SYSTEM MAINTENANCE
The sensoris located behind the lower
grille of the front bumper.
To keep the system operating properly, be
sure to observe the following:
. Always keep the sensor area of the front
bumper clean.
. Do not strike or damage the areas around
the sensor.
. Do not cover or attach stickers or similar
objects on the front bumper near the
sensor area. This could cause failure or
malfunction.
. Do not attach metallic objects near the
sensor area (brush guard, etc.). This

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.

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 a stuck 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.

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.2-26).)
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 “27. Chassis con-
trol warning” (P.2-22).)
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
.The sonar system is a convenience
but it is not a substitute for proper
parking. Always look around and
check that it is safe to do so before
parking. Always move slowly.
. Read and understand the limitations
of the sonar system as contained in
this section. Inclement weather may
affect the function of the sonar
system; this may include reduced
performance or a false activation. .
This system is not designed to pre-
vent contact with small or moving
objects.
. The system is designed as an aid to
the driver in detecting large station-
ary objects to help avoid damaging
the vehicle. The system will not
detect small objects below the bum-
per, and may not detect objects that
are too close to the bumper or on the
ground.
. If your vehicle sustains damage to the
bumper fascia, leaving it misaligned
or bent, the sensing zone may be
altered causing inaccurate measure- ment of obstacles or false alarms.
CAUTION
Keep the interior of the vehicle as quiet
as possible to hear the tone clearly.
The sonar system sounds a tone to warn the
driver of obstacles near the bumper. When
the [Auto Show Sonar Image] key is turned
on in the [Parking Sonar] settings, the sonar
indicator will also appear on the upper
display. (See “Sonar indicator” (P.5-135).)
The system detects front obstacles when the
shift lever is in the D (Drive) position or N
(Neutral) position. The system detects both
front and rear obstacles when the shift lever
is in the R (Reverse) position.
The system may not detect objects at speeds
above 6 MPH (10 km/h) and may not detect
certain angular or moving objects.
The sonar system detects obstacles up to
3.9 ft (1.2 m) from the bumper with a
decreased coverage area at the outer cor-
ners of the bumper. Refer to the illustration
for approximate zone coverage areas. As
you move closer to the obstacle, the rate of
the tone increases. When the obstacle is less
than 11.8 in (30 cm) away, the tone will

sound continuously.
Keep the corner/center sonar (located on
the bumper fascia) free from snow, ice and
large accumulations of dirt (do not clean the
sonar with sharp objects). If the sonar is
covered, it will affect the accuracy of the
sonar system.
The sensitivity level of the corner/center
sonar can be adjusted (higher or lower) on
the lower display.
The intermittent tone will stop in 3 seconds
when an obstacle is detected by only the
corner sensor and the distance does not
change.

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-
10) and “Tire Pressure Monitoring System
(TPMS)” (P.5-5).
WARNING
.
Radio waves could adversely affect
electric medical equipment. Those who 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).
. 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
