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/Mainte-
nance (I/M) test” (P.10-33).)
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
appears in the vehicle information 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 thelight does not turn off
after a few driving trips, have the vehicle
inspected. It is recommended you visit an
INFINITI retailer for this service. 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 sys-
tem.
To reduce or avoid emission control
system damage:
1) Do not drive at speeds above 45 MPH (72 km/h).
2) Avoid hard acceleration or decelera- tion.
3) Avoid steep uphill grades.
4) 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. It is recom-
mended you visit an INFINITI retailer for
this service. You do not need to have
your vehicle towed to the retailer.
CAUTION
Continued vehicle operation without
having the emission control system
checked and repaired as necessary could
lead to poor driveability, reduced fuel
economy, and possible damage to the
emission control system.
Security indicator light
The light blinks when the ignition switch is in
the ACC, OFF and LOCK position. This
function indicates the security system
equipped on the vehicle is operational.
If the security system is malfunctioning, this
light will remain on while the ignition switch
is in the ON position. For additional informa-
tion, see “Security systems” (P.2-31).

Current fuel consumption ?Average fuel
consumption and speed ?Elapsed time and
trip odometer ?Distance to empty (dte) ?

Outside air temperature (ICY)?Setting ?
Warning check
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
switchfor 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
switchfor
longer than 1 second. (The average fuel
consumption is also reset at the same time.)

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 con-
tinue 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 — °F
or °C)
The outside air temperature is displayed in °F
or °C in the range of −22 to 131°F (−30 to
55°C).

TOW mode should be used when pulling a
heavy trailer or hauling a heavy load. Driving
the vehicle in TOW mode with no trailer/
load or light trailer/light load will not cause
any damage. However, fuel economy may be
reduced, and the transmission/engine driv-
ing characteristics may feel unusual.
Push the TOW mode switch to activate
TOW mode. The indicator light on the TOW
mode switch illuminates when TOW mode is

The vehicle should be driven with the Vehicle
Dynamic Control (VDC) system on for most
driving conditions.
If the vehicle is stuck in mud or snow, the
VDC system reduces the engine output to
reduce wheel spin. The engine speed will be
reduced even if the accelerator is depressed
to the floor. If maximum engine power is
needed to free a stuck vehicle, turn the VDC
system off.
To turn off the VDC system, push the VDC
OFF switch. The
indicator will illumi-
nate.
Push the VDC OFF switch again or restart
the engine to turn on the system. (See
