[ Edit: 2012/ 1/ 17 Model: V36-D ]2-16 Instruments and controlsWARNING. 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 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.
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 the 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.

Owner ’ s Manual. DRINKING ALCOHOL/DRUGS AND
DRIVING GUID-9FACE374-80C0-473A-AF0E-37D9C4BE0B25
WARNING Never drive under the influence of alcohol or
drugs. Alcohol in the bloodstream reduces
coordination, delays reaction time and im-
pairs 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. Although 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, prescription, and illegal drugs). Don ’ t drive if your ability to operate your
vehicle is impaired by alcohol, drugs, or
some other physical condition.
ALL-WHEEL DRIVE (AWD) DRIVING
SAFETY PRECAUTIONS GUID-A083649A-0774-46ED-A3DF-AB198E309722
WARNING . Do not drive beyond the performance
capability of the tires, even with AWD
engaged. Accelerating quickly, sharp
steering maneuvers or sudden braking
may cause loss of control.
. 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.
. This vehicle is not designed for offroad
(rough road) use. Do not drive on sandy
or muddy roads that tires may get stuck
in.
. For AWD equipped vehicles, do not
attempt to raise two wheels off the
ground and shift the transmission to
any D (Drive) or R (Reverse) position with
the engine running. Doing so may result

Black plate (366,1)
[ Edit: 2012/ 1/ 17 Model: V36-D ]5-46 Starting and drivingIf any malfunction occurs in the AWD
system while the engine is running, the
warning light will come on.
The warning light may blink rapidly (about
twice per second) while trying to free a
stuck vehicle due to high power train oil
temperature. The driving mode may change
to two-wheel drive. If the warning light
blinks rapidly during operation, stop the
vehicle with the engine idling in a safe
place immediately. Then if the light goes
off after a while, you can continue driving.
A large difference between the diameters
of front and rear wheels will make the
warning light blink slowly (about once per
two seconds). Pull off the road in a safe
area, and idle the engine. Check that all
tire sizes are the same, tire pressure is
correct and tires are not worn.
If the warning light is blinking after the
above operation, have your vehicle
checked by an INFINITI retailer as soon as
possible.
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.
. Do not attempt to test an AWD 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 that
you inform the 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 unex-
pected 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 warning light comes on while
driving there may be a malfunction in the AWD system. Reduce the vehicle
speed and have your vehicle checked by
an INFINITI retailer as soon as possible.
. If the warning light remains on after the
above operation, have your vehicle
checked by an INFINITI retailer as soon
as possible.
. The power train may be damaged if you
continue driving with the warning light
blinking.

[ Edit: 2012/ 1/ 17 Model: V36-D ]5-54 Starting and drivingHow to handle the sensor GUID-89745A21-1C60-412A-886B-4129187B34E7
The sensor for the Preview Function is
common with Intelligent Cruise Control and
is located below the front bumper.
To keep the Preview Function operating
properly, be sure to observe the following:
. Always keep the sensor clean. Wipe
with a soft cloth carefully so as not to
damage the sensor.
. Do not strike or damage the areas
around the sensor. Do not touch or
remove the screw located on the
sensor. Doing so could cause failure
or malfunction. If the sensor is da-
maged due to an accident, contact an
INFINITI retailer.
. Do not attach a sticker (including
transparent material) or install an
accessory near the sensor. This could
cause failure or malfunction. ANTI-LOCK BRAKING SYSTEM (ABS) GUID-FD13D872-FF09-485D-9889-39301203B8FE
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 “ Tire and loading information label ” (P.9-
14) of this manual.
— For detailed information, see
“ Wheels and tires ” (P.8-33) 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 GUID-CD765EBE-4FB0-423D-988E-36D396A7E6A5
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.

FREEING A FROZEN DOOR LOCK GUID-5F57F3E0-2969-4980-A1A0-BD5D647B2C54
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 GUID-F8D7961D-C579-4F53-826C-B5C0F179A8A4
In the winter when it is anticipated that the
outside temperature will drop below 32 8 F
(0 8 C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “ Engine cooling system ” (P.8-9).
BATTERY GUID-7370DBB5-3733-4F67-B170-202B0ECEAFD5
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 GUID-1E2017DE-B388-4F4A-AC44-3F639AB39240
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 GUID-CB13ADAD-1389-4CA9-89D4-C970D4152E81
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 GUID-7A027A3E-CFDC-48CE-8A84-86EFBDFF0BCB
If you install snow tires, they must also be
the same size, brand, construction and
tread pattern on all four wheels. SPECIAL WINTER EQUIPMENT GUID-6AEDC1F1-78E0-49EE-A495-05AD7B0A46B7
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 GUID-0864712C-2A8E-4B2A-96E7-B1801A0D999A
WARNING . Wet ice (32 8 F, 0 8 C 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 evenCOLD WEATHER DRIVING
