WARNING
Do not operate the push-button ignition switch
while driving the vehicle except in an emer-
gency. (The engine will stop when the ignition
switch is pushed 3 consecutive times or the
ignition switch is pushed and held for more
than 2 seconds.) If the engine stops while the
vehicle is being driven, this could lead to a
crash and serious injury.
Before operating the push-button ignition
switch, be sure to move the selector lever to the
P (Park) position (for automatic transmission
model) or the shift lever to the N (Neutral)
position (for manual transmission model).
INTELLIGENT KEY SYSTEM
The Intelligent Key system can operate the
ignition switch without it being taken out from
your pocket or purse. The operating environ-
ment and/or conditions may affect the Intelli-
gent Key system operation.
Some indicators and warnings for operation are
displayed on the dot matrix liquid crystal dis-
play between the speedometer and tachometer.
(See “DOT MATRIX LIQUID CRYSTAL DISPLAY” in
the “2. Instruments and controls” section.)
CAUTION
● Be sure to carry the Intelligent Key with you
when operating the vehicle.
● Never leave the Intelligent Key inside the
vehicle when you leave the vehicle.
● If the vehicle battery is discharged, the igni-
tion switch cannot be switched from the
LOCK position, and if the steering lock (if so
equipped) is engaged, the steering wheel
cannot be moved. Charge the battery as
soon as possible. (See “JUMP STARTING” in
the “6. In case of emergency” section.)
OPERATING RANGE FOR ENGINE
START FUNCTION
The Intelligent Key can only be used for starting
the engine when the Intelligent Key is within the
specified operating range
1.
When the Intelligent Key battery is almost dis-
charged or strong radio waves are present near
the operating location, the Intelligent Key sys-
tem’s operating range becomes narrower and
may not function properly.
If the Intelligent Key is within the operating
range, it is possible for anyone, even someone
who does not carry the Intelligent Key, to push
the ignition switch to start the engine.

AUTOMATIC TRANSMISSION
7 speed automatic transmission
The automatic transmission in your vehicle is
electronically controlled by a transmission con-
trol module to produce maximum efficiency and
smooth operation.
Shown on the following pages are the recom-
mended operating procedures for this transmis-
sion. 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 (Re-
verse), 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 posi-
tion 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.
DRIVING THE VEHICLE
5-12Starting and driving

1. Keep the foot brake pedal depressed andpush 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 (Re-
verse), 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 cau-
tion 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
● 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.
Shifting
To move the selector lever,
: Push the button while depressing the
brake pedal,
: Push the button,
: Just move the selector lever.
After starting the engine, fully depress the
brake pedal and shift the selector lever from P
(Park) to R (Reverse), N (Neutral), D (Drive), DS
(Drive Sport) or Manual shift mode position.

Push the button to shift into P (Park) or R
(Reverse). All other positions can be selected
without pushing the button.
WARNING
Apply the parking brake if the selector lever is
in any position while the engine is not running.
Failure to do so could cause the vehicle to move
unexpectedly or roll away and result in serious
personal injury or property damage.
CAUTION
Make sure the vehicle is completely stopped
and the transmission is in the P (Park) position.
P (Park) position :
Use this selector position when the vehicle is
parked or when starting the engine. Make sure
the vehicle is completely stopped. The brake
pedal must be depressed and the selector lever
button pushed in to move the selector lever from
the N (Neutral) position or any drive position to
the P (Park) position. Apply the parking brake.
When parking on a hill, apply the parking brake
first, then move the selector lever to the P (Park)
position.
CAUTION
Use this position only when the vehicle is com-
pletely stopped.
R (Reverse) :
Use this position to back up. Always be sure the
vehicle is completely stopped before selecting
the R (Reverse) position. The brake pedal must
be depressed and the selector lever button
pushed in to move the selector lever from the P
(Park) position, the N (Neutral) position or any
drive position to the R (Reverse) position.
N (Neutral) :
Neither forward nor reverse gear is engaged.
The engine can be started in this position. You
may shift to the N (Neutral) position and restart
a stalled engine while the vehicle is moving.
D (Drive) :
Use this position for all normal forward 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 transmission
changes to the “sporty” driving shift operation,
creating a more aggressive acceleration feeling
than the D (Drive) mode and providing a gear
change sensation 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.
5-14Starting and driving

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, or pulling the right-side or left-side
paddle shifter.
When shifting up, move the selector lever to the
+ (up) side or pull the right-side paddle shifter
(+)
A(if so equipped). The transmission shifts
to the higher range.
When shifting down, move the selector lever to
the (down) side or pull the left-side paddle shifter ()
B(if so equipped). 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.
When you pull the paddle shifter while in the D
(Drive) position, the transmission will shift to
the upper or lower range temporarily. The trans-
mission 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 sec-
onds.
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 economy.
● Moving the selector lever rapidly to the same
side twice will shift the ranges in succes-
sion.
● In the manual shift mode, the transmission
may not shift to the selected gear. This helps
maintain driving performance and reduces
the chance of vehicle damage or loss of con-
trol.
When this situation occurs, the Automatic
Transmission (AT) position indicator light (on
the dot matrix liquid crystal display) will
blink and the chime will sound.

●In the manual shift mode, the transmission
automatically shifts down to 1st gear before
the vehicle comes to a stop. When accelerat-
ing 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, depend-
ing 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 spinning and subse-
quent 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 re-
turn 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
