NOTE:
This feature can be programmed through the
Uconnect system. Refer to “Uconnect Settings”
in “Multimedia” for further information.
Headlight Delay
To aid in your exit, your vehicle is equipped with
a headlight delay that will leave the headlights
on for approximately 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.
NOTE:
This feature can be programmed through the
Uconnect system. Refer to “Uconnect Settings”
in “Multimedia” for further information.
Lights-On Reminder
If the headlights, parking lights, or cargo lights
are left on after the ignition is placed in the OFF
position, a chime will sound when the driver’s
door is opened.
Front Fog Lights — If Equipped
To activate the front fog lights, turn on the
parking lights or low beam headlights and push
in the center of the headlight switch control
knob. Pushing the headlight switch control knob
a second time will turn the front fog lights off.

Front Fog Light Switch

Turn Signals
Move the multifunction lever up or down and
the arrows on each side of the instrument
cluster display will flash to show proper opera -
tion of the front and rear turn signal lights.
NOTE:
If either light remains on and does not flash, or
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.
Lane Change Assist — If Equipped
Tap the multifunction lever up or down once,
without moving beyond the detent, and the turn
signal (right or left) will flash three times then
automatically turn off.
Cargo Lights/Trailer Spotter Lights — If
Equipped
The cargo lights (if equipped) and trailer spotter
lights (if equipped) are turned on by pushing the
cargo lights button located on the lower half of
the headlight switch.

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. 3. Instrument Cluster Display
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.

tion.
3. Speedometer
Indicates vehicle speed. 4. 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.
5. 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, see “Servicing And
Maintenance.” Follow the warnings under the
Cooling System Pressure Cap paragraph.
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.

2. Engine Coolant Temperature
This gauge shows the engine coolant temperature. 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
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

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 -
diate service should be obtained from an
authorized dealer.
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.

5. Speedometer
Indicates vehicle speed.
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 — Diesel
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 possibly 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.

The DEF tank on these vehicles is designed
with a large amount of full reserve. So the
level sensor will indicate a full reading even
before the tank is completely full. To put it
another way, there’s additional storage
capacity in the tank above the Full mark
that’s not represented in the gauge. You may
not see any movement in the reading – even
after driving up to 200 miles
(321 kilometers) in some cases.
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
