Engine Coolant Temperature Gage
This gage shows the
engine coolant temperature.
If the gage pointer moves
into the red warning zone,
your engine is hot.
To prevent engine overheating, the air conditioning
compressor will turn off automatically, a fast
- pulsed
chime will sound, and the message ENGINE HOT...A/C
OFF will appear in the Driver Information Center (DIC).
As the engine cools down, the air conditioning
compressor will automatically turn back on.
If the coolant temperature is over 262
_F (128_C),
the message HOT...IDLE ENGINE will appear. It means
you should reduce the engine load and speed to prevent
the engine from overheating.
If the coolant temperature is over 268
_F (131_C),
the message HOT...STOP ENGINE will appear.
It means that your engine coolant has overheated.
You should pull off the road, stop your vehicle and
turn off the engine as soon as possible.
Your vehicle is equipped with an Overheated Engine
Protection Operating Mode. See “Engine Overheating”
in the Index for more information.
If your coolant level is low, the message LOW ENGINE
COOLANT will appear on the Driver Information
Center. Check your coolant level as soon as possible.
