Information Displays

When the electric-only range reaches zero,
the powertrain system switches to hybrid
operation. This means the energy you gain
from plugging in and charging your vehicle
is now gone. Both the gasoline engine and
electric motor power your vehicle and
maximize fuel economy during hybrid
operation. Hybrid operation provides some
electric-only driving as the powertrain system
maintains the high voltage battery charge
level within functional limits.Low Engine Use
The low engine use mode properly lubricates
the engine at sufficient temperature and
activates when you drive your vehicle with
limited engine operation. When in low engine
use mode, your vehicle runs the engine as
necessary. When low engine use mode
begins, a message appears in the information
display. If low engine use mode does not
complete before you switch your vehicle off,
it continues the next time you start your
vehicle and the message reappears. See
Information Messages (page 142).Pure EV mode is not available during low
engine use mode.
Note:Cold temperatures affect the engine
warm up time and the low engine use mode
could operate more frequently.
Note:An oil change is not required but gives
you the option of not running a low engine
use cycle. Resetting the oil life monitoring
system suspends the low engine use mode.

Unique Driving Characteristics

• An open or pinched sensor hose.
• Incorrect engine oil level.
• Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for climactic
conditions.
Note:Some vehicles have a lifetime fuel filter
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.
401
Maintenance

Do not use supplemental engine oil
additives. They could cause engine damage
that the vehicle warranty may not cover.
1. Clean the area surrounding the engine
oil filler cap before you remove it.
2. Remove the engine oil filler cap.
3. Add engine oil that meets our
specifications. See Capacities and
Specifications (page 465).
4. Reinstall the engine oil filler cap. Turn it
clockwise until you feel a strong
resistance.
Note: Do not add oil further than the
maximum mark. Oil levels above the
maximum mark may cause engine damage.
Note:Soak up any spillage with an
absorbent cloth immediately.
