INTELLIGENT KEY BATTERY DIS-
CHARGE GUID-9671F916-0B52-40C4-A8B6-C2EBEE799C79
If the battery of the Intelligent Key is
almost discharged, the guide light
* B
of
the Intelligent Key port
* A
blinks and the
indicator appears on the dot matrix liquid
crystal display. (See “ Dot matrix liquid
crystal display ” (P.2-20).)
In this case, inserting the Intelligent Key
into the port
* 1
allows you to start the
engine. Make sure that the key ring side
faces backward as illustrated. Insert the
Intelligent Key in the port until it is latched
and secured. To remove the Intelligent Key from the port,
push the ignition switch to the OFF position
and pull the Intelligent Key out of the port.
NOTE:
The Intelligent Key port does not charge
the Intelligent Key battery. If you see the
low battery indicator in the dot matrix
liquid crystal display, replace the battery
as soon as possible. (See “ Intelligent Key
battery replacement ” (P.8-26).)
CAUTION . Never place anything except the Intelli-
gent Key in the Intelligent Key port.
Doing so may cause damage to the
equipment.
. Make sure the Intelligent Key is in the
correct direction when inserting it to the
Intelligent Key port. The engine may not
start if it is in the incorrect direction.
. Remove the Intelligent Key from the
Intelligent Key port after the ignition
switch is pushed to the OFF position. GUID-9AB14243-C48A-46A2-B252-8756B1BD5A3D
. Make sure the area around the vehicle
is clear.
. Check fluid levels such as engine oil,
coolant, brake fluid and window
washer fluid as frequently as possible,
or at least whenever you refuel.
. Check that all windows and lights are
clean.
. Visually inspect tires for their appear-
ance and condition. Also check tires for
proper inflation.
. Lock all doors.
. Position seat and adjust head re-
straints.
. Adjust inside and outside mirrors.
. Fasten seat belts and ask all passen-
gers to do likewise.

2 (2nd): GUID-D73A39BF-43C8-459F-9C24-47B7F579C407
Use these positions for hill climbing or
engine braking on downhill grades. M
1 (1st): GUID-D73A39BF-43C8-459F-9C24-47B7F579C407
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

If the battery charge is low or discharged,
the selector lever may not be moved from
the P (Park) position even with the brake
pedal depressed and the selector lever
button pushed.
To move the selector lever, perform the
following procedure:
1. Push the ignition switch to the OFF or
LOCK position.
2. Apply the parking brake.
3. Remove the shift lock cover

Adaptive shift control (ASC) GUID-F11A26ED-2920-48C5-B33E-4D8F7EBFD667
The adaptive shift control system automa-
tically operates when the transmission is
in the "D" (drive) and "DS" (Drive Sport)
position and selects an appropriate gear
depending on the road conditions such as
uphill, downhill or curving roads.
Control on uphill and curving roads: GUID-D73A39BF-43C8-459F-9C24-47B7F579C407
A low gear is maintained that suits the
degree of the slope or curve to allow
smooth driving with a small number of
shifts.
Control on downhill roads: GUID-D73A39BF-43C8-459F-9C24-47B7F579C407
The adaptive shift control system shifts to
a low gear that suits the degree of the slope, and uses the engine braking to
reduce the number of times that the brake
must be used.
Control on winding roads: GUID-D73A39BF-43C8-459F-9C24-47B7F579C407
A low gear is maintained on continuous
curves that involve repeated acceleration
and deceleration, so that smooth accelera-
tion is available instantly when the accel-
erator pedal is depressed.
NOTE:
. Adaptive shift control may not operate
when the transmission oil temperature
is low immediately after the start of
driving or when it is very hot.
. During some driving situations, hard
braking for example, the adaptive shift
control may automatically operate. The
transmission may automatically shift
to a lower gear for engine braking. This
increases engine speed but not vehicle
speed. Vehicle speed is controlled by
the accelerator pedal when the vehicle
is in the Adaptive shift control mode.
. When the adaptive shift control oper-
ates, the transmission sometimes
maintains a lower gear for a longer
period of time than when adaptive shift
control is not operating. Engine speed will be higher for a specific vehicle
speed while ASC system is operating
than when ASC is not operating.
MANUAL TRANSMISSION GUID-55540C91-1BB1-4931-BE6A-9E10E00B9B1A
WARNING . Do not downshift abruptly on slippery
roads. This may cause a loss of control.
. Do not over-rev the engine when shifting
to a lower gear. This may cause a loss of
control or engine damage.
CAUTION . Do not rest your foot on the clutch pedal
while driving. This may damage the
clutch.
. Fully depress the clutch pedal before
shifting to help prevent transmission
damage.
. Stop your vehicle completely before
shifting into R (Reverse).
. When the vehicle is stopped for a period
of time, for example at a stop light, shift
to N (Neutral) and release the clutch

PREVIEW FUNCTION (for Intelligent
Cruise Control system equipped
models) GUID-96A87E96-2026-4122-93F8-399D8C784D61
The ICC system with the preview function
identifies the need to apply emergency
braking by sensing the vehicle ahead in
the same lane and the distance to the
vehicle ahead and relative speed from it, it
applies the brake pre-pressure before the
driver depresses the brake pedal and helps
improve brake response by reducing pedal
free play.
For more details, see “ Brake assist ” (P.5-
52).

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.

. As there is a performance limit to the
Preview Function, never rely solely on
this system. This system does not
correct careless inattentive or absent-
minded driving, or overcome poor visi-
bility in rain, fog, or other bad weather.
Reduce vehicle speed by depressing the
brake pedal, in order to maintain a safe
distance between vehicles.
. The system may not detect the vehicle in
front of you in certain road or weather
conditions. The Preview Function may

result in increased stopping distances.
Self-test feature GUID-EC96AE96-D9F6-4F19-A5A9-937C4D6337A4
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. Normal operation GUID-36C3BA08-72B5-4E9B-96CF-93CCD7FE6655
The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h).
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic
pressure. This action is similar to pumping
the brakes very quickly. You may feel a
pulsation in the brake pedal and hear a
noise from under the hood or feel a
vibration from the actuator when it is
operating. This is normal and indicates
that the ABS is operating properly. How-
ever, the pulsation may indicate that road
conditions are hazardous and extra care is
required while driving. GUID-B2222C83-77D9-46CF-971F-591ADE2397C3
The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver
inputs and vehicle motion. Under certain
driving conditions, the VDC system helps
to perform the following functions.
. Controls brake pressure to reduce
wheel slip on one slipping drive wheel
so power is transferred to a non
slipping drive wheel on the same axle.
. Controls brake pressure and engine
output to reduce drive wheel slip based
on vehicle speed (traction control func-
tion).
. Controls brake pressure at individual
wheels and engine output to help the
driver maintain control of the vehicle in
the following conditions:
— understeer (vehicle tends to not
follow the steered path despite
increased steering input)
— oversteer (vehicle tends to spin due
to certain road or driving condi-
tions).
The VDC system can help the driver to
maintain control of the vehicle, but it
cannot prevent loss of vehicle control in
all driving situations.

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
