5-20Starting and driving
5. Push the shift lever buttonand move
the shift lever to N (Neutral) position
while holding down the shift lock.
If the lever cannot be moved out of P (Park),
have the automatic transmission system
checked as soon as possible. It is recom-
mended you visit an INFINITI retailer for this
service.
Adaptive Shift Control (ASC)
The adaptive shift control system automati-
cally operates when the transmission is in
the D (Drive) position and selects an appro-
priate 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 main-
tains 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 position
in certain situations based on road informa-
tion 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. However, 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 navi-
gation system.
— When the navigation system cannot accurately detect the location of the
vehicle.
— When the vehicle is driving on a road- way that is not recognized by the
navigation system.
— When the actual roadway differs from the map information on the naviga-
tion system due to road construction,
traffic lane obstructions, etc.

.The NAVI Shift Control may not operate
properly in the following situations:
— If the vehicle’s transmission, engine, and/or navigation system, and/or
GPS is malfunctioning.
— If the vehicle speed is higher than 74 MPH (120 km/h) or lower than 19
MPH (30 km/h) and/or transmission
gear is outside the operating range of
the system.
— When the vehicle is driving on a free- way.
— When the vehicle is driving on a gentle curve
— When the vehicle is driving with the shift lever except in the D (Drive)
position.
