Gauges
Tachometer
This gauge shows engine speed in revolutions-
per-minute (RPM) times 1,000. Avoid excessive
engine speeds in any part of the red warning
zone, particularly when driving downhill or in
lower gears.
Coolant Temperature Gauge
This gauge shows the engine coolant tempera-
ture. The gauge pointer will likely show higher
temperatures when driving in hot weather, up
mountain grades, or in heavy stop and go
traffic. If the red LED light turns on, stop the vehicle and
turn off the engine until the cause is corrected.
Oil Temperature Gauge
This gauge shows the oil temperature. The
gauge pointer will likely show higher tempera-
tures when driving in hot weather, up moun-
tain grades, or in heavy stop and go traffic. If
the red LED light turns on, stop the vehicle and turn off
the engine until the cause is corrected.
Oil Pressure Gauge
This gauge shows engine oil pressure when the
engine is running. The pressure will vary with
engine speed, oil viscosity, and engine tem-
perature. Oil pressures will be higher as the
engine is warming up. The normal operating pressure is
between 20 and 80 psi (pounds per square inch). If the
pointer remains in the red range, turn off the engine until
the cause is corrected.

²Trailer towing
²Off-road or desert driving
²If equipped for and operating with E±85 (ethanol) fuel
If none of these apply to you, then change your engine oil
every 6,000 miles (10 000 km) or 6 months, whichever
comes first and follow the maintenance recommenda-
tions in ScheduleA.
CAUTION!
Overfilling the crankcase will cause oil aeration and
loss of oil pressure. This could damage your engine.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, select only engine oils that
meet the American Petroleum Institute (API) certification
and SAE viscosity standards.
American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol on the front of an oil
container means that the oil has
been certified by the American
Petroleum Institute (API) to meet
all the lubrication requirements
specified by the manufacturer.

Engine Oil Viscosity Chart
The proper SAE viscosity grade of engine oil should be
selected based on the following recommendation and be
within the operating temperature shown in the engine oil
viscosity chart.
Synthetic Engine Oils
There are a growing number of engine oils being pro-
moted as either synthetic or semi-synthetic. If you choose
to use such a product, useonlythose oils that meet the
American Petroleum Institute (API) and SAE viscosity
standard. Follow the service schedule that describes your
driving type.
Materials Added To Engine Oils
It is not necessary to add any materials to crankcase oils
for most types of vehicle operation. The addition of
materials containing antirust or antiscuff additives can be
beneficial under certain conditions. These include: infre-
quent operation, short trips, and during break-in after a
major engine overhaul. The manufacturer's Engine Oil
Supplement is recommended for these situations.
Disposing of Used Engine Oil
Care should be taken in disposing of used engine oil from
your vehicle. Used oil, indiscriminately discarded, can
