level sensor CHEVROLET UPLANDER 2007 1.G Owners Manual

In addition, your vehicle has “dual stage” frontal
airbags, which adjust the restraint according to
crash severity. For moderate frontal impacts, these
airbags inate at a level less than full deployment.
Your vehicle has electronic frontal sensors, which
help the sensing system distinguish between a
moderate frontal impact and a more severe frontal
impact. For more severe frontal impacts, full
deployment occurs. If the front of your vehicle goes
straight into a wall that does not move or deform,
the threshold level for the reduced deployment is
about 12 to 18 mph (19 to 29 km/h), and the
threshold level for a full deployment is about 18 to
25 mph (29 to 40.2 km/h). The threshold level can
vary, however, with specic vehicle design, so that
it can be somewhat above or below this range.Frontal airbags may inate at different crash
speeds. For example:
If the vehicle hits a stationary object, the
airbags could inate at a different crash speed
than if the vehicle hits a moving object.
If the vehicle hits an object that deforms, the
airbags could inate at a different crash
speed than if the vehicle hits an object that
does not deform.
If the vehicle hits a narrow object (like a pole),
the airbags could inate at a different crash
speed than if the vehicle hits a wide object
(like a wall).
If the vehicle goes into an object at an angle,
the airbags could inate at a different crash
speed than if the vehicle goes straight into the
object.
The frontal airbags (driver and right front
passenger) are not intended to inate during
vehicle rollovers, rear impacts, or in many side
impacts.

URPA can be turned off
by pressing the rear
park aid disable switch
located in the
overhead console
switchbank.
While the system is disabled, an indicator light will
be lit on the switch. You will not see any lights
on the rear display if the switch is in the off
position.
How the System Works
Unless disabled, the URPA will turn on
automatically when the shift lever is moved into
REVERSE (R). When the system turns on,
the three lights on the display will illuminate for
one and a half seconds to let you know that
the system is working. If your vehicle is moving in
REVERSE (R) at a speed greater than 3 mph(5 km/h), the red light will ash to remind you that
the system does not work at speed greater
than 3 mph (5 km/h).
If an object is detected at a REVERSE (R) speed
of less than 3 mph (5 km/h), one of the following
will occur:

A chime will sound the rst time an object is
detected between 20 inches (0.5 m) and 5 feet
(1.5 m) away.
URPA cannot detect objects that are above liftgate
level. In order for the rear sensors to recognize
an object, it must be within detection range behind
the vehicle.
