Charge warning light
If the light comes on while the engine is run-
ning, it may indicate the charging system is not
functioning properly. Turn the engine off and
check the alternator belt. If the belt is loose,
broken, missing or if the light remains on, see
an INFINITI retailer immediately.
CAUTION
Do not continue driving if the alternator belt is
loose, broken or missing.
Distance Control Assist (DCA)
system warning light
(orange; if so equipped)
This light comes on if there is a malfunction in
the Distance Control Assist (DCA) system.
If the warning light illuminates, park the vehicle
in a safe place. Turn the engine off, restart the
engine, resume driving and turn on the DCA
system again.
If it is not possible to turn on the system or the
warning light stays on, it may indicate that the
system is malfunctioning. Although the vehicle
is still driveable under normal conditions, have
the vehicle checked at an INFINITI retailer.See “DISTANCE CONTROL ASSIST (DCA) SYS-
TEM” in the “5. Starting and driving” section.
Engine oil pressure warning
light
This light warns of low engine oil pressure. If
the light flickers or comes on during normal
driving, pull off the road in a safe area, stop the
engine
immediately and call an INFINITI retailer
or other authorized repair shop.
The engine oil pressure warning light is not de-
signed to indicate a low oil level. Use the dip-
stick to check the oil level. (See “ENGINE OIL” in
the “8. Maintenance and do-it-yourself” sec-
tion.)
CAUTION
Running the engine with the engine oil pres-
sure warning light on could cause serious dam-
age to the engine almost immediately. Such
damage is not covered by warranty. Turn off the
engine as soon as it is safe to do so.
Four-Wheel Drive (4WD)
warning light (4WD models)
Thewarning light comes on when the
ignition switch is pushed to ON. It turns off
soon after the engine is started.
If the 4WD system malfunctions, or the diam-
eter of the front and the rear wheels are differ-
ent, the warning light will either remain illumi-
nated or blink. (See “INFINITI ALL-MODE 4WD”
in the “5. Starting and driving” section.)
CAUTION
● If the warning light comes on while driving
there may be a malfunction in the 4WD sys-
tem. Reduce the vehicle speed and have your
vehicle checked by an INFINITI retailer as
soon as possible.
● If the 4WD warning light turns on when driv-
ing on dry or hard surfaced roads:
– in the 4H(I) position, shift the 4WD shift switch to AUTO
– in the 4L(O) position, stop the vehicle and shift the transmission selector lever to
the “N” (Neutral) position and shift the
4WD shift switch to AUTO

Lane Departure Prevention
(LDP) ON indicator light
(green; if so equipped)
The light comes on in green when the Lane
Departure Prevention (LDP) system is turned on.
The light turns off when the system is turned off.
NOTE:
This light is common with the lane departure
warning light (orange). (See “Lane departure
warning light” earlier in this section.)
For more details, see “LANE DEPARTURE WARN-
ING (LDW)/PREVENTION (LDP) SYSTEM” in the
“5. Starting and driving” section.
Low beam indicator light
The light illuminates when the front park, side
marker, tail and license plate lights are on.
Malfunction Indicator Light
(MIL)
If the malfunction indicator light comes on
steady or blinks while the engine is running, it
may indicate a potential emission control mal-
function.
The malfunction indicator light may also come
on steady if the fuel-filler cap is loose ormissing, 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 US gallons (14 liters) of fuel in the fuel tank.
After a few driving trips, the
light should
turn off if no other potential emission control
system malfunction exists.
If this indicator light remains on 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. (See “READINESS
FOR INSPECTION/MAINTENANCE (I/M) TEST” in
the “9. Technical and consumer information”
section.)
Operation :
The malfunction indicator light will come on in
one of two ways:
● Malfunction indicator light on steady — An
emission control system malfunction has
been detected. Check the fuel-filler cap if the
LOOSE FUEL CAP warning (if so equipped)
appears in the dot matrix liquid crystal dis-
play. If 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 the
light does not turn off after a few driving trips, have the vehicle inspected by an
INFINITI retailer. You do not need to have
your vehicle towed to the retailer.
● Malfunction indicator light blinking — An
engine misfire has been detected which may
damage the emission control system.
To reduce or avoid emission control system
damage:
a) Do not drive at speeds above 45 MPH (72 km/h).
b) Avoid hard acceleration or deceleration.
c) Avoid steep uphill grades.
d) If possible, reduce the amount of cargo being hauled or towed.
The malfunction indicator light may stop
blinking and remain on.
Have the vehicle inspected by an INFINITI
retailer. You do not need to have your vehicle
towed to the retailer.

4. Distance to empty (dte — MILES or
km)
The distance to empty (dte) mode provides you
with an estimation of the distance that can be
driven before refueling. The dte is constantly
being calculated, based on the amount of fuel
in the fuel tank and the actual fuel consump-
tion.
The display is updated every 30 seconds.
The dte mode includes a low range warning
feature. If the fuel level is low, the warning is
displayed on the screen.
When the fuel level drops even lower, the dte
display will change to “——”.
●If the amount of fuel added is small, the
display just before the ignition switch is
pushed to the OFF position may continue to
be displayed.
● When driving uphill or rounding curves, the
fuel in the tank shifts, which may momen-
tarily change the display.

°C in the range of 22 to 131°F (30 to 55°C). The outside air temperature mode includes a
low temperature warning feature. If the outside
air temperature is below 37°F (3°C), the warning
is displayed on the screen.
The outside temperature sensor is located in
front of the radiator. The sensor may be affected
by road or engine heat, wind directions and
other driving conditions. The display may differ
from the actual outside temperature or the
temperature displayed on various signs or bill-
boards.

The rain sensor sensitivity level can be adjusted
by turning the knob toward the front
2(High)
or toward the rear
3(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 in-
jury or a wiper damage.
● The rain-sensing auto wipers are intended for
use during rain. If the switch is left in the
AUTO position, the wipers may operate unex-
pectedly 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 oper-
ate 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.
● Using genuine wiper blades is recommended
for proper operation of the rain-sensing auto
wiper system. (See “WINDSHIELD WIPER
BLADES” in the “8. Maintenance and do-it-
yourself” section for wiper blade replace-
ment.)
WARNING
In freezing temperatures the washer solution
may freeze on the rear window glass and ob-
scure your vision. Warm the rear window with
the defroster before you wash the rear window.
CAUTION
● Do not operate the washer continuously for
more than 30 seconds.
● Do not operate the washer if the reservoir
tank is empty.
● Do not fill the window washer reservoir tank
with washer fluid concentrates at full
strength. Some methyl alcohol based
washer fluid concentrates may permanently
stain the grille if spilled while filling the win-
dow washer reservoir tank.
● Pre-mix washer fluid concentrates with wa-
ter to the manufacturer’s recommended lev-
els before pouring the fluid into the window
washer reservoir tank. Do not use the win-
dow washer reservoir tank to mix the washer
fluid concentrate and water.
