– Your vehicle is in an area where it isdifficult to receive cellular signal; such
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
voice during a call.
• Immediately af ter the ignition switch is placed in the ON position, it may be im-
possible to receive a call for a short period
of time.
• Do not place the cellular phone in an area surrounded by metal or far away from
the in-vehicle phone module to prevent
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.
The Bluetooth® Hands-Free Phone Sys-
tem cannot charge cellular phones. • If the hands-free phone system seems to
be malfunctioning, refer to “Trouble-
shooting guide” in this section. You can
also visit www.nissanusa.com/bluetooth
or www.nissan.ca/bluetooth for trouble-
shooting help.
• 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.
• Refer to the cellular phone owner's manual regarding the telephone
charges, cellular phone antenna and
body, etc.
• The signal strength display on the moni- tor will not coincide with the signal
strength display of some cellular phones.

•Always use tires of the same type,
size, brand, construction (bias, bias-
belted, or radial), and tread pattern
on all four wheels. Install tire chains
on the rear wheels when driving on
slippery roads and drive carefully.
• Be sure to check the brakes immedi-
ately af ter driving in mud or water.
For additional information, refer to
“Wet brakes” in this section.
• Avoid parking your vehicle on steep
hills. If you get out of the vehicle and
it rolls forward, backward or side-
ways, you could be injured.
• Whenever you drive off-road through
sand, mud or water as deep as the
wheel hub, more frequent mainte-
nance may be required. For addi-
tional information, refer to “Mainte-
nance under severe operating
conditions” in the “Maintenance and
schedules” section of this manual.
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, the ignition
switch position will illuminate 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 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 procedures:
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 windshield-washer fluid
as frequently 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.
• Check that all doors are closed.
• Position seat and adjust head restraints/ headrests.
• Adjust inside and outside mirrors.
• Fasten the seat belt and ask all passen- gers 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. Move the shif t lever to P (Park) or N (Neu-
tral). P (Park) is recommended.
The starter is designed not to operate
unless the shif t lever is in either P
(Park) or N (Neutral).
3. Push the ignition switch to the ON posi- tion. Depress the brake pedal 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
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

CAUTION
• To avoid possible damage to your ve-
hicle, when stopping the vehicle on
an uphill grade, do not hold the ve-
hicle by depressing the accelerator
pedal. The foot brake should be used
for this purpose.
The A/T in your vehicle is electronically con-
trolled to produce maximum power and
smooth operation.
The recommended operating procedures
for this transmission are shown on the fol-
lowing pages. Follow these procedures for
maximum vehicle performance and driv-
ing enjoyment.
Starting the vehicle
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. The automatic transmission is designed
so the foot brake pedal MUST be de-
pressed before shif ting from P (Park) to
any drive position while the ignition
switch is in the ON position.
The shif t lever cannot be moved out of
the P (Park) position and into any of the
other gear positions if the ignition
switch is placed in the LOCK or OFF posi-
tion.
The shif t lever may not be moved out of
the P (Park) position and into any of the
other gear positions if the ignition
switch is placed in the ON position, but
the engine is not running and the out-
side temperature is extremely low.
