If the “AWD Error” warningappears, there
may be a malfunction in the Intelligent AWD
system. Reduce vehicle speed and have the
system checked as soon as possible. It is
recommended you visit an INFINITI retailer
for this service.
The “AWD High Temp.” (high temperature)
warning
may appear while trying to free astuck vehicle due to increased oil tempera-
ture. The driving mode may change to Two-
Wheel Drive (2WD). If this warning is
displayed, stop the vehicle with the engine
idling, as soon as it is safe to do so. Then if
the warning turns off, you can continue
driving.
The “Tire Size Incorrect” warning
may
appear if there is a large difference between
the diameters of front and rear wheels. Pull
off the road in a safe area, with the engine
idling. Check that all tire sizes are the same,
that the tire pressure is correct and that the
tires are not excessively worn.
If any warning message continues to be
displayed, have your vehicle checked as soon
as possible. It is recommended you visit an
INFINITI retailer for this service.
WARNING
.For AWD equipped vehicles, do not
attempt 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
vehicle movement which could result
in serious vehicle damage or personal
injury.
INTELLIGENT ALL-WHEEL
DRIVE (AWD) (if so equipped)

.Do not attempt to test an AWD
equipped vehicle on a 2-wheel dy-
namometer (such as the dynam-
ometers used by some states for
emissions testing) or similar equip-
ment even if the other two wheels are
raised off the ground. Make sure that
you inform the test facility personnel
that your vehicle is equipped with
AWD before it is placed on a dynam-
ometer. Using the wrong test equip-
ment may result in drivetrain damage
or unexpected vehicle movement
which could result in serious vehicle
damage or personal injury.
CAUTION
.Do not operate the engine on a free
roller when any of the wheels are
raised.
.If the “AWD Error” warning appears
while driving there may be a mal-
function in the AWD system. Reduce
the vehicle speed and have your
vehicle checked as soon as possible.
It is recommended you visit an
INFINITI retailer for this service.

position.ELECTRIC POWER STEERING
TYPE
WARNING
.If the engine is not running or is
turned off while driving, the power
assist for the steering will not work.
Steering will be harder to operate.
.When the power steering warning
light illuminates with the engine run-
ning, the power assist for the steer-
ing will cease operation. You will still
have control of the vehicle but the
steering will be harder to operate.
The electric power steering is designed to
provide power assist while driving to oper-
ate the steering wheel with light force.
When the steering wheel is operated re-
peatedly or continuously while parking or
driving at a very low speed, the power assist
for the steering wheel will be reduced. This is
to prevent overheating of the electric power
steering and protect it from getting da-
maged. While the power assist is reduced,
steering wheel operation will become heavy.
When the temperature of the electric power
steering goes down, the power assist level
will return to normal. Avoid repeating suchsteering wheel operations that could cause
the electric power steering to overheat.
You may hear a sound when the steering
wheel is operated quickly. However, this is
not a malfunction.
If the power steering warning light illumi-
nates while the engine is running, it may
indicate the electric power steering is not
functioning properly and may need servicing.
It is recommended you have the electric
power steering checked by an INFINITI
retailer. (See “Power steering warning light”
(P.2-18).)
When the power steering warning light
illuminates with the engine running, the
power assist for the steering will cease
operation. You will still have control of the
vehicle. However, greater steering effort is
needed, especially in sharp turns and at low
speeds.
DIRECT ADAPTIVE STEERING
TYPE
WARNING
.When the power steering warning
light illuminates with the engine run-
ning, the power assist for the steer-
ing will cease operation. You will still

have control of the vehicle, but the
steering will be harder to operate.
.If wheels or tires other than the
INFINITI recommended ones are
used, Direct Adaptive Steering may
not operate properly and the power
steering warning light may illumi-
nate.
.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,
Direct Adaptive Steering may not
operate properly and the power
steering warning light may illumi-
nate.
.Do not modify the vehicle’s steering.
If steering parts are not INFINITI
recommended for your vehicle or are
extremely deteriorated, Direct Adap-
tive Steering may not operate prop-
erly and the power steering warning
light may illuminate.
.If the VDC warning light illuminates,
the power steering warning light may
also illuminate at the same time. Stop
the vehicle in a safe location, turn the
engine off and restart the engine. If
the power steering warning lightcontinues to illuminate, have the
system checked. It is recommended
you visit an INFINITI retailer for this
service. For the VDC system, see
“Vehicle Dynamic Control (VDC) sys-
tem” (P.5-132).
CAUTION
.Do not place the ignition switch is in
the ON position while the steering
wheel or a tire is removed.
.Do not turn the steering wheel as
much as possible while the ignition
switch is in any position other than
the ON position.
.Installing an accessory on the steer-
ing wheel, or changing the steering
wheel, may reduce the steering per-
formance.
Direct Adaptive Steering is designed to
control the steering force and steering angle
according to the vehicle speed and amount
of turning of the steering wheel.
The steering characteristic can be selected
using the INFINITI Drive Mode Selector. See
“INFINITI Drive Mode Selector” (P.5-21).
If the VDC system is turned off, the settingof steering becomes standard mode.
If the power steering warning light illumi-
nates while the engine is running, it may
indicate that Direct Adaptive Steering is not
functioning properly and may need servicing.
It is recommended you have the system
checked by an INFINITI retailer. (See “Power
steering warning light” (P.2-18).)
When the power steering warning light
illuminates with the engine running, the
power assist for the steering will cease
operation. You will still have control of the
vehicle. However, greater steering effort will
be needed, especially in sharp turns and at
low speeds.
If Direct Adaptive Steering is malfunction-
ing, the steering wheel may turn slightly even
when driving on a straight road.
Under the following conditions, the steering
wheel may turn slightly even when driving on
a straight road. This is due to a protection
mechanism for Direct Adaptive Steering. The
steering wheel will return to the normal
position after the protection mechanism is
deactivated.
Condition A
.When the engine is stalled or likely to be
stalled
.When the steering wheel is held in the full
lock position or when the front tire
touches an obstruction.

faces will be longer than on normal
surfaces even with ABS. Stopping
distances may also be longer on
rough, gravel or snow covered roads,
or if you are using tire chains. Always
maintain a safe distance from the
vehicle in front of you. Ultimately,
the driver is responsible for safety.
.Tire type and condition may also
affect braking effectiveness.
— When replacing tires, install the
specified size of tires on all four
wheels.
— When installing a spare tire, make
sure that it is the proper size and
type as specified on the Tire and
Loading Information label. See
“Tire and loading information la-
bel” (P.10-13) of this manual.
— For detailed information, see
“Wheels and tires” (P.8-25) of
this manual.
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 eachwheel 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
pressure, 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 dis-
tances.
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 mal-function, it switches the ABS off and
illuminates the ABS warning light on the
instrument panel. The brake system then
operates normally, but without anti-lock
assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the
vehicle checked. It is recommended you visit
an INFINITI retailer for this service.
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h).
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. 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 pulsation may indi-
cate that road conditions are hazardous and
extra care is required while driving.

SONAR INDICATOR
When the corner of the vehicle moves closer
to an object, the corner sensor indicator
appears on the upper display.
When the center of the vehicle moves close
to an object, the center sensor indicator
appears on the upper display.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock
becomes frozen, heat the key before insert-
ing it into the key hole or use the Intelligent
Key system.
ANTIFREEZE
In the winter when it is anticipated that the
outside temperature will drop below 32°F
(0°C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system” (P.8-3) or
“Intercooler cooling system” (P.8-5).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the bat-
tery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly. For
additional information, see “Battery” (P.8-
11).
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For details, see “Engine cooling
system” (P.8-3).
TIRE EQUIPMENT
SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your
vehicle on snowy or icy roads, INFINITI
recommends the use of MUD & SNOW or
ALL SEASON tires on all four wheels. It is
recommended you consult an INFINITI re-
tailer for the tire type, size, speed rating and
availability information.
For additional traction on icy roads, studded
tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing studded tires.
Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may be
poorer than that of non-studded snow tires.
Tire chains may be used. For details, see
“Tire chains” (P.8-34) of this manual.
Intelligent All-Wheel Drive (AWD)
models
If you install snow tires, they must also be
the same size, brand, construction and tread
pattern on all four wheels.
COLD WEATHER DRIVING

To shut off the engine in an emergency
situation while driving, perform the follow-
ing procedure:
.Rapidly push the push-button ignition
switch 3 consecutive times in less than
1.5 seconds, or
.Push and hold the push-button ignition
switch for more than 2 seconds.If you have a flat tire, follow the instructions
in this section.
For models with run-flat tires, you can
continue driving to a safe location even if
they are punctured. (See “Run-flat tires”
(P.6-4) and “Run-flat tires” (P.8-32).)
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except the
spare. When the low tire pressure warning
light is lit and the “Tire Pressure Low - Add
Air” warning appears in the vehicle informa-
tion display, one or more of your tires is
significantly under-inflated. If the vehicle is
being driven with low tire pressure, the
TPMS will activate and warn you of it by
the low tire pressure warning light. This
system will activate only when the vehicle is
driven at speeds above 16 MPH (25 km/h).
For more details, see “Warning lights, in-
dicator lights and audible reminders” (P.2-
12) and “Tire Pressure Monitoring System
(TPMS)” (P.5-5).
WARNING
.Radio waves could adversely affect
electric medical equipment. Thosewho use a pacemaker should contact
the electric medical equipment man-
ufacturer for the possible influences
before use.
.If the low tire pressure warning light
illuminates while driving, avoid sud-
den 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
increase the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and
could result 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 to turn the low tire
pressure warning light OFF. If the
light still illuminates while driving
after adjusting the tire pressure, a
tire may be flat. If you have a flat tire,
replace it with a spare tire (if so
equipped) or repair it with the emer-
gency tire puncture repair kit (if so
equipped) as soon as possible. If no
tire is flat and all tires are properly
inflated, it is recommended you con-
sult an INFINITI retailer.
