Loose Fuel Cap
This warning appears when the fuel-filler
cap is not tightened correctly af ter the ve-
hicle has been refueled. For additional in-
formation, refer to “Fuel-filler cap” in the
“Pre-driving checks and adjustments” sec-
tion of this manual.
Tire Pressure Low - Add Air
This warning appears when the low tire
pressure warning light in the meter illumi-
nates and low tire pressure is detected. The
warning appears each time the ignition
switch is placed in the ON position as long
as the low tire pressure warning light re-
mains illuminated. If this warning appears,
stop the vehicle and adjust the tire pres-
sures of all four tires to the recommended
COLD tire pressure shown on the Tire and
Loading Information label. For additional
information, refer to “Low tire pressure
warning light” in this section and “Tire Pres-
sure Monitoring System (TPMS)” in the
“Starting and driving” section of this
manual.
Flat Tire – Visit dealer (if so equipped)
This warning appears when the low tire
pressure warning light in the meter illumi-
nates and one or more flat tires are de-tected while driving. A chime also sounds
for approximately 10 seconds.
Low Oil Pressure Stop Vehicle
This warning appears in the message area
of the vehicle information display if low oil
pressure is detected. This gauge is not de-
signed to indicate low oil level.
The low oil
pressure warning is not designed to indi-
cate a low oil level. Use the dipstick to
check the oil level. For additional informa-
tion, refer to “Engine oil” in the “Do-it-
yourself ” section of this manual.
AWD Error: See Owner’s Manual (if so
equipped)
This warning appears when the all-wheel
drive system is not functioning properly
while the hybrid system is running.
AWD High Temp. Stop vehicle (if so
equipped)
This warning may appear while trying to
free a stuck vehicle due to increased oil
temperature. The driving mode may
change to 2-Wheel Drive (2WD). If this warn-
ing is displayed, stop the vehicle with the
engine idling, as soon as it is safe to do so.
Then if the warning turns off, you can con-
tinue driving. Tire Size Incorrect: See Owner’s Manual
(if so equipped)
This warning may appear if there is a large
difference between the diameters of the
front and rear wheels. Pull off the road in a
safe area, with the engine idling. Check that
all the tire sizes are the same, that the tire
pressure is correct and that the tires are
not excessively worn.
Battery Voltage Low Charge Battery
This warning appears when the battery is
low and needs to be charged.
Shipping Mode On Push Storage Fuse
This warning may appear if the extended
storage switch is not pushed in. When this
warning appears, push in the extended
storage switch to turn off the warning. For
additional information, refer to “Extended
storage switch” in this section.
Power will turn off to save the battery
This warning appears in the message area
of the vehicle information display af ter a
period of time if the shif t lever has not
moved from the P (Park) position.

CHECKING INVERTER COOLANT
LEVEL
Check the coolant levelin the reservoir
when the engine and inverter are cold.
The coolant level should be between the
MIN level
B, add coolant to the MAX level
A.
If the inverter cooling system frequently
requires coolant, have it checked. It is
recommended that you visit a NISSAN
dealer for this service.
CHANGING INVERTER COOLANT
It is recommended that major cooling sys-
tem repairs be done by a NISSAN dealer.
The service procedure can be found in the
NISSAN Service Manual.
Improper servicing can result in inverter
overheating.
WARNING
∙ To avoid the danger of being scalded, never change the coolant when the
inverter is hot.
∙ Never remove the cap when the in- verter is hot. Serious burns could be
caused by high pressure fluid escap-
ing from the inverter coolant
reservoir.
∙ Avoid direct skin contact with used coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
∙ Keep coolant out of the reach of chil- dren and pets.
Engine coolant must be disposed of prop-
erly. Check your local regulations.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and apply the parking brake.
2. Start the hybrid system and let it idle until it reaches operating temperature.
3. Turn off the hybrid system. Wait more
than 10 minutes for the oil to drain
back into the oil pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way.

5. Remove the dipstick again and checkthe oil level. It should be between the H
(High) and L (Low) marks
B. This is the
normal operating oil level range. If the
oil level is below the L (Low) mark
A,
remove the oil filler cap and pour rec-
ommended oil through the opening.
Do not overfill
C.
6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the sever-
ity of operating conditions.
CAUTION
Oil level should be checked regularly.
Operating the engine with an insuffi-
cient amount of oil can damage the en-
gine, and such damage is not covered
by warranty.
CHANGING ENGINE OIL
1. Park the vehicle on a level surface and apply the parking brake.

2. Start the hybrid system and let it idleuntil it reaches operating temperature,
then turn it off.
3. Remove the oil filler cap
Bby turning it
counterclockwise.
4. Place a large drain pan under the drain plug
A.
5. Remove the drain plug
Awith a
wrench by turning it counterclockwise
and completely drain the oil.
If the oil filter is to be changed, remove
and replace it at this time. For addi-
tional information, refer to “Changing
engine oil filter” in this section.
∙ Waste oil must be disposed of prop-
erly.
∙ Check your local regulations.
WARNING
∙ Prolonged and repeated contact with
used engine oil may cause skin
cancer.
∙ Try to avoid direct skin contact with used oil. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
∙ Keep used engine oil out of reach of children.
CAUTION
Be careful not to burn yourself. The en-
gine oil may be hot.
6. Clean and reinstall the drain plug and a new washer. Securely tighten the drain
plug with a wrench. Do not use exces-
sive force.
Drain plug tightening torque: 25 f t-lb (34 N·m) 7. Refill engine with recommended oil
through the oil filler opening, then install
the oil filler cap securely.
For additional information, refer to
“Recommended fluids/lubricants and
capacities” in the “Technical and con-
sumer information” section of this
manual for drain and refill capacity.
The drain and refill capacity depends
on the oil temperature and drain time.
Use these specifications for reference
only. Always use the dipstick to deter-
mine when the proper amount of oil is
in the engine.
8. Start the hybrid system. Check for leak- age around the drain plug and oil filter.
Correct as required.
9. Turn the hybrid system off and wait more than 10 minutes. Check the oil
level with the dipstick. Add engine oil if
necessary.

CHANGING ENGINE OIL FILTER
1. Park the vehicle on a level surface andapply the parking brake.
2. Turn the hybrid system off.
3. Place a large drain pan under the oil filter
B.
4. Remove oil filter
Bwith an oil filter
wrench by turning it counterclockwise.
Then remove the oil filter by turning it
by hand.
CAUTION
Be careful not to burn yourself. The en-
gine oil may be hot.
5. Wipe the engine oil filter sealing surface with a clean rag.
CAUTION
∙ Be sure to remove any old gasketmaterial remaining on the sealing
surface of the engine. Failure to do
so could lead to an oil leak and en-
gine damage.
∙ The dipstick must be inserted in place to prevent oil spillage from
the dipstick hole when filling the
engine with oil.
6. Coat the gasket on the new filter with clean engine oil.
7. Screw on the oil filter until a slight resis- tance is felt, then tighten an additional
2/3 turn. 8. Start the hybrid system and check for
leakage around the oil filter. Correct as
required.
9. Turn the hybrid system off and wait more than 10 minutes. Check the oil
level. Add engine oil if necessary.
