collected by the diesel particulate filter,
ambient temperature and altitude, manual
regeneration lasts approximately 30
minutes.

WARNING LAMPS
If filter service is required, the
engine control system warning
lamp illuminates in the
information display. If there are any issues with the
diesel particulate filter system,
the engine control system
warning lamp and a service

illuminate to inform you that
your vehicle requires service. Have your
vehicle checked as soon as possible.
DIESEL PARTICULATE FILTER – INFORMATION MESSAGES Action
Message
Your vehicle has entered the cleaning mode. Various engineactions will raise the exhaust temperature in the Diesel
Particulate Filter system to burn off the particles (exhaust
soot). After the vehicle burns the particles off, the exhaust temperature will return to normal levels. This message is NORMAL.
Exhaust Filter Cleaning
The diesel particulate filter is full of particles (exhaust soot)
and you are not operating the vehicle in a manner that allows normal cleaning. Drive the vehicle above 30 mph (48 km/h)
until the message turns off.

Driving without refilling, replacing
contaminated diesel exhaust fluid, or
having the selective catalytic reduction
system repaired results in the following
actions as required by the California Air
Resources Board (CARB) and the U.S.
Environmental Protection Agency (EPA):
•
Within a preset distance to empty,
speed is limited upon vehicle restart.
Prior to this occurring a message
appears in the information display.
• Further vehicle operation without
refilling or replacing contaminated
diesel exhaust fluid causes the engine
to enter an idle-only condition. This
only occurs upon vehicle refueling,
vehicle idling in park for 1 hour, or
engine shutdown for 10 minutes or
more and is indicated by a message in
the information display indicating
required actions to resume normal
operation. It is required to add a
minimum of 1.0 gal (3.8 L) of diesel
exhaust fluid to the tank to exit the
idle-only condition, but your vehicle is
still in the speed-limiting mode until
you refill the tank completely.
Note: For vehicle speed limiting or idle-only
condition, normal vehicle operation resumes
when you refill the diesel exhaust fluid tank
or repair the contaminated system. If the
system is contaminated or inoperative, have
your vehicle checked as soon as possible. SELECTIVE CATALYTIC
REDUCTION SYSTEM
REQUIREMENTS Only use diesel exhaust fluid that is
certified by the American Petroleum
Institute (API).
You can purchase diesel exhaust fluid at
an authorized dealer, or contact roadside
assistance for help in finding a retailer that
sells diesel exhaust fluid.
Note:
Non-certified diesel exhaust fluid use
can cause damage that your Warranty may
not cover
SELECTIVE CATALYTIC
REDUCTION SYSTEM
GUIDELINES
• Diesel exhaust fluid is non-flammable,
non-toxic, colorless and water-soluble
liquid.
• In order for the system to operate
correctly you must maintain the diesel
exhaust fluid level.
• Do not overfill the diesel exhaust fluid
tank.
• Diesel exhaust fluid is corrosive.

•
Avoid spilling diesel exhaust fluid on
painted surfaces, carpeting or plastic
components. Immediately wipe away
any diesel exhaust fluid that has spilled
with a damp cloth and water. If it has
already crystallized, use warm water
and a sponge.
• Do not store the diesel exhaust fluid
bottle in your vehicle. If it leaks it could
cause damage to interior components
or release an ammonia odor inside your
vehicle.
• Do not re-use the diesel exhaust fluid
container once it is emptied.
• Store diesel exhaust fluid out of direct
sunlight and in temperatures between
23–68°F (-5– 20°C).
• The system has a diesel exhaust fluid
quality sensor. Dilution of diesel
exhaust fluid or use of any other liquid
in the selective catalytic reduction
system leads to a diesel exhaust fluid
system fault, eventually leading to the
vehicle only operating in idle-only
mode.
• Do not dilute diesel exhaust fluid with
water or any other liquid. FILLING THE SELECTIVE
CATALYTIC REDUCTION
SYSTEM TANK
FILLING THE SELECTIVE
CATALYTIC REDUCTION SYSTEM
TANK IN COLD WEATHER
Diesel exhaust fluid may freeze if the
ambient temperature is below 12°F (-11°C).
Your vehicle has a preheating system
which allows diesel exhaust fluid to
operate below
12°F (-11°C). If you do not
use your vehicle for an extended period
when the ambient temperature is below
12°F (-11°C)
, the fluid in the tank may
freeze. If the tank is overfilled and the fluid
freezes it may cause damage that your
Warranty will not cover.
FILLING THE SELECTIVE
CATALYTIC REDUCTION SYSTEM
TANK USING A FUEL STATION
PUMP
Filling the diesel exhaust fluid tank using
a fuel station pump is similar to refueling
your vehicle.
1. Fully open the fuel filler door. 2. Remove the diesel exhaust fluid tank
filler cap.

PRECAUTIONS
WARNING: Apply the parking
brake, shift into park (P), switch the
ignition off and remove the key before
you leave your vehicle. Failure to follow
this instruction could result in personal
injury or death. WARNING:
Do not use tow/haul
when the road surface is slippery. Failure
to follow this instruction could result in
the loss of control of your vehicle. WARNING:
When your vehicle is
stationary, keep the brake pedal fully
pressed when shifting gears. Failure to
follow this instruction could result in
personal injury, death or property
damage. WARNING:
Do not apply the brake
pedal and accelerator pedal
simultaneously. Applying both pedals
simultaneously for more than a few
seconds will limit engine performance,
which may result in difficulty maintaining
speed in traffic and could lead to serious
injury.
