moderate speed for a short distance
first, especially in cold weather. In cold
weather, keep the engine running for a
minimum of 2 - 3 minutes before
shutting it off. Starting and stopping
the engine over a short period of time
may make the vehicle more difficult to
start.
When racing the engine up to 4,000
rpm or more under no load condition,
the engine will enter the fuel cut mode.
5. To stop the engine, shift the selector lever to the P (Park) position (AT model)
or move the shift lever to the N
(Neutral) position (MT model), and push
the ignition switch to the OFF position.

driving.
DS (Drive Sport) modeGUID-E727EBD0-E14C-4AF7-955A-15CC054497DEMove the selector lever from D (Drive) to
the left into the manual shift gate. The
transmission position indicator in the
meter shows“DS”.
In the DS (Drive Sport) mode, the transmis-
sion changes to the “sporty”driving shift
operation, creating a more aggressive
acceleration feeling than the D (Drive)
mode and providing a gear change sensa-
tion when the driver accelerates quickly.
When the driver selects the manual shift
mode using the selector lever (or the
paddle shifter) during the DS (Drive Sport)
mode operation, the driver must move the
selector lever from DS (Drive Sport) to D
(Drive) and back again to re-select the DS
(Drive Sport) mode.

driving at highway speeds.
M6 (6th) andM5 (5th):GUID-D73A39BF-43C8-459F-9C24-47B7F579C407Use this position when driving up long
slopes, or for engine braking when driving
down long slopes.
M4 (4th),M3 (3rd) andM2 (2nd):GUID-D73A39BF-43C8-459F-9C24-47B7F579C407Use for hill climbing or engine braking on
downhill grades.
M1 (1st):GUID-D73A39BF-43C8-459F-9C24-47B7F579C407Use 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 selector 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.
This helps maintain driving perfor-
mance and reduces the chance of
vehicle damage or loss of control.
When this situation occurs, the Auto-
matic Transmission (AT) position indi-
cator light (on the dot matrix liquid
crystal display) will blink and the chime
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.

GUID-06BB20B5-DB70-4A4E-BFAD-8895E4D6A7ADFor 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-safeGUID-95D61986-6CBA-49FB-BC3E-01783BEA6F87When 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.

Adaptive shift control (ASC)GUID-AEB4A362-DBFB-4302-BBDA-E06349BDD353The adaptive shift control system automa-
tically operates when the transmission is
in the "D" (drive) and "DS" (Drive Sport)
position and selects an appropriate gear
depending on the road conditions such as
uphill, downhill or curving roads.
Control on uphill and curving roads:
GUID-D73A39BF-43C8-459F-9C24-47B7F579C407A 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:
GUID-D73A39BF-43C8-459F-9C24-47B7F579C407The 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:
GUID-D73A39BF-43C8-459F-9C24-47B7F579C407A 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.
