as in a tunnel, in an underground park-
ing garage, near a tall building or in a
mountainous area.
– Your cellular phone is locked to prevent it from being dialed.
• When the radio wave condition is not ideal or ambient sound is too loud, it may
be difficult to hear the other person's

tone quality degradation and wireless
connection disruption.
• While a cellular phone is connected through the Bluetooth® wireless connec-
tion, the battery power of the cellular
phone may discharge quicker than usual.

tem cannot charge cellular phones. • Some cellular phones or other devices
may cause interference or a buzzing
noise to come from the audio system
speakers. Storing the device in a different
location may reduce or eliminate the
noise.

WARNING
• Do not leave children or adults who
would normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
• Closely supervise children when they
are around cars to prevent them
from playing and becoming locked in
the trunk where they could be seri-
ously injured. Keep the car locked,
with the rear seatback and trunk lid
securely latched when not in use, and
prevent children's access to car keys.
EXHAUST GAS (carbon monoxide)
air recirculation but-
ton to off and the fan control dial
to high to circulate the air.
• If electrical wiring or other cable con-
nections must pass to a trailer
through the seal on the trunk lid or
the body, follow the manufacturer's
recommendation to prevent carbon
monoxide entry into the vehicle. •
The exhaust system and body should
be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involv- ing damage to the exhaust sys-
tem, underbody, or rear of the
vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst
are burned at high temperatures to help
reduce pollutants.

WARNING
Do not operate the push-button igni-
tion switch while driving the vehicle ex-
cept in an emergency. (The engine will
stop when the ignition switch is pushed
three consecutive times in quick suc-
cession or the ignition switch is pushed
and held for more than 2 seconds.) If
the engine stops while the vehicle is
being driven, this could lead to a crash
and serious injury. When the ignition switch is pushed without
depressing the brake pedal or the clutch
pedal for manual transmission (M/T) mod-
els, the ignition switch position will illumi-
nate as follows:
Push center:
• Once to change to ACC.
• Two times to change to ON.
• Three times to return to OFF.
The ignition switch will automatically re-
turn to the LOCK position when any door is
either opened or closed with the switch in
the OFF position.
The ignition lock is designed so that the
ignition switch position cannot be placed
in the OFF position until the shif t lever is
moved to the P (Park) position or N (Neutral)
position (M/T).
When the ignition switch cannot be pushed
toward the OFF position, proceed as fol-
lows:
1. Move the shif t lever to the P (Park) posi-
tion or N (Neutral) position (M/T).
2. Push the ignition switch. The ignition switch position will change to the ON
position. 3. Push the ignition switch again to the
OFF position.
The shif t lever can be moved from the P
(Park) position if the ignition switch is in
the ON position and the brake pedal is
depressed.
If the battery of the vehicle is discharged,
the ignition switch cannot be moved
from the LOCK position.
Some indicators and warnings for opera-
tion are displayed in the meter. For addi-
tional information, refer to “Warning lights,
indicator lights and audible reminders” in
the “Instruments and controls” section of
this manual.

NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the engine to start without
the use of the registered key.
If the engine fails to start using a registered
key (for example, when interference is
caused by another registered key, an auto-
mated toll road device or automatic pay-
ment device on the key ring), restart the
engine using the following procedure:
1. Leave the ignition switch in the ON posi-tion for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the de- vice (which may have caused the inter-
ference) separate from the registered
key.
If the no start condition re-occurs, NISSAN
recommends placing the registered key on
a separate key ring to avoid interference
from other devices. • Make sure the area around the vehicle is
clear.
• Check fluid levels such as engine oil, cool- ant, brake and clutch fluid (if so equipped),
and windshield-washer fluid as fre-
quently as possible, or at least whenever
you refuel.
• Check that all windows and lights are clean.
• Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
• Lock all doors.
• Position seat and adjust head restraints/ headrests.
• Adjust inside and outside mirrors.
• Fasten seat belts and ask all passengers to do likewise.
• Check the operation of warning lights when the ignition switch is placed in the
ON position. For additional information,
refer to “Warning lights, indicator lights
and audible reminders” in the “Instru-
ments and controls” section of this
manual. 1. Apply the parking brake.
2.
Continuously Variable Transmission
model:
Move the shif t lever to P (Park) or N (Neu-
tral). P (Park) is recommended.
The starter is designed not to operate
if the shif t lever is in any of the driving
positions.
Manual Transmission (M/T) model:
Move the shif t lever to N (Neutral). De-
press the clutch pedal to the floor.
The starter is designed not to operate
unless the clutch pedal is fully de-
pressed.
3. Push the ignition switch to the ON posi- tion. Depress the brake pedal and the
clutch pedal (if so equipped) and push
the ignition switch to start the engine.
To start the engine immediately, push
and release the ignition switch while de-
pressing the brake pedal with the igni-
tion switch in any position.
• If the engine is very hard to start in extremely cold weather or when re-
starting, depress the accelerator
pedal a little (approximately 1/3 to the
BEFORE STARTING THE ENGINE STARTING THE ENGINE
5-14Starting and driving

floor) and while holding, crank the en-
gine. Release the accelerator pedal
when the engine starts.
• If the engine is very hard to start be- cause it is flooded, depress the accel-
erator pedal all the way to the floor
and hold it. Push the ignition switch to
the ON position to start cranking the
engine. Af ter 5 or 6 seconds, stop
cranking by pushing the ignition
switch to the LOCK position. Af ter
cranking the engine, release the accel-
erator pedal. Crank the engine with
your foot off the accelerator pedal by
depressing the brake pedal and push-
ing the ignition switch to start the en-
gine. If the engine starts, but fails to
run, repeat the above procedure.

CAUTION
To avoid possible damage to your ve-
hicle, when stopping the vehicle on an
uphill grade, do not hold the vehicle by
depressing the accelerator pedal. The
foot brake should be used for this pur-
pose.
1. Af ter starting the engine, fully depress the foot brake pedal before moving the
shif t lever out of the P (Park) position.
2. Keep the foot brake pedal depressed and move the shif t lever into a driving
gear.
3. Release the foot brake, then gradually start the vehicle in motion.
4. Stop the vehicle completely before mov- ing the shif t lever into the P (Park)
position.
The Continuously Variable Transmission
is designed so the foot brake pedal MUST
be depressed before shif ting from P
(Park) to any drive position while the ig-
nition switch is in the ON position.
The shif t lever cannot be moved out of P
(Park) and into any of the other gear po-
sitions if the ignition switch is placed in
