StabiliTrak ® Indicator Light
If equipped, this
warning light should
come on briefly when
the engine is started.
If the warning light does not come on then, have it fixed
so it will be ready to warn you if there is a problem.
If it stays on, or comes on when you are driving,
there may be a problem with your StabiliTrak
® system
and your vehicle may need service. When this warning
light is on, the system is off and will not limit wheel
spin. Adjust your driving accordingly.
This light will also flash when the StabiliTrak ® system
is active.
If the StabiliTrak ® system warning light comes on
and stays on for an extended period of time when
the system is turned on, your vehicle needs service.
See StabiliTrak
® System on page 4-7 for more
information.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
It also provides an indicator of how hard your vehicle
is working. During a majority of the operation, the gage
will read 210°F (100°C) or less. If you are pulling a
load or going up hills, it is normal for the temperature
to fluctuate and approach the 250°F (122°C) mark.
If the gage reaches the 260°F (125°C) mark, it indicates
that the cooling system is working beyond its capacity.
See Engine Overheating on page 5-27.
