102 GETTING TO KNOW YOUR INSTRUMENT PANEL
BASE / MIDLINE INSTRUMENT CLUSTER
D
ESCRIPTIONS — DIESEL
1. Tachometer
Indicates the engine speed in revolutions
per minute (RPM x 1000).
2. Engine Coolant Temperature
This gauge shows the engine coolant tempera-
ture. The gauge pointer will likely show higher
temp
eratures 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.
3. Instrument Cluster Display
When the appropriate conditions exist, this
display shows the instrument cluster
display messages
Ú page 104.
The display always shows one of the main
menu items after ignition on.
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. Immediate
service should be obtained from an autho
-
rized dealer.
5. S
peedometer
Indicates vehicle speed.
6. Diesel Exhaust Fluid (DEF) Gauge
The DEF Gauge displays the actual level of
Diesel Exhaust Fluid in the DEF tank. DEF is
required to maintain normal vehicle opera
-
tion and emissions compliance. If some-
thing is wrong with the gauge, a DEF
W
arn
ing Message or Malfunction Indicator
Light (MIL) will be displayed
Ú page 115.
NOTE:
The gauge may take up to five seconds to
update after adding a gallon or more of
Diesel Exhaust Fluid 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 12°F (-11°C). The DEF
line heater will possibly warm up the DEF
fluid and allow the gauge to update after a
period of run time. Under very cold condi
-
tions, it is possible that the gauge may not
r
efl
ect the new fill level for several drives.
Outside temperature can affect DEF
consumption. In cold conditions, 12°F
(-11°C) and below, the DEF gauge needle
can stay on a fixed position and may not
move for extended periods of time. This is a
normal function of the system.
7. Fuel Gauge
The gauge 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
door i
s located.
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
Ú
page 389.
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.
