PRECAUTIONS ON CRUISE
CONTROL
.If the cruise control system malfunctions,
it will cancel automatically. The SET
indicator on the vehicle information dis-
play will then blink to warn the driver.
. If the engine coolant temperature be-
comes excessively high, the cruise con-
trol system will be canceled
automatically.
. If the SET indicator blinks, turn the cruise
control main switch off and have the
system checked. It is recommended you
visit an INFINITI retailer for this service.
. The SET indicator may sometimes blink
when the cruise control main switch is
turned ON while pushing the COAST/
SET, ACCELERATE/RESUME or CAN-
CEL switch. To properly set the cruise
control system, perform the steps below
in the order indicated.
WARNING
Do not use the cruise control when
driving under the following conditions:
. when it is not possible to keep the
vehicle at a set speed .
in heavy traffic or in traffic that
varies in speed
. on winding or hilly roads
. on slippery roads (rain, snow, ice,
etc.)
. in very windy areas
Doing so could cause a loss of vehicle
control and result in an accident.

WARNING
Failure to follow the warnings and
instructions for proper use of the DCA
system could result in serious personal
injury or death.
.Always drive carefully and atten-
tively when using the DCA system.
Read and understand the Owner’s
Manual thoroughly before using the
DCA system. To avoid serious injury
or death, do not rely on the system to
prevent accidents or to control the
vehicle’s speed in emergency situa-
tions. Do not use the DCA system
except in appropriate road and traffic
conditions.
. This system is only an aid to assist the
driver and is not a collision warning or
avoidance device. It is the driver’s
responsibility to stay alert, drive
safely and be in control of the vehicle
at all times.
. As there is a performance limit to the
distance control function, never rely
solely on the DCA system. This sys-
tem does not correct careless, inat-
tentive or absent-minded driving, or
overcome poor visibility in rain, fog,
or other bad weather. Decelerate the
DISTANCE CONTROL ASSIST
(DCA) (if so equipped)

.When the VDC or ABS (including the
traction control system) operates
. When the INFINITI Drive Mode Selector
is turned to the SNOW mode (To use the
DCA system, turn the INFINITI Drive
Mode Selector to a mode other than the
SNOW mode, then turn on the dynamic
driver assistance switch
.)
For details about the INFINITI Drive
Mode Selector, see “INFINITI Drive
Mode Selector” (P.5-20).

interrupted
Action to take:
When the conditions listed above are no
longer present, turn the system off with the
dynamic driver assistance switch
. Turn the

SYSTEM MAINTENANCE
The sensor for the DCA systemis located
behind the lower grille of the front bumper.
The DCA system is designed to automati-
cally check the sensor’s operation. When the
sensor is covered with dirt or is obstructed,
the system will automatically be canceled. If
the sensor is covered with ice, a transparent
or translucent vinyl bag, etc., the DCA
system may not detect them. In these
instances, the DCA system may not be able
to decelerate the vehicle properly. Be sure to
check and clean the sensor regularly.
To keep the DCA system operating properly,
be sure to observe the following:

The AWD warning light is located in the
meter.
The AWD warning light comes on when the
ignition switch is pushed to the ON position.
It turns off soon after the engine is started.
If any malfunction occurs in the Intelligent
AWD system while the engine is running, thewarning light will come on.
The warning light may blink rapidly (about
twice per second) while trying to free a stuck
vehicle due to high power train oil tempera-
ture. The driving mode may change to two-
wheel drive. If the warning light blinks
rapidly during operation, stop the vehicle
with the engine idling in a safe place
immediately. 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). Pull off the road in a safe area,
and idle the engine. Check that all tire sizes
are the same, tire pressure is correct and
tires are not worn.
If the warning light is blinking after the
above operation, have your vehicle checked
as soon as possible. It is recommended you
visit an INFINITI retailer for this service.WARNING
.
For AWD equipped vehicles, 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 an AWD
equipped vehicle on a 2-wheel dy-
namometer (such as the dynam-
ometers used by some states for
emissions testing) or similar equip-
ment even if the other two wheels are
raised off the ground. Make sure that
you inform the test facility personnel
that your vehicle is equipped with
AWD before it is placed on a dynam-
ometer. Using the wrong test equip-
ment may result in drivetrain damage
or unexpected vehicle movement
which could result in serious vehicle
damage or personal injury.
CAUTION
.Do not operate the engine on a free
roller when any of the wheels are
raised.
. If the warning light comes on while
driving there may be a malfunction in
the AWD system. Reduce the vehicle
speed and have your vehicle checked
as soon as possible. It is recom-
mended you visit an INFINITI retailer
for this service.
