Driver Behavior
Driving is an important
responsibility. Driver behavior, the
driving environment, and the
vehicle's design all affect how well a
vehicle performs.
Being aware of these factors can
help in understanding how the
vehicle handles and what can be
done to avoid many types of
crashes, including a rollover crash.
Most serious injuries and fatalities to
unbelted occupants can be reduced
or prevented by the use of seat
belts. In a rollover crash, an
unbelted person is significantly
more likely to die than a person
wearing a seat belt. In addition,
avoiding excessive speed, sudden
or abrupt turns, and drunken or
aggressive driving can help make
trips safer and avoid the possibility
of a crash.

Caution (Continued)
fuel system and engine, and
damages would not be covered
by the vehicle warranty.
Caution
Do not use blends containing
more than 20% biodiesel. Any
engine, fuel system, or exhaust
after-treatment system damage
would not be covered by the
vehicle warranty.
Biodiesel fuel quality degrades with
time and exposure to high
temperature quicker than Ultra Low
Sulfur Diesel fuel. More frequent
refueling provides the best
opportunity to have a supply of fresh
fuel. Storage at hot ambient
temperatures will accelerate
biodiesel degradation.
Owners who use very little fuel,
or who have vehicles stored for
extended periods of time, should avoid the use of biodiesel blended
fuels above 5% by volume. When
vehicles are stored for longer than
one month, they should be run out
of biodiesel to below one-quarter
tank, refueled with Ultra Low Sulfur
Diesel fuel, and driven at least
32 km (20 mi) before storage.
At temperatures below 0 °C (32 °F),
it is recommended to switch to Ultra
Low Sulfur Diesel fuel with no
biodiesel content, or to blends with
biodiesel containing less than 5% by
volume. At these extreme cold
temperatures, biodiesel blends
higher than 5% by volume may
cause fuel filter plugging and
system gelling, which can lead to
vehicle operability problems.
Fuels improperly blended for cold
temperature operation may result in
restricted fuel filters and degraded
vehicle performance. GM diesel
vehicles are equipped with a fuel
heating system to provide an extra
level of protection against filter
plugging from gelling or waxing of
conventional diesel fuel and
biodiesel blends. If the operating
temperature is far below the
temperature at which gelling or
waxing of the fuel occurs, the
system cannot prevent all cases of
filter plugging.
If the vehicle experiences a fuel
filter restriction, the on-board
monitoring system will alert the
driver that the fuel filter requires
service. The fuel filter, however, will
not prevent all damage caused by
poor quality biodiesel.
Cold Weather Operation
(Diesel)
In cold weather, 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) 0246.
At temperatures below 0 °C (32 °F),
it is recommended to avoid using
biodiesel blends above 5% blend.
This blend may cause fuel filter
plugging, system gelling, and

4. After a few attempts, if theengine still does not start, see
your dealer.
Running Out of Fuel
(Diesel)
{Warning
Diesel fuel is flammable. It could
start a fire if something ignites it,
and people could be burned. Do
not let it get on hot engine parts,
and keep matches or other
ignition sources away.
If the engine has stalled due to
running out of fuel, add at least
7.6 L (2 gal) of fuel if parked on a
level surface, or up to 18.9 L (5 gal)
of fuel if parked on a slope, and
perform the procedure under “Fuel
Priming” previously in this section.

The fuel filter is on the passenger
side, in front of the rear tire. 1. Drain any water from the filter. See “Removing Water from the
Fuel Filter” inWater in Fuel
(Diesel) 0243.
Keep the engine off until the
procedure is completed.
2. Apply the parking brake.

3. Remove the filter element cap by turning it counterclockwise.
4. Remove the filter element and o-rings. If there is any dirt on
the filter sealing surface, clean
it off.
5. Install the new filter element and o-rings.
6. Reinstall and tighten the filter cap to the housing.
7. Use the fuel filter priming procedure to prime the fuel
filter. See “Fuel Priming” in
Water in Fuel (Diesel) 0243.

Engine Oil Change
When the CHANGE ENGINE OIL
SOON message displays, have the
engine oil and filter changed within
the next 1 000 km/600 mi. If driven
under the best conditions, the
engine oil life system may not
indicate the need for vehicle service
for up to a year. The engine oil and filter must be changed at least once
a year and the oil life system must
be reset. Your trained dealer
technician can perform this work.
If the engine oil life system is reset
accidentally, service the vehicle
within 5 000 km/3,000 mi since the
last service. Reset the oil life
system when the oil is changed.
See
