2011 NISSAN ALTIMA HYBRID coolant temperature

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.

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.

●Watch for slippery spots (glare ice) .
These may appear on an otherwise
clear road in shaded areas. If a patch of
ice is seen ahead, brake before reach-
ing it. Try not to brake while on the ice,
and avoid any sudden steering
maneuvers.
● Do not use the cruise control on slip-
pery roads.
● Snow can trap dangerous exhaust
gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.
ENGINE BLOCK HEATER (if so
equipped)
WARNING
● Do not use your engine block heater
with an ungrounded electrical system
or a 2-pronged adapter. You can be se-
riously injured by an electrical shock if
you use an ungrounded connection.
● Disconnect and properly store the en-
gine block heater cord before turning
the Hybrid System ON. Damage to the
cord could result in an electrical shock
and can cause serious injury. ●
Use a heavy-duty 3-wire, 3-pronged ex-
tension cord rated for at least 10 A. Plug
the extension cord into a Ground Fault
Interrupt (GFI) protected, grounded
110-VAC outlet. Failure to use the
proper extension cord or a grounded
outlet can result in a fire or electrical
shock and cause serious personal
injury.
Engine block heaters are available through
NISSAN dealers to assist in cold temperature
starting. The engine block heater should be used
when the outside temperature is 20° F (-7° C) or
lower.
To use the engine block heater: 1. Turn the Hybrid System OFF.
2. Open the hood and unwrap the engine block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged extension
cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected, grounded 110-
volt AC (VAC) outlet. 5. The engine block heater must be plugged in
for at least2-4hours, depending on outside
temperatures, to properly warm the engine
coolant. Use an appropriate timer to turn the
engine block heater on.
6. Before turning the Hybrid System ON, un- plug and properly store the cord to keep it
away from moving parts.

The inverter cooling system is filled at the factory
with a pre-diluted mixture of 50% Genuine
NISSAN Long Life Antifreeze/Coolant (blue) and
50% water to provide year-round anti-freeze and
coolant protection. The anti-freeze solution con-
tains rust and corrosion inhibitors. Additional in-
verter cooling system additives are not neces-
sary.
WARNING
●The temperature of the inverter rises to
140° F (60° C) . Never remove the coolant
reservoir cap when the engine and in-
verter are hot. Wait until the engine and
inverter cool down. Serious burns could
be caused by high pressure fluid escap-
ing from the reservoir.
● The inverter reservoir is equipped with a
pressure type cap. To prevent engine
and inverter damage, use only a genu-
ine NISSAN inverter reservoir cap.
CAUTION
When adding or replacing coolant, be sure
to use only a Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent.
Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-diluted to
provide antifreeze protection to -34° F
(-37° C) . If additional antifreeze protection
is needed due to weather where you oper-
ate your vehicle, add Genuine NISSAN
Long Life Antifreeze/Coolant (blue) . The
use of other types of coolant solutions
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent,
may damage the inverter cooling system.
CHECKING INVERTER COOLANT
LEVEL
Check the coolant level in the reservoir when
the engine and inverter are cold. If the cool-
ant level is below the MIN level
B, add coolant to
the MAX level
A.
If the inverter cooling system frequently
requires coolant, have it checked by a
NISSAN dealer.

CHANGING INVERTER COOLANT
A NISSAN dealer can change the inverter cool-
ant. The service procedure can be found in the
NISSAN Service Manual.
Improper servicing can result in inverter
overheating.
WARNING
●To avoid the danger of being scalded,
never change the coolant when the in-
verter is hot.
● Never remove the cap when the inverter
is hot. Serious burns could be caused
by high pressure fluid escaping from
the inverter coolant reservoir.
● Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
● Keep coolant out of the reach of chil-
dren and pets.
Engine coolant must be disposed of properly.
Check your local regulations.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and apply the parking brake.
2. Start the vehicle and let it idle until it reaches operating temperature.
3. Turn off the vehicle. Wait more than 10
minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick and wipe it clean. Re- insert it all the way. 5. Remove the dipstick again and check the oil
level. It should be between the H (High) and
L (Low) marksB. This is the normal oper-
ating oil level range. If the oil level is below
the L (Low) mark
A, remove the oil filler cap
and pour recommended oil through the
opening. Do not overfill
C.
6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the severity
of operating conditions.

●Be certain your rearview mirrors conform to
all federal, state or local regulations. If not,
install any mirrors required for towing before
driving the vehicle.
● Determine the overall height of the vehicle
and trailer so the required clearance is
known.
Trailer towing tips
In order to gain skill and an understanding of the
vehicle’s behavior, you should practice turning,
stopping and backing up in an area which is free
from traffic. Steering stability and braking perfor-
mance will be somewhat different than under
normal driving conditions.
● Always secure items in the trailer to prevent
load shift while driving.
● Lock the trailer hitch coupler with a pin or
lock to prevent the coupler from inadver-
tently becoming unlatched.
● Avoid abrupt starts, acceleration or stops.
● Avoid sharp turns or lane changes.
● Always drive your vehicle at a moderate
speed. ●
When backing up, hold the bottom of the
steering wheel with one hand. Move your
hand in the direction in which you want the
trailer to go. Make small corrections and
back up slowly. If possible, have someone
guide you when you are backing up.
Always block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so:CAUTION
If you move the shift selector to the P
(Park) position before blocking the
wheels and applying the parking brake,
transmission damage could occur.
1. Apply and hold the brake pedal.
2. Have someone place blocks on the downhill side of the vehicle and trailer wheels.
3. After the wheel blocks are in place, slowly release the brake pedal until the blocks ab-
sorb the vehicle load.
4. Apply the parking brake.
5. Shift the transmission into P (Park) .
6. Turn off the engine.
To drive away: 1. Start the vehicle. 2. Apply and hold the brake pedal.
3. Shift the transmission into gear.
4. Release the parking brake.
5. Drive slowly until the vehicle and trailer are
clear from the blocks.
6. Apply and hold the brake pedal.
7. Have someone retrieve and store the blocks. ● While going downhill, the weight of the
trailer pushing on the tow vehicle may de-
crease overall stability. Therefore, to main-
tain adequate control, reduce your speed
and shift to a lower gear. Avoid long or
repeated use of the brakes when descend-
ing a hill, as this reduces their effectiveness
and could cause overheating. Shifting to a
lower gear instead provides “engine brak-
ing” and reduces the need to brake as fre-
quently.
● If the engine coolant temperature rises to a
high temperature, refer to “If your vehicle
overheats” in the “In case of emergency”
section of this owner’s manual.
● Trailer towing requires more fuel than normal
circumstances.
● Avoid towing a trailer for your vehicle’s first
500 miles (805 km) .
