GETTING TO KNOW YOUR VEHICLE17
NOTE:When replacing the battery, ensure the (+) sign on
the battery is facing upward. Avoid touching the
new battery with your fingers. Skin oils may cause
battery deterioration. If you touch a battery, clean
it with rubbing alcohol.
5. Replace the battery by using your thumb to
push down and slide the battery under the
small lip on the top edge of the opening.

Key Fob Battery Replacement

6. To assemble the key fob case, line up the top edge of the back cover with the top of the fob,
and press the edges into the interlocking
hinges until all edges snap together with no
large visual gaps. 7. Reinsert the emergency key until it locks into
place.
NOTE:The key fob battery should only be replaced by
qualified technicians. If the battery requires
replacement, see an authorized dealer.
Programming And Requesting Additional
Key Fobs
Programming the key fob may be performed by an
authorized dealer.
NOTE:
Once a key fob is programmed to a vehicle, it
cannot be repurposed and reprogrammed to
another vehicle.
Only key fobs that are programmed to the
vehicle electronics can be used to start and
operate the vehicle. Once a key fob is
programmed to a vehicle, it cannot be
programmed to any other vehicle.
Duplication of key fobs may be performed at an
authorized dealer. This procedure consists of
programming a blank key fob to the vehicle
electronics. A blank key fob is one that has never
been programmed.
WARNING!
The integrated key fob contains a coin cell
battery. Do not ingest the battery; there is a
chemical burn hazard. If the coin cell battery is
swallowed, it can cause severe internal burns
in just two hours and can lead to death.
If you think a battery may have been swal-
lowed or placed inside any part of the body,
seek immediate medical attention.
Keep new and used batteries away from chil -
dren. If the battery compartment does not
close securely, stop using the product and
keep it away from children.
WARNING!
Always remove the key fobs from the vehicle
and lock all doors when leaving the vehicle
unattended.
Always remember to place the Keyless
Enter ‘n Go™ Ignition in the OFF position.

ESCRIPTIONS

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 Ú page 81.
The display always shows one of the main
menu item after the ignition is placed on.
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. Immediate
service should be obtained from an autho -
rized dealer. 5. Speedometer
Indicates vehicle speed.
6. 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 oper -
ating range. 7. 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.WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. It is recommended to call an authorized
dealer for service if your vehicle overheats. If you
decide to look under the hood yourself, Follow
the warnings under the Cooling System Pressure
Cap paragraph Ú page 354.
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.

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
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
display messages Ú
page 81.
The display always shows one of the main
menu item after the ignition is placed 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. Speedometer
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
Warning Message or Malfunction Indicator
Light (MIL) will be displayed. More informa -
tion is available in the instrument cluster
display section under the heading of DEF
Warning Messages. 7. 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.
NOTE:
The gauge may take up to five seconds to
update after adding a gallon or more of 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.WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. It is recommended 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.
