terminal of the vehicle with the dead battery. Use a
remote positive
(+) terminal if the vehicle has one.

positive
(9) terminal if
the vehicle has one.
NOW connect the
black negative (-) cable
to the good battery’s
negative (-) terminal.
Don’t let the other end

Things you might add to the outside of your vehicle can
affect
the airdaow around it. This may cause wind noise
and affect windshield washer performance. Check with
your dealer before adding equipment to the outside
of
your vehicle. The
8th digit sf your vehicle
identification number
(Vm) shows the code lettee for your engine. You will
find the VIN at the top left of your instmment panel.
(See “Vehicle Identifkation Number’’ in the Endex.)
If you have the 3800 engine (VIN Code use regula
unleaded gasoline rated
at 87 octane or higher. If you’re
using fuel rated
at the recommended octane or higher
and
you hear heavy knocking, your engine needs
service. But don’t
worry if YOU hear a little pinging
noise when you’re accelerating or driving
up a hill.
That’s normal, and YOU don’t have to buy a higher
octane fuel
to get rid of pinging. It’s the heavy, constant
knock
that means you have a problem.
If you have the 3800 Supercharged engine (VHN
Code I), use premium unleaded gasoline rated at
91 octane or higher. With the 3800 Supercharged
engine, in
an emergency, you may be able to use a
lower QC~XE -- as low as 87 -- if heavy knocking does
not occur. If you are using 91 cx higher octane unleaded
gasoline and
YOU hear heavy knocking, your engine
needs service.

Your vehicle may have 2 3800 Sqercharged engine.
Supercharging, rather
than turbocharging, emphasizes
smooth, refined power.
The supercharger is a device which is designed to pump
more ais into the engine than it would normally use.
This air mixed with fuel creates increased engine power.
Since the supercharger
is a pump and is driven from an
engine
accessory drive belt, iwreased pressure is
available at all driving conditions.
The Powertrain Control Module (PCM) works with a
vacuum control to regulate the increased pressure
required during specific driving conditions. When this
increased pressure or boost is not desired, such as during
idling and light tfarsttIe cruising, the excess air that the
supercharger is pumping is routed through a bypass.
AB1 sf these controk working together provide high
performance character and fuel efficiency in the
3800 V6 Supercharged engine.
The power steering pump and reservoir are mounted on
the rear (driver’s side) sf the engine biock. See
“Maintenance Schedule”
in the Index for when you
should check the fluid.

Change
both the fluid a.nd filter every 50,000 miles
(83 080 Ian) if the vehicle is mainly driven rander one
or more of these conditions:
8 In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.

............. ............. the brake master
cylinder behind
the
engine block. Pull out
the dipstick and wipe
it with a clean rag or
paper towel.
3. Check both sides of the dipstick, and read the
lower level. The fluid 'level
must be in the
cross-hatched area.
2. Push it back in all the way, wait thee seconds and 4. If the fluid level is in the acceptable range, push
then pull it back out again. the dipstick back in a11 the way.

Refer to the Maintenance Schedule to determine what
kind
of transaxle fluid to use. See “Recommended
Fluids
md Eubricmts” in the Index.
If the fluid level is low, add only enough of the proper
fluid
to bring the level into the cross-hatched area on
the dipstick.
I. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at the
dipstick hole
to bring it to the proper level.
It doesn’t
take much fluid, generally less than one

The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 MI0 h) whichever occurs first, if you add only
DEX-COOL“ extended life coolant,
The following explains
your coding system and
how to add coolant when it is low. If YOU have a
problem with engine overheating, see “Engine
Overheating”
in the Index.
A 50/50 mixture of water and DEX-COOL’
coolant will:
J
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 OF 129 ” C).
Protect against rust and corrosion.
Help keep the proper engine temperature.

1 f ENG. COOLANT LOW CHECK LEVEL
Turning the radiator pressure cap when the
engine and radiator
are hot can allow steam
and scalding liquids to blow out and burn yon
badly. With the codant recovery tank, you will
almost never have fO add coolant at the radiator.
Never turn the radiator pressure cap -- even a
little -- when the engine sand radiator are hot.
You can be burned if you spill cooiant QPB hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Don't spill coolant on a hot engine.
