DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of alcohol or
drugs. Alcohol in the bloodstream reduces
coordination, delays reaction time and im-
pairs judgement. Driving after drinking
alcohol increases the likelihood of being
involved in an accident injuring yourself and
others. Additionally, if you are injured in an
accident, alcohol can increase the severity
of the injury.
INFINITI is committed to safe driving.
However, you must choose not to drive
under the influence of alcohol. Every year
thousands of people are injured or killed in
alcohol-related accidents. Although the
local laws vary on what is considered to
be legally intoxicated, the fact is that
alcohol affects all people differently and
most people underestimate the effects of
alcohol.
Remember, drinking and driving don’t mix!
And that is true for drugs, too (over-the-
counter, prescription, and illegal drugs). Don’t drive if your ability to operate your
vehicle is impaired by alcohol, drugs, or
some other physical condition.
ALL-WHEEL DRIVE (AWD) DRIVING
SAFETY PRECAUTIONS
WARNING
.
Do not drive beyond the performance
capability of the tires, even with AWD
engaged. Accelerating quickly, sharp
steering maneuvers or sudden braking
may cause loss of control.
. Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels. Install tire chains on the rear
wheels when driving on slippery roads
and drive carefully.
. This vehicle is not designed for offroad
(rough road) use. Do not drive on sandy
or muddy roads that tires may get stuck
in.
. For AWD equipped vehicles, do not
attempt to raise two wheels off the
ground and shift the transmission to
any D (Drive) or R (Reverse) position with
the engine running. Doing so may result

in drivetrain damage or unexpected
vehicle movement which could result in
serious vehicle damage or personal
injury.
. Do not attempt to test an AWD equipped
vehicle on a 2-wheel dynamometer,
(such as the dynamometers used by
some states for emissions testing), or
similar equipment even if the other two
wheels are raised off the ground. Make
sure you inform test facility personnel
that your vehicle is equipped with AWD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or
personal injury.
. When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.WARNING
Do not operate the push-button ignition
switch while driving the vehicle except in an
emergency. (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 trans-
mission 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
environment and/or conditions may affect
the Intelligent Key system operation.
Some indicators and warnings for opera-
tion are displayed on the dot matrix liquid
crystal display between the speedometer
and tachometer. (See “Dot matrix liquidcrystal display”
(P.2-20).)
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
ignition switch cannot be switched from
the LOCK position. Charge the battery as
soon as possible. (See “Jump starting”
(P.6-8).)

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
.
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.

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 (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.
SSD0599
Paddle shifters
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 transmission 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 tempora-
rily. The transmission 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 seconds.
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.
. 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.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.SSD0598
