Hitches
It is important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough roads are
a few reasons why the right hitch is needed. Here
are some rules to follow:
The rear bumper on the vehicle is not intended for
hitches. Do not attach rental hitches or other
bumper-type hitches to it. Use only a
frame-mounted hitch that does not attach to the
bumper.
If holes need to be made in the body of the vehicle to
install a trailer hitch, then be sure to seal the holes
later when the hitch is removed. If the holes are not
sealed, deadly carbon monoxide (CO) from the
exhaust can get into the vehicle. SeeEngine Exhaust
on page 2-29. Dirt and water can, too.
Safety Chains
Chains should always be attached between the vehicle
and the trailer. Cross the safety chains under the
tongue of the trailer so that the tongue will not drop to
the road if it becomes separated from the hitch.
Instructions about safety chains may be provided by the
hitch manufacturer or by the trailer manufacturer.
Follow the manufacturer’s recommendation for attaching
safety chains and do not attach them to the bumper.
Always leave just enough slack so the rig can be turned.
And, never allow safety chains to drag on the ground.
Trailer Brakes
Because the vehicle has anti-lock brakes, do not try to
tap into the vehicle’s brake system. If that is done,
both brake systems will not work well, or at all.

Filling Your 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.
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. Keep
children away from the fuel pump; never let
children pump fuel.Turn the vehicle off to refuel.
The tethered fuel cap is located behind a hinged door
on the driver’s side of the vehicle. To remove the
fuel cap, turn it slowly counterclockwise. The fuel cap
has a spring in it; so if it is released too soon, it will
spring back.
5-7

When putting the fuel cap back on, turn it clockwise
until a click is heard. 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. SeeMalfunction
Indicator Lamp on page 3-35.
{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 3-35.
Filling a Portable Fuel Container
{CAUTION:
Never ll a portable fuel container while it is in
your vehicle. Static electricity discharge from
the container can ignite the gasoline vapor.
You can be badly burned and your vehicle
damaged if this occurs. To help avoid injury to
you and others:
Dispense gasoline only into approved
containers.
Do not ll a container while it is inside a
vehicle, in a vehicle’s trunk, pickup bed or
on any surface other than the ground.
Bring the ll nozzle in contact with the
inside of the ll opening before operating
the nozzle. Contact should be maintained
until the lling is complete.
Do not smoke while pumping gasoline.

To check or replace the engine air cleaner/lter, do the
following:
1. Loosen the screw and clamp on the air duct.
2. Lift the two clips
located on the top of
the lter assembly
to unlock the cover.
3. Disconnect the duct and reposition it while removing
the cover.
4. Pull out the lter.
5. Inspect or replace the lter if needed.
6. Reinstall the lter.
7. Push the two clips located on top of the lter
assembly to lock the cover.
{CAUTION:
Operating the engine with the air cleaner/lter
off can cause you or others to be burned. The
air cleaner not only cleans the air, it helps to
stop ame if the engine backres. If it is not
there and the engine backres, you could be
burned. Do not drive with it off, and be careful
working on the engine with the air cleaner/
lter off.
Notice:If the air cleaner/lter is off, a backre can
cause a damaging engine re. And, dirt can
easily get into your engine, which will damage it.
Always have the air cleaner/lter in place when you
are driving.

If the overheated warnings continue, there is one more
thing that can be done. Add the proper coolant
mixture directly to the radiator, but be sure the cooling
system is cool before this is done.
{CAUTION:
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and if you turn the radiator
pressure cap — even a little — they can come
out at high speed. Never turn the cap when the
cooling system, including the radiator pressure
cap, is hot. Wait for the cooling system and
radiator pressure cap to cool if you ever have
to turn the pressure cap.
How to Add Coolant to the Radiator
Notice:Your engine has a specic radiator
ll procedure. Failure to follow this procedure could
cause your engine to overheat and be severely
damaged.
Turn the pressure cap slowly counterclockwise until the
rst stop. Do not press down while turning the
pressure cap.

3.1. Clean the area around the engine oil ll tube
and cap before removing. Twist the oil ll
tube, with cap attached, counterclockwise
and remove it.3.2. If the vehicle has a supercharged engine,
remove the nut in the center of the cover

4. After the engine cools,
open the coolant air
bleed valve. The bleed
valve is located on
the thermostat
housing.
5. Fill the radiator with the
proper DEX-COOL
®
coolant mixture,
up to the base of the
ller neck. See
Engine Coolant on
page 5-26for more
information about the
proper coolant mixture.
If a stream of coolant is coming from an air bleed
valve, close the valve. Otherwise, close the
valve after the radiator is lled.6. Rinse or wipe any spilled coolant from the engine
and the compartment.
7. Replace the 3800 Series II V6 engine cover shield.
