2004 BUICK PARK AVENUE lock

Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make
body insulators from newspapers, burlap bags, rags,
oor mats — anything you can wrap around
yourself or tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
{CAUTION:
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide)
gas to get inside. CO could overcome you and
kill you. You can not see it or smell it, so you
might not know it is in your vehicle. Clear away
snow from around the base of your vehicle,
especially any that is blocking your exhaust pipe.
And check around again from time to time to be
sure snow does not collect there.
Open a window just a little on the side of the
vehicle that is away from the wind. This will help
keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly.
This uses less fuel for the heat that you get and it keeps
the battery charged. You will need a well-charged battery
to restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.

Safety Chains
You should always attach chains between your vehicle
and your 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 you can turn
with your rig. And, never allow safety chains to drag
on the ground.
Trailer Brakes
Be sure to read and follow the instructions for the trailer
brakes so you will be able to install, adjust and
maintain them properly.
Because you have anti-lock brakes, do not try to tap
into your vehicle’s brake system. If you do, both brake
systems will not work well, or at all.
Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you will want to
get to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the trailer.
And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check all trailer hitch parts and
attachments, safety chains, electrical connector, lamps,
tires and mirror adjustment. If the trailer has electric
brakes, start your vehicle and trailer moving and then
apply the trailer brake controller by hand to be sure
the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer
brakes are still working.

While refueling, hang the tethered fuel cap from the
hook on the fuel door.
To remove the fuel cap, turn it slowly to the left
(counterclockwise). The fuel cap has a spring in it;
if you let the cap go too soon, it will spring back to
the right.
{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. Don’t top off or overll your
tank and wait a few seconds after you’ve nished
pumping before you remove the nozzle. Clean fuel from
painted surfaces as soon as possible. SeeCleaning
the Outside of Your Vehicle on page 5-93.
5-8

When you put the fuel cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make sure
you fully install the cap. 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 3-41.
{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. See “Malfunction Indicator Lamp” in the
Index.
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.

Checking the Fluid Level
Prepare your vehicle as follows:
Park your vehicle on a level place. Keep the engine
running.
With the parking brake applied, place the shift lever
in PARK (P).
With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds in each range. Then, position the shift
lever in PARK (P).
Let the engine run at idle for three to ve minutes.
Then, without shutting off the engine, follow these steps:
The transaxle uid dipstick
top is a round, red loop and
is located next to the brake
master cylinder reservoir
behind the engine block.
SeeEngine Compartment
Overview on page 5-12
for more information
on location.1. 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
cross-hatched area.
4. If the uid level is in the acceptable range,
push the dipstick back in all the way.

How to Add Coolant to the Radiator
1. You can remove the radiator pressure cap when
the cooling system, including the radiator pressure
cap and upper radiator hose, is no longer hot.
Turn the pressure cap slowly counterclockwise until
it rst stops. Do not press down while turning the
pressure cap.
If you hear a hiss, wait for that to stop. A hiss
means there is still some pressure left.2. Then keep turning the pressure cap, but now push
down as you turn it. Remove the pressure cap.
3. Remove the 3800 Series II V6 engine cover shield
to access the bleed valve.

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 you have the supercharged engine,
remove the nut in the center of the cover
shield.3.3. Lift the engine cover shield at the front, slide
the catch tab out of the engine bracket and
remove the cover shield.
3.4. Put the oil ll tube, with cap attached, in the
valve cover oil ll hole until you are ready to
replace the cover shield.
4. After the engine cools,
open the coolant air
bleed valve. There is
one bleed valve.
It is located on the
thermostat housing.
