PRECAUTIONS ON SUPPLEMENTAL
RESTRAINT SYSTEM
GUID-2895B0A1-F440-45EC-B60A-EFF92C5563F8This Supplemental Restraint System (SRS)
section contains important information
concerning the driver and passenger front
impact supplemental air bags (INFINITI
Advanced Air Bag System), front seat-
mounted side-impact supplemental air
bag system, door-mounted curtain side-
impact supplemental air bag and seat belt
with pretensioners.
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 supple-
mental 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 front seat side-impact supplemental
air bags are designed to inflate on the side
where the vehicle is impacted.
Door-mounted curtain side-impact supple-
mental air bag system: This system can
help cushion the impact force to the head
of occupants in front seating positions in certain side impact or rollover collisions.
The curtain air bags are designed to inflate
on the side where the vehicle is impacted.
These supplemental restraint systems are
designed to
supplementthe crash protec-
tion provided by the driver and passenger
seat belts and are not a substitutefor
them. Seat belts should always be cor-
rectly worn and the occupant seated a
suitable distance away from the steering
wheel, instrument panel and door fin-
ishers. (See “Seat belts” (P.1-11) 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
position, the supplemental air bag warn-
ing light illuminates. The supplemental air
bag warning light will turn off after about
7 seconds if the systems are operational.

low tire pressure warning light. Use a tire
pressure gauge to check the tire pressure.
The CHECK TIRE PRESSURE Warning is
active as long as the low tire pressure
warning light remains illuminated.
For additional information, see“Dot matrix
liquid crystal display” (P.2-17),“Tire Pres-
sure Monitoring System (TPMS)” (P.5-4)
and “Tire Pressure Monitoring System
(TPMS)” (P.6-2).
TPMS malfunction:
GUID-D73A39BF-43C8-459F-9C24-47B7F579C407If the TPMS is not functioning properly, the
low tire pressure warning light will flash for
approximately 1 minute when the ignition
switch is pushed ON. The light will remain
on after 1 minute. Have the system
checked by an INFINITI retailer. The CHECK
TIRE PRESSURE warning does not appear if
the low tire pressure warning light illumi-
nates to indicate a TPMS malfunction.
For additional information, see “Tire Pres-
sure Monitoring System (TPMS)” (P.5-4).
WARNING
.If the light does not illuminate with the
ignition switch pushed ON, have the vehicle checked by an INFINITI retailer as
soon as possible.
. If the light illuminates while driving,
avoid sudden 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 in-
crease 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. If you have a flat tire,
replace it with a spare tire as soon as
possible.
. 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 the 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.
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.

HOW TO PARK WITH PREDICTED
COURSE LINES
GUID-CAF0F865-CEBD-48A9-9D4B-E5FF3C8B14DE
WARNING
. Always turn and check that it is safe to
park your car before backing up. Always
back up slowly.
. Use the displayed lines as a reference.
The lines are highly affected by the
number of occupants, fuel level, vehicle
position, road condition and road grade.
. If the tires are replaced with different
sized tires, the predicted course line
may not be displayed correctly. .
On a snow-covered or slippery road,
there may be a difference between the
predicted course line and the actual
course line.
. If the battery is disconnected or be-
comes discharged, the predicted course
lines may be displayed incorrectly. If this
occurs, drive the vehicle on a straight
road for more than 5 minutes.
. The displayed lines will appear slightly
off to the right because the rearview
camera is not installed in the rear center
of the vehicle.
. The distance guide line and the vehicle
width guide line should be used as a
reference only when the vehicle is on a
level paved surface. The distance viewed
on the monitor is for reference only and
may be different than the actual distance
between the vehicle and displayed ob-
jects.
. When backing up the vehicle up a hill,
objects viewed in the monitor are further
than they appear. When backing up the
vehicle down a hill, objects viewed in the
monitor are closer than they appear. Use
the inside mirror or glance over your
shoulder to properly judge distances to other objects.
The vehicle width and predicted course
lines are wider than the actual width and
course.

How to handle the sensorGUID-987C621F-BCC5-4DA7-BA01-D4D917899DCAThe sensor for the Preview Function is
common with Intelligent Cruise Control and
is located below the front bumper.
To keep the Preview Function operating
properly, 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 da-
maged due to an accident, contact an

accessory near the sensor. This could
cause failure or malfunction.
ANTI-LOCK BRAKING SYSTEM (ABS)GUID-CC021868-0ABC-45AA-B3D9-819FB93AA13F
WARNING
. The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless or
dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remember
that stopping distances on slippery
surfaces will be longer than on normal
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
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 “Tireand Loading Information label”
(P.9-
13) of this manual.
—For detailed information, see “Wheels and tires” (P.8-30) of this
manual.
The Anti-lock Braking System (ABS) con-
trols 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 pre-
venting each wheel from locking, the
system helps the driver maintain steering
control and helps to minimize swerving
and spinning on slippery surfaces.
Using the systemGUID-A17A02B4-B98C-49CB-8417-28E29F497208Depress 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.

. If wheels or tires other than the INFINITI
recommended ones are used, the VDC
system may not operate properly and
the VDC warning light
may illumi-
nate.
. The VDC system is not a substitute for
winter tires or tire chains on a snow
covered road.

FREEING A FROZEN DOOR LOCKGUID-2C882469-11A3-4715-8BCB-FA19FFE0887FTo 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.
ANTIFREEZEGUID-C3261124-A271-4B19-A25E-63CCB5008F6AIn the winter when it is anticipated that the
outside temperature will drop below 328F
(08C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system” (P.8-8).
BATTERYGUID-F9CBEBD7-C133-422D-A36C-05EFDC8A701EIf the battery is not fully charged during
extremely 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”
(P.8-15).
DRAINING OF COOLANT WATERGUID-52E88C59-7722-46BD-A12A-8762FEB37D9CIf the vehicle is to be left outside without
antifreeze, drain the cooling system, in-
cluding the engine block. Refill before
operating the vehicle. For details, see
“Engine cooling system” (P.8-8).
TIRE EQUIPMENTGUID-A19A4B63-2858-43F2-970D-016811637FE9SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. 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 prohi-
bit 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”(P.8-37) of this manual.

GUID-4DADA991-350E-4791-AC1F-B7D348E957C5Additional information on the following
items with “*”is found later in this
section.
Outside the vehicleGUID-935F9711-28E8-44B7-926E-055C6CC77282The maintenance items listed here should
be performed from time to time, unless
otherwise specified.
Doors and engine hood: Check that all
doors and the engine hood operate prop-
erly. Also ensure that all latches lock
securely. Lubricate hinges, latches, latch
pins, rollers and links if necessary. Make
sure that the secondary latch keeps the
hood from opening when the primary latch is released.
When driving in areas using road salt or
other corrosive materials, check lubrication
frequently.
Lights*:
Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and
other lights are all operating properly and
installed securely. Also check headlight
aim.
Road wheel nuts (lug nuts)*: When check-
ing the tires, make sure no wheel nuts are
missing, and check for any loose wheel
nuts. Tighten if necessary.
Tire rotation*: Tires cannot be rotated, as
front tires are a different size from rear
tires and the direction of wheel rotation is
fixed in each tire.
Tires*: Check the pressure with a gauge
often and always prior to long distance
trips. If necessary, adjust the pressure in
all tires, including the spare, to the
pressure specified. Check carefully for
damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the TPMS
transmitter grommet seal, valve core and
cap when the tires are replaced due to wear or age.
Tire, wheel alignment and balance:
If the
vehicle should pull to either side while
driving on a straight and level road, or if
you detect uneven or abnormal tire wear,
there may be a need for wheel alignment.
If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing
may be needed.

TYPES OF TIRESGUID-0F3309CD-2C8B-4C37-9605-B2B74CF8D48F
WARNING
.When changing or replacing tires, be
sure all four tires are of the same type
(Example: Summer, All Season or Snow)
and construction. An INFINITI retailer
may be able to help you with information
about tire type, size, speed rating and
availability.
. Replacement tires may have a lower
speed rating than the factory equipped
tires, and may not match the potential
maximum vehicle speed. Never exceed
the maximum speed rating of the tire.
. Replacing tires with those not originally specified by INFINITI could affect the
proper operation of the TPMS.
. For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or“Tire Safety Infor-
mation” (Canada) in the Warranty Infor-
mation Booklet.
All season tiresGUID-AA383A95-D373-488B-A8E8-CDBF6791B263INFINITI specifies all season tires on some
models to provide good performance all
year, including snowy and icy road condi-
tions. All Season tires are identified by ALL
SEASON and/or M&S (Mud and Snow) on
the tire sidewall. Snow tires have better
snow traction than All Season tires and
may be more appropriate in some areas.
Summer tiresGUID-B04DEE83-96EC-4740-BF40-CCAB483BBE93INFINITI specifies summer tires on some
models to provide superior performance on
dry roads. Summer tire performance is
substantially reduced in snow and ice.
Summer tires do not have the tire traction
rating M&S on the tire sidewall.
If you plan to operate your vehicle in snowy
or icy conditions, INFINITI recommends the
use of SNOW tires or ALL SEASON tires on all four wheels.
Snow tiresGUID-F39DC593-D9CC-4031-A698-A6D6CC4F8C92If snow tires are needed, it is necessary to
select tires equivalent in size and load
rating to the original equipment tires. If
you do not, it can adversely affect the
safety and handling of your vehicle.
Generally, snow tires will have lower speed
ratings than factory equipped tires and
may not match the potential maximum
vehicle speed. Never exceed the maximum
speed rating of the tire.
If you install snow tires, they must be the
same size, brand, construction and tread
pattern on all four wheels.
For additional traction on icy roads,
studded tires may be used. However, some
U.S. states and Canadian provinces prohi-
bit 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 CHAINSGUID-6A88FBD9-125B-4B3A-A7FE-FA86DDB25535Use of tire chains may be prohibited
according to location. Check the local laws
before installing tire chains. When instal-
ling tire chains, make sure they are the
proper size for the tires on your vehicle and
are installed according to the chain man-
ufacturer’s suggestions.Use only SAE
Class S chains. Class“S”chains are used
on vehicles with restricted tire to vehicle
clearance. Vehicles that can use Class “S”
chains are designed to meet the SAE
standard minimum clearances between
the tire and the closest vehicle suspension
or body component required to accommo-
date the use of a winter traction device (tire
chains or cables). The minimum clearances
are determined using the factory equipped
tire size. Other types may damage your
vehicle. Use chain tensioners when recom-
mended by the tire chain manufacturer to
ensure a tight fit. Loose end links of the
tire chain must be secured or removed to
prevent the possibility of whipping action
damage to the fenders or underbody. If
possible, avoid fully loading your vehicle
when using tire chains. In addition, drive at
a reduced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling and performance may be adversely af-
fected.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Never install tire chains on a TEMPORARY
USE ONLY spare tire.
Do not use tire chains on dry roads. Driving
with tire chains in such conditions can
cause damage to the various mechanisms
of the vehicle due to some overstress.

WARNING
.Tires should be periodically in-
spected for wear, cracking, bul-
ging or objects caught in the
tread. If excessive wear, cracks,
bulging or deep cuts are found,
the tire(s) should be replaced. .
The original tires have built-in

indicators are visible, the tire(s)
should be replaced.
. Tires degrade with age and use.
Have tires, including the spare,
over 6 years old checked by a
qualified technician, because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.
. Improper service of the spare tire
may result in serious personal
injury. If it is necessary to repair
the spare tire, contact an INFINITI
retailer.
. For additional information regard-
ing tires, refer to “Important Tire

Replacing wheels and tiresGUID-9715A1ED-EE7A-41C8-9DA9-0A2EB272D8BAWhen replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. (See
“Specifications” (P.9-8) for recommended
types and sizes of tires and wheels.)
WARNING
. The use of tires other than those
recommended or the mixed use of tires
of different brands, construction (bias,
bias-belted or radial), or tread patterns
can adversely affect the ride, braking,
handling, ground clearance, body-to-tire
clearance, tire chain clearance, speed-
ometer calibration, headlight aim and
bumper height. Some of these effects
may lead to accidents and could result in
serious personal injury.
. If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimension.
Wheels of a different off-set could cause
premature tire wear, degrade vehicle
handling characteristics and/or interfer-
ence with the brake discs/drums. Such
interference can lead to decreased brak-
