2017 INFINITI QX60 HYBRID engine 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.

LOCATIONS
0-8Illustrated table of contents

High beam indicator light(blue)
This blue light comes on when the headlight high
beams are on and goes out when the low beams
are selected.
The high beam indicator light also comes on
when the passing signal is activated.
Low temperature indicatorlight (blue)
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. It is recom-
mended that you have the system checked, and if
necessary repaired. It is recommended that you
visit an INFINITI retailer for this service.
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 sec-
onds 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 infor-
mation, refer to “Readiness for
inspection/maintenance (I/M) test” in the “Tech-
nical and consumer information” section of this
manual. Operation
The MIL will come on in one of two ways:
● MIL on steady — An emission control system
malfunction has been detected. Check the
fuel-filler cap if the LOOSE FUEL CAP
warning appears in the vehicle information
display. If the fuel-filler cap is loose or miss-
ing, tighten or install the cap and continue to
drive the vehicle. The
light should turn
off after a few driving trips. If the
light
does not turn off after a few driving trips,
have the vehicle inspected. It is recom-
mended that you visit an INFINITI retailer for
this service. You do not need to have your
vehicle towed to the retailer.
● MIL blinking — An engine misfire has been
detected which may damage the emission
control system. To reduce or avoid emission
control system damage:
– do not drive at speeds above 45 mph (72 km/h).
– avoid hard acceleration or deceleration.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo being hauled or towed.

High Coolant Temp: See Owner’s Manual
This warning appears when the temperature of
the engine coolant 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.
If the warning appears again soon after it turns
off, have the vehicle checked. It is recommended
that you visit an INFINITI retailer for this service.Your vehicle has two types of security systems:● Vehicle security system
● INFINITI Vehicle Immobilizer System
VEHICLE SECURITY SYSTEM
The vehicle security system provides visual and
audible alarm signals if someone opens the
doors, liftgate or hood when the system is armed.
It is not, however, a motion detection type system
that activates when a vehicle is moved or when a
vibration occurs.
The system helps deter vehicle theft but cannot
prevent it, nor can it prevent the theft of interior or
exterior vehicle components in all situations. Al- ways secure your vehicle even if parking for a
brief period. Never leave your Intelligent Key in
the vehicle, and always lock the vehicle when
unattended. Be aware of your surroundings, and
park in secure, well-lit areas whenever possible.
Many devices offering additional protection, such
as component locks, identification markers, and
tracking systems, are available at auto supply
stores and specialty shops. An INFINITI retailer
may also offer such equipment. Check with your
insurance company to see if you may be eligible
for discounts for various theft protection features.
How to arm the vehicle security
system
1. Close all windows and the moonroof.
The
system can be armed even if the win-
dows and moonroof are open.
2. Remove the Intelligent Key from the vehicle.
3. Close all doors, hood and liftgate. Lock all doors. The doors can be locked with the
Intelligent Key, door handle request switch
or power door lock switch.
Key fob operation:
4. Confirm that the
indicator light comes
on. The
indicator stays illuminated for
a period of time indicating that the system is
in the pre-armed phase.

Do not attach stickers (including transparent ma-
terial) , install accessories or apply additional
paint near the sonar sensors.
Do not strike or damage the area around the
sonar sensors. It is recommended that you visit
an INFINITI retailer if the area around the sonar
sensors is damaged due to a collision.FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply de-
icer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the key
hole, or use the INFINITI Intelligent Key.
ANTIFREEZE
In the winter when it is anticipated that the tem-
perature will drop below 32°F (0°C) , check the
antifreeze to assure proper winter protection. For
additional information, refer to “Engine cooling
system” in the “Do-it-yourself” section of this
manual.
BATTERY
If the battery is not fully charged during extremely
cold weather conditions, the battery fluid may
freeze and damage the battery. To maintain maxi-
mum efficiency, the battery should be checked
regularly. For additional information, refer to “Bat-
tery” in the “Do-it-yourself” section of this manual.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without anti-
freeze, drain the cooling system, including the
engine block. Refill before operating the vehicle.
For additional information, refer to “Changing
engine coolant” in the “Do-it-yourself” section of
this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your ve-
hicle on snowy or icy roads, INFINITI recom-
mends the use of MUD & SNOW or ALL
SEASON TIRES on all four wheels. It is
recommended that you visit an INFINITI re-
tailer for the tire type, size, speed rating and
availability information.
2. For additional traction on icy roads, studded tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow tires. 3. Tire chains may be used. For additional in- formation, refer to “Tire chains” in the “Do-it-
yourself” section of this manual.
COLD WEATHER DRIVING

4. Plug the extension cord into a Ground FaultInterrupt (GFI) protected, grounded 110-
volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least2-4hours, depending on outside
temperatures, to properly warm the engine
coolant. Use an appropriate timer to turn the
engine block heater on.
6. Before starting the hybrid system, unplug and properly store the cord to keep it away
from moving parts.
This system uses microphones
1located inside
the vehicle to detect engine booming noise. The
system then automatically generates a noise can-
celing sound through the speakers and woofer (if
so equipped) to reduce engine booming noise.
NOTE:
To operate the active noise cancellation
system properly:
● Do not cover the speakers or woofer (if so
equipped) .
● Do not cover the microphones.
