If any malfunction occurs in the Intelligent
All-Wheel Drive (AWD) system while the
engine is running, warning messages appear
in the vehicle information display.
JVS0228M
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.

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.

be especially careful when driving and
cornering on slippery surfaces and
always drive carefully.
.The brake force distribution system
may not be effective depending on
the driving condition. Always drive
carefully and attentively.
.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
snow covered road.This system senses driving based on the
driver’s steering and acceleration/braking
patterns, and controls brake pressure at
individual wheels to help smooth vehicle
response.
When the SPORT mode is selected by the
INFINITI Drive Mode Selector, the amount
of brake control provided by the active trace
control is reduced.
When the PERSONAL mode is selected, the
active trace control can be set to ON
(enabled) or OFF (disabled). See “INFINITI
Drive Mode Selector” (P.5-21).
When the VDC OFF switch is used to turn
off the VDC system, the active trace control
is also turned off.

When the active trace control is operated
and the “Chassis Control” mode is selected in
the trip computer, the active trace control
graphics are shown in the vehicle informa-
tion display. (See “Trip computer” (P.2-29).)
If the chassis control warning message
appears in the vehicle information display,
it may indicate that the active trace control
is not functioning properly. It is recom-
mended you have the system checked by
an INFINITI retailer. (See “26. Chassis con-
trol warning” (P.2-25).)
WARNING
The active trace control may not be
effective depending on the driving con-
dition. Always drive carefully and atten-
tively.
When the active trace control is operating,
you may feel a pulsation in the brake pedal
and hear a noise. This is normal and indicates
that the active trace control is operating
properly. You may also feel deceleration
when the active trace control is operating.
However, this is not a malfunction.Even if the active trace control is set to OFF,
some functions will remain on to assist the
driver (for example, avoidance scenes).

WARNING
.Never rely solely on the hill start
assist system to prevent the vehicle
from moving backward on a hill.
Always drive carefully and atten-
tively. Depress the brake pedal when
the vehicle is stopped on a steep hill.
Be especially careful when stopped
on a hill on frozen or muddy roads.
Failure to prevent the vehicle from
rolling backwards may result in a loss
of control of the vehicle and possible
serious injury or death.
.The hill start assist system is not
designed to hold the vehicle at a
standstill on a hill. Depress the brake
pedal when the vehicle is stopped on
a steep hill. Failure to do so may
cause the vehicle to roll backwards
and may result in a collision or serious
personal injury.
.The hill start assist system may not
prevent the vehicle from rolling back-
wards on a hill under all load or road
conditions. Always be prepared to
depress the brake pedal to prevent
the vehicle from rolling backwards.
Failure to do so may result in a
collision or serious personal injury.The hill start assist system automatically
keeps the brakes applied to help prevent the
vehicle from rolling backwards in the time it
takes the driver to release the brake pedal
and apply the accelerator when the vehicle is
stopped on a hill.
The hill start assist system will operate
automatically under the following condi-
tions:
.The transmission is shifted to a forward
or reverse gear.
.The vehicle is stopped completely on a hill
by applying the brake.
The maximum holding time is 2 seconds.
After 2 seconds the vehicle will begin to roll
back and the hill start assist system will stop
operating completely.
The hill start assist system will not operate
when the transmission is shifted to the N
(Neutral) or P (Park) position or on a flat and
level road.
The chassis control is an electric control
module that includes the following func-
tions:
.Log-in function (See “Log-in function”
(P.3-15).)
.INFINITI Drive Mode Selector (See
“INFINITI Drive Mode Selector” (P.5-
21).)
.Active Lane Control (if so equipped) (See
“Active Lane Control” (P.5-25).)

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.

.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.
In case of emergency6-3
EMERGENCY ENGINE SHUT OFF FLAT TIRE

6-4In case of emergency
.Since the spare tire is not equipped
with the TPMS, when a spare tire is
mounted or a wheel is replaced, 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. Have
your tires replaced and/or TPMS
system reset as soon as possible. It
is recommended you visit an INFINITI
retailer for these services.
.Replacing tires with those not origin-
ally specified by INFINITI could affect
the proper operation of the TPMS.
.Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pres-
sure sensors.
.INFINITI recommends using only
Genuine NISSAN Emergency Tire
Sealant provided with your vehicle.
Other tire sealants may damage the
valve stem seal which can cause the
tire to lose air pressure. It is recom-
mended you visit an INFINITI retailer
as soon as possible after using tire
repair sealant (for models equipped
with the emergency tire puncture
repair kit).RUN-FLAT TIRES
Run-flat tires are those tires that can be
used temporarily if they are punctured. See
“Run-flat tires” (P.8-32).
Also, refer to “Important Tire Safety Infor-
mation” (US) or “Tire Safety Information”
(Canada) in the INFINITI Warranty Informa-
tion Booklet.
WARNING
.Although you can continue driving
with a punctured run-flat tire, re-
member that vehicle handling stabi-
lity is reduced, which could lead to an
accident and personal injury. Also,
driving a long distance at high speeds
may damage the tires.
.Do not drive at speeds above 50
MPH (80 km/h) and do not drive
more than approximately 93 miles
(150 km) with a punctured run-flat
tire. The actual distance the vehicle
can be driven on a flat tire depends on
outside temperature, vehicle load,
road conditions and other factors.
.Drive safely at reduced speeds. Avoid
hard cornering or braking, which may
cause you to lose control of the
vehicle..If you detect any unusual sounds or
vibrations while driving with a punc-
tured run-flat tire, pull off the road
to a safe location and stop the vehicle
as soon as possible. The tire may be
seriously damaged and need to be
replaced.
CAUTION
.Never install tire chains on a punctu-
red run-flat tire, as this could damage
your vehicle.
.Avoid driving over any projection or
pothole, as the clearance between
the vehicle and the ground is smaller
than normal.
.Do not enter an automated car wash
with a punctured run-flat tire.
.It is recommended you have the
punctured tire inspected by an
INFINITI retailer or other authorized
repair shop. Replace the tire as soon
as possible if the tire is seriously
damaged.
If you have a flat tire and have to stop the
vehicle, follow the instructions below.

1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the
parking brake. Move the shift lever to the
P (Park) position.
4. Turn off the engine.
5. Raise the hood to warn other traffic, and
to signal professional road assistance
personnel that you need assistance.
6. Have all passengers get out of the
vehicle and stand in a safe place, away
from traffic and clear of the vehicle.
For the tire removing procedure, see “Jack-
ing up the vehicle and replacing tires” (P.8-
38).
REPAIRING A FLAT TIRE (for
models with emergency tire punc-
ture repair kit)
WARNING
.After using Emergency Tire Sealant
to repair a minor tire puncture, do not
drive the vehicle at speeds faster
than 50 MPH (80 km/h).
.Immediately after using the Emer-
gency Tire Sealant to repair a minortire puncture, take your vehicle to
inspect, and repair or replace the tire.
It is recommended you visit an
INFINITI retailer for this service. The
Emergency Tire Sealant cannot per-
manently seal a punctured tire. Con-
tinuing operation of the vehicle
without a permanent tire repair can
lead to a crash.
.INFINITI recommends using only
Genuine NISSAN Emergency Tire
Sealant provided with your vehicle.
Other tire sealants may damage the
valve stem seal which can cause the
tire to lose air pressure. It is recom-
mended you visit an INFINITI retailer
as soon as possible after using tire
repair sealant.
This vehicle does not have a spare tire. The
emergency tire puncture repair kit (Emer-
gency Tire Sealant) is supplied with the
vehicle instead of a spare tire. It can be used
to temporarily repair minor tire punctures.
If you have a flat tire, follow the instructions
below.
CAUTION
.To avoid the emergency tire puncture
repair kit being damaged during sto-
rage or use:
— Only use the emergency tire
puncture repair kit on your vehi-
cle. Do not use it on other vehicles.
— Only use the kit to inflate the
tires of your vehicle and to check
the vehicle’s tire pressure.
— Only plug the compressor into a
12V DC car power point.
— Keep the kit free of water and
dirt.
— Do not disassemble or modify the
kit.
— Do not drop the kit or allow hard
impacts to the kit.
.Do not use the emergency tire punc-
ture repair kit under the following
conditions. It is recommended you
visit an INFINITI retailer or profes-
sional road assistance.
— when the sealant has passed its
expiration date (shown on the
