2018 INFINITI Q50 HYBRID automatic transmission

Hybrid System-4Hybrid System Overview
delivered to an INFINITI retailer to
have the Li-ion battery pack and high
voltage parts such as the inverter,
including the wiring harness, re-
moved prior to painting. Li-ion bat-
tery packs exposed to heat in the
paint booth will experience capacity
loss. Damaged Li-ion battery packs
may also pose safety risks to un-
trained mechanics and repair person-
nel.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 “Warn-
ing lights, indicator lights and audible re-
minders” (P.2-9).
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 switch to READY to
drive position. If this occurs, it is recom-
mended that you contact an INFINITI re-
tailer. Even if the ignition switch is switched
to READY to drive position, the system may
shut-off suddenly. Therefore, drive cau-
tiously 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.5-11).)
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 auto-
matically. 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.

RESPONSE HYBRID®SYSTEM

HYBRID VEHICLE CHARACTER-
ISTICS
WARNING
.When you leave your vehicle, be sure
to place the ignition switch in the
OFF position.
. Be sure to put the transmission in the
P (Park) position because the vehicle
can move when the READY to drive
indicator light is on even if the gaso-
line engine is not running. When the
READY to drive indicator light is on,
do not leave your vehicle in a shift
position other than the P (Park)
position. The vehicle will creep and
start abruptly if the accelerator pedal
is depressed by mistake. This may
cause serious injury or death.
CAUTION
If the vehicle is parked for a long period
of time, the battery discharges gradu-
ally. To avoid this occurrence, drive the
vehicle for approximately 30 minutes at
least once every two to three months.
Otherwise, the Lithium ion (Li-ion) bat- tery may be damaged. If the Li-ion
battery is completely discharged and
the hybrid system cannot be activated,
it is recommended that you contact an
INFINITI retailer.
High voltage parts and harnesses on the
hybrid vehicles emit approximately the same
amount of electromagnetic waves as the
conventional gasoline-powered vehicles or
home electronic appliances despite of their
electromagnetic shieldings. Unwanted noise
may occur in the reception of a mobile two-
way radio.
Charging the Li-ion battery while driving is
important. The vehicle cannot run if the Li-
ion battery is discharged. When in the N
(Neutral), D (Drive) or R (Reverse) position,
and while the accelerator pedal or the brake
pedal is not depressed, the Li-ion battery
does not recharge. Leaving the transmission
in the N (Neutral), D (Drive) or R (Reverse)
position, and while the accelerator pedal or
the brake pedal is not depressed for an
extended period of time (for example, when
the shift lever is in the D (Drive) position and
the vehicle is stopped only by the parking
brake), may discharge the Li-ion battery and
the hybrid system may automatically be
turned off.

An air ventis located on the right and left
sides between the rear seat and rear door to
cool the Li-ion battery and DC/DC conver-
ter. If the vent is covered, the Li-ion battery
or DC/DC converter will overheat resulting
in reduced output performance of the hybrid
system. See “Lithium-ion (Li-ion) battery
and DC/DC converter air vent” (P.7-5).

PROGRAMMING HomeLink®FOR
CANADIAN CUSTOMERS AND
GATE OPENERS
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission –
which may not be long enough for
HomeLink
®to pick up the signal during
programming. Similar to this Canadian law,
some U.S. gate operators are designed to
“time-out” in the same manner.
If you live in Canada or you are having
difficulties programming a gate operator or
garage door opener by using the “Program-
ming HomeLink
®” procedures, replace “Pro-
gramming HomeLink®” Step 2 with the
following:
NOTE:
When programming a garage door opener,
etc., unplug the device during the “cycling”
process to prevent possible damage to the
garage door opener components.
Step 2: Using both hands, simultaneously
press and hold the desired HomeLink
®
button and the hand-held transmitter but-
ton. During programming, your hand-held
transmitter may automatically stop trans-
mitting. Continue to press and hold the
desired HomeLink
®button while you press
and re-press (“cycle”) your hand-held trans- mitter every two seconds until the frequency
signal has been learned. The HomeLink
®
indicator light will flash slowly and then
rapidly after several seconds upon success-
ful programming.
DO NOTrelease until the
HomeLink
®indicator light flashes slowly and
then rapidly. When the indicator light flashes
rapidly, both buttons may be released. The
rapid flashing indicates successful program-
ming.
Proceed with “Programming HomeLink
®”
step 3 to complete.
Remember to plug the device back in when
programming is completed.
OPERATING THE HomeLink®
UNIVERSAL TRANSCEIVER
The HomeLink®Universal Transceiver, after
it is programmed, can be used to activate the
programmed device. To operate, simply
press and release the appropriate pro-
grammed HomeLink
®Universal Transceiver
button. The amber indicator light will illumi-
nate while the signal is being transmitted.
For convenience, the hand-held transmitter
of the device may also be used at any time.

REMOTE START
Vehicles started with the remote engine
start function require the ignition switch to
be placed in the ON position before the shift
lever can be moved from the P (Park)
position. To place the ignition switch in the
ON position, perform the following steps:
1. Make sure that the Intelligent Key is on you.
2. Depress the brake pedal.
3. Push the ignition switch once to the ON position.
For additional information about the remote
engine start function, see “Remote engine
start” (P.3-19).
AUTOMATIC TRANSMISSION
The automatic transmission in your vehicle is
electronically controlled by a transmission
control module to produce maximum effi-
ciency and smooth operation.
Shown on the following pages are the
recommended operating procedures for this
transmission. Follow these procedures for
maximum vehicle performance and driving
enjoyment.
Starting the vehicle
After starting the INFINITI Direct Response
Hybrid®System, fully depress the foot brake
pedal and push the shift lever button before
shifting the shift lever to the R (Reverse), N
(Neutral), D (Drive) or Manual shift mode
position. Be sure the vehicle is fully stopped
before attempting to shift the shift lever.
This Automatic Transmission (AT) model is
designed so that the foot brake pedal must
be depressed before shifting from P (Park)
to any drive position while the ignition
switch is in the ON position.
The shift lever cannot be moved out of the P
(Park) position and into any of the other
gear positions if the ignition switch is
pushed to the LOCK, OFF or ACC position.
1. Keep the foot brake pedal depressed and push the shift lever button to shift into a driving gear.
2. Release the parking brake and foot brake, then gradually start the vehicle in
motion.
WARNING
.Do not depress the accelerator pedal
while shifting from P (Park) or N
(Neutral) to R (Reverse), D (Drive) or
manual shift mode. Always depress
the brake pedal until shifting is
completed. Failure to do so could
cause you to lose control and have
an accident.
. Cold engine idle speed is high, so use
caution when shifting into a forward
or reverse gear before the engine has
warmed up.
. Never shift to either P (Park) or R
(Reverse) position while the vehicle is
moving forward and P (Park) or D
(Drive) position while the vehicle is
moving reversing. This could cause an
accident or damage the transmission.
. Do not downshift abruptly on slip-
pery roads. This may cause a loss of
control.
