WARNING
The tire replacement indicator is not a
substitute for regular tire checks, includ-
ing tire pressure checks. See “Changing
wheels and tires” (P.8-34). Many fac-
tors including tire inflation, alignment,
driving habits and road conditions affect
tire wear and when tires should bereplaced. 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 pres-
sure 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.

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
Mirror):
. Always keep the mirror and camera area
of the rear window clean. .
Clean the mirror and the camera lens
with a dry soft cloth.
. When cleaning the camera area of the
rear window, use a soft cloth dampened
with water and a neutral detergent. Then
dry it with a dry soft cloth.
. If the image on the Smart Rearview
Mirror display screen is still unclear even
after cleaning the camera area of the
rear window, an oil film may be adhering
to the rear window glass. Clean the rear
window glass with an oil film remover.
. Never use alcohol, benzine, thinner, or
any similar material to clean the mirror or
camera lens. It will cause a discoloration,
deterioration or a system malfunction.
. Do not attach a sticker (including trans-
parent material) on the camera area of
the rear window.
OUTSIDE MIRRORS

After step 3 is performed, when the ignition
switch is pushed without depressing the
brake pedal, the ignition switch position will
change to ACC.
NOTE:
. When the ignition switch is pushed to
the ACC or ON position or the engine is
started by the above procedures, the
Intelligent Key battery discharge indi-
cator appears on the vehicle information
display even if the Intelligent Key is
inside the vehicle. This is not a malfunc-
tion. To turn off the Intelligent Key
battery discharge indicator, touch the
ignition switch with the Intelligent Key
again.
. If the Intelligent Key battery discharge
indicator appears, replace the battery as
soon as possible. (See “Battery” (P.8-

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.

8. Buy an automated pass for toll roads..Automated passes permit drivers touse special lanes to maintain cruising
speed through the toll and avoid
stopping and starting.
9. Winter warm up.
.Limit idling time to minimize impact to fuel economy.
.Vehicles typically need no more than30 seconds of idling at start-up to
effectively circulate the engine oil
before driving.
.Your vehicle will reach its ideal oper-ating temperature more quickly while
driving versus idling.
10. Keeping your vehicle cool.
.Park your vehicle in a covered parking area or in the shade whenever possi-
ble.
.When entering a hot vehicle, openingthe windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C system. .
Keep your engine tuned up.
. Follow the recommended scheduled
maintenance.
. Keep the tires inflated to the correct
pressure. Low tire pressure increases tire
wear and lowers fuel economy.
. Keep the wheels in correct alignment.
Improper alignment increases tire wear
and lowers fuel economy.
. Use the recommended viscosity engine
oil. (See “Engine oil and oil filter recom-
mendation” (P.10-6).)
WARNING
. Do not attempt to raise two wheels
off the ground and shift the trans-
mission to any drive or reverse posi-
tion with the engine running. Doing
so may result in drivetrain damage or
unexpected vehicle movement which
could result in serious vehicle damage
or personal injury.
. Do not attempt to test a 4WD
equipped vehicle on a 2-wheel dy-
namometer or similar equipment even
if the other two wheels are raised off
the ground. Make sure you inform
test facility personnel that your ve-
hicle is equipped with 4WD before it
is placed on a dynamometer. Using
the wrong test equipment may result
in drivetrain damage or unexpected
vehicle movement which could result
in serious vehicle damage or personal
injury.
CAUTION
.Do not drive the vehicle in the 4HI or
4LO position on dry hard surface
roads. Driving on dry, hard surfaces
INCREASING FUEL ECONOMYINFINITI ALL-MODE 4WD®(if so equipped)

5-124Starting and driving
The 4WD shift switch is used to select the
4WD mode depending on the driving condi-
tions. There are 3 types of drive modes
available, AUTO, 4HI and 4LO.
The 4WD shift switch electronically controls
the transfer case operation. Rotate the
switch to move between each mode, AUTO,
4H and 4L.
You must depress the 4WD shift switch to
select 4L, and the vehicle MUST be sta-
tionary and the shift lever in the N (Neutral)
position when changing into or out of 4L.
WARNING
.When parking, apply the parking
brake before stopping the engine
and make sure that the 4WD shift
indicator is on and the ATP warning
light turns off. Otherwise, the vehicle
could unexpectedly move even if the
automatic transmission is in the P
(Park) position.
. The 4LO and 4HI indicators must
stop blinking and the 4LO or 4HI
indicator must remain illuminated or
turn off before shifting the transmis-
sion into gear. If the shift lever is
shifted from the N (Neutral) position
to any other gear while the 4LO and
4HI indicators are blinking alter- nately, the vehicle may move unex-
pectedly.
CAUTION
.
Never shift the 4WD shift switch
between 4L and 4H while driving.
. The 4HI position provides greater
traction. Avoid excessive speed, as it
will cause increased fuel consumption
and higher oil temperatures, and
could damage drivetrain component.
Speeds over 62 MPH (100 km/h) in
4HI is not recommended.
. The 4LO position provides maximum
traction. Avoid raising vehicle speed
excessively, as the maximum speed is
approximately 31 MPH (50 km/h).
. When driving straight, shift the 4WD
shift switch to the AUTO or 4H
position. Do not move the 4WD shift
switch when making a turn or rever-
sing.
. Do not shift the 4WD shift switch
(between AUTO and 4H) while driv-
ing on steep downhill grades. Use the
engine brake and low automatic
transmission gears for engine brak-
ing. .
Do not operate the 4WD shift switch
(between AUTO and 4H) with the
rear wheels spinning.
. Do not drive on dry hard surface
roads in the 4HI or 4LO position.
Driving on dry hard surfaces in 4HI or
4LO may cause unnecessary noise
and tire wear. INFINITI recommends
driving in the AUTO position under
these conditions.
. The 4WD transfer case may not be
shifted between 4HI and 4LO at low
ambient temperatures and the 4LO
and 4HI indicators may blink even
when the 4WD shift switch is shifted.
After driving for a while you can
change the 4WD shift switch be-
tween 4H and 4L.
When driving on rough roads,
. Drive carefully according to the road
surface conditions.
When the vehicle is stuck,
. Place stones or wooden blocks under the
tires to free the vehicle.
. Set the 4WD shift switch to 4H or 4L.
. If it is difficult to free the vehicle, repeat
forward and backward movement to
increase the movement.

5-126Starting and driving
.Engine idling speed is high while
warming up the engine. Be especially
careful when starting or driving on
slippery surfaces with the 4WD shift
switch in AUTO.

4WD SHIFT INDICATOR
The 4WD shift indicator is displayed in the
vehicle information display.
The indicator should turn off within 1 second
after placing the ignition switch in the ON
position.
While the engine is running, the 4WD shift
indicator will illuminate the position selected
by the 4WD shift switch. (See the 4WD shift
procedure list shown in the “INFINITI all-
mode 4WD
®system” (P.5-121).)
. The 4WD shift indicator may blink while
shifting from one drive mode to the
other. When the shifting is completed, the 4WD shift indicator will come on. If
the indicator does not come on immedi-
ately, make sure the area around the
vehicle is safe, and drive the vehicle
straight, accelerate or decelerate or
move the vehicle in reverse, then shift
the 4WD shift switch.
. If the 4WD warning light comes on, the
4WD shift indicator turns off.
4WD WARNING LIGHT
Warning light Comes on or
blinks when:
Illuminates There is a mal-
function in the 4WD system
Blinks rapidly The transfer case
oil temperature is
abnormally high
Blinks slowly The difference in
wheel rotation is large
The 4WD warning light is located in the
meter.
The 4WD warning light comes on when the
ignition switch is placed in the ON position.
It turns off soon after the engine is started.
If any malfunction occurs in the 4WD system
when the ignition switch is placed in the ON
position, the 4WD warning light will either
remain illuminated or blink.

If the 4WD warning light comes on, the
4WD shift indicator turns off.
High-temperature transfer case oil makes
the 4WD warning light blink rapidly (about
twice per second). If the warning light blinks
rapidly during operation, stop the vehicle in a
safe place immediately. Then if the light
turns off after a while, you can continue
driving.
A large difference between the diameters of
front and rear wheels will make the 4WD
warning light blink slowly (about once per
two seconds). Change the 4WD shift switch
to AUTO and do not drive fast.
CAUTION
.If the 4WD warning light comes on or
blinks slowly during operation or
rapidly after stopping the vehicle for
a while, have your vehicle checked as
soon as possible. It is recommended
you visit an INFINITI retailer for this
service.
. Shifting between 4HI and 4LO is not
recommended when the 4WD warn-
ing light turns on.
. When the 4WD warning light comes
on, the 2WD mode may be engaged
even if the 4WD shift switch is in AUTO or 4H. Be especially careful
when driving. If corresponding parts
are malfunctioning, the 4WD mode
will not be engaged even if the 4WD
shift switch is shifted.
. Do not drive the vehicle in the 4HI or
4LO position on dry hard surface
roads. Driving on dry, hard surfaces
in 4HI or 4LO may cause unnecessary
noise, tire wear and increased fuel
consumption.
If the 4WD warning light turns on
when driving on dry hard surface
roads:
— in the AUTO or 4HI position, shift the 4WD shift switch to AUTO.
— in the 4LO position, stop the vehicle and shift the transmission
shift lever to the N (Neutral)
position and shift the 4WD shift
switch to AUTO.
. If the 4WD warning light is still on
after the above operation, have your
vehicle checked as soon as possible. It
is recommended you visit an INFINITI
retailer for this service. .
The transfer case may be damaged if
you continue driving with the warn-
ing light blinking.
