automatic transmission system as soon as
possible.
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

[ 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 ]. Wax your vehicle only after a thorough
washing. Follow the instructions sup-
plied with the wax.
. Do not use a wax containing any
abrasives, cutting compounds or clea-
ners that may damage the vehicle
finish.
Machine compound or aggressive polish-
ing on a base coat/clear coat paint finish
may dull the finish or leave swirl marks.
REMOVING SPOTS GUID-6A92BAAD-C79F-4B71-AC08-B8D8170F5C52
Remove tar and oil spots, industrial dust,
insects, and tree sap as quickly as possible
from the paint surface to avoid lasting
damage or staining. Special cleaning
products are available at an INFINITI
retailer or any automotive accessory
stores.
UNDERBODY GUID-235CB819-FCF9-47D3-B2C4-CF42120CA1E4
In areas where road salt is used in winter,
the underbody must be cleaned regularly.
This will prevent dirt and salt from building
up and causing the acceleration of corro-
sion on the underbody and suspension.
Before the winter period and again in the
spring, the underseal must be checked
and, if necessary, re-treated. GLASS GUID-5D4F0140-EB2A-48A1-9AE9-32E16AC93BA3
Use glass cleaner to remove smoke and
dust film from the glass surfaces. It is
normal for glass to become coated with a
film after the vehicle is parked in the hot
sun. Glass cleaner and a soft cloth will
easily remove this film.
CAUTION When cleaning the inside of the windows,
do not use sharp-edged tools, abrasive
cleaners or chlorine-based disinfectant clea-
ners. They could damage the electrical
conductors, radio antenna elements or rear
window defroster elements.
WHEELS GUID-41803024-4AB1-47D5-838F-E8FDD80A7DF3
Wash the wheels when washing the vehicle
to maintain their appearance.
. Clean the inner side of the wheels when
the wheel is changed or the underside
of the vehicle is washed.
. Inspect wheel rims regularly for dents
or corrosion. Such damage may cause
loss of pressure or poor seal at the tire
bead. . INFINITI recommends that the road
wheels be waxed to protect against
road salt in areas where it is used
during winter.
CAUTION Do not use abrasive cleaners when washing
the wheels.
Aluminum alloy wheels GUID-7407AEDF-85CD-42A8-BA1D-79993CC06EC3
Wash regularly with a sponge dampened in
a mild soap solution, especially during
winter months in areas where road salt is
used. Salt could discolor the wheels if not
removed.
CAUTION Follow the directions below to avoid stain-
ing or discoloring the wheels:
. Do not use a cleaner that uses strong
acid or alkali contents to clean the
wheels.
. Do not apply wheel cleaners to the
wheels when they are hot. The wheel
temperature should be the same as

. Rinse the wheel to completely remove
the cleaner within 15 minutes after the
cleaner is applied.
CHROME PARTS GUID-C79FFE25-59C5-419E-9237-879139BCBF04
Clean chrome parts regularly with a non-
abrasive chrome polish to maintain the
finish.
TIRE DRESSING GUID-09CB5FA2-E9A2-41B9-AA7D-C91CDF0A574B
INFINITI does not recommend the use of
tire dressings. Tire manufacturers apply a
coating to the tires to help reduce dis-
coloration of the rubber. If a tire dressing is
applied to the tires, it may react with the
coating and form a compound. This com-
pound may come off the tire while driving
and stain the vehicle paint.
If you choose to use a tire dressing, take
the following precautions:
. Use a water-based tire dressing. The
coating on the tire dissolves more
easily with an oil-based tire dressing.
. Apply a light coat of tire dressing to
help prevent it from entering the tire
tread/grooves (where it would be diffi-
cult to remove). . Wipe off excess tire dressing using a
dry towel. Make sure the tire dressing
is completely removed from the tire
tread/grooves.
. Allow the tire dressing to dry as
recommended by tire dressing manu-
facturer. GUID-034A0946-EF38-47A8-A5CE-6863A1683EE3
Occasionally remove loose dust from the
interior trim, plastic parts and seats using
a vacuum cleaner or soft bristled brush.
Wipe the vinyl and leather surfaces with a
clean, soft cloth dampened in mild soap
solution, then wipe clean with a dry soft
cloth.
Regular care and cleaning is required in
order to maintain the appearance of the
leather.
Before using any fabric protector, read the
manufacturer ’ s recommendations. Some
fabric protectors contain chemicals that
may stain or bleach the seat material.
Use a cloth dampened only with water, to
clean the meter and gauge lens.
WARNING Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can
damage the seat or occupant classification
sensors. This can also affect the operation
of the air bag system and result in serious
personal injury.CLEANING INTERIOR

Black plate (403,1)
[ Edit: 2012/ 1/ 17 Model: V36-D ]CAUTION. Never use benzine, thinner, or any
similar material.
. Small dirt particles can be abrasive and
damaging to the leather surfaces and
should be removed promptly. Do not use
saddle soap, car waxes, polishes, oils,
cleaning fluids, solvents, detergents or
ammonia-based cleaners as they may
damage the leather ’ s natural finish.
. Only use fabric protectors approved by
INFINITI.
. Do not use glass or plastic cleaner on
meter or gauge lens covers. It may
damage the lens cover.
AIR FRESHENERS GUID-C6A06011-FC8F-4E60-988D-F01757F64AC4
Most air fresheners use a solvent that
could affect the vehicle interior. If you use
an air freshener, take the following pre-
cautions:
. Hanging-type air fresheners can cause
permanent discoloration when they
contact vehicle interior surfaces. Place
the air freshener in a location that
allows it to hang free and not contact an interior surface.
. Liquid-type air fresheners typically clip
on the vents. These products can cause
immediate damage and discoloration
when spilled on interior surfaces.
Carefully read and follow the manufac-
turer ’ s instructions before using air fresh-
eners.
FLOOR MATS GUID-D61B91F3-8DFF-4E86-867F-52D47A9504E1
WARNING To avoid potential pedal interference that
may result in a collision or injury:
. NEVER place a floor mat on top of
another floor mat in the driver front
position.
. Use only genuine NISSAN floor mats
specifically designed for use in your
vehicle model. See your INFINITI retailer
for more information.
. Properly position the mats in the floor-
well using the floor mat positioning aid.
See “ Floor mat positioning aid ” (P.7-6).
The use of genuine NISSAN floor mats can
extend the life of your vehicle carpet and make it easier to clean the interior. Mats
should be maintained with regular clean-
ing and replaced if they become exces-
sively worn.

Keep the floor mat away from the pedal.
Automatic transmission P (Park) mechan-
ism: On a fairly steep hill, check that your
vehicle is held securely with the selector
lever in the P (Park) position without
applying any brakes.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly
goes down further than normal, the pedal
feels spongy or the vehicle seems to take
longer to stop, see an INFINITI retailer
immediately. Keep the floor mat away from
the pedal.
Brakes: Check that the brakes do not pull
the vehicle to one side when applied.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjusted, see an INFINITI
retailer.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, an-
chors, adjuster and retractors) operate
properly and smoothly, and are installed securely. Check the belt webbing for cuts,
fraying, wear or damage.
Seats: Check seat position controls such as
seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head restraints move up
and down smoothly and that the locks (if
so equipped) hold securely in all latched
positions.

Under the hood and vehicle GUID-29B64B94-E77F-40DC-A4B2-6B5D542860ED
The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel). Battery*: Check the fluid level in each cell.
It should be between the MAX and MIN
lines. Vehicles operated in high tempera-
tures or under severe condition require
frequent checks of the battery fluid level.
Brake fluid level*: Make sure that the
brake fluid level is between the MAX and
MIN lines on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no belt
is frayed, worn, cracked or oily.
Engine oil level*: Check the level after
parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, im-
mediately have the exhaust system in-
spected by an INFINITI retailer. (See
“ Precautions when starting and driving ”
(P.5-3) for exhaust gas (Carbon monoxide).)
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
