2014 INFINITI Q50 HYBRID automatic transmission

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.2-12).
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, contact
an INFINITI retailer. Even if the ignition
switch is switched to READY to drive
position, the system may shut-off sud-
denly. 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.5-10).)
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.

5-14Starting and driving
1. Apply the parking brake.
2. Move the shift lever to P (Park) posi-tion.
The INFINITI Direct Response Hybrid
®
System is designed not to operate if
the shift lever is not in the P (Park)
position.
3. Depress the brake pedal and push the ignition switch to start the hybrid
system. The READY to drive indicator
light will illuminate on the meter.
When starting the hybrid system at
very low outside temperatures, the
READY to drive indicator light will flash
and it may take longer for the READY to
drive indicator light to illuminate.
. The hybrid system may not start even
with the READY to drive indicator light
illuminated. Once the READY to drive
indicator light is illuminated you may
begin driving the vehicle.
. You may hear a sound in the engine
compartment when the brake pedal is
depressed with the hybrid system off.
This does not indicate a problem.
NOTE:
Care should be taken to avoid situations
that can lead to potential 12-volt battery discharge and potential no-start condi-
tions such as:
1.
Installation or extended use of electro-
nic accessories that consume 12-volt
battery power when the hybrid system
is not running (Phone chargers, GPS,
DVD players, etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the 12-volt battery may
need to be charged to maintain 12-volt
battery health.
AUTOMATIC TRANSMISSION
The automatic transmission in your vehicle
is electronically controlled by a transmis-
sion control module to produce maximum
efficiency 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.
STARTING THE INFINITI DIRECT RESPONSE
HYBRID®SYSTEM DRIVING THE VEHICLE

transmission shifts to the lower range.
When canceling the manual shift mode,
return the shift lever to the D (Drive)
position. The transmission returns to the
normal driving mode.
When you pull the paddle shifter (if so
equipped) while in the D (Drive) position,
the transmission will shift to the upper or
lower range temporarily. The transmission
will automatically return to the D (Drive)
position after a short period of time. If you
want to return to the D (Drive) position
manually, pull and hold the paddle shifter
for about 1.5 seconds.
In the manual shift mode, the shift range is
displayed in the vehicle information dis-
play.
Shift ranges up or down one by one as
follows:
1M?
/2M?
/3M?
/ 4M?
/5M?
/ 6M?
/7M
7M(7th):
Use this position for all normal forward
driving at highway speeds.
6
M(6th) and 5M(5th):
Use these positions when driving up long
slopes, or for engine braking when driving down long slopes.
4
M(4th), 3M(3rd) and 2M(2nd):
Use these positions for hill climbing or
engine braking on downhill grades.
1
M(1st):
Use this position when climbing steep hills
slowly or driving slowly through deep
snow, or for maximum engine braking on
steep downhill grades.
. Remember not to drive at high speeds
for extended periods of time in lower
than 7th gear. This reduces fuel econ-
omy.
. Moving the shift lever rapidly to the
same side twice will shift the ranges in
succession.
. In the manual shift mode, the transmis-
sion may not shift to the selected gear
or may automatically shift to the other
gear. This helps maintain driving per-
formance and reduces the chance of
vehicle damage or loss of control.
. When the transmission does not shift
to the selected gear, the Automatic
Transmission (AT) position indicator (in
the vehicle information display) will
blink and the buzzer will sound. .
In the manual shift mode, the transmis-
sion automatically shifts down to 1st
gear before the vehicle comes to a
stop. When accelerating again, it is
necessary to shift up to the desired
range.
Accelerator downshift —In D (Drive)
position —
For passing or hill climbing, fully depress
the accelerator pedal to the floor. This
shifts the transmission down into the lower
gear, depending on the vehicle speed.
Fail-safe
When the fail-safe operation occurs, note
that the transmission will be locked in any
of the forward gears according to the
condition.
If the vehicle is driven under extreme
conditions, such as excessive wheel spin-
ning and subsequent hard braking, the
fail-safe system may be activated. This will
occur even if all electrical circuits are
functioning properly. In this case, push
the ignition switch to the OFF position and
wait for 3 seconds. Then push the ignition
switch back to the ON position. The vehicle
should return to its normal operating
condition. If it does not return to its

Shift lock release
If the 12-volt battery charge is low or
discharged, the shift lever may not be
moved from the P (Park) position even with
the brake pedal depressed and the shift
lever button pushed.
To move the shift lever, perform the
following procedure:
1. Push the ignition switch to the OFF orLOCK position.
2. Apply the parking brake.
3. Remove the shift lock cover
*Ausing a
suitable tool. 4. Push down the shift lock
*Busing
mechanical key as illustrated.
5. Push the shift lever button
*Cand
move the shift lever to N (Neutral)
position
*Dwhile holding down the
shift lock.
If the lever cannot be moved out of P
(Park), have an INFINITI retailer check the
automatic transmission system as soon as
possible.
Adaptive Shift Control (ASC)
The adaptive shift control system automa-
tically operates when the transmission is
in the D (Drive) position and selects an
appropriate gear depending on the road
conditions such as uphill, downhill or
curving roads.
Control on uphill and curving roads:
A low gear is maintained that suits the
degree of the slope or curve to allow
smooth driving with a small number of
shifts.
Control on downhill roads:
The adaptive shift control system shifts to
a low gear that suits the degree of the
slope to reduce the number of times that
the brake must be used.
