Front passenger air bag
status light
The front passenger air bag status lightwill be lit and the passenger front air
bag will be off depending on how the front
passenger seat is being used.
For additional information, refer to “Front
passenger air bag and status light” in the
“Safety — Seats, seat belts and supplemen-
tal restraint system” section of this manual.
High beam indicator light
(blue)
This blue light comes on when the head-
light high beams are on and goes out when
the low beams are selected.
The high beam indicator light also comes
on when the passing signal is activated.
Hill descent control system
ON indicator light (if so
equipped)
When the ignition switch is placed in the ON
position, this light comes on briefly and
then turns off.
The light comes on when the hill descent
control system is activated. If the hill descent control switch is on and
the indicator light blinks, the system is not
engaged.
If the indicator light does not come on
when the hill descent switch is on, the sys-
tem may not be functioning properly. Have
the system checked. It is recommended
that you visit a NISSAN dealer for this ser-
vice.
For additional information, refer to “Hill de-
scent control switch” in this section and “Hill
descent control system” in the “Starting
and driving” section of this manual.
Malfunction Indicator Light
(MIL)
If this indicator light comes on steady or
blinks while the engine is running, it may
indicate a potential emission control mal-
function.
The MIL may also come on steady if the
fuel-filler cap is loose or missing, or if the
vehicle runs out of fuel. Check to make sure
the fuel-filler cap is installed and closed
tightly, and that the vehicle has at least 3
gal (11.4 L) of fuel in the fuel tank.
Af ter a few driving trips, the
light
should turn off if no other potential emis-
sion control system malfunction exists. If this indicator light comes on steady for 20
seconds and then blinks for 10 seconds
when the engine is not running, it indicates
that the vehicle is not ready for an emission
control system inspection/maintenance
test. For additional information, refer to
“Readiness for inspection/maintenance
(I/M) test” in the “Technical and consumer
information” section of this manual.
Operation
The MIL will come on in one of two ways:
• MIL on steady — An emission control sys-
tem malfunction has been detected.
Check the fuel-filler cap if the LOOSE FUEL
CAP warning appears in the trip com-
puter. If the fuel-filler cap is loose or miss-
ing, tighten or install the cap and con-
tinue to drive the vehicle. The
light
should turn off af ter a few driving trips. If
the
light does not turn off af ter a few
driving trips, have the vehicle inspected. It
is recommended that you visit a NISSAN
dealer for this service. You do not need to
have your vehicle towed to the dealer.
• MIL blinking — An engine misfire has been detected which may damage the emis-
sion control system. To reduce or avoid
emission control system damage:– Do not drive at speeds above 45 mph (72 km/h).

4-12Monitor, climate, audio, phone and voice recognition systems

•Objects viewed in the RearView
Monitor differ from actual distance
because a wide-angle lens is used.
• Objects in the RearView Monitor will
appear visually opposite compared
to when viewed in the rearview and
outside mirrors.
• Use the displayed lines as a refer-
ence. The lines are highly affected by
the number of occupants, fuel level,
vehicle position, road conditions and
road grade.
• Make sure that the tailgate is se-
curely closed when backing up.
• Do not put anything on the rearview
camera. The rearview camera is in-
stalled on the tailgate.
• When washing the vehicle with high
pressure water, be sure not to spray it
around the camera. Otherwise, water
may enter the camera unit causing
water condensation on the lens, a
malfunction, fire or an electric shock.
• Do not strike the camera. It is a preci-
sion instrument. Otherwise, it may
malfunction or cause damage result-
ing in a fire or an electric shock. The following are operating limitations and
do not represent a system malfunction:
• When the temperature is extremely high
or low, the screen may not clearly display
objects.
• When strong light directly shines on the camera, objects may not be displayed
clearly.
• Vertical lines may be seen in objects on the screen. This is due to strong reflected
light from the bumper.
• The screen may flicker under fluorescent light.
• The colors of objects on the RearView Monitor may differ somewhat from the
actual color of objects.
• Objects on the monitor may not be clear in a dark environment.
• There may be a delay when switching between views.
• If dirt, rain or snow accumulate on the camera, RearView Monitor may not dis-
play objects clearly. Clean the camera.
• Do not use wax on the camera lens. Wipe off any wax with a clean cloth dampened
with a diluted mild cleaning agent, then
wipe with a dry cloth.
SYSTEM MAINTENANCE
LHA3671

THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst
are burned at high temperatures to help
reduce pollutants.
CAUTION
• Do not use leaded gasoline. Deposits
from leaded gasoline will seriously
reduce the three-way catalyst's abil-
ity to help reduce exhaust pollutants. •
Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical 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 no-
ticeable loss of performance or other
unusual operating conditions are de-
tected. Have the vehicle inspected
promptly. It is recommended that
you visit a NISSAN dealer for this
service.
• Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three-way catalyst.
• Do not race the engine while warm-
ing it up.
• Do not push or tow your vehicle to
start the engine.
TIRE PRESSURE MONITORING
SYSTEM (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 pos-
sible, and inflate them to the proper pres-
sure. 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 substi-
tute for proper tire maintenance, and it is
the driver’s responsibility to maintain cor-
rect tire pressure, even if under-inflation
has not reached the level to trigger illumi-
nation 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,
