displays and
stays on. Drain the fuel
filter
immediately.
If no water can
be drained, and
the temperature
is below
freezing, then
water may be
frozen in the
filter. Move the
vehicle to a
warm location to
thaw the water,
then drain the
fuel. If water still
does not drain,
see your dealer. Problem
Recommended
Action
Immediately
after refueling,
message
displays and
stays on. A large amount
of water is in the
fuel tank. Drain
the fuel filter
immediately.
If the message
stays on or
comes back on
without
refueling, then
fuel tank purging
is required. See
your dealer.
If the message
displays and the
engine stalls or
runs rough, do
not drive until
the water
contaminated
fuel is drained.Caution
Driving with this message on can
damage the fuel injection system
and the engine. If the message
comes on right after a refuel,
water was pumped into the fuel
tank. Turn off the engine and
drain the water immediately.
Removing Water from the Fuel
Filter
To drain water: 1. Turn the engine off and apply the parking brake.
2. Place a container under the filter drain valve, which is on
the bottom of the fuel filter.

3. Turn the drain plug counterclockwise using a
suitable tool.
4. With the engine off, press and hold ENGINE START/STOP
without applying the brake for
five seconds to place the
vehicle in Service Mode. See
Ignition Positions 0179. Wait
approximately five seconds,
and then press ENGINE
START/STOP again to turn it
off. This operation will enhance
water flow out of the filter. The filter is drained as soon as
diesel fuel emerges from
the port.
5. Retighten the drain plug by turning it clockwise.
6. Properly dispose of the water contaminated fuel.
7. Start the engine and let it run for a few minutes. During the
draining process, air may have
entered the fuel system. If the
engine stalls, the fuel system
may need to be primed. See
“Fuel Priming” following.
Fuel Priming
For the fuel system to work properly,
air cannot be in the fuel lines. If air
gets in, the engine may not start
and the fuel lines will need to be
primed before operating the vehicle.
If air is present, the following may
have happened:
. The vehicle ran out of fuel.
. The fuel filter was removed.
. The fuel lines were removed or
disconnected. .
The fuel filter water drain valve
was opened while the engine
was running.
To prime the fuel lines: 1. With the engine off, press and hold ENGINE START/STOP
without applying the brake for
five seconds to place the
vehicle in Service Mode. See
Ignition Positions 0179. Wait
approximately five seconds
and press ENGINE START/
STOP again to turn it off. Do
this step three times or more
while the engine is off.
2. Press and hold ENGINE START/STOP while applying
the brake for a maximum of
40 seconds at a time, with
five seconds between attempts,
until the engine starts. If the
engine tries to run, but does
not run smoothly, increase the
rpm’s slightly by using the
accelerator pedal. This will help
force air through the system.
3. Repeat Step 2 if the engine stalls and will not restart.

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.
Fuel Filter Replacement
(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.
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) 0252.
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) 0252.

8. Start the engine and let it idlefor five minutes. Check the fuel
filter and air bleed valve for
leaks.
9. Reset the fuel filter monitor. See Driver Information Center
(DIC) (Base and Midlevel)
0 124 or
Driver Information Center (DIC)
(Uplevel) 0130.
Filling the Tank
(Gasoline)
An arrow on the fuel gauge
indicates which side of the vehicle
the fuel door is on. See Fuel Gauge
0 111.
{Warning
Fuel vapors and fuel fires burn
violently and can cause injury or
death.
Follow these guidelines to help
avoid injuries to you and others:
(Continued)
Warning (Continued)
.Read and follow all the
instructions on the fuel
pump island.
. Turn off the engine when
refueling.
. Keep sparks, flames, and
smoking materials away
from fuel.
. Do not leave the fuel pump
unattended.
. Avoid using electronic
devices while refueling.
. Do not re-enter the vehicle
while pumping fuel.
. Keep children away from
the fuel pump and never let
children pump fuel.
. Before touching the fill
nozzle, touch a metallic
object to discharge static
electricity from your body.
(Continued)
Warning (Continued)
.Fuel can spray out if the fill
nozzle is inserted too
quickly. This spray can
happen if the tank is nearly
full, and is more likely in hot
weather. Insert the fill nozzle
slowly and wait for any hiss
noise to stop before
beginning to flow fuel.
To open the fuel door, push and
release the rearward center edge of
the door.

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
Engine Oil Life System 0287.
On vehicles with diesel engines, it is
recommended to drain the diesel
fuel filter of water when the oil is
changed or when the WATER IN
FUEL CONTACT SERVICE
message displays.
Air Conditioning Desiccant
(Replace Every Seven Years)
The air conditioning system requires
maintenance every seven years.
This service requires replacement of
the desiccant to help the longevity
and efficient operation of the air
conditioning system. This service
can be complex. See your dealer.
Tire Rotation and Required
Services Every 12 000 km/
7,500 mi
Rotate the tires, if recommended for
the vehicle, and perform the

(1) Or every two years, whichever
comes first. More frequent
passenger compartment air filter
replacement may be needed if
driving in areas with heavy traffic,
poor air quality, high dust levels,
or environmental allergens.
Passenger compartment air filter
replacement may also be needed if
there is reduced airflow, window
fogging, or odors. Your GM dealer
can help determine when to replace
the filter.
(2) Visually check all fuel and vapor
