∙Objects in the RearView Monitor will ap-
pear visually opposite compared to when
viewed in the rearview and outside mirrors.
∙ Use the displayed lines as a reference.The lines are highly affected by the num-
ber of occupants, fuel level, vehicle posi-
tion, road conditions and road grade.
∙ Make sure that the liftgate is securely closed when backing up.
∙ Do not put anything on the rearview camera. The rearview camera is installed
above the license plate.
∙ When washing the vehicle with high pressure water, be sure not to spray it
around the camera. Otherwise, water
may enter the camera unit causing water
condensation on the lens, a malfunction,
fire or an electric shock.
∙ Do not strike the camera. It is a precision instrument. Otherwise, it may malfunc-
tion or cause damage resulting in a fire or
an electric shock.
The following are operating limitations and
do not represent a system malfunction: ∙ When the temperature is extremely high or low, the screen may not clearly display
objects. ∙ When strong light directly shines on the
camera, objects may not be displayed
clearly.
∙ Vertical lines may be seen in objects on the screen. This is due to strong reflected
light from the bumper.
∙ The screen may flicker under fluorescent light.
∙ The colors of objects on the RearView Monitor may differ somewhat from the
actual color of objects.
∙ Objects on the monitor may not be clear in a dark environment.
∙ There may be a delay when switching between views.
∙ If dirt, rain or snow accumulate on the camera, the RearView Monitor may not
display objects clearly. Clean the camera.
∙ Do not use wax on the camera lens. Wipe off any wax with a clean cloth dampened
with a diluted mild cleaning agent, then
wipe with a dry cloth.

WARNING
∙ The distance guide lines and the vehiclewidth lines should be used as a reference
only when the vehicle is on a paved, level
surface. The apparent distance viewed
on the monitor may be different than the
actual distance between the vehicle and
displayed objects.
∙ Use the displayed lines and the bird’s-eye view as a reference. The lines and the
bird’s-eye view are greatly affected by
the number of occupants, cargo, fuel
level, vehicle position, road condition and
road grade.
∙ If the tires are replaced with different sized tires, the predicted course lines and
the bird’s-eye view may be displayed
incorrectly. ∙ When driving the vehicle up a hill, objects
viewed in the monitor are further than
they appear. When driving the vehicle
down a hill, objects viewed in the monitor
are closer than they appear.
∙ Objects in the rear view will appear visu- ally opposite compared to when viewed
in the monitor and outside mirrors.
∙ Use the mirrors or actually look to prop- erly judge distances to other objects.
∙ On a snow-covered or slippery road, there may be a difference between the
predicted course lines and the actual
course line.
∙ The vehicle width and predicted course lines are wider than the actual width and
course.
∙ The displayed lines will appear slightly off to the right, because the rearview
camera is not installed in the rear center
of the vehicle. Front and rear view

CAUTION
∙ Do not use leaded gasoline. Depositsfrom leaded gasoline will seriously reduce
the three-way catalyst’s ability to help
reduce exhaust pollutants.
∙ Keep your engine tuned up. Malfunctions in the ignition, fuel injection, or electrical
systems can cause over rich fuel flow into
the three-way catalyst, causing it to
overheat. Do not keep driving if the en-
gine misfires, or if noticeable loss of per-
formance or other unusual operating
conditions are detected. Have the vehicle
inspected promptly. It is recommended
that you visit an INFINITI retailer for this
service.
∙ 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 recom-
mended 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 Monitor-
ing System (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check all your
tires as soon as possible, and inflate them to
the proper pressure. 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 driv-
er’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 approximately one minute and then
remain continuously illuminated. This se-
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illumi-
nated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea-
sons, including the installation of replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunc-
tion telltale after replacing one or more tires
or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels al-
low the TPMS to continue to function prop-
erly.

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. Restart the engine using the
following procedures:1. Leave the ignition switch in the ON po- sition for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position and wait approximately
5 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the de- vice (which may have caused the inter-
ference) separate from the registered
key.
If the no start condition re-occurs, INFINITI
recommends placing the registered key on a
separate 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
whenever you refuel.
∙ Check that all windows and lights are clean.
∙ Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
∙ Check that all doors are closed.
∙ Position seat and adjust head restraints/headrests.
∙ 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 placed in the
ON position. For additional information,
refer to “Warning lights, indicator lights
and audible reminders” in the “Instru-
ments and controls” section of this
manual. 1. Apply the parking brake.
2. Press the Park button to place the ve-
hicle in P (Park) or move the shift lever to
N (Neutral). P (Park) is recommended.
The starter is designed not to operate if
the shift lever is in any of the driving
positions.
3. Push the ignition switch to the ON posi- tion. Depress the brake pedal and push
the ignition switch to start the engine.
To start the engine immediately, push
and release the ignition switch while de-
pressing the brake pedal with the ignition
switch in any position.
∙ If the engine is very hard to start in extremely cold weather or when re-
starting, depress the accelerator pedal
a little (approximately 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 be- cause it is flooded, depress the accel-
erator pedal all the way to the floor
and hold it. Push the ignition switch to
the ON position to start cranking the
engine. After 5 or 6 seconds, stop
cranking by pushing the ignition switch
BEFORE STARTING THE ENGINE STARTING THE ENGINE
Starting and driving5-17

∙ Remember not to drive at high speeds forextended periods of time in lower than
8th gear. This reduces fuel economy.
When shifting up
Use the + (up) side paddle shifter. (Shifts to
higher range.)
When shifting down
Use the (down) side paddle shifter. (Shifts
to lower range.)
∙ The transmission will automatically downshift the gears. (For example, if you
select the 3rd range, the transmission will
shift down between the 3rd and 1st
gears.)
∙ Moving the shift lever rapidly to the same side twice will shift the ranges in succes-
sion.
When canceling the manual shift mode
Move the shift lever to the D (Drive) position
to return the transmission to the normal driv-
ing mode. ∙ In the manual shift mode, the transmis-
sion may not shift to the selected gear.
This helps maintain driving performance
and reduces the chance of vehicle dam-
age or loss of control. ∙
When this situation occurs, the Continu-
ously Variable Transmission (CVT) posi-
tion indicator will blink and the chime
will sound.
∙ In the manual shift mode, the transmis-
sion may shift up automatically to a
higher range than selected if the engine
speed is too high. When the vehicle
speed decreases, the transmission auto-
matically 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 extremely low even if manual shift
mode is selected. This is not a malfunc-
tion. 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.
Accelerator downshift
— in D (Drive) position —
For passing or hill climbing, depress the ac-
celerator pedal to the floor. This shifts the
transmission down into a lower gear, de-
pending on the vehicle speed.
High fluid temperature protection
mode
This transmission has a high fluid tempera-
ture protection mode. If the fluid temperature
becomes too high (for example, when climb-
ing steep grades in high temperatures with
heavy loads, such as when towing a trailer),
engine power and, under some conditions,
vehicle speed will be decreased automatically
to reduce the chance of transmission dam-
age. Vehicle speed can be controlled with the
accelerator pedal, but the engine and vehicle
speed may be limited.
Fail-safe
When the fail-safe operation occurs, the
Continuously Variable Transmission will not
be shifted into the selected driving position.
If the vehicle is driven under extreme condi-
tions, such as excessive wheel spinning and
subsequent hard braking, the fail-safe sys-
tem may be activated. The Malfunction Indi-
cator Light (MIL) may come on to indicate
the fail-safe mode is activated. For addi-
tional information, refer to “Malfunction In-
dicator Light (MIL)” in the “Instruments and
controls” section of this manual. This will oc-
cur even if all electrical circuits are function-
ing properly. In this case, place the ignition
