AUTOMATIC TRANSMISSION
7 speed 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 engine, fully depress the
foot brake pedal and push the selector
lever button before shifting the selector
lever to the R (Reverse), N (Neutral), D
(Drive), DS (Drive Sport) or Manual shift
mode position. Be sure the vehicle is fully
stopped before attempting to shift the
selector lever.
This automatic transmission 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 position is ON.The selector 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 selector 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), DS
(Drive Sport) 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 P (Park) or R (Reverse)
while vehicle is moving forward. Never shift to P (Park), D (Drive) or DS (Drive
Sport) while vehicle is moving rearward.
Failure to do so could cause you to lose
control and have an accident.
CAUTION
.
Except in an emergency, do not shift to
the N (Neutral) position while driving.
Coasting with the transmission in the N
(Neutral) position may cause serious
damage to the transmission.
. When stopping the vehicle on an uphill
grade, do not hold the vehicle by
depressing the accelerator pedal. The
foot brake should be used for this
purpose.
. Do not downshift abruptly on slippery
roads. This may cause a loss of control.
DRIVING THE VEHICLE
Page 327 of 498

5-16Starting and driving
DS (Drive Sport) mode
Move 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 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.
Manual shift mode
When the selector lever is in the DS (Drive
Sport) position, the transmission is ready
for the manual shift mode. Shift ranges can
be selected manually by moving the
selector lever up or down.
When shifting up, move the selector lever
to the + (up) side. The transmission shifts
to the higher range.
When shifting down, move the selector lever to the
−(down) side. The transmis-
sion shifts to the lower range.
When canceling the manual shift mode,
return the selector lever to the D (Drive)
position. The transmission returns to the
normal driving mode.
In the manual shift mode, the shift range is
displayed on the position indicator in the
meter.
Shift ranges up or down one by one as
follows:
M1 ?M2?M3?M4?M5?M6?M7
///// /
M7 (7th):
Use these positions for all normal forward
driving at highway speeds.
M6 (6th) andM5 (5th):
Use this position when driving up long
slopes, or for engine braking when driving
down long slopes.
M4 (4th),M3 (3rd) andM2 (2nd):
Use these positions for hill climbing or
engine braking on downhill grades.
M1 (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 selector lever rapidly to the
same side twice will shift the ranges in
succession. However, if this motion is
done rapidly, the second shifting may
not be completed properly.
. In the manual shift mode, the transmis-
sion may not shift to the selected gear
or may automatically shift to the other
gear depending on conditions. This
helps maintain driving performance
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
light (on the dot matrix liquid crystal
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
Page 328 of 498

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.

Shift lock release
If the battery charge is low or discharged,
the selector lever may not be moved from
the P (Park) position even with the brake
pedal depressed and the selector lever
button pushed.
To move the selector lever, perform the
following procedure:
1. Push the ignition switch to the OFF or
LOCK position.
2. Apply the parking brake.
3. Remove the shift lock cover
*Ausing a
suitable tool. 4. Push down the shift lock
*Bas
illustrated.
5. Push the selector lever button
*Cand
move the selector lever to N (Neutral)
position
*Dwhile holding down the
shift lock.
Push the ignition switch to the ON posi-
tion. Now the vehicle may be moved to the
desired location.
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) 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:
A low gear is maintained that suits the
degree of the slope or curve to allow
smooth driving with a small number of
shifts.
Starting and driving5-17
Page 329 of 498

5-18Starting and driving
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.WARNING
.
Be sure the parking brake is fully
released before driving. Failure to do so
can cause brake failure and lead to an
accident.
. Do not release the parking brake from
outside the vehicle.
. Do not use the gear shift in place of the
parking brake. When parking, be sure
the parking brake is fully engaged.
. Do not leave children unattended in a
vehicle. They could release the parking
brake and cause an accident.

WARNING
.Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite and
cause a fire.
. Never leave the engine running while the
vehicle is unattended.
. Do not leave children unattended inside
the vehicle. They could unknowingly
activate switches or controls. Unat-
tended children could become involved
in serious accidents. .
Safe parking procedures require that
both the parking brake be applied and
the transmission be placed in the P
(Park) position. Failure to do so could
cause the vehicle to move unexpectedly
or roll away and result in an accident.
. Make sure the automatic transmission
selector lever has been pushed as far
forward as it can go and cannot be
moved without depressing the foot
brake pedal.
1. Firmly apply the parking brake.

contaminated with corrosive acid.
9. Put the battery cover on. Do not attempt to start the engine by
pushing.
CAUTION
.
Automatic transmission models cannot
be push-started or tow-started. Attempt-
ing to do so may cause transmission
damage.
. Three way catalyst equipped models
should not be started by pushing since
the three way catalyst may be damaged.
. Never try to start the vehicle by towing
it; when the engine starts, the forward
surge could cause the vehicle to collide
with the tow vehicle.
CAUTION
.Do not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
. To avoid the danger of being scalded,
never remove the radiator cap while the
engine is still hot. When the radiator cap
is removed, pressurized hot water will
spurt out, possibly causing serious
injury.
. Do not open the hood if steam is coming
out.
If your vehicle is overheating (indicated by
an extremely high temperature gauge
reading), or if you feel a lack of engine
power, detect abnormal noise, etc., take
the following steps:
1. Move the vehicle safely off the road,
apply the parking brake and move the
selector lever to the P (Park) position.
Do not stop the engine.
2. Turn off the climate control. Open all the windows, move the heater or air
conditioner temperature control to
maximum hot and fan control to high

Two-wheel drive models
TOWING RECOMMENDED BY INFINITI
Two-Wheel Drive (2WD) models
INFINITI recommends that your vehicle be
towed with the driving (rear) wheels off the
ground or place the vehicle on a flat bed
truck as illustrated.
CAUTION
. Never tow automatic transmission mod-
els with the rear wheels on the ground
or four wheels on the ground (forward or
backward), as this may cause serious and expensive damage to the transmis-
sion. If it is necessary to tow the vehicle
with the front wheels raised, always use
towing dollies under the rear wheels.
. When towing rear wheel drive models
with the front wheels on the ground or
on towing dollies: Push the ignition
switch to the ACC or ON position, and
secure the steering wheel in a straight-
ahead position with a rope or similar
device.
