When the ignition switch is pushed without
depressing the brake pedal, the ignition
switch position will change as follows:
. Push center once to change to ACC.
. Push center two times to change to ON.
. Push center three times to change to
OFF. (No position illuminates.)
. Push center four times to return to ACC.
. Open or close any door to return to
LOCK during the OFF position.
The ignition lock is designed so that the
ignition switch position cannot be switched
to LOCK until the shift lever is moved to the
P (Park) position. When the ignition switch cannot be pushed
toward the LOCK position, proceed as
follows:
1. Move the shift lever into the P (Park)
position.
2. Push the ignition switch to the OFF position. The ignition switch position
indicator will not illuminate.
3. Open the door. The ignition switch will change to the LOCK position.
The shift lever can be moved from the P
(Park) position if the ignition switch is in
the ON position and the brake pedal is
depressed.
If the battery of the vehicle is discharged,
the push-button ignition switch cannot be
turned from the LOCK position.
Some indicators and warnings for opera-
tion are displayed on the dot matrix liquid
crystal display between the speedometer
and tachometer. (See “Dot matrix liquid
crystal display” in the“2. Instruments and
controls” section.)

ENGINE PROTECTION MODE
The engine has an engine protection mode
to reduce the chance of damage if the
coolant temperature becomes too high (for
example, when climbing steep grades in
high temperature with heavy loads, such
as when towing a trailer).
When the engine temperature reaches a
certain level:
.The engine coolant temperature gauge
will move toward the H position.
. Engine power may be reduced.
. The air conditioning cooling function
may be automatically turned OFF for a
short time (the blower will continue to
operate).
Engine power and, under some conditions,
vehicle speed will decrease. Vehicle speed
can be controlled with the accelerator
pedal, but the vehicle may not accelerate
at the desired speed. The transmission will
downshift or upshift as it reaches pre-
scribed shift points. You can also shift
manually.
As driving conditions change and engine
coolant temperature is reduced, vehicle
speed can be increased using the accel-
erator pedal, and air conditioning cooling function will automatically be turned back
ON.
If:
1. The engine coolant temperature is not
reduced.
2. The air conditioning cooling function does not turn back ON.
3. The engine oil pressure warning light
illuminates or engine coolant
temperature gauge does not return to
the normal range from the H position,
this may indicate a malfunction. Move
the vehicle off the road to a safe area
and allow the engine to cool. If after
checking the oil and coolant, the
remains on or engine coolant tempera-
ture does not return to the normal
range, do not continue to drive and
contact an INFINITI retailer.
The Malfunction Indicator Light (MIL)
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 retailer. See “Warning/indicator
lights and audible reminders” in the“2.
Instruments and controls” section.
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 collision. Be
especially careful when driving. If the
vehicle cannot maintain a safe driving
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 over-
heats” in the“6. In case of emergency”
section.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not covered
by warranty. Turn off the engine as soon as
it is safe to do so.

LANE DEPARTURE PREVENTION
(LDP) SYSTEM
Precautions on LDP system
WARNING
.The LDP system 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 vehicle at all
times.
. The LDP system is primarily intended for
use on well-developed freeways or high-
ways. It may not detect the lane markers
in certain roads, weather or driving
conditions.
. Using the LDP system under some
conditions of road, lane marker or
weather, or when you change lanes
without using the lane change signal
could lead to an unexpected system
operation. In such conditions, you need
to correct the vehicle’s direction with
your steering operation to avoid acci-
dents. .
When the LDP system is operating, avoid
excessive or sudden steering maneu-
vers. Otherwise, you could lose control
of the vehicle.
. The LDP system will not operate at
speeds below approximately 45 MPH
(70 km/h) or if it cannot detect lane
markers.
. The LDP system may not function
properly under the following conditions,
and do not use the LDP system:
—During bad weather (rain, fog, snow,
wind, etc.).
—When driving on slippery roads,
such as on ice or snow, etc.
—When driving off-road such as on sand or rock, etc.
—When driving on winding or uneven
roads.
—When there is a lane closure due toroad repairs.
—When driving in a makeshift lane.
—When driving on roads where thelane width is too narrow.
—When driving without normal tireconditions (for example, tire wear, low tire pressure, installation of
spare tire, tire chains, non-standard
wheels).
—When the vehicle is equipped with
non-original brake parts or suspen-
sion parts.
—When towing a trailer or othervehicle.
. If the LDP system malfunctions, it will
cancel automatically. The lane departure
warning light (orange) on the instrument
panel will illuminate.
. If the lane departure warning light
(orange) illuminates, pull off the road
to a safe location and stop the vehicle.
Turn the engine off and restart the
engine. If the warning light (orange)
continues to illuminate, have the LDP
system checked by an INFINITI retailer.
. Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
The functions of the LDP system (warning
and brake control assist) may or may not
operate properly under the following con-
ditions:

will interfere with the chime sound, and
it may not be heard.
. The radar sensors may not be able to
detect and activate Blind Spot Interven-
tion
TM/BSW when certain objects are
present such as:
—Pedestrians, bicycles, animals
—Several types of vehicles such as motorcycles
—Oncoming vehicles
—Vehicles remaining in the detectionzone when you accelerate from a
stop
(See “BSW/Blind Spot Intervention
TM
driving situations” later in this sec-
tion)
—A vehicle merging into an adjacent lane at a speed approximately the same as your vehicle
(See
“BSW/Blind Spot Intervention
TM
driving situations” later in this sec-
tion)
—A vehicle approaching rapidly from behind.
(See “BSW/Blind Spot Intervention
TM
driving situations” later in this sec-
tion)
—A vehicle which your vehicle over-
takes rapidly.
(See “BSW/Blind Spot Intervention
TM
driving situations” later in this sec-
tion)
. Severe weather or road spray conditions
may reduce the ability of the radar to
detect other vehicles.
. The radar sensors detection zone is
designed based on a standard lane
width. When driving in a wider lane,
the radar sensors may not detect vehi-
cles in an adjacent lane. When driving in
a narrow lane, the radar sensors may
detect vehicles driving two lanes away.
. The radar sensors are designed to ignore
most stationary objects, however ob-
jects such as guardrails, walls, foliage

NOTE:
.In the case of several vehicles ap-
proaching in a row or from the opposite
direction, a chime may not be output to
the BCI system after the first vehicle
passes the sensors.
. When the parking sensor of the Around
View Monitor sounds a tone, the BCI
system does not chime a sound (single
beep).
If the detected vehicle approaches closer
and your vehicle is backing up toward the
detected vehicle, the system chimes a
sound (three times) and a red rectangular
frame

it is on flat ground. When on a steep
slope the system may not function
properly.
. Do not use the BCI systems under the
following conditions because the system
may not function properly.
—When driving with a tire that is not
within normal tire conditions (for
example, tire wear, low tire pressure,
installation of spare tire, tire chains,
non-standard wheels).
—When the vehicle is equipped with
non-original brake parts or suspen-
sion parts.

under the following conditions. To avoid
accidents, never use the ICC system
under the following conditions:
—On roads where the traffic is heavyor there are sharp curves
—On slippery road surfaces such as
on ice or snow, etc.
—On off-road surfaces such as onsand or rock, etc.
—During bad weather (rain, fog, snow,
etc.)
—When the windshield wipers areoperating at high speed. The system
may cancel when the wipers are set
to the AUTO position.
—When strong light (for example, at sunrise or sunset) is directly shining
on the front of the vehicle
—When rain, snow or dirt adhere tothe system sensor
—On steep downhill roads (the vehi-cle may go beyond the set vehicle
speed and frequent braking may
result in overheating the brakes)
—On repeated uphill and downhillroads
—When traffic conditions make itdifficult to keep a proper distance
between vehicles because of fre-
quent acceleration or deceleration
—When towing a trailer or othervehicle
. In some road or traffic conditions, a
vehicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. You may need to
control the distance from other vehicles
using the accelerator pedal. Always stay
alert and avoid using the ICC system
when it is not recommended in this
section.

VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE OPERATION
Always pay attention to the operation of
the vehicle and be ready to manually
control the proper following distance. The
vehicle-to-vehicle distance control mode of
the Intelligent Cruise Control (ICC) system
may not be able to maintain the selected
distance between vehicles (following dis-
tance) or selected vehicle speed under
some circumstances.
The vehicle-to-vehicle distance control
mode uses a sensor
*Alocated on the
front of the vehicle to detect vehicles
Starting and driving5-59

5-60Starting and driving
traveling ahead. The sensor generally
detects the signals returned from the
reflectors on a vehicle ahead. Therefore, if
the sensor cannot detect the reflector on
the vehicle ahead, the ICC system may not
maintain the selected distance.
The following are some conditions in which
the sensor cannot detect the signals:
.When the reflector of the vehicle ahead
is positioned high on the vehicle
(trailer, etc.)
. When the reflector on the vehicle ahead
is missing, damaged or covered
. When the reflector of the vehicle ahead
is covered with dirt, snow and road
spray
. When the snow or road spray from
traveling vehicles reduces the sensor’s
visibility
. When dense exhaust or other smoke
(black smoke) from vehicles reduces
the sensor’s visibility
. When excessively heavy baggage is
loaded in the rear seat or the luggage
area of your vehicle
. When your vehicle is towing a trailer,
etc.
The ICC system is designed to automati- cally check the sensor’s operation within
the limitation of the system. When the
sensor is covered with dirt or obstructs, the
system will automatically be canceled. If
the sensor is covered with ice, a transpar-
ent or translucent vinyl bag, etc., the ICC
system may not detect them. In these
instances, the vehicle-to-vehicle distance
control mode may not cancel and may not
be able to maintain the selected following
distance from the vehicle ahead. Be sure to
check and clean the sensor regularly.
The vehicle-to-vehicle distance control
mode is designed to maintain a selected
distance and reduce the speed to match
the slower vehicle ahead; the system will
decelerate the vehicle as necessary, and if
the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill. How-
ever, the ICC system can only apply up to
25% of the vehicles total braking power.
This system should only be used when
traffic conditions allow vehicle speeds to
remain fairly constant or when vehicle
speeds change gradually. If a vehicle
moves into the traveling lane ahead or if
a vehicle traveling ahead rapidly decele-
rates, the distance between vehicles may
become closer because the ICC system
cannot decelerate the vehicle quickly en-
ough. If this occurs, the ICC system will
sound a warning chime and blink the
system display to notify the driver to take
necessary action.
The system will cancel and a warning
chime will sound if the speed falls below
approximately 15 MPH (24 km/h) and a
vehicle is not detected ahead. The system
will also disengage when the vehicle goes
above the maximum set speed.
See
“Approach warning” later in this
section.
The following items are controlled in the
vehicle-to-vehicle distance control mode:
. When there are no vehicles traveling
ahead, the vehicle-to-vehicle distance
control mode maintains the speed set
by the driver. The set speed range is
between approximately 20 and 90 MPH
(32 and 144 km/h).
. When there is a vehicle traveling ahead,
the vehicle-to-vehicle distance control
mode adjusts the speed to maintain the
distance, selected by driver, from the
vehicle ahead. The adjusting speed
range is up to the set speed. If the
vehicle ahead comes to a stop, the
vehicle decelerates to a standstill with-

The detection range of the sensor is
approximately 390 ft (120 m) ahead.
WARNING
.This system is only an aid to assist the
driver and is not a collision warning or
avoidance device. It is the driver’ s
responsibility to stay alert, drive safely
and be in control of the vehicle at all
times.
. This system will not adapt automatically
to road conditions. Do not use the
system on roads with sharp curves, or
on icy roads, in heavy rain or in fog.
The distance sensor will not detect the
following objects:
.Stationary and slow moving vehicles
. Pedestrians or objects in the roadway
. Oncoming vehicles in the same lane
. Motorcycles traveling offset in the travel
lane
WARNING
. As there is a performance limit to the
distance control function, never rely
solely on the Distance Control Assist
system. This system does not correct
careless, inattentive or absent-minded
driving, or overcome poor visibility in
rain, fog, or other bad weather. Decele-
rate the vehicle speed by depressing the
brake pedal, depending on the distance
to the vehicle ahead and the surround-
ing circumstances in order to maintain a
safe distance between vehicles.
. The system may not function properly
under the following conditions. To avoid
accidents, never use the Distance Con-
trol Assist system under the following
conditions:
—On roads with sharp curves
—On slippery road surfaces such as
on ice or snow, etc.
—On off-road surfaces such as onsand or rock, etc.
—During bad weather (rain, fog, snow,etc.)
—When strong light (for example, atsunrise or sunset) is directly shining
on the front of the vehicle
—When rain, snow or dirt adhere tothe system sensor
—On steep downhill roads (frequent
braking may result in overheating
the brakes)
—On repeated uphill and downhillroads
—When towing a trailer or othervehicle
. In some road or traffic conditions, a
vehicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. You may need to
control the distance from other vehicles
using the accelerator pedal. Always stay
alert and avoid using the DCA system
when it is not recommended in this
section.
Starting and driving5-79

The FCW system uses the distance sensor
*Alocated below the front bumper to
measure the distance to the vehicle ahead.
When the system judges that your vehicle
is getting close to the vehicle ahead in the
travel lane, the vehicle ahead detection
indicator blinks and a warning chime
sounds.
PRECAUTIONS ON FCW SYSTEM
WARNING
. The FCW system is intended to warn you
before a collision but will not avoid a
collision. It is the driver’s responsibility
to stay alert, drive safely and be in
control of the vehicle at all times.
. As there is a performance limit, the
system may not provide a warning in
certain conditions.
. The system will not detect the following
objects:
—Pedestrians, animals or obstacles in
the roadway
—Oncoming vehicles in the same lane
. The system will not detect another
vehicle under the following conditions:
—When the sensor gets dirty and it is
impossible to detect the distance
from the vehicle ahead.
—When driving into a strong light (forexample, sunlight)
. The sensor generally detects the signals
returned from the reflectors on a vehicle
ahead. Therefore, the system may not
function properly under the following
conditions:
—When the reflectors of the vehicle
ahead are positioned high or close to
each other (including a small vehicle
such as motorcycles).
—When the sensor gets dirty or it isimpossible to detect the distance
from the vehicle ahead.
—When the reflectors on the vehicle
ahead are missing, damaged or
covered.
—When the reflectors of the vehicleahead are covered with dirt, snow or
road spray.
—When visibility is low (such as rain,fog, snow, etc.).
—When snow or road spray fromtraveling vehicles is splashed.
—When dense exhaust or other smoke (black smoke) from vehicles reduces
the visibility of the sensor.
—When excessively heavy baggage is
loaded in the rear seat or the
luggage room of your vehicle.
—When abruptly accelerating or de-celerating.
—On a steep downhill slope or onroads with sharp curves.
—When there is a highly reflectiveobject near the vehicle ahead (for
example, being very close to another
vehicle, signboard, etc.).
—When you are towing a trailer.
. Depending on certain road conditions
(curved or beginning of a curve), vehicle
conditions (steering position or vehicle
position), or the preceding vehicle’ s
conditions (position in lane, etc.), the
system may not function properly. The
system may detect highly reflective
objects such as reflectors, signs, white
markers, and other stationary objects on
the road or near the traveling lane and
