d. You have had an accident involv-
ing damage to the exhaust system,
underbody, or rear of the vehicle.
THREE WAY CATALYST The three way catalyst is an emission control
device installed in the exhaust system. Ex-
haust gases in the converter are burned at
high temperatures to help reduce pollutants.
WARNINGO The exhaust gas and the exhaust sys-
tem are very hot. Keep people, ani-
mals or flammable materials away
from the exhaust system compo-
nents.
O 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. CAUTION O Do not use leaded gasoline. Deposits
from leaded gasoline seriously re-
duce the three way catalyst's ability
to help reduce exhaust pollutants.
O Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause over-
rich fuel flow into the three way cata-
lyst, causing it to overheat. Do not
keep driving if the engine misfires, or
if noticeable loss of performance or
other unusual operating conditions
are detected. Have the vehicle in-
spected promptly by an authorized
INFINITI retailer.
O Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three way catalyst.
O Do not race the engine while warming
it up.
O Do not push or tow your vehicle to
start the engine. AVOIDING COLLISION AND
ROLLOVER
WARNING Failure to operate this vehicle in a safe
and prudent manner may result in loss
of control or an accident.
Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid excessive
speed, high speed cornering, or sudden steer-
ing maneuvers, because these driving prac-
tices could cause you to lose control of your
vehicle. As with any vehicle, a loss of con-
trol could result in a collision with other
vehicles or objects, or cause the vehicle to
rollover, particularly if the loss of control
causes the vehicle to slide sideways. Be
attentive at all times, 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
drowsiness). Always wear your seat belt. See
ªSeat Beltsº in the ª1. Seats, restraints and
supplemental air bag systemsº section. Also
instruct your passengers to do so.

This position activates the starter motor, start-
ing the engine.
INFINITI VEHICLE IMMOBILIZER
SYSTEM The Infiniti Vehicle Immobilizer System will not
allow the engine to start without the use of the
registered Infiniti Vehicle Immobilizer System
key.
If the engine fails to start using the registered
Infiniti Vehicle Immobilizer System key, it may
be due to interference caused by another
Infiniti Vehicle Immobilizer System key, an
automated toll road device or automated pay-
ment device on the key ring. Restart the en-
gine using the following procedures: 1. Leave the ignition switch in the ON position
for approximately 5 seconds.
2. Turn the ignition switch to the OFF or LOCK
position and wait approximately 10 sec-
onds.
3. Repeat step 1 and 2 again.
4. Restart the engine while holding the device
(which may have caused the interference)
separate from the registered Infiniti Vehicle
Immobilizer System key.
If this procedure allows the engine to start,
INFINITI recommends placing the registered
Infiniti Vehicle Immobilizer System key on a
separate key ring to avoid interference from
other devices.

AUTOMATIC TRANSMISSION
5 speed automatic transmission The automatic transmission in your vehicle is
electronically controlled by a transmission con-
trol module to produce maximum power and
smooth operation.
Shown on the following pages are the recom-
mended operating procedures for this trans-
mission. Follow these procedures for maxi-
mum vehicle performance and driving
enjoyment.
Starting the vehicle After starting the engine, fully depress the foot
brake pedal and push the selector lever button
before shifting the selector lever to the R
(Reverse), N (Neutral), D (Drive) or Manual
shift mode position. Be sure the vehicle is fully
stopped before attempting to shift the selector
lever.
This automatic transmission model is de-
signed so that the foot brake pedal must be
depressed before shifting from P (Park) to
any drive position while the ignition switch
is ON.
The selector lever cannot be moved out of
P (Park) position and into any of the other
gear positions if the ignition key is turned to the LOCK, OFF or ACC position or if the
key is removed from the switch.
1. Keep the foot brake pedal depressed and
push the selector lever button to shift into a
driving gear.
2. Release the parking brake and foot brake,
then gradually start the vehicle in motion.
WARNING O Do not depress the accelerator pedal
while shifting from P (Park) or N (Neu-
tral) to R (Reverse), D (Drive) or
manual shift mode. Always depress
the brake pedal until shifting is com-
pleted. Failure to do so could cause
you to lose control and have an acci-
dent.
O Cold engine idle speed is high, so use
caution when shifting into a forward
or reverse gear before the engine has
warmed up.
O On slippery roads, do not downshift.
This may cause a loss of control.
O Never shift to P (Park) or R (Reverse) while vehicle is moving forward.
Never shift to P (Park) or D (Drive)
while vehicle is moving rearward.
These could cause an accident.
CAUTION When stopping the vehicle on an uphill
grade, do not hold the vehicle by de-
pressing the accelerator pedal. The foot
brakes should be used for this purpose.DRIVING THE VEHICLE

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

manual shift mode. Shift range can be se-
lected manually.
In the manual shift mode, the shift range is
displayed on the position indicator in the
meter. When shifting the selector lever to the
manual shift gate, the position indicator first
displays 4 M
(4th).
Shift ranges up or down one by one as follows: 1 M

5 M
(5th):
Use this position for all normal forward driving.
4 M
(4th):
For driving up or down long slopes where
engine braking would be advantageous.
3 M
(3rd) and 2 M
(2nd):
Use for hill climbing or engine braking on
downhill grades.
1 M
(1st):
Use this position when climbing steep hills
slowly or driving slowly through deep snow,
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 4 M
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 The transmission will automatically shift the
gears between the 1st and the selected
range. (For example, if you select the 3rd
range, the transmission will shift up or down
between 1st, 2nd and 3rd gears.
O Moving the selector lever rapidly to the
same side twice will shift the ranges in
succession.
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.
O In the manual shift mode, the transmis-
sion may shift up automatically over the
selected range, if the engine is revved
up to the hazardous speed. When the
vehicle speed decreases, the transmis-
sion automatically shifts down and shifts to 1st gear before the vehicle
comes to a stop.
Manual shift mode (Coupe) When the selector lever is shifted from D to the
manual shift gate with the vehicle stopped or
while driving, the transmission enters the
manual shift mode. Shift range can be se-
lected manually.
In the manual shift mode, the shift range is
displayed on the position indicator in the

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.

If it is difficult to move the shift lever into R
(Reverse) or 1 (Low gear), shift into N (Neu-
tral), then release the clutch pedal and shift
into R or 1 again.
WARNINGO Do not downshift abruptly on slippery
roads. This may cause a loss of con-
trol.
O Do not over-rev the engine when
shifting to a lower gear. This may
cause a loss of control or engine
damage.
CAUTIONO Do not rest your foot on the clutch
pedal while driving. This may damage
the clutch.
O Stop your vehicle completely before
shifting into R (Reverse).
O When the vehicle is stopped for a
period of time, for example at a stop
light, shift to N (Neutral) and release the clutch pedal with the foot brake
applied.
Suggested up-shift speeds Shown below are suggested vehicle speeds
for shifting into a higher gear. These sugges-
tions relate to fuel economy and vehicle per-
formance. Actual up-shift speeds will vary ac-
cording to road conditions, the weather and
individual driving habits.

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.
O Avoid driving for long periods at constant
speed, either fast or slow. Do not run the
engine over 4,000 rpm.
O Do not accelerate at full throttle in any gear.
O Avoid quick starts.
O Avoid hard braking as much as possible.
O Do not tow a trailer for the first 500 miles
(800 km). O Accelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
O Drive at moderate speeds on the highway.
Driving at high speed will lower fuel
economy.
O Avoid unnecessary stopping and braking.
Maintain a safe distance behind other ve-
hicles.
O Use a proper gear range which suits road
conditions. On level roads, shift into high
gear as soon as possible.
O Avoid unnecessary engine idling. O Keep your engine tuned up.
O Follow the recommended periodic mainte-
nance schedule.
O Keep the tires inflated at the correct pres-
sure. Low pressure will increase tire wear
and waste fuel.
O Keep the front wheels in correct alignment.
Improper alignment will cause not only tire
wear but also lower fuel economy.
O Air conditioner operation lowers fuel
economy. Use the air conditioner only when
necessary.
O When cruising at highway speeds, it is
more economical to use the air conditioner
and leave the windows closed to reduce
drag. SD1001M
