WARNING AND INDICATOR LIGHTS

.Forcing the front seat or seatback
against an object on the seat or floor
behind it.
. An object placed under the front passen-
ger seat.
. An object placed between the seat
cushion and center console.
If the vehicle is moving, please come to a
stop when it is safe to do so. Check and
correct any of the above conditions. Restart
the vehicle and wait 1 minute.
NOTE:
A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds
initially.
If the light is still OFF after this, the small
adult, child or child restraint should be
repositioned in the rear seat and it is
recommended that the vehicle be checked
by an INFINITI retailer as soon as possible.Other supplemental front-impact
air bag precautions
WARNING
. Do not place any objects on the
steering wheel pad or on the instru-
ment panel. Also, do not place any
objects between any occupant and
the steering wheel or instrument
panel. Such objects may become
dangerous projectiles and cause in-
jury if the front air bags inflate.
. Do not place objects with sharp edges
on the seat. Also, do not place heavy
objects on the seat that will leave
permanent impressions in the seat.
Such objects can damage the seat or
occupant classification sensors
(weight sensors). This can affect the
operation of the air bag system and
result in serious personal injury.
. Do not use water or acidic cleaners
(hot steam cleaners) on the seat. This
can damage the seat or occupant
classification sensors. This can also
affect the operation of the air bag
system and result in serious personal
injury. .
Immediately after inflation, several
front air bag system components will
be hot. Do not touch them; you may
severely burn yourself.
. No unauthorized changes should be
made to any components or wiring of
the supplemental air bag system. This
is to prevent accidental inflation of
the supplemental air bag or damage
to the supplemental air bag system.
. Do not make unauthorized changes
to your vehicle’s electrical system,
suspension system or front end struc-
ture. This could affect proper opera-
tion of the front air bag system.
. Tampering with the air bag system
may result in serious personal injury.
Tampering includes changes to the
steering wheel and the instrument
panel assembly by placing material
over the steering wheel pad and
above the instrument panel or by
installing additional trim material
around the air bag system.
. Removing or modifying the front
passenger seat may affect the func-
tion of the air bag system and result
in serious personal injury.
. Modifying or tampering with the
front passenger seat may result in
serious personal injury. For example,
Safety — seats, seat belts and supplemental restraint system1-63

inflate if the forces in another type of
collision are similar to those of a higher
severity side impact. They are designed to
inflate on the side where the vehicle is
impacted. They may not inflate in certain
side collisions on the side where the vehicle is
impacted.
Curtain air bags are also designed to inflate
in certain types of rollover collisions or near
rollovers. As a result, certain vehicle move-
ments (for example, during severe off road-
ing) may cause the curtain air bags to inflate.
Vehicle damage (or lack of it) is not always
an indication of proper side air bag and
curtain air bag operation.
When side air bags and curtain air bags
inflate, a fairly loud noise may be heard,
followed by release of smoke. This smoke is
not harmful and does not indicate a fire.
Care should be taken not to inhale it, as it
may cause irritation and choking. Those with
a history of a breathing condition should get
fresh air promptly.
Side air bags, along with the use of seat
belts, help to cushion the impact force on the
chest and pelvis of the front occupants.
Curtain air bags help to cushion the impact
force to the head of occupants in the front
and rear (2nd and 3rd) outboard seating
positions. They can help save lives and
reduce serious injuries. However, an inflatingside air bag or curtain air bag may cause
abrasions or other injuries. Side air bags and
curtain air bags do not provide restraint to
the lower body.
The seat belts should be correctly worn and
the driver and passenger seated upright as
far as practical away from the side air bag.
Rear seat passengers should be seated as far
away as practical from the door finishers
and side roof rails. The side air bags and
curtain air bags inflate quickly in order to
help protect the occupants. Because of this,
the force of the side air bags and curtain air
bags inflating can increase the risk of injury if
the occupant is too close to, or is against,
these air bag modules during inflation. In a
rollover, the curtain air bags on both sides
are designed to inflate. Under both side-
impact situations, the curtain air bags will
remain inflated for a short period of time.
The side air bags and curtain air bags
operate only when the ignition switch is in
the ON position.
After pushing the ignition switch to the ON
position, the supplemental air bag warning
light illuminates. The air bag warning light
will turn off after about 7 seconds if the
systems are operational.
WARNING
.
Do not place any objects near the
seatback of the front seats. Also, do
not place any objects (an umbrella,
bag, etc.) between the front door
finisher and the front seat. Such
objects may become dangerous pro-
jectiles and cause injury if side air bag
inflates.
. Right after inflation, several side air
bags and curtain air bag system
components will be hot. Do not touch
them; you may severely burn your-
self.
. No unauthorized changes should be
made to any components or wiring of
side air bag and curtain air bags. This
is to prevent damage to or accidental
inflation of the side air bag and
curtain air bag systems.
. Do not make unauthorized changes
to your vehicle’s electrical system,
suspension system or side panel. This
could affect proper operation of the
side air bag and curtain air bag
systems.
. Tampering with the air bag system
may result in serious personal injury.
For example, do not change the front

alerts the driver to the fact that the VDC
system’s fail-safe mode is operating, for
example the VDC or hill start assist system
may not be functioning properly. Have the
system checked. It is recommended you visit
an INFINITI retailer for this service. If a
malfunction occurs in the system, the VDC
system function will be canceled but the
vehicle is still driveable. For additional
information, see “Vehicle Dynamic Control
(VDC) system” (P.5-124).
INDICATOR LIGHTS
Adaptive Front lighting Sys-
tem (AFS) indicator light (if so
equipped)
When the ignition switch is pushed to the
ON position, the Adaptive Front lighting
System (AFS) indicator light will illuminate.
The light will turn off in about 1 second if the
AFS is operational.
If the AFS indicator light blinks, it may
indicate the AFS is not functioning properly.
Have the system checked. It is recommended
you visit an INFINITI retailer for this service.
See “Adaptive Front lighting System (AFS)”
(P.2-43).
Check suspension indicator
light
When the ignition switch is placed in the ON
position, the light comes on for 2 seconds.
Exterior light indicator
This indicator illuminates when the headlight
switch is turned to the AUTO,orposition and the front parking lights, instru-
ment panel lights, rear combination lights,
license plate lights or headlights are on. The
indicator turns off when these lights are
turned off.
Front fog light indicator light
The front fog light indicator light illuminates
when the front fog lights are on. (See “Fog
light switch” (P.2-45).)
Front passenger air bag status
light
The front passenger air bag status light
() located on the instrument panel will be
lit and the passenger front air bag will be
OFF depending on how the front passenger
seat is being used.
For front passenger air bag status light
operation, see “INFINITI Advanced Air Bag System (front seats)” (P.1-57).
High beam assist indicator
light
The indicator light illuminates when the
headlights come on while the headlight
switch is in the AUTO position with the high
beam selected. This indicates that the high
beam assist system is operational. (See
“High beam assist” (P.2-40).)
High beam indicator light
This light comes on when the headlight high
beam is on and goes out when the low beam
is selected.
Malfunction Indicator Light
(MIL)
If the malfunction indicator light comes on
steady or blinks while the engine is running,
it may indicate a potential emission control
malfunction.
The malfunction indicator light may also
come on steady if the fuel-filler cap is loose
or missing, or if the vehicle runs out of fuel.
Check to make sure the fuel-filler cap is
installed and closed tightly, and that the
vehicle has at least 3 US gallons (14 liters) of
fuel in the fuel tank.
Instruments and controls2-17

.You may feel a pulsation in the brake
pedal and hear a noise or vibration from
under the hood. This is normal and
indicates that the VDC system is working
properly.
. Adjust your speed and driving to the road
conditions.
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system automa-
tically turns off.
The VDC OFF switch is used to turn off the
VDC system. The VDC off indicator
illuminates to indicate the VDC system is off.
When the VDC switch is used to turn off the
system, the VDC system still operates to
prevent one drive wheel from slipping by
transferring power to a non slipping drive
wheel. The VDC warning light
flashes if
this occurs. All other VDC functions are off,
and the VDC warning light
will not flash.
The VDC system is automatically reset to on
when the ignition switch is placed in the off
position then back to the on position.
When the 4L position is selected with the
4WD shift switch, the VDC system is
disabled and the VDC off indicator light
illuminates (for 4WD models).
See “Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-16) and “Vehicle Dynamic
Control (VDC) off indicator light” (P.2-18). The computer has a built-in diagnostic
feature that tests the system each time you
start the engine and move the vehicle
forward or in reverse at a slow speed. When
the self-test occurs, you may hear a “clunk”
noise and/or feel a pulsation in the brake
pedal. This is normal and is not an indication
of a malfunction.
WARNING
.
The VDC system is designed to help
improve driving stability but does not
prevent accidents due to abrupt
steering operation at high speeds or
by careless or dangerous driving
techniques. Reduce vehicle speed
and be especially careful when driving
and cornering on slippery surfaces
and always drive carefully.
. Do not modify the vehicle’s suspen-
sion. If suspension parts such as
shock absorbers, struts, springs, sta-
bilizer bars, bushings and wheels are
not INFINITI recommended for your
vehicle or are extremely deteriorated,
the VDC system may not operate
properly. This could adversely affect
vehicle handling performance, and
the VDC warning light
may
illuminate. .
If brake related parts such as brake
pads, rotors and calipers are not
INFINITI recommended or are extre-
mely deteriorated, the VDC system
may not operate properly and the
VDC warning light
may illumi-
nate.
. If engine control related parts are not
INFINITI recommended or are extre-
mely deteriorated, the VDC warning
light
may illuminate.
. When driving on extremely inclined
surfaces such as higher banked cor-
ners, the VDC system may not oper-
ate properly and the VDC warning
light
may illuminate. Do not drive
on these types of roads.
. When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the VDC warning light
may
illuminate. This is not a malfunction.
Restart the engine after driving onto
a stable surface.
. If wheels or tires other than the
INFINITI recommended ones are
used, the VDC system may not oper-
ate properly and the VDC warning
light
may illuminate.
. The VDC system is not a substitute
for winter tires or tire chains on a

VEHICLE RECOVERY (freeing a
stuck vehicle)
WARNING
.Stand clear of a stuck vehicle.
. Do not spin your tires at high speed.
This could cause them to explode and
result in serious injury. Parts of your
vehicle could also overheat and be
damaged.
Pulling a stuck vehicle
If your vehicle is stuck in sand, snow, mud,
etc., use a tow strap or other device
designed specifically for vehicle recovery.
Always follow the manufacturer’s instruc-
tions for the recovery device.
Attach the tow strap to the towing hook.
CAUTION
.Tow chains or cables must be at-
tached only to the main structural
members of the vehicle or the towing
hooks. Otherwise, the vehicle body
will be damaged. .
Use the towing hook only to free a
vehicle stuck in sand, snow, mud, etc.
Never tow the vehicle for a long
distance using only the towing hook.
. The towing hook is under tremendous
force when used to free a stuck
vehicle. Never pull the hook at an
angle.
. Always pull the cable straight out
from the front or rear of the vehicle.
. Pulling devices should be routed so
they do not touch any part of the
suspension, steering, brake or cooling
systems.
. Pulling devices such as ropes or
canvas straps are not recommended
for use in vehicle towing or recovery.
Rocking a stuck vehicle
If your vehicle is stuck in sand, snow, mud,
etc., use the following procedure:
1. Turn off the Vehicle Dynamic Control
(VDC) system.
2. Make sure the area in front and behind the vehicle is clear of obstructions.
3. Turn the steering wheel right and left to clear an area around the front tires.
4. Slowly rock the vehicle forward and backward.
