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.
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
If the WATER IN FUEL - CONTACT

If no water can

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.

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.
FWD Shown, AWD Similar
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 0195. 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 0195. 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. 4. After a few attempts, if the
engine 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) 0264.
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) 0264. 8. Start the engine and let it idle
for 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)
0 142 orDriver Information
Center (DIC) (Uplevel) 0147.
Filling the Tank
(Gasoline)
{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, read and follow
all the instructions on the
fuel pump island.
. Turn off the engine when
refueling.

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 0298.
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.
