∙ Do not grip the inside or spokes of thesteering wheel when driving off-road.
The steering wheel could move suddenly
and injure your hands. Instead drive with
your fingers and thumbs on the outside of
the rim.
∙ Before operating the vehicle, ensure that the driver and all passengers have their
seat belts fastened.
∙ Always drive with the floor mats in place as the floor may become hot.
∙ Lower your speed when encountering strong crosswinds. With a higher center
of gravity, your INFINITI is more affected
by strong side winds. Slower speeds en-
sure better vehicle control.
∙ Do not drive beyond the performance ca- pability of the tires, even with AWD
engaged.
∙ For AWD equipped vehicles, do not at- tempt to raise two wheels off the ground
and shift the transmission to any drive or
reverse position with the engine running.
Doing so may result in drivetrain damage
or unexpected vehicle movement which
could result in serious vehicle damage or
personal injury. ∙ Do not attempt to test an AWD equipped
vehicle on a 2-wheel dynamometer (such
as the dynamometers used by some
states for emissions testing) or similar
equipment even if the other two wheels
are raised off the ground. Make sure you
inform test facility personnel that your
vehicle is equipped with AWD before it is
placed on a dynamometer. Using the
wrong test equipment may result in
drivetrain damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
∙ When a wheel is off the ground due to an unlevel surface, do not spin the wheel
excessively.
∙ Accelerating quickly, sharp steering ma- neuvers or sudden braking may cause loss
of control.
∙ If at all possible, avoid sharp turning ma- neuvers, particularly at high speeds. Your
INFINITI vehicle has a higher center of
gravity than a passenger car. The vehicle
is not designed for cornering at the same
speeds as passenger cars. Failure to op-
erate this vehicle correctly could result in
loss of control and/or a rollover accident. ∙ Always use tires of the same type, size,
brand, construction (bias, bias-belted, or
radial), and tread pattern on all four
wheels. Install tire chains on the front
wheels when driving on slippery roads
and drive carefully.
∙ Be sure to check the brakes immediately after driving in mud or water. For addi-
tional information, refer to “Brake pre-
cautions” in this section.
∙ Avoid parking your vehicle on steep hills. If you get out of the vehicle and it rolls
forward, backward or sideways, you
could be injured.
∙ Whenever you drive off-road through sand, mud or water as deep as the wheel
hub, more frequent maintenance may be
required. For additional information, re-
fer to “Maintenance under severe oper-
ating conditions” in the “Maintenance
and schedules” section of this manual.

10.Keeping your Vehicle Cool
∙ Park your vehicle in a covered parking area or in the shade whenever pos-
sible.
∙ When entering a hot vehicle, opening the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C system. ∙ Keep your engine tuned up.
∙ Follow the recommended scheduled
maintenance.
∙ Keep the tires inflated to the correct pressure. Low tire pressure increases tire
wear and lowers fuel economy.
∙ Keep all the wheels in correct alignment. Improper alignment increases tire wear
and lowers fuel economy.
∙ Use the recommended viscosity engine oil. For additional information, refer to
“Engine oil and oil filter recommenda-
tions” in the “Technical and consumer in-
formation” section of this manual. If any malfunction occurs in the Intelligent
AWD system while the engine is running,
messages are displayed in the meter.

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
protection. The antifreeze solution contains
rust and corrosion inhibitors. Additional en-
gine cooling system additives are not neces-
sary.
WARNING
∙ Never remove the radiator or coolantreservoir 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 ra-
diator. For additional information on
precautions, refer to “If your vehicle
overheats” in the “In case of emergency”
section of this manual.
∙ The radiator is equipped with a pressure type radiator cap. To prevent engine
damage, use only a Genuine NISSAN ra-
diator cap.
CAUTION
∙ Never use any cooling system additivessuch 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) con-
centrate following the directions on the
container. If an equivalent coolant other
than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is used, follow
the coolant manufacturer’s instructions
to maintain minimum antifreeze protec-
tion 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), including
Genuine NISSAN Long Life
Antifreeze/Coolant (green), or the use of
non-distilled water will reduce the life
expectancy of the factory-fill coolant.
For additional information, refer to the
“Maintenance and schedules” section of
this manual.

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir when
the engine is cold. If the coolant level is below
the MIN level
B, add coolant to the MAX
level
A. If the reservoir is empty, check the
coolant level in the radiator when the engine
is cold. If there is insufficient coolant in the
radiator, fill the radiator with coolant up to
the filler opening and also add it to the reser-
voir up to the MAX level
A. 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, refer to the "Maintenance
and schedules" section of this manual.
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, refer to “Engine
compartment check locations” in this section.
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 radiator or engine 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.
