If the light still stays on or comes back on again while
you are driving, your vehicle needs service. Have
the traction control system inspected as soon as
possible. See
Traction Control System (TCS) (CTS) on
page 4-8 or Traction Control System (TCS) (CTS-V)
on page 4-10 for more information.
Engine Coolant Temperature
Warning Light (CTS)
This light tells you that
your engine is very hot.
This light will come on when you first start the vehicle
as a check to let you know that the light is working.
It will go out after a few seconds. If the light does not
come on, the bulb may be burned out. See your dealer
for assistance in changing the bulb.
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 sound when this light is on, also.
See Engine Overheating on page 5-29 and Message
Center (CTS-V) on page 3-52 for more information.
Engine Coolant Temperature Gage
This gage shows
the engine coolant
temperature. If the
gage pointer moves
into the shaded area,
the engine is too hot.
That reading means the same thing as the warning
light — the engine coolant is very hot. See
Engine
Overheating on page 5-29.
