Making Turns
I NOTICE:
Making very sharp turns while trailering could cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you’re turning with a trailer, make wider
turns than normal.
Do this so your trailer won’t
strike soft shoulders, curbs, road signs, trees or other
objects. Avoid jerky or sudden maneuvers. Signal
well in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your Buick dealer. The arrows on your instrument
panel will flash whenever
you signal a turn or lane
change. Properly hooked up, the trailer lamps will also
flash, telling other drivers you’re about
to turn, change
lanes or stop. When towing
a trailer, the arrows on your instrument
panel will flash for turns even if the bulbs on the trailer
are burned
out. Thus, you may think drivers behind
you are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down, you might have
to use your brakes so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around
45 mph (70 km/h) to reduce the
possibility
of engine and transaxle overheating.
If you are towing a trailer that weighs more than
1,000 lbs. (450 kg) and you have an automatic transaxle
with overdrive, you may prefer to drive in
THIRD (3)
instead of AUTOMATIC OVERDRIVE (@I). An
overdrive transmission is required if towing a trailer more
than
1,000 lbs. (450 kg).

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
2. Have someone place chocks under the trailer wheels.
PARK
(P) yet.
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 PARK (P).
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on
a Hill
1. Apply your regular brakes and hold the pedal down
while
you:
m Start your engine;
0 Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
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, belt, 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.
