freeway.
•The system detects solid lane markings.
The warning vibration occurs later if:
•The road has narrow lanes.
•You cut across a corner on a bend.
LDW SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for the
LDW system. Failure to operate the vehicle in
accordance with these system limitations
could result in serious injury or death.
•This system is only a warning device to in-
form the driver of a potential unintended
lane departure. It will not steer the vehicle
or prevent loss of control. It is the driver’s
responsibility to stay alert, drive safely,
keep the vehicle in the traveling lane, and
be in control of the vehicle at all times.

WARNING
•If you fail to adapt your driving style, cruise
control can neither reduce the risk of an
accident nor override the laws of physics.
Cruise control cannot take into account
road, weather or traffic conditions. Cruise
control is only an aid. You are responsible
for the distance to the vehicle in front, for
vehicle speed, for braking in good time, and
for staying in lane.
•Always observe the posted speed limits and
do not set the speed over them.
•Do not use the cruise control when driving
under the following conditions. Doing so
could cause a loss of vehicle control and
result in an accident.– When it is not possible to keep the ve-
hicle at a constant speed
– When driving in heavy traffic
– When driving in traffic that varies speed
– When driving in windy areas
– When driving on winding or hilly roads
– When driving on slippery (rain, snow,
ice, etc.) roads
CRUISE CONTROL OPERATIONS
1Store the current speed or a higher speed
2Store the current speed, or if a speed has
previously been stored, call up the last
stored speed.
3Store the current speed or a lower speed
4Deactivate the cruise control system
When you activate cruise control, the stored
speed is shown in the vehicle information dis-
play for five seconds.
Activation conditions
To activate cruise control, all of the following
activation conditions must be fulfilled:
•The electric parking brake must be released.
•You are driving faster than 20 MPH (30
km/h).
•VDC must be switched on, but not interven-
ing.
Storing, maintaining and calling up a
speed
Storing and maintaining the current speed:
You can store the current speed if you are
driving faster than 20 MPH (30 km/h):
1. Accelerate the vehicle to the desired speed.
2. Briefly press the cruise controller lever up
1or down3.
3. Remove your foot from the accelerator pedal.
Cruise control is activated. The vehicle auto-
matically maintains the speed.
NOTE
Cruise control may be unable to maintain the
stored speed on uphill gradients. The stored
speed is resumed when the gradient evens out.
Cruise control maintains the stored speed on
downhill gradients by automatically braking the
vehicle.
NSD618A
Starting and driving5-45

Storing the current speed or calling up the last
stored speed:
WARNING
If you call up a stored speed and this is differ-
ent from the current speed, the vehicle accel-
erates or brakes. If you do not know what the
stored speed is, the vehicle may accelerate or
brake unexpectedly. There is a risk of an acci-
dent.
Take the traffic conditions into account before
calling up the stored speed. If you do not know
what the stored speed is, store the desired
speed again.
1. Briefly pull the cruise control lever towards you
2.
2. Remove your foot from the accelerator pedal. The first time cruise control is acti-
vated, it stores the current speed or if a
speed has previously been stored, it regu-
lates the speed of the vehicle to the previ-
ously stored speed.
Setting a speed
Bear in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the set speed.
1. Press the cruise control lever up
1for a
higher speed or down
3for a lower speed.
2. Keep the cruise control lever pressed until the desired speed is reached.
3. Release the cruise control lever, The new speed is stored.
4. To adjust the set speed in 1 MPH (1 km/h) increments: briefly press the cruise control
lever up
1or down3to the pressure
point. The last stored speed increases or
decreases in 1 MPH (1 km/h) increments.
5. To adjust the set speed in 10 MPH (10 km/h) increments: briefly press the cruise control
lever up
1or down3beyond the pressure
point. The last stored speed increases or
decreases in 10 MPH (10 km/h) increments.
NOTE
Cruise control is not deactivated if you depress
the accelerator pedal. For example, if you accel-
erate briefly to overtake, cruise control adjusts
the vehicle’s speed to the last speed stored after
you have finished overtaking.
Deactivating cruise control
There are several ways to deactivate cruise
control:
•Briefly press the cruise control lever forward
4.
or
•Brake.
Cruise control is automatically deactivated if:
•The vehicle is secured with the electric park-
ing brake.
•You are driving at less than 20 MPH (30
km/h).
•VDC intervenes or you deactivate VDC.
If cruise control is deactivated, you will hear a
warning tone. You will see the [Cruise Control
Off] message in the vehicle information display
for approximately five seconds.
NOTE
The last speed stored is cleared when you switch
off the engine.
5-46Starting and driving

Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that vehicle
or if another vehicle cuts in, the system warns
the driver with the chime and distance warning
light. Decelerate by depressing the brake pedal
to maintain a safe vehicle distance if:
•The chime sounds.
•The distance warning light is illuminated.
The warning chime may not sound and the
distance warning light may not illuminate in
some cases when there is a short distance
between vehicles. Some examples are:
•When the vehicles are traveling at the same
speed and the distance between vehicles is
not changing. In this case, the distance
warning light will be on.
•When the vehicle ahead is traveling faster
and the distance between vehicles is increas-
ing.
•When a vehicle cuts in near your vehicle
•The warning chime will not sound and the
distance warning light will not illuminate
when: – The vehicle approaches other vehicles that are parked or moving slowly. – The accelerator pedal is depressed, over-
riding the system.
Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driving
position in the lane) or traffic or vehicle condi-
tion (for example, if a vehicle is being driven
with some damage).
Automatic cancellation
A chime sounds and the message [ICC off] is
displayed in the vehicle information display for
5 seconds under the following conditions and
the control is automatically canceled.
•The electric parking brake is applied.
•The VDC intervenes or the VDC is deacti-
vated.
•The P (Park), R (Reverse) or N (Neutral)
position is engaged.
•The cruise control lever is pulled in order to
pull away but the front passenger door or
one of the rear doors is open.
•The vehicle is skidding or a wheel slips.
•Active Park Assist is activated.
ICC LIMITATIONS
WARNING
Listed below are the system limitations for the
ICC system. Failure to operate the vehicle in
accordance with these system limitations
could result in serious injury or death.
•This system is only an aid to assist the
driver and is not a collision warning or
avoidance device. It is the driver’s responsi-
bility to stay alert, drive safely and be in
control of the vehicle at all times.
•The system is primarily intended for use on
straight, dry, open roads with light traffic. It
is not advisable to use the system in city
traffic or congested areas.
•This system will not adapt automatically to
road conditions. This system should be
used in evenly flowing traffic. Do not use the
system on roads with sharp curves, or on icy
roads, in heavy rain or in fog.
•As there is a performance limit to the dis-
tance control function, never rely solely on
the ICC system. This system does not cor-
rect careless, inattentive or absent-minded
driving, or overcome poor visibility in rain,
fog, or other bad weather. Decelerate the
vehicle speed by depressing the brake

merge into traffic on your own. The parking
sensor system is still available. You can take
over the steering before the vehicle has exited
the parking space completely. This is useful, for
example when you recognise that it is already
possible to pull out of the parking space.
CANCELING IPA
Stop the movement of the steering wheel or
steer yourself. IPA will be immediately can-
celed. The [Park Assist canceled] message ap-
pears in the vehicle information display.
or
Press the parking sensor system OFF switch.
The parking sensor system is switched off and
IPA is immediately canceled The [Park Assist
canceled] message appears in the vehicle infor-
mation display.IPA is canceled automatically if:
•The electric parking brake is applied
•Parking using IPA is no longer possible
•You are driving faster than 5 MPH (10 km/h)
•A wheel spins and VDC intervenes or fails.
Thewarning light lights up in the
combination meter.
A warning tone sounds. The parking symbol
disappears and the vehicle information display
shows the [Park Assist canceled] message.
When IPA is canceled, you must steer again
yourself.
WARNING
•The parking sensor system is a convenience
but it is not a substitute for proper parking.
Always look around and check that it is safe
to do so before parking. Always move
slowly.
•Read and understand the limitations of the
parking sensor system as contained in this
section. Inclement weather may affect the
function of the parking sensor system; this
may include reduced performance or a false
activation.
•This system is not designed to prevent con-
tact with small or moving objects.
•The system is designed as an aid to the
driver in detecting large stationary objects
to help avoid damaging the vehicle. The
system will not detect small objects below
the bumper, and may not detect objects that
are too close to the bumper or on the
ground.
•If your vehicle sustains damage to the bum-
per fascia, leaving it misaligned or bent, the
sensing zone may be altered causing inac-
curate measurement of obstacles or false
alarms.

equipped with 4WD before it is placed on a
dynamometer. Using the wrong test equip-
ment may result in drivetrain damage or un-
expected vehicle movement which could re-
sult in serious vehicle damage or personal
injury.
•When a wheel is off the ground due to an
uneven surface, do not spin the wheel
excessively.
CAUTION
Never tow the vehicle with one axle raised. This
may damage the differential. Damage of this
sort is not covered by the warranty. All wheels
must be fully raised (seeFour-Wheel Drive
(4WD) models in the6. In case of emergency
section)
4WD, together with VDC, improves the traction
of your vehicle whenever a drive wheel spins
due to insufficient grip.
If you fail to adapt your driving style, 4WD can
neither reduce the risk of an accident nor
override the laws of physics. 4WD cannot take
account of road, weather, and traffic conditions.
4WD is only an aid. You are responsible for the
distance to the vehicle in front, for vehicle speed, for braking in good time, and for staying
in lane.
If a drive wheel spins due to insufficient grip
•When pulling away, only depress the accel-
erator pedal as far as is necessary.
•Accelerate less when driving.
NOTE
In wintry driving conditions, the maximum effec-
tiveness of 4WD can only be achieved if you use
winter tires (M+S tires), with snow chains if nec-
essary.
WARNING
•Do not stop or park the vehicle over flam-
mable materials such as dry grass, waste
paper or rags. They may ignite and cause a
fire.
•Safe parking procedures require that both
the parking brake be applied and the P
(Park) position engaged. Failure to do so
could cause the vehicle to move unexpect-
edly or roll away and result in an accident.
•When parking the vehicle, make sure the P
(Park) position is engaged. The shift lever
cannot be moved out of the P (Park) position
without depressing the brake pedal.
•Never leave the engine running while the
vehicle is unattended.
•To help avoid risk of injury or death through
unintended operation of the vehicle and/or
its systems, do not leave children, people
who require the assistance of others, or
pets unattended in your vehicle. Addition-
ally, the temperature inside a closed vehicle
on a warm day can quickly become high
enough to cause a significant risk of injury
or death to people and pets.
PARKING
5-84Starting and driving

The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and
vehicle motion. Under certain driving condi-
tions, the VDC system helps to perform the
following functions.
•Controls brake pressure to reduce wheel slip
on one slipping drive wheel so power is
transferred to a non slipping drive wheel on
the same axle.
•Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function).
•Controls brake pressure at individual wheels
and engine output to help the driver maintain
control of the vehicle in the following condi-
tions:– understeer (vehicle tends to not follow the steered path despite increased steering
input)
– oversteer (vehicle tends to spin due to certain road or driving conditions).
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss
of vehicle control in all driving situations. When the VDC system operates, the VDC warn-
ing light in the instrument panel flashes so note
the following:
•The road may be slippery or the system may
determine some action is required to help
keep the vehicle on the steered path.
•You may feel a pulsation in the brake pedal
and hear a noise or vibration from under the
hood. This is normal and indicates that the
VDC system is working properly.
•Adjust your speed and driving to the road
conditions.
See Vehicle Dynamic Control (VDC) warning
light in the 2. Instruments and controls sec-
tion.
If a malfunction occurs in the system, the VDC
warning light
illuminates in the instrument
panel. The VDC system automatically turns off.
WARNING
•The VDC system is designed to help the
driver maintain stability but does not pre-
vent accidents due to abrupt steering opera-
tion at high speeds or by careless or danger-
ous driving techniques. Reduce vehicle
speed and be especially careful when driv- ing and cornering on slippery surfaces and
always drive carefully.
•Do not modify the vehicle’s suspension. If
suspension parts such as shock absorbers,
struts, springs, stabilizer bars, bushings
and wheels are not INFINITI recommended
for your vehicle or are extremely deterio-
rated, the VDC system may not operate
properly. This could adversely affect vehicle
handling performance, and the VDC warning
light
may illuminate.
•If brake related parts such as brake pads,
rotors and calipers are not INFINITI recom-
mended or are extremely deteriorated, the
VDC system may not operate properly and
the VDC warning light
may illuminate.
•If engine control related parts are not
INFINITI recommended or are extremely de-
teriorated, the VDC warning light
may
illuminate.
•When driving on extremely inclined sur-
faces such as higher banked corners, the
VDC system may not operate properly and
the VDC warning light
may illuminate.
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 (VDC)
SYSTEM
5-90Starting and driving

VDC warning lightmay illuminate. This
is not a malfunction. Restart the engine af-
ter driving onto a stable surface.
•If wheels or tires other than the INFINITI
recommended ones are used, the VDC sys-
tem may not operate properly and the VDC
warning light
may illuminate.
•The VDC system is not a substitute for win-
ter tires or tire chains on a snow covered
road.
•If VDC is malfunctioning, VDC is unable to
stabilize the vehicle. In addition, other driv-
ing safety systems are switched off. This
increases the risk of skidding and an acci-
dent. Drive on carefully. Have VDC checked.
It is recommended you visit an INFINITI re-
tailer for this service.
CAUTION
•When VDC is deactivated, theVDC
OFF warning light lights up continuously.
•If both thewarning light andwarning light are lit continuously, VDC is
not available due to a malfunction.
TRACTION CONTROL SYSTEM (TCS)
The Traction Control System (TCS) is part of
VDC..
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is trans-
ferred to the wheel or wheels with traction.
Traction control remains active if you deactivate
VDC.
CHARACTERISTICS OF VDC
If theVDC warning light goes out before
beginning the journey, VDC is automatically
active.
If VDC intervenes, the
VDC warning lamp
flashes in the combination meter.
If VDC intervenes:
•Do not deactivate VDC under any circum-
stances.
•When pulling away, only depress the accel-
erator pedal as far as is necessary.
•Adapt your driving style to suit the prevailing
road and weather conditions.
Deactivating/activating VDC
WARNING
If you deactivate VDC, VDC no longer stabilizes
the vehicle. There is an increased risk of skid-
ding and an accident.
Only deactivate VDC in the situations de-
scribed in the following section.
You can select between the following statuses
of VDC:
•VDC is activated.
•VDC is deactivated.
It may be best to deactivate VDC in the follow-
ing situations:
•When using snow chains.
•In deep snow.
•On sand or gravel.
NOTE
Activate VDC as soon as the situations described
above no longer apply. VDC will otherwise not be
Starting and driving5-91

able to stabilize the vehicle if the vehicle starts
to skid or a wheel starts to spin.
You can activate/deactivate VDC using the ve-
hicle information display. To activate/
deactivate VDC:
1. Start the engine
2. Press the
orbutton on the
steering wheel to select the [DriveAssist]
menu in the vehicle information display.
3. Press the
orbutton to select
VDC.
4. Press the <OK>button on the steering wheel.
The current selection is displayed.
5. To activate/deactivate: press the <OK>but-
ton again.
VDC is deactivated if the
warning light
in the combination meter lights up continu-
ously when the engine is running.
Characteristics when VDC is deactivated
:
If VDC is deactivated and one or more wheels
start to spin, theVDC warning lamp
flashes in the combination meter. In such situ-
ations, VDC will not stabilize the vehicle. If you deactivate VDC:
•VDC no longer intervenes in understeer or
oversteer situations.
•Engine torque is no longer limited and the
drive wheels are able to spin.
The spinning of the wheels results in a
cutting action, so the tires cut through the
loose surface until the hit solid ground,
giving better traction.
•Traction control is still activated.
•VDC still provides support when you brake.
EBD (ELECTRONIC BRAKE FORCE
DISTRIBUTION)
EBD monitors and controls the brake pressure
on the rear wheels to help improve handling
during braking.
WARNING
If EBD is malfunctioning, the EBD [Inoperative
See Operator’s Manual] warning is displayed
in the vehicle information display. The
VDC warning lamp may also light up.
If EBD is malfunctioning as a result of a VDC
malfunction, the rear wheels can lock, e.g. un-
der full braking. This increases the risk of skid-
ding and an accident.You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked. It is recommended
you see an INFINITI retailer.
STEER CONTROL
STEER CONTROL helps you by transmitting a
noticeable steering force to the steering wheel
in the direction required for vehicle stabilisa-
tion.
This steering support is provided in particular if:
•Both right wheels or both left wheels are on
a wet or slippery road surface when you
brake.
•The vehicle starts to skid.
WARNING
No steering support is provided from STEER
CONTROL, if:
•VDC is malfunctioning.
•The steering is faulty.
Power steering will, however, continue to
function.
5-92Starting and driving

WARNING
•Never rely solely on the Hill Start Assist
(HSA) system to prevent the vehicle from
moving backward on a hill. Always drive
carefully and attentively. Depress the brake
pedal when the vehicle is stopped on a
steep hill. Be especially careful when
stopped on a hill on frozen or muddy roads.
Failure to prevent the vehicle from rolling
backwards may result in a loss of control of
the vehicle and possible serious injury or
death.
•The Hill Start Assist system is not designed
to hold the vehicle at a standstill on a hill.
Depress the brake pedal when the vehicle is
stopped on a steep hill. Failure to do so may
cause the vehicle to roll backwards and may
result in a collision or serious personal in-
jury.
•The Hill Start Assist system may not prevent
the vehicle from rolling backwards on a hill
under all load or road conditions. Always be
prepared to depress the brake pedal to pre-
vent the vehicle from rolling backwards.
Failure to do so may result in a collision or
serious personal injury.
•After a short time, hill start assist will no
longer brake your vehicle and it could rollaway There is a risk of an accident and in-
jury. Therefore, quickly move your foot from
the brake pedal to the accelerator pedal.
Never leave the vehicle when it is held by
hill start assist.
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient. It
holds the vehicle for a short time after you have
removed your foot from the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and
depress it before the vehicle begins to roll.
Hill start assist is not active if
•You are pulling away on a level road or a
downhill gradient.
•On vehicles with automatic transmission, the
transmission is in position N.
•The electric parking brake is applied.
•VDC is malfunctioning.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the
key hole, or use the INFINITI Intelligent Key.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C), check
the antifreeze to assure proper winter protec-
tion. For additional information, see Engine
cooling system in the8. Do-it-yourself sec-
tion.
BATTERY
If the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For details, see
Battery in the8. Do-it-yourself section of this
