Fuel Gage
You will either have this fuel gage or one
very similar.
Your fuel gage tells you
about how much fuel you have left, when
the ignition is on. When the gage reads in
the yellow band, a warning chime will
sound and the
“CHECK GAGES”
warning light will
go on, if you have this
option.
Here are five things that some owners ask
about. None
of these indicate a problem
with your fuel gage:
0 At the service station, the gas pump
shuts off before the gage reads
“F”
(Full).
It takes a little more or less fuel to fill
up than the gage indicated. For
example, the gage may have indicated
the tank was half full, but
it actually
took a little more or less than half the
tank’s capacity to
fill the tank.
The gage moves a little when you
turn
a corner, speed up, or make a hard
stop.
The gage doesn’t go back to
“E”
(Empty) when you turn off the
ignition.
If you have the large span
(220”)
gage, the needle moves more for a
given amount of fuel. This does not
indicate excessive fuel consumption,
and is normal.
For your fuel tank capacity, see “Service
Station Information” on the last page of
this manual.

I
You can steer around the obstacle while
braking hard.
As you brake, your computer keeps
receiving updates
on wheel speed and
controls braking pressure accordingly.
Remember: Anti-lock doesn‘t change the
time you need to get your foot up to the
brake pedal.
If you get too close to the
vehicle
in front of you, you won’t have
time to apply your brakes
if that vehicle
suddenly slows
or stops. Always leave
enough room up ahead
to stop, even
though you have anti-lock brakes.
To Use Anti-Lock
Don’t pump the brakes. Just hold the
brake pedal down and let anti-lock work
for you.
You may hear a motor or clicking
noise during a hard stop, but
this is
normal.
Traction Control System
(OPTION)
Your vehicle may have a traction control
system that limits wheel spin. This is
especially useful
in slippery road
conditions. The system operates only
if it
senses that one or both of the front wheels
are spinning or beginning to lose traction.
When this happens, the system works the
front brakes and reduces engine power
(by shutting off fuel injectors and
managing spark) to
limit wheel spin.
You may feel the system working, or you
may notice some noise, but this is normal.
If your vehicle is in Cruise Control when
the traction control system begins
to limit
wheel spin, the Cruise Control will
auto~natically disengage. When road
conditions allow you to safely use
it
again, you may re-engage the Cruise
Control back on. (See “Cruise Control”
in
the Index.) The “TRACTION
OFF” warning
light
will come on when you turn the traction
control system off.
When the system is
on, this light will come
on to let you
know if there’s a problem with your
traction control system. See “Traction
Control System Warning Light” in’the
Index. When this warning light is on, the
system
will not limit wheel spin. Adjust
your driving accordingly.
The traction control system automatically
comes on whenever you start
your vehicle.
To limit wheel spin, especially
in slippery
road conditions, you should always leave
the system
on. But you can turn the
traction control system
off if you ever need
to. (You should
turn the system off if your
vehicle ever gets stuck
in sand. mud, ice or

Fuel
The 8th digit of your Vehicle
Identification Number (VIN) shows the
code letter for your engine.
You will find
the
VIN at the top left of your instrument
panel. (See “Vehicle Identification
Number”
in the Index.)
3800 Engine (Code L):
Use regular unleaded gasoline rated at 87
octane or higher. It should meet
specifications ASTM D48 14
in the U.S.
and CGSB 3.5-92 in Canada. These fuels
should have the proper additives,
so you
should not have to add anything to the
fuel. In
the
U.S. and Canada, it’s easy to be
sure you get the right kind
of gasoline
(unleaded). You’ll see
“UNLEADED”
right on the pump. And only unleaded
nozzles will fit into your vehicle’s filler
neck.
Be sure the posted octane is at least 87. If
the octane is less than 87, you may get a
heavy knocking noise when you drive. If
it’s bad enough, it can damage your
mgine.
[f you’re using fuel rated at 87 octane
or
higher and you still 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.
3800 Supercharged Engine (Code 1):
Use premium unleaded gasoline rated at
91 octane or higher.
You may use middle
grade or regular unleaded gasolines, but
your vehicle may not accelerate as well.
The gasoline you use should meet
specifications ASTM D4814
in the U.S.
and CGSB 3.5-92
in Canada. These fuels should
have the proper additives,
so you
should not have to add anything to the
fuel.
In the U.S. and Canada, it’s easy to be
sure you get the right kind of gasoline
(unleaded). You’ll see
“UNLEADED”
right on the pump. And only unleaded
nozzles will fit into your vehicle’s filler
neck.
Be sure the posted octane for premium is
at least 91 (at least 89 for middle grade
and 87 for regular). If the octane is.less
than
87, you may get a heavy knocking
noise when you drive. If it’s bad enough,
it can damage your engine.
If you’re using fuel rated at 9
1 octane or
higher and you still hear heavy knacking,
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.
What about gasoline with blending
materials that contain oxygen
(oxygenates), such as MTBE or alcohol?

Engine Accessory Belt
The 3800 (L27) engine uses an engine
accessory belt. This diagram shows the
features connected by the belt routing.

3800 Supercharged
(L67) Engine (OPTION)
Your Bonneville may have a 3800
Supercharged engine. The Supercharger is
a device which is designed to pump more
air 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,
increased 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 throttle
cruising, the excess air that the
’
Supercharger is pumping is routed,through
a bypass. All of these controls, working
together provide high performance
character and fuel efficiency
in the3800
V6 Supercharged engine.
The power steering pump uses a Remote
reservoir mounted on the throttle wd
cruise control cable bracket. See
“Maintenance Schedule”
in the Index for
when you should check the fluid:
