PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612893
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
Precaution for Procedur e without Cowl Top CoverINFOID:0000000001612894
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Handling for Adhesive and PrimerINFOID:0000000001327954
 Do not use an adhesive which is past its usable date. Shel f life of this product is limited to six months after
the date of manufacture. Carefully adhere to the ex piration or manufacture date printed on the box.
 Keep primers and adhesive in a cool, dry place. I deally, they should be stored in a refrigerator.
 Open the seal of the primer and adhesive just before application. Discard the remainder.
 Before application, be sure to shake the primer container to stir the contents. If any floating material is found,
do not use it.
 If any primer or adhesive contacts the skin, wipe it off with gasoline or equivalent and wash the skin with
soap.
 When using primer and adhesive, always observe the precautions in the instruction manual.

General Precaution for Service OperationINFOID:0000000001328264
 Never work with wet hands.
 Xenon headlamp includes high voltage generating part. Be sure to disconnect battery negative cable (negative terminal) or power
fuse before removing, installing, or touching the xenon headlamp
(including lamp bulb).
 Turn the lighting switch OFF before disconnecting and connecting the connector.
 When turning the xenon headlamp on and while it is illuminated, never touch the harness, bulb, and socket of the headlamp.
 When checking the headlamp on/off operation, check it on vehicle
and with the power connected to the vehicle-side connector.
 Do not touch the headlamp bulb glass surface with bare hands or allow oil or grease to get on it. Do not touch the headl amp bulb just after the headlamp is turned off, because
it is very hot.
 Install the xenon headlamp bulb socket co rrectly. If it is installed improperly, high-voltage leak or corona dis-
charge may occur that can melt the bulb, connecto r, and housing. Do not illuminate the xenon headlamp
bulb out of the headlamp housing. Doing so can cause fire and harm your eyes.
 When the bulb has burned out, wrap it in a thick vinyl bag and discard. Do not break the bulb.
 Leaving the bulb removed from the headlamp housing for a long period of time can deteriorate the perfor- mance of the lens and reflector (dirt, clouding). Al ways prepare a new bulb and have it on hand when replac-
ing the bulb.
 When adjusting the headlamp aiming, turn the aiming adjus tment screw only in the tightening direction. (If it
is necessary to loosen the screw, first fully loosen the screw, and then turn it in the tightening direction.)
 Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.

VEHICLE SECURITY SYSTEM

XENON HEADLAMP
Xenon type lamps are used for to the low beam headlamps . Xenon bulbs do not use a filament. Instead, they
produce light when a high voltage current is passed between two tungsten electrodes through a mixture of
xenon (an inert gas) and certain other metal halides. In addition to strong lighting power, electronic control of
the power supply gives the headlamps stable quality and tone color.
Followings are some advantages of the xenon type headlamp.
 The light produced by the headlamps is white color si milar to sunlight that is easy to the eyes.
 Light output is nearly double that of halogen headl amps, affording increased area of illumination.
 Counter-reflected luminance increases and the contrast enhances on the wet road in the rain. That makes
visibility go up more than the increase of the light volume.
 Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.
CAN Communication System DescriptionINFOID:0000000001328267
CAN (Controller Area Network) is a serial communication li ne for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

*1: For further details, see “Engine Oil Recommendation”.
*2: Using automatic transmission fluid other than Genuine NISSAN Matic J ATF will cause deterioration in driveability and
automatic transmission durability, and may damage the automatic transmission, which is not covered by the INFINITI new
vehicle limited warranty.
*3: For hot climates, viscosity SAE 90 is suitable for ambient temperatures above 0 °C (32 °F).
*4: Canada NISSAN Au tomatic Transmission Fluid or DEXRON
TM VI type ATF may also be used.
*5: Available in mainland U.S.A. through your INFINITI dealer.
Engine Oil RecommendationINFOID:0000000001328898
NISSAN recommends the use of an energy conser ving oil in order to improve fuel economy.
Select only engine oils that meet the American Petroleum Institute (API) certification and International Lubri-
cant Standardization and Approval Committee (ILSAC) certification and SAE viscosity standard. These oils
have the API certification mark on the front of the c ontainer. Oils which do not have the specified quality label
should not be used as they could cause engine damage.
