ECU PONTIAC BONNEVILLE 2003 Service Manual

The battery is located under the rear seat cushion.
To access the battery, see Removing the Rear Seat
Cushion on page
5-95. You don't need to access
the battery to jump start your vehicle. See
Jump Starting
on page
5-46.
A battery that isn't properly vented can let
sulfuric acid fumes into the area under the rear
seat cushion. These fumes can damage your
rear seat safety belt systems. You may not be
able to see this damage, and the safety belts
might not provide the protection needed
in a
crash. If a replacement battery
is ever needed,
it must be vented in the same manner as the
original battery. Always make sure that the
vent hose is properly reattached before reinstalling the seat cushion.
To be sure the vent hose (A) is properly attached, the
vent hose connectors
(B) must be securely reattached to
the vent outlets
(C) on each side of the battery, and
the vent assembly grommet
(D) must be secured to the
floor pan
(E).

Tire Chains
If your vehicle has P235/55R17 size tires, don’t
use tire chains, there’s not enough clearance.
Tire chains used on a vehicle without the proper amount of clearance can cause damage
to the brakes, suspension or other vehicle
parts. The area damaged by the tire chains
could cause you
to lose control of your vehicle
and you or others may be injured in a crash.
Use another type of traction device only if
its
manufacturer recommends it for use on your
vehicle and tire size combination and road
conditions.
Follow that manufacturer’s
instructions.
To help avoid damage to your
vehicle, drive slowly, readjust or remove the
device if it’s contacting your vehicle, and don’t
spin your wheels.
If you do find traction devices that will
fit,
install them on the front tires.
Notice: If your vehicle has a tire size other than
P235/55R17 size tires, use tire chains only where
legal and only when you must. Use only
SAE Class
”S” type chains that are the proper size for your
tires. Install them on the front tires and tighten them as tightly as possible with the ends securely
fastened. Drive slowiy and follow the chain manufacturer’s instructions. If you can hear the
chains contacting your vehicle, stop and retighten
them. If the contact continues,
slow down until
it stops. Driving too fast or spinning the wheels with
chains on will damage your vehicle.

1. Buckle the center passenger position safety belt,
then route the safety belts through the proper slots
in the seat cushion. Don’t let the safety belts get

4. Check to make sure the safety belts are properly
routed and that no portion of any safety belt is
trapped under the seat.
Also make sure the seat
cushion is secured.

The rear fuse block is
located below the rear seat
, on the driver’s side. The
~ rear seat cushion must be
removed to access the
fuse block. See

Pontiac has always exemplified quality and value in its
offering of motor vehicles. To enhance your ownership
experience, we and our participating dealers are
proud to offer Courtesy Transportation, a customer
support program for new vehicles.
The Courtesy Transportation program is offered to retail
purchase/lease customers in conjunction with the
Bumper-to-Bumper coverage provided by the New
Vehicle Limited Warranty. Several transportation options
are available when warranty repairs are required.
This will reduce your inconvenience during warranty
repairs.
Plan Ahead When Possible
When your vehicle requires warranty service, you
should contact your dealer and request an appointment.
By scheduling a service appointment and advising
your service consultant of your transportation needs,
your dealer can help minimize your inconvenience.
If your vehicle cannot be scheduled into the service
department immediately, keep driving it until it can be
scheduled for service, unless, of course, the problem is
safety-related.
If it is, please call your dealership, let
them know this, and ask for instructions.
If the dealer requests that you simply drop the vehicle
off for service, you are urged to do
so as early in
the work day as possible to allow for same day repair.
