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.

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 driving on some roads, such as winding,
hilly, curved, narrow, or roads which are under
construction, the ICC sensor may detect vehicles
in a different lane, or may temporarily not detect a
vehicle traveling ahead. This may cause the ICC
system to decelerate or accelerate the vehicle.
The detection of vehicles can be affected by
vehicle operation (steering maneuver or driving
position in the lane) or vehicle condition.If this
occurs, the ICC system may warn you by
blinking the system indicator and sounding
the chime unexpectedly. You will have to
manually control the proper distance away
from the vehicle traveling ahead. When driving on the freeway at a set speed and
approaching a slower traveling vehicle ahead, the
ICC will adjust the speed to maintain the dis-
tance, selected by the driver, from the vehicle
ahead. If the vehicle ahead changes lanes or exits
the freeway, the ICC system will accelerate and
maintain the speed up to the set speed. Pay
attention to the driving operation to maintain con-
trol of the vehicle as it accelerates to the set
speed.
The vehicle may not maintain the set speed on
winding or hilly roads. If this happens, drive with-
out the ICC system.

NOTE:
The approach warning chime may sound
and the system display may blink when the
ICC sensor detects some reflectors
1
which are fitted on vehicles in other lanes
or on the side of the road. This may cause
the ICC system to decelerate or accelerate
the vehicle. The ICC sensor may detect
these reflectors when the vehicle is driven
on winding roads, hilly roads or when en-
tering or exiting a curve. The ICC sensor
may also detect reflectors on narrow roads
or in road construction zones. In these
cases you will have to manually control the
proper distance ahead of your vehicle.
Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driving
position in the lane) or the traffic condition (for
example, if a vehicle is being driven with some
damage) .
Automatic cancellation
A chime sounds under the following conditions
and the control is automatically canceled.● When the vehicle speed falls below approxi-
mately 20 MPH (32 km/h)
● When the selector lever is shifted to a posi-
tion other than D (Drive) , 4, 3, 2, or 1, includ-
ing the manual shift mode ●
When the wiper is operated
● When the parking brake is applied
● When the VDC is turned off
● When the VDC operates

The power assisted steering uses a hydraulic
pump, driven by the engine, to assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, especially
in sharp turns and at low speeds.
WARNING
If the engine is not running or is turned off
while driving, the power assist for the
steering will not work. Steering will be
harder to operate.The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at 2 wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and stopping dis-
tance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brake pads faster, and reduce gas mileage.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
WARNING
●
While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
● If the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal to
heat up the brakes. Do this until the brakes return
to normal. Avoid driving the vehicle at high
speeds until the brakes function correctly.
Parking brake break-in
Break-in the parking brake shoes whenever the
stopping effect of the parking brake is weakened
or whenever the parking brake shoes and/or
drum/rotors are replaced, in order to assure the
best brake performance.

ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
●The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless
or dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remem-
ber that stopping distances on slippery
surfaces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel or snow covered roads, or if you
are using tire chains. Always maintain a
safe distance from the vehicle in front
of you. Ultimately, the driver is respon-
sible for safety.
● Tire type and condition may also affect
braking effectiveness.
– When replacing tires, install the specified size of tires on all four
wheels. – When installing a spare tire, make
sure that it is the proper size and type
as specified on the Tire and Loading
Information label. See “Tire and
Loading Information label” in the
“Technical and consumer informa-
tion” section of this manual.
– For detailed information, see “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of
this manual.
The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on slip-
pery surfaces.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate to prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h) . The speed varies according to road
conditions.
When the ABS senses that 1 or more wheels are
close to locking up, the actuator rapidly applies
and releases hydraulic pressure. This action is
similar to pumping the brakes very quickly. You
may feel a pulsation in the brake pedal and hear a
noise from under the hood or feel a vibration from
the actuator when it is operating. This is normal
and indicates that the ABS is operating properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may hear
a “clunk” noise and/or feel a pulsation in the brake

WARNING
●The Vehicle Dynamic Control system is
designed to help improve driving stabil-
ity but does not prevent accidents due
to abrupt steering operation at high
speeds or by careless or dangerous
driving techniques. Reduce vehicle
speed and be especially careful when
driving and cornering on slippery sur-
faces and always drive carefully.
● Do not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not INFINITI
approved for your vehicle or are ex-
tremely deteriorated the Vehicle Dy-
namic Control system may not operate
properly. This could adversely affect ve-
hicle handling performance, and the
VDC OFF indicator light may come on.
● If brake related parts such as brake
pads, rotors and calipers are not stan-
dard equipment or are extremely dete-
riorated, the Vehicle Dynamic Control
system may not operate properly and
the Vehicle Dynamic Control off indica-
tor light may come on. ●
When driving on extremely inclined sur-
faces such as higher banked corners,
the Vehicle Dynamic Control system
may not operate properly and the VDC
OFF indicator light may come on. Do
not drive on these types of roads.
● When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the Vehicle Dynamic Control off
indicator light may illuminate. This is
not a malfunction. Restart the engine
after driving onto a stable surface.
● If wheels or tires other than the recom-
mended ones are used, the Vehicle Dy-
namic Control system may not operate
properly and the Vehicle Dynamic Con-
trol off indicator light may come on.
● The Vehicle Dynamic Control system is
not a substitute for winter tires or tire
chains on a snow covered road.
WARNING
● Always turn and look back before back-
ing up. The RSS is not a substitute for
proper backing procedures.
● Read and understand the limitations of
the rear sonar system as contained in
this section. Inclement weather may af-
fect the function of the RSS; this may
include reduced performance or a false
activation.
● This system is not designed to prevent
contact with small or moving objects.

DRAINING OF COOLANT WATER
If the vehicle is to be left outside without anti-
freeze, drain the cooling system, including the
engine block. Refill before operating the vehicle.
For details, see “Changing engine coolant” in the
“Maintenance and do-it-yourself” section of this
manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your ve-
hicle on snowy or icy roads, INFINITI recom-
mends the use of MUD & SNOW or ALL
SEASON TIRES on all four wheels. Please
consult an INFINITI dealer for the tire type,
size, speed rating and availability informa-
tion.
2. For additional traction on icy roads, studded tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow tires. 3. Tire chains may be used. For details see
“Tire chains” in the “Maintenance and do-it-
yourself” section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the vehicle during winter:
● A scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
● A sturdy, flat board to be placed under the
jack to give it firm support.
● A shovel to dig the vehicle out of snowdrifts.
● Extra window washer fluid to refill the reser-
voir tank.
DRIVING ON SNOW OR ICE
WARNING
● Wet ice (32°F, 0°C and freezing rain) ,
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” under
these conditions. Try to avoid driving on
wet ice until the road is salted or
sanded. ●
Whatever the condition, drive with cau-
tion. Accelerate and slow down with
care. If accelerating or downshifting too
fast, the drive wheels will lose even
more traction.
● Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
● Allow greater following distances on
slippery roads.
● Watch for slippery spots (glare ice) .
These may appear on an otherwise
clear road in shaded areas. If a patch of
ice is seen ahead, brake before reach-
ing it. Try not to brake while on the ice,
and avoid any sudden steering
maneuvers.
● Do not use the cruise control on slip-
pery roads.
● Snow can trap dangerous exhaust
gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.
