Engine Coolant Temperature; Warning Light (Cts); Engine Coolant Temperature Gage - Cadillac 2006 CTS Owner's Manual

If the TC warning light stays on or comes on while you
are driving, pull off the road as soon as possible
and stop carefully. Try resetting the system by turning
the ignition off then back on. If the light still stays
on or comes back on again while you are driving, your
vehicle needs service. Have the Traction Control
System (TCS) inspected as soon as possible. See
Traction Control System (TCS) (CTS) on page 4-9 or
Traction Control System (TCS) (CTS-V) on page 4-10
for more information.

Engine Coolant Temperature

Warning Light (CTS)

It will go out after a few seconds. If the light does not
come on, see your dealer.
3-40
This light will come on
when you first start the
vehicle as a check
to let you know that the
light is working.
If the light does not go out or if the light comes on and
stays on while you are driving, your vehicle may
have a problem with the cooling system. You should
stop the vehicle and turn off the engine as soon
as possible to avoid damage to the engine. A warning
chime will also sound when this light is on.
See Engine Overheating on page 5-28 for more
information.

Engine Coolant Temperature Gage

That reading means the same thing as the warning
light – the engine coolant is very hot. See Engine
Overheating on page 5-28.
This gage shows the
engine coolant
temperature. If the gage
pointer moves into
the shaded area, the
engine is too hot.
