2011 INFINITI QX stop start

The stoplights of the vehicle come on when brak-
ing is performed by the DCA system.
When the brake operates, a noise may be heard
or felt. This is not a malfunction.
WARNING
●When the vehicle ahead detection indicator
is not illuminated, system will not control or
warn the driver.
● Depending on the position of the accelerator
pedal, the system may not be able to assist
the driver to release the accelerator pedal
appropriately.
● If the vehicle ahead comes to a standstill,
the vehicle decelerates to a standstill within
the limitations of the system. The system
will release brake control with a warning
chime once it judges the vehicle is at a
standstill. To prevent the vehicle from mov-
ing, the driver must depress the brake pedal.
(The system will resume control automati-
cally once the system reaches 3 MPH (5
km/h). Overriding the system :
The following driver’s operation overrides the
system operation.
●
When the driver depresses the accelerator
pedal even further while the system is mov-
ing the accelerator pedal upward, the DCA
system control of the accelerator pedal is
canceled.
● When the driver’s foot is on the accelerator
pedal, the brake control by the system is not
operated.
● When the driver’s foot is on the brake pedal,
neither the brake control nor the alert by the
system operates.
● When the Intelligent Cruise Control (ICC)
system is set, the DCA system will be can-
celled.
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 DCA system
display. Decelerate by depressing the brake
pedal to maintain a safe vehicle distance if:
● The chime sounds.
● The vehicle ahead detection indicator blinks.
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 a vehicle cuts in near your vehicle
The warning chime will not sound when your
vehicle approaches vehicles that are parked or
moving slowly.
5-72Starting and driving

●The system may not function when the dis-
tance to the vehicle ahead is extremely
close.
● The system is designed to automatically
check the sensor’s functionality. If the sen-
sor is covered with ice, a transparent or
translucent plastic bag, etc., the system may
not detect them. In these instances the sys-
tem may not be able to warn the driver prop-
erly. Be sure to check and clean the sensor
regularly.
● Excessive noise will interfere with the warn-
ing chime sound, and the chime may not be
heard.
● A sudden appearance of a vehicle in front
(i.e., it abruptly cuts in) may not be detected
and the system may not warn the driver soon
enough.
● The system will be cancelled automatically
with a beep sound and the IBA OFF indicator
light will illuminate under the following
conditions:
– When the sensor window is dirty
– When the system malfunctions If the IBA OFF indicator light
Ailluminates with
a beep sound, pull off the road to a safe
location, stop the vehicle and turn the engine
off. Check to see if the sensor window is dirty.
If the sensor window is dirty, clean it with a soft
cloth and restart the engine. If the sensor
window is not dirty, restart the engine. If the
IBA OFF indicator light continues to illuminate
even if the IBA system is turned on with the IBA
OFF switch
B, have the system checked by an
INFINITI retailer.

The IBA system will remain in the last ON or OFF
state it was left in until it is manually changed
by pressing the IBA OFF switch.
Illumination of the IBA OFF indicator light with-
out a beep sound is an indication that the IBA
system is temporarily unavailable. It will occur
under the following conditions:
– When driving into a strong light (for example,sunlight)
– When the 4WD shift switch is in the 4H or 4L position (for 4WD models)
The IBA OFF indicator light will turn off when the
system returns to its normal operating condi-
tions.
For the sensor maintenance, see “Sensor main-
tenance” earlier in this section.CAUTION
During the first 1,200 miles (2,000 km), follow
these recommendations to obtain maximum
engine performance and ensure the future reli-
ability and economy of your new vehicle.
Failure to follow these recommendations may
result in shortened engine life and reduced en-
gine performance.
● Avoid driving for long periods at constant
speed, either fast or slow. 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
(805 km). ●
Accelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
● Drive at moderate speeds on the highway.
● Avoid unnecessary stopping and braking.
Keep a safe distance behind other vehicles.
● Select a gear range suitable to road condi-
tions.
● Avoid unnecessary prolonged engine idling.
● Keep your engine tuned up.
● Follow the recommended periodic mainte-
nance schedule.
● Keep the tires inflated at the correct pres-
sure. Improper tire pressure will increase
wear and waste fuel.
● Make sure the front wheels are properly
aligned. Improper alignment will cause pre-
mature tire wear and lower fuel economy.
● Climate control operation lowers fuel
economy. Use the air conditioner only when
necessary.
● When cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag.

WARNING
●Do not attempt to raise two wheels off the
ground and shift the transmission to any
drive or reverse position with the engine run-
ning. Doing so may result in drivetrain dam-
age or unexpected vehicle movement which
could result in serious vehicle damage or
personal injury.
● Do not attempt to test a 4WD equipped ve-
hicle 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 equip-
ment may result in drivetrain damage or un-
expected vehicle movement which could re-
sult 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 in-
creased 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 vehicle and shift the transmission lever to the N (Neu-
tral) position with the brake pedal de-
pressed 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 4WD warning light
blinking.
See “ON-PAVEMENT AND OFF-ROAD DRIVING
PRECAUTIONS” earlier in this section for other
precautions for offroad driving.
INFINITI ALL-MODE 4WD SYSTEM
The all mode 4WD system provides 3 positions
(AUTO, 4HI and 4LO), so you can select the
desired drive mode according to the driving
conditions.
INFINITI ALL-MODE 4WD(if so equipped)
5-84Starting and driving

4WD shift procedure:
*1: The 4LO and 4HI indicator may flash alternately. Stop the vehicle and be sure to turn the 4WD shift switch after the transmission selector lever has
been shifted to the N (Neutral) position. If the indicator keeps flashing after the 4WD shift procedure, drive slowly without abrupt maneuvers for a while.
Then the indicator will illuminate or turn off.
· Avoid making a turn or abrupt starts while shifting to the 4LO position. Otherwise the gears may grind, damaging the drive system.
SSD1100
Starting and driving5-85

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 controls 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
selector lever in the N (Neutral) position when
changing into or out of 4L.
WARNING
●When parking, apply the parking brake be-
fore stopping the engine and make sure that
the 4WD shift indicator is on and the ATP
warning light turns off. Otherwise, the ve-
hicle could unexpectedly move even if the
automatic transmission is in the P (Park)
position.
● The 4LO and 4HI indicators must stop blink-
ing and the 4LO or 4HI indicator must remain
illuminated or turn off before shifting the
transmission into gear. If the selector 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 between 4L
and 4H while driving.
● The 4HI position provides greater traction.
Avoid excessive speed, as it will cause in-
creased fuel consumption and higher oil
temperatures, and could damage drivetrain
component. Speeds over 62 MPH (100 km/h)
in 4HI is not recommended.
● The 4LO position provides maximum trac-
tion. Avoid raising vehicle speed exces-
sively, as the maximum speed is approxi-
mately 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 down-
hill grades. Use the engine brake and low
automatic transmission gears for engine
braking.
● Do not operate the 4WD shift switch (be-
tween 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 sur-
faces 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 tem-
peratures 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 increase
the movement.
● If the vehicle is stuck deep in mud, tire
chains may be effective.
Starting and driving5-87

CAUTION
●Do not spin the tires excessively. Tires will
sink deep into the mud, making it difficult to
free the vehicle.
● Avoid shifting gears with the engine running
at high speeds as this may cause
malfunction.
4WD SHIFT SWITCH
● Shift the 4WD shift switch to either the
AUTO, 4H or 4L position, depending on
driving conditions.
● With the switch set to the AUTO position,
distribution of torque to the front and rear
wheels changes automatically, depending
on road conditions encountered [ratio; 0 :
100 (2WD) →50 : 50 (4WD)]. This results in
improved driving stability. ●
If the 4WD shift switch is operated while mak-
ing a turn, accelerating or decelerating or if
the ignition switch is placed in the OFF posi-
tion while in the AUTO, 4H or 4L, you may feel
a jolt. This is not abnormal.
● When the vehicle is stopped after making a
turn, you may feel a slight jolt after the selec-
tor lever is shifted to N (Neutral) or P (Park)
position. This occurs because the transfer
clutch is released and not because of a mal-
function.
CAUTION
● 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 while driv-
ing on steep downhill grades. Use the en-
gine brake and low automatic transmission
gears for engine braking.
● Do not operate the 4WD shift switch with the
rear wheels spinning.
● Before placing the 4WD shift switch in the 4H
position from AUTO, ensure the vehicle
speed is less than 62 MPH (100 km/h). Fail-
ure to do so can damage the 4WD system.
