CONVENTIONAL (fixed speed)
CRUISE CONTROL MODE
NOTE:
ProPILOT Assist provides no approach
warnings, automatic braking, or steering as-
sist in the conventional (fixed speed) cruise
control mode.
This mode allows driving at a speed between
25 to 90 mph (40 to 144 km/h) without
keeping your foot on the accelerator pedal.
WARNING
• In the conventional (fixed speed) cruise
control mode, a warning chime does not
sound to warn you if you are too close to
the vehicle ahead, as neither the pres-
ence of the vehicle ahead nor the vehicle-
to-vehicle distance is detected.
• Pay special attention to the distance be-
tween your vehicle and the vehicle ahead
of you or a collision could occur. •
Always confirm the setting in the ICC
system display.
• Do not use the conventional (fixed
speed) cruise control mode when driving
under the following conditions:
– When it is not possible to keep the
vehicle at a set speed
– In heavy traffic or in traffic that var-
ies in speed
– On winding or hilly roads
– On slippery roads (rain, snow, ice,
etc.)
– In very windy areas
• Doing so could cause a loss of vehicle
control and result in an accident.

ate the equipment.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.

CAUTION
• Continuously Variable Transmission
(CVT) models cannot be push-started or
tow-started. Attempting to do so may
cause transmission damage.
• Do not push start this vehicle. The three-
way catalyst may be damaged.WARNING
• Do not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
• To avoid the danger of being scalded,
never remove the coolant reservoir cap
while the engine is still hot. When the
coolant reservoir cap is removed, pres-
surized hot water will spurt out, possibly
causing serious injury.
• Do not open the hood if steam is coming
out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading),
or if you feel a lack of engine power, detect
abnormal noise, etc. take the following steps.
1. Move the vehicle safely off the road, apply the parking brake and engage the P (Park)
position.
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed. 3. Get out of the vehicle. Look and listen for
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.
4. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
5. 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.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling fan
can start at any time.
PUSH STARTING IF YOUR VEHICLE OVERHEATS
In case of emergency6-7

The engine cooling system is filled at the
factory with a pre-diluted mixture of 50%
Genuine NISSAN Long Life Antifreeze/
Coolant (blue) and 50% water to provide
year-round antifreeze and coolant protec-
tion. The antifreeze solution contains rust
and corrosion inhibitors. Additional engine
cooling system additives are not necessary.
WARNING
• Never remove the coolant reservoir cap
when the engine is hot. Wait until the
engine and radiator cool down. Serious
burns could be caused by high pressure
fluid escaping from the radiator. For ad-
ditional information on precautions, see
“If your vehicle overheats” (P. 6-7).
• The coolant reservoir is equipped with a
pressure type coolant reservoir cap. To
prevent engine damage, use only a Genu-
ine NISSAN coolant reservoir cap.
CAUTION
• Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause dam-
age to the engine, transmission and/or
cooling system.
• When adding or replacing coolant, be
sure to use only Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or
equivalent. Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-diluted
to provide antifreeze protection to -34°
F (-37° C). If additional freeze protection
is needed due to weather where you op-
erate your vehicle, add Genuine NISSAN
Long Life Antifreeze/Coolant (blue)
concentrate following the directions on
the container. If an equivalent coolant
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s instruc-
tions to maintain minimum antifreeze
protection to -34° F (-37° C). The use of
other types of coolant solutions other
than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent
may damage the engine cooling system. •
The life expectancy of the factory-fill
coolant is 105,000 miles (168,000 km)
or 7 years. Mixing any other type of cool-
ant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) (or
equivalent coolant), including Genuine
NISSAN Long Life Antifreeze/Coolant
(green), or the use of non-distilled water
may reduce the life expectancy of the
factory-fill coolant. For additional infor-
mation, see “Maintenance and sched-
ules” (P. 9-2).

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir when
the engine is cold. If the coolant level is below
the MIN level
OB, add coolant to the MAX
level
OA.
This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue). The life ex-
pectancy of the factory-fill coolant is
105,000 miles (168,000 km) or 7 years.
Mixing any other type of coolant or the use of
non-distilled water will reduce the life expec-
tancy of the factory-fill coolant. For addi- tional information, see "Maintenance and
schedules" (P. 9-2).
If the cooling system frequently requires
coolant, have it checked. It is recommended
that you visit an INFINITI retailer for this
service.
For additional information on the location of
the engine coolant reservoir, see “Engine
compartment check locations” (P. 8-3).
CHANGING ENGINE COOLANT
An INFINITI retailer can change the engine
coolant. The service procedure can be found
in the INFINITI Service Manual.
Improper servicing can result in reduced
heater performance and engine overheating.
WARNING
• To avoid the danger of being scalded,
never change the coolant when the en-
gine is hot.
• Never remove the coolant reservoir cap
when the engine is hot. Serious burns
could be caused by high pressure fluid
escaping from the radiator. •
Avoid direct skin contact with used cool-
ant. If skin contact is made, wash thor-
oughly with soap or hand cleaner as soon
as possible.
• Keep coolant out of the reach of children
and pets.
Engine coolant must be disposed of properly.
