The vehicle will automatically enter into the Fuel and Oil
Refresh Mode to minimize potential for stale fuel, and to
ensure lubrication of internal engine components. When
operating in this mode, the gas engine will run to provide
vehicle propulsion (electric only operation is inhibited). A
message will be displayed in the instrument cluster when-
ever Fuel and Oil Refresh Mode is active.
The vehicle will automatically exit the Fuel and Oil Refresh
Mode when conditions have been satisfied. If the vehicle
enters Fuel and Oil Refresh Mode, due to fuel which has
been in the fuel tank for a long period of time (becoming
stale fuel), the engine will run whenever the vehicle is
operational (no electric only operation) until the low fuel
level warning is activated. It is also possible to exit the Fuel
and Oil Refresh Mode sooner by adding a minimum of 4
gallons of new fuel to the vehicle’s fuel tank.
NOTE:If the vehicle enters Fuel and Oil Refresh Mode to
maintain engine lubrication, adding fuel will not exit the
mode sooner. If the vehicle enters Fuel and Oil Refresh Mode to maintain
engine lubrication properties, the engine may run for a
period of up to 20 minutes when fully warm whenever the
vehicle is operational (no electric only operation). If the
vehicle is shut down before conditions to exit the refresh
mode have been satisfied, the engine may run for addi-
tional time on subsequent trips.
NOTE:
Frequent short trips at low ambient temperature
conditions are more likely to trigger the lubrication based
mode.

Checking Oil Level
To assure proper engine lubrication, the engine oil must be
maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time to
check the engine oil level is about five minutes after a fully
warmed engine is shut OFF.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain the
oil level between the MIN and MAX markings on the
dipstick. Adding one quart or one liter of oil when the
reading is at the MIN mark will result in a MAX reading on
these engines.
CAUTION!
•Overfilling or underfilling will cause oil aeration, or
loss of oil pressure. This could damage your engine.
• Never use Non-Detergent Oil or Straight Mineral Oil
in the engine or damage may result.
Adding Washer Fluid
The fluid reservoir is located in the front of the engine
compartment. Be sure to check the fluid level in the
reservoir at regular intervals. Fill the reservoir with wind-
shield washer solvent (not radiator antifreeze) and operate
the system for a few seconds to flush out the residual
washer fluid.
When refilling the washer fluid reservoir, take some
washer fluid, apply it to a cloth or towel, and wipe clean
the wiper blades; this will help blade performance.

WARNING!
•Use only refrigerants and compressor lubricants ap-
proved by the manufacturer for your air conditioning
system. Some unapproved refrigerants are flam-
mable and can explode, injuring you. Other unap-
proved refrigerants or lubricants can cause the sys-
tem to fail, requiring costly repairs. Refer to
Warranty Information Book, located in your owner ’s
information kit, for further warranty information.
• The air conditioning system contains refrigerant un-
der high pressure. To avoid risk of personal injury or
damage to the system, adding refrigerant or any
repair requiring lines to be disconnected should be
done by an experienced technician.
CAUTION!
Do not use chemical flushes in your air conditioning
system as the chemicals can damage your air condition-
ing components. Such damage is not covered by the
New Vehicle Limited Warranty.
Refrigerant Recovery And Recycling — R–1234yf
R–1234yf Air Conditioning Refrigerant is a hydrofluo-
roolefin (HFO) that is endorsed by the Environmental
Protection Agency and is an ozone-friendly substance with
a low global-warming potential. The manufacturer recom-
mends that air conditioning service be performed by
authorized dealer using recovery and recycling equipment.
NOTE: Use only manufacturer approved A/C system
POE compressor oil, and refrigerants.
Air Conditioning Filter Replacement (Cabin Air
Filter)
WARNING!
Do not remove the cabin air filter while the vehicle is
running, or while the ignition is in the ACC or ON/
RUN mode. With the cabin air filter removed and the
blower operating, the blower can contact hands and
may propel dirt and debris into your eyes, resulting in
personal injury.
