Automatic Level Control; Rear Parking Assist; Transaxle Warm-Up Shift; Automatic Door Unlock - Oldsmobile SILHOUETTE GTK 2004 Getting To Know Manual

Automatic Level Control

Vehicles equipped with automatic level
control may experience a "whirring"
sound under the rear of the vehicle. This
is normal. Under additional rear loads
(passengers or cargo), this sound indi-
cates that the level control compressor
is working — sending additional air to
your rear shock absorbers to provide
level ride height.
See Section 4 of your Owner Manual.

Rear Parking Assist

If equipped, your vehicle's Rear Parking
Assist operates when the shift lever is
moved into reverse and vehicle speed is
less than 3 mph. The RPA can detect
objects three inches and wider, and at
least 10 inches tall. It cannot detect
objects above the rear bumper or ones
that are extremely small.
When shifting into reverse, a chime will
sound the first time an object is detect-
ed, if the object is between 20 inches
and five feet away. At five feet, the RPA
indicator lights (located near the rear
dome light) will display an amber light.
As you move closer, additional lights are
displayed and a continuous chime will
sound when you reach 20 inches or
closer.
Important: The RPA system indicator
lights will flash red if it is not functioning
properly. This condition is most likely
caused by either dirty ultrasonic sensors
(located on the rear bumper) or if your
vehicle exceeds 3 mph when backing
up. Under certain conditions, such as
towing a trailer, you may want to turn off
the rear parking assist by using the
switch on the overhead console.
See Section 3 of your Owner Manual.

Transaxle Warm-Up Shift

Your vehicle has a computer-controlled
transmission designed to warm up the
engine faster when the weather is 35
degrees F (2 degrees C) or colder. You
may notice that the transmission will
shift at a higher speed until the engine is
warmed up. This is a normal condition
designed to provide heat to the passen-
ger compartment and defrost the win-
dows more quickly.
See Section 2 of your Owner Manual.

Automatic Door Unlock

Your vehicle's power door locks have
been set at the factory to unlock after
the vehicle has been shifted into PARK
(P) and the ignition is turned off. You can
customize your automatic door locks to
work in four different ways, including a
setting that will unlock your vehicle when
the shift control lever is moved to the
PARK (P) position and the ignition key is
in the ON position.
See Section 2 of your Owner Manual.
