2011 NISSAN ALTIMA HYBRID check engine

Place the ignition switch in the ON position.
Depress the brake pedal and push the ignition
switch when the transmission is in the P (Park)
position to start the Hybrid System.
The READY light illuminates indicating that the
vehicle is ready to be driven. If the ambient tem-
perature is low, the READY may flash and may
take time until the READY light stays on. For
details, see “Starting the Hybrid System” in the
“Starting and driving” section of this manual.
As long as the READY light remains on you can
drive your vehicle using the traction motor even
though the gasoline engine may not be running.Drive your vehicle with smooth accelera-
tion and deceleration.
● While driving, energy is recovered through
the regenerative brake as the vehicle decel-
erates. However, for most efficient use, do
not accelerate or decelerate your vehicle
more than necessary.
● Avoid abrupt acceleration and deceleration.
● The power of the high voltage battery can be
checked on the high voltage battery status
meter. See “High voltage battery status me-
ter” in this section for details. Gradual or
non-abrupt acceleration and deceleration
will make more effective use of the traction
motor without having to use gasoline engine
power.
● When parking, be sure to place the shift
selector in the P (Park) position. While driv-
ing, place the shift selector in the D (Drive)
position.
● The Hybrid System recharges the high volt-
age battery as necessary. However, the Hy-
brid System can not charge the high voltage
battery when the transmission is in the N
(Neutral) position even if the engine is run-
ning. ●
If the high voltage battery becomes dis-
charged, the engine will run for a longer
period of time. Do not keep the transmission
in the N (Neutral) position with the system in
the ready mode.
NOTE:
The gasoline engine starts and stops auto-
matically. It may stop during low load driv-
ing, deceleration or when the vehicle is
stopped.
As long as the READY light remains on, you
can drive your vehicle using the traction
motor even with the gasoline engine
stopped.
The gasoline engine may not stop auto-
matically in the following conditions: ● During gasoline engine warm-up.
● During high voltage battery charging.
● During high or low high voltage battery
temperature.

WARNING/INDICATOR LIGHTS AND
AUDIBLE REMINDERS
Instruments and controls2-9

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

CAUTION
If the high temperature warning light illu-
minates while the engine is running, it
may indicate the engine temperature is
extremely high. Stop the vehicle safely as
soon as possible. If the vehicle is over-
heated, continuing vehicle operation may
seriously damage the engine. See “If your
vehicle overheats” in the “In case of emer-
gency” section.
High-voltage battery warninglight
This light may appear during the following condi-
tions:
● The high voltage battery voltage drops due
to the shift selector being left in “N”.
– The Hybrid System will work properly if the shift selector is placed in “P” and the
light goes off.
● The high voltage battery is discharged.
– If this light comes on when the READY light is on, stop your vehicle and contact
your NISSAN dealer
Hybrid system warning light
The hybrid system warning light comes on when:
● The amount of fuel in the tank is getting low.
● There is a problem with the traction motor or
other Hybrid System components.
If the fuel gauge indicates the fuel level is low,
refill the fuel tank immediately. See “Fuel gauge”
earlier in this section. After the fuel tank is filled,
the ignition switch is placed in the ON position,
and the Hybrid System is in the READY mode,
the hybrid system warning light should be off.
If the fuel gauge indicates a sufficient fuel level, or
if the hybrid system warning light comes on after
refilling the tank, there may be a problem with the
traction motor or other Hybrid System compo-
nents. Stop your vehicle immediately and contact
your NISSAN dealer.
Low tire pressure warning light
Your vehicle is equipped with a Tire Pressure
Monitoring System (TPMS) that monitors 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.
When the low tire pressure warning light
illuminates, you should stop and adjust the
tire pressure of all 4 tires to the recom-
mended COLD tire pressure shown on the
Tire and Loading Information label located
in the driver’s door opening. The low tire
pressure warning light does not automati-
cally turn off when the tire pressure is ad-
justed. After the tire is inflated to the rec-
ommended pressure, the vehicle 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.
For additional information, see “Tire Pressure
Monitoring System (TPMS)” in the “Starting and
driving” section and in the “In case of emergency”
section.
Instruments and controls2-13

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.

Indicators for maintenance
1. Engine oil replacement indicatorThis indicator appears when the customer
set distance comes for changing the engine
oil. You can set or reset the distance for
changing the engine oil. See “Maintenance
mode” earlier in this section.
2. Oil filter replacement indicator This indicator appears when the customer
set distance comes for replacing the oil filter.
You can set or reset the distance for replac-
ing the oil filter. See “Maintenance mode”
earlier in this section.
3. Tire replacement indicator This indicator appears when the customer
set distance comes for replacing tires. You
can set or reset the distance for replacing
tires. See “Maintenance mode” earlier in this
section.
WARNING
The tire replacement indicator is not a
substitute for regular tire checks, includ-
ing tire pressure checks. See “Changing
Wheels and Tires” in “Maintenance & Do-
It-Yourself” section. Many factors includ-
ing tire inflation, alignment, driving habits
and road conditions affect tire wear and
when tires should be replaced. Setting the
tire replacement indicator for a certain
driving distance does not mean your tires
will last that long. Use the tire replace-
ment indicator as a guide only and always
perform regular tire checks. Failure to per-
form regular tire checks, including tire
pressure checks could result in tire fail-
ure. Serious vehicle damage could occur
and may lead to a collision, which could
result in serious personal injury or death. 4. “OTHER” indicator
This indicator appears when the customer
set distance comes for checking or replac-
ing maintenance items other than the engine
oil, oil filter and tires. Other maintenance
items can include such things as air filter or
tire rotation. You can set or reset the dis-
tance for checking or replacing the items.
See “Maintenance mode” earlier in this sec-
tion. For scheduled maintenance items and
intervals, see your “NISSAN Service and
Maintenance Guide.”
