PRECAUTIONS ON SUPPLEMENTAL
RESTRAINT SYSTEM
This Supplemental Restraint System (SRS) sec-
tion contains important information concerning
the following systems.
● Driver and passenger supplemental front-
impact air bag (INFINITI Advanced Air Bag
System)
● Front seat-mounted side-impact supplemen-
tal air bag
● Roof-mounted curtain side-impact and roll-
over supplemental air bag
● Seat belt with pretensioner
Supplemental front-impact air bag system: The
INFINITI Advanced Air Bag System can help
cushion the impact force to the head and chest
of the driver and front passenger in certain
frontal collisions.
Front seat-mounted side-impact supplemental
air bag system: This system can help cushion
the impact force to the chest and pelvis area of
the driver and front passenger in certain side
impact collisions. The supplemental side air
bag is designed to inflate on the side where the
vehicle is impacted. Roof-mounted curtain side-impact and rollover
supplemental air bag system:
This system can
help cushion the impact force to the head of
occupants in front and rear (2nd and 3rd)
outboard seating positions in certain side im-
pact or rollover collisions. In a side impact, the
curtain and rollover air bags are designed to
inflate on the side where the vehicle is im-
pacted. In a rollover both curtain and rollover
air bags are designed to inflate and remain
inflated for a short period of time.
These supplemental restraint systems are de-
signed to supplement the crash protection pro-
vided by the driver and passenger seat belts
and are not a substitute for them. Seat belts
should always be correctly worn and the occu-
pant seated a suitable distance away from the
steering wheel, instrument panel and door fin-
ishers. (See “SEAT BELTS” earlier in this section
for instructions and precautions on seat belt
usage.)
The supplemental air bags operate only when
the ignition switch is in the ON position.
After pushing the ignition switch to the ON posi-
tion, the supplemental air bag warning light illu-
minates. The supplemental air bag warning light
will turn off after about 7 seconds if the systems
are operational.

SUPPLEMENTAL RESTRAINT SYSTEM
1-50Safety — Seats, seat belts and supplemental restraint system

If an adult occupant is in the seat but the
passenger air bag status light is illuminated
(indicating that the air bag is OFF), it could be
that the person is a small adult, or is not sitting
on the seat properly.
If a child restraint must be used in the front
seat, the passenger air bag status light may or
may not be illuminated, depending on the size
of the child and the type of child restraint being
used. If the passenger air bag status light is not
illuminated (indicating that the air bag might
inflate in a crash), it could be that the child
restraint or seat belt is not being used properly.
Make sure that the child restraint is installed
properly, the seat belt is used properly and the
occupant is positioned properly. If the passen-
ger air bag status light is still not illuminated,
reposition the occupant or child restraint in a
rear seat.
If the passenger air bag status light will not
illuminate even though you believe that the
child restraint, the seat belts and the occupant
are properly positioned, the system may be
sensing an unoccupied seat (in which case the
air bag is OFF). Your INFINITI retailer can check
that the system is OFF by using a special tool.
However, until you have confirmed with your
retailer that your air bag is working properly,
reposition the occupant or child restraint in a
rear seat.The INFINITI Advanced Air Bag System and
passenger air bag status light will take a few
seconds to register a change in the passenger
seat status. However, if the seat becomes un-
occupied, the air bag status light will remain
off.
If a malfunction occurs in the front passenger
air bag system, the supplemental air bag warn-
ing light
, located in the meter and
gauges area will blink. Have the system
checked by an INFINITI retailer.
Other supplemental front-impact air
bag precautions
WARNING
● Do not place any objects on the steering
wheel pad or on the instrument panel. Also,
do not place any objects between any occu-
pant and the steering wheel or instrument
panel. Such objects may become dangerous
projectiles and cause injury if the front air
bags inflate. ●
Do not place objects with sharp edges on the
seat. Also, do not place heavy objects on the
seat that will leave permanent impressions
in the seat. Such objects can damage the
seat or occupant classification sensors
(weight sensors). This can affect the opera-
tion of the air bag system and result in seri-
ous personal injury.
● Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can dam-
age the seat or occupant classification sen-
sors. This can also affect the operation of the
air bag system and result in serious personal
injury.
● Immediately after inflation, several front air
bag system components will be hot. Do not
touch them; you may severely burn yourself.
● No unauthorized changes should be made to
any components or wiring of the supplemen-
tal air bag system. This is to prevent acciden-
tal inflation of the supplemental air bag or
damage to the supplemental air bag system.
● Do not make unauthorized changes to your
vehicle’s electrical system, suspension sys-
tem or front end structure. This could affect
proper operation of the front air bag system.
Safety — Seats, seat belts and supplemental restraint system1-59

CAUTION
●The TPMS is not a substitute for the regular
tire pressure check. Be sure to check the tire
pressure regularly.
● If the vehicle is being driven at speeds of less
than 16 MPH (25 km/h), the TPMS may not
operate correctly.
● Be sure to install the specified size of tires to
the four wheels correctly.
Master warning light
When the ignition switch is in the ON position,
the master warning light illuminates if any of
the following are displayed on the dot matrix
liquid crystal display:
● No key warning
● Low fuel warning
● Low washer fluid warning
● Parking brake release warning
● Door/lift gate open warning
● Loose fuel cap warning (if so equipped)

Preview Function warning
light (orange; if so equipped)
The light comes on if there is a malfunction in
the Brake Assist (with Preview Function) sys-
tem.
If the warning light comes on, park the vehicle
in a safe place. Turn the engine off, restart the
engine, then resume driving.
If it is not possible to set the system or the
indicator stays on, it may indicate that the sys-
tem is malfunctioning. Although the vehicle is
still driveable under normal conditions, have the
vehicle checked at an INFINITI retailer.
Seat belt warning light and
chime
The light and chime remind you to fasten seat
belts. The light illuminates whenever the igni-
tion switch is pushed to the ON position, and
will remain illuminated until the driver’s seat
belt is fastened. At the same time, the chime
will sound for about 6 seconds unless the
driver’s seat belt is securely fastened.
The seat belt warning light for the front passen-
ger will illuminate if the seat belt is not fastened
when the front passenger’s seat is occupied.
For approximately 5 seconds after the ignition switch is in the ON position, the system does
not activate the warning light for the front
passenger.
See “SEAT BELTS” in the “1. Safety — Seats,
seat belts and supplemental restraint system”
section for precautions on seat belt usage.
Supplemental air bag
warning light
After pushing the ignition switch to the ON
position, the supplemental air bag warning
light will illuminate. The supplemental air bag
warning light will turn off after about 7 seconds
if the front-impact air bag and side air bag,
curtain and rollover air bag systems and/or
pretensioner seat belts are operational.
If any of the following conditions occur, the
front air bag, side air bag, curtain and rollover
air bag and pretensioner systems needs servic-
ing and your vehicle must be taken to your
nearest INFINITI retailer.
●
The supplemental air bag warning light re-
mains on after approximately 7 seconds.
● The supplemental air bag warning light
flashes intermittently.
● The supplemental air bag warning light does
not come on at all.

NOTE:
When the monitor displays the front view and
the steering wheel turns about 90 degrees or
less from the neutral position, both the right and
left predictive course lines
6are displayed.
When the steering wheel turns about 90 degrees
or more, a line is displayed only on the opposite
side of the turn.
Bird-eye view
The bird-eye view shows the overhead view of
the vehicle which helps confirm the vehicle
position and the predicted course to a parking
space.
The vehicle icon
1shows the position of the
vehicle. Note that the size of the vehicle icon on
the bird-eye view may differ somewhat from the
actual vehicle.
The areas that the cameras cannot cover
2are
indicated in black.
After pushing the ignition switch, with the
Non-viewable Area turned to ON, the non-
viewable area
2is highlighted in yellow for 7
seconds after the bird-eye view is displayed. When the corner of the vehicle moves closer to
an object, the corner sonar indicator

pears.
WARNING
● Objects in the bird-eye view will appear fur-
ther than the actual distance because the
bird-eye view is a pseudo view that is pro-
cessed by combining the views from the
cameras on the outside mirrors, the front
and the rear of the vehicle.
● Tall objects, such as a curb or vehicle, may
be misaligned or not displayed at the seam
of the views.
● Objects that are above the camera cannot be
displayed.
● The view for the bird-eye view may be mis-
aligned when the camera position alters.
● A line on the ground may be misaligned and
is not seen as being straight at the seam of
the views. The misalignment will increase as
the line proceeds away from the vehicle.

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 electrical sys-
tems 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 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
inflated 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 pres-
sure 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 4 tires as soon as
possible, and inflate them to the proper pres-
sure. 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 combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approxi-
mately one minute and then remain continu-
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
the malfunction 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 alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. 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.
Starting and driving5-3

●Always use tires of the same type, size,
brand, construction (bias, bias-belted or ra-
dial), 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 immediately af-
ter driving in mud or water. See “BRAKE SYS-
TEM” later 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. See
the maintenance information in the “INFINITI
Service and Maintenance Guide”.
● Spinning the rear wheels on slippery sur-
faces may cause the 4WD warning light to
flash. The 4WD system may also automati-
cally switch from the 4WD mode to the 2WD
mode. This could reduce traction. Be espe-
cially careful when towing a trailer (4WD
models).WARNING
Do not operate the push-button ignition switch
while driving the vehicle except in an emer-
gency. (The engine will stop when the ignition
switch is pushed 3 consecutive times 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.
Before operating the push-button ignition
switch, be sure to move the selector lever to the
P (Park) position.
OPERATING RANGE FOR ENGINE
START FUNCTION
The operating range for starting the engine
inside the vehicle
1is shown in the illustra-
tion.
● If the Intelligent Key is on the instrument
panel, cargo area, inside the glove box or
door pocket, or the corner of interior com-
partment, it may not be possible to start the
engine.
● If the Intelligent Key is near the door or door
glass outside the vehicle, it may be possible
to start the engine.

Warning light and display
When the Preview Function is not operating
properly, the chime sounds and the system
warning light (orange) will come on.
Action to take :
If the warning light comes on, park the vehicle
in a safe place. Turn the engine off, restart the
engine and resume driving.
If the indicator stays on, it may indicate that the
Preview Function is malfunctioning (the brake is
operative). Although the Vehicle is still drive-
able under normal conditions, have the vehicle
checked at an INFINITI retailer.
How to handle the sensor
The sensor for the Preview Function is common
with Intelligent Cruise Control and is located
below the front bumper.
To keep the Preview Function operating prop-
erly, be sure to observe the following:
●Always keep the sensor clean. Wipe with a
soft cloth carefully so as not to damage the
sensor.
● Do not strike or damage the areas around
the sensor. Do not touch or remove the
screw located on the sensor. Doing so could
cause failure or malfunction. If the sensor is
damaged due to an accident, contact an
INFINITI retailer.
● Do not attach a sticker (including transpar-
ent material) or install an accessory near the
sensor. This could cause failure or malfunc-
tion.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
● The Anti-lock Braking System (ABS) is a so-
phisticated device, but it cannot prevent ac-
cidents resulting from careless or dangerous
driving techniques. It can help maintain ve-
hicle control during braking on slippery sur-
faces. Remember that stopping distances on
slippery surfaces will be longer than on nor-
mal surfaces even with ABS. Stopping dis-
tances 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 brak-
ing 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 LABEL”
in the “9. Technical and consumer informa-
tion” section of this manual.
– For detailed information, see “WHEELS AND TIRES” in the “8. Maintenance and
do-it-yourself” section of this manual.

FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the
key hole or use the Intelligent Key system.
ANTIFREEZE
In the winter when it is anticipated that the
outside temperature will drop below 32°F (0°C),
check antifreeze to assure proper winter protec-
tion. For additional information, see “ENGINE
COOLING SYSTEM” in the “8. Maintenance and
do-it-yourself” section.
BATTERY
If the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For additional
information, see “BATTERY” in the “8. Mainte-
nance and do-it-yourself” section.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For details, see “ENGINE COOLING SYS-
TEM” in the “8. Maintenance and do-it-yourself”
section.
TIRE EQUIPMENT
SUMMER tires have a tread designed to provide
superior performance on dry pavement. How-
ever, the performance of these tires will be
substantially reduced in snowy and icy condi-
tions. If you operate your vehicle on snowy or
icy roads, INFINITI recommends the use of MUD
& SNOW or ALL SEASON tires on all four wheels.
Consult an INFINITI retailer for the tire type,
size, speed rating and availability information.
For additional traction on icy roads, studded
tires may be used. However, some U.S. states
and Canadian provinces prohibit their use.
Check local, state and provincial laws before
installing studded tires.
Skid and traction capabilities of studded snow
tires, on wet or dry surfaces, may be poorer than
that of non-studded snow tires.
Tire chains may be used. For details, see “TIRE
CHAINS” in the “8. Maintenance and do-it-
yourself” section of this manual.
For four-wheel drive
If you install snow tires, they must also be the
same size, brand, construction and tread pat-
tern on all four wheels.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the vehicle during winter:
●A scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
● A sturdy, flat board to be placed under the
jack to give it firm support.
● A shovel to dig the vehicle out of snowdrifts.
● Extra window washer fluid to refill the reser-
voir tank.
DRIVING ON SNOW OR ICE
WARNING
● Wet ice (32°F, 0°C and freezing rain), very
cold snow or ice can be slick and very hard to
drive on. The vehicle will have much less
traction or “grip” under these conditions.
Try to avoid driving on wet ice until the road
is salted or sanded.
● Whatever the condition, drive with caution.
Accelerate and slow down with care. If accel-
erating or downshifting too fast, the drive
wheels will lose even more traction.
COLD WEATHER DRIVING
Starting and driving5-101

TIRE LABELING
Federal law requires tire manufacturers
to place standardized information on the
sidewall of all tires. This information
identifies and describes the fundamen-
tal characteristics of the tire and also
provides the tire identification number
(TIN) for safety standard certification.
The TIN can be used to identify the tire in
case of a recall.
1Tire size (example: P215/60R16 94H)
1.P: The “P” indicates the tire is de-
signed for passenger vehicles. (Not all
tires have this information.)
2.Three-digit number (215): This num-
ber gives the width in millimeters of
the tire from sidewall edge to side-
wall edge.
3.Two-digit number (60): This number,
known as the aspect ratio, gives the
tire’s ratio of height to width.
4.R: The “R” stands for radial.
5.Two-digit number (16): This number is
the wheel or rim diameter in inches.
6.Two- or three-digit number (94): This
number is the tire’s load index. It is a
measurement of how much weight
each tire can support. You may not
find this information on all tires be-
cause it is not required by law.
7.H: Tire speed rating. You should not
drive the vehicle faster than the tire
speed rating.
