2015 INFINITI QX60-HYBRID coolant level

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.

the vehicle information display when the parking
brake is set and the vehicle is driven.Low Fuel
This warning illuminates when the fuel level in the
fuel tank is getting low. Refuel as soon as it is
convenient, preferably before the fuel gauge
reaches 0 (Empty) .
There will be a small re-
serve of fuel in the tank when the fuel
gauge needle reaches 0 (Empty) .
Hybrid System Overheated
This warning appears when the temperature of
the Hybrid System is too high. Stop the vehicle in
a safe location as soon as possible. Avoid quick
starting or abrupt acceleration. When the warn-
ing turns off, the vehicle can be driven.

off, have the vehicle checked by an INFINITI
retailer.
Do not drive the vehicle with the warning
on. Doing so could cause a Hybrid System
malfunction.WARNING
If you continue to drive the vehicle while
the warning is displayed, the hybrid sys-
tem may become temporarily inoperative
and the system can not provide power to
the wheels. This can result in reduced or
zero vehicle speed. The reduced speed or
zero speed may be lower than other traf-
fic, which could increase the chance of a
collision. If the vehicle cannot maintain a
safe driving speed, pull to the side of the
road in a safe area. If this occurs, place the
shift lever in the “P” position, ignition in
the READY position with the vehicle
stopped until the display turns off. The
Hybrid system overheat warning and the
SHIFT “P” warning messages will be alter-
nately displayed. For additional informa-
tion, refer to the “Shift to Park” warning in
this section.
