Gages
Fuel Gage
Gasoline Engine Diesel Engine
The fuel gage, when the ignition is on, tells you about how much fuel YOLI
have left in your tank. The gage will first indicate empty before you are out

and you should get more fuel as soon as possible.
Listed are
four situations you may experience with your fuel ea tracre:
At the gas station, the fuel pump shuts off before the gage reads ~LIII.

ProCarManuals.com

It takes a little more or less fuel to fill up than the fuel gage indicated.
For example, the gage may have indicated the tank was half
full, but it
actually took a little more or less than half the tank’s capacity to fill the
tank.
The gage moves a little when you turn a corner or speed up.
0 The gage doesn’t go back to empty when you turn off the ignition.
None of these indicate a problem with the fuel gage.
For information on how to fill your fuel tank, see “Fuel
- Filling Your
Tank”
in the Index.
For your
fuel tank capacity, see “Fuel -Tank Capacity” in the Index.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature. Most of the time, the gage
pointer will show your coolant temperature at 210°F (99”C), or less. But,
if
you are pulling a heavy load or driving up hills, your coolant temperature
may rise and fall near
the red 260°F (1 28°C) mark. This is normal. If the
gage pointer moves
to the red 260°F (1 28°C) mark, your engine is too hot!
It means that your engine coolant has overheated. You should pull off the
road, stop
your vehicle, and turn off the engine as soon as possible.
Hot Coolant Can Burn You Badly!
In “Problems on the Road,” this manual shows what to do. See “Engine
Overheating”
in the Index.

Oil Pressure Gage
The oil pressure gage shows the engine oil pressure in psi (pounds per
square inch) when the engine is running. Canadian vehicles indicate
pressure
in kPa (kilopascals). Oil pressure may vary with engine speed,
outside temperature and
oil viscosity, but readings above the low pressure
zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a dangerously low oil
level or other problem causing
low oil pressure. Check your oil as soon as
possible.
A CAUTION:
Don’t keep driving if the oil pressure is low. If you do, your
engine can become
so hot that it catches fire. You or others could
be burned. Check your oil as soon
as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil problems can be
costly and is not covered
by your warranty.

Voltmeter
When your engine is not running, but the ignition is in the RUN position,
this gage shows your battery’s state of charge
in DC volts.
When
the engine is running, the gage shows the condition of the charging
system. Readings between the low and high warning zones indicate
the
normal operating range.
Readings in the low warning zone may occur when a large number
of
electrical accessories are operating in the vehicle and the engine is left at an
idle
for an extended period. This condition is normal since the charging
system
is not able to provide full power at engine idle. As engine speeds are
increased,
this condition should correct itself as higher engine speeds allow
the charging system
to create maximum power.
You can only drive for a short time with the reading in either warning zone.
If you must drive, turn off all unnecessary accessories.
Readings in either warning zone indicate a possible problem
in the electrical
system. Have the vehicle serviced as soon as possible.
