Traction Off Light
If you have the Traction
Assist System, this light
should come on briefly
when you turn the ignition
to RUN.
If the light does not come on then, the system may
require service; have it fixed so it will be there to warn
you if the system is turned off.
If the light stays on, or comes on when you are driving,
there may be a problem with your Traction Assist System
and your vehicle may need service. When this light is on,
the system will not limit wheel spin. Adjust your driving
accordingly.
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.
