cooling mode. If the engine coolant
supply is depleted, this feature
allows the driver to drive the
vehicle (with limited power) for a
short distance in order to get the
vehicle to a service facility. Take
your vehicle to a service facility as
soon as possible to minimize
engine damage.
The actual distance your vehicle
can be driven depends on vehicle
load, road conditions and outside
temperature.
How fail-safe cooling works
If the engine overheats, the engine
will automatically switch from
eight to alternating four cylinder
operation. Each disabled cylinder
acts as an air pump and cools the
engine.
When this occurs, the engine
coolant temperature gauge will
move into the red area and the
light illuminates.
The
CHECK
ENGINElight will illuminate,
indicating that vehicle service is
required.
The vehicle will still operate, but
will have limited engine power and
no air conditioning capability.
Continued operation will increase
engine temperature and cause the
engine to completely shut down.
The vehicle will coast to a stop.
As the engine temperature cools,
the engine may be re-started. Take
your vehicle to a service facility as

Maintenance and care
171
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.
²Fluid leaks
²The
orCHECK
ENGINElights
illuminate in the instrument
cluster and remain lit
²Strange odors
²Engine runs more than five
seconds after shut-off or engine
misfires, surges, stalls or
backfires
²Loss of oil pressure.
