●If at all possible, avoid sharp turning
maneuvers, particularly at high speeds.
Your INFINITI four-wheel drive vehicle
has a higher center of gravity than a
passenger car. The vehicle is not de-
signed for cornering at the same
speeds as passenger cars. Failure to
operate this vehicle correctly could re-
sult in loss of control and/or a rollover
accident.
● 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.
● Be sure to check the brakes immedi-
ately after driving in mud or water. See
“Brake system” later in this section for
“Wet brakes”.
● Avoid parking your vehicle on steep
hills. If you get out of the vehicle and it
rolls forward, backward or sideways,
you could be injured. ●
Whenever you drive off-road through
sand, mud or water as deep as the
wheel hub, more frequent maintenance
may be required. See “Periodic mainte-
nance” in the “INFINITI Service and
Maintenance Guide.”WARNING
● Never remove the key or turn the igni-
tion switch to the LOCK position 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 or personal
injury.
● Never turn the ignition switch to the
LOCK position while driving. The steer-
ing wheel will lock. This may cause the
driver to lose control of the vehicle and
could result in serious vehicle damage
or personal injury.

INFINITI INTELLIGENT KEY™
SYSTEM
The ignition lock is designed so that the ignition
switch cannot be placed in the LOCK position
until the shift selector is moved to the P (Park)
position.
When turning the ignition switch, make sure the
shift selector is in the P (Park) position.
If the shift selector is not returned to the P (Park)
position, the ignition switch cannot be moved
toward LOCK.When the ignition switch cannot be turned to-
ward the LOCK position when the Intelligent Key
is in range, proceed as follows:
1. Move the shift selector into the P (Park) position.
2. Turn the ignition switch slightly in the ON direction.
3. Turn the ignition switch toward the LOCK position.
The shift selector can be moved from the P
(Park) position if the ignition switch is in
the ON position and the foot brake pedal is
depressed.
There is an OFF position in between LOCK and
ACC, although it does not show on the lock
cylinder. When the ignition switch 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 counterclock-
wise from the straight up position.
To lock the steering wheel, turn the ignition
switch to the LOCK position. To unlock the
steering wheel, push the ignition switch in
and turn it gently while rotating the steer-
ing 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.
IGNITION SWITCH POSITIONS
Push in the ignition switch to theBposition
when you turn it.

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.

Follow these procedures for maximum vehicle
performance and driving enjoyment.
Starting the vehicle
1. After starting the engine, fully depress thefoot brake pedal before moving the shift
selector out of the P (Park) position.
2. Keep the foot brake pedal depressed and move the shift selector into a driving gear.
3. Release the foot brake, then gradually start the vehicle in motion.
The automatic transmission is designed so
the foot brake pedal MUST be depressed
before shifting from P (Park) to any drive
position while the ignition switch is in the
ON position.
The shift selector cannot be moved out of P
(Park) and into any of the other gear posi-
tions if the ignition switch is placed in the

Shifting
After starting the engine, fully depress the brake
pedal and move the shift selector out of the P
(Park) position.
WARNING
Apply the parking brake if the shift selec-
tor 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.
If the ignition switch is placed in the OFF or ACC
position for any reason while the vehicle is in N
(Neutral) , or any D (Drive) position, the ignition
switch cannot be turned to the LOCK position.
Move the shift selector to the P (Park) position,
then the ignition switch can be turned to LOCK.
P (Park):
CAUTION
To prevent transmission damage, use the
P (Park) or R (Reverse) position only when
the vehicle is completely stopped.
Use the P (Park) shift selector position when the
vehicle is parked or when starting the engine.
Make sure the vehicle is completely stopped.
The brake pedal should be depressed to
move the shift selector from N (Neutral) or
any drive position to P (Park) . Apply the
parking brake. When parking on a hill, apply the
parking brake first, then move the shift selector
into the P (Park) position.

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.

When the vehicle is stuck,● Set the 4WD shift switch to 4H or 4LO.
● If it is difficult to free the vehicle, repeat
forward and backward movement to in-
crease the movement.
● If the vehicle is stuck deep in mud, place
stones or wooden blocks under the tires.
Then try the recovery procedures above. Tire
chains may be effective.
CAUTION
● Do not spin the tires excessively. Tires
will sink deep into the mud, making it
difficult to free the vehicle.
● Avoid shifting gears with the engine
running at high speeds as this may
cause malfunction.
4WD shift switch operations
● Shift the 4WD shift switch to either the
2WD, AUTO, 4H or 4LO position, depend-
ing on driving conditions.
● With the switch set to the AUTO position,
distribution of torque to the front and rear
wheels changes automatically, depending
on road conditions encountered [ratio; 0 :
100 (2WD) →50 : 50 (4WD)]. This results
in improved driving stability. ●
If the 4WD shift switch is operated
while making a turn, accelerating or
decelerating or if the ignition switch is
turned off while in the AUTO, 4H or
4LO, you may feel a jolt. This is not
abnormal.
● When the vehicle is stopped after mak-
ing a turn, you may feel a slight jolt
after the shift selector is shifted to N or
P. This occurs because the transfer
clutch is released and not because of a
malfunction.
CAUTION
● When driving straight, shift the 4WD
shift switch to the 2WD, AUTO or 4H
position. Do not move the 4WD shift
switch when making a turn or reversing.
● Do not shift the 4WD shift switch while
driving on steep downhill grades. Use
the engine brake and low automatic
transmission gears (D1 or D2) for en-
gine braking.
● Do not operate the 4WD shift switch
with the rear wheels spinning.
