Unless checked and repaired, the supplemental
restraint system (air bag system) and/or the
pretensioners may not function properly.
For additional information, see “SUPPLEMENTAL
RESTRAINT SYSTEM” in the “1. Safety — Seats,
seat belts and supplemental restraint system”
section.
WARNING
If the supplemental air bag warning light is on,
it could mean that the front air bag, side air
bag, curtain and rollover air bag systems
and/or pretensioner systems will not operate
in an accident. To help avoid injury to yourself
or others, have your vehicle checked by a re-
tailer as soon as possible.
Vehicle Dynamic Control
(VDC) warning light
The light will blink when the VDC system or the
traction control system is operating, thus alert-
ing the driver that the vehicle is nearing its
traction limits. The road surface may be slip-
pery.
When the vehicle dynamic control warning light
illuminates when the vehicle dynamic control
system is turned on, this light alerts the driver
to the fact that the vehicle dynamic control
system’s fail-safe mode is operating, for ex-
ample the vehicle dynamic control or hill start
assist system may not be functioning properly.
Have the system checked by an INFINITI retailer.
If a malfunction occurs in the system, the
vehicle dynamic control system function will be
canceled but the vehicle is still driveable. For
additional information, see “VEHICLE DYNAMIC
CONTROL (VDC) SYSTEM” in the “5. Starting and
driving” section of this manual.

NOTE:
The approach warning chime may sound and the
system display may blink when the sensor de-
tects some reflectors
Awhich are fitted on ve-
hicles in other lanes or on the side of the road.
This may cause the DCA system to operate inap-
propriately. The sensor may detect these reflec-
tors when the vehicle is driven on winding roads,
hilly roads or when entering or exiting a curve.
The sensor may also detect reflectors on narrow
roads or in road construction zones. In these
cases you will have to manually control the
proper distance ahead of your vehicle. Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driving
position in the lane) or traffic or vehicle condi-
tion (for example, if a vehicle is being driven
with some damage).
Automatic cancellation
Condition A :
Under the following conditions, the Distance
Control Assist system is automatically can-
celed. The chime will sound and the Distance
Control Assist (DCA) system switch indicator
will blink. The system will not be able to be set.

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.

The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to
prevent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on
slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady pres-
sure, but do not pump the brakes. The ABS will
operate to prevent the wheels from locking up.
Steer the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so may
result in increased stopping distances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer.
The computer has a built-in diagnostic feature
that tests the system each time you start the
engine and move the vehicle at a low speed in
forward or reverse. When the self-test occurs,you may hear a “clunk” noise and/or feel a
pulsation in the brake pedal. This is normal and
does not indicate a malfunction. If the computer
senses a malfunction, it switches the ABS off
and illuminates the ABS warning light on the
instrument panel. The brake system then oper-
ates normally, but without anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by an INFINITI retailer.
Normal operation
The ABS operates at speeds above 3 to 6 MPH
(5 to 10 km/h). The speed varies according to
road conditions.
When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly
applies and releases hydraulic pressure. This
action is similar to pumping the brakes very
quickly. You may feel a pulsation in the brake
pedal and hear a noise from under the hood or
feel a vibration from the actuator when it is
operating. This is normal and indicates that the
ABS is operating properly. However, the pulsa-
tion may indicate that road conditions are haz-
ardous and extra care is required while driving.
The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and
vehicle motion. Under certain driving condi-
tions, the VDC system helps to perform the
following functions.
●
Controls brake pressure to reduce wheel slip
on one slipping drive wheel so power is
transferred to a non slipping drive wheel on
the same axle.
● Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function).
● Controls brake pressure at individual wheels
and engine output to help the driver main-
tain control of the vehicle in the following
conditions:
– understeer (vehicle tends to not follow the steered path despite increased steer-
ing input)
– oversteer (vehicle tends to spin due to certain road or driving conditions).
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss
of vehicle control in all driving situations.
