If you keep pace with the traffic and
allow realistic following distances, you
will eliminate a lot of unnecessary
braking. That means better braking and
longer brake life.
If your engine ever stops while you’re
driving, brake normally but don’t
pump your brakes. If you do, the
pedal may get harder to push down. If
your engine stops, you will still have
some power brake assist. But you will
use it when you brake. Once the
power assist is used up, it may take
longer to stop and the brake pedal will
be harder to push.
Anti-Lock Brakes (ABS) (OPTION)
If your Pontiac has this system, it has an
advanced electronic braking system
that
will help prevent skidding.
If you have an anti-lock brake system
(ABS), the brake pedal will say so.

And this light on the instrument panel
will
go on when you start your vehicle.
When you start your vehicle and begin
to drive away you may hear a
momentary motor or clicking noise and
you may even notice that your brake
pedal moves a little while this is going
on. This is the ABS system testing itself.
If you have your foot on the brake
pedal, this check won't happen until the
vehicle goes about
4 mph (6 ltm/h) or
until you take your foot off the brake
pedal.
After
an ABS stop, you may hear a
clicking noise the next time the vehicle
goes about 4 mph (6 ltdh).

Parking on Hills
You really should not park your vehicle,
with a trailer attached, on a hill.
If
something goes wrong, your rig could
start to move. People can be injured,
and both your vehicle and the trailer
can be damaged.
But if you ever have to park your rig on
a hill, here’s how to do it:
1. Apply your regular brakes, but don’t
shift into
P (Park) yet.
2. Have someone place chocks under
the trailer wheels.
3. When the wheel chocks are in place,
release the regular brakes until the
chocks absorb the load.
4. Reapply the regular brakes. Then
apply your parking brake, and then
shift to
P (Park).
5. Release the regular brakes.
When You Are Ready to Leave After
Parking

1. Apply your regular brakes and hold
the pedal down while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear
4. Stop and have someone pick up and

store the choclts.
Maintenance When Trailer Towing
Your vehicle will need service more
often when you’re pulling a trailer. See
the Maintenance Schedule for more on
this. Things that are especially
important in trailer operation
are
automatic transaxle fluid (don’t
overfill), engine oil, belts, cooling
system, and brake adjustment. Each
of
these is covered in this manual, and the
Index will help you find them quickly. If
you’re trailering, it’s a good idea to
review these sections before you start
your trip.
Check periodically to see that all hitch
nuts and bolts are tight.
