WARNING
Modifying your vehicle can make it un-
safe. Some modifications can affect
your vehicle's electrical system, stabili-
ty, or other important functions. Before
modifying your vehicle, check with
your dealer to make sure it can be
done safely. Improper modifications
can cause death or personal injury.
CAUTION
The installation of electronic devices to
the On Board Diagnostics (OBD) con-
nector, the vehicle Controller Area Net-
work (CAN), or their associated wiring
is not permitted. Doing so can ad-
versely affect vehicle performance
and/or cause fault codes to be record-
ed. The OBD connector is provided for
temporary connection of service tools
and for diagnostic purposes only.
Your dealer’s service center is the best
place to have your vehicle repaired. You
can find dealers all over the country with
the equipment and trained personnel to get
you back on the road quickly—and keep
you there.
Your vehicle is a complex machine.
Anyone attempting repairs on it needs
good mechanical training and the proper
tools. If you are sure you have these
requirements, then you can probably
perform some repairs yourself. However,
all warranty repairs must be performed by
an authorized service facility. If you aren’t
an experienced mechanic, or don’t have
the right equipment, please leave all
repairs to an authorized service facility.
They are the ones equipped to do the job
safely and correctly.
Maintenance Manuals
If you do decide to do any complex repair
work, you’ll need the maintenance
manuals. Order them from your authorized
dealer. Please provide your Chassis Serial
Number when you order, to be sure you
get the correct manuals for your vehicle.
Allow about four weeks for delivery. There
will be a charge for these manuals.
Final Chassis Bill of Material
A complete, non-illustrated computer
printout listing of the parts used to custom-
build your vehicle is available through the
dealer from whom you purchased your
vehicle.
