FEB WITH PEDESTRIAN
DETECTION SYSTEM
LIMITATIONS
WARNING
Listed below are the system limitations for
the FEB with Pedestrian Detection system.
Failure to operate the vehicle in accor-
dance with these system limitations could
result in serious injury or death.
• The FEB with Pedestrian Detection sys-
tem cannot detect all vehicles or pedes-
trians under all conditions.
• The FEB with Pedestrian Detection sys-
tem does not detect the following:
–
Pedestrians that are small (for ex-
ample, children), in a sitting posi-
tion, operating toys/skateboards, on
scooters or in wheelchairs, or not in an
upright standing or walking position.
– Animals of any size.
– Obstacles (for examples, cargo or de- bris) on the roadway or roadside.
– Oncoming or crossing vehicles.
– Vehicles where the tires are difficult to see or the shape of the rear of the
vehicle is unclear or obstructed.
– Parked vehicles. •
The FEB with Pedestrian Detection sys-
tem has some performance limitations.
– If a stationary vehicle is in the vehi- cle’s path, the FEB with Pedestrian
Detection system will not function
when the vehicle approaches the sta-
tionary vehicle at speeds over ap-
proximately 50 mph (80 km/h).
– Pedestrian detection will not func- tion when the vehicle is driven at
speeds over approximately 37 mph
(60 km/h) or below approximately
6 mph (10km/h).
• For pedestrians, the FEB with Pedes-
trian Detection system will not issue the
first warning.
• The FEB with Pedestrian Detection sys-
tem may not function properly or detect
a vehicle or pedestrian ahead in the fol-
lowing conditions:
– In poor visibility conditions (such as rain, snow, fog, dust storms, sand
storms, smoke, and road spray from
other vehicles).
– If dirt, ice, snow, fog or other material is covering the radar sensor area or
camera area of windshield. – If strong light (for example, sunlight
or high beams) enters the front cam-
era or a sudden change in brightness
occurs (for example, entering a tun-
nel or driving in lightning).
– In dark or dimly lit conditions, such as at night or in tunnels, including cases
where your vehicle’s headlights are
off or dim, or the tail lights of the
vehicle ahead are off.
– When the direction of the camera is misaligned.
– When driving on a steep downhill slope, on roads with sharp curves,
and/or bumpy or dirt roads.
– If there is interference by other radar sources.
– When your vehicle’s position or movement is changed quickly or sig-
nificantly (for example, lane change,
turning vehicle, abrupt steering, sud-
den acceleration or deceleration).
Starting and driving5-113

CAUTION
During the first 1,200 miles (2,000 km),
follow these recommendations to obtain
maximum engine performance and ensure
the future reliability and economy of your
new vehicle. Failure to follow these recom-
mendations may result in shortened engine
life and reduced engine performance.
• Avoid driving for long periods at constant speed, either fast or slow, and do not run
the engine over 4,000 rpm.
• Do not accelerate at full throttle in any gear.
• Avoid quick starts.
• Avoid hard braking as much as possible.
• Do not tow a trailer for the first 500 miles (805 kilometers). Your engine, axle or other
parts could be damaged. Follow these easy-to-use Fuel Efficient Driv-
ing Tips to help you achieve the most fuel
economy from your vehicle.
1.
Use Smooth Accelerator and Brake Pedal
Application
• Avoid rapid starts and stops.
• Use smooth, gentle accelerator and brake application whenever possible.
• Maintain constant speed while com- muting and coast whenever possible.
2. Maintain Constant Speed
• Look ahead to try and anticipate and minimize stops.
• Synchronizing your speed with traffic lights allows you to reduce your number
of stops.
• Maintaining a steady speed can mini- mize red light stops and improve fuel
efficiency.
3. Use Air Conditioning (A/C) at Higher Ve-
hicle Speeds
• Below 40 mph (64 km/h), it is more efficient to open windows to cool the
vehicle due to reduced engine load.
• Above 40 mph (64 km/h), it is more efficient to use A/C to cool the vehicle
due to increased aerodynamic drag. • Recirculating the cool air in the cabin
when the A/C is on reduces cooling
load.
4.
Drive at Economical Speeds and Distances
•Observing the speed limit and not ex-
ceeding 60 mph (97 km/h) (where legally
allowed) can improve fuel efficiency due
to reduced aerodynamic drag.
• Maintaining a safe following distance behind other vehicles reduces unneces-
sary braking.
• Safely monitoring traffic to anticipate changes in speed permits reduced brak-
ing and smooth acceleration 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 effective 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.

SONAR LIMITATIONS
WARNING
Listed below are the system limitations for
the sonar system. Failure to operate the
vehicle in accordance with these system
limitations could result in serious injury or
death.
• The system is deactivated at speeds
above 6 mph (10 km/h). It is reactivated
at lower speeds.
• Inclement weather or ultrasonic sources
such as an automatic car wash, a truck’s
compressed-air brakes or a pneumatic
drill may affect the function of the sys-
tem; this may include reduced perfor-
mance or a false activation.
• The system is not designed to prevent
contact with small or moving objects. Al-
ways move slowly. The system will not
detect small objects below the bumper or
on the ground.
• The system may not detect the following
objects: fluffy objects such as snow,
cloth, cotton, glass-wool, etc.; thin ob-
jects such as rope, wire and chain, etc.; or
wedge-shaped objects. •
The system may not detect objects at
speeds above 3 mph (5 km/h) and may
not detect certain angular or moving
objects.
• Do not attach stickers (including trans-
parent material), install accessories, or
apply anything blocking the sensors.
These conditions may reduce the ability
of the system.
SYSTEM TEMPORARILY
UNAVAILABLE
When sonar blockage is detected, the system
will be deactivated automatically.
The system is not available until the condi-
tions no longer exist.
The sonar sensors may be blocked by tempo-
rary ambient conditions such as splashing
water, mist or fog. The blocked condition
may also be caused by objects such as ice,
frost or dirt obstructing the sonar sensors.
Action to take:
When the above conditions no longer exist,
the system will resume automatically.
SYSTEM MAINTENANCE
The sonar sensors are located on the front
and rear bumpers. Always keep the area near
the sonar sensors clean.
The sonar sensors may be blocked by tempo-
rary ambient conditions such as splashing
water, mist or fog.
The blocked condition may also be caused by
objects such as ice, frost or dirt obstructing
the sonar sensors.

5-152Starting and driving

•When using a wheel without TPMS such
as the spare tire, the TPMS will not func-
tion and the low tire pressure warning
light will flash for approximately 1 min-
ute. The light will remain on after 1 min-
ute. Have your tires replaced and/or
TPMS system reset as soon as possible.
It is recommended that you visit an
INFINITI retailer for these services.
• Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
• Do not inject any tire liquid or aerosol tire
sealant into the tires, as this may cause a
malfunction of the tire pressure sensors.
RUN-FLAT TIRES
This vehicle is equipped with run-flat tires.
Run-flat tires can be used temporarily if they
are punctured. When the “Flat Tire — Visit
dealer” warning appears in the vehicle infor-
mation display, one or more of your tires is
punctured. For additional information, see
“Run-flat tires” (P. 8-36).
For additional information, refer to the tire
safety information in the Warranty Informa-
tion Booklet.
WARNING
• Although you can continue driving with a
punctured run-flat tire, remember that
vehicle handling stability is reduced,
which could lead to an accident and per-
sonal injury. Also, driving a long distance
at high speeds may damage the tires.
• Do not drive at speeds above 50 mph
(80 km/h) and do not drive more than
approximately 93 miles (150 km) with a
punctured run-flat tire. The actual dis-
tance the vehicle can be driven on a flat
tire depends on outside temperature,
vehicle load, road conditions and other
factors.
• Drive safely at reduced speeds. Avoid
hard cornering or braking, which may
cause you to lose control of the vehicle.
• If you detect any unusual sounds or vi-
brations while driving with a punctured
run-flat tire, pull off the road to a safe
location and stop the vehicle as soon as
possible. The tire may be seriously dam-
aged and need to be replaced.CAUTION
• Never install tire chains on a punctured
run-flat tire, as this could damage your
vehicle.
• Avoid diving over any projection or pot-
hole, as the clearance between the ve-
hicle and the ground is smaller than
normal.
• Do not enter an automated car wash
with a punctured run-flat tire.
• Have the punctured tire inspected by an
INFINITI retailer or other authorized re-
pair shop. Replace the tire as soon as
possible if the tire is seriously damaged.

steam or coolant escaping from the radia-
tor before opening the hood. (If steam or
coolant is escaping, turn off the engine.)
Do not open the hood further until no
steam or coolant can be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
6. Visually check drive belts for damage or looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leaking,
the water pump belt is missing or loose, or
the cooling fan does not run, stop the
engine.

7. After the engine cools down, check thecoolant level in the engine coolant reser-
voir tank with the engine running. Add
coolant to the engine coolant reservoir
tank if necessary. Have your vehicle re-
paired. It is recommended that you visit an
INFINITI retailer for this service.When towing your vehicle, all jurisdictions and
local regulations for towing must be followed.
Incorrect towing equipment could damage
your vehicle. Towing instructions are available
from an INFINITI retailer. Local service opera-
tors are generally familiar with the applicable
laws and procedures for towing. To assure
proper towing and to prevent accidental dam-
age to your vehicle, INFINITI recommends
having a service operator tow your vehicle. It is
advisable to have the service operator care-
fully read the following precautions:
WARNING
• Never ride in a vehicle that is being
towed.
• Never get under your vehicle after it has
been lifted by a tow truck.
CAUTION
• When towing, make sure that the trans-
mission, axles, steering system and pow-
ertrain are in working condition. Use dol-
lies or flatbed if any of the listed systems
are not working.
• Always attach safety chains before
towing. For additional information about towing your
vehicle behind a Recreational Vehicle (RV),
