For the CTS-V, the tracer lights also flash when
it is time to up-shift to avoid the engine speed limit.
See Automatic Transmission Operation on page 2-37
or Manual Transmission Operation on page 2-42 for
more information.
Engine Speed Limiter
This feature prevents the engine speed from reaching
an unsafe level. If the level is too high, the throttle closes
or limits the fuel supply until the engine speed returns
to a safe level. Throttle operation and fuel supply returns
to normal when engine speed is lowered.
For the CTS-V, the tachometer tracer lights flashes prior
to reaching engine speed limit. The tracer lights also
flash on automatic transmission vehicles while in
the DSC or Tap Shift modes.
Safety Belt Reminders
Safety Belt Reminder Light
When the engine is started, a chime sounds for
several seconds to remind a driver to fasten the safety
belt, unless the driver safety belt is already buckled.
The safety belt light
comes on and stays on
for several seconds, then
flashes for several more.
This chime and light are repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver
safety belt is already buckled, neither the chime nor
the light comes on.
Passenger Safety Belt Reminder Light
Several seconds after the engine is started, a
chime sounds for several seconds to remind the front
passenger to buckle their safety belt. This only occurs
if the passenger airbag is enabled. See Passenger
Sensing System on page 1-63 for more information.
The passenger safety belt light, located on the instrument
panel, comes on and stays on for several seconds and
then flashes for several more.
