2005 Pontiac Bonneville Owner ManualM
AUTOMATIC OVERDRIVE (D):This position is for
normal driving. If you need more power for passing, and
you are:
Going less than about 35 mph (55 km/h), push your
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You will shift down to the next gear and have more
power.
THIRD (3):This position is also used for normal driving.
However, it offers more power and lower fuel economy
than AUTOMATIC OVERDRIVE (D).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (D):
When driving on hilly, winding roads
When towing a trailer, so there is less shifting
between gears
When going down a steep hillSECOND (2):This position gives you more power but
lower fuel economy than THIRD (3). You can use
SECOND (2) on hills. It can help control your speed as
you go down steep mountain roads, but then you
would also want to use your brakes off and on.
Notice:Driving in SECOND (2) for more than
25 miles (40 km) or at speeds over 55 mph (90 km/h)
may damage the transaxle. Also, shifting into
SECOND (2) at speeds above 65 mph (105 km/h) can
cause damage. Drive in THIRD (3) or AUTOMATIC
OVERDRIVE (
X) instead of SECOND (2).
FIRST (1):This position gives you even more power
but lower fuel economy than SECOND (2). You can use
it on very steep hills, or in deep snow or mud. If the
shift lever is put in FIRST (1), the transaxle will not shift
into rst gear until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transaxle. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.

Malfunction Indicator Lamp
Service Engine Soon Light in the
United States or With V6 Engine in
Canada or Check Engine Light With
V8 Engine in Canada
Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition, and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The Service Engine Soon or Check Enginelight comes on to indicate that there is a problem and
service is required. Malfunctions often will be indicated
by the system before any problem is apparent. This
may prevent more serious damage to your vehicle. This
system is also designed to assist your service
technician in correctly diagnosing any malfunction.
Notice:If you keep driving your vehicle with this
light on, after awhile, your emission controls
may not work as well, your fuel economy may not
be as good, and your engine may not run as
smoothly. This could lead to costly repairs that may
not be covered by your warranty.
Notice:Modi cations made to the engine,
transaxle, exhaust, intake, or fuel system of your
vehicle or the replacement of the original tires with
other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.
Modi cations to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test. United States and V6 in
Canada
