Notice Overloading the vehicle may cause
:
damage. Repairs would not be covered by the
vehicle warranty. Do not overload the vehicle.
If you put things inside your vehicle, like
suitcases, tools, packages, or anything else, they
will go as fast as the vehicle goes. If you have
to stop or turn quickly, or if there is a crash, they
will keep going.
WARNING:
{
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
•
Put things in the trunk of your vehicle. In
a trunk, put them as far forward as you
can. 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.
•
Do not leave an unsecured child restraint
in your vehicle.
•
When you carry something inside the
vehicle, secure it whenever you can.
Automatic Level Control
This feature keeps the rear of your vehicle level
as the load changes. It is automatic, you do
not need to adjust anything.
This type of level control is fully automatic and will
provide a better leveled riding position as well as
better handling under a variety of passenger and
loading conditions. An air compressor connected to
the rear shocks will raise or lower the rear of the
vehicle to maintain proper vehicle height. The
system is activated when the ignition key is turned
to ON/RUN and will automatically adjust vehicle
height thereafter. The system may exhaust
(lower vehicle height) for up to ten minutes after
the ignition key has been turned to LOCK/OFF.
You may hear the air compressor operating when
the height is being adjusted.
