Diesel Exhaust Fluid (DEF) Fault Warning
Messages
There are five 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
200 miles (322 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 continu -
ously 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 shut off and restarted.
 If the vehicle is idled for an extended period of
time, approximately one hour or greater.
 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 an 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.

Incorrect DEF Detected See Dealer — This message will
display when the fault is initially detected, each time
the vehicle is started, and periodically during driving.

QUIPPED
This vehicle is equipped with an Intelligent Battery Sensor
(IBS) to perform additional monitoring of the electrical
system and status of the vehicle battery.
In cases when the IBS detects charging system failure, or
the vehicle battery conditions are deteriorating, electrical
load reduction actions will take place to extend the driving
time and distance of the vehicle. This is done by reducing
power to or turning off non-essential electrical loads.
Load reduction is only active when the engine is running.
It will display a message if there is a risk of battery
depletion to the point where the vehicle may stall due to
lack of electrical supply, or will not restart after the current
drive cycle.
When load reduction is activated, the message “Battery
Saver On Some Systems May Have Reduced Power” will
appear in the instrument cluster.
These messages indicate the vehicle battery has a low
state of charge and continues to lose electrical charge at
a rate that the charging system cannot sustain.
NOTE:

The charging system is independent from load reduc -
tion. The charging system performs a diagnostic on the
charging system continuously.

If the Battery Charge Warning Light is on it may indicate
a problem with the charging system
