System operation
WARNING
Normally when controlling the distance to
a vehicle ahead, this system automatically
accelerates or decelerates your vehicle
according to the speed of the vehicle
ahead. Depress the accelerator to prop-
erly accelerate your vehicle when accel-
eration is required for a lane change. De-
press the brake pedal when deceleration
is required to maintain a safe distance to
the vehicle ahead due to its sudden brak-
ing or if a vehicle cuts in. Always stay alert
when using the ICC system.
The driver sets the desired vehicle speed based
on the road conditions. The ICC system main-
tains the set vehicle speed, similar to standard
cruise control, as long as no vehicle is detected in
the lane ahead.
The ICC system displays the set speed. The
CRUISE indicator light in the vehicle information
display comes on.
Vehicle detected ahead:
When a vehicle is detected in the lane ahead, the
ICC system decelerates the vehicle by control-
ling the throttle and applying the brakes to match
the speed of a slower vehicle ahead. The system then controls the vehicle speed based on the
speed of the vehicle ahead to maintain a driver
selected distance.
The stoplights of the vehicle come on and
the brake pedal depresses when braking is
performed by the ICC system.
CAUTION
Never place your foot under the brake
pedal, when the brake is operated by the
Intelligent Cruise Control system. You
may get your foot caught in the pedal.
When a vehicle ahead is detected, the vehicle
ahead detection indicator comes on. The ICC
system will also display the set speed and se-
lected distance.
Vehicle ahead not detected:
When a vehicle is no longer detected ahead, the
ICC system gradually accelerates your vehicle to
resume the previously set vehicle speed. The ICC
system then maintains the set speed.
When a vehicle is no longer detected the vehicle
ahead detection indicator turns off.
If a vehicle ahead appears during acceleration to
the set vehicle speed or any time the ICC system
is in operation, the system controls the distance
to the vehicle.

When passing another vehicle,the set speed
indicator will flash when the vehicle speed ex-
ceeds the set speed. The vehicle detect indicator
will turn off when the area ahead of the vehicle is
open. When the pedal is released, the vehicle will
return to the previously set speed. The CRUISE
indicator light will appear on the vehicle informa-
tion display.
Although your vehicle may be at the set vehicle
speed based on ICC system control, depress the
accelerator pedal when it is necessary to accel-
erate your vehicle rapidly.
How to change the set vehicle speed
To cancel the preset speed, use any of these
methods:
● Push the CANCEL switch. The set vehicle
speed indicator will go out.
● Tap the brake pedal. The set vehicle speed
indicator will go out.
● Turn the ON/OFF switch off. Both the
ON/OFF switch indicator and set vehicle
speed indicator will go out.
To reset at a faster cruising speed, use one
of the following methods:
● Depress the accelerator pedal. When the
vehicle attains the desired speed, push and
release the COAST/SET switch.
● Push and hold the ACCEL/RES switch. The
set vehicle speed will increase by approxi-
mately 5 MPH (5 km/h for Canada) .
● Push, then quickly release the ACCEL/RES
switch. Each time you do this, the set speed
will increase by approximately 1 MPH (1
km/h for Canada) . To reset at a slower cruising speed,
use one
of the following methods:
● Lightly tap the brake pedal. When the ve-
hicle attains the desired speed, push the
COAST/SET switch and release it.
● Push and hold the COAST/SET switch. The
set vehicle speed will decrease by approxi-
mately 5 MPH (5 km/h for Canada) .
● Push, then quickly release the COAST/SET
switch. Each time you do this, the set speed
will decrease by approximately 1 MPH (1
km/h for Canada) .
To resume the preset speed, push and re-
lease the ACCEL/RES switch. The vehicle will
resume the last set cruising speed when the
vehicle speed is over 25 MPH (40 km/h) .

How to change the set distance to the
vehicle ahead
The distance to the vehicle ahead can be se-
lected at any time depending on the traffic con-
ditions.
Each time the DISTANCE switch is pressed, the
set distance will change to long, medium, short
and back to long again in that sequence.●
The distance to the vehicle ahead will
change according to the vehicle speed. The
higher the vehicle speed, the longer the dis-
tance.
● If the engine is stopped, the set distance
becomes “long”. (Each time the engine is
started, the initial setting becomes “long”.)
● The CRUISE indicator light will appear in the
vehicle information display.
Approach warning
If your vehicle comes closer to the vehicle ahead
due to rapid deceleration of that vehicle or if
another vehicle cuts in, the system warns the
driver with the chime and ICC system display.
Decelerate by depressing the brake pedal to
maintain a safe vehicle distance if:
● The chime sounds.
● The vehicle ahead detection and set dis-
tance indicator blink.
The warning chime may not sound in some cases
when there is a short distance between vehicles.
Some examples are: ● When the vehicles are traveling at the same
speed and the distance between vehicles is
not changing.
● When the vehicle ahead is traveling faster
and the distance between vehicles is in-
creasing.
● When the accelerator pedal is depressed,
overriding the system.
● When a vehicle cuts in near your vehicle.
The warning chime will not sound when your
vehicle approaches vehicles that are parked or
moving slowly.

WARNING
●Never get under the vehicle while it is
supported only by the jack. If it is nec-
essary to work under the vehicle, sup-
port it with safety stands.
● Use only the jack provided with your
vehicle to lift the vehicle. Do not use the
jack provided with your vehicle on other
vehicles. The jack is designed for lifting
only your vehicle during a tire change.
● Use the correct jack-up points. Never
use any other part of the vehicle for jack
support.
● Never jack up the vehicle more than
necessary.
● Never use blocks on or under the jack. ●
Do not start or run the engine while
vehicle is on the jack. It may cause the
vehicle to move. This is especially true
for vehicles with limited slip
differentials.
● Do not allow passengers to stay in the
vehicle while it is on the jack.
● Never run the engine with a wheel(s) off
the ground. It may cause the vehicle to
move.
Always refer to the illustration for the correct
placement and jack-up points for your specific
vehicle model and jack type.
Carefully read the caution label attached to
the jack body and the following instruc-
tions. 1. Loosen each wheel nut one or two turns by turning counterclockwise with the wheel nut
wrench. Do not remove the wheel nuts
until the tire is off the ground. NOTE:
Before jacking up the vehicle, make sure
the ignition switch is placed in the OFF
position. If the vehicle is lifted up with the

FUEL RECOMMENDATION
INFINITI recommends the use of premium un-
leaded gasoline with an octane rating of at least
91 AKI (Anti-Knock Index) number (Research
octane number 96) . If unleaded premium gaso-
line is not available, you may use unleaded regular
gasoline with an octane rating of at least 87 AKI
number (Research octane number 91) , but you
may notice a decrease in performance.
CAUTION
●Using a fuel other than that specified
could adversely affect the emission
control system, and may also affect the
warranty coverage.
● Under no circumstances should a
leaded gasoline be used, because this
will damage the three-way catalyst.
● Do not use E-85 fuel in your vehicle.
Your vehicle is not designed to run on
E-85 fuel. Using E-85 fuel can damage
the fuel system components and is not
covered by the INFINITI vehicle limited
warranty.
Gasoline specifications
INFINITI recommends using gasoline that meets
the World-Wide Fuel Charter (WWFC) specifi-
cations where it is available. Many of the automo-
bile manufacturers developed this specification
to improve emission control system and vehicle
performance. Ask your service station manager if
the gasoline meets the WWFC specifications.
Reformulated gasoline
Some fuel suppliers are now producing reformu-
lated gasolines. These gasolines are specially
designed to reduce vehicle emissions. INFINITI
supports efforts towards cleaner air and sug-
gests that you use reformulated gasoline when
available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing oxy-
genates such as ethanol, MTBE and methanol with
or without advertising their presence. INFINITI
does not recommend the use of fuels of which the
oxygenate content and the fuel compatibility for
your INFINITI cannot be readily determined. If in
doubt, ask your service station manager.
If you use oxygenate-blend gasoline, please take
the following precautions as the usage of such
fuels may cause vehicle performance problems
and/or fuel system damage. ●
The fuel should be unleaded and have
an octane rating no lower than that
recommended for unleaded gasoline.
●
If an oxygenate-blend other than metha-
nol blend is used, it should contain no
more than 10% oxygenate. (MTBE may,
however, be added up to 15%.)
●If a methanol blend is used, it should
contain no more than 5% methanol (me-
thyl alcohol, wood alcohol) . It should
also contain a suitable amount of ap-
propriate cosolvents and corrosion in-
hibitors. If not properly formulated with
appropriate cosolvents and corrosion
inhibitors, such methanol blends may
cause fuel system damage and/or ve-
hicle 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 driveability problems such as engine stall-
ing and difficult 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 refu-
eling. Gasoline containing oxygenates can
cause paint damage.

Tow mode includes the following features:● Grade logic — Adjusts transmission shifts
when pulling a trailer or hauling a load up a
grade.
● Downhill Speed Control (DSC) — automati-
cally downshifts when driving down a grade
with a trailer or heavy load to help control
vehicle speed.
Driving the vehicle in the 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 driving
characteristics may feel unusual.
When towing a trailer, final drive gear oil
should be replaced and transmission
oil/fluid should be changed more fre-
quently. For additional information, see the
“Maintenance and do-it-yourself” section
earlier in this manual.
FLAT TOWING
Towing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is sometimes used when towing a vehicle
behind a recreational vehicle, such as a motor
home.
CAUTION
● Failure to follow these guidelines can
result in severe transmission damage.
● Whenever flat towing your vehicle, al-
ways tow forward, never backward.
● DO NOT tow any automatic transmis-
sion vehicle with all four wheels on the
ground (flat towing) . Doing so WILL
DAMAGE internal transmission parts
due to lack of transmission lubrication.
● For emergency towing procedures refer
to “Towing recommended by INFINITI”
in the “In case of emergency” section of
this manual.
Automatic Transmission
To tow a vehicle equipped with an automatic
transmission, an appropriate vehicle dolly MUST
be placed under the towed vehicle’s drive
wheels. Always follow the dolly manufacturer’s
recommendations when using their product.
WARNING
Do not use this vehicle for snowplowing.
Installing a snowplow may affect vehicle
handling. This may cause the driver to lose
control of the vehicle and could result in
serious vehicle damage or personal injury.
