INDICATORS FOR MAINTENANCE
1. Engine oil replacement indicator
This indicator appears when the customer
set time comes for changing the engine oil.
You can set or reset the distance for
changing the engine oil. (See “Trip compu-
ter” (P.2-26).)
2. Oil filter replacement indicator
This indicator appears when the customer
set time comes for replacing the oil filter.
You can set or reset the distance for
replacing the oil filter. (See “Trip compu-
ter” (P.2-26).)
3. Tire replacement indicator
This indicator appears when the customer
set distance comes for replacing tires. You
can set or reset the distance for replacing
tires. (See “Trip computer” (P.2-26).)
WARNING
The tire replacement indicator is not a
substitute for regular tire checks, including
tire pressure checks. See “Changing wheels
and tires” (P.8-37). Many factors including
tire inflation, alignment, driving habits and

road conditions affect tire wear and when
tires should be replaced. Setting the tire
replacement indicator for a certain driving
distance does not mean your tires will last
that long. Use the tire replacement indicator
as a guide only and always perform regular
tire checks. Failure to perform regular tire
checks, including tire pressure checks could
result in tire failure. Serious vehicle damage
could occur and may lead to a collision,
which could result in serious personal injury
or death.
4.“OTHER” indicator
This indicator appears when the customer
set time comes for replacing items other
than the engine oil, oil filter and tires. You
can set or reset the distance for replacing
the items. (See “Trip computer” (P.2-26).)

headlights. Failure to do so could cause an
accident injuring yourself and others.
Adaptive Front lighting System
(AFS) (if so equipped)
The Adaptive Front lighting System (AFS)
will automatically adjust the headlights
(low beam) toward the turning direction to
improve the driver’s view. When the head-
light switch is ON and the driver operates
the steering wheel in a turn, the AFS
system will be activated.
The AFS will operate:
.when the headlight switch is ON.
. when the shift lever is in any position
other than P (Park) or R (Reverse).
. when the vehicle is driven at above 16
MPH (25 km/h) for the left-side head-
light. Note that the right-side low beam
headlight will swivel but the left side
will not swivel when the vehicle is at a
stop and the steering wheel is turned.
The vehicle must attain a speed above
16 MPH (25 km/h) before AFS activates
the left-side headlight.
AFS will also adjust the headlight to a
proper axis automatically, depending on
the number of occupants in the vehicle, the load the vehicle is carrying and the road
conditions.
If the AFS OFF indicator light blinks after
the ignition switch has been pushed to the
ON position, this may indicate that the AFS
is not functioning properly. Have the
system checked by an INFINITI retailer.
When the engine is started, the headlights
will vibrate to check the system condition.
This is not a malfunction.

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 elec-
trical systems 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 retai-
ler.
. 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 SYS-
TEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended 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 pressure 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 your tires as soon as
possible, and inflate them to the proper
pressure. 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 com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously
illuminated. This sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the mal-
function indicator is illuminated, the sys-
tem may not be able to detect or signal low
tire pressure as intended. TPMS malfunc-
tions 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 prop-
erly. 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.
