Diesel Exhaust Fluid (DEF) Fault Warning Messages
There are four different messages which are displayed if the vehicle detects that the
DEF system has been filled with a fluid other than DEF, has experienced component
failures, or when tampering has been detected. The vehicle may be limited to a
maximum speed of 5 MPH (8 km/H) if the DEF system is not serviced within less than
250 miles (402 km) of the fault being detected.
When the DEF system needs to be serviced the following warnings will display:
•Service DEF System – See Dealer — This message will display when the fault is
initially detected, each time the vehicle is started, and periodically during driving.
The message will be accompanied by a single chime. We recommend you drive to
your nearest authorized dealer and have your vehicle serviced as soon as possible.
• 5 MPH Max Speed in 150 mi Service DEF System See Dealer — This message will
display if the DEF system has not been serviced after the “Service DEF System –
See Dealer” message is displayed. This message will continuously display until the
mileage counter reaches zero, and will be accompanied by a periodic chime. The
message will continue to countdown until it reaches zero unless the vehicle is
serviced. We recommend you drive to your nearest authorized dealer and have your
vehicle serviced immediately.
NOTE:
Under some circumstances this mileage counter may start with a value of less than
150 miles (241 km). For example, if recurring faults are detected in a time interval
of less than 40 hours, the counter may restart at the value where it stopped when a
previous fault was temporarily remedied, or at a minimum of 50 miles (80 km).
• 5 MPH Max Speed on Restart, Long Idle or Refuel Service DEF See Dealer — This
message will continuously display when the mileage counter reaches zero, and will
be accompanied by a periodic chime.
The vehicle will only be capable of a maximum speed of 5 MPH upon the first of the
following conditions to occur: • If the vehicle is shutoff and restarted.
• If the vehicle is idled for an extended period of time, approximately one hour orgreater.
• If the system detects that the level of fuel in the tank has increased.
• 5 MPH Max Speed Service DEF System See Dealer — This message will continuously
display, and will be accompanied by a periodic chime. Although the vehicle can be
started and placed in gear, the vehicle will only operate at a maximum speed of
5 MPH. Your vehicle will require towing, see your authorized dealer for service.
NOTE:
When this message is displayed, the engine can still be started. However, the vehicle
will only operate at a maximum speed of 5 MPH.

INSTRUMENT CLUSTER WARNING LIGHTS
- Electronic Stability Control (ESC) Activation/Malfunction Indicator
Light
If this indicator light flashes during acceleration, apply as little throttle as possible.
While driving, ease up on the accelerator. Adapt your speed and driving to the
prevailing road conditions. To improve the vehicle's traction when starting off in deep
snow, sand or gravel, it may be desirable to switch the ESC system off.
- Tire Pressure Monitoring System (TPMS) Light
Each tire, including the spare (if provided), should be checked monthly, when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard or tire inflation pressure
label, you should determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a Tire Pressure
Monitoring System (TPMS) which display in the Electronic Vehicle Information
Center (EVIC) when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure EVIC display illuminates, you should stop and
check your tires as soon as possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
IF THE LIGHT STARTS FLASHING INDICATING A LOW TIRE PRESSURE, ADJUST THE AIR
PRESSURE IN THE LOW TIRE TO THE AIR PRESSURE SHOWN ON THE VEHICLE PLACARD OR
TIRE INFLATION PRESSURE LABEL LOCATED ON THE DRIVER'S DOOR.
NOTE:
After inflation, the vehicle may need to be driven for 20 minutes before the flashing light
will turn off.
WHAT TO DO IN EMERGENCIES
169
Please note that the TPMS is not a substitute for proper tire maintenance, and it is
the driver’s responsibility to maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS low EVIC display.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate
when the system is not operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the system detects a malfunction,
the telltale will flash for approximately one minute and then remain continuously
illuminated. This sequence will continue each time the vehicle is restarted as long as
the malfunction exists.
When the malfunction indicator is illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or wheels on your vehicle, to
ensure that the replacement or alternate tires and wheels allow the TPMS to continue
to function properly.
NOTE:
Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C) of air
temperature change. Keep this in mind when checking tire pressure inside a garage,
especially in the Winter. Example: If garage temperature is 68°F (20°C) and the
outside temperature is 32°F (0°C), then the cold tire inflation pressure should be
increased by 3 psi (21 kPa), which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.
CAUTION!
The TPMS has been optimized for the original equipment tires and wheels. TPMS
pressures and warning have been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor damage may result when using
replacement equipment that is not of the same size, type, and/or style. Aftermarket
wheels can cause sensor damage. Do not use tire sealant from a can, or balance
beads if your vehicle is equipped with a TPMS, as damage to the sensors may result.
- Engine Temperature Warning Light
This light warns of an overheated engine condition.
If the light turns on and a warning chime sounds while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also, shift the transmission into
NEUTRAL and idle the vehicle. If the temperature reading does not return to normal,
turn the engine off immediately.
We recommend that you do not operate the vehicle or engine damage will occur. Have
the vehicle serviced immediately.

- Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of an onboard diagnostic system called
OBD II that monitors engine and automatic transmission control systems. The light
will illuminate when the key is in the ON/RUN position before engine start. If the bulb
does not come on when turning the key from OFF to ON/RUN, have the condition
checked promptly.
Certain conditions, poor fuel quality, etc., may illuminate the light after engine start.
The vehicle should be serviced if the light stays on through several of your typical driving
cycles. In most situations, the vehicle will drive normally and will not require towing.
CAUTION!
Prolonged driving with the Malfunction Indicator Light (MIL) on could cause damage
to the engine control system. It also could affect fuel economy and driveability. If the
MIL is flashing, severe catalytic converter damage and power loss will soon occur.
Immediate service is required.
WARNING!
A malfunctioning catalytic converter, as referenced above, can reach higher tempera-
tures than in normal operating conditions. This can cause a fire if you drive slowly or
park over flammable substances such as dry plants, wood, cardboard, etc. This could
result in death or serious injury to the driver, occupants or others.
- Electronic Stability Control (ESC) OFF Indicator Light
The ESC OFF indicator will illuminate when the Electronic Stability Control (ESC) is
turned off.
- Charging System Light
This light shows the status of the electrical charging system. If the charging system light
remains on, it means that the vehicle is experiencing a problem with the charging
system.
We recommend you do not continue driving if the charging system light is on. Have
the vehicle serviced immediately.
- Oil Pressure Warning Light
This light indicates low engine oil pressure. If the light turns on while driving, stop
the vehicle and shut off the engine as soon as possible. A chime will sound for four
minutes when this light turns on.
We recommend you do not operate the vehicle or engine damage will occur. Have the
vehicle serviced immediately.

- Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System (ABS). The light will turn on when the
ignition switch is turned to the ON/RUN position and may stay on for as long as four
seconds.
If the ABS light remains on or turns on while driving, it indicates that the Anti-Lock
portion of the brake system is not functioning and that service is required. However, the
conventional brake system will continue to operate normally if the BRAKE warning light
is not on.
If the ABS light is on, the brake system should be serviced as soon as possible to
restore the benefits of Anti-Lock brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have the light inspected by an
authorized dealer.
- Electronic Throttle Control (ETC) Light
This light informs you of a problem with the Electronic Throttle Control (ETC) system.
If a problem is detected, the light will come on while the engine is running. Cycle the
ignition when the vehicle has completely stopped and the shift lever is placed in the
PARK position; the light should turn off.
If the light remains lit with the engine running, your vehicle will usually be drivable;
however, see an authorized service center immediately. If the light is flashing when the
engine is running, immediate service is required and you may experience reduced
performance, an elevated/rough idle or engine stall and your vehicle may require towing.
- Air Bag Warning Light
This light will turn on for four to eight seconds as a bulb check when the ignition
switch is first turned to the ON/RUN position. If the light is either not on during
starting, stays on, or turns on while driving, have the system inspected at an
authorized dealer as soon as possible. Refer to “Occupant Restraints” in “Things To
Know Before Starting Your Vehicle” of your Owner’s Manual for further information.
NOTE:
The Air Bag System is designed to be maintenance free.
- SERV (Service) 4WD Indicator Light
The SERV 4WD light monitors the electric shift four-wheel drive system. If the SERV
4WD light stays on or comes on during driving, it means that the four-wheel drive
system is not functioning properly and that service is required.
For vehicles equipped with a premium cluster this indicator will display in the
Electronic Vehicle Information Center (EVIC).

- Transmission Temperature Warning Light
This light indicates that there is excessive transmission fluid temperature that might
occur with severe usage such as trailer towing. If this light turns on, stop the vehicle
and run the engine at idle, with the transmission in NEUTRAL, until the light turns
off. Once the light turns off, you may continue to drive normally.
CAUTION!
Continuous driving with the Transmission Temperature Warning Light illuminated
will eventually cause severe transmission damage or transmission failure.
WARNING!
If you continue operating the vehicle when the Transmission Temperature Warning
Light is illuminated you could cause the fluid to boil over, come in contact with hot
engine or exhaust components and cause a fire.
OIL CHANGE EVIC INDICATOR
Message
If an “oil change” message (shown as “Change Oil Soon” and “Oil Change Needed”)
appears and a single chime sounds, it is time for your next required oil change.
Resetting The Light After Servicing
1. Turn the ignition switch to the ON/RUN position (do not start engine).
2. Fully depress the accelerator pedal three times within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.
- Low Coolant Level Indicator Light
This light indicates low coolant level. If the light turns on while driving, stop the
vehicle and shut off the engine as soon as possible.

IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the potential for overheating by
taking the appropriate action:
• On the highways — slow down.
• In city traffic — while stopped, shift the transmission to NEUTRAL, but do notincrease engine idle speed.
NOTE:
There are steps that you can take to slow down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine cooling system and turning the A/C off can help remove this heat.
•
You can also turn the temperature control to maximum heat, the mode control to floor
and the blower control to high. This allows the heater core to act as a supplement to
the radiator and aids in removing heat from the engine cooling system.
CAUTION!
Driving with a hot cooling system could damage your vehicle. If the temperature
gauge reads HOT (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 HOT (H), and you hear continuous chimes, turn the engine off
immediately, and call for service.
WARNING!
You or others can be badly burned by hot engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming from under the hood, do not open
the hood until the radiator has had time to cool. Never try to open a cooling system
pressure cap when the radiator or coolant bottle is hot.

•For 4x2 and 4x4 trucks, when changing a rear wheel, assemble the jack drive tube
to the jack and connect the drive tube to the extension tube. Place the jack under
the axle between the spring and the shock absorber with the drive tubes extending
to the rear.
• Connect the jack tube extension and wheel wrench.
NOTE:
If the bottle jack will not lower by turning the dial (thumbwheel) by hand, it may be
necessary to use the jack drive tube in order to lower the jack.
• By rotating the wheel wrench clockwise, raise the vehicle until the wheel just clears the surface.
• Remove the wheel nuts and pull the wheel off. On single rear-wheel (SRW) trucks, install the spare wheel and wheel nuts with the cone shaped end of the wheel nuts
toward the wheel. On 3500 dual rear-wheel models (DRW) the wheel nuts are a
two-piece assembly with a flat face. Lightly tighten the wheel nuts. To avoid the
risk of forcing the vehicle off the jack, do not fully tighten the wheel nuts until the
vehicle has been lowered.
• Using the lug wrench, finish tightening the wheel nuts using a crisscross pattern. The correct wheel nut tightness is 130 ft lbs (176 N·m) torque (1500 Series),
135 ft lbs (183 N·m) torque for 2500/3500 single-rear wheel (SRW) models, and
140 ft lbs (190 N·m) for 3500 dual rear-wheel models. If in doubt about the
correct tightness, have them checked with a torque wrench by your authorized
dealer or at a service station.
• Install the wheel center cap and remove the wheel blocks. Do not install chrome or aluminum wheel center caps on the spare wheel. This may result in cap damage.
• Lower the jack to its fully closed position. If the bottle jack will not lower by turning the dial (thumbwheel) by hand, it may be necessary to use the jack drive
tube in order to lower the jack. Stow the replaced tire, jack, and tools as previously
described.
• Adjust the tire pressure when possible.
NOTE:
Do not oil wheel studs. For chrome wheels, do not substitute with chrome plated
wheel nuts.
