transmission INFINITI Q50 2014 User Guide

5-18Starting and driving
.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 normal operating condition, have an
INFINITI retailer check the transmission
and repair if necessary.

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, and uses the engine braking to
reduce the number of times that the brake must be used.
Control on winding roads:
A low gear is maintained on continuous
curves that involve repeated acceleration
and deceleration, so that smooth accelera-
tion is available instantly when the accel-
erator pedal is depressed.
NOTE:
. Adaptive shift control may not operate
when the transmission oil temperature
is low immediately after the start of
driving or when it is very hot.
. During some driving situations, hard
braking for example, the adaptive shift
control may automatically operate. The
transmission may automatically shift
to a lower gear for engine braking. This
increases engine speed but not vehicle
speed. Vehicle speed is controlled by
the accelerator pedal when the vehicle
is in the Adaptive shift control mode.
. When the adaptive shift control oper-
ates, the transmission sometimes
maintains a lower gear for a longer
period of time than when adaptive shift
control is not operating. Engine speed
will be higher for a specific vehicle
speed while ASC system is operating than when ASC is not operating.
NAVI Shift Control (if so equipped)
NAVI Shift Control automatically adjusts
the Automatic Transmission (AT) gear posi-
tion in certain situations based on road
information from the navigation system.
When the navigation system detects that
the vehicle is approaching a curved road,
NAVI Shift Control will adjust the gear
position if needed to help the driver run
through the curve smoothly.
Precaution on NAVI shift control:
.
The NAVI Shift Control does not provide
steering input or automated driving on
a curve. It is not a speed limit support
system and will not modify your speed
according to local speed limits.
. The NAVI Shift Control is a convenient
system intended to help the vehicle
move through a curve smoothly. How-
ever, the driver must always drive
safely and use the brake pedal if
needed.
. The NAVI Shift Control may be delayed
or not operate properly in the following
situations, because this function uses
the road information provided by the
navigation system.

ECO MODE
Assists the driver’s eco-driving. The engine
and transmission points are adjusted for
improved fuel economy, providing such a
driving features as smooth starting or
constant cruising.
NOTE:
Selecting the ECO mode will not necessa-
rily improve fuel economy as many driving
factors influence its effectiveness.
Operation
Select the ECO mode using the INFINITI
Drive Mode Selector. The ECO drive indi-
cator light on the instrument panel illumi-nates.
When the accelerator pedal is depressed
within the range of economy drive, the ECO
drive indicator light illuminates in green.
When the accelerator pedal is depressed
above the range of economy drive, the ECO
drive indicator light turns off. For ECO
pedal system equipped models, see
“ECO
pedal system” (P.5-22).
The ECO drive indicator light will not
illuminate in the following cases:
. When the shift lever is in the R (Reverse)
position.
. When the vehicle speed is below 2 MPH
(3.2 km/h) or over 90 MPH (144 km/h).
. When the cruise control (if so equipped)
or the Intelligent Cruise Control (ICC)
system (if so equipped) is operated.
ECO pedal system (if so equipped)
The ECO pedal system helps assist the
driver to improve fuel economy by increas-
ing the reaction force of the accelerator
pedal. When the ECO drive indicator light is
blinking or remains off, the ECO pedal
system increases the reaction force of the
accelerator pedal.
JVS0303X
When the ECO drive indicator illuminates in
green, the accelerator reaction force is
normal. When the ECO drive indicator light
is blinking or remains off, the ECO pedal
system increases the reaction force of the
accelerator pedal.
The ECO pedal system may not vary
accelerator reaction force under the follow-
ing conditions:
. When the shift lever is in the N (Neutral)
or R (Reverse) position.
. When Intelligent Cruise Control (ICC) is
being operated.
If the ECO pedal system malfunctions, it
will cancel automatically. The ECO pedal

system will not vary the reaction force of
the accelerator pedal.
When the INFINITI Drive Mode Selector is
rotated from the ECO mode to another
mode (STANDARD, SPORT, SNOW or PER-
SONAL) while the ECO pedal system is
operating, the ECO pedal system continues
to operate until the accelerator pedal is
released.
If the accelerator pedal is depressed
quickly, the ECO pedal system will not
increase the reaction force of the accelera-
tion pedal. The ECO pedal system is not
designed to prevent the vehicle from
accelerating.
Adjusting the ECO pedal system reaction
force:
The ECO pedal system reaction force can
be adjusted. The reaction force setting will
be maintained until the setting is changed
even if the engine is turned off.

PARKING/PARKING ON HILLS

driver (for example, avoidance scenes).WARNING
.Never rely solely on the hill start assist
system to prevent the vehicle from
moving backward on a hill. Always drive
carefully and attentively. Depress the
brake pedal when the vehicle is stopped
on a steep hill. Be especially careful
when stopped on a hill on frozen or
muddy roads. Failure to prevent the
vehicle from rolling backwards may
result in a loss of control of the vehicle
and possible serious injury or death.
. The hill start assist system is not
designed to hold the vehicle at a
standstill on a hill. Depress the brake
pedal when the vehicle is stopped on a
steep hill. Failure to do so may cause the
vehicle to roll backwards and may result
in a collision or serious personal injury.
. The hill start assist system may not
prevent the vehicle from rolling back-
wards on a hill under all load or road
conditions. Always be prepared to de-
press the brake pedal to prevent the
vehicle from rolling backwards. Failure to
do so may result in a collision or serious
personal injury.
The hill start assist system automatically
keeps the brakes applied to help prevent
the vehicle from rolling backwards in the
time it takes the driver to release the brake
pedal and apply the accelerator when the
vehicle is stopped on a hill.
The hill start assist system will operate
automatically under the following condi-
tions:
.The transmission is shifted to a forward
or reverse gear.
. The vehicle is stopped completely on a
hill by applying the brake.
The maximum holding time is 2 seconds.
After 2 seconds the vehicle will begin to
roll back and the hill start assist system
will stop operating completely.
The hill start assist system will not operate
when the transmission is shifted to the N
(Neutral) or P (Park) position or on a flat
and level road.
