1. Current and average fuel con-
sumption
The current and average fuel consumption
mode shows the current and average fuel
consumption.
2. Average fuel consumption (MPG
or l (liter)/100 km) and speed (MPH
or km/h)
Fuel consumption:
The average fuel consumption mode shows
the average fuel consumption since the
last reset. Resetting is done by pushing the
switch*Bfor longer than 1 second.
(The average speed is also reset at the
same time.)
The display is updated every 30 seconds.
At about the first 1/3 mile (500 m) after a
reset, the display shows “——”.
Speed:
The average speed mode shows the
average vehicle speed since the last reset. Resetting is done by pushing the
switch*Bfor longer than 1 second. (The
average fuel consumption is also reset at
the same time.)
The display is updated every 30 seconds.
The first 30 seconds after a reset, the
display shows “——”.
3. Elapsed time and trip odometer
(MILES or km)
Elapsed time:
The elapsed time mode shows the time
since the last reset. The displayed time can
be reset by pushing the
switch*Bfor
longer than 1 second. (The trip odometer is
also reset at the same time.)
Trip odometer:
The trip odometer mode shows the total
distance the vehicle has been driven since
the last reset. Resetting is done by pushing
the
switch*Bfor longer than 1
second. (The elapsed time is also reset at
the same time.)
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 consumption.
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
momentarily change the display.
5. Outside air temperature (ICY —8F
or 8C)
The outside air temperature is displayed in
8For 8C in the range of −22 to 1318F(−30
to 558C).
The outside air temperature mode includes
a low temperature warning feature. If the
outside air temperature is below 378 F
(38C), the warning is displayed on the
screen.

Fuel Economy information
The approximate distance to empty, aver-
age fuel economy and current fuel econo-
my will be displayed for reference.
To reset the average fuel economy (Avg
Fuel Econ), select the“Reset Fuel Eco”key.
If the “Fuel Eco History” key is selected,
the average fuel consumption history will
be displayed in graph form along with the
average for the previous Reset-to-Reset
period.
The unit can be converted between “US”
and “Metric”. (See “How to use SETTING
button” later in this section.)
The fuel economy information may differ
from the information displayed on the
vehicle information display. This is due to
the timing difference in updating the
information and does not indicate a mal-
function.
SAA3146
TIRE PRESSURE information
WARNING
. When a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI retailer as soon as
possible for tire replacement and/or
system resetting. .
Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
The tire pressure will be displayed for
reference.
The pressure indication “** kPa”or“**
psi ”on the screen means that the pressure
is being measured. After a few driving
trips, the pressure for each tire will be
displayed.
To change the measurement units, select
the “Select Units” key with the INFINITI
controller and push the ENTER button.
In case of low tire pressure, LOW PRES-
SURE information will be displayed on the
screen. Check the pressure of all tires.
Tire pressure rises and falls depending on
the heat caused by the vehicle’s traveling
condition and the temperature.
After tire rotation is performed, tire pres-
sure will not be displayed in the actual tire
position. Drive the vehicle at over 25 MPH
(40 km/h) for approximately 10 minutes to
reset the display.
For more details about the Tire Pressure
Monitoring System (TPMS), see “Tire Pres-
sure Monitoring System (TPMS)” in the“5.

5-100Starting and driving
.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
recommendation” in the“9. Technical
and consumer information” section.)
WARNING
.Do not attempt to raise two wheels off
the ground and shift the transmission to
any drive or reverse position 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 dynamometer or
similar equipment even if the other two
wheels are raised off the ground. Make
sure you inform test facility personnel
that your vehicle is equipped with 4WD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected 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 in 4HI or 4LO may cause unnecessary noise, tire
wear and increased fuel consumption.
If the Four-Wheel Drive (4WD) warning
light turns on when driving on dry hard
surface roads:
—in the 4HI position, shift the 4WD
shift switch to AUTO.
—in the 4LO position, stop the vehicleand shift the transmission lever to
the N (Neutral) position with the
brake pedal depressed and shift the
4WD shift switch to AUTO.
If the 4WD warning light is still on
after the above operation, have your
vehicle checked by an INFINITI retai-
ler as soon as possible.
. The transfer case may be damaged if you
continue driving with the 4WD warning
light blinking.
See “On-pavement and off-road driving
precautions” earlier in this section for
other precautions for offroad driving.
INCREASING FUEL ECONOMY INFINITI ALL-MODE 4WD®(if so equipped)

The 4WD shift switch is used to select the
4WD mode depending on the driving
conditions. There are 3 types of drive
modes available, AUTO, 4HI and 4LO.
The 4WD shift switch electronically con-
trols 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
stationary 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 unexpect-
edly move even if the automatic trans-
mission 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 transmission 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 alternately, the vehicle may
move unexpectedly.
CAUTION
.
Never shift the 4WD shift switch be-
tween 4L and 4H while driving.
. The 4HI position provides greater trac-
tion. Avoid excessive speed, as it will
cause increased fuel consumption and
higher oil temperatures, and could da-
mage 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 reversing.
. Do not shift the 4WD shift switch
(between AUTO and 4H) while driving
on steep downhill grades. Use the engine brake and low automatic trans-
mission gears for engine braking.
. 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 between 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
Starting and driving5-103

5-106Starting and driving
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 by an INFINITI
retailer as soon as possible.
. Shifting between 4HI and 4LO is not
recommended when the 4WD warning 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 by an INFINITI retailer as soon
as possible.
. The transfer case may be damaged if you
continue driving with the warning light blinking.

fuel is not covered by the INFINITI new
vehicle limited warranty.
. If a methanol blend is used, it should
contain no more than 5% methanol
(methyl alcohol, wood alcohol). It
should also contain a suitable amount
of appropriate cosolvents and corro-
sion inhibitors. If not properly formu-
lated with appropriate cosolvents and
corrosion inhibitors, such methanol
blends may cause fuel system damage
and/or vehicle performance problems.
At this time, sufficient data is not
available to ensure that all methanol
blends are suitable for use in INFINITI
vehicles.
If any undesirable driveability problems
such as engine stalling or hard hot starting
are experienced after using oxygenate-
blend fuels, immediately change to a
non-oxygenate fuel or a fuel with a low
blend of MTBE.
Take care not to spill gasoline during
refueling. Gasoline containing oxygenates
can cause paint damage.
E-15 fuel
E-15 fuel is a mixture of approximately
15% fuel ethanol and 85% unleaded gasoline. E-15 can only be used in vehicles
designed to run on E-15 fuel. Do not use E-
15 in your vehicle. U.S. government
regulations require fuel ethanol dispensing
pumps to be identified with small, square,
orange and black label with the common
abbreviation or the appropriate percentage
for that region.
E-85 fuel
E-85 fuel is a mixture of approximately
85% fuel ethanol and 15% unleaded
gasoline. E-85 can only be used in a
Flexible Fuel Vehicle (FFV). Do not use E-
85 fuel in your vehicle. U.S. government
regulations require fuel ethanol dispensing
pumps to be identified by a small, square,
orange and black label with the common
abbreviation or the appropriate percentage
for that region.
Aftermarket fuel additives
INFINITI does not recommend the use of
any aftermarket fuel additives (Example:
fuel injector cleaner, octane booster, intake
valve deposit removers, etc.) which are
sold commercially. Many of these additives
intended for gum, varnish or deposit
removal may contain active solvent or
similar ingredients that can be harmful tothe fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended above can
cause persistent, heavy spark knock.
(Spark knock is a metallic rapping noise.)
If severe, this can lead to engine damage.
If you detect a persistent heavy spark
knock even when using gasoline of the
stated octane rating, or if you hear steady
spark knock while holding a steady speed
on level roads, have an INFINITI retailer
correct the condition. Failure to correct the
condition is misuse of the vehicle, for
which INFINITI is not responsible.
Incorrect ignition timing will result in
knocking, after-run or overheating. This in
turn may cause excessive fuel consumption
or damage to the engine. If any of the
above symptoms are encountered, have
your vehicle checked at an INFINITI retailer
or other competent service facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
