To move the selector lever,
: Push the button while depressing the
brake pedal,
: Push the button,
: Just move the selector lever.
Shifting After starting the engine, fully depress the
brake pedal and shift the selector lever from P
(Park) to R (Reverse), N (Neutral), D (Drive),
or Manual shift mode position.
Push the button to shift into P (Park) or R
(Reverse). All other positions can be selected
without pushing the button. WARNING Apply the parking brake if the selector
lever is in any position while the engine
is not running. Failure to do so could
cause the vehicle to move unexpectedly
or roll away and result in serious per-
sonal injury and/or property damage.
If the key is turned to OFF or ACC for any
reason while the vehicle is in R (Reverse), N
(Neutral), or any D (Drive) position, the key
cannot be turned to LOCK and be removed
from the ignition switch. Move the selector
lever to P (Park) position, then the key can be
turned to LOCK.
P (Park):
Use this selector position when the vehicle is
parked or when starting the engine. Make sure
the vehicle is completely stopped. The brake
pedal must be depressed and the selector
lever button pushed in to move the selector
lever from N (Neutral) or any drive position
to P (Park). Apply the parking brake. When
parking on a hill, apply the parking brake first,
then move the lever to the P (Park) position. CAUTION Use this position only when the vehicle
is completely stopped.
R (Reverse):
Use this position to back up. Always be sure
the vehicle is completely stopped before se-
lecting R (Reverse). The brake pedal must
be depressed and the selector lever button
pushed in to move the selector lever from P
(Park), N (Neutral) or any drive position to R
(Reverse).
N (Neutral):
Neither forward nor reverse gear is engaged.
The engine can be started in this position. You
may shift to N (Neutral) and restart a stalled
engine while the vehicle is moving.
D (Drive):
Use this position for all normal forward driving.
Manual shift mode (Sedan) When the selector lever is shifted from D to the
manual shift gate with the vehicle stopped or
while driving, the transmission enters theSSD0240

sand or mud, or for maximum engine braking
on steep downhill grades.
O Remember not to drive at high speeds for
extended periods of time in lower than M
4
range. This reduces the fuel economy.
O When shifting up, move the selector lever to
the + (up) side. (Shifts to higher range.)
O When shifting down, move the selector
lever to the þ (down) side. (Shifts to lower
range.)
O Moving the selector lever to the same side
twice will shift the ranges in succession.
However, if this motion is rapidly done, the
second shifting may not be completed prop-
erly.
O 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.
O When canceling the manual shift mode,
return the selector lever to the D position.
The transmission returns to the normal
driving mode.
O In the manual shift mode, the transmis-
sion may not shift to the selected gear.
This helps maintain driving performance and reduces the chance of vehicle dam-
age or loss of control.
Accelerator downshift
Ð In D position Ð For passing or hill climbing, fully depress the
accelerator pedal to the floor. This shifts the
transmission down into the lower gear, de-
pending on the vehicle speed.
Fail-safe When the fail-safe operation occurs, the next
time the key is turned to the ON position, the
light will blink for approximately 8 sec-
onds after coming on for 2 seconds. While the
vehicle can be driven under these circum-
stances please note that the gears in the
automatic transmission will be locked in 4th
gear.
If the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
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, turn the ignition key
OFF and wait for 3 seconds. Then turn the
key back to the ON position. The vehicle
should return to its normal operating con-
dition. If it does not return to its normal
operating condition, have your INFINITI re- tailer check the transmission and repair if
necessary.

O HEADED UPHILL WITH CURB:
j 2
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
O HEADED UPHILL OR DOWNHILL, NO
CURB:
j 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.
4. Turn the ignition key to the LOCK position
and remove the key. The power assisted steering is designed to
use a hydraulic pump, driven by the engine, to
assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, espe-
cially in sharp turns or at low speeds.
WARNING If the engine is not running or is turned
off while driving, the power assist for the
steering will not work. Steering will be
much harder to operate. BRAKING PRECAUTIONS The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
Vacuum assisted brake
The brake booster aids braking by using en-
gine vacuum. If the engine stops, you can stop
the vehicle by depressing the brake pedal.
However, greater foot pressure on the brake
pedal will be required to stop the vehicle and
the stopping distance will be longer.
Wet brakes
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 pressing 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.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This overheats the brakes, in-
creases wear on the brake linings and pads,
and reduces gas mileage.POWER STEERING BRAKE SYSTEM

FREEING A FROZEN DOOR LOCK To prevent a door lock from freezing, apply
de-icer or glycerin to it through the key hole. If
the lock becomes frozen, heat the key before
inserting it into the key hole.
ANTI-FREEZE In the winter when it is anticipated that the
temperature will drop below 32ÉF (0ÉC), check
anti-freeze to assure proper winter protection.
For additional information, see ªEngine Cool-
ing Systemº in the ª8. Do-it-yourselfº section.
BATTERY If the battery is not fully charged during ex-
tremely 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 ªBatteryº in the ª8. Do-it-
yourselfº section.
DRAINING OF COOLANT WATER If the vehicle is to be left outside without
anti-freeze, drain the cooling system by open-
ing the drain plug located under the radiator.
Refill before operating the vehicle. See ªEn-
gine cooling systemº in the ª8. Do-it-yourselfº
section for changing engine coolant. TIRE EQUIPMENT 1. SUMMER tires are of a tread design 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.
Please consult your INFINITI retailer for the
tire type, size, speed rating and availability
information.
2. For additional traction on icy roads, studded
tires may be used. However, some prov-
inces and states prohibit their use. Check
local, state and provincial laws before in-
stalling 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.
3. Tire chains may be used if desired. Make
sure they are of proper size for the tires on
your vehicle and are installed according to
the chain manufacturer's suggestions. Use
of tire chains may be prohibited according
to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are of proper size
for the tires on your vehicle and are in- stalled according to the chain manufactur-
er's suggestions. Use only SAE Class S
chains. Class ªSº chains are used on ve-
hicles with restricted tire to vehicle clear-
ance. Vehicles that can use Class ªSº
chains are designed to meet the SAE stan-
dard minimum clearances between the tire
and the closest vehicle suspension or body
component required to accommodate the
use of a winter traction device (tire chains
or cables). The minimum clearances are
determined using the factory equipped tire
size. Other types may damage your ve-
hicle. Use chain tensioners when recom-
mended by the tire chain manufacturer to
ensure a tight fit. Loose end links of the tire
chain must be secured or removed to pre-
vent the possibility of whipping action dam-
age to the fenders or underbody. If pos-
sible, avoid fully loading your vehicle when
using tire chains. In addition, drive at a
reduced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling
and performance may be adversely af-
fected.
Never install tire chains on a T-type spare
tire. Do not use tire chains on dry roads.

When performing any inspection or mainte-
nance 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.
WARNINGO Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
N (Neutral) position. For an automatic
transmission, move the selector lever
to P (Park) position.
O Be sure the ignition key is OFF or
LOCK when performing any parts re-
placement or repairs.
O 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.
O It is advised to secure or remove any loose clothing and any jewelry, such
as rings, watches, etc. before work-
ing on your vehicle.
O Always wear eye protection when-
ever you work on your vehicle.
O 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.
O Never get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
O Keep smoking materials, flame and
sparks away from fuel and the bat-
tery.
O On gasoline engine models with the
Multiport Fuel Injection (MFI) System,
the fuel filter or fuel lines should be
serviced by an INFINITI retailer be-
cause the fuel lines are under high
pressure even when the engine is off. CAUTION O Do not work under the hood while the
engine is hot. Turn off the engine and
wait until it cools down.
O Never connect or disconnect either
the battery or any transistorized com-
ponent connector while the ignition
key is on.
O Never leave any engine or automatic
transmission related component har-
ness connector disconnected while
the ignition key is on.
O Avoid direct contact with used engine
oil and coolant. Improperly disposed
engine oil, engine coolant and/or
other vehicle fluids can hurt the envi-
ronment. Always conform to local
regulations for disposal of vehicle
fluid.

Check the fluid level in each cell. It should be
between the MAX and MIN lines.
If it is necessary to add fluid, add only distilled
water to bring the level to the indicator in each
filler opening. Do not overfill.
Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.
1. Remove the cell plugs.
2. Add distilled water up to the MAX level.
3. Tighten cell plugs. JUMP STARTING If jump starting is necessary, see ªJump start-
