Introduction

Engine compartment (with engine stopped)
HVAC air inlet:Check for debris, leaves, etc. that may have
collected on the HVAC air inlet grille or inside
the exterior module as this may cause reduced
system performance.
HVAC fresh air filter
(if equipped):Periodically check the HVAC fresh air filter for
cleanliness.
Exercise great caution when working on vehicle equipped with
an automatic fan clutch. The fan starts in motion only after the
engine coolant reaches a predetermined temperature or the refrigerant
pressure (if equipped with air conditioning) reaches a predetermined
setting. The fan will start at these point with no advance warning.
Never reach near, or permit objects to protrude into, the fan blade
radius while the engine is running as this could result in vehicle
damage, personal injury or death.
Engine starting (parking brake applied)
Safety/Emergency
equipment:Prior to entering the cab, verify that the
vehicle is equipped with spare electrical fuses
(if used), three red reflective triangles, a
properly charged and rated fire extinguisher
and wheel chocks. Walk around the vehicle
and check that all steps and grab handles,
inside and out as well as behind, are tight and
clean. Use extreme caution and a three-point
stance at all times. Check door latches for
positive closing, latching and locking.
Starting the engine:Verify the parking brake is set. Depress the
clutch (if equipped with a manual
transmission) and verify the transmission is in
neutral. Vehicles equipped with an automatic
transmission should be in N (Neutral).
When the WAIT TO START indicator light in
the instrument cluster turns off, turn the key
to START.

HAZARD FLASHER
The hazard flasher control is located
on the steering column, just behind
the steering wheel. The hazard
flashers will operate when the
ignition is off.
Push in the flasher control and all
front and rear direction signals will
flash. Press the flasher control again
to turn them off. Use it when your
vehicle is disabled and is creating a
safety hazard for other motorists.
Note:With extended use, the flasher may run down your battery.
FUSING
If electrical components in the vehicle are not working, a fuse may have
blown. Blown fuses are identified by a broken wire within the fuse.
Check the appropriate fuses before replacing any electrical components.
Note:Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.
