the engine has started, turn the key to LOCK/OFF, and
remove the key. 4. Insert the new key to be
programmed and turn it to the
ON/RUN position within
five seconds of turning the
ignition to the LOCK/OFF
position in Step 3.
The security light will turn off
once the key has been
programmed.
5. Repeat Steps 1 through 4 if additional keys are to be
programmed.
If you lose or damage your
PASS-Key III+ key, see your dealer
or a locksmith who can service
PASS-Key III+ to have a new
key made.
Do not leave the key or device that
disarms or deactivates the
theft-deterrent system in the vehicle.
Exterior Mirrors
Convex Mirrors
{WARNING
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you
cut too sharply into the right lane,
you could hit a vehicle on the
right. Check the inside mirror or
glance over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from
the driver seat.
