9-10Maintenance and Schedules

level roads, it is recommended you have an
INFINITI retailer correct the condition. Failure to
correct the condition is misuse of the vehicle, for
which INFINITI is not responsible.
Incorrect ignition timing will result in knocking,
after-run and/or overheating. This in turn may
cause excessive fuel consumption or damage to
the engine. If any of the above symptoms are
encountered, have your vehicle checked. It is
recommended you visit an INFINITI retailer.
However, now and then you may notice light
spark knock for a short time while accelerating
or driving up hills. This is no cause for concern,
because you get the greatest fuel benefit when
there is light spark knock for a short time under
heavy engine load.

ENGINE OIL AND OIL FILTER
RECOMMENDATIONS
Selecting the correct oil
It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure sat-
isfactory engine life and performance. For addi-
tional information, refer toRecommended
fluids/lubricants and capacities earlier in this
section. INFINITI recommends the use of an
energy conserving oil in order to improve fuel
economy.
Select only engine oils that meet the American
Petroleum Institute (API) certification or Interna-
tional Lubricant Standardization and Approval Committee (ILSAC) certification and SAE viscos-
ity standard. These oils have the API certifica-
tion mark on the front of the container. Oils
which do not have the specified quality label
should not be used as they could cause engine
damage.
Oil additives
INFINITI does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used and
maintenance intervals are followed.
Oil which may contain foreign matter or has
been previously used should not be used.
Oil viscosity
The engine oil viscosity or thickness changes
with temperature. Because of this, it is impor-
tant that the engine oil viscosity be selected
based on the temperatures at which the vehicle
will be operated before the next oil change.
Choosing an oil viscosity other than that recom-
mended could cause serious engine damage.
Selecting the correct oil filter
Your new vehicle is equipped with a high—
quality genuine INFINITI oil filter. When replac-
ing, it is recommended you use the genuine oil
filter or its equivalent for the reason described
in “Change intervals”.

Technical information10-5

For Canada:
If you believe that your vehicle has a defect
which could cause a crash or could cause injury
or death, you should immediately inform Trans-
port Canada in addition to notifying INFINITI.
If Transport Canada receives complaints, it may
open an investigation, and if it finds that a
safety defect exists in a group of vehicles, it
may request that INFINITI conduct a recall cam-
paign. However, Transport Canada cannot be-
come involved in individual problems between
you, your retailer, or INFINITI.
You may contact Transport Canada’s Defect
Investigations and Recalls Division toll free at
1-800-333- 0510. You may also report safety
defects online at:
https://wwwapps.tc.gc.ca/Saf-Sec- Sur/7/
PCDB-BDPP/Index.aspx.
Additional information concerning motor ve-
hicle safety may be obtained from Transport
Canada’s Road Safety Information Center at
1-800-333- 0371 or online at www.tc.gc.ca/
roadsafety (English speakers) or www.tc.gc.ca/
securiteroutiere (French speakers).
To notify INFINITI of any safety concerns please
contact our Consumer Information Center toll
free at 1-800- 361-4792.WARNING
A vehicle equipped with All-Wheel Drive (AWD)
should never be tested using a two wheel dy-
namometer (such as the dynamometers used
by some states for emissions testing), or simi-
lar equipment. Make sure you inform test facil-
ity personnel that your vehicle is equipped
with AWD before it is placed on a dynamom-
eter. Using the wrong test equipment may re-
sult in transmission damage or unexpected ve-
hicle movement which could result in serious
vehicle damage or personal injury.
Due to legal requirements in some states and
Canadian Provinces, your vehicle may be re-
quired to be in what is called the “ready
condition” for an Inspection/Maintenance (I/M)
test of the emission control system.
The vehicle is set to the “ready condition” when
it is driven through certain driving patterns.
Usually, the “ready condition” can be obtained
by ordinary usage of the vehicle.
If a powertrain system component is repaired or
the battery is disconnected, the vehicle may be
reset to a “not ready condition”. Before taking
the I/M test, check the vehicle’s inspection/
maintenance test readiness condition. Place the
ignition switch in the ON position without start- ing the engine. If the Malfunction Indicator Light
(MIL) comes on steady for 20 seconds and then
blinks for 10 seconds, the I/M test condition is
“not ready”. If the MIL does not blink after 20
seconds, the I/M test condition is “ready”.
It is recommended you contact an INFINITI re-
tailer to set the “ready condition” or to prepare
the vehicle for testing.

knee air bag will deflate quickly after the collision
is over OR the knee air bag will remain inflated for
a short time.
The knee air bags operate only when the
ignition switch is placed in the ON position.
After placing the ignition switch in the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off a few seconds
after the engine starts if the system is op-
erational.
WARNING
●Do not place any objects between the
knee bolster and the driver’s seat. Such
objects may become dangerous projec-
tiles and cause injury if a knee air bag
inflates.
● Right after inflation, the knee 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 knee air bag system. This is to pre-
vent damage to or accidental inflation
of the knee air bag system. ●
Do not make unauthorized changes to
your vehicle’s electrical system or sus-
pension system. This could affect
proper operation of the knee air bag
system.
● Tampering with the knee air bag system
may result in serious personal injury.
For example, do not change the driver
knee bolster or install additional trim
material around the knee air bag.
● It is recommended that you visit an
INFINITI retailer for work on and around
the knee air bag. It is also recom-
mended that you visit an INFINITI re-
tailer for installation of electrical equip-
ment. The SRS wiring harnesses*
should not be modified or discon-
nected. Unauthorized electrical test
equipment and probing devices should
not be used on the knee air bag system.
*The SRS wiring harness or connectors
are yellow or orange for easy
identification.
When selling your vehicle, we request that you
inform the buyer about the knee air bag system
and guide the buyer to the appropriate sections
in this manual.
Seat belt with pretensioner(s)
WARNING
● The pretensioner(s) cannot be reused
after activation. They must be replaced
together with the retractor and buckle
as a unit.
● If the vehicle becomes involved in a
collision but pretensioner(s) are not ac-
tivated, be sure to have the preten-
sioner system checked and, if neces-
sary, replaced. It is recommended that
you visit an INFINITI retailer for this
service.
● No unauthorized changes should be
made to any components or wiring of
the pretensioner system. This is to pre-
vent damage to or accidental activation
of the pretensioner(s) . Tampering with
the pretensioner system may result in
serious personal injury.

SUPPLEMENTAL AIR BAG
WARNING LIGHT
The supplemental air bag warning light,
displaying
in the instrument panel, moni-
tors the circuits for the air bag systems, preten-
sioner(s) and all related wiring.
When the ignition switch is placed in the ON
position, the supplemental air bag warning light
illuminates. The air bag warning light will turn off
within a few seconds after the engine is started, if
the system is operational. If any of the following conditions occur, the front
air bag, side air bag, curtain air bag and preten-
sioner systems need servicing:
● 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.
Under these conditions, the front air bag, side air
bag, curtain air bag, knee air bag or pretensioner
systems may not operate properly. They must be
checked and repaired. It is recommended that
you visit an INFINITI retailer for this service.
WARNING
If the supplemental air bag warning light
is on, it could mean that the front air bag,
side air bag, knee air bag, curtain air bag
and/or pretensioner systems will not op-
erate in an accident. To help avoid injury to
yourself or others, have your vehicle
checked as soon as possible. It is recom-
mended that you visit an INFINITI retailer
for this service.
