2011 NISSAN ALTIMA HYBRID sensor

When the ignition switch is placed in the ON
position, the power steering warning light illumi-
nates. After the Hybrid System is in the READY
mode, the power steering warning light turns off.
This indicates the power steering system is op-
erational.
If the power steering warning light illuminates
while the Hybrid System is in the READY mode, it
may indicate the power steering system is not
functioning properly and may need servicing.
Have the power steering system checked by a
NISSAN dealer.
When the power steering warning light illumi-
nates with the Hybrid System in the READY
mode, there will be no power assist for the steer-
ing 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.
See “Power steering” in the “Starting and driving”
section.
Electronically controlled brakewarning light (yellow)
This light functions for both the regenerative
brake and electronically controlled brake sys-
tems. When the ignition switch is placed in the ON
position and the Hybrid System is in the READY
mode, the light stays on for about 2 seconds. If
the light comes on at any other time, it may
indicate the regenerative brake and/or the elec-
tronically controlled brake systems are not func-
tioning properly. Have the system checked by a
NISSAN dealer.
If the hydraulic brake warning light also comes on
with the parking brake not applied, stop the ve-
hicle immediately and call a NISSAN dealer. For
additional information, see
Brake systemin
Starting and Driving section.
WARNING
Your brake system may not be working
properly if both the brake warning light
and electronically controlled brake sys-
tem warning light come on when the Hy-
brid System is in READY mode and the
parking brake is not applied. Driving could
be dangerous. If you judge it to be safe,
drive carefully to the nearest service sta-
tion for repairs. Otherwise, have your ve-
hicle towed because driving could be
dangerous.
Engine oil pressure warning
light
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. See “Engine oil” in
the “Maintenance 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.
High temperature warning light
(red)
When the ignition switch is placed in the ON
position, the high temperature warning light illu-
minates and then turns off. This indicates that the
high temperature sensor in the engine coolant
system is operational.
2-12Instruments and controls

High beam indicator light(blue)
This blue light comes on when the headlight high
beams are on and goes out when the low beams
are selected.
The high beam indicator light also comes on
when the passing signal is activated.
Low temperature indicatorlight (blue)
The low temperature indicator light illuminates
when the engine coolant temperature is low.
When the ignition switch is placed in the ON
position, the low temperature indicator light illu-
minates and then turns off after the engine cool-
ant has warmed up.
If the low temperature indicator light stays illumi-
nated after the engine has sufficiently warmed
up, it may indicate the low temperature sensor in
the engine coolant system is not functioning
properly and may need servicing. Have the sys-
tem checked, and if necessary repaired, by a
NISSAN dealer promptly.
Malfunction Indicator Light(MIL)
If this indicator light comes on steady or blinks
while the Hybrid System is in READY mode, it
may indicate a potential emission control mal-
function.
The Malfunction Indicator Light may also come
on steady if the fuel-filler cap is loose or missing,
or if the vehicle runs out of fuel. Check to make
sure the fuel-filler cap is installed and closed
tightly, and that the vehicle has at least 3 gallons
(11.4 liters) of fuel in the fuel tank.
After a few driving trips, the
light should
turn off if no other potential emission control
system malfunction exists.
If this indicator light comes on steady for 20
seconds and then blinks for 10 seconds when
the engine is not running, it indicates that the
vehicle is not ready for an emission control sys-
tem inspection/maintenance test. See “Readi-
ness for inspection/maintenance (I/M) test” in the
“Technical and consumer information” section of
this manual.
Operation
The Malfunction Indicator Light will come on in
one of two ways: ●
Malfunction Indicator Light on steady — An
emission control system malfunction has
been detected. Check the fuel-filler cap if the
LOOSE FUEL CAP warning appears in the
vehicle information display. If the fuel-filler
cap is loose or missing, tighten or install the
cap and continue to drive the vehicle.
The
light should turn 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.
● Malfunction Indicator Light blinking — An
engine misfire has been detected which may
damage the emission control system. To re-
duce or avoid emission control system dam-
age:
– 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 Malfunction Indicator Light 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.
2-16Instruments and controls

Be sure you do not put anything on top of
the autolight sensor located on the top side
of the instrument panel. The autolight sen-
sor controls the autolight; if it is covered,
the autolight sensor reacts as if it is dark
out and the headlights will illuminate. If
this occurs while parked with the Hybrid
System off and the ignition switch placed
in the ON position, your vehicle’s battery
could become discharged.Headlight beam select
1To select the high beam function, push the
lever forward. The high beam lights come on
and the
light illuminates.
2Pull the lever back to select the low beam.
3Pulling and releasing the lever flashes the
headlight high beams on and off.
Battery saver system
If the ignition switch is placed in the OFF position
while the headlight switch is in the
orposition, the headlights will turn off after
5 minutes.
CAUTION
Even though the battery saver feature au-
tomatically turns off the headlights after a
period of time, you should turn the head-
light switch to the OFF position when the
engine is not running to avoid discharging
the vehicle battery.
DAYTIME RUNNING LIGHT SYSTEM
(Canada only)
The headlights automatically illuminate at a re-
duced intensity when the engine is started with
the parking brake released. The daytime running
lights operate with the headlight switch in the
OFF position or in the
position. Turn the
headlight switch to the
position for full
illumination when driving at night.
If the parking brake is applied before the engine is
started, the daytime running lights do not illumi-
nate. The daytime running lights illuminate when
the parking brake is released. The daytime run-
ning lights will remain on until the ignition switch
is placed in the OFF position.

OPERATING TIPS
●When the engine coolant temperature and
outside air temperature are low, the air flow
from the foot outlets may not operate for a
maximum of 150 seconds. However, this is
not a malfunction. After the coolant tempera-
ture warms up, air flow from the foot outlets
will operate normally.
The sunload sensor, located on the top of the
instrument panel on the driver’s side, helps the
system maintain a constant temperature. Do not
put anything on or around this sensor. The air conditioner system in your NISSAN ve-
hicle is charged with a refrigerant designed with
the environment in mind.
This refrigerant does not harm the earth’s
ozone layer.
Special charging equipment and lubricant is re-
quired when servicing your NISSAN air condi-
tioner. Using improper refrigerants or lubricants
will cause severe damage to your air conditioner
system. See “Air conditioner system refrigerant
and oil recommendations” in the “Technical and
consumer information” section of this manual.
A NISSAN dealer is able to service your “environ-
mentally friendly” air conditioning system.
WARNING
The air conditioner system contains re-
frigerant under high pressure. To avoid
personal injury, any air conditioner ser-
vice should be done only by an experi-
enced technician with proper equipment.

●When a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting.
● Replacing tires with those not originally
specified by NISSAN could affect the
proper operation of the TPMS.
● Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors.
CAUTION
Do not place metalized film or any metal
parts (antenna, etc.) on the windows. This
may cause poor reception of the signals
from the tire pressure sensors, and the
TPMS will not function properly.
Some devices and transmitters may temporarily
interfere with the operation of the TPMS and
cause the low tire pressure warning light to illu-
minate. Some examples are:
– Facilities or electric devices using similar radio
frequencies are near the vehicle.
– If a transmitter set to similar frequencies is being used in or near the vehicle.
– If a computer (or similar equipment) or a DC/AC converter is being used in or near the
vehicle.

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 steering ma-
neuvers, because these driving practices could
cause you to lose control of your vehicle. As with
any vehicle, loss of control could result in a
collision with other vehicles or objects or
cause the vehicle to roll over, particularly if
the loss of control causes the vehicle to
slide sideways. Be attentive at all times, and

ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
●The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless
or dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remem-
ber that stopping distances on slippery
surfaces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel or snow covered roads, or if you
are using tire chains. Always maintain a
safe distance from the vehicle in front
of you. Ultimately, the driver is respon-
sible for safety.
● Tire type and condition of tires may also
affect braking effectiveness.
– When replacing tires, install the specified size of tires on all four
wheels. – When installing a spare tire, make
sure that it is the proper size and type
as specified on the Tire and Loading
Information label. See “Tire and
Loading Information label” in the
“Technical and consumer informa-
tion” section of this manual.
– For detailed information, see “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of
this manual.
The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on slip-
pery surfaces. When the ABS is operating the
SLIP indicator light in the instrument panel will
blink.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate to prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may hear
a “clunk” noise. This is normal and does not
indicate a malfunction. If the computer senses a
malfunction, it switches the ABS off and illumi-
nates the ABS warning light on the instrument
panel. The brake system then operates normally,
but without anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by a NISSAN dealer.
Starting and driving5-21

Normal operation
The ABS operates at speeds above4-6MPH(7
- 10 km/h) . The speed varies according to road
conditions.
When the ABS senses that 1 or more wheels are
close to locking up, the actuator rapidly applies
and releases hydraulic pressure. This action is
similar to pumping the brakes very quickly. You
may hear a noise from under the hood or feel a
vibration from the actuator when it is operating.
This is normal and indicates that the ABS is
operating properly. However, if theSLIPindica-
tor light blinks, the road conditions are hazardous
and extra care is required while driving. When accelerating on slippery surfaces the tire
may spin or slip. With the vehicle Traction Control
System (TCS) , sensors detect these movements
and control the braking and engine output to help
improve vehicle road traction.
● When the TCS is operating, the slip indica-
tor in the instrument panel blinks.
● If the slip indicator blinks, the vehicle is may
be under slippery conditions. Be sure to
drive carefully.
● If a malfunction occurs in the system, the
VDC warning light illuminates in the instru-
ment panel.
As long as the VDC warning light is on, the
traction control function is canceled. The vehicle
will behave like a vehicle without the system.
WARNING
● The Traction Control System is de-
signed to help maintain traction with
the road surface but does not prevent
accidents due to abrupt steering opera-
tion at high speeds or by careless or
dangerous driving techniques. Reduce
vehicle speed and be especially careful
when driving and cornering on slippery
surfaces and always drive carefully. ●
If brake related parts such as brake
pads, rotors and calipers are not stan-
dard equipment or are extremely dete-
riorated, the Traction Control System
may not operate properly and the VDC
warning light may come on.
● Do not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, bushings and
wheels are not standard equipment or
are extremely deteriorated, the Traction
Control System may not operate prop-
erly and the VDC warning light may
come on.
● If wheels or tires other than the recom-
mended ones are used, the Traction
Control System may not operate prop-
erly and the VDC warning light may
come on.
● The Traction Control System is not a
substitute for winter tires or tire chains
on a snow covered road.
