Remember, drinking and driving don't
mix!
And that's 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 (for AWD
models)
WARNINGO Do not drive beyond the performance ca-
pability of the tires, even with AWD en-
gaged. Accelerating quickly, sharp
steering maneuvers or sudden braking
may cause loss of control.
O 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. O This vehicle is not designed for off-road
(rough road) use. Do not drive on sandy
or muddy roads that tires may get stuck
in.
O Do not place an AWD equipped vehicle
on a two wheel dynamometer or raise
two wheels off the ground and shift the
transmission to any D (drive) or R (re-
verse) position. Doing so may result in
transmission damage or unexpected ve-
hicle movement which could result in se-
rious vehicle damage or personal injury.
O Never operate the accelerator pedal with
any wheels raised and the other wheels
on the ground while jacking up or with
any wheels on a roller and the other
wheels on the ground. Otherwise, the
vehicle could lurch forward or backward.
O When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively. AUTOMATIC TRANSMISSION The ignition lock is designed so the key
cannot be turned to the LOCK position
and removed until the selector lever is
moved to the P (Park) position.
When removing the key from the ignition
switch, make sure the selector lever is in
the P (Park) position.
If the selector lever is not returned to the
P (Park) position, the key cannot be
moved to the LOCK position. SSD0392

sition while driving. The steering wheel will
lock. This may cause the driver to lose con-
trol of the vehicle and could result in serious
vehicle damage and/or personal injury.
KEY POSITIONS The ignition switch includes an anti-theft
steering lock device.
LOCK (Normal parking position) (0)
The ignition key can only be removed
when the ignition switch is in this posi-
tion. OFF (1)
The engine can be turned off without
locking the steering wheel.
The ignition lock is designed so that the
key cannot be turned to the LOCK position
and removed until the selector lever is
moved to the P position (for automatic
transmission) or the key is pushed in
while turning the key between the ACC
and LOCK positions.
ACC (Accessories) (2)
This position activates electrical accesso-
ries when the engine is not running.
ON (Normal operating position) (3)
This position activates ignition system in
addition to electrical accessories.
START (4)
This position activates the starter motor,
starting the engine.
INFINITI VEHICLE IMMOBILIZER
SYSTEM The INFINITI Vehicle Immobilizer System
will not allow the engine to start without
the use of the registered key. If the engine fails to start using a regis-
tered key (for example, when interference
is caused by another registered key, an
automated toll road device or automated
payment device on the key ring), restart
the engine using the following proce-
dures:
1. Leave the ignition switch in the ON po-
sition for approximately 5 seconds.
2. Turn the ignition switch to the OFF or
LOCK position and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the
device (which may have caused the in-
terference) away from the registered
key.
If this procedure allows the engine to
start, INFINITI recommends placing the
registered key on a separate key ring to
avoid interference from other devices.

The ignition lock is designed so that the
ignition switch cannot be turned to the
LOCK position and removed until the se-
lector lever is moved to the P (Park) posi-
tion.
When turning the ignition switch, make
sure the selector lever is in the P position.
If the selector lever is not returned to the
P position, the ignition switch cannot be
moved toward the LOCK position.
When the ignition switch cannot be
turned toward the LOCK position, proceed
as follows: 1. Move the selector lever into the P po-
sition.
2. Turn the ignition switch slightly in the
ON direction.
3. Turn the key toward the LOCK posi-
tion.
The selector lever can be moved from the P
position if the ignition switch is in the ON
position and the foot brake pedal is de-
pressed.
There is an OFF position in between the
LOCK and ACC positions, although it does
not show on the lock cylinder. When the
ignition is in the OFF position the steering
wheel is not locked.
In order for the steering wheel to be
locked, it must be turned about 1/6 of a
turn counterclockwise from the straight
up position.
To lock the steering wheel, turn the igni-
tion switch to the LOCK position. To unlock
the steering wheel, push the ignition
switch in and turn it gently while rotating
the steering wheel slightly right and left.
If the battery of the vehicle equipped with
the Intelligent Key system is discharged,
the ignition switch cannot be turned from the LOCK position, even using the me-
chanical key or valet key.
WARNING Never turn the ignition switch to the LOCK
position while driving. The steering wheel
will lock. This may cause the driver to lose
control of the vehicle and could result in se-
rious vehicle damage and/or personal injury.

SYSTEM The INFINITI Vehicle Immobilizer System
will not allow the engine to start without
the use of the registered key.
If the engine does not start using a regis-
tered key (for example, when interference
is caused by another registered key, an
automated toll road device or an auto-
mated payment device on the key ring),
restart the engine using the following pro-
cedures:
1. Leave the ignition switch in the ON po-
sition for approximately 5 seconds.
2. Turn the ignition switch to the OFF or
LOCK position and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the
device (which may have caused the in-
terference) separate from the regis-
tered key.
If this procedure allows the engine to
start, INFINITI recommends placing the
registered key on a separate key ring to
avoid interference from other devices. O Make sure the area around the vehicle
is clear.
O Maintenance items should be checked
periodically, for example, each time
you check engine oil.
O Check that all windows and lights are
clean.
O Visually inspect tires for their appear-
ance and condition. Also check tires
for proper inflation.
O Lock all doors.
O Position seat and adjust head re-
straints.
O Adjust inside and outside mirrors.
O Fasten seat belts and ask all passen-
gers to do likewise.
O Check the operation of warning lights
when the ignition key is turned to the
ON position. See ªWarning/indicator
lights and audible remindersº in the

D (Drive):
Use this position for all normal forward
driving.
Manual shift mode When the selector lever is shifted from
the D position to the manual shift gate
with the vehicle stopped or while driving,
the transmission enters the manual shift
mode. Shift range can be selected manu-
ally.
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: 1 M
!
à 2 M
!
à 3 M
!
à 4 M
!
à 5 M
5 M
(5th):
Use this position for all normal forward
driving.
4 M
(4th):
For driving up or down long slopes where
engine braking would be advantageous. 3 M
(3rd) and 2 M
(2nd):
Use for hill climbing or engine braking on
downhill grades.
1 M
(1st):
Use this position when climbing steep
hills slowly or driving slowly through
deep snow, sand or mud, or for maximum
engine braking on steep downhill grades.
O Remember not to drive at high speeds
for extended periods of time in lower
than 4 M
range. This reduces gas mile-
age.
O When shifting up, move the selector
lever to the + (up) side. (Shifts to
higher range.)
O When shifting down, move the se-
lector lever to the þ (down) side.
(Shifts to lower range.)
O Moving the selector lever rapidly to
the same side twice will shift the
ranges in succession.
O When canceling the manual shift
mode, return the selector lever to the
D position. The transmission returns
to the normal driving mode. O 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 ve-
hicle damage or loss of control.
In the manual shift mode, the transmission
automatically shifts down to 1st gear be-
fore the vehicle comes to a stop. When ac-
celerating again, it is necessary to shift up
to the desired range.
Accelerator downshift
Ð In D position Ð 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, the
automatic transmission will be locked in
the 4th gear.
If the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
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, turn the ignition

switch to the OFF position and wait for 3
seconds. Then turn the key 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 dealer check the trans-
mission 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, release the
shift lock and push the selector lever but-
ton. The selector lever can be moved to
the N (Neutral) position. However, the
steering wheel will be locked unless the
ignition switch is turned to the ON posi-
tion. To release the shift lock, complete the fol-
lowing procedure:
1. Turn the ignition switch to the LOCK
position and remove the key.
2. Apply the parking brake.
3. Remove the shift lock cover
q A
using a
suitable tool.
4. Insert a suitable tool in the shift lock
slot, and push down
q B
.
5. Push the selector lever button
q C
and
move the selector lever to the N (Neu-
tral) position
q D
while holding down
the shift lock.
6. Turn the ignition switch to the ON po-
sition to unlock the steering wheel.
Now the vehicle may be moved to the
desired location.
If the lever cannot be moved out of the P
(Park) position, have an INFINITI dealer
check the automatic transmission system
as soon as possible. SSD0477

The full-time all-wheel drive (AWD) system
automatically changes the driving mode. ALL-WHEEL DRIVE (AWD) WARNING
LIGHT The AWD warning light is located on the
instrument panel.
The AWD warning light comes on when
the ignition switch is turned to the ON po-
sition. It turns off soon after the engine is
started.
If any malfunction occurs in the AWD sys-
tem while the engine is running, the
warning light will come on.
The warning light may blink rapidly (about
twice per second) while trying to free a
stuck vehicle due to high power train oil
temperature. The driving mode may
change to 2 wheel drive. If the warning
light blinks rapidly during operation, stop
the vehicle with the engine idling in a
safe place immediately. Then if the light
goes off after a while, you can continue
driving.
A large difference between the diameters
of front and rear wheels will make the
warning light blink slowly (about once per
two seconds). Pull off the road in a safe
area, and idle the engine. Check that all
tire sizes are the same, tire pressure is
correct and tires are not worn. If the warning light is blinking after the
above operation, have your vehicle
checked by an INFINITI dealer as soon as
possible.
WARNING Do not attempt to test an AWD equipped vehicle
with two wheels on a two wheel dynamometer
and the other two wheels raised. Doing so may
result in transmission damage or unexpected
vehicle movement which could result in serious
vehicle damage or personal injury.
CAUTION O Do not operate the engine on a free roller
when any of the wheels are raised.
O If the warning light comes on while
driving there may be a malfunction in the
AWD system. Reduce the vehicle speed
and have your vehicle checked by an
INFINITI dealer as soon as possible.
O Never drive on dry hard surface roads in
the SNOW mode, as this will over load
the power train and may cause a serious
malfunction.SSD0336AALL-WHEEL DRIVE (AWD) (if so equipped)

there is a smell of exhaust fumes, imme-
diately locate the trouble and correct it.
See ªPrecautions when starting and
drivingº in the ª5. Starting and drivingº
section for exhaust gas (Carbon mon-
oxide).
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks after
the vehicle has been parked for a while.
Water dripping from the air conditioner
after use is normal. If you should notice
any leaks or if gasoline fumes are evi-
dent, check for the cause and have it cor-
rected immediately.
Power steering fluid level* and lines:
Check the level when the fluid is cold and
the engine is turned off. Check the lines
for proper attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, de-
formation, deterioration or loose connec-
tions.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control
dust. It is very important to remove these
substances, otherwise rust will form on the floor pan, frame, fuel lines and
around the exhaust system. At the end of
winter, the underbody should be thor-
oughly flushed with plain water, being
careful to clean those areas where mud
and dirt may accumulate. For additional
information, see ªCleaning exteriorº in
the ª7. Appearance and careº section.
Windshield washer fluid*: Check that
there is adequate fluid in the tank. When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury
to yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING O Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from
moving. For a manual transmission,
move the shift lever to N (Neutral) posi-
tion. For an automatic transmission
models, move the selector lever to P
(Park).
O Be sure the ignition key is in the OFF or
LOCK position when performing any
parts replacement or repairs.
O If you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans, belts
and any other moving parts.
O It is advisable to secure or remove any
loose clothing and remove any jewelry,MAINTENANCE PRECAUTIONS

such as rings, watches, etc. before work-
ing on your vehicle.
O Always wear eye protection whenever
you work on your vehicle.
O If you must run the engine in an enclosed
space such as a garage, be sure there is
proper ventilation for exhaust gases to
escape.
O Never get under the vehicle while it is
supported only by a jack. If it is neces-
sary to work under the vehicle, support it
with safety stands.
O Keep smoking materials, flame and
sparks away from the fuel tank and bat-
tery.
O On gasoline engine models with the Mul-
tiport Fuel Injection (MFI) System, the
fuel filter or fuel lines should be serviced
by an INFINITI dealer because the fuel
lines are under high pressure even when
the engine is off. CAUTION O Do not work under the hood while the en-
gine is hot. Turn the engine off and wait
until it cools down.
O Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
O Never leave the engine or automatic
transmission related component har-
ness connector disconnected while the
ignition switch is in the ON position.
O Avoid contact with used engine oil and
coolant. Improperly disposed engine oil,
engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
This ª8. Maintenance and do-it-yourselfº
section gives instructions regarding only
those items which are relatively easy for
an owner to perform. A genuine INFINITI Service Manual is also
available. See ªOwner's Manual/Service
Manual order informationº in the ª9.
Technical and consumer informationº sec-
tion.
You should be aware that incomplete or
improper servicing may result in oper-
ating difficulties or excessive emissions,
and could affect your warranty coverage.
If in doubt about any servicing, have it
done by an INFINITI dealer.
