CAUTION
Do not leave the vehicle with the ignition
switch in ACC or ON positions when the
engine is not running for an extended pe-
riod. This can discharge the battery.
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 the registered key,
it may be due to interference caused by another
registered key, an automated toll road device or
automated payment device on the key ring. Re-
start the engine using the following procedures:1. Leave the ignition switch in the ON position for approximately 5 seconds.
2. Turn the ignition switch to the OFF or LOCK position and wait approximately 5 seconds.
3. Repeat step 1 and 2 again. 4. Restart the engine while holding the device
(which may have caused the interference)
separate from the registered key.
If the no start condition re-occurs, INFINITI rec-
ommends placing the registered key on a sepa-
rate key ring to avoid interference from other
devices. ●
Make sure the area around the vehicle is
clear.
● Check fluid levels such as engine oil, cool-
ant, brake fluid, and window washer fluid as
frequently as possible, or at least whenever
you refuel.
● Check that all windows and lights are clean.
● Visually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
● Check that all doors are closed.
● Position seat and adjust head restraint.
● Adjust inside and outside mirrors.
● Fasten seat belts and ask all passengers to
do likewise.
● Check the operation of warning lights when
the ignition switch is placed in the ON
D
position. See “Warning/indicator lights and
audible reminders” in the “Instruments and
controls” section of this manual.

If:1. The engine coolant temperature is not re- duced.
2. The air conditioning cooling function does not turn back ON.
3. The engine oil pressure warning/engine coolant temperature high indicator
il-
luminates, this may indicate a malfunction.
Move the vehicle off the road in a safe area
and allow the engine to cool. If after check-
ing the oil and coolant, the
remains
on, do not continue to drive and call an
INFINITI dealer.
The malfunction indicator lamp may also come
ON. You do not need to have your vehicle towed,
unless it remains on, but have it inspected soon
by an INFINITI dealer. See “Warning/Indicator
Lights and Audible reminders” in the “Instruments
and Controls” section of this manual.
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced
speed may be lower than other traffic,
which could increase the chance of a col-
lision. Be especially careful when driving.
If the vehicle cannot maintain a safe driv-
ing speed, pull to the side of the road in a
safe area. Allow the engine to cool and
return to normal operation. See “If your
vehicle overheats” in the “In case of emer-
gency” section of this manual.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause se-
rious damage to the engine almost imme-
diately. Such damage is not covered by
warranty. Turn off the engine as soon as it
is safe to do so.
AUTOMATIC TRANSMISSION
WARNING
● Do not depress the accelerator pedal
while shifting from P (Park) or N (Neu-
tral) to R (Reverse) , or L (Low) . 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 the vehicle is moving. This could
cause an accident.
CAUTION
● When stopping the vehicle on an uphill
grade, do not hold the vehicle by de-
pressing 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.
The automatic transmission in your vehicle is
electronically controlled to produce maximum
power and smooth operation.

Shift lock release
If the battery is discharged, the shift selector may
not be moved from the P (Park) position even with
the brake pedal depressed.
To move the shift selector, release the shift lock.
The shift selector can be moved to N (Neutral) .
However, the steering wheel will be locked un-
less the ignition switch is turned to the ON posi-
tion. This allows the vehicle to be moved if the
battery is discharged.
To push the shift lock release, complete the fol-
lowing procedure:1. Place the ignition switch in the LOCK posi-
tion.
2. Apply the parking brake.
3. Remove the shift lock release cover as shown.
4. Insert a small screwdriver in the shift lock release slot and push down.
5. Move the shift selector to the N (Neutral) position while holding down the shift lock
release.
6. Turn the ignition switch to the ON position to unlock the steering wheel. Now the vehicle
may be moved to the desired location.
If the shift selector cannot be moved out of P
(Park) , have an INFINITI dealer check the auto-
matic transmission system as soon as possible.
WARNING
If the shift selector cannot be moved from
the P (Park) position while the engine is
running and the brake pedal is depressed,
the stop lights may not work. Malfunction-
ing stop lights could cause an accident
injuring yourself and others.
Accelerator downshift
— in D position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
Fail-safe
When the fail-safe operation occurs, please note
that the transmission will be locked in any of the
forward gears according to the condition.
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, place the ignition
switch in the OFF position and wait for 3
seconds. Then turn 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 dealer check
the transmission and repair it if necessary.

If the indicator stays on, it may indicate that
the Preview Function is malfunctioning
(the brake is operative) . Although the Ve-
hicle is still driveable under normal condi-
tions, have the vehicle checked at an
INFINITI dealer.
Sensor maintenance
The sensor for the Preview Function, is common
with Intelligent Cruise Control and is located
below the front bumper.
To keep the Preview Function operating properly,
be sure to observe the following:● Always keep the sensor clean. Wipe with a
soft cloth carefully so as not to damage
them.
● Do not impact the areas around the sensor.

cated on the sensor. Doing so could cause
failure or malfunction. If the sensor installa-
tion part is deformed due to an accident,
contact an INFINITI dealer.
● Do not attach a sticker (including transpar-
ent material) or install an accessory near the
sensor. This could cause failure or malfunc-
tion.
CAUTION
During the first 1,200 miles (2,000 km) ,
follow these recommendations to obtain
maximum engine performance and en-
sure the future reliability and economy of
your new vehicle. Failure to follow these
recommendations may result in short-
ened engine life and reduced engine
performance.
● Avoid driving for long periods at constant
speed, either fast or slow, and do not run the
engine over 4,000 rpm.
● Do not accelerate at full throttle in any gear.
● Avoid quick starts.
● Avoid hard braking as much as possible.
● Do not tow a trailer for the first 500 miles
(800 km) . Your engine, axle or other parts
could be damaged. ●
Accelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
● Drive at moderate speeds on the highway.
Driving at high speed lowers fuel economy.
● Avoid unnecessary stopping and braking.
Maintain a safe distance behind other ve-
hicles.
● Use a proper gear range which suits road
conditions. On level roads, shift into high
gear as soon as possible.
● Avoid unnecessary engine idling.
● Keep your engine tuned up.
● Follow the recommended periodic mainte-
nance schedule.
● Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.

●When cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag.
● For vehicles equipped with
, use 4H or
4L position only when necessary. Four-
wheel drive operation lowers fuel economy.
WARNING
● For 4WD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to
any drive or reverse position with the
engine running. Doing so may result in
drivetrain damage or unexpected ve-
hicle movement which could result in
serious vehicle damage or personal
injury.
● Do not attempt to test a 4WD 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 4WD
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 per-
sonal injury.
CAUTION
● Do not drive the vehicle in the 4H or 4LO
position on dry hard surface roads. Driv-
ing on dry, hard surfaces in 4H or 4LO
may cause unnecessary noise, tire wear
and increased fuel consumption.
If the 4WD warning light turns on when
you are driving on dry hard surface
roads:
– in the 4H position, shift the 4WD shift switch to 2WD.
– in the 4LO position, stop the vehicle, move the automatic transmission
shift selector to the N position and
shift the 4WD shift switch to 2WD

●Before placing the 4WD shift switch in
the 4H position from 2WD or AUTO,
ensure the vehicle speed is less than 62
MPH (100 km/h) . Failure to do so can
damage the 4WD system.
● Never shift the 4WD shift switch be-
tween 4LO and 4H while driving.
● Engine idling speed is high while warm-
ing up the engine. Be especially careful
when starting or driving on slippery sur-
faces with the 4WD shift switch set in
AUTO.
4WD shift indicator light
The 4WD shift indicator light is located in the
vehicle information display.
The light should turn off within 1 second after
turning the ignition switch to the ON position.
While the engine is running, the 4WD shift indi-
cator light will illuminate the position selected by
the 4WD shift switch.
● The 4WD shift indicator light may blink
while shifting from one drive mode to
the other. When the shifting is com-
pleted, the 4WD shift indicator light
will come on. If the indicator light does
not come on immediately, make sure
the area around the vehicle is safe, and drive the vehicle straight, accelerate or
decelerate or move the vehicle in re-
verse, then shift the 4WD shift switch.
● If the 4WD warning light comes on, the
4WD indicator light goes out.
CAUTION
● When the 4WD shift switch is turned to
the AUTO position at low ambient tem-
peratures, the 4WD shift indicator light
may show 4H. If this happens, all four
wheels are driven as torque distribution
is in the 4H position. Be careful as the
vehicle may become difficult to turn.
When the vehicle is driven, the 4WD
shift indicator light should change to
AUTO.
● If the 4WD shift indicator light indica-
tion changes to 2WD when the 4WD
shift switch is shifted to the AUTO or 4H
position at low ambient temperatures,
the 2WD mode may be being engaged
due to malfunctioning drive system. If
the indicator does not return to normal
and the 4WD warning light comes on,
have the system checked by the nearest
INFINITI dealer.

4WD warning light
Warning lightComes on or blinks
when:
Comes on There is a malfunc-
tion in the 4–wheel drive system
Blinks rapidly The transfer case
oil temperature is abnormally high
Blinks slowly The difference in
wheel rotation is large
The 4WD warning light is located in the meter.
The 4WD warning light comes on when the igni-
tion switch is placed in the ON position. It turns
off soon after the engine is started.
If any malfunction occurs in the 4WD system
when the ignition switch is ON, the warning light
will either remain illuminated or blink.
If the 4WD warning light comes on, the 4WD
shift indicator light goes out. High-temperature transfer case oil makes the
warning light blink rapidly (about twice per sec-
ond) . If the warning light blinks rapidly during
operation, stop the vehicle in a safe place imme-
diately. 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) . Change
the 4WD shift switch into 2WD and do not drive
fast.
CAUTION
●
If the warning light comes on or blinks
slowly during operation or rapidly after
stopping the vehicle for a while, have
your vehicle checked by an INFINITI
dealer as soon as possible.

recommended when the 4WD warning
light turns on.
● When the warning light comes on, the
2WD mode may be engaged even if the
4WD shift switch is in AUTO or 4H. Be
especially careful when driving. If corre-
sponding parts are malfunctioning, the
4WD mode will not be engaged even if
the 4WD shift switch is shifted. ●
Do not drive the vehicle in the 4H or 4LO
position on dry hard surface roads. Driv-
ing on dry, hard surfaces in 4H or 4LO
may cause unnecessary noise, tire wear
and increased fuel consumption.
