Speedometer
The Speedometer indicates the vehicle
speed in miles per hour (mph) and in
kilometers per hour (km/h).
Engine Oil Pressure
CAUTION
Continuing to operate your vehicle with
insuf
ficient oil pressure will cause seri-
ous engine damage. Failure to comply
may
result in equipment or property
damage.
The Engine Oil Pressure gauge monitors
the oil pressure providing coolant to the
Engine. It is important to maintain oil
pressure within acceptable limits. If oil
pressure drops below the minimum PSI/
kPa, the Stop Engine warning light will
illuminate, a Popup will appear (see
Popups
on page 69), and an audible
alarm will sound.
If the oil pressure fails to rise within 10
seconds of starting the engine, stop the
engine and determine the cause. Check
the engine manufacturer's manual for the
correct oil pressure ranges for your
vehicle's engine. If the oil pressure
suddenly drops, or the audible alarm and
engine oil pressure telltale (see Low Oil
Pressure on page 30) come on while
driving, safely stop the engine and address
the issue. For further information on engine
gauges and operating your engine
properly, see Engine Maintenance on page
241.
Engine Coolant Temperature
The Engine Coolant (water) Temperature
gauge indicates the temperature of the
engine coolant.
If the coolant temperature exceeds the
maximum limits, a red warning lamp in the
gauge will turn on and an audible warning
will sound. If the coolant temperature
continues to rise, the Check Engine and/or
Stop Engine lights will also come on.
CAUTION
This should be considered an emer-
gency
. You should stop the vehicle as
safely as possible and turn OFF the ig-
nition. The vehicle must be serviced
and the problem corrected before driv-
ing again. Failure to do so may cause
severe transmission damage.
Under normal operating conditions, the
water temperature gauge should register
between 165° and 205° F (74° and 90° C).
Under certain conditions, somewhat higher
temperatures may be acceptable. The
maximum allowable temperature is 220° F
(104° C) with the cooling system
pressurized, except for certain engines.
Check the engine manual to be sure.
