• An open or pinched sensor hose.
• Incorrect engine oil level.
• Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for climactic
conditions.

that is integrated with the fuel tank. Regular
maintenance or replacement is not needed.
Note:If these checks do not help you correct
the concern, have your vehicle checked as
soon as possible.
Noise Emissions Warranty, Prohibited
Tampering Acts and Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb (4,536 kg)
Gross Vehicle Weight Rating (GVWR). The
preceding statements concerning prohibited
tampering acts and maintenance, and the
noise warranty found in the Warranty Guide,
are applicable to complete chassis cabs over
10,000 lb (4,536 kg) GVWR.
CATALYTIC CONVERTER
WARNING: Do not park, idle or drive
your vehicle on dry grass or other dry
ground cover. The emission system heats
up the engine compartment and exhaust
system, creating the risk of fire.
WARNING: The normal operating
temperature of the exhaust system is very
high. Never work around or attempt to
repair any part of the exhaust system until
it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short period
of engine operation and stays hot after the
engine is switched off.
WARNING: Exhaust leaks may result
in entry of harmful and potentially lethal
fumes into the passenger compartment. If
you smell exhaust fumes inside your
vehicle, have your vehicle inspected
immediately. Do not drive if you smell
exhaust fumes.Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable exhaust
emission standards.
To make sure that the catalytic converter and
other emission control components continue
to work properly:
• Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables. See Jump
Starting the Vehicle (page 366).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note:Resulting component damage may
not be covered by the vehicle Warranty.

ENGINE OIL CHECK
1. Make sure that your vehicle is on level
ground.
2. Check the oil before starting the engine
or switch the engine off and wait 10
minutes for the oil to drain into the oil
pan.
3. Remove the dipstick and wipe it with a
clean, lint-free cloth.
4. Reinstall the dipstick and make sure it is
fully seated. Remove it again to check
the oil level.
5. If the oil level is between the maximum
and minimum marks, the oil level is
acceptable. Do not add oil.6. If the oil level is at the minimum mark,
immediately add oil.
7. Reinstall the dipstick. Make sure it is fully
seated.
Note:The oil consumption of new engines
reaches its normal level after approximately
3,000 mi (5,000 km).
Adding Engine Oil
WARNING: Do not remove the filler
cap when the engine is running.
WARNING: Do not add engine oil
when the engine is hot. Failure to follow
this instruction could result in personal
injury.

Maintenance

Body
• Wash your vehicle thoroughly to remove
dirt, grease, oil, tar or mud from exterior
surfaces, rear-wheel housing and the
underside of front fenders.
• Periodically wash your vehicle if it is
stored in exposed locations.
• Touch-up exposed or primed metal to
prevent rust.
• Cover chrome and stainless steel parts
with a thick coat of auto wax to prevent
discoloration. Re-wax as necessary when
you wash your vehicle.
• Lubricate all hood, door and luggage
compartment hinges and latches with a
light grade oil.
• Cover interior trim to prevent fading.
• Keep all rubber parts free from oil and
solvents.
Engine
• Change the engine oil and filter prior to
storage because used engine oil contains
contaminates which may cause engine
damage.
• Start the engine every 15 days for a
minimum of 15 minutes. Run at fast idle
with the climate controls set to defrost
until the engine reaches normal
operating temperature.
• With your foot on the brake, shift through
all the gears while the engine is running.
• We recommend that you change the
engine oil before you use your vehicle
again.
Fuel system
• Fill the fuel tank with high-quality fuel
until the first automatic shutoff of the fuel
pump nozzle.
Cooling system
• Protect against freezing temperatures.
• When removing your vehicle from
storage, check coolant fluid level.
Confirm that there are no cooling system
leaks and that fluid is at the
recommended level.
Disconnecting Your 12 Volt Battery
• Check and recharge as necessary. Keep
connections clean.
• If storing your vehicle for more than 30
days without recharging the battery, we
recommend that you disconnect the
battery cables to maintain battery charge
for quick starting.
Note:It is necessary to reset memory
features if you disconnect the battery cables.
