Parking on Hills
{WARNING
Parking the vehicle on a hill
with the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill:
1. Press the brake pedal, but do not shift into P (Park) yet. Turn
the wheels into the curb if facing
downhill or into traffic if facing
uphill.
2. Have someone place chocks under the trailer wheels. 3. When the wheel chocks are in
place, release the brake pedal
until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking brake and shift
into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal while you:
.Start the engine.
.Shift into a gear.
.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
The vehicle needs service
more often when pulling a trailer.
See the Maintenance Schedule
booklet for more information.
Things that are especially important
in trailer operation are automatic
transmission fluid, engine oil, axle
lubricant, belts, cooling system and
brake system. Inspect these before
and during the trip.
Check periodically to see that all
hitch nuts and bolts are tight.
Engine Cooling when Trailer
Towing
The cooling system may temporarily
overheat during severe operating
conditions. See Engine Overheating
on page 10‑21.

10-98 Vehicle Care
Fabric/Carpet
Use a vacuum cleaner with a soft
brush attachment to remove dust
and loose dirt. A canister vacuum
with rotating brushes in the nozzle
may only be used on floor carpet
and carpeted floor mats. For soils,
always try to remove them first with
plain water or club soda. Before
cleaning, gently remove as much of
the soil as possible using one of the
following techniques:
.For liquids: gently blot the
remaining soil with a paper
towel. Allow the soil to absorb
into the paper towel until no
more can be removed.
.For solid dry soils: remove as
much as possible and then
vacuum.
To clean:
1. Saturate a lint-free, clean white cloth with water or club soda.
2. Remove excess moisture. 3. Start on the outside edge of the
soil and gently rub toward the
center. Continue cleaning, using
a clean area of the cloth each
time it becomes soiled.
4. Continue to gently rub the soiled area.
5. If the soil is not completely removed, use a mild soap
solution and repeat the cleaning
process with plain water.
If any of the soil remains, a
commercial fabric cleaner or spot
lifter may be necessary. Test a
small hidden area for colorfastness
before using a commercial
upholstery cleaner or spot lifter.
If the locally cleaned area gives
any impression that a ring formation
may result, clean the entire surface.
A paper towel can be used to blot
excess moisture from the fabric or
carpet after the cleaning process.
Leather
Leather, and lighter colored leather
in particular, will need more frequent
cleaning to prevent the buildup of
dust, dirt, and colors transferred
from other items so that these do
not become permanent stains.
To remove dust, a soft cloth
dampened with water can
be used. If a more thorough
cleaning is necessary, a soft
cloth dampened with a mild soap
solution can be used. Your dealer
has a GM approved leather cleaner
available that provides superior
cleaning performance when used
regularly on finished automotive
leathers. Allow the leather to dry
naturally.
