WARNING
●Do not leave children or adults who
would normally require the assistance
of others alone in your vehicle. Pets
should also not be left alone. They
could accidentally injure themselves or
others through inadvertent operation of
the vehicle. Also, on hot, sunny days,
temperatures in a closed vehicle could
quickly become high enough to cause
severe or possibly fatal injuries to
people or animals.
● Properly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or col-
lision, unsecured cargo could cause
personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
● Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is danger-
ous. 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 any extended length of time.
● Keep the rear vent windows, liftgates,
doors and trunk lids (if so equipped)
closed while driving, otherwise exhaust
gases could be drawn into the passen-
ger compartment. If you must drive with
one of these open, follow these
precautions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial to
high to circulate the air.
● If electrical wiring or other cable con-
nections must pass to a trailer through
the seal on the liftgate or the body,
follow the manufacturer’s recommen-
dation to prevent carbon monoxide en-
try into the vehicle. ●
The exhaust system and body should be
inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involving damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
WARNING
●The exhaust gas and the exhaust sys-
tem are very hot. Keep people, animals
or flammable materials away from the
exhaust system components.
PRECAUTIONS WHEN STARTING
AND DRIVING
5-4Starting and driving

●Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
CAUTION
● Do not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants.
● Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly by an INFINITI retailer.
● 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 provided) ,
should be checked monthly when cold and in-
flated to the inflation pressure recommended 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 Monitoring System
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly
under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check all four 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 driver’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 mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately 1 minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction indicator is
illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons,
including the installation of replacement or alter-
nate tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replac-
ing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Additional information:
● The TPMS does not monitor the tire
pressure of the spare tire.
Starting and driving5-5

●When a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI retailer as soon
as possible for tire replacement and/or
system resetting.
● 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.
CAUTION
● The TPMS may not function properly
when the wheels are equipped with tire
chains or the wheels are buried in snow.
● Do not place metalized film or any
metal parts (antenna, etc.) on the win-
dows. This may cause poor reception of
the signals from the tire pressure sen-
sors, and the TPMS will not function
properly. Some devices and transmitters may temporarily
interfere with the operation of the TPMS and
cause the low tire pressure warning light to illu-
minate.
Some examples are:
– Facilities or electric devices using similar radio
frequencies are near the vehicle.
– If a transmitter set to similar frequencies is being used in or near the vehicle.
– If a computer (or similar equipment) or a DC/AC converter is being used in or near the
vehicle.

TPMS with Tire Inflation Indicator
When adding air to an under-inflated tire, the
TPMS with Tire Inflation Indicator provides visual
and audible signals outside the vehicle to help
you inflate the tires to the recommended COLD
tire pressure.
Vehicle set-up:
1. Park the vehicle in a safe and level place.
2. Apply the parking brake and place the shift lever into the P (Park) position.
3. Place the ignition switch to the ON position. Do not start the engine.
Starting and driving5-7

●Do not drive across steep slopes. In-
stead drive either straight up or straight
down the slopes. Off-road vehicles can
tip over sideways much more easily
than they can forward or backward.
● Many hills are too steep for any vehicle.
If you drive up them, you may stall. If
you drive down them, you may not be
able to control your speed. If you drive
across them, you may roll over.
● 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
accident.
● 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 sud-
denly 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
drivetrain damage or unexpected ve-
hicle movement which could result in
serious vehicle damage or personal
injury.
● Do not attempt to test a 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 unex-
pected vehicle movement which could
result in serious vehicle damage or per-
sonal injury.
● When a wheel is off the ground due to
an unlevel surface, do not spin the
wheel excessively.
Starting and driving5-11

●Accelerating quickly, sharp steering
maneuvers or sudden braking may
cause loss of control.
● If at all possible, avoid sharp turning
maneuvers, 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.
Failure to operate 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 immedi-
ately after driving in mud or water. For
additional information, refer to “Brake
system” in this section for “Wet
brakes”.
● 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 infor-
mation, refer to “Periodic maintenance”
in the “INFINITI Service and Mainte-
nance Guide.”WARNING
Do not operate the push-button ignition
switch while driving the vehicle except in
an emergency. (The engine will stop when
the ignition switch is pushed three con-
secutive times in quick succession or the
ignition switch is pushed and held for
more than 2 seconds.) If the engine stops
while the vehicle is being driven, this
could lead to a crash and serious injury.
