Lane Departure Prevention (LDP) system”
(P.5-30), “Blind Spot Warning/Blind Spot Intervention
TM/Back-up Collision Interven-
tion systems” (P.5-37),“Distance Control
Assist (DCA) system” (P.5-79),“Forward
emergency braking system” (P.5-89) and
“Predictive forward collision warning sys-
tem” (P.5-94).
Power steering warning light
(if so equipped)
When the ignition switch is in the ON
position, the power steering warning light
illuminates. After starting the engine, the
power steering warning light turns off. This
indicates that Direct Adaptive Steering is
operational.
If the power steering warning light illumi-
nates while the engine is running, it may
indicate Direct Adaptive Steering is not
functioning properly and may need servi-
cing. Have Direct Adaptive Steering
checked by an INFINITI retailer. (See “Direct
Adaptive Steering type” (P.5-104).)
Seat belt warning light and
chime
The light and chime remind you to fasten
seat belts. The light illuminates whenever
the ignition 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
passenger will illuminate if the seat belt is
not fastened when the front passenger’s
seat is occupied.
See
“Seat belts” (P.1-12) 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 supplemental front air bag
and supplemental side air bag, curtain
side-impact air bag systems and/or pre-
tensioner seat belt are operational.
If any of the following conditions occur, the
supplemental front air bag, supplemental

impact air bag and pretensioner seat belt
needs servicing and your vehicle must be
taken to your nearest INFINITI retailer.
. The supplemental air bag warning light
remains on after approximately 7 sec-

3-22Pre-driving checks and adjustments
.Push the power door lock switch to the
UNLOCK position.
To lock, close the fuel-filler door securely
and lock all doors by operating the door
handle request switch, the LOCK button on
the Intelligent Key, the mechanical key or
the power door lock switch.
FUEL-FILLER CAP
WARNING
. Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seriously
injured if it is misused or mishandled.
Always stop engine and do not smoke or
allow open flames or sparks near the
vehicle when refueling.
. Do not attempt to top off the fuel tank
after the fuel pump nozzle shuts off
automatically. Continued refueling may
cause fuel overflow, resulting in fuel
spray and possibly a fire.
. Use only an original equipment type
fuel-filler cap as a replacement. It has a
built-in safety valve needed for proper
operation of the fuel system and emis-
sion control system. An incorrect cap can result in a serious malfunction and
possible injury. It could also cause the
Malfunction Indicator Light (MIL) to
come on.
. Never pour fuel into the throttle body to
attempt to start your vehicle.
. Do not fill a portable fuel container in
the vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable fuel
containers:
—Always place the container on the
ground when filling.
—Do not use electronic devices whenfilling.
—Keep the pump nozzle in contact
with the container while you are
filling it.
—Use only approved portable fuelcontainers for flammable liquid.
CAUTION
. If fuel is spilled on the vehicle body,
flush it away with water to avoid paint
damage.
. Insert the cap straight into the fuel-filler
tube, then tighten the fuel-filler cap until
a single click is heard. Failure to tighten
the fuel-filler cap properly may cause the
Malfunction Indicator Light (MIL) to
illuminate. If thelight illuminates
because the fuel-filler cap is loose or
missing, tighten or install the cap and
continue to drive the vehicle. The
light should turn off after a few driving
trips. If thelight does not turn off
after a few driving trips, have the vehicle
inspected by an INFINITI retailer.
. The Loose Fuel Cap warning will appear
if the fuel-filler cap is not properly
tightened. It may take a few driving
trips for the warning to be displayed.
Failure to tighten the fuel-filler cap
properly after the Loose Fuel Cap warn-
ing appears may cause the
Mal-
function Indicator Light (MIL) to
illuminate.

9-6Technical and consumer information
above symptoms are encountered, have
your vehicle checked at an INFINITI retailer
or other competent service facility.
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 RE-
COMMENDATION
Selecting the correct oil
It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance,
see“Capacities and recommended fuel/
lubricants” (P.9-2). 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) certifi-
cation or International Lubricant Standar-
dization and Approval Committee (ILSAC)
certification and SAE viscosity standard.
These oils have the API certification 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.
