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. For more about
this option see "Electronic Level Control" in the Index.
Using heavier suspension components to get added
durability might not change your weight ratings. Ask
your retailer to help you load your vehicle the right way.
NOTICE:
Your warranty does not cover parts or
components that fail because of overloading.
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'll keep going.
