Cadillac 2006 XLR, Owner'S Manual

Page: 80 / 448

Not all manual downshift requests will be accepted by
the transmission. To prevent excessive engine rpms,
each gear has a maximum vehicle speed associated
with it. Any downshift request above this speed will not
be allowed by the transmission.
If shifting is prevented for any reason, the current gear
will flash multiple times in the DIC, indicating that
the transmission has not shifted gears.
Some automatic downshifts may occur to maintain
minimum engine speed. This only happens the vehicle
is left in too high of a gear for the vehicle’s speed.
For example, if you have been driving in fifth gear range
and come to a stop without manually downshifting,
fifth gear will continue to display in the HUD. The
transmission will automatically downshift to second
gear. As you begin to drive and accelerate, the
transmission will automatically upshift as quickly as
possible to the selected fifth gear.
In higher gears, an automatic downshift will occur if you
press the accelerator pedal to the floor. This feature
provides adequate acceleration capabilities if you forget
to downshift manually.
Automatic upshifts and downshifts will not display in
the HUD.
DSC can be used while using cruise control, but
transmission shifting will be different while the cruise
control is on. This is not a malfunction and is necessary
to allow proper operation of the cruise control.
To return to fully automatic operation, move the shift
lever to the right and back into the AUTOMATIC
OVERDRIVE (D).
When accelerating your vehicle from a stop in snowy
and icy conditions, you may want to shift into second
gear. A higher gear allows you to gain more traction on
slippery surfaces.
