11. Low Fuel
This warning appears when the fuel level in
the tank is getting low. Refuel as soon as it is
convenient, preferably before the fuel gauge
reaches the 0 (Empty) position.
There is a small reserve of fuel remaining in
the tank when the fuel gauge reaches the 0
(Empty) position.
12. Low Washer Fluid
This warning appears when the washer tank
fluid is at a low level. Add washer fluid as
necessary. (See “Window washer fluid” (P.8-
10).)
13. Loose Fuel Cap
This warning appears when the fuel-filler
cap is not tightened correctly after the
vehicle has been refueled. (See “Fuel-filler
cap” (P.3-26).)
14. Tire Pressure Low Add Air
This warning appears when the low tire
pressure warning light in the meter illumi-
nates and low tire pressure is detected. The
warning appears each time the ignition
switch is placed in the ON position as long
as the low tire pressure warning lightremains illuminated. If this warning appears,
stop the vehicle and adjust the tire pressure
to the recommended COLD tire pressure
shown on the Tire and Loading Information
label. (See “Low tire pressure warning light”
(P.2-16) and “Tire Pressure Monitoring
System (TPMS)” (P.5-5).)

5-6Starting and driving
not detect a sudden drop in tire pressure
(for example, a flat tire while driving).
. The low tire pressure warning light does
not automatically turn off when the tire
pressure is adjusted. After the tire is
inflated to the recommended pressure,
the vehicle must be driven at speeds
above 16 MPH (25 km/h) to activate the
TPMS and turn off the low tire pressure
warning light. Use a tire pressure gauge
to check the tire pressure.
. The “Tire Pressure Low Add Air” warning
appears in the vehicle information dis-
play when the low tire pressure warning
light is illuminated and low tire pressure
is detected. The “Tire Pressure Low Add
Air” warning turns off when the low tire
pressure warning light turns off.
The “Tire Pressure Low Add Air” warning
appears each time the ignition switch is
placed in the ON position as long as the
low tire pressure warning light remains
illuminated.
The “Tire Pressure Low Add Air” warning
does not appear if the low tire pressure
warning light illuminates to indicate a
TPMS malfunction.
. Tire pressure rises and falls depending on
the heat caused by the vehicle’s opera-
tion and the outside temperature. Do not
reduce the tire pressure after driving
because the tire pressure rises after driving. Low outside temperature can
lower the temperature of the air inside
the tire which can cause a lower tire
inflation pressure. This may cause the
low tire pressure warning light to illumi-
nate. If the warning light illuminates in
low ambient temperature, check the tire
pressure for all four tires.
. You can also check the pressure of all
tires (except the spare tire) on the vehicle
information display. (See “10. Tire pres-
sures” (P.2-36).)
For additional information, see “Low tire
pressure warning light” (P.2-16) and “Tire
Pressure Monitoring System (TPMS) ” (P.6-
3).
WARNING
. If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possible.
Driving with under-inflated tires may
permanently damage the tires and
increase the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and
could result in serious personal injury. Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading
Information label to turn the low tire
pressure warning light OFF. If the
light still illuminates while driving
after adjusting the tire pressure, a
tire may be flat or the TPMS may be
malfunctioning. If you have a flat tire,
replace it with a spare tire as soon as
possible. If no tire is flat and all tires
are properly inflated, it is recom-
mended you consult an INFINITI
retailer.
. Since the spare tire is not equipped
with the TPMS, when a spare tire is
mounted or a wheel is replaced, 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. Have
your tires replaced and/or TPMS
system reset as soon as possible. It
is recommended you visit an INFINITI
retailer for these services.
. Replacing tires with those not origin-
ally 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

ABOUT LOWERING OF THE
REAR OF THE VEHICLE
If the loaded vehicle is not moved for a long
time, the vehicle rear body may be to lower.
But it is normal. Once the engine starts, It
will automatically adjust vehicle height.
DRINKING ALCOHOL/DRUGS
AND DRIVING
WARNING
Never drive under the influence of alco-
hol or drugs. Alcohol in the bloodstream
reduces coordination, delays reaction
time and impairs judgement. Driving
after drinking alcohol increases the like-
lihood of being involved in an accident
injuring yourself and others. Addition-
ally, if you are injured in an accident,
alcohol can increase the severity of the
injury.
INFINITI is committed to safe driving. How-
ever, you must choose not to drive under the
influence of alcohol. Every year thousands of
people are injured or killed in alcohol-related
accidents. Although the local laws vary on
what is considered to be legally intoxicated,
the fact is that alcohol affects all people differently and most people underestimate
the effects of alcohol.
Remember, drinking and driving don’t mix!
And that is true for drugs, too (over-the-
counter, prescription, and illegal drugs).
Don’t drive if your ability to operate your
vehicle is impaired by alcohol, drugs, or some
other physical condition.
DRIVING SAFETY PRECAUTIONS
Your INFINITI is designed for both normal
and off-road use. However, avoid driving in
deep water or mud as your INFINITI is
mainly designed for leisure use, unlike a
conventional off-road vehicle.
Remember that Two-Wheel Drive (2WD)
models are less capable than Four-Wheel
Drive (4WD) models for rough road driving
and extrication when stuck in deep snow,
mud, or the like.
Please observe the following precautions:
WARNING
.
Drive carefully when off the road and
avoid dangerous areas. Every person
who drives or rides in this vehicle
should be seated with their seat belt
fastened. This will keep you and your
passengers in position when driving over rough terrain.
. Do not drive across steep slopes.
Instead 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 ranges 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 attempt to turn around. Your
vehicle could tip or roll over. Always
back straight down in R (Reverse)
range. Never back down in N (Neu-
tral), using only the brake, as this
could cause loss of control.
. Heavy braking going down a hill
could cause your brakes to overheat

and fade, resulting in loss of control
and an accident. Apply brakes lightly
and use a low range to control your
speed.
. Unsecured cargo can be thrown
around when driving over rough
terrain. Properly secure all cargo so
it will not be thrown forward and
cause injury to you or your passen-
gers.
. To avoid raising the center of gravity
excessively, do not exceed the rated
capacity of the roof rack (if so
equipped) and evenly distribute the
load. 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. In-
stead 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 became 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 ensure better vehicle
control.
. Do not drive beyond the performance
capability of the tires, even with
4WD engaged.
. For 4WD equipped vehicles, do not
attempt 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 a 4WD
equipped vehicle on a 2-wheel dy-
namometer (such as the dynam-
ometers used by some states for
emissions testing), or similar equip-
ment even if the other two wheels are
raised off the ground. Make sure you
inform test facility personnel that
your vehicle is equipped with 4WD
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
personal injury (4WD models).
. When a wheel is off the ground due
to an unlevel surface, do not spin the
wheel excessively.
. 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 vehicle has a higher
center of gravity than a conventional
passenger car. The vehicle is not
designed for cornering at the same
speeds as conventional passenger
cars. Failure to operate this vehicle
correctly could result in loss of con-
trol 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 rear wheels when driving on
slippery roads and drive carefully.
. Be sure to check the brakes immedi-
ately after driving in mud or water.
See “Brake system” (P.5-133) for
wet brakes.
. Avoid parking your vehicle on steep
hills. If you get out of the vehicle and

When driving on the freeway at a set speed
and approaching a slower traveling vehicle
ahead, the ICC system will adjust the speed
to maintain the distance, selected by the
driver, from the vehicle ahead. If the vehicle
ahead changes lanes or exits the freeway,
the ICC system will accelerate and maintain
the speed up to the set speed. Pay attention
to the driving operation to maintain control
of the vehicle as it accelerates to the set
speed.
The vehicle may not maintain the set speed
on winding or hilly roads. If this occurs, you
will have to manually control the vehicle
speed.
Normally when controlling the distance to avehicle ahead, this system automatically
accelerates or decelerates your vehicle ac-
cording to the speed of the vehicle ahead.
Depress the accelerator to properly accel-
erate your vehicle when acceleration is
required for a lane change. Depress the
brake pedal when deceleration is required
to maintain a safe distance to the vehicle
ahead due to its sudden braking or if a
vehicle cuts in. Always stay alert when using
the ICC system.

incrementally.
3. DISTANCE switch: Changes the vehicle’s following distance:

5-116Starting and driving
.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 the wheels in correct alignment.
Improper alignment increases tire wear
and lowers fuel economy.
. Use the recommended viscosity engine
oil. (See “Engine oil and oil filter recom-
mendation” (P.10-6).)
WARNING
. Do not attempt to raise two wheels
off the ground and shift the trans-
mission to any drive or reverse posi-
tion 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 a 4WD
equipped vehicle on a 2-wheel dy-
namometer or similar equipment even
if the other two wheels are raised off
the ground. Make sure you inform
test facility personnel that your ve-
hicle is equipped with 4WD 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.
CAUTION
.Do not drive the vehicle in the 4HI or
4LO position on dry hard surface
roads. Driving on dry, hard surfaces in 4HI or 4LO may cause unnecessary
noise, tire wear and increased fuel
consumption.
If the Four-Wheel Drive (4WD)
warning light turns on when driving
on dry hard surface roads:
— in the 4HI position, shift the 4WD shift switch to AUTO.
— in the 4LO position, stop the vehicle and shift the transmission
lever to the N (Neutral) position
with the brake pedal depressed
and shift the 4WD shift switch to
AUTO.
If the 4WD warning light is still on
after the above operation, have
your vehicle checked. It is recom-
mended you visit an INFINITI
retailer for this service.
. The transfer case may be damaged if
you continue driving with the 4WD
warning light blinking.
See “On-pavement and off-road driving
precautions” (P.5-8) for other precautions
for offroad driving.

BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional brake booster even with
light pedal force.
WARNING
The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the
driver’s responsibility to stay alert, drive
safely and be in control of the vehicle at
all times.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
.The Anti-lock Braking System (ABS)
is a sophisticated device, but it
cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces. Remember that
stopping distances on slippery sur- faces will be longer than on normal
surfaces even with ABS. Stopping
distances may also be longer on
rough, gravel or snow covered roads,
or if you are using tire chains. Always
maintain a safe distance from the
vehicle in front of you. Ultimately,
the driver is responsible for safety.
. Tire type and condition may also
affect braking effectiveness.
— When replacing tires, install the specified size of tires on all four
wheels.
— When installing a spare tire, make sure that it is the proper size and
type as specified on the Tire and
Loading Information label. See
“Tire and loading information la-
bel” (P.10-13).
— For detailed information, see “Wheels and tires” (P.8-27).
The Anti-lock Braking System (ABS) controls
the brakes so the wheels do not lock during
hard braking or when braking on slippery
surfaces. The system detects the rotation
speed at each wheel and varies the brake
fluid pressure to prevent each wheel from
locking and sliding. By preventing each
wheel from locking, the system helps the driver maintain steering control and helps to
minimize swerving and spinning on slippery
surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
ABS will operate to prevent the wheels from
locking up. Steer the vehicle to avoid
obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer.
The computer has a built-in diagnostic
feature that tests the system each time you
start the engine and move the vehicle at a
low speed in forward or reverse. When the
self-test occurs, you may hear a “clunk”
noise and/or feel a pulsation in the brake
pedal. This is normal and does not indicate a
malfunction. If the computer senses a mal-
function, it switches the ABS off and
