warning light CHEVROLET TAHOE 2010 3.G User Guide

If you shift the transmission out of P (Park) while the
power function is in progress, the liftgate power function
will continue to completion. If you shift the transmission
out of P (Park) and accelerate before the power liftgate
latches closed, the liftgate may reverse to the open
position. Cargo could fall out of the vehicle. Always
make sure the power liftgate is closed and latched
before you drive away.
If you power open the liftgate and the liftgate support
struts have lost pressure, the lights will flash and a
chime will sound. The liftgate will stay open temporarily,
then slowly close. See your dealer for service before
using the liftgate.
Obstacle Detection Features
If the liftgate encounters an obstacle during a power
open or close cycle, a warning chime will sound and the
liftgate will automatically reverse direction to the full
closed or open position. After removing the obstruction,
the power liftgate operation can be used again. If the
liftgate encounters multiple obstacles on the same
power cycle, the power function will deactivate, and
you must manually open or close the liftgate. The
REAR ACCESS OPEN warning message in the Driver
Information Center (DIC) will indicate that the liftgate is
open. After removing the obstructions, manually open
the liftgate to the full open position or close the liftgate
to the fully closed and latched position. The liftgate will
now resume normal power operation.Your vehicle has pinch sensors located on the side
edges of the liftgate. If an object is caught between the
liftgate and the body and presses against this sensor,
the liftgate will reverse direction and open fully. The
liftgate will remain open until it is activated again or
closed manually. Do not force the liftgate open or closed
during a power cycle.
Manual Operation of Power Liftgate
To change the liftgate to manual operation, press the
switch on the overhead console to the OFF position.
With the power liftgate disabled and all of the doors
unlocked, the liftgate can be manually opened and
closed.
To open the liftgate, press the touchpad on the handle
on the outside of the liftgate, and lift the gate open. To
close the liftgate, use the pull cup to lower the liftgate
and close. The liftgate latch will power close. Always
close the liftgate before driving.
If the RKE button or the power close button on the
liftgate is pressed while power operation is disabled, the
lights will flash three times, but the liftgate will not move.
It is not recommended that you drive with the liftgate
open, however, if you must drive with the liftgate open,
the liftgate should be set to manual operation by
pressing the OFF switch on the center console.

Ignition Positions
The ignition switch has
four different positions.
To shift out of P (Park), the ignition must be in ON/RUN
or ACC/ACCESSORY and the regular brake pedal must
be applied.
A (LOCK/OFF): This position locks the ignition. It also
locks the transmission on automatic transmission
vehicles. The key can be removed in LOCK/OFF.
On vehicles with an automatic transmission, the shift
lever must be in P (Park) to turn the ignition switch to
LOCK/OFF. The steering can bind with the wheels turned off center.
If this happens, move the steering wheel from right to
left while turning the key to ACC/ACCESSORY. If this
doesn't work, then the vehicle needs service.
Notice:
Using a tool to force the key to turn in the
ignition could cause damage to the switch or break
the key. Use the correct key, make sure it is all the
way in, and turn it only with your hand. If the key
cannot be turned by hand, see your dealer.
B (ACC/ACCESSORY): This position lets things like
the radio and the windshield wipers operate while the
engine is off. Use this position if the vehicle must be
pushed or towed.
C (ON/RUN): This position can be used to operate the
electrical accessories and to display some instrument
panel cluster warning and indicator lights. The switch
stays in this position when the engine is running. The
transmission is also unlocked in this position on
automatic transmission vehicles.
If you leave the key in the ACC/ACCESSORY or
ON/RUN position with the engine off, the battery could
be drained. You may not be able to start the vehicle if
the battery is allowed to drain for an extended period
of time.

The vehicle has StabiliTrak®. Shifting into
Four-Wheel-Drive Low will turn Traction Control
and StabiliTrak
®off. See StabiliTrak®Systemon
page 5‑6.
{WARNING:
Shifting the transfer case to N (Neutral) can cause
the vehicle to roll even if the transmission is in
P (Park). You or someone else could be seriously
injured. Be sure to set the parking brake before
placing the transfer case in N (Neutral). See
Parking Brake on page 3‑46.
N (Neutral): Shift the vehicle's transfer case to

WARNING: (Continued)
If you do not use proper care before and while
backing; vehicle damage, injury, or death could
occur. Even with URPA, always check behind the
vehicle before backing up. While backing, be sure
to look for objects and check the vehicle's mirrors.
How the System Works
URPA comes on automatically when the shift lever is
moved into R (Reverse). A single tone sounds to
indicate the system is working.
URPA operates only at speeds less than
5 mph (8 km/h).
An obstacle is indicated by audible beeps. The interval
between the beeps becomes shorter as the vehicle gets
closer to the obstacle. When the distance is less than
30 cm (12 in) the beeps are continuous.
To be detected, objects must be at least 25.4 cm (10 in)
off the ground and below liftgate level. Objects must
also be within 2.5 m (8 ft) from the rear bumper. This
distance may be less during warmer or humid weather.
The system can be
disabled by pressing the
rear park aid disable
button located next to the
radio.
The indicator light will come on and PARK ASSIST OFF
displays on the Driver Information Center (DIC) to
indicate that URPA is off, see DIC Warnings and
Messages on page 4‑61.
When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a tem
porary condition, the messages PARK ASSIST OFF or
PARK ASST BLOCKED SEE OWNERS MANUAL will
be displayed on the DIC.
SERVICE PARK ASSIST: If this message occurs, take
the vehicle to your dealer to repair the system.
PARK ASSIST OFF: This message occurs if the driver
disables the system.
3-57

PARK ASST BLOCKED SEE OWNERS MANUAL:
This message can occur under the following conditions:
.The ultrasonic sensors are not clean. Keep the
vehicle's rear bumper free of mud, dirt, snow, ice
and slush. For cleaning instructions, seeWashing
Your Vehicle on page 6‑111.
.The park assist sensors are covered by frost or
ice. Frost or ice can form around and behind the
sensors and may not always be seen; this can
occur after washing the vehicle in cold weather.
The message may not clear until the frost or ice
has melted.
.A trailer was attached to the vehicle, or a bicycle
or an object was hanging out of the liftgate during
the last drive cycle. Once the attached object is
removed, URPA will return to normal operation.
.A tow bar is attached to the vehicle.
.The vehicle's bumper is damaged. Take the vehicle
to your dealer to repair the system.
.Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
If the system is still disabled, after driving forward at
least 40 km/h (25 mph), take the vehicle to your dealer.
Side Blind Zone Alert (SBZA)
The vehicle may have a Side Blind Zone Alert (SBZA)
system. Read this entire section before using the
system.
{WARNING:
SBZA is only a lane changing aid and does not
replace driver vision. SBZA does not detect:
.Vehicles outside the side blind zones which
may be rapidly approaching.
.Pedestrians, bicyclists, or animals.
Failure to use proper care when changing lanes
may result in damage to the vehicle, injury,
or death. Always check the outside and rearview
mirrors, glance over your shoulder, and use the
turn signal before changing lanes.
When the system detects a vehicle in the side blind
zone, amber SBZA displays light up in the side mirrors.
This indicates that it may be unsafe to change lanes.
3-58

Before making a lane change, always check the SBZA
display, check the outside and rearview mirrors, look
over your shoulder for vehicles and hazards, and use
the turn signal.
SBZA Detection Zones
The SBZA sensor covers a zone of approximately
one lane over from both sides of the vehicle, 3.5 m
(11 ft). This zone starts at each side mirror and goes
back approximately 5.0 m (16 ft). The height of the zone
is approximately between 0.5 m (1.5 ft) and 2.0 m (6 ft)
off the ground.Use caution while changing lanes when towing a trailer,
as the SBZA detection zones do not change when a
trailer is towed.
How the System Works
Left Side Mirror DisplayRight Side Mirror Display
When the vehicle is started, both outside mirror displays
will briefly come on to indicate that the system is
operating. When the vehicle is moving forward, the left
or right side mirror SBZA display will light up if a vehicle
is detected in that blind zone. If the turn signal is
activated and a vehicle is also detected on the same
side, the SBZA display will flash to give you extra
warning not to change lanes.
SBZA displays do not come on while the vehicle is
approaching or passing other vehicles. At speeds
greater then 32 km/h (20 mph), SBZA displays may
come on when a vehicle you have passed remains in
or drops back into the detection zone.
