HEADLIGHT DELAY
To aid in your exit, your vehicle is equipped with
a headlight delay that will leave the headlights
on for up to 90 seconds. This delay is initiated
when the ignition is turned off while the headlight switch is on, and then the headlight
switch is cycled off. Headlight delay can be
canceled by either turning the headlight switch
on then off, or by placing the ignition in the ON/
RUN position.

there is a very fast flash rate, check for a defec
-
tive outside light bulb. If an indicator fails to
light when the lever is moved, it would suggest
that the indicator bulb is defective.

1. Tachometer

Indicates the engine speed in revolutions
per minute (RPM x 1000). 2. Voltmeter
When the vehicle is in the RUN state, the
gauge indicates the electrical system
voltage. The pointer should stay within
the normal range if the battery is
charged. If the pointer moves to either
extreme left or right and remains there
during normal driving, the electrical
system should be serviced.

When the appropriate conditions exist,
this display shows the instrument cluster
display messages. Refer to “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further informa-
tion.
4. Oil Pressure Gauge
The pointer should always indicate the oil
pressure when the engine is running. A
continuous high or low reading under
normal driving conditions may indicate a
lubrication system malfunction. Imme -
diate service should be obtained from an
authorized dealer.
5. Speedometer
Indicates vehicle speed.
6. Fuel Gauge
The pointer shows the level of fuel in the
fuel tank when the ignition is in the ON/
RUN position.
 The fuel pump symbol points
to the side of the vehicle where
the fuel door is located.
Refer to “Refueling The Vehicle — Gas
Engine” in “Starting And Operating” for
further information.
7. Temperature Gauge
The gauge pointer shows engine coolant
temperature. The pointer positioned
within the normal range indicates that
the engine cooling system is operating
satisfactorily.
The gauge pointer will likely indicate a
higher temperature when driving in hot
weather, up mountain grades, or when
towing a trailer. It should not be allowed
to exceed the upper limits of the normal
operating range.
WARNING!
A hot engine cooling system is dangerous.
You or others could be badly burned by steam
or boiling coolant. You may want to call an
authorized dealer for service if your vehicle
overheats. If you decide to look under the
hood yourself, refer to the warnings under
“Cooling System Pressure Cap” in see
“Servicing And Maintenance” for further
information.
CAUTION!
Driving with a hot engine cooling system
could damage your vehicle. If the
temperature gauge reads “H,” pull over and
stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops
back into the normal range. If the pointer
remains on the “H,” turn the engine off
immediately and call an authorized dealer for
service.

show higher temperatures when driving
in hot weather, up mountain grades, or in
heavy stop and go traffic. If the red Warning Light turns on while driving,
safely bring the vehicle to a stop, and
turn off the engine. DO NOT operate the
vehicle until the cause is corrected.

tion. 4. Oil Pressure Gauge
The pointer should always indicate some
oil pressure when the engine is running.
A continuous high or low reading under
normal driving conditions may indicate a
lubrication system malfunction. Imme
-

6. Fuel Gauge
The pointer shows the level of fuel in the
fuel tank when the ignition switch is in
the ON/RUN position.
 The fuel pump symbol points
to the side of the vehicle where
the fuel filler door is located.
Refer to “Refueling The Vehicle — Gas
Engine” in “Starting And Operating” for
further information.
7. Diesel Exhaust Fluid (DEF) Gauge
The DEF Gauge displays the actual level
of Diesel Exhaust Fluid in the DEF tank.
Diesel Exhaust Fluid (DEF) is required to maintain normal vehicle operation and
emissions compliance. If something is
wrong with the gauge, a DEF Warning
Message or Malfunction Indicator Light
(MIL) will be displayed. More information
is available in the instrument cluster
display section under the heading of
Diesel Exhaust Fluid (DEF) Warning
Messages.
NOTE:
The gauge may take up to five seconds to
update after adding a gallon or more of
Diesel Exhaust Fluid (DEF) to the DEF tank. If
you have a fault related to the DEF system,
the gauge may not update to the new level.
See an authorized dealer for service.
The DEF gauge may also not immediately
update after a refill if the temperature of the
DEF fluid is below 39°F (4°C). The DEF tank
heater will warm up the DEF fluid and allow
the gauge to update after a period of run
time. Under very cold conditions, it is possible
that the gauge may not reflect the new fill
level for several drives.
WARNING!
A hot engine cooling system is dangerous.
You or others could be badly burned by steam
or boiling coolant. You may want to call an
authorized dealer for service if your vehicle
overheats.
CAUTION!
Driving with a hot engine cooling system
could damage your vehicle. If the
temperature gauge reads greater “H,” pull
over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the
pointer drops back into the normal range. If
the pointer remains on the “h,” turn the
engine off immediately and call an authorized
dealer for service.
