Your vehicle has the ability to alert you to 
additional maintenance required on your vehicle or 
engine. Refer to the following messages that may 
be displayed on your instrument cluster display:
Exhaust Filter Nearing Full Safely Drive at 
Consistent Speeds to Clear  — This message will 
be displayed if the exhaust particulate filter 
reaches 80% of its maximum storage capacity. 
Under conditions of exclusive short duration 
and low speed driving cycles, your diesel engine 
and exhaust after-treatment system may never 
reach the conditions required to cleanse the 
filter to remove the trapped PM. If this occurs, 
the “Exhaust Filter XX% Full Safely Drive at 
Highway Speeds to Remedy” message will be 
displayed. If this message is displayed, you will 
hear one chime to assist in alerting you of this 
condition. By simply driving your vehicle at 
highway speeds for up to 20 minutes, you can 
remedy the condition in the particulate filter 
system and allow your diesel engine and 
exhaust after-treatment system to cleanse the 
filter to remove the trapped PM and restore the 
system to normal operating condition.
Exhaust System Regeneration in Process 
Continue Driving  — This message indicates that 
the DPF is self-cleaning. Maintain your current 
driving condition until regeneration is 
completed.
Exhaust System — Regeneration Completed  — 
This message indicates that the DPF 
self-cleaning is completed. If this message is 
displayed, you will hear one chime to assist in 
alerting you of this condition.
Exhaust System Service Required — 
See Dealer  — This message indicates regenera -
tion has been disabled due to a system malfunc -
tion. At this point the engine Powertrain Control 
Module (PCM) will register a fault code, the 
instrument panel will display a Malfunction Indi -
cator Light (MIL) light.
Exhaust Filter Full — Power Reduced 
See Dealer  — This message indicates the PCM 
has derated the engine to limit the likelihood of 
permanent damage to the after-treatment 
system. If this condition is not corrected and a 
dealer service is not performed, extensive 
exhaust after-treatment damage can occur. To 
correct this condition it will be necessary to have 
your vehicle serviced by an authorized dealer.
NOTE:Failing to follow the oil change indicator, changing 
your oil and resetting the oil change indicator by 
0 miles (0 kilometers) remaining will prevent the 
diesel exhaust filter from performing its cleaning 
routine. This will shortly result in a Malfunction 
Indicator Light (MIL) and reduced engine power. 
Only an authorized dealer will be able to correct 
this condition.
CAUTION!
See an authorized dealer, as damage to the 
exhaust system could occur soon with continued 
operation.CAUTION!

different based upon equipment options and 
current vehicle status. Some telltales are optional 
and may not appear.
RED WARNING LIGHTS
Air Bag Warning Light
This warning light will illuminate to 
indicate a fault with the air bag, and will 
turn on for four to eight seconds as a bulb 
check when the ignition is placed in the 
ON/RUN or ACC/ON/RUN position. This light will 
illuminate with a single chime when a fault with the 
air bag has been detected, it will stay on until the 
fault is cleared. If the light is not on during startup, 
stay on, or turns on while driving, have the system 
inspected at an authorized dealer as soon as 
possible.
Brake Warning Light
This warning light monitors various brake 
functions, including brake fluid level and 
parking brake application. If the brake 
light turns on it may indicate that the 
parking brake is applied, that the brake fluid level 
is low, or that there is a problem with the Anti-Lock 
Brake System reservoir.
If the light remains on when the parking brake has 
been disengaged, and the fluid level is at the full 
mark on the master cylinder reservoir, it indicates 
a possible brake hydraulic system malfunction or 
that a problem with the Brake Booster has been 
detected by the Anti-Lock Brake System (ABS) / 
Electronic Stability Control (ESC) system. In this 
case, the light will remain on until the condition has 
been corrected. If the problem is related to the 
brake booster, the ABS pump will run when 
applying the brake, and a brake pedal pulsation 
may be felt during each stop.
The dual brake system provides a reserve braking 
capacity in the event of a failure to a portion of the 
hydraulic system. A leak in either half of the dual 
brake system is indicated by the Brake Warning 
Light, which will turn on when the brake fluid level 
in the master cylinder has dropped below a 
specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp 
cornering maneuvers, which change fluid level 
conditions. The vehicle should have service 
performed, and the brake fluid level checked.
If brake failure is indicated, immediate repair is 
necessary.
Vehicles equipped with the Anti-Lock Brake System 
(ABS) are also equipped with Electronic Brake 
Force Distribution (EBD). In the event of an EBD 
failure, the Brake Warning Light will turn on along 
with the ABS Light. Immediate repair to the ABS 
system is required.
Operation of the Brake Warning Light can be 
checked by turning the ignition switch from the OFF

Engine Check/Malfunction Indicator 
Warning Light (MIL)
The Engine Check/Malfunction Indicator 
Light (MIL) is a part of an Onboard 
Diagnostic System called OBD II that 
monitors engine and automatic 
transmission control systems. This warning light 
will illuminate when the ignition is in the ON/RUN 
position before engine start. If the bulb does not 
come on when turning the ignition switch from OFF 
to ON/RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas 
cap, poor quality fuel, etc., may illuminate the light 
after engine start. The vehicle should be serviced if 
the light stays on through several typical driving 
styles. In most situations, the vehicle will drive 
normally and will not require towing.
When the engine is running, the MIL may flash to 
alert serious conditions that could lead to 
immediate loss of power or severe catalytic 
converter damage. The vehicle should be serviced 
by an authorized dealer as soon as possible if this 
occurs.
Service 4WD Warning Light — If Equipped
This warning light will illuminate to signal 
a fault with the 4WD system. If the light 
stays on or comes on during driving, it 
means that the 4WD system is not 
functioning properly and that service is required. It 
is recommend you drive to the nearest service 
center and have the vehicle serviced immediately.
WARNING!
A malfunctioning catalytic converter, as 
previously referenced, can reach higher 
temperatures 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.
CAUTION!
Prolonged driving with the Malfunction Indicator 
Light (MIL) on could cause damage to the 
vehicle 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.

Service Forward Collision Warning (FCW) 
Light — If Equipped
This warning light will illuminate to 
indicate a fault in the Forward Collision 
Warning System. Contact an authorized 
dealer for service  Úpage 291.
Service Stop/Start System Warning Light — 
If Equipped
This warning light will illuminate when the 
Stop/Start system is not functioning 
properly and service is required. Contact 
an authorized dealer for service.
Sway Bar Fault Warning Light —
If Equipped
This light will illuminate when there is a 
fault in the sway bar disconnect system  
Úpage 166.
Tire Pressure Monitoring System (TPMS) 
Warning Light
The warning light switches on and a 
message is displayed to indicate that the 
tire pressure is lower than the 
recommended value and/or that slow 
pressure loss is occurring. In these cases, optimal 
tire life and fuel consumption may not be 
guaranteed. Should one or more tires be in the condition 
previously mentioned, the display will show the 
indications corresponding to each tire.
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 TPMS that illuminates a low tire 
pressure telltale when one or more of your tires is 
significantly underinflated. Accordingly, when the 
low tire pressure telltale illuminates, you should 
stop and check your tires as soon as possible and 
inflate them to the proper pressure. Driving on a 
significantly underinflated tire causes the tire to 
overheat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life, and 
may affect the vehicle’s handling and stopping 
ability.
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 underinflation has not reached the level to 
trigger illumination of the TPMS low tire pressure 
telltale.
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 upon subsequent vehicle 
start-ups 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.
WARNING!
Do not continue driving with one or more flat 
tires as handling may be compromised. Stop the 
vehicle, avoiding sharp braking and steering. If a 
tire puncture occurs, repair immediately using 
the dedicated tire repair kit and contact an 
authorized dealer as soon as possible.

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. Using 
aftermarket tire sealants may cause the Tire 
Pressure Monitoring System (TPMS) sensor to 
become inoperable. After using an aftermarket 
tire sealant it is recommended that you take 
your vehicle to an authorized dealer to have your 
sensor function checked.
