engine INFINITI JX 2013 Repair Manual

●Do not drive across steep slopes. In-
stead drive either straight up or straight
down the slopes. Off-road vehicles can
tip over sideways much more easily
than they can forward or backward.
● Many hills are too steep for any vehicle.
If you drive up them, you may stall. If
you drive down them, you may not be
able to control your speed. If you drive
across them, you may roll over.
● Do not shift gears while driving on
downhill grades as this could cause
loss of control of the vehicle.
● Stay alert when driving to the top of a
hill. At the top there could be a drop-off
or other hazard that could cause an
accident.
● If your engine stalls or you cannot make
it to the top of a steep hill, never at-
tempt to turn around. Your vehicle
could tip or roll over. Always back
straight down in R (Reverse) gear and
apply brakes to control your speed.
● Heavy braking going down a hill could
cause your brakes to overheat and fade,
resulting in loss of control and an acci-
dent. Apply brakes lightly and use a low
gear to control your speed. ●
Unsecured cargo can be thrown around
when driving over rough terrain. Prop-
erly secure all cargo so it will not be
thrown forward and cause injury to you
or your passengers.
● Secure heavy loads in the cargo area as
far forward and as low as possible. Do
not equip the vehicle with tires larger
than specified in this manual. This
could cause your vehicle to roll over.
● Do not grip the inside or spokes of the
steering wheel when driving off-road.
The steering wheel could move sud-
denly and injure your hands. Instead
drive with your fingers and thumbs on
the outside of the rim.
● Before operating the vehicle, ensure
that the driver and all passengers have
their seat belts fastened.
● Always drive with the floor mats in
place as the floor may become hot.
● Lower your speed when encountering
strong crosswinds. With a higher center
of gravity, your INFINITI is more af-
fected by strong side winds. Slower
speeds ensure better vehicle control. ●
Do not drive beyond the performance
capability of the tires, even with AWD
engaged.
● For AWD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to
any drive or reverse position with the
engine running. Doing so may result in
drivetrain damage or unexpected ve-
hicle movement which could result in
serious vehicle damage or personal
injury.
● Do not attempt to test a AWD equipped
vehicle 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 facility personnel
that your vehicle is equipped with AWD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or per-
sonal injury.
● When a wheel is off the ground due to
an unlevel surface, do not spin the
wheel excessively.
Starting and driving5-9

●Accelerating quickly, sharp steering
maneuvers or sudden braking may
cause loss of control.
● If at all possible, avoid sharp turning
maneuvers, particularly at high speeds.
Your INFINITI vehicle has a higher cen-
ter of gravity than a passenger car. The
vehicle is not designed for cornering at
the same speeds as passenger cars.
Failure to operate this vehicle correctly
could result in loss of control and/or a
rollover accident.
● Always use tires of the same type, size,
brand, construction (bias, bias-belted,
or radial) , and tread pattern on all four
wheels. Install tire chains on the front
wheels when driving on slippery roads
and drive carefully.
● Be sure to check the brakes immedi-
ately after driving in mud or water. See
“Brake system” later in this section for
“Wet brakes”.
● Avoid parking your vehicle on steep
hills. If you get out of the vehicle and it
rolls forward, backward or sideways,
you could be injured. ●
Whenever you drive off-road through
sand, mud or water as deep as the
wheel hub, more frequent maintenance
may be required. See “Periodic mainte-
nance” in the “INFINITI Service and
Maintenance Guide.”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.

INFINITI VEHICLE IMMOBILIZER
SYSTEM
The INFINITI Vehicle Immobilizer System will not
allow the engine to start without the use of the
registered key.
If the engine fails to start using the registered key,
it may be due to interference caused by another
registered key, an automated toll road device or
automated payment device on the key ring. Re-
start the engine using the following procedures:
1. Leave the ignition switch in the ON position for approximately 5 seconds.
2. Turn the ignition switch to the OFF or LOCK position and wait approximately 5 seconds.
3. Repeat step 1 and 2 again.
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, INFINITI rec-
ommends placing the registered key on a sepa-
rate key ring to avoid interference from other
devices.

CONTINUOUSLY VARIABLE
TRANSMISSION (CVT)
The Continuously Variable Transmission (CVT) in
your vehicle is electronically controlled to pro-
duce maximum power and smooth operation.
The recommended operating procedures for this
transmission are shown on the following pages.
Follow these procedures for maximum vehicle
performance and driving enjoyment.
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.
This CVT is designed so that the foot
brake pedal must be depressed before
shifting from P (Park) to any driving
position while the ignition switch is in
the ON position.
The shift selector cannot be moved out
of the P (Park) position and into any of
the other positions if the ignition
switch is placed in the LOCK, OFF or
ACC position. 2. Keep the foot brake pedal depressed and
move the shift selector to a driving position.
3. Release the parking brake and foot brake pedal, and then gradually start the vehicle in
motion.
WARNING
●Do not depress the accelerator pedal
while shifting from P (Park) or N (Neu-
tral) to R (Reverse) or D (Drive) position.
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
caution 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. Failure to do so
could cause you to lose control and
have an accident.
DRIVING THE VEHICLE
Starting and driving5-15

CAUTION
●When stopping the vehicle on an uphill
grade, do not hold the vehicle by de-
pressing 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.
● Except in an emergency, do not shift to
the N (Neutral) position while driving.
Coasting with the transmission in the N
(Neutral) position may cause serious
damage to the transmission.

and move the shift selector from the P (Park)
position to any of the desired shift positions.
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.
CAUTION
Use the P (Park) or R (Reverse) position
only when the vehicle is completely
stopped.
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 must be depressed and
the shift selector button pushed in 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.
LSD2019

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 and the shift se-
lector button pushed in 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.
Manual shift mode
When the shift selector is in the manual shift gate,
the transmission is ready for the manual shift
mode. Shift ranges can be selected manually by
moving the shift selector up or down. To cancel manual shift mode, return shift selector to the D
(Drive) position. The transmission returns to au-
tomatic driving mode.
When the shift selector is shifted from D (Drive)
to the manual shift gate with the vehicle stopped
or while driving, the transmission enters the
manual shift mode. Shift ranges can be selected
manually. In the manual shift mode, the shift range
is displayed on the position indicator in the meter.
When shifting the shift selector to the manual
shift gate, the position indicator displays 1 (first)
up to 6 (sixth) depending on vehicle speed.
Shift ranges up or down one by one as follows:
1⇔
2⇔ 3⇔ 4⇔ 5⇔ 6
6 (6th)
Use this position for all normal forward driving at
highway speeds.
5 (5th)
Use this position when driving up long slopes, or
for engine braking when driving down long
slopes.
4 (4th) , 3 (3rd) and 2 (2nd)
Use these positions for hill climbing or engine
braking on downhill grades. 1 (1st)
Use this position when climbing steep hills slowly
or when driving slowly, or for maximum engine
braking on steep downhill grades.
● Remember not to drive at high speeds for
extended periods of time in lower than 6th
gear. This reduces fuel economy.
When shifting up:
Move the shift selector to the + (up) side. (Shifts
to higher range.)
When shifting down:
Move the shift selector to the (down) side.
(Shifts to lower range.)
● The transmission will automatically down-
shift the gears. (For example, if you select the
3rd range, the transmission will shift down
between the 3rd and 1st gears.)
● Moving the shift selector rapidly to the same
side twice will shift the ranges in succession.
When canceling the manual shift mode:
Return the shift selector to the D (Drive) position
to return the transmission to the normal driving
mode.
Starting and driving5-17

●In the manual shift mode, the transmis-
sion may not shift to the selected gear.
This helps maintain driving perfor-
mance and reduces the chance of ve-
hicle damage or loss of control.
● In the manual shift mode, the transmis-
sion may shift up automatically to a
higher range than selected if the en-
gine speed is too high. When the ve-
hicle speed decreases, the transmis-
sion automatically shifts down and
shifts to 1st gear before the vehicle
comes to a stop.
● CVT operation is limited to automatic drive
mode when CVT fluid temperature is ex-
tremely low even if manual shift mode is
selected. This is not a malfunction. When
CVT fluid warms up, manual mode can be
selected.
● When the CVT fluid temperature is high, the
shift range may upshift in lower rpm than
usual. This is not a malfunction.
Shift lock release
If the battery charge is low or discharged, the
shift selector may not be moved from the P (Park)
position even with the brake pedal depressed
and the shift selector button pushed. To move the
shift selector, perform the following procedure:
1. Push the ignition switch to the OFF or LOCK position.
2. Apply the parking brake.
3. Remove the shift lock release cover
Aus-
ing a suitable tool.
4. Push down the shift lock release
Busing a
suitable tool. 5. Press the shift selector button
Cand move
the shift selector to the N (Neutral) position
Dwhile holding down the shift lock release.
The vehicle may be moved to the desired
location. Replace the removed shift lock re-
lease cover after the operation. If the shift
selector cannot be moved out of the P (Park)
position, have an INFINITI retailer check the
CVT system as soon as possible.
WARNING
If the shift selector cannot be moved from
the P (Park) position while the engine is
running and the brake pedal is depressed,
the stop lights may not work. Malfunction-
ing stop lights could cause an accident
injuring yourself and others.
Accelerator downshift
— in D position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
