2014 INFINITI Q70 HYBRID engine coolant

Hybrid System-4Hybrid System Overview
The emergency shut-off system is activated
and the high-voltage system automatically
turns off in the following conditions:
.Front and side collisions in which the
air bags are deployed.
. Certain rear collisions.
. Certain INFINITI Direct Response Hy-
brid
®System malfunctions
For the above collisions and the certain
hybrid system malfunctions, the READY to
drive indicator light will turn off. See
“Warning/indicator lights and audible re-
minders” (P.2-10).
The emergency shut-off activates for the
above collisions to minimize risk of an
event that could cause injury or an
accident. If the emergency shut-off system
activates, the hybrid system may not
switched to READY to drive position,
contact an INFINITI retailer. Even if the
ignition switch is switched to READY to
drive position, the system may shut-off
suddenly. Therefore, drive cautiously to the
nearest INFINITI retailer or contact an
INFINITI retailer as soon as possible. To start the INFINITI Direct Response
Hybrid
®System:
1. Depress the brake pedal and place the ignition switch in the ON position when
the transmission is in the P (Park) or N
(Neutral) position (P is recommended).
(For more details, see “Push-button
ignition switch” (P.5-9).)
2. The READY to drive indicator light
flashes, then turns illuminated. (The
hybrid system switched to the READY to
drive mode when the indicator light
illuminates.)
When the READY to drive indicator light
illuminates, the vehicle can be
driven, even if the gasoline engine is not
running.
NOTE:
The gasoline engine starts and stops
automatically. It may stop during low
speed driving, deceleration or when the
vehicle is stopped.
The gasoline engine may automatically
run in the following conditions:
. The level of remaining charge in the
Lithium ion (Li-ion) battery is low. The
engine runs to charge the Li-ion
battery and to provide power to the drive the vehicle.
. The temperature of the engine coolant
is low.
. 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.
STARTING AND SLOW SPEED DRIV-
ING
The vehicle is driven by the electric motor
depending on the available Li-ion battery
charge.
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, depending 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 vehicle is driving.

High temperature warning
light
When the ignition switch is in the ON
position, the high temperature warning
light illuminates and then turns off. This
indicates that the high temperature sensor
in the engine coolant system is opera-
tional.
CAUTION
If the high temperature warning light
illuminates when the ignition switch is in
the ON position, it may indicate the engine
temperature is extremely high.
Stop the vehicle safety as soon as possible.
If the vehicle is overheated, continuing
vehicle operation may seriously damage
the engine. (See “If your vehicle overheats”
(P.6-12) for the immediate action required.)
Hybrid EPS (Electrical Power
Steering) warning light
When the ignition switch is in the ON position, the Hybrid EPS (Electrical Power
Steering) warning light illuminates. After
starting the hybrid system, the Hybrid EPS
warning light turns off. This indicates that
the electrical power steering system is
operational.
If the Hybrid EPS warning light illuminates
while the hybrid system is running, it may
indicates the Hybrid EPS system is not
functioning properly and may need servi-
cing. Have the Hybrid EPS system checked
by an INFINITI retailer.
When the Hybrid EPS warning light illumi-
nates with the hybrid system running, the
power assist to the steering will cease
operation but you will still have control of
the vehicle. At this time, greater steering
efforts are required to operate the steering
wheel, especially in sharp turns and at low
speeds. However, if the steering wheel
operation is still performed, the Hybrid EPS
may stop and the Hybrid EPS warning light
will illuminate. Place the ignition switch in
the OFF position. For a while after it
refrains from the steering wheel control,
the temperature of the Hybrid EPS system
will go down and the power assist level will
return to normal after starting the hybrid
system. The Hybrid EPS warning light will
go off.
Intelligent Cruise Control (ICC)
system warning light (orange; if so
equipped)
This light comes on if there is a malfunc-
tion in the Intelligent Cruise Control (ICC)
system.
If the warning light comes on, park the
vehicle in a safe place. Stop the hybrid
system, restart the hybrid system, resume
driving and set the ICC system again.
If it is not possible to set the system or the
indicator stays on, it may indicate that the
system is malfunctioning. Although the
vehicle is still driveable under normal
conditions, have the vehicle checked at
an INFINITI retailer.
Lane Departure Warning (LDW)
light (orange; if so equipped)
When the ignition switch is pushed to the
ON position, the light will come on in
orange, turn green, and then turn off. This
indicates that the Lane Departure Warning
(LDW) and Lane Departure Prevention (LDP)
systems are operational.
While the LDW and/or LDP system is on,
the light will blink in orange and a warning

Ion control
This unit generates highly concentrated
Plasmacluster®ion into the air blown from
the ventilators and reduces odor absorbed
into the interior trim.
The high-density Plasmacluster
®ions gen-
erated in the air conditioner’s air stream
not only suppress airborne bacteria and
reduce the adherence of odors to the
interior trim, but also have a proven skin
moisture preserving effect.
When the air conditioner is turned on, the
system generates Plasmacluster
®ion auto-
matically. The amount of Plasmacluster
®ion in-
creases according to the amount of air
flow. When the air flow is high, “
”is
displayed on the screen and when the air
flow is low, the indication in the screen
changes to “

OPERATING TIPS
When the engine coolant temperature and
outside air temperature are low, the air
flow from the foot outlets may not operate.
This is not a malfunction. After the coolant
temperature warms up, air will flow nor-
mally from the foot outlets.

after the chime sounds. The hybrid
system will start.
After step 3 is performed, when the
ignition switch is pushed without depres-
sing the brake pedal, the ignition switch
position will change to ACC.
NOTE:
. When the ignition switch is pushed to
the ACC or ON position or the hybrid
system is started by the above proce-
dures, the Intelligent Key battery dis-
charge indicator appears on the dot
matrix liquid crystal display even if the
Intelligent Key is inside the vehicle.
This is not a malfunction. To turn off
the Intelligent Key battery discharge
indicator, touch the ignition switch
with the Intelligent Key again.
. If the Intelligent Key battery discharge
indicator appears, replace the battery
as soon as possible. (See “Intelligent
Key battery replacement” (P.8-26).).
Make sure the area around the vehicle
is clear.
. Check fluid levels such as engine oil,
coolant, brake fluid and window
washer fluid as frequently as possible,
or at least whenever you refuel.
. Check that all windows and lights are
clean.
. Visually inspect tires for their appear-
ance and condition. Also check tires for
proper inflation.
. Lock all doors.
. Position seat and adjust head re-
straints.
. Adjust inside and outside mirrors.
. Fasten seat belts and ask all passen-
gers to do likewise.
. Check the operation of warning lights
when the ignition switch is pushed to
the ON position. (See “Warning/indica-
tor lights and audible reminders” (P.2-
10).) 1. Apply the parking brake.
2. Move the shift lever to P (Park) posi-
tion.
