2010 INFINITI QX ECO mode

●The system may not detect the vehicle
in front of you in certain road or weather
conditions. To avoid accidents, never
use the Intelligent Cruise Control sys-
tem under the following conditions:
– On roads where the traffic is heavy or there are sharp curves.
– On slippery road surfaces such as on ice or snow, etc.
– During bad weather (rain, fog, snow, etc.) (When the windshield wiper is
operated at the low speed (LO) or
high speed (HI) position, the Intelli-
gent Cruise Control system is auto-
matically canceled.)
– When strong light (for example, at sunrise or sunset) is directly shining
on the front of the vehicle.
– When rain, snow or dirt adhere to the system sensor.
– On steep downhill roads (the vehicle may go beyond the set vehicle speed
and frequent barking may result in
overheating the brakes) .
– On repeated uphill and downhill roads. – When traffic conditions make it diffi-
cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration.
● Do not use the Intelligent Cruise Con-
trol system if you are towing a trailer.
The system may not detect a vehicle
ahead.
● In some road or traffic conditions, a
vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. You may
need to control the distance from other
vehicles using the accelerator pedal. Al-
ways stay alert and avoid using the ICC
system when it is not recommended in
this section.
Vehicle-to-vehicle distance mode
operation
Always pay attention to the operation of the ve-
hicle and be ready to manually control the proper
following distance. The Intelligent Cruise Control
(ICC) system may not be able to maintain the
selected distance between vehicles (following
distance) or selected vehicle speed under some
circumstances.
The vehicle-to-vehicle distance control mode
uses a sensor
1located on the front of the
vehicle to detect vehicles ahead. The sensor
generally detects the signals returned from the
reflectors on a vehicle ahead. Therefore, if the

sensor cannot detect the reflector of the vehicle
ahead, the ICC system may not maintain the
selected distance.
The following are some conditions in which the
sensor cannot detect the signals:● When the reflector is positioned high on the
vehicle (trailer, etc.) .
● When the reflector on the vehicle ahead is
missing, damaged or covered.
● When the reflector is covered with dirt, snow
and road spray.
● When the snow or road spray from other
vehicles reduces the sensor’s visibility.
● When dense exhaust or other smoke (black
smoke) from vehicles reduces the sensor’s
visibility.
● When excessively heavy baggage is loaded
in the rear seat or the cargo area of your
vehicle.
● When your vehicle is towing a trailer, etc.
The ICC system is designed to automatically
check the sensor’s operation. When the sensor is
covered with dirt or obstructions, the system will
automatically be canceled while allowing con-
ventional cruise control to remain operational. If
the sensor is covered with ice, a transparent or translucent vinyl bag, etc., the ICC system may
not detect them. In these instances, the vehicle-
to-vehicle distance control mode may not cancel
and may not be able to maintain the selected
following distance from the vehicle ahead. Be
sure to clean the sensor regularly.
The vehicle-to-vehicle distance control mode is
designed to maintain a selected distance and
reduce the speed to match the speed of a slower
vehicle ahead; the system decelerates the ve-
hicle as necessary. However, the ICC system can
only apply up to 25% of the vehicle’s total braking
power. This system should only be used when
traffic conditions allow vehicle speeds to remain
fairly constant or vehicle speeds change gradu-
ally. If a vehicle moves into the traveling lane
ahead or if a vehicle traveling ahead rapidly de-
celerates, the distance between vehicles may
become closer because the ICC system cannot
decelerate the vehicle quickly enough. If this oc-
curs, the ICC system will sound a warning chime
and blink the system display to notify the driver to
take necessary action.
The system will cancel and a warning chime will
sound if the speed falls below approximately 20
MPH (32km/h) . The system will also disengage
below the 20 MPH (32km/h) cut-off speed or
over the maximum set speed.
Refer to “Approach warning” later in this section.The following items are controlled when the se-
lector lever is in any D (Drive) position.
● When there are no vehicles traveling ahead,
the vehicle-to-vehicle distance control
mode maintains the speed set by the driver.
The set speed range is between approxi-
mately 25 and 89 MPH (40 and 144 km/h) .
● When there is a vehicle traveling ahead, the
vehicle-to-vehicle distance control mode
adjusts the speed to maintain the distance
selected by the driver from the vehicle
ahead. The adjusting speed range is be-
tween approximately 20 MPH (32 km/h) and
the set speed.
● When the vehicle traveling ahead has moved
out from its lane of travel, the vehicle-to-
vehicle distance control mode accelerates
and maintains speed up to the set speed.
The ICC system does not control vehicle speed
or warn you when you approach stationary and
slow moving vehicles. You must pay attention to
vehicle operation to maintain proper distance
from vehicles ahead when approaching toll gates
or traffic congestion.

BRAKE ASSIST
When the force applied to the brake pedal ex-
ceeds a certain level, the Brake Assist is acti-
vated, generating greater braking force than a
conventional brake booster even with light pedal
force.
WARNING
The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the driv-
er’s responsibility to stay alert, drive
safely and be in control of the vehicle at
all times.
PREVIEW FUNCTION
When the Preview Function identifies the need to
apply emergency braking by sensing a vehicle
ahead in the same lane and the distance and
relative speed from it, it applies the brake pre-
pressure before the driver depresses the brake
pedal and helps improve brake response by re-
ducing pedal free play.●
This system will not operate when the ve-
hicle is moving at approximately 20 MPH (32
km/h) or less.
● The pre-pressure function ceases when the
following conditions are met:
a. When the driver depresses the accelerator pedal or the brake pedal.
b. If the driver does not operate the accelerator or brake pedal within approximately 1 second.
●The sensor will not detect:
a. Pedestrians or objects in the roadway
b. Oncoming vehicles in the same lane
c. Motorcycles or scooters traveling offset in the travel lane as illustrated

If the indicator stays on, it may indicate that
the Preview Function is malfunctioning
(the brake is operative) . Although the Ve-
hicle is still driveable under normal condi-
tions, have the vehicle checked at an
INFINITI dealer.
Sensor maintenance
The sensor for the Preview Function, is common
with Intelligent Cruise Control and is located
below the front bumper.
To keep the Preview Function operating properly,
be sure to observe the following:● Always keep the sensor clean. Wipe with a
soft cloth carefully so as not to damage
them.
● Do not impact the areas around the sensor.
Do not touch or disassemble the screw lo-
cated on the sensor. Doing so could cause
failure or malfunction. If the sensor installa-
tion part is deformed due to an accident,
contact an INFINITI dealer.
● Do not attach a sticker (including transpar-
ent material) or install an accessory near the
sensor. This could cause failure or malfunc-
tion.
CAUTION
During the first 1,200 miles (2,000 km) ,
follow these recommendations to obtain
maximum engine performance and en-
sure the future reliability and economy of
your new vehicle. Failure to follow these
recommendations may result in short-
ened engine life and reduced engine
performance.
● Avoid driving for long periods at constant
speed, either fast or slow, and do not run the
engine over 4,000 rpm.
● Do not accelerate at full throttle in any gear.
● Avoid quick starts.
● Avoid hard braking as much as possible.
● Do not tow a trailer for the first 500 miles
(800 km) . Your engine, axle or other parts
could be damaged. ●
Accelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
● Drive at moderate speeds on the highway.
Driving at high speed lowers fuel economy.
● Avoid unnecessary stopping and braking.
Maintain a safe distance behind other ve-
hicles.
● Use a proper gear range which suits road
conditions. On level roads, shift into high
gear as soon as possible.
● Avoid unnecessary engine idling.
● Keep your engine tuned up.
● Follow the recommended periodic mainte-
nance schedule.
● Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
● Keep the front wheels in correct alignment.
Improper alignment increases tire wear and
lowers fuel economy.
● Air conditioner operation lowers fuel
economy. Use the air conditioner only when
necessary.

The transfer case 4WD shift switch is used to
select either 2WD or 4WD depending on the
driving conditions. There are four types of drive
modes available, AUTO, 2WD, 4H and 4LO.
The 4WD shift switch electronically controls the
transfer case operation. Rotate the switch to
move between each mode, 2WD, AUTO, 4H and
4LO.
You must push the switch in to select 4LO,
and the vehicle MUST be stationary and the
shift selector in the N position when chang-
ing into or out of 4LO.
WARNING
When parking, apply the parking brake
before stopping the engine and make sure
that the 4WD shift indicator light is on and
the ATP warning light goes off. Otherwise,
the vehicle could unexpectedly move even
if the automatic transmission is in the P
position.
CAUTION
●Never shift the 4WD shift switch be-
tween 4LO and 4H while driving.
● The 4H position provides greater trac-
tion. Avoid excessive speed, as it will
cause increased fuel consumption and
higher oil temperatures, and could
damage drivetrain components.
Speeds over 62 MPH (100 km/h) in 4H is
not recommended.
● The 4LO position provides maximum
power and traction. Avoid raising ve-
hicle speed excessively, as the maxi-
mum speed is approximately 31 MPH
(50 km/h) .
● When driving straight, shift the 4WD
shift switch to the 2WD, AUTO or 4H
position. Do not move the 4WD shift
switch when making a turn or reversing.
● Do not shift the 4WD shift switch (be-
tween 2WD, AUTO and 4H) while driving
on steep downhill grades. Use the en-
gine brake and low automatic transmis-
sion gears (D1 or D2) for engine
braking. ●
Do not operate the 4WD shift switch
(between 2WD, AUTO and 4H) with the
rear wheels spinning.
● Do not drive on dry hard surface roads
in the 4H or 4LO position. Driving on dry
hard surfaces in 4H or 4LO may cause
unnecessary noise and tire wear.
INFINITI recommends driving in the
2WD or AUTO position under these
conditions.
● The 4WD transfer case may not be
shifted between 4H and 4LO at low am-
bient temperatures and the transfer
4LO position indicator light may blink
even when the 4WD shift switch is
shifted. After driving for a while you can
change the 4WD transfer case between
4H and 4LO.
When driving on rough roads, ● Set the 4WD shift switch to AUTO, 4H or
4LO.
● Drive carefully according to the road surface
conditions.

●Before placing the 4WD shift switch in
the 4H position from 2WD or AUTO,
ensure the vehicle speed is less than 62
MPH (100 km/h) . Failure to do so can
damage the 4WD system.
● Never shift the 4WD shift switch be-
tween 4LO and 4H while driving.
● Engine idling speed is high while warm-
ing up the engine. Be especially careful
when starting or driving on slippery sur-
faces with the 4WD shift switch set in
AUTO.
4WD shift indicator light
The 4WD shift indicator light is located in the
vehicle information display.
The light should turn off within 1 second after
turning the ignition switch to the ON position.
While the engine is running, the 4WD shift indi-
cator light will illuminate the position selected by
the 4WD shift switch.
● The 4WD shift indicator light may blink
while shifting from one drive mode to
the other. When the shifting is com-
pleted, the 4WD shift indicator light
will come on. If the indicator light does
not come on immediately, make sure
the area around the vehicle is safe, and drive the vehicle straight, accelerate or
decelerate or move the vehicle in re-
verse, then shift the 4WD shift switch.
● If the 4WD warning light comes on, the
4WD indicator light goes out.
CAUTION
● When the 4WD shift switch is turned to
the AUTO position at low ambient tem-
peratures, the 4WD shift indicator light
may show 4H. If this happens, all four
wheels are driven as torque distribution
is in the 4H position. Be careful as the
vehicle may become difficult to turn.
When the vehicle is driven, the 4WD
shift indicator light should change to
AUTO.
● If the 4WD shift indicator light indica-
tion changes to 2WD when the 4WD
shift switch is shifted to the AUTO or 4H
position at low ambient temperatures,
the 2WD mode may be being engaged
due to malfunctioning drive system. If
the indicator does not return to normal
and the 4WD warning light comes on,
have the system checked by the nearest
INFINITI dealer.

4WD warning light
Warning lightComes on or blinks
when:
Comes on There is a malfunc-
tion in the 4–wheel drive 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 igni-
tion 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 ON, the warning light
will either remain illuminated or blink.
If the 4WD warning light comes on, the 4WD
shift indicator light goes out. High-temperature transfer case oil makes the
warning light blink rapidly (about twice per sec-
ond) . If the warning light blinks rapidly during
operation, stop the vehicle in a safe place imme-
diately. Then if the light goes off after a while, you
can continue driving.
A large difference between the diameters of front
and rear wheels will make the warning light blink
slowly (about once per two seconds) . Change
the 4WD shift switch into 2WD and do not drive
fast.
CAUTION
●
If the 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
dealer as soon as possible.
● Shifting between 4H and 4LO is not
recommended when the 4WD warning
light turns on.
● When the 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 corre-
sponding 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 4H or 4LO
position on dry hard surface roads. Driv-
ing on dry, hard surfaces in 4H or 4LO
may cause unnecessary noise, tire wear
and increased fuel consumption.
If the 4WD warning light turns on when
you are driving on dry hard surface
roads:
– in the AUTO or 4H position, shift the 4WD shift switch to 2WD.
– in the 4LO position, stop the vehicle, move the automatic transmission
shift selector to the N position with
the brake pedal depressed, and shift
the 4WD shift switch to 2WD.
● If the warning light is still on after the
above operation, have your vehicle
checked by an INFINITI dealer as soon
as possible.
● The transfer case may be damaged if
you continue driving with the warning
light blinking.
