RAIN-SENSING AUTO WIPER
SYSTEM
The rain-sensing auto wiper system can
automatically turn on the wipers and adjust
the wiper speed depending on the rainfall
and the vehicle speed by using the rain
sensor located on the upper part of the
windshield.
To set the rain-sensing auto wiper system,
push the lever down to the AUTO position
. The wiper will sweep once while the
ignition switch is in the ON position.
The rain sensor sensitivity level can be
adjusted by turning the knob toward the
front
(High) or toward the rear(Low). .
High — High sensitive operation
. Low — Low sensitive operation
To turn the rain-sensing auto wiper system
off, push up the lever to the OFF position, or
pull down the lever to the LO or HI position.
CAUTION
Do not touch the rain sensor and around
it when the wiper switch is in the AUTO
position and the ignition switch is in the
ON position. The wipers may operate
unexpectedly and cause to an injury or
may damage a wiper.
. The rain-sensing auto wipers are in-
tended for use during rain. If the switch
is left in the AUTO position, the wipers
may operate unexpectedly when dirt,
fingerprints, oil film or insects are stuck
on or around the sensor. The wipers may
also operate when exhaust gas or
moisture affect the rain sensor.
. The rain-sensing auto wipers may not
operate if rain does not hit the rain
sensor even if it is raining.
. When the windshield glass is coated
with water repellent, the speed of the
rain-sensing auto wipers may be higher
even though the amount of the rainfall is
small. .
Be sure to turn off the rain-sensing auto
wiper system when you use a car wash.
. When the ignition switch is in the ON
position and the vehicle speed is below
approximately 5 MPH (8 km/h) with
the shift lever in the N (Neutral) posi-
tion, the rain-sensing auto wipers will
not operate.
. Using genuine wiper blades is recom-
mended for proper operation of the
rain-sensing auto wiper system. (See
“Windshield wiper blades” (P.8-15) for
wiper blade replacement.)

Flicker image (example)
. When LED headlights are viewed on the
Smart Rearview Mirror display, the
images may flicker. This is normal.
. Due to diffused reflection from external
environment, images on the screen may
flicker. This is not a malfunction.
. A quick movement of a thing may not be
able to display on the camera view
screen. This is not a malfunction.
. Turn on the headlights at twilight or in a
tunnel, etc.
. The Smart Rearview Mirror mode (cam-
era view mode) display is different from
the conventional rearview mirror. Ob-
jects in the display may differ from actual distance. Do not solely rely on
the Smart Rearview Mirror. Always rely
on your own operation to avoid acci-
dents.
. If the brightness of the camera view
display is adjusted to excessive bright
level, it may cause an eyestrain in the
driving. Adjust the brightness properly.
. Use the rear window wiper when it rains.
If the camera view image is still unclear
when the rear window wiper is in
operation, check the deterioration of
the rear window wiper blade.
. When using the rear window wiper,
images on the screen may flicker. This
is not a malfunction.
. Defog the rear window with defroster
when rear window is fogged. Use the
conventional rearview mirror mode until
the rear window is fully defogged.
. The display of the Smart Rearview
Mirror may become hot. This is not a
malfunction.
. The color of an object in the distance or
in the dark may be difficult to be
recognized. This is not a malfunction.
System maintenance (Smart Rearview

ENGINE PROTECTION MODE
The engine has an engine protection mode to
reduce the chance of damage if the coolant
temperature becomes too high (for example,
when climbing steep grades in high tem-
perature with heavy loads, such as when
towing a trailer).
When the engine temperature reaches a
certain level:
.The engine coolant temperature gauge
will move toward the H position.
. Engine power may be reduced.
. The air conditioning cooling function may
be automatically turned OFF for a short
time (the blower will continue to oper-
ate).
Engine power and, under some conditions,
vehicle speed will decrease. Vehicle speed
can be controlled with the accelerator pedal,
but the vehicle may not accelerate at the
desired speed. The transmission will down-
shift or upshift as it reaches prescribed shift
points. You can also shift manually.
As driving conditions change and engine
coolant temperature is reduced, vehicle
speed can be increased using the accelerator
pedal, and air conditioning cooling function
will automatically be turned back ON. If:
1. The engine coolant temperature is not
reduced.
2. The air conditioning cooling function does not turn back ON.
3. The engine oil pressure warning light
illuminates or engine coolant tempera-
ture gauge does not return to the normal
range from the H position, this may
indicate a malfunction. Move the vehicle
off the road to a safe area and allow the
engine to cool. If after checking the oil
and coolant, the
remains on or
engine coolant temperature does not
return to the normal range, do not
continue to drive. It is recommended
you contact an INFINITI retailer.
The Malfunction Indicator Light (MIL)
may also come ON. You do not need to have
your vehicle towed, unless it remains on, but
have it inspected soon. It is recommended
you visit an INFINITI retailer for this service.
See “Warning lights, indicator lights and
audible reminders” (P.2-11).
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced
speed may be lower than other traffic, which could increase the chance of a
collision. Be especially careful when
driving. If the vehicle cannot maintain a
safe driving speed, pull to the side of the
road in a safe area. Allow the engine to
cool and return to normal operation. See
“If your vehicle overheats” (P.6-14).
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not cov-
ered by warranty. Turn off the engine as
soon as it is safe to do so.
