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:
Page 368 of 578
.On roads where there are multiple
parallel lane markers; lane markers
that are faded or not painted clearly;
yellow painted lane markers; non-stan-
dard lane markers; or lane markers
covered with water, dirt, snow, etc.
. On roads where discontinued lane
markers are still detectable.
. On roads where there are sharp curves.
. On roads where there are sharply
contrasting objects, such as shadows,
snow, water, wheel ruts, seams or lines
remaining after road repairs. (The LDP
system could detect these items as
lane markers.)
. On roads where the traveling lane
merges or separates.
. When the vehicle’s traveling direction
does not align with the lane marker.
. When traveling close to the vehicle in
front of you, which obstructs the lane
camera unit detection range.
. When rain, snow or dirt adheres to the
windshield in front of the lane camera
unit.
. When the headlights are not bright due
to dirt on the lens or if the aiming is not
adjusted properly. .
When strong light enters the lane
camera unit. (For example, the light
directly shines on the front of the
vehicle at sunrise or sunset.)
. When a sudden change in brightness
occurs. (For example, when the vehicle
enters or exits a tunnel or under a
bridge.)
While the LDP system is operating, you
may hear a sound of brake operation. This
is normal and indicates that the LDP
system is operating properly.

LDP system operation
The LDP system provides a lane departure
warning and brake control assistance when
the vehicle is driven at speeds of approxi-
mately 45 MPH (70 km/h) and above.
When the vehicle approaches either the left
or the right side of the traveling lane, a
warning chime will sound and the lane
departure warning light (orange) on the
instrument panel will blink to alert the
driver. Then, the LDP system will automa-
tically apply the brakes for a short period
of time to help assist the driver to return

Detection zone
The radar sensors can detect vehicles on
either side of your vehicle within the
detection zone shown as illustrated. This
detection zone starts from the outside
mirror of your vehicle and extends approxi-
mately 10 ft (3 m) behind the rear bumper,
and approximately 10 ft (3 m) sideways.
The BSW system operates above approxi-
mately 20 MPH (32 km/h). If the radar
sensors detect a vehicle in the detection
zone, the the Blind spot warning indicator
light illuminates. If the driver then acti-
vates the turn signal, a chime will sound
twice and the Blind spot warning indicator
light will flash. The Blind Spot Intervention
TMsystem
operates above approximately 37 MPH
(60 km/h). If the system detects a vehicle
in the detection zone and your vehicle is
approaching the lane marker, the Blind
Spot Intervention
TMsystem provides an
audible warning (three times), flashes the
Blind spot warning indicator light and
slightly applies the brakes for a short
period of time on one side to help return
the vehicle back to the traveling lane. The
Blind Spot Intervention
TMsystem provides
an audible warning and turns on or flashes
the Blind spot warning indicator light even
if the BSW system is off.
WARNING
. The BSW and Blind Spot InterventionTM
systems are not a replacement for proper
driving procedure and are not designed
to prevent contact with vehicles or
objects. When changing lanes, always
use the side and rear mirrors and turn
and look in the direction you will move
to ensure it is safe to change lanes.
Never rely solely on the BSW or Blind
Spot Intervention
TMsystem. .
Using the Blind Spot Intervention
TM
system under some road, lane marker
or weather conditions could lead to
improper system operation. Always rely
on your own steering and braking
operation to avoid accidents.
. The BSW and Blind Spot Intervention
TM
systems may not provide a warning or
brake control for vehicles that pass
through the detection zone quickly.

If the driver activates the turn signal, then
the Blind spot warning indicator light
flashes and a chime will sound twice.
NOTE:
If the driver activates the turn signal
before a vehicle enters the detection zone,
the Blind spot warning indicator light will
flash but no chime will sound when the
other vehicle is detected.
SSD1044
If the Blind Spot InterventionTMsystem is
on and your vehicle is approaching a lane
marker, the Blind spot warning indicator
light flashes and a chime will sound three
times. Then the Blind Spot Intervention
TM
system slightly applies the brakes on one
side to help return the vehicle back to the
center of the driving lane.

5-68Starting and driving
If a vehicle ahead appears during accel-
eration to the set vehicle speed or any time
the ICC system is in operation, the system
controls the distance to that vehicle.
When a vehicle is no longer detected under
approximately 15 MPH (24 km/h), the
system will be cancelled.
SSD1108
When passing another vehicle,the set
vehicle speed indicator will flash when the
vehicle speed exceeds the set speed. The
vehicle detect indicator will turn off when
the area ahead of the vehicle is open.
When the pedal is released, the vehicle will
return to the previously set speed.
Even though your vehicle speed is set in
the ICC system, you can depress the
accelerator pedal when it is necessary to
accelerate your vehicle rapidly.
How to change set vehicle speed
To cancel the preset speed, use any of
these methods: .
Push the CANCEL switch. The set vehicle
speed indicator will go out.
. Tap the brake pedal. The set vehicle
speed indicator will go out.
. Turn the MAIN switch off. Both the MAIN
switch indicator and set vehicle speed
indicator will go out.
To reset at a faster cruising speed, use one
of the following methods:
. Depress the accelerator pedal. When
the vehicle attains the desired speed,
push and release the COAST/SET
switch.
. Push and hold the ACCELERATE/RE-
SUME switch. The set vehicle speed
will increase by approximately 5 MPH
or 5 km/h.
. Push, then quickly release the ACCEL-
ERATE/RESUME switch. Each time you
do this, the set speed will increase by
approximately 1 MPH or 1 km/h.
To reset at a slower cruising speed, use
one of the following methods:
. Lightly tap the brake pedal. When the
vehicle attains the desired speed, push
the COAST/SET switch and release it.
. Push and hold the COAST/SET switch.
The set vehicle speed will decrease by
Page 410 of 578
approximately 5 MPH or 5 km/h.
. Push, then quickly release the COAST/
SET switch. Each time you do this, the
set speed will decrease by approxi-
mately 1 MPH or 1 km/h.
To resume the preset speed, push and
release the ACCELERATE/RESUME switch.
The vehicle will resume the last set
cruising speed when the vehicle speed is
over 20 MPH (32 km/h).
SSD0967
How to change set distance to
vehicle ahead
The distance to the vehicle ahead can be
selected at any time depending on the
traffic conditions.
Each time the DISTANCE switch
*Ais
pushed, the set distance will change to
long, middle, short and back to long again
in that sequence.
Starting and driving5-69

.The distance to the vehicle ahead will
change according to the vehicle speed.
The higher the vehicle speed, the
longer the distance.
. If the engine is stopped, the set
distance becomes “long”. (Each time
the engine is started, the initial setting becomes
“long”.)
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 Intelligent Cruise Control (ICC) system
display. Decelerate by depressing the
brake pedal to maintain a safe vehicle
distance if:
.The chime sounds.
. The vehicle ahead detection and set
distance indicator blink.
The warning chime may not sound 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
. When the vehicle ahead is traveling
faster and the distance between vehi-
cles is increasing
. When a vehicle cuts in near your vehicle
The warning chime will not sound in the
following cases:
. When your vehicle approaches vehicles
that are parked or moving slowly
. When the accelerator pedal is de-
pressed, overriding the system

namic drag..Recirculating the cool air in the cabinwhen the A/C is on reduces cooling
load.
4. Drive at economical speeds and dis- tances.
.Observing the speed limit and not
exceeding 60 MPH (97 km/h) (where
legally allowed) can improve fuel
efficiency due to reduced aerody-
namic drag.
.Maintaining a safe following dis-tance behind other vehicles reduces
unnecessary braking.
.Safely monitoring traffic to antici- pate changes in speed permits
reduced braking and smooth accel-
eration changes.
.Select a gear range suitable to road
conditions.
5. Use cruise control.
.Using cruise control during highway driving helps maintain a steady
speed.
.Cruise control is particularly effec-tive in providing fuel savings when
driving on flat terrains. 6. Plan for the shortest route.
.Utilize a map or navigation system to
determine the best route to save
time.
7. Avoid idling.
.Shutting off your engine when safe for stops exceeding 30-60 seconds
saves fuel and reduces emissions.
8. Buy an automated pass for toll roads.
.Automated passes permit drivers to use special lanes to maintain cruis-
ing speed through the toll and avoid
stopping and starting.
9. Winter warm up.
.Limit idling time to minimize impact to fuel economy.
.Vehicles typically need no more than30 seconds of idling at start-up to
effectively circulate the engine oil
before driving.
.Your vehicle will reach its ideal
operating temperature more quickly
while driving versus idling.
10. Keeping your vehicle cool.
.Park your vehicle in a covered
parking area or in the shade when-
ever possible.
.When entering a hot vehicle, open- ing the windows will help to reduce
the inside temperature faster, result-
ing in reduced demand on your A/C
system.

8-4Maintenance and do-it-yourself
fraying, wear or damage.
Seats:Check seat position controls such as
seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head restraints/headrests
move up and down smoothly and that the
locks (if so equipped) hold securely in all
latched positions.
Steering wheel: Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly
and that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel).
Battery*: Check the fluid level in each cell. It should be between the MAX and MIN
lines. Vehicles operated in high tempera-
tures or under severe condition require
frequent checks of the battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1.
Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
Brake fluid level*: Make sure that the
brake fluid level is between the MAX and
MIN lines on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no belt
is frayed, worn, cracked or oily.
Engine oil level*: Check the level after
parking the vehicle on a level spot and turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
Exhaust system:
Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, im-
mediately have the exhaust system in-
spected by an INFINITI retailer. (See
“Precautions when starting and driving”
in the “5. Starting and driving” section for
exhaust gas (carbon monoxide).)
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use
is normal. If you should notice any leaks or
if gasoline fumes are evident, check for the
cause and have it corrected immediately.
Power steering fluid level* and lines:
Check the level when the fluid is cold,
with the engine off. Check the lines for
proper attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, rot or loose connections.
