WARNING
•Never leave children or adults who
would normally require the support of
others alone in your vehicle. Pets should
not be left alone either. They could un-
knowingly activate switches or controls
and inadvertently become involved in a
serious accident and injure themselves.
On hot, sunny days, temperatures in a
closed vehicle could quickly become high
enough to cause severe or possibly fatal
illness to people or animals.
•Properly secure all cargo to help prevent
it from sliding or shifting. Do not place
cargo higher than the seatbacks. In a
sudden stop or collision, unsecured
cargo could cause personal injury.
•To avoid raising the center of gravity
excessively, do not exceed the rated ca-
pacity of the roof rack (if so equipped)
and evenly distribute the load.
EXHAUST GAS (CARBON
MONOXIDE)
WARNING
•Do not breathe exhaust gas; it contains
colorless and odorless carbon monoxide.
Carbon monoxide is dangerous. It can
cause unconsciousness or death.
•If you suspect that exhaust fumes are
entering the vehicle, drive with all win-
dows fully open, and have the vehicle
inspected immediately.
•Do not run the engine in closed spaces
such as a garage.
•Do not park the vehicle with the engine
running for an extended period of time.
•Keep the lift gate closed while driving,
otherwise exhaust gas could be drawn
into the passenger compartment. If you
must drive with the lift gate open, fol-
low these precautions:
–Open all the windows.
–Turn the air recirculation switch off
and set the fan control to the highest
level to circulate the air.
•If electrical wiring or other cable con-
nections must pass to a trailer through
the seal ion the lift gate or body, follow
the manufacturer's recommendations
to prevent carbon monoxide entry into
the vehicle.
•The exhaust system and body should be
inspected by a qualified mechanic when-
ever:
–You suspect that exhaust fumes are
entering into the passenger compart-
ment.
–You notice a change in the sound of
the exhaust system.
–You have had an accident involving
damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
(IF EQUIPPED)
The three-way catalyst is an emission control
device installed in the exhaust system. Ex-
haust gas in the three-way catalyst is burned
at high temperatures to help reduce pollut-
ants.
PRECAUTIONS WHEN STARTING
AND DRIVING
5-2Starting and driving

WARNING
•The exhaust gas and the exhaust system
are very hot. Keep people, animals and
flammable materials away from the ex-
haust system components.
•Do not stop or park the vehicle over
flammable materials such as dry grass,
wastepaper or rags. They may ignite
and cause a fire.
CAUTION
•Do not use leaded gasoline. (See "Rec-
ommended fluids/lubricants and ca-
pacities".) Deposits from leaded gaso-
line seriously reduce the ability of the
three-way catalyst to help reduce ex-
haust pollutants and/or damage the
three-way catalyst.
•Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems may cause overrich
fuel to flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if noticeable
loss of performance or other unusual op-
erating conditions are detected. Have
the vehicle inspected promptly. It is rec-ommended you visit an INFINITI retailer
for this service.
•Avoid driving with an extremely low fuel
level. Running out of fuel could cause the
engine to misfire, damaging the three-
way catalyst.
•Do not race the engine while warming it
up.
•Do not push or tow your vehicle to start
the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if present),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label.
(If your vehicle has tires of a different size
than the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of yourtires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your tires
as soon as possible, and inflate them to the
proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er’s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the
system detects a malfunction, the telltale will
flash for approximately one minute and then
remain continuously illuminated. This se-
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illumi-
nated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
Starting and driving5-3

•Do not shift gears while driving on
downhill grades as this could cause loss
of control of the vehicle.
•Stay alert when driving to the top of a
hill. At the top there could be a drop-off
or other hazard that could cause an ac-
cident.
•If your engine stalls or you cannot make
it to the top of a steep hill, never at-
tempt to turn around. Your vehicle could
tip or roll over. Always back straight
down in R (Reverse) gear and apply
brakes to control your speed.
•Heavy braking going down a hill could
cause your brakes to overheat and fade,
resulting in loss of control and an acci-
dent. Apply brakes lightly and use a low
gear to control your speed.
•Unsecured cargo can be thrown around
when driving over rough terrain. Prop-
erly secure all cargo so it will not be
thrown forward and cause injury to you
or your passengers.
•Secure heavy loads in the cargo area as
far forward and as low as possible. Do
not equip the vehicle with tires larger
than specified in this manual. This could
cause your vehicle to roll over.
•Do not grip the inside or spokes of the
steering 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 af-
fected by strong side winds. Slower
speeds ensure better vehicle control.
•Do not drive beyond the performance
capability 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 drive-
train 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 dyna-
mometer (such as the dynamometers
used by some states for emissions test-
ing), or similar equipment even if the
other two wheels are raised off the
ground. Make sure you inform test facil-
ity 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 move-
ment which could result in serious ve-
hicle 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 cen-
ter of gravity than a passenger car. The
vehicle is not designed for cornering at
the same speeds as passenger cars. Fail-
ure to operate this vehicle correctly
could result in loss of control and/or a
rollover accident.
Starting and driving5-11

•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. .
•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 schedules".
ALL-WHEEL DRIVE (AWD)
DRIVING SAFETY PRECAUTIONS
(IF SO EQUIPPED)
WARNING
•Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
•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.
•This vehicle is not designed for off-road
(rough road) use. Do not drive on sandy
or muddy roads that tires may get stuck
in.
•For AWD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to any
D (Drive) or R (Reverse) position with
the engine running. Doing so may result
in drivetrain damage or unexpected ve-
hicle movement which could result in se-
rious vehicle damage or personal injury
•Do not attempt to test an AWD
equipped vehicle on a 2-wheel dyna-
mometer, (such as the dynamometers
used by some states for emissions test-
ing), or similar equipment even if the
other two wheels are raised off the
ground. Make sure you inform test facil-
ity 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 move-
ment which could result in serious ve-
hicle damage or personal injury.
•When a wheel is off the ground due to an
