2010 INFINITI QX four wheel drive

For descriptions specified for four-wheel drive
models, amark is placed at the begin-
ning of the applicable sections/items.
As with other vehicles with features for
off-road use, failure to operate four-wheel
drive models correctly may result in loss of
control or an accident. Be sure to read
“Driving safety precautions” in the “Start-
ing and driving” section of this manual.
ON-PAVEMENT AND OFF-ROAD
DRIVING
This vehicle will handle and maneuver
differently from an ordinary passenger
car because it has a higher center of
gravity for off-road use. As with other
vehicles with features of this type, fail-
ure to operate this vehicle correctly may
result in loss of control or an accident.
Be sure to read “On-pavement and off-
road driving precautions”, and “Avoid-
ing collision and rollover”, and “Driving
safety precautions”, in the “Starting and
driving” section of this manual.

When the low tire pressure warning light
illuminates, you should stop and adjust the
tire pressure of all 4 tires to the recom-
mended COLD tire pressure shown on the
Tire and Loading Information label located
in the driver’s door opening. The low tire
pressure warning light does not automati-
cally turn off when the tire pressure is ad-
justed. After the tire is inflated to the rec-
ommended pressure, the vehicle must be
driven at speeds above 16 MPH (25 km/h)
to activate the TPMS and turn off the low
tire pressure warning light. Use a tire pres-
sure gauge to check the tire pressure.
For additional information, see “Tire Pressure
Monitoring System (TPMS)” in the “Starting and
driving” section and in the “In case of emergency”
section.
TPMS malfunction:
If the TPMS is not functioning properly, the low
tire pressure warning light will flash for approxi-
mately 1 minute when the ignition switch is
turned ON. The light will remain on after the 1
minute. Have the system checked by an INFINITI
dealer.
For additional information, see “Tire Pressure
Monitoring System (TPMS)” in the “Starting and
driving” section and “Tire pressure” in the “Main-
tenance and do-it-yourself” section.WARNING
●If the light does not illuminate with the
ignition switch turned ON, have the ve-
hicle checked by an INFINITI dealer as
soon as possible.
● If the light illuminates while driving,
avoid sudden steering maneuvers or
abrupt braking, reduce vehicle speed,
pull off the road to a safe location and
stop the vehicle as soon as possible.
Driving with under-inflated tires may
permanently damage the tires and in-
crease the likelihood of tire failure. Se-
rious vehicle damage could occur and
may lead to an accident and could re-
sult in serious personal injury. Check
the tire pressure for all four tires. Adjust
the tire pressure to the recommended
COLD tire pressure shown on the Tire
and Loading Information label located
in the driver’s door opening to turn the
low tire pressure warning light OFF. If
the light still comes on while driving
after adjusting the tire pressure, a tire
may be flat. If you have a flat tire, re-
place it with a spare tire as soon as
possible. ●
When a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI dealer as soon as
possible for tire replacement and/or
system resetting.
● Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
CAUTION
● The TPMS is not a substitute for the
regular tire pressure check. Be sure to
check the tire pressure regularly.
● If the vehicle is being driven at speeds
of less than 16 MPH (25 km/h) , the
TPMS may not operate correctly.
● Be sure to install the specified size of
tires to the 4 wheels correctly.
Master warning light
This light comes on when various vehicle infor-
mation display warnings appear.

Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction indicator is
illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons,
including the installation of replacement or alter-
nate tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replac-
ing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.Additional information:
● This system does not monitor the tire
pressure of the spare tire.
● The low tire pressure warning system will
activate only when the vehicle is driven at
speeds above 16 MPH (26 km/h) . Also, this
system may not detect a sudden drop in tire
pressure (for example a flat tire while driv-
ing) .
● The low tire pressure warning light does not
automatically turn off when the tire pressure
is adjusted. After all 4 tires are inflated to the
recommended pressure, the vehicle must be
driven at speeds above 16 MPH (25 km/h)
to activate the TPMS and turn off the low tire
pressure warning light. Use a tire pressure
gauge to check the tire pressure.
● Tire pressure rises and falls depending on
the heat caused by the vehicle’s operation
and the outside temperature. Low outside
temperature can lower the temperature of
the air inside the tire which can cause a
lower tire inflation pressure. This may cause
the low tire pressure warning light to illumi-
nate. If the warning light illuminates in low
ambient temperature, check the tire pres-
sure for all four tires. ●
The Tire and Loading Information label (also
referred to as the vehicle placard or tire
inflation pressure label) is located in the
driver’s door opening.
● You can also check the pressure of all tires
(except the spare tire) on the display screen.
The order of the tire pressure figures dis-
played on the screen does not correspond
with the actual order of the tire position. See
“Tire pressure information” in the “Monitor,
climate, audio, phone and voice recognition
systems” section.
For additional information, see “Low tire pressure
warning light” in the “Instruments and controls”
section and “Tire pressure monitoring system” in
the “In case of emergency” section.

WARNING
The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air pressure.
Losing control of the vehicle may cause a
collision and result in personal injury.
●The vehicle generally moves or pulls in
the direction of the flat tire.
● Do not rapidly apply the brakes.
● Do not rapidly release the accelerator
pedal.
● Do not rapidly turn the steering wheel.
1. Remain calm and do not over react.
2. Maintain a firm grip on the steering wheel with both hands and try to hold a straight
course.
3. When appropriate, slowly release the accel- erator pedal to gradually slow the vehicle.
4. Gradually steer the vehicle to a safe location off the road and away from traffic if possible.
5. Lightly apply the brake pedal to gradually stop the vehicle. 6. Turn on the hazard warning flashers and
either contact a roadside emergency service
to change the tire or see “Changing a flat
tire” in the “In case of emergency” section of
this manual.
DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of alcohol
or drugs. Alcohol in the bloodstream re-
duces coordination, delays reaction time
and impairs judgement. Driving after
drinking alcohol increases the likelihood
of being involved in an accident injuring
yourself and others. Additionally, if you
are injured in an accident, alcohol can
increase the severity of the injury.
INFINITI is committed to safe driving. However,
you must choose not to drive under the influence
of alcohol. Every year thousands of people are
injured or killed in alcohol-related accidents. Al-
though the local laws vary on what is considered
to be legally intoxicated, the fact is that alcohol
affects all people differently and most people
underestimate the effects of alcohol. Remember, drinking and driving don’t mix! And
that is true for drugs, too (over-the-counter, pre-
scription, and illegal drugs) . Don’t drive if your
ability to operate your vehicle is impaired by alco-
hol, drugs, or some other physical condition.
DRIVING SAFETY PRECAUTIONS
Your INFINITI is designed for both normal and
off-road use. However, avoid driving in deep wa-
ter or mud as your INFINITI is mainly designed for
leisure use, unlike a conventional off-road ve-
hicle.
Remember that two-wheel drive models are less
capable than four-wheel drive models for rough
road driving and extrication when stuck in deep
snow or mud, or the like.
Please observe the following precautions:
WARNING
●
Drive carefully when off the road and
avoid dangerous areas. Every person
who drives or rides in this vehicle
should be seated with their seat belt
fastened. This will keep you and your
passengers in position when driving
over rough terrain.

●If at all possible, avoid sharp turning
maneuvers, particularly at high speeds.
Your INFINITI four-wheel drive vehicle
has a higher center of gravity than a
passenger car. The vehicle is not de-
signed for cornering at the same
speeds as passenger cars. Failure to
operate this vehicle correctly could re-
sult in loss of control and/or a rollover
accident.
● Always use tires of the same type, size,
brand, construction (bias, bias-belted,
or radial) , and tread pattern on all four
wheels. Install tire chains on the rear
wheels when driving on slippery roads
and drive carefully.
● Be sure to check the brakes immedi-
ately after driving in mud or water. See
“Brake system” later in this section for
“Wet brakes”.
● Avoid parking your vehicle on steep
hills. If you get out of the vehicle and it
rolls forward, backward or sideways,
you could be injured. ●
Whenever you drive off-road through
sand, mud or water as deep as the
wheel hub, more frequent maintenance
may be required. See “Periodic mainte-
nance” in the “INFINITI Service and
Maintenance Guide.”WARNING
● Never remove the key or turn the igni-
tion switch to the LOCK position while
driving. The steering wheel will lock.
This may cause the driver to lose con-
trol of the vehicle and could result in
serious vehicle damage or personal
injury.
● Never turn the ignition switch to the
LOCK position while driving. The steer-
ing wheel will lock. This may cause the
driver to lose control of the vehicle and
could result in serious vehicle damage
or personal injury.

●When cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag.
● For vehicles equipped with
, use 4H or
4L position only when necessary. Four-
wheel drive operation lowers fuel economy.
WARNING
● For 4WD equipped vehicles, do not at-
tempt 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 ve-
hicle movement which could result in
serious vehicle damage or personal
injury.
● Do not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer
(such as the dynamometers used by
some states for emissions testing) , or
similar equipment even if the other two
wheels are raised off the ground. Make
sure you inform test facility personnel
that your vehicle is equipped with 4WD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or per-
sonal injury.
CAUTION
● Do not drive the vehicle in the 4H or 4LO
position on dry hard surface roads. Driv-
ing on dry, hard surfaces in 4H or 4LO
may cause unnecessary noise, tire wear
and increased fuel consumption.
If the 4WD warning light turns on when
you are driving on dry hard surface
roads:
– in the 4H position, shift the 4WD shift switch to 2WD.
– in the 4LO position, stop the vehicle, move the automatic transmission
shift selector to the N position and
shift the 4WD shift switch to 2WD
● If the warning light is still on after the
above operation, have your vehicle
checked by an INFINITI dealer as soon
as possible.
● The transfer case may be damaged if
you continue driving with the warning
light blinking.

Owners Manual (owners)—USA_English (nna)
02/13/09—tbrooks


The transfer case 4WD shift switch is used to
select either 2WD or 4WD depending on the
driving conditions. There are four types of drive
modes available, AUTO, 2WD, 4H and 4LO.
The 4WD shift switch electronically controls the
transfer case operation. Rotate the switch to
move between each mode, 2WD, AUTO, 4H and
4LO.
You must push the switch in to select 4LO,
and the vehicle MUST be stationary and the
shift selector in the N position when chang-
ing into or out of 4LO.
WARNING
When parking, apply the parking brake
before stopping the engine and make sure
that the 4WD shift indicator light is on and
the ATP warning light goes off. Otherwise,
the vehicle could unexpectedly move even
if the automatic transmission is in the P
position.
CAUTION
●Never shift the 4WD shift switch be-
tween 4LO and 4H while driving.
● The 4H position provides greater trac-
tion. Avoid excessive speed, as it will
cause increased fuel consumption and
higher oil temperatures, and could
damage drivetrain components.
Speeds over 62 MPH (100 km/h) in 4H is
not recommended.
● The 4LO position provides maximum
power and traction. Avoid raising ve-
hicle speed excessively, as the maxi-
mum speed is approximately 31 MPH
(50 km/h) .
● When driving straight, shift the 4WD
shift switch to the 2WD, AUTO or 4H
position. Do not move the 4WD shift
switch when making a turn or reversing.
● Do not shift the 4WD shift switch (be-
tween 2WD, AUTO and 4H) while driving
on steep downhill grades. Use the en-
gine brake and low automatic transmis-
sion gears (D1 or D2) for engine
braking. ●
Do not operate the 4WD shift switch
(between 2WD, AUTO and 4H) with the
rear wheels spinning.
● Do not drive on dry hard surface roads
in the 4H or 4LO position. Driving on dry
hard surfaces in 4H or 4LO may cause
unnecessary noise and tire wear.
INFINITI recommends driving in the
2WD or AUTO position under these
conditions.
● The 4WD transfer case may not be
shifted between 4H and 4LO at low am-
bient temperatures and the transfer
4LO position indicator light may blink
even when the 4WD shift switch is
shifted. After driving for a while you can
change the 4WD transfer case between
4H and 4LO.
When driving on rough roads, ● Set the 4WD shift switch to AUTO, 4H or
4LO.
● Drive carefully according to the road surface
conditions.
