Filling the Tank
{CAUTION:
Fuel vapor burns violently and a fuel re
can cause bad injuries. To help avoid
injuries to you and others, read and follow
all the instructions on the pump island.
Turn off your engine when you are
refueling. Do not smoke if you are near
fuel or refueling your vehicle. Do not use
cellular phones. Keep sparks, ames,
and smoking materials away from fuel.
Do not leave the fuel pump unattended
when refueling your vehicle. This is
against the law in some places. Do not
re-enter vehicle while pumping fuel.
Keep children away from the fuel pump;
never let children pump fuel.The tethered fuel cap is located behind a hinged
fuel door on the driver’s side of the vehicle.
If the vehicle has E85 fuel capability, a yellow cap
with the words “E85 or gasoline” can be seen.
To remove the fuel cap, turn it slowly
counterclockwise. It will require more effort to
turn the fuel cap on the last turn as you loosen it.

{CAUTION:
If you spill fuel and then something
ignites it, you could be badly burned.
Fuel can spray out on you if you open
the fuel cap too quickly. This spray can
happen if your tank is nearly full, and is
more likely in hot weather. Open the fuel
cap slowly and wait for any hiss noise to
stop. Then unscrew the cap all the way.
Be careful not to spill fuel. Do not top off or overll
the tank and wait a few seconds after you have
nished pumping before removing the nozzle.
Clean fuel from painted surfaces as soon as
possible. SeeWashing Your Vehicle on page 541.
When replacing the fuel cap, turn it clockwise
until it clicks. It will require more effort to turn
the fuel cap on the last turn as you tighten it.
Make sure the cap is fully installed. The diagnostic
system can determine if the fuel cap has been
left off or improperly installed. This would allow
fuel to evaporate into the atmosphere. See
Malfunction Indicator Lamp on page 250.The TIGHTEN GAS CAP message will be
displayed on the Driver Information Center (DIC)
if the fuel cap is not properly installed. See
DIC Warnings and Messages on page 267for
more information.
{CAUTION:
If a re starts while you are refueling,
do not remove the nozzle. Shut off the
ow of fuel by shutting off the pump
or by notifying the station attendant.
Leave the area immediately.
Notice:If you need a new fuel cap, be sure
to get the right type. Your dealer can get
one for you. If you get the wrong type,
it may not t properly. This may cause your
malfunction indicator lamp to light and
may damage your fuel tank and emissions
system. SeeMalfunction Indicator Lamp
on page 250.

Then, without shutting off the engine, follow
these steps:
The transmission
dipstick handle with
this graphic is located
at the rear of the engine
compartment, on the
passenger’s side of
the vehicle.
SeeEngine Compartment Overview on page 444
for more information on location.
1. Flip the handle up and then pull out the
dipstick and wipe it with a clean rag or
paper towel.
2. Push it back in all the way, wait three seconds
and then pull it back out again.3. Check both sides of the dipstick, and read the
lower level. The uid level must be in the COLD
area, below the cross-hatched area, for a cold
check or in the HOT or cross-hatched area for
a hot check. Be sure to keep the dipstick
pointed down to get an accurate reading.
4. If the uid level is in the acceptable range,
push the dipstick back in all the way; then
ip the handle down to lock the dipstick
in place.

Consistency of Readings
Always check the uid level at least twice using
the procedure described previously. Consistency
(repeatable readings) is important to maintaining
proper uid level. If readings are still inconsistent,
contact your dealer.
How to Add Automatic
Transmission Fluid
Refer to the Maintenance Schedule to determine
what kind of transmission uid to use. See
Recommended Fluids and Lubricants on page 574.
Using a funnel, add uid down the transmission
dipstick tube only after checking the transmission
uid while it is hot. A cold check is used only
as a reference. If the uid level is low, add only
enough of the proper uid to bring the level up to
the HOT area for a hot check. It does not take
much uid, generally less than one pint (0.5 L).
Do not overll.Notice:Use of the incorrect automatic
transmission uid may damage your vehicle,
and the damages may not be covered by
your warranty. Always use the automatic
transmission uid listed inRecommended
Fluids and Lubricants on page 574.
After adding uid, recheck the uid level as
described under “How to Check Automatic
Transmission Fluid,” earlier in this section.
When the correct uid level is obtained, push
the dipstick back in all the way; then ip the
handle down to lock the dipstick in place.
Engine Coolant
If your vehicle has the DURAMAX®Diesel engine,
see the DURAMAX®Diesel manual for more
information.
The cooling system in your vehicle is lled with
DEX-COOL
®engine coolant. This coolant is
designed to remain in your vehicle for ve years or
150,000 miles (240 000 km), whichever occurs rst,
if you add only DEX-COOL
®extended life coolant.
457

Page 467 of 618

{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can
boil before the proper coolant mixture will.
Your vehicle’s coolant warning system is
set for the proper coolant mixture. With
plain water or the wrong mixture, your
engine could get too hot but you would
not get the overheat warning. Your engine
could catch re and you or others could
be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.
Notice:In cold weather, water can freeze and
crack the engine, radiator, heater core and
other parts. Use the recommended coolant
and the proper coolant mixture.
{CAUTION:
You can be burned if you spill coolant
on hot engine parts. Coolant contains
ethylene glycol and it will burn if the
engine parts are hot enough. Do not spill
coolant on a hot engine.
1. You can remove
the coolant surge
tank pressure
cap when the
cooling system,
including the
coolant surge tank
pressure cap and
upper radiator hose,
is no longer hot.
Turn the pressure cap slowly counterclockwise
about one full turn. If you hear a hiss, wait for
that to stop. A hiss means there is still some
pressure left.

6. Turn on the low-beam headlamps and place a
piece of cardboard or equivalent in front of the
headlamp not being adjusted. This allows
only the beam of light from the headlamp
being adjusted to be seen on the at surface.
7. Locate the vertical headlamp aiming screws,
which are under the hood near each headlamp
assembly.
The adjustment screw can be turned with
a E8 Torx
®socket.8. Turn the vertical aiming screw until the
headlamp beam is aimed to the horizontal tape
line. Turn it clockwise or counterclockwise to
raise or lower the angle of the beam.
9. Make sure that the light from the headlamp is
positioned at the bottom edge of the horizontal
tape line. The lamp on the left (A) shows
the correct headlamp aim. The lamp on the
right (B) shows the incorrect headlamp aim.
10. Repeat Steps 7 through 9 for the opposite
headlamp.

2. Remove the
two screws from
the taillamp
assembly.
3. Pull the taillamp assembly rearward until you
disengage the outer pins on the taillamp
assembly from the vehicle.4. Press the release tab, if the bulb socket has
one, and turn the bulb socket
counterclockwise to remove it from the
taillamp assembly.
5. Pull the old bulb straight out from the bulb
socket.
6. Press a new bulb into the bulb socket and
insert the bulb socket into the taillamp
assembly. Turn the bulb socket clockwise into
the taillamp assembly until it clicks.
7. Reinstall the taillamp assembly making sure
to line up the pins with the vehicle.
