Automatic Level Control
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
0
Put things in the cargo area of your
vehicle. Try to spread the weight evenly.
Never stack heavier things, like suitcases,
inside the vehicle so that some of them
are above the tops of the seats.
Don't leave an unsecured child restraint in
your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Don't leave a seat folded down unless you
need to.
On vehicles equipped with the automatic 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 or when Retained Accessory Power
(RAP) is active, you may hear the compressor operating
when you load or unload your vehicle, and periodically
as the system self-adjusts. This is normal. See
"Retained Accessory Power" under
lgnition Positions
on
page
2-30.
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 away.
