Instrument cluster
Transmission fluid temperature gauge
If the gauge is in the:
White area (normal) - the
transmission fluid is within the
normal operating temperature
(between "H" and "C").
Yellow area (warning) — the
transmission fluid is higher than
normal operating temperature. This
can be caused by special operation
conditions (i.e. towing or off road
use). Refer to Special Operating
Conditions in the scheduled
maintenance guide for instructions.
Operating the transmission for
extended periods of time with the
gauge in the yellow area may cause
internal transmission damage.
Altering the severity of the driving conditions is recommended to lower
the transmission temperature into the normal range.
Red area (over temperature) —
the transmission fluid is overheating.
Stop the vehicle to allow the
temperature to return to normal
range.
