²Use only unleaded fuel.
²Avoid running out of fuel.
²Do not turn off the ignition
while the vehicle is in motion.
²Have regular maintenance
checks performed according to
the intervals in theService
Guide.
When servicing your vehicle, never
use a metal exhaust collector. A
metal collector may melt or deform
plastic parts.
Do not park, idle, or drive
your vehicle in dry grass
or other dry ground cover. The
emission system heats up the
engine compartment and exhaust
system, which can start a fire.
If you smell exhaust fumes
inside your vehicle, have
your dealer inspect your vehicle
immediately. Do not drive if you
smell exhaust fumes.
On vehicles without
original equipment floor
covering or insulation, do not let
passengers ride in your truck in
a manner that allows contact
between skin and the metal floor.
If you notice one or more of the
following, the emissions system
may not be working properly. Have
your vehicle serviced as soon as
possible.
