engine NISSAN ALTIMA COUPE 2012 D32 / 4.G Workshop Manual

WARNING
●Do not leave children or adults who
would normally require the assistance
of others alone in your vehicle. Pets
should also not be left alone. They
could accidentally injure themselves or
others through inadvertent operation of
the vehicle. Also, on hot, sunny days,
temperatures in a closed vehicle could
quickly become high enough to cause
severe or possibly fatal injuries to
people or animals.
● Closely supervise children when they
are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously in-
jured. Keep the car locked, with the rear
seatback and trunk lid securely latched
when not in use, and prevent children’s
access to car keys.
EXHAUST GAS (carbon monoxide)
WARNING
● Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is danger-
ous. It can cause unconsciousness or
death. ●
If you suspect that exhaust fumes are
entering the vehicle, drive with all win-
dows fully open, and have the vehicle
inspected immediately.
● Do not run the engine in closed spaces
such as a garage.
● Do not park the vehicle with the engine
running for any extended length of time.
● Keep the rear vent windows, lift gates,
doors and trunk lids (if so equipped)
closed while driving, otherwise exhaust
gases could be drawn into the passen-
ger compartment. If you must drive with
one of these open, follow these
precautions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial to
high to circulate the air.
● If electrical wiring or other cable con-
nections must pass to a trailer through
the seal on the trunk lid or the body,
follow the manufacturer’s recommen-
dation to prevent carbon monoxide en-
try into the vehicle. ●
The exhaust system and body should be
inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involving damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
WARNING
●The exhaust gas and the exhaust sys-
tem are very hot. Keep people, animals
or flammable materials away from the
exhaust system components.
● Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
PRECAUTIONS WHEN STARTING
AND DRIVING
5-2Starting and driving

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. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation 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 your 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.

3. When appropriate, slowly release the accel-erator pedal to gradually slow the vehicle.
4. Gradually steer the vehicle to a safe location off the road and away from traffic if possible.
5. Lightly apply the brake pedal to gradually stop the vehicle.
6. Turn on the hazard warning flashers and either contact a roadside emergency service
to change the tire or see “Changing a flat
tire” in the “In case of emergency” section of
this manual.
DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of alcohol
or drugs. Alcohol in the bloodstream re-
duces coordination, delays reaction time
and impairs judgement. Driving after
drinking alcohol increases the likelihood
of being involved in an accident injuring
yourself and others. Additionally, if you
are injured in an accident, alcohol can
increase the severity of the injury. NISSAN is committed to safe driving. However,
you must choose not to drive under the influence
of alcohol. Every year thousands of people are
injured or killed in alcohol-related accidents. Al-
though the local laws vary on what is considered
to be legally intoxicated, the fact is that alcohol
affects all people differently and most people
underestimate the effects of alcohol.
Remember, drinking and driving don’t mix! And
that is true for drugs, too (over-the-counter, pre-
scription, and illegal drugs) . Don’t drive if your
ability to operate your vehicle is impaired by alco-
hol, drugs, or some other physical condition.
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.
PUSH-BUTTON IGNITION SWITCH
Starting and driving5-7

When the ignition switch is pushed without de-
pressing the brake pedal (CVT) or the clutch
pedal (M/T) , 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 (M/T) .
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 (M/T) .
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.

NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer system will not
allow the engine to start without the use of the
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-
cedure:
1. Leave the ignition switch 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. ●
Make sure the area around the vehicle is
clear.
● Check fluid levels such as engine oil, cool-
ant, brake fluid, and windshield-washer fluid
as frequently as possible, or at least when-
ever you refuel.
● Check that all windows and lights are clean.
● Visually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
● Lock all doors.
● Position seat and adjust head restraints.
● Adjust inside and outside mirrors.
● Fasten seat belts and ask all passengers to
do likewise.
● Check the operation of warning lights when
the ignition switch is pushed to the ON
position. See “Warning/indicator lights and
audible reminders” in the “Instruments and
controls” section of this manual.
BEFORE STARTING THE ENGINE
5-10Starting and driving

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 (M/T) model:
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.CAUTION
Do not operate the starter for more than
15 seconds at a time. If the engine does
not start, push the ignition switch to the
OFF position and wait 10 seconds before
cranking again, otherwise the starter
could be damaged.
4. Warm-up
Allow the engine to idle for at least 30 sec-
onds after starting. Do not race the engine
while warming it up. Drive at moderate
speed for a short distance first, especially in
cold weather. In cold weather, keep the en-
gine running for a minimum of2-3minutes
before shutting it off. Starting and stopping
the engine over a short period of time may
make the vehicle more difficult to start.
5. To stop the engine, shift the shift selector to the P (Park) position (CVT) or to N (Neutral)
and apply the parking brake (M/T) and push
the ignition switch to the OFF position.

CONTINUOUSLY VARIABLE
TRANSMISSION (CVT) (if so
equipped)
WARNING
●Do not depress the accelerator pedal
while shifting from P (Park) or N (Neu-
tral) to R (Reverse) , D (Drive) , Ds (Drive
Sport) or (M) Manual shift mode. Al-
ways depress the brake pedal until
shifting is completed. Failure to do so
could cause you to lose control and
have an accident.
● Cold engine idle speed is high, so use
caution when shifting into a forward or
reverse gear before the engine has
warmed up.
● Do not downshift abruptly on slippery
roads. This may cause a loss of control.
● Never shift to P (Park) or R (Reverse)
while the vehicle is moving. This could
cause an accident.
● Except in an emergency, do not shift to
the N (Neutral) position while driving.
Doing so can cause a loss of engine
braking which may result in a collision,
serious personal injury or death. In ad-
dition, coasting with the transmission
in the N (Neutral) position may cause
serious damage to the transmission.
CAUTION
When stopping the vehicle on an uphill
grade, do not hold the vehicle by depress-
ing the accelerator pedal. The foot brake
should be used for this purpose.
The CVT in your vehicle is electronically con-
trolled to produce maximum power and smooth
operation.
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.
WSD0247
DRIVING THE VEHICLE
5-12Starting and driving

●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 position. To move the shift selector:
Press the button while depressing the
brake pedal
Press the button to shift
Shift without pressing button

WARNING
Apply the parking brake if the shift selec-
tor is in any position while the engine is
not running. Failure to do so could cause
the vehicle to move unexpectedly or roll
away and result in serious personal injury
or property damage.
P (Park):
CAUTION
To prevent transmission damage, use the
P (Park) or R (Reverse) position only when
the vehicle is completely stopped.
Use the P (Park) shift selector position when the
vehicle is parked or when starting the engine.
Make sure the vehicle is completely stopped.
The brake pedal should be depressed to
move the shift selector from N (Neutral) or
any drive position to P (Park) . Apply the
parking brake. When parking on a hill, apply the
parking brake first, then move the shift selector
into the P (Park) position. R (Reverse):
CAUTION
To prevent transmission damage, use the
P (Park) or R (Reverse) position only when
the vehicle is completely stopped.
Use the R (Reverse) position to back up. Make
sure the vehicle is completely stopped before
selecting the R (Reverse) position. The brake
pedal must be depressed to move the shift
selector from P (Park) , N (Neutral) or any
drive position to R (Reverse) .
N (Neutral):
Neither forward nor reverse gear is engaged. The
engine can be started in this position. You may
shift to N (Neutral) and restart a stalled engine
while the vehicle is moving.
D (Drive):
Use this position for all normal forward driving. DS (Drive Sport):
When the shift selector is shifted from the D
(Drive) position to the manual shift gate, the
transmission enters the DS (Drive Sport) mode.
Moving the shift selector to the DS (Drive Sport)
position allows you to enjoy “sporty” driving shift
operation on a winding road and feel smooth
acceleration or deceleration on a hilly road by
moving in a lower gear automatically. When can-
celing the DS mode, return the shift selector to
the D (Drive) position. The transmission returns to
the normal driving mode.
