engine INFINITI EX 2011 Workshop Manual

WARNING
●Do not leave children or adults who would
normally require the support of others alone
in your vehicle. Pets should not be left alone
either. They could accidentally injure them-
selves or others through inadvertent opera-
tion 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.
● Properly secure all cargo to help prevent it
from sliding or shifting. Do not place cargo
higher than the seatbacks. In a sudden stop
or collision, unsecured cargo could cause
personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
● Do not breathe exhaust gases; they contain
colorless and odorless carbon monoxide.
Carbon monoxide is dangerous. It can cause
unconsciousness or death.
● If you suspect that exhaust fumes are enter-
ing the vehicle, drive with all windows 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 run-
ning for any extended length of time.
● Keep the lift gate closed while driving, oth-
erwise exhaust gases could be drawn into
the passenger compartment. If you must
drive with the lift gate open, follow these
precautions:
1. Open all the windows.
2. Set the
air recirculation to off and
the fan control to high to circulate the air.
● If electrical wiring or other cable connec-
tions must pass to a trailer through the seal
on the lift gate or the body, follow the manu-
facturer’s recommendation to prevent car-
bon monoxide entry into the vehicle.
● The exhaust system and body should be in-
spected by a qualified mechanic whenever:
– The vehicle is raised for service.
– You suspect that exhaust fumes are en- tering into the passenger compartment.
– You notice a change in the sound of the exhaust system. – You have had an accident involving dam-
age to the exhaust system, underbody, 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 system are
very hot. Keep people, animals or flammable
materials away from the exhaust system
components.
● Do not stop or park the vehicle over flam-
mable materials such as dry grass, waste
paper or rags. They may ignite and cause a
fire.
CAUTION
● Do not use leaded gasoline. Deposits from
leaded gasoline seriously reduce the three-
way catalyst’s ability to help reduce exhaust
pollutants.
PRECAUTIONS WHEN STARTING AND
DRIVING
5-2Starting and driving

●Keep your engine tuned up. Malfunctions in
the ignition, fuel injection, or electrical sys-
tems can cause overrich fuel flow into the
three-way catalyst, causing it to overheat.
Do not keep driving if the engine misfires, or
if noticeable loss of performance or other
unusual operating conditions are detected.
Have the vehicle inspected promptly by an
INFINITI retailer.
● 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
inflated 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 pres-
sure 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 pres-
sure. Driving on a significantly under-inflated
tire causes the tire to overheat 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
malfunction 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 continu-
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not beable to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing 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.
Additional information
●
The TPMS does not monitor the tire pressure
of the spare tire.
● The TPMS will activate only when the vehicle
is driven at speeds above 16 MPH (25 km/h).
Also, this system may not detect a sudden
drop in tire pressure (for example a flat tire
while driving).
● The low tire pressure warning light does not
automatically turn off when the tire pressure
is adjusted. After the tire is inflated to the
recommended 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 pressure
gauge to check the tire pressure.
● The CHECK TIRE PRESSURE warning appears
in the vehicle information display when the
low tire pressure warning light is illuminated

gency” section of this Owner’s Manual.
DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of alcohol or
drugs. Alcohol in the bloodstream reduces co-
ordination, delays reaction time and impairs
judgement. Driving after drinking alcohol in-
creases the likelihood of being involved in an
accident injuring yourself and others. Addition-
ally, if you are injured in an accident, alcohol
can increase the severity of the injury.
INFINITI is committed to safe driving. However,
you must choose not to drive under the influ-
ence of alcohol. Every year thousands of people
are injured or killed in alcohol-related acci-
dents. Although 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 alco-
hol. Remember, drinking and driving don’t mix! And
that is true for drugs, too (over-the-counter,
prescription, and illegal drugs). Don’t drive if
your ability to operate your vehicle is impaired
by alcohol, drugs, or some other physical con-
dition.
ALL-WHEEL DRIVE (AWD) DRIVING
SAFETY PRECAUTIONS (for AWD
models)
WARNING
●
Do not drive beyond the performance capa-
bility of the tires, even with AWD engaged.
Accelerating quickly, sharp steering maneu-
vers or sudden braking may cause loss of
control.
● Always use tires of the same type, size,
brand, construction (bias, bias-belted or ra-
dial), and tread pattern on all four wheels.
Install tire chains on the rear wheels when
driving on slippery roads and drive carefully.
● This vehicle is not designed for offroad
(rough road) use. Do not drive on sandy or
muddy roads that tires may get stuck in. ●
For AWD equipped vehicles, do not attempt
to raise two wheels off the ground and shift
the transmission to any D (Drive) or R (Re-
verse) position with the engine running. Do-
ing so may result in drivetrain damage or
unexpected vehicle movement which could
result in serious vehicle damage or personal
injury.
● Do not attempt to test an AWD equipped ve-
hicle on a 2-wheel dynamometer, (such as
the dynamometers used by some states for
emissions testing), or similar equipment
even if the other two wheels are raised off
the ground. Make sure you inform test facil-
ity personnel that your vehicle is equipped
with AWD before it is placed on a dynamom-
eter. Using the wrong test equipment may
result in drivetrain damage or unexpected
vehicle movement which could result in seri-
ous vehicle damage or personal injury.
● When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.

AUTOMATIC TRANSMISSION
7 speed automatic transmission
The automatic transmission in your vehicle is
electronically controlled by a transmission con-
trol module to produce maximum efficiency and
smooth operation.
Shown on the following pages are the recom-
mended operating procedures for this transmis-
sion. Follow these procedures for maximum
vehicle performance and driving enjoyment.
Starting the vehicle
After starting the engine, fully depress the foot
brake pedal and push the selector lever button
before shifting the selector lever to the R (Re-
verse), N (Neutral), D (Drive), DS (Drive Sport) or
Manual shift mode position. Be sure the vehicle
is fully stopped before attempting to shift the
selector lever.
This automatic transmission model is designed
so that the foot brake pedal must be depressed
before shifting from P (Park) to any drive posi-
tion while the ignition switch position is ON.
The selector lever cannot be moved out of the P
(Park) position and into any of the other gear
positions if the ignition switch is pushed to the
LOCK, OFF or ACC position.
1. Keep the foot brake pedal depressed and
push the selector lever button to shift into
a driving gear.
2. Release the parking brake and foot brake, then gradually start the vehicle in motion.
WARNING
●Do not depress the accelerator pedal while
shifting from P (Park) or N (Neutral) to R (Re-
verse), D (Drive), DS (Drive Sport) or manual
shift mode. Always 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 cau-
tion when shifting into a forward or reverse
gear before the engine has warmed up.
● Never shift to P (Park) or R (Reverse) while
vehicle is moving forward. Never shift to P
(Park), D (Drive) or DS (Drive Sport) while
vehicle is moving rearward. Failure to do so
could cause you to lose control and have an
accident.
DRIVING THE VEHICLE
5-12Starting and driving

●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 addition, 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 depressing
the accelerator pedal. The foot brake should
be used for this purpose.
● Do not downshift abruptly on slippery roads.
This may cause a loss of control.
Shifting
To move the selector lever,
: Push the button while depressing the
brake pedal,
: Push the button,
: Just move the selector lever.
After starting the engine, fully depress the
brake pedal and shift the selector lever from P
(Park) to R (Reverse), N (Neutral), D (Drive), DS
(Drive Sport) or Manual shift mode position. Push the button to shift into P (Park) or R
(Reverse). All other positions can be selected
without pushing the button.
WARNING
Apply the parking brake if the selector lever 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.
CAUTION
Make sure the vehicle is completely stopped
and the transmission is in the P (Park) position.
P (Park) position :
Use this selector position when the vehicle is
parked or when starting the engine. Make sure
the vehicle is completely stopped. The brake
pedal must be depressed and the selector lever
button pushed in to move the selector lever from
the N (Neutral) position or any drive position to

CAUTION
Use this position only when the vehicle is com-
pletely stopped.
R (Reverse) :
Use this position to back up. Always be sure the
vehicle is completely stopped before selecting
the R (Reverse) position. The brake pedal must
be depressed and the selector lever button
pushed in to move the selector lever from the P
(Park) position, the N (Neutral) position or any
drive position to the R (Reverse) position.
N (Neutral) :
Neither forward nor reverse gear is engaged.
The engine can be started in this position. You
may shift to the N (Neutral) position and restart
a stalled engine while the vehicle is moving.
D (Drive) :
Use this position for all normal forward driving.
DS (Drive Sport) mode
Move the selector lever from D (Drive) to the left
into the manual shift gate. The transmission
position indicator in the meter shows “DS”.
In the DS (Drive Sport) mode, the transmission
changes to the “sporty” driving shift operation, creating a more aggressive acceleration feeling
than the D (Drive) mode and providing a gear
change sensation when the driver accelerates
quickly.
When the driver selects the manual shift mode
using the selector lever during the DS (Drive
Sport) mode operation, the driver must move
the selector lever from DS (Drive Sport) to D
(Drive) and back again to re-select the DS (Drive
Sport) mode.
Manual shift mode
When the selector lever is in the DS (Drive
Sport) position, the transmission is ready for
the manual shift mode. Shift ranges can be
selected manually by moving the selector lever
up or down.
When shifting up, move the selector lever to the
+ (up) side. The transmission shifts to the
higher range.
When shifting down, move the selector lever to
the
(down) side. The transmission shifts to
the lower range.
When canceling the manual shift mode, return
the selector lever to the D (Drive) position. The
transmission returns to the normal driving
mode. In the manual shift mode, the shift range is
displayed on the position indicator in the meter.
Shift ranges up or down one by one as follows:
M1

M7 (7th) :
Use these positions for all normal forward
driving at highway speeds.
M6 (6th) andM5 (5th) :
Use this position when driving up long slopes,
or for engine braking when driving down long
slopes.
M4 (4th),M3 (3rd) andM2 (2nd) :
Use these positions for hill climbing or engine
braking on downhill grades.
M1 (1st) :
Use this position when climbing steep hills
slowly or driving slowly through deep snow, or
for maximum engine braking on steep downhill
grades.
● Remember not to drive at high speeds for
extended periods of time in lower than 7th
gear. This reduces fuel economy.

LANE DEPARTURE WARNING (LDW)
SYSTEM
Precautions on LDW system
WARNING
●This system is only a warning device to in-
form the driver of a potential unintended
lane departure. It will not steer the vehicle or
prevent loss of control. It is the driver’s re-
sponsibility to stay alert, drive safely, keep
the vehicle in the traveling lane, and be in
control of the vehicle at all times.
● The system will not operate at speeds below
approximately 45 MPH (70 km/h) or if it can-
not detect lane markers.
● If the LDW system malfunctions, it will can-
cel automatically, and the lane departure
warning light (orange) will illuminate.
● If the lane departure warning light (orange)
illuminates, pull off the road to a safe loca-
tion and stop the vehicle. Turn the engine off
and restart the engine. If the lane departure
warning light (orange) continues to illumi-
nate, have the system checked by an INFINITI
retailer. ●
Excessive noise will interfere with the warn-
ing chime sound, and the chime may not be
heard.
The system may not function properly under the
following conditions:
● On roads where there are multiple parallel
lane markers; lane markers that are faded or
not painted clearly; yellow painted lane
markers; non-standard lane markers; or lane
markers covered with water, dirt, snow, etc.
● On roads where the discontinued lane mark-
ers are still detectable.
● On roads where there are sharp curves.
● On roads where there are sharply contrast-
ing objects, such as shadows, snow, water,
wheel ruts, seams or lines remaining after
road repairs. (The LDW system could detect
these items as lane markers.)
● On roads where the traveling lane merges or
separates.
● When the vehicle’s traveling direction does
not align with the lane marker.
● When traveling close to the vehicle in front
of you, which obstructs the lane camera unit
detection range. ●
When rain, snow or dirt adheres to the
windshield in front of the lane camera unit.
● When the headlights are not bright due to
dirt on the lens or if the aiming is not
adjusted properly.
● When strong light enters the lane camera
unit. (For example, the light directly shines
on the front of the vehicle at sunrise or
sunset.)
● When a sudden change in brightness occurs.
(For example, when the vehicle enters or
exits a tunnel or under a bridge.)
