properly. Have the brake system checked and, if
necessary, repaired by a NISSAN dealer
promptly. Avoid high-speed driving and abrupt
braking. For additional information, refer to “Anti-
lock Braking System (ABS) warning light” in this
section.
Charge warning light
If this light comes on while the engine is running,
it may indicate the charging system is not func-
tioning properly. Turn the engine off and check
the generator belt. If the belt is loose, broken,
missing, or if the light remains on, see a NISSAN
dealer immediately.
CAUTION
Do not continue driving if the generator
belt is loose, broken or missing.
Door open warning light
This light comes on when any of the doors are not
closed securely while the ignition switch is
placed in the ON position.
Engine oil pressure warninglight
This light warns of low engine oil pressure. If the
light flickers or comes on during normal driving,
pull off the road in a safe area, stop the engine
immediately, and call a NISSAN dealer or other
authorized repair shop.
The engine oil pressure warning light is not
designed to indicate a low oil level. Use the
dipstick to check the oil level. For additional in-
formation, refer to “Engine oil” in the “Mainte-
nance and do-it-yourself” section of this manual.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause se-
rious damage to the engine almost imme-
diately. Such damage is not covered by
warranty. Turn off the engine as soon as it
is safe to do so.
Low fuel warning light
This light comes on when the fuel level in the fuel
tank is getting low. Refuel as soon as it is conve-
nient, preferably before the fuel gauge reaches 0
(Empty) . There will be a small reserve of fuel
in the tank when the fuel gauge reaches 0
(Empty) .
Low tire pressure warning light
Your vehicle is equipped with a TPMS that moni-
tors the tire pressure of all tires except the spare.
The low tire pressure warning light warns of low
tire pressure or indicates that the TPMS is not
functioning properly.
After the ignition switch is placed in the ON
position, this light illuminates for about 1 second
and turns off.
Low tire pressure warning:
If the vehicle is being driven with low tire
pressure, the warning light will illuminate.
A CHECK TIRE PRES warning message is
also displayed in the odometer.
When the low tire pressure warning light illu-
minates, you should stop and adjust the tire
pressure of all four tires to the recommended
COLD tire pressure shown on the Tire and
Loading Information label located in the driv-
er’s door opening. The low tire pressure warn-
ing light does not automatically turn off when
the tire pressure is adjusted. After the tire is
inflated to the recommended pressure, the ve-
hicle must be driven at speeds above 16 mph
(25 km/h) to activate the TPMS and turn off the
low tire pressure warning light. Use a tire pres-
sure gauge to check the tire pressure.
2-16Instruments and controls

When the power steering warning light illumi-
nates with the engine running, there will be no
power assist for the steering, but you will still
have control of the vehicle. At this time, greater
steering effort is required to operate the steering
wheel, especially in sharp turns and at low
speeds.
For additional information, refer to “Power steer-
ing” in the “Starting and driving” section of this
manual.
P position selecting warninglight (CVT models)
The light blinks red and the warning buzzer
sounds if you are outside of the vehicle with the
Intelligent Key and the engine is off, but the shift
lever is not in the P (Park) position.
When the warning light blinks, place the ignition
switch in the ON position, move the shift lever to
the P (Park) position, then place the ignition
switch in the LOCK position.
Seat belt warning light andchime
The light and chime remind you to fasten your
seat belts. The light illuminates whenever the
ignition switch is placed in the ON or START
position and remains illuminated until the driver’s
seat belt is fastened. At the same time, the chime sounds for about 6 seconds unless the driver’s
seat belt is securely fastened.
The seat belt warning light may also illuminate if
the front passenger’s seat belt is not fastened
when the front passenger’s seat is occupied . For
7 seconds after the ignition switch is placed in
the ON position, the system does not activate the
warning light for the front passenger.
For additional information, refer to “Seat belts” in
the “Safety—Seats, seat belts and supplemental
restraint system” section of this manual.
Supplemental air bag warning
light
When the ignition switch is placed in the ON or
START position, the supplemental air bag warn-
ing light illuminates for about 7 seconds and then
turns off. This means the system is operational.
If any of the following conditions occur, the front
air bag, side air bag, curtain air bag, and preten-
sioner seat belt systems need servicing and your
vehicle must be taken to a NISSAN dealer:
● The supplemental air bag warning light re-
mains on after approximately 7 seconds.
● The supplemental air bag warning light
flashes intermittently. ●
The supplemental air bag warning light does
not come on at all.
Unless checked and repaired, the supplemental
restraint system (air bag system) and/or the pre-
tensioners may not function properly. For addi-
tional information, refer to “Supplemental re-
straint system (SRS)” in the “Safety—Seats, seat
belts and supplemental restraint system” section
of this manual.
WARNING
If the supplemental air bag warning light
is on, it could mean that the front air bag,
side air bag, curtain air bag systems
and/or pretensioner systems will not op-
erate in an accident. To help avoid injury to
yourself or others, have your vehicle
checked by a NISSAN dealer as soon as
possible.

off after a few driving trips. If the
light
does not turn off after a few driving trips,
have the vehicle inspected by a NISSAN
dealer. You do not need to have your vehicle
towed to the dealer.
● MIL blinking — An engine misfire has been
detected which may damage the emission
control system. To reduce or avoid emission
control system damage:
– do not drive at speeds above 45 mph (72 km/h).
– avoid hard acceleration or deceleration.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo being hauled or towed.
The MIL may stop blinking and come on steady.
Have the vehicle inspected by a NISSAN dealer. You
do not need to have your vehicle towed to the dealer.
CAUTION
Continued vehicle operation without hav-
ing the emission control system checked
and repaired as necessary could lead to
poor driveability, reduced fuel economy,
and possible damage to the emission con-
trol system.
Overdrive OFF indicator light
(CVT models)
The overdrive OFF indicator light illuminates
when the overdrive off mode is selected.

light while you are driving, have the Vehicle Dy-
namic Control system checked by a NISSAN
dealer.
While the Vehicle Dynamic Control system is
operating, you might feel a slight vibration or hear
the system working when starting the vehicle or
accelerating, but this is normal.
AUDIBLE REMINDERS
Brake pad wear warning
The disc brake pads have audible wear warnings.
When a disc brake pad requires replacement, it
makes a high pitched scraping sound when the
vehicle is in motion, whether or not the brake
pedal is depressed. Have the brakes checked as
soon as possible if the warning sound is heard.

2-22Instruments and controls

Your vehicle may have two types of security sys-
tems:● Vehicle security system (if so equipped)
● NISSAN Vehicle Immobilizer System
VEHICLE SECURITY SYSTEM (if so
equipped)
The vehicle security system provides visual and
audible alarm signals if someone opens the doors
when the system is armed. It is not, however, a
motion detection type system that activates when
a vehicle is moved or when a vibration occurs. The system helps detect vehicle theft but cannot
prevent it, nor can it prevent the theft of interior or
exterior vehicle components in all situations. Al-
ways secure your vehicle even if parking for a
brief period. Never leave your keys in the ignition,
and always lock the vehicle when unattended. Be
aware of your surroundings, and park in secure,
well-lit areas whenever possible.
Many devices offering additional protection, such
as component locks, identification markers, and
tracking systems, are available at auto supply
stores and specialty shops. A NISSAN dealer
may also offer such equipment. Check with your
insurance company to see if you may be eligible
for discounts for various theft protection features.
How to arm the vehicle security
system
1. Close all windows.
(The system can be
armed even if the windows are open.)
2. Place the ignition switch in the LOCK posi- tion and remove the key.
3. Close all doors. Lock all doors. The doors can be locked with:
● the power door lock switch (if the door is
opened, locked and then closed) .
● the key — master or mechanical (Intelli-
gent Key models) . ●
any request switch (Intelligent Key mod-
els) .
● the key fob or Intelligent Key.
Key fob and Intelligent Key operation:
● Push the
button. All doors lock.
The hazard lights flash twice and the horn
beeps once to indicate all doors are
locked.
● When the
button is pushed with
all doors locked, the hazard lights flash
twice and the horn beeps once as a re-
minder that the doors are already locked.
The horn may or may not beep. Refer to
“Silencing the horn beep feature” in the
“Pre-driving checks and adjustments” sec-
tion in this manual.
4. Confirm that the
indicator light comes
on. The
light stays on for about
30 seconds. The vehicle security system is
now pre-armed. After about 30 seconds the
vehicle security system automatically shifts
into the armed phase. The
light begins
to flash once every 3 seconds. If, during the
30-second pre-arm time period, the driver’s
door is unlocked by the key, a request
switch, the key fob or Intelligent Key, or if the
LIC0301
SECURITY SYSTEMS
Instruments and controls2-23

ignition switch is placed in the ACC or ON
position, the system will not arm.
● If the key is turned slowly when locking
the driver’s door, the system may not
arm. Furthermore, if the key is turned
beyond the vertical position toward the
unlock position to remove the key, the
system may be disarmed when the key
is removed. If the indicator light fails to
glow for a period of time, unlock the
door once and lock it again.
● Even when the driver and/or passen-
gers are in the vehicle, the system will
arm with all doors closed and locked
with the ignition switch placed in the
OFF position.
Vehicle security system activation
The vehicle security system will give the following
alarm:
● The headlights blink and the horn sounds
intermittently. ●
The alarm automatically turns off after a pe-
riod of time. However, the alarm reactivates if
the vehicle is tampered with again. The alarm
can be shut off by unlocking the driver’s door
with the key, a request switch, by pressing
the
button on the key fob or Intelligent
Key or placing the ignition switch in the ON
or ACC position.
The alarm is activated by:
● opening a door without using the key, a
request switch, key fob or Intelligent Key
(even if the door is unlocked by using the
inside lock knob or the power door lock
switch) .
How to stop an activated alarm
The alarm stops only by unlocking the driver’s
door by pressing the
button on the key fob
or Intelligent Key, or by unlocking all doors with
any request switch (Intelligent Key models) or
placing the ignition switch in the ON or ACC
position.
NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System will not
allow the engine to start without the use of a
registered key.
If the engine fails to start using a registered key
(for example, when interference is caused by
another registered key, an automated toll road
device or automatic payment device on the key
ring) , restart the engine using the following pro-
cedures:
1. Leave the ignition switch placed in the ON position 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 device (which may have caused the interference)
separate from the registered key.
If the no start condition re-occurs, NISSAN rec-
ommends placing the registered key on a sepa-
rate key ring to avoid interference from other
devices.
