2010 NISSAN ALTIMA engine

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.

RADIO
With the ignition placed in the ACC or ON posi-
tion, press the PWR (power)/VOL (volume) knob
to turn the radio on. If you listen to the radio with
the engine not running, the ignition should be
placed in the ACC position.
Radio reception is affected by station signal
strength, distance from radio transmitter, build-
ings, bridges, mountains and other external influ-
ences. Intermittent changes in reception quality
normally are caused by these external influences.
Using a cellular phone in or near the ve-
hicle may influence radio reception quality.
Radio reception
Your NISSAN radio system is equipped with
state-of-the-art electronic circuits to enhance ra-
dio reception. These circuits are designed to
extend reception range, and to enhance the qual-
ity of that reception.
However, there are some general characteristics
of both FM and AM radio signals that can affect
radio reception quality in a moving vehicle, even
when the finest equipment is used. These char-
acteristics are completely normal in a given re-
ception area and do not indicate any malfunction
in your NISSAN radio system.Reception conditions will constantly change be-
cause of vehicle movement. Buildings, terrain,
signal distance and interference from other ve-
hicles can work against ideal reception. De-
scribed below are some of the factors that can
affect your radio reception.
Some cellular phones or other devices may
cause interference or a buzzing noise to come
from the audio system speakers. Storing the de-
vice in a different location may reduce or elimi-
nate the noise.
FM RADIO RECEPTION
Range: FM range is normally limited to 25 – 30 mi
(40 – 48 km) , with monaural (single channel) FM
having slightly more range than stereo FM. Exter-
nal influences may sometimes interfere with FM
station reception even if the FM station is within
25 mi (40 km) . The strength of the FM signal is
directly related to the distance between the
transmitter and receiver. FM signals follow a line-
of-sight path, exhibiting many of the same char-
acteristics as light. For example, they will reflect
off objects.
Fade and drift: As your vehicle moves away from
a station transmitter, the signals will tend to fade
and/or drift.
Static and flutter: During signal interference from
buildings, large hills or due to antenna position
(usually in conjunction with increased distance
from the station transmitter) , static or flutter can
be heard. This can be reduced by adjusting the
treble control to reduce treble response.
Multipath reception: Because of the reflective
characteristics of FM signals, direct and reflected
signals reach the receiver at the same time. The
signals may cancel each other, resulting in mo-
mentary flutter or loss of sound.
AM RADIO RECEPTION
AM signals, because of their low frequency, can
bend around objects and skip along the ground.
In addition, the signals can be bounced off the
ionosphere and bent back to earth. Because of
these characteristics, AM signals are also sub-
ject to interference as they travel from transmitter
to receiver.
Fading: Occurs while the vehicle is passing
through freeway underpasses or in areas with
many tall buildings. It can also occur for several
seconds during ionospheric turbulence even in
areas where no obstacles exist.
Static: Caused by thunderstorms, electrical
power lines, electric signs and even traffic lights.

PLAYER OPERATION (models with
Navigation System)
Precautions
Start the engine when using the DVD entertain-
ment system.
Movies will not be shown on the front display
while the vehicle is in any drive position to reduce
driver distraction. Audio is available when a movie
is played. To view movies on the front display,
stop the vehicle in a safe location, move the shift
selector to the P (Park) position and apply the
parking brake.

CAUTION
●Do not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants.
● Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly by a NISSAN dealer.
● Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
● Do not race the engine while warming it
up.
● Do not push or tow your vehicle to start
the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided) ,
should be checked monthly when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label, located in the
driver’s door opening.
(If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire infla-
tion pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly
under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check all 4 tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping
ability. Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction indicator is
illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons,
including the installation of replacement or alter-
nate tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replac-
ing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.

WARNING
Do not operate the push-button ignition
switch while driving the vehicle except in
an emergency. (The engine will stop when
the ignition switch is pushed 3 consecu-
tive times in quick succession or the igni-
tion 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 de-
pressing the brake pedal (CVT) or the clutch
pedal (MT) , the ignition switch position will illu-
minate 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 return to the
LOCK position when any door is either opened or
closed with the switch in the OFF position. The ignition lock is designed so that the ignition
switch position cannot be switched to OFF until
the shift selector is moved to the P (Park) position
(CVT) or N (Neutral) position (MT) .
When the ignition switch cannot be pushed to-
ward the OFF position, proceed as follows:
1. Move the shift selector into the P (Park) position (CVT) or N (Neutral) position (MT) .
2. Push the ignition switch. The ignition switch position will change to the ON position.
3. Push the ignition switch again to the OFF position.
The shift selector 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 push-button ignition switch cannot be
moved from the LOCK position.
Some indicators and warnings for operation are
displayed on the vehicle information display. See
“Vehicle information display” in the “Instruments
and controls” section.

PUSH-BUTTON IGNITION SWITCH
POSITIONS
LOCK (Normal parking position):
The ignition switch can only be locked in this
position.
The ignition switch will be unlocked when it is
pushed to the ACC position while carrying the
Intelligent Key or with the Intelligent Key inserted
in the port.
The ignition switch will lock when any door is
opened or closed with the ignition switched off.
OFF:
The ignition switch is in the OFF position when
the engine is turned off using the ignition switch.
No lights will illuminate on the ignition switch.
ACC (Accessories):
This position activates electrical accessories,
such as the radio, when the engine is not running.
ACC has a battery saver feature that will turn the
ignition switch to the OFF position after 1 hour
under the following conditions:● all doors are closed.
● shift selector is in P (Park) . The battery saver feature will be cancelled if any
of the following occur:
● any door is opened.
● shift selector is moved out of the P (Park) .
● ignition switch changes position.
ON (Normal operating position):
This position turns on the ignition system and
electrical accessories.

1. Apply the parking brake.
2.Continuously Variable Transmission
(CVT) model:
Move the shift selector to P (Park) or N
(Neutral) . P (Park) is recommended.
The starter is designed not to operate if
the shift selector is in any of the driving
positions.
Manual transmission:
Move the shift selector to N (Neutral) . De-
press the clutch pedal to the floor.
The starter is designed not to operate
unless the clutch pedal is fully de-
pressed.
3. Push the ignition switch to the ON position. Depress the brake pedal and the clutch
pedal (if so equipped) and push the ignition
switch to start the engine.
To start the engine immediately, push and
release the ignition switch while depressing
the brake pedal with the ignition switch in
any position. ●
If the engine is very hard to start in ex-
tremely cold weather or when restarting,
depress the accelerator pedal a little (ap-
proximately 1/3 to the floor) and while
holding, crank the engine. Release the
accelerator pedal when the engine starts.
● If the engine is very hard to start because
it is flooded, depress the accelerator
pedal all the way to the floor and hold it.
Push the ignition switch to the ON posi-
tion to start cranking the engine. After 5 or
6 seconds, stop cranking by pushing the
ignition switch to LOCK. After cranking
the engine, release the accelerator pedal.
Crank the engine with your foot off the
accelerator pedal by depressing the
brake pedal and pushing the push-button
ignition switch to start the engine. If the
engine starts, but fails to run, repeat the
above procedure.

The CVT can operate in two different automatic
drive modes:● D (Drive) mode - Move the shift selector to D
(Drive) , the transmission is in the normal
forward automatic driving mode. The posi-
tion indicator in the meter shows a “D”. The
D (Drive) mode does not produce a gear
change sensation like a traditional automatic
transmission.
● Ds (Drive Sport) mode - Move the shift se-
lector over from D (Drive) to the left into the
manual shift gate. The position indicator in
the meter shows a “Ds”. In Ds (Drive Sport)
mode, transmission operation changes to
Sporty” driving shift operation, creating a
more aggressive acceleration feeling than
the D (Drive) mode and a gear change sen-
sation when the driver accelerates quickly.
When the driver selects M (Manual) mode
ratio with shift selector during Ds (Drive
Sport) mode operation, the driver must move
the shift selector from Ds mode to D mode
and back again to re-select Ds (Drive Sport)
mode.
● To cancel the Ds mode, return the shift se-
lector to the D (Drive) position. The trans-
mission returns to the automatic drive mode. The CVT can operate in a manual drive mode:
● M (Manual) mode - With the shift selector in
the manual shift gate Ds (Drive Sport) mode,
M (Manual) mode can be selected by mov-
ing the shift selector up (+) or down (–) . In M
mode, the transmission will produce notice-
able upshifts and downshifts. The position
indicator in the meter shows a “M”.
Follow these procedures for maximum vehicle
performance and driving enjoyment.
NOTE:
Engine power may be automatically re-
duced to protect the CVT if the engine
speed increases quickly when driving on
slippery roads or while being tested on
some dynamometers.
Starting the vehicle
1. After starting the engine, fully depress the foot brake pedal before moving the shift
selector out of the P (Park) position.
2. Keep the foot brake pedal depressed and move the shift selector into a driving gear.
3. Release the foot brake, then gradually start the vehicle in motion.
4. Stop the vehicle completely before shifting the shift selector to the P (Park) position. The CVT is designed so the foot brake
pedal MUST be depressed before shifting
from P (Park) to any drive position while
the ignition switch is in the ON position.
The shift selector cannot be moved out of P
(Park) and into any of the other gear posi-
tions if the ignition switch is pushed to the
LOCK or ACC position.
