192 Driving and Operating
Running the Vehicle
While Parked
It is better not to park with the
engine running.
If the vehicle is left with the engine
running, follow the proper steps to
be sure the vehicle will not move.
SeeShifting Into Park 0187 and
Engine Exhaust 0191.
If parking on a hill and pulling a
trailer, see Driving Characteristics
and Towing Tips 0262.
Diesel Particulate
Filter
The exhaust system has a Diesel
Particulate Filter (DPF) to reduce
vehicle emissions. On some
exhaust systems with a DPF, the
exhaust cooler mixes air with the
exhaust to lower the temperature
before it leaves the tailpipe.
The DPF, the tailpipe, and other
exhaust system components must
not be altered. Inspect regularly and
clean any mud or dirt from the
exhaust cooler, especially where the
exhaust cooler connects to the
tailpipe and the openings where
fresh air enters the cooler.
The DPF will clean itself as part of
normal operation. Several factors
including fuel consumed, hours of
engine operation, and miles driven
are monitored by the Engine Control
Module (ECM). The self-cleaning
occurs approximately once per tank
of fuel. Vehicles with the DPF have specific
fuel and engine oil requirements.
See
Fuel for Diesel Engines 0250
and
Engine Oil 0283.
Caution
Damage can occur to the DPF
components if the required Ultra
Low Sulfur Diesel (15 ppm sulfur
maximum) fuel and either CJ-4 or
CK-4 engine oil are not used.
This damage would not be
covered by the vehicle warranty.
Under certain conditions, such as
idling or very short trips, the
self-cleaning process has less
efficiency and cannot be completed.
To resolve this, continue driving
safely at a steady speed as close to
the posted speed limit as possible,
preferably without stopping, until the
message turns off. This can take up
to 30 minutes.

Driving and Operating 251
Caution
If the vehicle is accidentally
refueled with gasoline, do not
continue driving the vehicle.
Driving the vehicle will damage
the fuel system. Have the vehicle
towed to a qualified technician to
have the gasoline removed from
the tank and fuel system. Refuel
with Ultra Low Sulfur Diesel fuel.
It is also recommended to have
the fuel system flushed with Ultra
Low Sulfur Diesel, to ensure all
gasoline is removed.
Some conditions, such as dirty fuel,
may decrease fuel filter life and a
CHANGE FUEL FILTER message
may come on in the Driver
Information Center (DIC).
Climate Grade Diesel Fuels
At temperatures below 0 °C (32 °F),
avoid using biodiesel blends above
5% by volume. Using such a fuel
may cause fuel filter plugging, system gelling, and freezing, which
may adversely impact vehicle
starting.
Severe winter grade diesel fuel,
such as 1-D diesel fuel or Arctic
grade diesel fuel, can be used in
extreme cold temperatures (below
−18 °C or 0 °F); however, doing so
will reduce power and fuel economy.
Avoid using severe winter grade fuel
in warm or hot climates. It can result
in stalling, poor starting, and
damage to the fuel injection system.
Fuels improperly blended for cold
temperature operation may result in
restricted fuel filters. The vehicle is
equipped with a fuel heating system
to prevent gelling or waxing of
conventional diesel fuel and
biodiesel blends, but may not
prevent all cases.
In case of severe winter conditions,
the fuel filter may become clogged
by wax naturally present in the fuel.
To unclog it, move the vehicle to a
warm garage area and allow the
filter to warm up. The fuel filter may
need to be replaced. See
Fuel Filter
Replacement (Diesel) 0256.
Biodiesel
Biodiesel is a renewable fuel
produced from vegetable oils or
animal fats that have been
chemically modified to make it
compatible with diesel fuel.
Caution
Do not use home-made biodiesel
or home test kits because the
quality cannot be verified by
approved scientific methods. Do
not use raw vegetable oil or other
unmodified bio-oils, fats,
or blends of vegetable oil with
diesel. They could damage the
fuel system and engine, and
damages would not be covered
by the vehicle warranty.
Biodiesel Blends
Fuels with a biodiesel content up
to 20% by volume may be used
(e.g., named B20). Only use
biodiesel blends up to 20% by
volume that comply with your
country’s or region’ s fuel standards.

{Warning
Diesel fuel containing water is still
combustible. You or others could
be burned. If the fuel needs to be
drained, keep sparks, flames, and
smoking materials away from the
mixture.
Caution
Water in the diesel fuel can
corrode internal components of
the fuel system and lead to
severe damage. It can also
support fungus or bacteria
growth, which can damage the
fuel system and Fuel Operated
Heater (FOH), if equipped. Even
with a diesel fuel biocide, the fuel
system may still need to be
cleaned. Your dealer can advise
of the appropriate solution.(Continued)
Caution (Continued)
If the fuel tank needs to be
purged to remove water, see your
dealer or a qualified technician.
Improper purging can damage the
fuel system and block the FOH.
As an added precaution, drain the
diesel fuel filter of residual water at
every engine oil change. If the
WATER IN FUEL - CONTACT
SERVICE message comes on
frequently, even after draining water
from the fuel filter, see your dealer. Water in Fuel Troubleshooting

To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
. Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0287.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
Check the engine oil level regularly,
every 650 km (400 mi), especially
prior to a long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment Overview
0278 for the location.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
If a low oil Driver Information Center
(DIC) message displays, check the
oil level. If the oil is not low and the
low oil message remains on, take
the vehicle to your dealer for
service.
Follow these guidelines:
. To get an accurate reading, park
the vehicle on level ground.
Check the engine oil level after
the engine has been off for at
least two hours. Checking the
engine oil level on steep grades

containing used engine oil. See the
manufacturer's warnings about the
use and disposal of oil products.
Used oil can be a threat to the
environment. If you change your
own oil, be sure to drain all the oil
from the filter before disposal. Never
dispose of oil by putting it in the
trash or pouring it on the ground,
into sewers, or into streams or
bodies of water. Recycle it by taking
it to a place that collects used oil.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that indicates when to change the
engine oil and filter. This is based
on a combination of factors which
include engine revolutions, engine
temperature, and miles driven.
Based on driving conditions, the
mileage at which an oil change is
indicated can vary considerably. For
the oil life system to work properly,
the system must be reset every time
the oil is changed.When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A CHANGE ENGINE
OIL SOON message comes on.
Change the oil as soon as possible
within the next 1 000 km (600 mi).
It is possible that, if driving under
the best conditions, the oil life
system may indicate that an oil
change is not necessary for up to a
year. The engine oil and filter must
be changed at least once a year
and, at this time, the system must
be reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Display REMAINING OIL LIFE on the DIC menu. See Driver
Information Center (DIC) (Base
and Midlevel) 0124 or
Driver Information Center (DIC)
(Uplevel) 0130.
2. Press and hold
Vfor several
seconds while the Oil Life
display is active to reset the Oil
Life system.
3. REMAINING OIL LIFE 100% will be displayed when the oil
life system is successfully
reset.
The oil life system can also be reset
as follows: 1. Place the ignition in Service Mode. See Ignition Positions
0 179.
