charge is low.
Please park vehicle as soon as possible. It is
recommended that you visit an INFINITI
retailer.
Transmission Shift Position
indicator
This indicator shows the transmission shift
position.
Tire Pressure Low - Add Air
This warning appears when the low tire pres-
sure warning light in the meter illuminates
and low tire pressure is detected. The warn-
ing appears each time the ignition switch is
placed in the ON position as long as the low
tire pressure warning light remains illumi-
nated. If this warning appears, stop the ve-
hicle and adjust the tire pressures of all four
tires to the recommended COLD tire pres-
sure shown on the Tire and Loading Informa-
tion label. For additional information, see
“Low tire pressure warning light” (P. 2-13)
and “Tire Pressure Monitoring System
(TPMS)” (P. 5-5).
When parked apply parking
brake
This message appears when a malfunction
occurs in the electric shift control system be-
low 6 mph (10 km/h).
Have the system checked. It is recommended
that you visit an INFINITI retailer for this
service.
AWD Error: See Owner’s
Manual
This warning appears when the all-wheel
drive system is not functioning properly while
the engine is running.
AWD High Temp. Stop vehicle
This warning may appear while trying to free
a stuck vehicle due to increased oil tempera-
ture. The driving mode may change to
2-Wheel Drive (2WD). If this warning is dis-
played, stop the vehicle with the engine idling,
as soon as it is safe to do so. Then if the
warning turns off, you can continue driving.
AWD Tire Size Incorrect: See
Owner’s Manual
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.
CVT (AT) Malfunction Service now
This warning appears when there is a prob-
lem with the CVT system. If this warning
comes on, have the system checked. It is rec-
ommended that you visit an INFINITI retailer
for this service.
CVT (AT) hot Power reduced
This transmission has a high fluid tempera-
ture protection mode. If the fluid temperature
becomes too high (for example, climbing
steep grades in high temperatures with heavy
loads, such as when towing a trailer), engine
power and, under some conditions, vehicle
speed will be decreased automatically to re-
duce the chance of transmission damage.
Vehicle speed can be controlled with the ac-
celerator pedal, but the engine and vehicle
speed may be reduced.
2-24Instruments and controls

• Recirculating the cool air in the cabinwhen the A/C is on reduces cooling
load.
4. Drive at Economical Speeds and
Distances
• Observing the speed limit and not ex- ceeding 60 mph (97 km/h) (where le-
gally allowed) can improve fuel effi-
ciency due to reduced aerodynamic
drag.
• Maintaining a safe following distance behind other vehicles reduces unneces-
sary braking.
• Safely monitoring traffic to anticipate changes in speed permits reduced brak-
ing and smooth acceleration changes.
• Select a gear range suitable to road conditions.
5. Use Cruise Control
• Using cruise control during highway driving helps maintain a steady speed.
• Cruise control is particularly effective in providing fuel savings when driving on
flat terrains.
6. Plan for the Shortest Route
• Utilize a map or navigation system to determine the best route to save time. 7.
Avoid Idling
• Shutting off your engine when safe for stops exceeding 30–60 seconds saves
fuel and reduces emissions.
8. Buy an Automated Pass for Toll Roads
• Automated passes permit drivers to use special lanes to maintain cruising speed
through the toll and avoid stopping and
starting.
9. Winter Warm Up
• Limit idling time to minimize impact to fuel economy.
• Vehicles typically need no more than 30 seconds of idling at start-up to effec-
tively circulate the engine oil before
driving.
• Your vehicle will reach its ideal operat- ing temperature more quickly while driv-
ing versus idling.
10. Keeping your Vehicle Cool
• Park your vehicle in a covered parking area or in the shade whenever possible.
• When entering a hot vehicle, opening the windows will help to reduce the in-
side temperature faster, resulting in re-
duced demand on your A/C system. • Keep your engine tuned up.
• Follow the recommended scheduled
maintenance.
• Keep the tires inflated to the correct pres- sure. Low tire pressure increases tire wear
and lowers fuel economy.
• Keep all the wheels in correct alignment. Improper alignment increases tire wear and
lowers fuel economy.
• Use the recommended viscosity engine oil. For additional information, see “Engine oil
and oil filter recommendations” (P. 10-6).

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface andapply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. 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 check the
oil level. It should be between the H (High)
and L (Low) marksOB. This is the normal
operating oil level range. If the oil level is
below the L (Low) mark
OA, remove the oil
filler cap and pour recommended oil
through the opening. Do not fill oil level
above H (High) mark
OC.
6. Recheck the oil level with the dipstick.
It is normal to add some oil between oil main-
tenance intervals or during the break-in pe-
riod, depending on the severity of operating
conditions.
CAUTION
Oil level should be checked regularly. Oper-
ating the engine with an insufficient
amount of oil can damage the engine, and
such damage is not covered by warranty.
CHANGING ENGINE OIL AND OIL
FILTER
