Pontiac 1999 Montana Owner's Manual page 263

CAUTION:
Things you put inside your vehicle can strike and
injure people in a sudden stop or turn, or in
a crash.
D
Put things in the cargo area of your vehicle.
Try to spread the weight evenly.
D
Never stack heavier things, like suitcases,
inside the vehicle so that some of them are
above the tops of the seats.
D
Don't leave an unsecured child restraint in
your vehicle.
D
When you carry something inside the
vehicle, secure it whenever you can.
D
Don't leave a seat folded down unless you
need to.
Electronic Level Control (Option)
On vehicles equipped with the optional electronic level
control, the rear of the vehicle is automatically kept
level as you load or unload your vehicle. However, you
should still not exceed the GVWR or the GAWR.
If the engine is running or the ignition key is in
ACCESSORY, you may hear the compressor operating
when you load or unload your vehicle, and periodically
-
as the system self adjusts. This is normal.
The compressor should operate for brief periods of time.
If the sound continues for an extended period of time,
your vehicle needs service.
Using heavier suspension components to get added
durability might not change your weight ratings. Ask
your dealer to help you load your vehicle the right way.
