Caution
Lack of proper engine oil maintenance
can damage the engine. Driving with the
engine oil low can also damage the
engine. The repairs would not be covered
by the vehicle warranty. Check the oil
level as soon as possible. Add oil if
required, but if the oil level is within the
operating range and the oil pressure is
still low, have the vehicle serviced.
Always follow the maintenance schedule
for changing engine oil.
Engine Coolant Temperature
Gauge
This gauge measures the engine coolant
temperature.
The warning area at the far end of the
gauge may appear shaded or may be
colored red.
If the pointer approaches the warning area
the engine may be too hot. Pull off the road
and idle the engine to cool it down.
Under some driving conditions, including
those listed below, it is normal for the
temperature to rise above the usual
operating range and approach the far end of
the gauge:
Instruments and Controls
Stop and go driving in heavy traffic
High speed operation in warm weather
Uphill driving
Trailer towing or hauling a heavy load
It is normal for the reading to fluctuate.
If the gauge pointer reaches the warning
area at the far end of the gauge and
remains there for more than 30 seconds, the
engine coolant has overheated. Pull over and
stop the vehicle as soon as it is safe to do
so. Then, turn the engine off immediately.
