2011 INFINITI QX wiring

If an adult occupant is in the seat but the
passenger air bag status light is illuminated
(indicating that the air bag is OFF), it could be
that the person is a small adult, or is not sitting
on the seat properly.
If a child restraint must be used in the front
seat, the passenger air bag status light may or
may not be illuminated, depending on the size
of the child and the type of child restraint being
used. If the passenger air bag status light is not
illuminated (indicating that the air bag might
inflate in a crash), it could be that the child
restraint or seat belt is not being used properly.
Make sure that the child restraint is installed
properly, the seat belt is used properly and the
occupant is positioned properly. If the passen-
ger air bag status light is still not illuminated,
reposition the occupant or child restraint in a
rear seat.
If the passenger air bag status light will not
illuminate even though you believe that the
child restraint, the seat belts and the occupant
are properly positioned, the system may be
sensing an unoccupied seat (in which case the
air bag is OFF). Your INFINITI retailer can check
that the system is OFF by using a special tool.
However, until you have confirmed with your
retailer that your air bag is working properly,
reposition the occupant or child restraint in a
rear seat.The INFINITI Advanced Air Bag System and
passenger air bag status light will take a few
seconds to register a change in the passenger
seat status. However, if the seat becomes un-
occupied, the air bag status light will remain
off.
If a malfunction occurs in the front passenger
air bag system, the supplemental air bag warn-
ing light
, located in the meter and
gauges area will blink. Have the system
checked by an INFINITI retailer.
Other supplemental front-impact air
bag precautions
WARNING
● Do not place any objects on the steering
wheel pad or on the instrument panel. Also,
do not place any objects between any occu-
pant and the steering wheel or instrument
panel. Such objects may become dangerous
projectiles and cause injury 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 opera-
tion of the air bag system and result in seri-
ous personal injury.
● Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can dam-
age the seat or occupant classification sen-
sors. 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 supplemen-
tal air bag system. This is to prevent acciden-
tal 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 sys-
tem or front end structure. This could affect
proper operation of the front air bag system.
Safety — Seats, seat belts and supplemental restraint system1-59

●Tampering with the air bag system may re-
sult 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.
● Modifying or tampering with the front pas-
senger seat may result in serious personal
injury. For example, do not change the front
seats by placing material on the seat cush-
ion or by installing additional trim material,
such as seat covers, on the seat that is not
specifically designed to assure proper air
bag operation. Additionally, do not stow any
objects under the front passenger seat or the
seat cushion and seatback. Such objects
may interfere with the proper operation of
the occupant classification sensors.
● No unauthorized changes should be made to
any components or wiring of the seat belt
system. This may affect the front air bag
system. Tampering with the seat belt system
may result in serious personal injury. ●
Work on and around the front air bag system
should be done by an INFINITI retailer. Instal-
lation of electrical equipment should also be
done by an INFINITI retailer. The Supplemen-
tal Restraint System (SRS) wiring har-
nesses* should not be modified or discon-
nected. Unauthorized electrical test
equipment and probing devices should not
be used on the air bag system.
● A cracked windshield should be replaced im-
mediately by a qualified repair facility. A
cracked windshield could affect the function
of the supplemental air bag system.
*1.The SRS wiring harness connectors are yellow and orange for easy identifica-
tion.
When selling your vehicle, we request that you
inform the buyer about the front air bag system
and guide the buyer to the appropriate sections
in this Owner’s Manual.
FRONT SEAT-MOUNTED SIDE-IMPACT
SUPPLEMENTAL AIR BAG AND
ROOF-MOUNTED CURTAIN SIDE-
IMPACT AND ROLLOVER
SUPPLEMENTAL AIR BAG SYSTEMS
The side air bags are located in the outside of
the seatback of the front seats. The curtain and
rollover air bags are located in the side roof
rails. These systems are designed to meet
voluntary guidelines to help reduce the risk of
injury to out-of-position occupants. However, all
of the information, cautions and warnings in this
manual still apply and must be followed. The
side air bags and curtain and rollover air bags
are designed to inflate in higher severity side
SSS1092
1-60Safety — Seats, seat belts and supplemental restraint system

collisions, although they may 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 and rollover air bags are also designed
to inflate in certain types of rollover collisions
or near rollovers. As a result, certain vehicle
movements (for example, during severe off
roading) may cause the curtain and rollover air
bags to inflate.
Vehicle damage (or lack of it) is not always an
indication of proper side air bag and curtain
and rollover air bag operation.
When side air bags and curtain and rollover 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 and
rollover air bags help to cushion the impact
force to the head of occupants in the front andrear (2nd and 3rd) outboard seating positions.
They can help save lives and reduce serious
injuries. However, an inflating side air bags and
curtain and rollover air bags may cause abra-
sions or other injuries. Side air bags and curtain
and rollover 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 and rollover
air bags inflate quickly in order to help protect
the occupants. Because of this, the force of the
side air bags and curtain and rollover 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. The side air bags
will deflate quickly after the collision is over.
The curtain and rollover air bag will remain
inflated for a while.
The side air bags and curtain and rollover air
bags operate only when the ignition switch is in
the ON position.
After pushing the ignition switch to the ON posi-
tion, the supplemental air bag warning light illu-
minates. The air bag warning light will turn off
after about 7 seconds if the systems are opera-
tional.
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 projectiles
and cause injury if side air bag inflates.
● Right after inflation, several side air bags
and curtain and rollover air bag system com-
ponents will be hot. Do not touch them; you
may severely burn yourself.
● No unauthorized changes should be made to
any components or wiring of side air bag and
curtain and rollover air bags. This is to pre-
vent damage to or accidental inflation of the
side air bag and curtain and rollover air bag
systems.
● Do not make unauthorized changes to your
vehicle’s electrical system, suspension sys-
tem or side panel. This could affect proper
operation of the side air bag and curtain and
rollover air bag systems.
Safety — Seats, seat belts and supplemental restraint system1-61

●Tampering with the air bag system may re-
sult in serious personal injury. For example,
do not change the front seats by placing
material near the seatback or by installing
additional trim material, such as seat cov-
ers, around the side air bags.
● Work around and on the side air bag and
curtain and rollover air bag systems should
be done by an INFINITI retailer. Installation
of electrical equipment should also be done
by an INFINITI retailer. The Supplemental Re-
straint System (SRS) wiring harnesses*
should not be modified or disconnected. Un-
authorized electrical test equipment and
probing devices should not be used on the
side-impact air bag system.
*1.The SRS wiring harness connectors are yellow and orange for easy identifica-
tion.
When selling your vehicle, we request that you
inform the buyer about the side air bag and
curtain and rollover air bag systems and guide
the buyer to the appropriate sections in this
Owner’s Manual.
SEAT BELTS WITH PRETENSIONERS
(front seats)
WARNING
●The pretensioners cannot be reused after ac-
tivation. They must be replaced together
with the retractor and buckle as a unit.
● If the vehicle becomes involved in a frontal,
side impact and rollover collision but a pre-
tensioner is not activated, be sure to have
the pretensioner system checked and, if nec-
essary, replaced by an INFINITI retailer.
● No unauthorized changes should be made to
any components or wiring of the preten-
sioner system. This is to prevent damage to
or accidental activation of the pretension-
ers. Tampering with the pretensioner sys-
tem may result in serious personal injury.
● Work around and on the pretensioner sys-
tem should be done by an INFINITI retailer.
Installation of electrical equipment should
also be done by an INFINITI retailer. Unau-
thorized electrical test equipment and prob-
ing devices should not be used on the pre-
tensioner system. ●
If you need to dispose of a pretensioner or
scrap the vehicle, contact an INFINITI re-
tailer. Correct pretensioner disposal proce-
dures are set forth in the appropriate
INFINITI Service Manual. Incorrect disposal
procedures could cause personal injury.
The pre-tensioner system activates when any of
the air bags deploy. Working with the seat belt
retractor, it helps tighten the seat belt when the
vehicle becomes involved in certain types of
collisions, helping to restrain front seat occu-
pants.
The pretensioner is encased with the seat belt
retractor and buckle anchor. These seat belts
are used the same way as conventional seat
belts.
When a pretensioner activates, smoke is re-
leased and a loud noise may be heard. The
smoke is not harmful, and it 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.
After pretensioner activation, load limiters al-
low the seat belt to release webbing (if neces-
sary) to reduce forces against the chest.
1-62Safety — Seats, seat belts and supplemental restraint system

If any abnormality occurs in the pretensioner
system, the supplemental air bag warning light
will not come on, will flash intermittently
or will turn on for 7 seconds and remain on after
the ignition switch has been pushed to the ON
position. In this case, the pretensioner system
may not function properly. They must be
checked and repaired. Take your vehicle to the
nearest INFINITI retailer.
When selling your vehicle, we request that you
inform the buyer about the pretensioner system
and guide the buyer to the appropriate sections
in this Owner’s Manual.

WARNING
●Do not leave children or adults who would
normally require the support of others alone
in your vehicle. Pets should not be left alone
either. They could accidentally injure them-
selves or others through inadvertent opera-
tion of the vehicle. Also, on hot, sunny days,
temperatures in a closed vehicle could
quickly become high enough to cause severe
or possibly fatal injuries to people or
animals.
● Properly secure all cargo to help prevent it
from sliding or shifting. Do not place cargo
higher than the seatbacks. In a sudden stop
or collision, unsecured cargo could cause
personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
● Do not breathe exhaust gases; they contain
colorless and odorless carbon monoxide.
Carbon monoxide is dangerous. It can cause
unconsciousness or death.
● If you suspect that exhaust fumes are enter-
ing the vehicle, drive with all windows fully
open, and have the vehicle inspected
immediately. ●
Do not run the engine in closed spaces such
as a garage.
● Do not park the vehicle with the engine run-
ning for any extended length of time.
● Keep the lift gate closed while driving, oth-
erwise exhaust gases could be drawn into
the passenger compartment. If you must
drive with the lift gate open, follow these
precautions:
1) Open all the windows.
2) Set the
air recirculation to off and
the fan control to high to circulate the air.
● If electrical wiring or other cable connec-
tions must pass to a trailer through the seal
on the lift gate or the body, follow the manu-
facturer’s recommendation to prevent car-
bon monoxide entry into the vehicle.
● The exhaust system and body should be in-
spected by a qualified mechanic whenever:
– The vehicle is raised for service.
– You suspect that exhaust fumes are en- tering into the passenger compartment.
– You notice a change in the sound of the exhaust system. – You have had an accident involving dam-
age to the exhaust system, underbody, or
rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
WARNING
●The exhaust gas and the exhaust system are
very hot. Keep people, animals or flammable
materials away from the exhaust system
components.
● Do not stop or park the vehicle over flam-
mable materials such as dry grass, waste
paper or rags. They may ignite and cause a
fire.
PRECAUTIONS WHEN STARTING AND
DRIVING
5-2Starting and driving

3. Try to rearrange the trailer load so it isbalanced as described earlier in this sec-
tion.
●Be careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal pass-
ing. Remember the length of the trailer must
also pass the other vehicle before you can
safely change lanes.
● Use the Tow mode or downshift the trans-
mission to a lower gear for engine braking
when driving down steep or long hills. This
will help slow the vehicle without applying
the brakes.
● Avoid holding the brake pedal down too long
or too frequently. This could cause the
brakes to overheat, resulting in reduced
braking efficiency.
● Increase your following distance to allow for
greater stopping distances while towing a
trailer. Anticipate stops and brake gradually.
● INFINITI recommends that the cruise control
not be used while towing a trailer. ●
While towing a trailer, do not use the follow-
ing systems (if so equipped):
– the Lane Departure Prevention (LDP) sys- tem
– the Blind Spot Warning (BSW) system
– the Intelligent Cruise Control (ICC) system
– the Distance Control Assist (DCA) system
– Intelligent Brake Assist ( IBA) system
● Some states or provinces have specific regu-
lations and speed limits for vehicles that are
towing trailers. Obey the local speed limits.
● Check your hitch, trailer wiring harness con-
nections, and trailer wheel lug nuts after 50
miles (80 km) of travel and at every break.
● When launching a boat, do not allow the
water level to go over the exhaust tail pipe or
rear bumper.
● Make sure you disconnect the trailer lights
before backing the trailer into the water or
the trailer lights may burn out.
When towing a trailer, the transmission fluid
should be changed more frequently. For addi-
tional information, see the INFINITI Service and
Maintenance Guide.
TOW mode
Using TOW mode is recommended when pulling
a heavy trailer or hauling a heavy load. Push the
TOW MODE switch to activate tow mode. The
TOW MODE indicator light in the meter illumi-
nates when TOW mode is selected. Push the
TOW MODE switch again to turn TOW mode off.
TOW mode is automatically cancelled when the
ignition switch is placed in the OFF position.
TOW mode includes the following features:
● Grade logic — Adjusts transmission shifts
when pulling a trailer or hauling a load up a
grade.
● Downhill Speed Control (DSC) — automati-
cally downshifts when driving down a grade
with a trailer or heavy load to help control
vehicle speed.
Driving the vehicle in the TOW mode with no
trailer/load or light trailer/light load will not
cause any damage. However, fuel economy may
be reduced and the transmission/engine driv-
ing characteristics may feel unusual.
When towing a trailer, final drive gear oil should
be replaced and transmission oil/fluid should be
changed more frequently. For additional infor-
mation, see the 9. “Technical and consumer in-
formation” section later in this manual.
