information in the display, the LOW PRES-
SURE information will be displayed. The
tire pressure for each tire will also be
displayed.
When the low tire pressure warning light
illuminates, you should stop and adjust
the tire pressure to the recommended
COLD tire pressure shown on the Tire and
Loading Information label. The low tire
pressure warning light does not automati-
cally turn off when the tire pressure is
adjusted. After the tire is 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.
The CHECK TIRE PRESSURE warning is
active as long as the low tire pressure
warning light remains illuminated.
For additional information, see“Tire Pres-
sure Monitoring System (TPMS)” (P.5-4)
and “Tire Pressure Monitoring System
(TPMS)” (P.6-2). For the CHECK TIRE PRES-
SURE warning, see “Dot matrix liquid
crystal display” (P.2-21). TPMS malfunction:
If the TPMS is not functioning properly, the
low tire pressure warning light will flash for
approximately 1 minute when the ignition
switch is pushed ON. The light will remain
on after 1 minute. Have the system
checked by an INFINITI retailer. The CHECK
TIRE PRESSURE warning does not appear if
the low tire pressure warning light illumi-
nates to indicate a TPMS malfunction.
For additional information, see “Tire Pres-
sure Monitoring System (TPMS)” (P.5-4).
WARNING
.If the light does not illuminate with the
ignition switch pushed ON, have the
vehicle checked by an INFINITI retailer as
soon as possible.
. If the light illuminates or LOW PRESSURE
information is displayed on the monitor
screen 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 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 as soon as possible.
. 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.
Contact your INFINITI retailer 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 four wheels correctly.
Master warning light
When the ignition switch is in the ON
position, the master warning light illumi-
nates if any of the following are displayed
on the dot matrix liquid crystal display:
.No key warning
. Low fuel warning
. Low washer fluid warning
. Parking brake release warning
. Door/lift gate open warning
. Loose fuel cap warning
. Check tire pressure warning
See “Dot matrix liquid crystal display” (P.2-
21).
Preview Function warning light
(orange; if so equipped)
The light comes on if there is a malfunction
in the Brake Assist (with Preview Function)
system.
If the warning light comes on, park the
vehicle in a safe place. Turn the engine off,
restart the engine, then resume driving.
If it is not possible to set the ICC system or
the Preview Function warning light re-
mains on, it may indicate that the system
is malfunctioning. Although the vehicle is
still driveable under normal conditions,
have the vehicle checked at an INFINITI
retailer.
Rear Active Steer warning light
(if so equipped)
If the light comes on while the engine is
running, it may indicate that there is a
malfunction with the Rear Active Steer
portion of the steering system. Have the
system checked by an INFINITI retailer.
For further information about the Rear
Active Steer system, see “Rear active steer
system” (P.5-85).
If a malfunction occurs in the system, the
Rear Active Steer function will cease but driving can be continued.
If the light comes on while you are driving,
contact an INFINITI retailer for repair.
Seat belt warning light and
chime
The light and chime remind you to fasten
seat belts. The light illuminates whenever
the ignition switch is pushed to the ON
position, and will remain illuminated until
the driver’s seat belt is fastened. At the
same time, the chime will sound for about
6 seconds unless the driver’s seat belt is
securely fastened.
The seat belt warning light for the front
passenger will illuminate if the seat belt is
not fastened when the front passenger’s
seat is occupied. For about 5 seconds after
the ignition switch is in the ON position,
the system does not activate the warning
light for the front passenger.
See “Seat belts” (P.1-11) for precautions
on seat belt usage.

Additional information
.The TPMS does not monitor the tire
pressure of the spare tire.
. The TPMS will activate only when the
vehicle is driven at speeds above 16
MPH (25 km/h). Also, this system may
not detect a sudden drop in tire
pressure (for example a flat tire while
driving).
. The low tire pressure warning light does
not automatically turn off when the tire
pressure is adjusted. After the tire is
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.
. The CHECK TIRE PRESSURE warning also
appears on the dot matrix liquid crystal
display when the low tire pressure
warning light is illuminated and low
tire pressure is detected. The CHECK
TIRE PRESSURE warning turns off when
the low tire pressure warning light
turns off.
The CHECK TIRE PRESSURE warning
does not appear if the low tire pressure
warning light illuminates to indicate a TPMS malfunction.
. 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 illuminate. If
the warning light illuminates in low
ambient temperature, check the tire
pressure for all four tires.
. You can also check the pressure of all
tires (except the spare tire) on the
display screen. The order of the tire
pressure figures displayed on the
screen does not correspond with the
actual order of the tire position. See
“TIRE PRESSURE information” (P.4-11).
For additional information, see “Low tire
pressure warning light” (P.2-15) and“Tire
Pressure Monitoring System (TPMS)” (P.6-
2).
WARNING
. If the low tire pressure warning light
illuminates or LOW PRESSURE informa-
tion is displayed on the monitor screen 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 increase the likelihood of tire fail-
ure. 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 as soon as
possible. (See
“Flat tire” (P.6-2) for
changing a flat tire.)
. 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.
Contact your INFINITI retailer as soon as
possible for tire replacement and/or
system resetting.

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 AWD before it is
placed on a dynamometer. Using the
wrong test equipment may result in
drivetrain damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury. (AWD
models)
. When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
. Accelerating quickly, sharp steering
maneuvers or sudden braking may cause
loss of control.
. If at all possible, avoid sharp turning
maneuvers, particularly at high speeds.
Your vehicle has a higher center of
gravity than a conventional passenger
car. The vehicle is not designed for
cornering at the same speeds as con-
ventional passenger cars. Failure to
operate this vehicle correctly could
result 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 immediately
after driving in mud or water. See “Brake
system” (P.5-78) 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 the maintenance
information in the “INFINITI Service and
Maintenance Guide”.
. Spinning the rear wheels on slippery
surfaces may cause the AWD warning
light to flash and the AWD system to
automatically switch from the AWD
mode to the 2WD mode. This could
reduce traction. Be especially careful
when towing a trailer. (AWD models)WARNING
Do not operate the push-button ignition
switch while driving the vehicle except in an
emergency. (The engine will stop when the
ignition switch is pushed 3 consecutive
times or the ignition switch is pushed and
held for more than 2 seconds.) If the engine
stops while the vehicle is being driven, this
could lead to a crash and serious injury.
Before operating the push-button ignition
switch, be sure to move the selector lever
to the P (Park) position.

ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
.The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless or
dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remember
that stopping distances on slippery
surfaces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances 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 “Tireand loading information label”
(P.9-
13) of this manual.
—For detailed information, see “Wheels and tires” (P.8-32) of this
manual.
The Anti-lock Braking System (ABS) con-
trols 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 pre-
venting each wheel 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 distances.
Self-test feature
The ABS includes electronic sensors, elec-
tric 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 pulsa-
tion in the brake pedal. This is normal and
does not indicate a malfunction. If the
computer senses a malfunction, 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 by an INFINITI retailer.

The Rear Active Steer system is an electro-
nically controlled four-wheel steering sys-
tem.
The angle of the rear wheels are adjusted
by the Rear Active Steer system, depending
on the vehicle speed and steering angle.
The rear wheels are designed to turn
momentarily in the opposite direction and
then change to the same direction as the
front wheels.
At low speeds, the rear wheels will not turn
and the system functions as a two-wheel
steering system.
If a malfunction occurs in the system, the
Rear Active Steer function will stop but the
ordinary two-wheel steering system will
operate normally. The“RAS”warning light
will illuminate. If the light illuminates while
driving, contact an INFINITI retailer for
repair.
WARNING
The Rear Active Steer system, although a
sophisticated device, cannot prevent acci-
dents resulting from careless or dangerous
driving techniques. Ultimately the responsi-
bility for safety of self and others rests in
the hands of the driver. Therefore only through attentive and careful driving meth-
ods can the Rear Active Steer system be
fully appreciated and safety assured.
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
inserting 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 328F
(08C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system” (P.8-9).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, see “Battery”
(P.8-17).
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, in-
cluding the engine block. Refill before
operating the vehicle. For details, see
“Engine cooling system” (P.8-9).

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.
Consult an INFINITI retailer 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 prohi-
bit 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.8-39) of this manual.
For all-wheel drive
If you install snow tires, they must also be
the same size, brand, construction and
tread pattern on all four wheels.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
.A scraper and stiff-bristled brush to
remove ice and snow from the windows
and wiper blades.
. A sturdy, flat board to be placed under
the jack to give it firm support.
. A shovel to dig the vehicle out of
snowdrifts.
. Extra window washer fluid to refill the
reservoir tank.
DRIVING ON SNOW OR ICE
WARNING
. Wet ice (328F, 0 8C and freezing rain),
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip”under
these conditions. Try to avoid driving on
wet ice until the road is salted or
sanded.
. Whatever the condition, drive with cau-
tion. Accelerate and slow down with
care. If accelerating or downshifting too
fast, the drive wheels will lose even more traction.
. Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
. Allow greater following distances on
slippery roads.
. Watch for slippery spots (glare ice).
These may appear on an otherwise clear
road in shaded areas. If a patch of ice is
seen ahead, brake before reaching it. Try
not to brake while on the ice, and avoid
any sudden steering maneuvers.
. Do not use the cruise control on slippery
roads.
. Snow can trap dangerous exhaust gases
under your vehicle. Keep snow clear of
the exhaust pipe and from around your
vehicle.

TOWING RECOMMENDED BY INFINITI
Two-Wheel Drive (2WD) models
INFINITI recommends that your vehicle be
towed with the driving (rear) wheels off the
ground or place the vehicle on a flat bed
truck as illustrated.
CAUTION
.Never tow automatic transmission mod-
els with the rear wheels on the ground
or four wheels on the ground (forward or
backward), as this may cause serious and expensive damage to the transmis-
sion. If it is necessary to tow the vehicle
with the front wheels raised, always use
towing dollies under the rear wheels.
. When towing rear wheel drive models
with the front wheels on the ground or
on towing dollies: Push the ignition
switch to the ACC or ON position, and
secure the steering wheel in a straight-
ahead position with a rope or similar
device.
