The transmission shifts to the lower range.
When canceling the manual shift mode,
return the selector lever to the D (Drive)
position. The transmission returns to the
normal driving mode.
When you pull the paddle shifter while in
the D (Drive) position, the transmission will
shift to the upper or lower range tempora-
rily. The transmission will automatically
return to the D (Drive) position after a short
period of time. If you want to return to the
D (Drive) position manually, pull and hold
the paddle shifter for about 1.5 seconds.
In the manual shift mode, the shift range is
displayed on the position indicator in the
meter.
Shift ranges up or down one by one as
follows:
M1?
/M2?
/M3?
/M4?
/M5?
/M6?
/M7
M7 (7th):GUID-D73A39BF-43C8-459F-9C24-47B7F579C407Use this position for all normal forward
driving at highway speeds.
M6 (6th) andM5 (5th):GUID-D73A39BF-43C8-459F-9C24-47B7F579C407Use this position when driving up long
slopes, or for engine braking when driving
down long slopes.
M4 (4th),M3 (3rd) andM2 (2nd):GUID-D73A39BF-43C8-459F-9C24-47B7F579C407Use for hill climbing or engine braking on
downhill grades.
M1 (1st):GUID-D73A39BF-43C8-459F-9C24-47B7F579C407Use 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.

GUID-06BB20B5-DB70-4A4E-BFAD-8895E4D6A7ADFor 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-safeGUID-95D61986-6CBA-49FB-BC3E-01783BEA6F87When 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.

Start the vehicle in 1st gear and shift to
2nd, 3rd, 4th and 5th up to 6th gear in
sequence according to vehicle speed.
To back up, depress the shift lever and
then move it to the R (Reverse) position
after stopping the vehicle completely.
The shift lever returns to its original
position when the shift lever is moved to
the N (Neutral) position.
If it is difficult to move the shift lever into
the R (Reverse) or 1st gear, shift the N
(Neutral) position, and then release the
clutch pedal once. Fully depress the clutch
pedal again and shift into the R (Reverse)
or 1st gear.
Suggested upshift speedsGUID-9EB81786-00D6-483B-9F80-6CBD654C9817The following are suggested vehicle
speeds for shifting into a higher gear.
These suggestions relate to fuel economy

GUID-32536B6C-4378-49EB-9FE2-8A7EE457E3F0The 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.

CAUTION
During 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-A0B243EA-7BDA-4E12-AEC1-2F8D7AC85AA5. 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.

MoistureGUID-7FBD9AD0-A494-41FE-925A-A556AAC1FD1AAccumulation of sand, dirt and water on
the vehicle body underside can accelerate
corrosion. Wet floor coverings will not dry
completely inside the vehicle, and should
be removed for drying to avoid floor panel
corrosion.
Relative humidityGUID-790CCDC7-6B13-40A5-BC81-1395D1E39F89Corrosion will be accelerated in areas of
high relative humidity, especially those
areas where the temperatures stay above
freezing where atmospheric pollution ex-
ists, or where road salt is used.
TemperatureGUID-EDC9DACB-1841-4023-9ED0-FBD31E105BD6A temperature increase will accelerate the
rate of corrosion to those parts which are
not well ventilated.
Air pollutionGUID-70BE0465-57C4-480E-BA8E-73D881DEFA3EIndustrial pollution, the presence of salt in
the air in coastal areas, or heavy road salt
use will accelerate the corrosion process.
Road salt will also accelerate the disinte-
gration of paint surfaces.
TO PROTECT YOUR VEHICLE FROM
CORROSION
GUID-4521457A-D90E-41D2-9632-6C44281C5DB1. Wash and wax your vehicle often to
keep the vehicle clean.
. Always check for minor damage to the
paint and repair it as soon as possible.
. Keep drain holes at the bottom of the
doors open to avoid water accumula-
tion.
. Check the underbody for accumulation
of sand, dirt or salt. If present, wash
with water as soon as possible.
CAUTION
. NEVER remove dirt, sand or other debris
from the passenger compartment by
washing it out with a hose. Remove dirt
with a vacuum cleaner.
. Never allow water or other liquids to
come in contact with electronic compo-
nents inside the vehicle as this may
damage them.
Chemicals used for road surface deicing
are extremely corrosive. They accelerate
corrosion and deterioration of underbody
components such as the exhaust system,
fuel and brake lines, brake cables, floor
pan and fenders.
In winter, the underbody must be cleaned
periodically.
For additional protection against rust and
corrosion, which may be required in some
areas, consult an INFINITI retailer.

smooth operation and make sure the pedal
does not catch or require uneven effort.
Keep the floor mat away from the pedal.
Automatic transmission P (Park) mechan-
ism:On a fairly steep hill, check that the
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, adjusters 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 recliners, 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.
Steering wheel: Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washers operate properly
and that the wipers do not streak.
Under the hood and vehicleGUID-6687B186-528E-4C5C-A54D-1DCA274537D4The 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 and clutch fluid levels*:
Make sure
that the brake and clutch fluid levels are
between the MAX and MIN lines on the
reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belt*: Make sure that the
drive belt is not frayed, worn, cracked or
oily.
Engine oil level*: Check the level after
parking the vehicle on a level surface 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
dripping from the air conditioner after use
is normal. If you should notice any leaks or
if gasoline fumes are evident, check for the
cause and have it corrected immediately.
Power steering fluid level* and lines:
Check the level with the engine off. Check
the lines for proper attachment, leaks,
cracks, etc.
Radiator and hoses:Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust.
It is very important to remove these
substances, otherwise rust will form on
the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter,
the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt may
accumulate. For additional information,
see “Cleaning exterior” (P.7-2).
Windshield washer fluid*: Check that there
is adequate fluid in the reservoir.
GUID-10AF39EE-6E4C-416A-9D4D-B725EAC05CA0When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
. Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from
moving. For manual transmission mod-
els, move the shift lever to N (Neutral).
For automatic transmission models,
move the selector lever to P (Park).
. Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
. Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
. Never leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
. If you must work with the engine
running, keep your hands, clothing, hair and tools away from moving fans, belts
and any other moving parts.
. It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
. Always wear eye protection whenever
you work on your vehicle.
. If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
. Never get under the vehicle while it is
supported only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Keep smoking materials, flame and
sparks away from fuel tank and the
battery.
. Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition key is in the OFF position and
the engine is not running. To avoid
injury, always disconnect the negative
battery cable before working near the
fan.

MAINTENANCE PRECAUTIONS

8-6Maintenance and do-it-yourself
.The fuel filter or fuel lines should be
serviced by an INFINITI retailer because
the fuel lines are under high pressure
even when the engine is off.
CAUTION
.Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
. Avoid direct contact with used engine oil
and coolant. Improperly disposed engine
oil, coolant, and/or other vehicle fluids
can damage the environment. Always
conform to local regulations for disposal
of vehicle fluid.
This “8. Maintenance and do-it-yourself”
section gives instructions regarding only
those items which are relatively easy for an
owner to perform.
