2011 INFINITI QX service

Your INFINITI represents a new way of thinking
about vehicle design. It integrates advanced
engineering and superior craftsmanship with a
simple, refined aesthetic sensitivity associated
with traditional Japanese culture.
The result is a different notion of luxury and
beauty. The car itself is important, but so is the
sense of harmony that the vehicle evokes in its
driver, and the sense of satisfaction you feel
with the INFINITI — from the way it looks and
drives to the high level of retailer service.
To ensure that you enjoy your INFINITI to the
fullest, we encourage you to read this Owner’s
Manual immediately. It explains all of the fea-
tures, controls and performance characteristics
of your INFINITI; it also provides important
instructions and safety information.
A separate Warranty Information Booklet is in-
cluded in your Owner’s literature portfolio. The
INFINITI Service and Maintenance Guide ex-
plains details about maintaining and servicing
your vehicle. Always carry it with you when you
take your vehicle to an INFINITI retailer. The War-
ranty Information Booklet contents provide
complete information about all warranties cov-
ering this vehicle, the requirements to keep the
warranties in effect as well as the INFINITI Road-
side Assistance program.Additionally, a separate Customer Care and
Lemon Law Information Booklet will explain how
to resolve any concerns you may have with your
vehicle, as well as clarify your rights under your
state’s lemon law.
READ FIRST — THEN DRIVE SAFELY
Before driving your vehicle, read your Owner’s
Manual carefully. This will ensure familiarity
with controls and maintenance requirements,
assisting you in the safe operation of your

●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

When the ignition switch is in the ON position,
the supplemental air bag warning light illumi-
nates for about 7 seconds and then turns off.
This means the system is operational.
If any of the following conditions occur, the
front air bag, side air bag, curtain and rollover
air bag and pretensioner systems need servic-
ing:
●The supplemental air bag warning light re-
mains on approximately 7 seconds after the
ignition switch is pushed to the ON position.
● The supplemental air bag warning light
flashes intermittently.
● The supplemental air bag warning light does
not come on at all.
Under these conditions, the front air bag, side
air bags, and curtain and rollover air bags or
pretensioner systems may not operate properly.
They must be checked and repaired. Take your
vehicle to the nearest INFINITI retailer.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 and/or preten-
sioner systems will not operate in an accident.
To help avoid injury to yourself or others, have
your vehicle checked by a retailer as soon as
possible.
REPAIR AND REPLACEMENT
PROCEDURE
The front air bags, side air bags, curtain and
rollover air bags and pretensioners are de-
signed to activate on a one-time-only basis. As
a reminder, unless it is damaged, the supple-
mental air bag warning light will remain illumi-
nated after inflation has occurred. Repair and
replacement of these systems should be done
only by an INFINITI retailer.
When maintenance work is required on the
vehicle, the front air bags, side air bags, curtain
and rollover air bags, pretensioners and related
parts should be pointed out to the person
conducting the maintenance. The ignition
switch should always be in the LOCK position
when working under the hood or inside the
vehicle.
WARNING
● Once a front air bag, side air bag or curtain
and rollover air bag has inflated, the air bag
module will not function again and must be
replaced. Additionally, the activated preten-
sioner must also be replaced. The air bag
module and pretensioner should be replaced
by an INFINITI retailer. The air bag module
and pretensioner system cannot be
repaired.
● The front air bag, side air bag, curtain and
rollover air bag and the pretensioner should
be inspected by an INFINITI retailer if there is
any damage to the front end or side portion
of the vehicle.
● If you need to dispose of a supplemental air
bag or pretensioner or scrap the vehicle,
contact an INFINITI retailer. Correct supple-
mental air bag and pretensioner system dis-
posal procedures are set forth in the appro-
priate INFINITI Service Manual. Incorrect
disposal procedures could cause personal
injury.

CAUTION
Continued vehicle operation when the AT oil
temperature warning light is on may damage
the AT.
orBrake warning
light
This light functions for both the parking brake
and the foot brake systems.
Parking brake indicator :
When the ignition switch is in the ON position,
the light comes on when the parking brake is
applied.
Low brake fluid warning light :
When the ignition switch is in the ON position,
the light warns of a low brake fluid level. If the
light comes on while the engine is running with
the parking brake not applied, stop the vehicle
and perform the following:
1. Check the brake fluid level. If brake fluid isnecessary, add fluid and have the system
checked by your INFINITI retailer. (See
“BRAKE FLUID” in the “8. Maintenance
and do-it-yourself” section.) 2. If the brake fluid level is correct, have the
warning system checked by an INFINITI
retailer.
Low hydraulic pressure warning indicator :
If the brake warning light illuminates when the
engine is running, or while driving with the
parking brake is released, check the brake fluid
level. If the brake fluid level is sufficient, it may
indicate low hydraulic pressure in the brake
booster. Have the brake system checked by an
INFINITI retailer promptly.
Anti-lock Braking System (ABS) warning indica-
tor :
When the parking brake is released and the
brake fluid level is sufficient, if both the brake
warning light and the Anti-lock Braking System
(ABS) warning light illuminate, it may indicate
the ABS is not functioning properly. Have the
brake system checked, and if necessary re-
paired, by an INFINITI retailer promptly. (See
“Anti-lock Braking System (ABS) warning light”
earlier in this section.)
WARNING
●Your brake system may not be working prop-
erly if the warning light is on. Driving could
be dangerous. If you judge it to be safe, drive
carefully to the nearest service station for
repairs. Otherwise, have your vehicle towed
because driving it could be dangerous.
● Pressing the brake pedal with the engine
stopped and/or low brake fluid level may
increase your stopping distance and braking
will require greater pedal effort as well as
pedal travel.
● If the brake fluid level is below the minimum
or MIN mark on the brake fluid reservoir, do
not drive until the brake system has been
checked at an INFINITI retailer.
Blind Spot Warning (BSW)
system warning light

If the light comes on in orange and remains on,
it may indicate that the BSW system is not
functioning properly. Although the vehicle is
still driveable, have the system checked by an
INFINITI retailer. See “BLIND SPOT WARNING
(BSW) SYSTEM” in the “5. Starting and driving”
section.

OPERATING TIPS
When the engine coolant temperature and out-
side air temperature are low, the air flow from
the foot outlets may not operate. However, this
is not a malfunction. After the coolant tempera-
ture warms up, the air flow from the foot outlets
will operate normally.
The sensors
AandBlocated on the instru-
ment panel help maintain a constant tempera-
ture. Do not put anything on or around the
sensors.
IN-CABIN MICROFILTER
Models without Advanced Climate Control Sys-
tem:
The climate control system is equipped with an
in-cabin microfilter which collects dirt, pollen,
dust, etc. To make sure the air conditioner
heats, defogs, and ventilates efficiently, replace
the filter in accordance with the maintenance
schedule in the INFINITI Service and Mainte-
nance Guide. To replace the filter, contact an
INFINITI retailer.
The filter should be replaced if air flow is ex-
tremely decreased or when windows fog up eas-
ily when operating heater or air conditioning
system. Models with Advanced Climate Control System:
The climate control system is equipped with a
natural grape seed polyphenol filter which col-
lects and neutralizes dirt, pollen, dust, etc. To
make sure that the air conditioner heats, defogs
and ventilates efficiently, replace the filter in
accordance with the maintenance schedule in
the INFINITI Service and Maintenance Guide. To
replace the filter, contact an INFINITI retailer.
The filter should be replaced if the air flow de-
creases significantly or if windows fog up easily
when operating the heater or air conditioner.SAA3088
