[ Edit: 2012/ 1/ 17 Model: V36-D ]and avoid driving when tired. Never drive
when under the influence of alcohol or
drugs (including prescription or over-the-
counter drugs which may cause drowsi-
ness). Always wear your seat belt as
outlined in the “ Seat belts ” (P.1-14) of this
manual, and also instruct your passengers
to do so.
Seat belts help reduce the risk of injury in
collisions and rollovers. In a rollover crash,
an unbelted or improperly belted person is
significantly more likely to be injured or
killed than a person properly wearing a
seat belt.
OFF-ROAD RECOVERY GUID-55350CDC-B327-47DB-A929-95DDE2B6F88F
If the right side or left side wheels may
unintentionally leave the road surface.
Maintain control of the vehicle by following
the procedure below. Please note that this
procedure is only a general guide. The
vehicle must be driven as appropriate
based on the conditions of the vehicle,
road and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering
wheel with both hands and try to hold a
straight course. 4. When appropriate, slowly release the
accelerator pedal to gradually slow the
vehicle.
5. If there is nothing in the way, steer the
vehicle to follow the road while the
vehicle speed is reduced. Do not
attempt to drive the vehicle back onto
the road surface until vehicle speed is
reduced.
6. When it is safe to do so, gradually turn
the steering wheel until both tires
return to the road surface. When all
tires are on the road surface, steer the
vehicle to stay in the appropriate
driving lane. .
If you decide that it is not safe to
return the vehicle to the road surface
based on vehicle, road or traffic
conditions, gradually slow the vehi-
cle to a stop in a safe place off the
road. RAPID AIR PRESSURE LOSS GUID-F6877DBB-5B63-45D0-9CA2-EC1F801DC510
Rapid air pressure loss or a “ blow-out ” can
occur if the tire is punctured or is damaged
due to hitting a curb or pothole. Rapid air
pressure loss can also be caused by
driving on under-inflated tires.
Rapid air pressure loss can affect the
handling and stability of the vehicle,
especially at highway speeds.
Help prevent rapid air pressure loss by
maintaining the correct air pressure and
visually inspect the tires for wear and
damage. See “ Wheels and tires ” (P.8-33) of
this manual.
If a tire rapidly loses air pressure or
“ blows-out ” while driving maintain control
of the vehicle by following the procedure
below. Please note that this procedure is
only a general guide. The vehicle must be
driven as appropriate based on the condi-
tions of the vehicle, road and traffic.
WARNING The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air pressure.
Losing control of the vehicle may cause a

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 (329,1)
[ Edit: 2012/ 1/ 17 Model: V36-D ]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 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 unex-
pected vehicle movement which could
result in serious vehicle damage or
personal injury.
. When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively. GUID-A0F35CA1-ADE1-478F-ABDB-FB4DD4BF0426
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 (for automatic
transmission model) or the shift lever to
the N (Neutral) position (for manual trans-
mission model).
INTELLIGENT KEY SYSTEM GUID-5C22F5F0-8E63-49DB-8E3C-09EA9AB0E315
The Intelligent Key system can operate the
ignition switch without it being taken out
from your pocket or purse. The operating
environment and/or conditions may affect
the Intelligent Key system operation.
Some indicators and warnings for opera-
tion are displayed on the dot matrix liquid
crystal display between the speedometer
and tachometer. (See “ Dot matrix liquid crystal display ” (P.2-20).)
CAUTION . Be sure to carry the Intelligent Key with
you when operating the vehicle.
. Never leave the Intelligent Key inside the
vehicle when you leave the vehicle.
. If the vehicle battery is discharged, the
ignition switch cannot be switched from
the LOCK position. Charge the battery as
soon as possible. (See “ Jump starting ”
(P.6-8).)

Use this position when climbing steep hills
slowly or driving slowly through deep
snow, or for maximum engine braking on
steep downhill grades.
. Remember not to drive at high speeds
for extended periods of time in lower
than 7th gear. This reduces fuel econ-
omy.
. Moving the selector lever rapidly to the
same side twice will shift the ranges in
succession.
. In the manual shift mode, the transmis-
sion may not shift to the selected gear.
This helps maintain driving perfor-
mance and reduces the chance of
vehicle damage or loss of control.
When this situation occurs, the Auto-
matic Transmission (AT) position indi-
cator light (on the dot matrix liquid
crystal display) will blink and the
chime will sound.
. In the manual shift mode, the transmis-
sion automatically shifts down to 1st
gear before the vehicle comes to a stop. When accelerating again, it is
necessary to shift up to the desired
range.
Accelerator downshift — In D (Drive)
position — GUID-E91E596E-66F0-4B37-B592-BD241B7B4C14
For passing or hill climbing, fully depress
the accelerator pedal to the floor. This
shifts the transmission down into the lower
gear, depending on the vehicle speed.
Fail-safe GUID-852B8196-DDA1-4E5B-AA0C-3EDBD2A757EE
When the fail-safe operation occurs, note
that the transmission will be locked in any
of the forward gears according to the
condition.
If the vehicle is driven under extreme
conditions, such as excessive wheel spin-
ning and subsequent hard braking, the
fail-safe system may be activated. This will
occur even if all electrical circuits are
functioning properly. In this case, push
the ignition switch to the OFF position and
wait for 3 seconds. Then push the ignition
switch back to the ON position. The vehicle
should return to its normal operating
condition. If it does not return to its
normal operating condition, have an
INFINITI retailer check the transmission
and repair if necessary. SSD0598

CAUTIONDuring the first 1,200 miles (2,000 km),
follow these recommendations to obtain
maximum engine performance and ensure
the future reliability and economy of your
new vehicle.
Failure to follow these recommendations
may result in shortened engine life and
reduced engine performance.
. Avoid driving for long periods at con-
stant speed, either fast or slow. Do not
run the engine over 4,000 rpm.
. Do not accelerate at full throttle in any
gear.
. Avoid quick starts.
. Avoid hard braking as much as possi-
ble. GUID-DE80132E-86B2-4CC9-A3AE-29D2B23A6BF7
. Accelerate slowly and smoothly. Main-
tain cruising speeds with a constant
accelerator position.
. Drive at moderate speeds on the high-
way.
. Avoid unnecessary stopping and brak-
ing. Keep a safe distance behind other
vehicles.
. Select a gear range suitable to road
conditions.
. Avoid unnecessary prolonged engine
idling.
. Keep your engine tuned up.
. Follow the recommended periodic main-
tenance schedule.
. Keep the tires inflated at the correct
pressure. Improper tire pressure will
increase wear and waste fuel.
. Make sure the front wheels are properly
aligned. Improper alignment will cause
premature tire wear and lower fuel
economy.
. Climate control operation lowers fuel
economy. Use the air conditioner only
when necessary.
. When cruising at highway speeds, it is
more economical to use the air condi-
tioner and leave the windows closed to
reduce drag. GUID-EF560502-444A-4256-8716-FF357EB68302

[ 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.

WARNING. Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite and
cause a fire.
. Never leave the engine running while the
vehicle is unattended.
. Do not leave children unattended inside
the vehicle. They could unknowingly
activate switches or controls. Unat-
tended children could become involved
in serious accidents. . Safe parking procedures require that
both the parking brake be applied and
the transmission placed into P (Park) for
Automatic Transmission (AT) model or in
an appropriate gear for Manual Trans-
mission (MT) model. Failure to do so
could cause the vehicle to move un-
expectedly or roll away and result in an
accident.
. Make sure the automatic transmission
selector lever has been pushed as far
forward as it can go and cannot be
moved without depressing the foot
brake pedal. 1. Firmly apply the parking brake.
2. Automatic transmission models:
Move the selector lever to the P (Park)
position.
Manual transmission models:
Place the shift lever in the R (Reverse)
gear. When parking on an uphill grade,
place the shift lever in the 1st gear.
3. To help prevent the vehicle from rolling
into the street when parked on a
sloping drive way, it is a good practice
to turn the wheels as illustrated. .
HEADED DOWNHILL WITH CURB:
* 1
Turn the wheels into the curb and
move the vehicle forward until the
curb side wheel gently touches the
curb. .
HEADED UPHILL WITH CURB:
* 2
Turn the wheels away from the curb
and move the vehicle back until the
curb side wheel gently touches the
curb. .
HEADED UPHILL OR DOWNHILL, NO
CURB:
* 3
Turn the wheels toward the side of
the road so the vehicle will move
away from the center of the road if it
moves.

BRAKING PRECAUTIONS GUID-69469B45-E0A5-4BC3-B99F-C3213CC27874
The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
Vacuum assisted brakes GUID-95686AE6-7A34-4D3E-9305-085085C76F84
The brake booster aids braking by using
engine vacuum. If the engine stops, you
can stop the vehicle by depressing the
brake pedal. However, greater foot pres-
sure on the brake pedal will be required to
stop the vehicle and the stopping distance
will be longer.
When the brake pedal is depressed slowly
and firmly, you may hear a clicking noise
and feel a slight pulsation. This is normal
and indicates that the Brake Assist System
is operating.
Wet brakes GUID-B2433212-C5E2-4B61-9394-8ED34BB6A681
When the vehicle is washed or driven
through water, the brakes may get wet.
As a result, your braking distance will be
longer and the vehicle may pull to one side
during braking.
To dry brakes, drive the vehicle at a safe
speed while lightly tapping the brake pedal
to heat-up the brakes. Do this until the
brakes return to normal. Avoid driving the vehicle at high speeds until the brakes
function correctly.
PARKING BRAKE BREAK-IN GUID-B441C7AD-F0BB-453E-A531-8E92178C3484
Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or drums/rotors are replaced,
in order to assure the best braking
performance.
This procedure is described in the vehicle
service manual and can be performed by
an INFINITI retailer.
Using the brakes GUID-EB3F3C9C-0F2F-47F8-8239-331D9D489654
Avoid resting your foot on the brake pedal
while driving. This will cause overheating
of the brakes, wearing out the brake and
pads faster and reduce gas mileage.
To help save the brakes and to prevent the
brakes from overheating, reduce speed
and downshift to a lower gear before going
down a slope or long grade. Overheated
brakes may reduce braking performance
and could result in loss of vehicle control. WARNING . While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
. If the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.

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.
