Diesel Exhaust Fluid (DEF) Warning Messages
Your vehicle will begin displaying warning messages when the DEF level reaches a
driving range of approximately 350 miles (563 km). If the following warning message
sequence is ignored, your vehicle may be limited to a maximum speed of 5 MPH
(8 km/H) unless DEF is added.
•DEF Low Refill Soon — This message will display when the low level is reached,
during vehicle start up, and with increased frequency during vehicle operation.
It will be accompanied by a single chime. Approximately 5 gallons (19 Liters) of
DEF is required to refill the tank when this message is initially displayed on pickup
applications, and approximately 7 gallons (28 Liters) are required on chassis-cab
applications.
• Speed Limited to 5 MPH in XXX mi Refill DEF — This message will continuously
display if the “DEF Low Refill Soon” message is ignored, and the frequency of
occurance of the chime will increase unless up to 2 gallons (7.5 Liters) of DEF is
added to the tank.
• 5 MPH Max Speed on Restart, Long Idle or Refuel Refill DEF — This message will
continuously display when the 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.
Add a minimum of 2 gallons (9.5 Liters) of DEF to the tank in order to avoid vehicle
operation at a maximum speed of 5 MPH (8 km/H).
• 5 MPH Max Speed Refill DEF — The vehicle will only be capable of a maximum
speed of 5 MPH (8 km/H) when this message is displayed. Add up to 2.5 gallons
(9.5 Liters) of DEF to the tank to restore normal vehicle operation.

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.

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.

- 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).

CAUTION!
• Mixing of engine coolant (antifreeze) other than specified Organic AdditiveTechnology (OAT) engine coolant (antifreeze), may result in engine damage and
may decrease corrosion protection. Organic Additive Technology (OAT) engine
coolant is different and should not be mixed with Hybrid Organic Additive
Technology (HOAT) engine coolant (antifreeze) or any “globally compatible”
coolant (antifreeze). If a non-OAT engine coolant (antifreeze) is introduced into
the cooling system in an emergency, the cooling system will need to be drained,
flushed, and refilled with fresh OAT coolant (conforming to MS-12106), by an
authorized dealer as soon as possible.
• Do not use water alone or alcohol-based engine coolant (antifreeze) products. Do not use additional rust inhibitors or antirust products, as they may not be
compatible with the radiator engine coolant and may plug the radiator.
• This vehicle has not been designed for use with propylene glycol-based engine coolant (antifreeze). Use of propylene glycol-based engine coolant (antifreeze)
is not recommended.
