ENGINE COOLANT TEMPERATURE
GAUGE
The gauge indicates the engine coolant
temperature.
The engine coolant temperature is within
the normal range when the gauge needle
points within the zone
*1shown in the
illustration.
The engine coolant temperature varies with
the outside air temperature and driving
conditions.
CAUTION
If the gauge indicates engine coolant
temperature near the hot (H) end of the
normal range, reduce vehicle speed to
decrease temperature. If gauge is over the
normal range, stop the vehicle as soon as
safely possible and let the engine idle. If the
engine is overheated, continued operation
of the vehicle may seriously damage the
engine. See “If your vehicle overheats” (P.6-
12) for immediate action required.

function. However, this may result in
minor personal injury if someone is
behind the vehicle when the switch is
activated, or damage to the lift gate.
NOTE:
.To avoid damaging the lift gate system,
do not manually force the lift gate to
open or close when the lift gate is
moving. When manually operating the
lift gate from the full close or full open
position, do not use excessive force.
Using excessive force may damage the
system.
. Do not install accessories such as bike
racks onto the lift gate. The additional
weight of these accessories may cause
the lift gate to operate slowly or to not
open completely. This is a normal
operation and does not indicate a
malfunction. The lift gate will operate
normally when the accessory is re-
moved.
. If the lift gate is opened when the
vehicle is parked on a steep slope, the
lift gate may not open to the expected
position. This is a normal operation
and does not indicate a malfunction. .
If the automatic lift gate is operated
continuously for approximately 180
seconds, the system automatically
turns off to prevent overheating. The
lift gate cannot be opened using the
switches. The system resets and opera-
tion returns to normal after approxi-
mately 180 seconds. This is a normal
operation and does not indicate a
malfunction.
. The lift gate may automatically reverse
direction if the lift gate is operating
and passengers enter/exit the vehicle.
This is a normal operation and does
not indicate a malfunction.
. The lift gate must be operated manually
if the battery is disconnected or
discharged.
. If the lift gate is not activated due to a
low voltage (less than approximately
11V), operate the lift gate with the
engine running.
Manual mode
If power operation is not available, the lift
gate can be operated manually. Power
operation may not be available if multiple
obstacles have been detected in a single
power cycle or if the battery voltage is low. When the power lift gate main switch is in
the OFF position, the lift gate can be
opened manually by pushing the lift gate
opener switch. If the power lift gate opener
switch is pushed during power open or
close, the power operation will be canceled
and the lift gate can be operated manually.
AUTO CLOSURE
If the lift gate is pulled down to a partly
open position, the lift gate will pull itself to
the closed position.
Do not apply excessive force when the
auto closure is operating. Excessive force
applied may cause the mechanism to
malfunction.
CAUTION
.
The lift gate will automatically close
from a partly open position. To avoid
pinching, keep hands and fingers away
from lift gate opening.
. Do not let children operate the lift gate.

cause a fire.
CAUTION
.Do not use leaded gasoline. Deposits
from leaded gasoline seriously reduce
the three-way catalyst’s ability to help
reduce exhaust pollutants.
. Keep your engine tuned up. Malfunctions
in the ignition, fuel injection, or elec-
trical systems can cause overrich fuel
flow into the three-way catalyst, causing
it to overheat. Do not keep driving if the
engine misfires, or if noticeable loss of
performance or other unusual operating
conditions are detected. Have the vehicle
inspected promptly by an INFINITI retai-
ler.
. 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 SYS-
TEM (TPMS)
Each tire, including the spare (if provided),
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
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 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 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 malfunction indicator is com-
bined 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 sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the mal-
function indicator is illuminated, the sys-
tem may not be able to detect or signal low
tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons,
including the installation of replacement or
alternate tires or wheels on the vehicle that
prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction
telltale after replacing 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.

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 All-Wheel
Drive (AWD) 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
(Neutral), 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. Prop-
erly secure all cargo so it will not be
thrown forward and cause injury to you
or your passengers.
. 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. 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 became hot.
. Lower your speed when encountering
strong crosswinds. With a higher center
of gravity, your INFINITI is more affected

BRAKING PRECAUTIONS
The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
You may feel a small click and hear a sound
when the brake pedal is fully depressed
slowly. This is not a malfunction and
indicates that the brake assist mechanism
is operating properly.
Vacuum assisted brakes
The brake booster aids braking by using
engine vacuum. If the engine stops, you
can stop the vehicle by depressing the
brake pedal. However, greater foot pres-
sure on the brake pedal will be required to
stop the vehicle and the stopping distance
will be longer.
When the brake pedal is depressed slowly
and firmly, you may hear a clicking noise
and feel a slight pulsation. This is normal
and indicates that the Brake Assist System
is operating.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet.
As a result, your braking distance will be
longer and the vehicle may pull to one sideduring braking.
To dry brakes, drive the vehicle at a safe
speed while lightly tapping the brake pedal
to heat-up the brakes. Do this until the
brakes return to normal. Avoid driving the
vehicle at high speeds until the brakes
function correctly.
EUROPEAN DESIGN BRAKE PADS (if
so equipped)
The FX50 Sport (only) is equipped with
more aggressive European style brake
pads which provide increased fade resis-
tance when repeatedly braking from very
high speeds. These pads are likely to
experience increased brake dust and noise
as well as increased pad and rotor wear,
with replacement intervals of less than
20,000 miles (32,000 km) for some custo-
mers depending upon their driving pat-
terns.
PARKING BRAKE BREAK-IN
Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or drums/rotors are replaced,
in order to assure the best braking
performance.
This procedure is described in the vehicle
service manual and can be performed by
an INFINITI retailer.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will cause overheating
of the brakes, wearing out the brake and
pads faster and reduce gas mileage.
To help save the brakes and to prevent the
brakes from overheating, reduce speed
and downshift to a lower gear before going
down a slope or long grade. Overheated
brakes may reduce braking performance
and could result in loss of vehicle control.
WARNING
.
While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
