Instruments and Controls 4-27
If this happens, start the engine
again to reset the system. If the
ABS light stays on, or comes on
again while driving, the vehicle
needs service. If the regular brake
system warning light is not on, the
vehicle still has brakes, but not
antilock brakes. If the regular brake
system warning light is also on,
the vehicle does not have antilock
brakes and there is a problem with
the regular brakes. See Brake
System Warning Light on
page 4‑25.
For vehicles with a Driver
Information Center (DIC), see
Driver Information Center (DIC) on
page 4‑31 for all brake related DIC
messages.
Up-Shift Light
The vehicle may have an up-shift
light. It indicates when to shift to
the next higher gear for best fuel
economy.
See Manual Transmission on
page 8‑32 for more information.
For the CTS-V, the tracer lights
function as a performance
up-shift light.
The tracers flash to indicate when
to shift to the next higher gear to
avoid the engine speed limit.
See Automatic Transmission on
page 8‑28 or Manual Transmission
on page 8‑32 for more information.

OFF Light
This light comes on briefly while
starting the engine. If it does not,
have the vehicle serviced by your
dealer.
This light comes on when the
StabiliTrak system is turned off.
If StabiliTrak is off, the Traction
Control System (TCS) is also off.
If the TCS is off, the system does
not assist in controlling the vehicle.
Turn on the TCS and the StabiliTrak
systems and the warning light
turns off.
