WHAT IS THE CABIN AIR
FILTER
The cabin air filter improves the quality of
air in your vehicle by trapping dust, pollen
and other particles.
REPLACING THE CABIN AIR
FILTER
Replace the filter at regular intervals. See
Scheduled Maintenance (page 664).
The cabin air filter is behind the glove
compartment.
To remove the lower glove compartment
and access the filter:
1. Open the glove compartment. 2. Press the tab on each side.
3. Fully lower the glove compartment.
4. Pull the glove compartment toward
you.

WHAT IS THE DIESEL
PARTICULATE FILTER
The diesel particulate filter is part of your
vehicle's emissions system and filters
harmful diesel particulates from the
exhaust gas.
HOW DOES THE DIESEL
PARTICULATE FILTER WORK
The diesel particulate filter reduces
emissions by trapping exhaust particles
before they reach the tailpipe. The system
must periodically clean the exhaust
particles that gather inside the filter. This
is carried out in three ways, passive
regeneration, active regeneration and
manual regeneration.
Passive Regeneration
In passive regeneration, the normal
exhaust system temperature cleans the
filter by oxidizing the soot. Cleaning occurs
during normal vehicle operating conditions
due to driving patterns.
Active Regeneration
Once the diesel particulate filter is full,
active regeneration raises the exhaust
temperature to eliminate the particles.
When the engine control module detects
that the diesel particulate filter is nearly
full of particulates, and you are not
operating your vehicle in a manner to allow
effective regeneration, messages appear
in the information display as a reminder
for you to drive your vehicle in order to
clean the diesel particulate filter. If you
drive your vehicle in a manner to allow
effective regeneration, the information
display shows a cleaning exhaust filter
message.
DIESEL PARTICULATE FILTER
PRECAUTIONS WARNING: Do not park or idle your
vehicle over dry leaves, dry grass or other
combustible materials. The regeneration
process creates very high exhaust gas
temperatures and the exhaust will
radiate a considerable amount of heat
during and after regeneration and after
you have switched the engine off. This is
a potential fire hazard. WARNING:
When the Exhaust
Filter Cleaning message appears in the
information display, do not park near
flammable materials, vapors or
structures until filter cleaning is
complete. WARNING:
The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the diesel oxidation
catalytic converter or the diesel
particulate filter. The diesel oxidation
catalytic converter and the diesel
particulate filter heat up to very high
temperatures after only a short period
of engine operation and remain hot after
you switch the engine off.
Note: Avoid running out of fuel.
Note: During regeneration at low speed or
engine idle, you may smell a hot metallic
odor and could notice a clicking metallic
sound. This is due to high temperatures
reached during regeneration and is normal.
Note: Changes in the engine or exhaust
sound may be heard during the regeneration
process.

WHAT IS THE CATALYTIC
CONVERTER
The catalytic converter is part of your
vehicle's emissions system and filters
harmful pollutants from the exhaust gas.
CATALYTIC CONVERTER
PRECAUTIONS
WARNING: Do not park, idle or
drive your vehicle on dry grass or other
dry ground cover. The emission system
heats up the engine compartment and
exhaust system, creating the risk of fire. WARNING:
The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short
period of engine operation and stays hot
after the engine is switched off. WARNING:
Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes.
To avoid damaging the catalytic converter:
• Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables. See Jump
Starting the Vehicle
(page 486). •
Use the correct fuel.
See Fuel and
Refueling (page 255).
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Do not make any unauthorized
changes to your vehicle or engine. By law,
vehicle owners and anyone who
manufactures, repairs, or services a fleet of
vehicles are not permitted to intentionally
remove an emission control device or
prevent it from working.
CATALYTIC CONVERTER –
TROUBLESHOOTING
CATALYTIC CONVERTER –
WARNING LAMPS
Your vehicle has an on-board diagnostics
system that monitors the emission control
system. If any of the following warning
lamps illuminate, this may indicate that
the on-board diagnostics system has
detected an emission control system
malfunction. Continuing to drive your vehicle may cause
reduced power or the engine to stop.
Failure to respond to a warning lamp may
cause damage that your vehicle Warranty
may not cover. Have your vehicle checked
as soon as possible.

DRIVING THROUGH WATER
LIMITATIONS - RAPTOR
Maximum Wading
Depth
Model
32 in (810 mm)
All.
When you are driving though water do not
exceed 4 mph (7 km/h).
WATER WADING WARNING:
Do not attempt to
cross a deep, fast flowing body of water.
Failure to follow this instruction could
result in the loss of control of your
vehicle, personal injury or death.
As the water depth increases, you must
reduce your vehicle speed to avoid
potential vehicle damage. •
Always determine the depth before
attempting a water crossing. Never
drive through water that is higher than
the bottom of the wheel hubs.
• Slowly proceed and avoid splashing
water any more than is necessary. •
Be aware that obstacles and debris
may be beneath the water ’s surface.
• Keep the doors fully closed during the
water crossing.
• After driving through water and as soon
as it is safe to do so check the brakes,
horn, lights, and steering wheel to
confirm those systems are functioning
properly.
Note: Engine damage can occur if water
enters the air filter.
OFF-ROAD DRIVING AIDS -
RAPTOR
Selecting an Off-Road Drive Mode
Using the appropriate drive mode increases
your vehicle's control. See
Drive Mode
Control (page 371).
Using Four-Wheel Drive
Your vehicle has a four-wheel drive system
that offers various modes to help you
optimize traction on any off-road surface.
See
Four-Wheel Drive (page 291).
Using the Cameras Off-Road
Use the 360 degree camera to enhance
your off-road experience. See 360 Degree
Camera
(page 342).
Using the Rear Differential Lock
When engaged, the rear differential lock
provides additional traction to your vehicle
by forcing the two rear wheels to turn at
the same speed.
Note: Rear differential lock is only available
when the vehicle is in 4H or 4L. See
Electronic Locking Differential (page 301).
