Transmission Temperature Gage (If Equipped)
When your ignition is on, the gage shows the
temperature of the transmission oil. A reading in the
warning zone means you must stop driving and check
into the cause. One possible cause is a low oil level in
the transmission.
NOTICE:
If you drive when the transmission temperature
gage is in the warning zone, you can badly
damage the transmission.
1-38
If you have an automatic
transmission and this
gage, it is located to the
right of the dash mounted
shift lever.
Low Coolant Warning Light
The warning light should come on briefly, as a check,
when you turn on the ignition.
When it comes on, you will also hear a warning tone at
five beats per second for 10 seconds. See "Engine
Coolant" in the Index and have your vehicle serviced as
soon as you can.
This light may also come on if your vehicle is equipped
with the optional automatic engine shutdown system and
engine shutdown has begun. See "Engine Automatic
Shutdown" in the Index.
You have a LOW
COOLANT warning
light. If this light comes
on, your system is low on
coolant and the engine
may overheat.
