2008 CADILLAC CTS warning light

Highbeam On Light
This light comes on when
the high-beam headlamps
are in use.
SeeHeadlamp High/Low-Beam Changer on page 3-8
for more information.
Fuel Gage
The fuel gage shows
approximately how much
fuel is in the fuel tank.
It works only when
the ignition is in the
ON/RUN position.If the fuel supply gets low, the Fuel Level Low message
will appear on the Driver Information Center (DIC)
and a single chime will sound. SeeDIC Warnings and
Messages on page 3-56for more information.
Here are a few concerns some owners have had about
the fuel gage. All of these situations are normal and
do not indicate that anything is wrong with the fuel gage:
At the gas station the gas pump shuts off before
the gage reads full.
The gage may change when you turn, stop quickly
or accelerate quickly.
It takes a little more or less fuel to ll the tank than
the gage indicated. For example, the gage may
have indicated that the tank was half full, but
it actually took a little more or less than half the
tank’s capacity to ll the tank.
