2015 INFINITI QX60-HYBRID coolant

The gasoline engine may automatically run in the
following conditions:● The level of remaining charge in the Li-ion
battery is low. The engine runs to charge the
Li-ion battery and to provide power to drive
the vehicle.
● The temperature of the engine coolant is
low.
● When the A/C is used.
● When opening the door.
● When the engine hood is opened.
● When applying the brakes.
● Based on driving conditions.
● The shift lever is shifted to the P (Park)
position, the driver’s seat belt is released
and the driver’s side door is then opened.
The hybrid system operates as follows based on
driving conditions and the Li-ion battery charge.
The engine is hard to stop during these driving
conditions: ● Outside temperature is high/low and A/C is
on.
● When repeatedly starting and stopping the
engine.STARTING AND SLOW SPEED
DRIVING
In some cases, the vehicle can be driven by
electric motor during extremely slow speed
creep, but the engine starts when accelerating or
releasing the brakes.
MEDIUM OR HIGH SPEED DRIVING
The system automatically controls the gasoline
engine and electric motor in order to obtain the
optimum fuel mileage and performance, depend-
ing on the driving situation and available Li-ion
battery charge.
When the remaining battery level is low, the Li-ion
battery is charged by the electric motor that is
driven to generate electric power while the ve-
hicle is driving.
RAPID ACCELERATION
The vehicle is accelerated using both the gaso-
line engine and the electric motor depending on
the available Li-ion battery charge.
DECELERATION AND BRAKING
The Li-ion battery is charged by the electric mo-
tor that changes the energy of the rotating
wheels into electric power. For additional infor-
mation, refer to “Regenerative brake” in this sec-
tion.
STOPPING
The gasoline engine may stop running to save
fuel depending on the available Li-ion battery
charge.

TACHOMETER
The tachometer indicates engine speed in revo-
lutions per minute (RPM) . Do not rev the engine
into the red zone
1.
CAUTION
When engine speed approaches the red
zone, shift to a higher gear or reduce en-
gine speed. Operating the engine in the
red zone may cause serious engine
damage.
ENGINE COOLANT TEMPERATURE
GAUGE
The gauge indicates the engine coolant tempera-
ture. The engine coolant temperature is within the
normal range
1when the gauge needle points
within the zone shown in the illustration.
The engine coolant temperature varies with the
outside air temperature and driving conditions.
CAUTION
If the gauge indicates coolant tempera-
ture near the hot (H) end of the normal
range, reduce vehicle speed to decrease
temperature. If the gauge is over the nor-
mal range, stop the vehicle as soon as
safely possible. If the engine is over-
heated, continued operation of the vehicle
may seriously damage the engine. For ad-
ditional information, refer to “If your ve-
hicle overheats” in the “In case of emer-
gency” section for immediate action
required.

Low temperature indicatorlight
The low temperature indicator light illuminates
when the engine coolant temperature is low.
When the ignition switch is placed in the ON
position, the low temperature indicator light illu-
minates and then turns off after the engine cool-
ant has warmed up. If the low temperature indicator light stays illumi-
nated after the engine has sufficiently warmed
up, it may indicate the low temperature sensor in
the engine coolant system is not functioning
properly and may need servicing. Have the sys-
tem checked, and if necessary repaired, by a
INFINITI retailer promptly.
Malfunction Indicator Light (MIL)
If this indicator light comes on steady or blinks
while the engine is running, it may indicate a
potential emission control malfunction.
The MIL may also come on steady if the fuel-filler
cap is loose or missing, or if the vehicle runs out
of fuel. Check to make sure the fuel-filler cap is
installed and closed tightly, and that the vehicle
has at least 3 gal (11.4 L) of fuel in the fuel tank.
After a few driving trips, the
light should
turn off if no other potential emission control
system malfunction exists.
If this indicator light comes on steady for 20 seconds
and then blinks for 10 seconds when the engine is
not running, it indicates that the vehicle is not ready
for an emission control system
inspection/maintenance test. For additional informa-
tion, refer to “Readiness for inspection/maintenance
(I/M) test” in the “Technical and consumer informa-
tion” section of this manual.
