REARVIEW MONITOR SYSTEM
LIMITATIONS
WARNING
Listed below are the system limitations
for RearView Monitor. Failure to oper-
ate the vehicle in accordance with these
system limitations could result in serious
injury or death.
.The system cannot completely elim-
inate blind spots and may not show
every object.
. Underneath the bumper and the
corner areas of the bumper cannot
be viewed on the RearView Monitor
because of its monitoring range lim-
itation. The system will not show
small objects below the bumper, and
may not show objects close to the
bumper or on the ground.
. Objects viewed in the RearView
Monitor differ from actual distance
because a wide-angle lens is used.
. Objects in the RearView Monitor will
appear 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
number of occupants, fuel level, ve-
hicle position, road conditions and
road grade.
. Make sure that the trunk lid is
securely closed when backing up.
. Do not put anything on the rearview
camera. The rearview camera is in-
stalled 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 malfunction 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 is directly coming 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 to
the RearView Monitor.
. If dirt, rain or snow accumulates on the
camera, the RearView Monitor may not
display object 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.

position or push the CAMERA button to
display the Around View
®Monitor on the
upper display.
Available views
WARNING
. The distance guide line and the
vehicle width line should be used as
a reference only when the vehicle is
on a paved, level surface. The dis-
tance viewed on the monitor is for
reference only and 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 af-
fected by the number of occupants,
fuel level, vehicle position, road con-
dition and road grade.
. If the tires are replaced with different
sized tires, the predictive course lines
and the bird’s-eye view may be dis-
played incorrectly. .
When driving the vehicle up a hill,
objects viewed in the monitor are
farther than they appear. When driv-
ing the vehicle down a hill, objects
viewed in the monitor are closer than
they appear.
. Objects in the rear view will appear
visually opposite compared to when
viewed in the rear view and outside
mirrors.
. Use the mirrors or actually look to
properly judge distances to other
objects.
. The distance between objects viewed
in the rear view differs from actual
distance because a wide-angle lens is
used.
. On a snow-covered or slippery road,
there may be a difference between
the predictive course lines and the
actual course line.
. The vehicle width and predictive
course lines are wider than the actual
width and course.
. The displayed lines on the rear view
will appear slightly off to the right
because the rearview camera is not
installed in the rear center of the
vehicle.SAA1840

THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol 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 compo-
nents.
. 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.
CAUTION
.Do not use leaded gasoline. Deposits
from leaded gasoline seriously reduce
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
driving if the engine misfires, or if
noticeable loss of performance or
other unusual operating conditions
are detected. Have the vehicle in-
spected promptly. It is recommended
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 Mon-
itoring 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 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.
For models with run-flat tires, if the vehicle
is being driven with one or more flat tires,
the low tire pressure warning light will
illuminate continuously and a chime will
sound for 10 seconds. The flat tire warning
will also appear in the vehicle information
display. The chime will only sound at the first
indication of a flat tire, and the warning light
will illuminate continuously. When the flat
tire warning is activated, it is recommended
you have the system reset and the tire
checked and replaced if necessary by an
INFINITI retailer. Even if the tire is inflated
to the specified COLD tire pressure, the
warning light will continue to illuminate until
the system is reset by an INFINITI retailer.
Your vehicle can be driven for a limited time
on a flat tire. See “Run-flat tires” (P.8-32).

4. Push the ignition switch while depressing the brake pedal within 10 seconds after
the chime sounds. The engine will start.
After step 3 is performed, when the ignition
switch is pushed without depressing the
brake pedal, the ignition switch position will
change to ACC.
NOTE:
. When the ignition switch is pushed to
the ACC or ON position or the engine is
started by the above procedures, the
Intelligent Key battery discharge indi-
cator appears in the vehicle information
display even if the Intelligent Key is
inside the vehicle. This is not a malfunc-
tion. To turn off the Intelligent Key
battery discharge indicator, touch the
ignition switch with the Intelligent Key
again.
. If the Intelligent Key battery discharge
indicator appears, replace the battery as
soon as possible. (See “Intelligent Key
battery replacement” (P.8-19).)
. Make sure the area around the vehicle is
clear.
. Check fluid levels such as engine oil,
coolant, brake fluid and window 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.
. 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 lights, in-
dicator lights and audible reminders”
(P.2-10).)
BEFORE STARTING THE ENGINE

1. Apply the parking brake.
2. Move the shift lever to the P (Park) or N(Neutral) position. (P is recommended.)
The starter is designed not to operate
unless the shift lever is in either of the
above positions.
3. Push the ignition switch to the ON position. Firmly 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
depressing the brake pedal with the
ignition switch in any position.
.If the engine is very hard to start inextremely cold weather or when re-
starting, depress the accelerator ped-
al 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
because it is flooded, depress the
accelerator 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 to OFF. After
cranking the engine, release the accel-
erator pedal. Crank the engine withyour foot off the accelerator pedal
by
depressing the brake pedal and push-
ing 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
OFF and wait 10 seconds before crank-
ing again, otherwise the starter could be
damaged.
4. Warm-up
Allow the engine to idle for at least 30
seconds 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 engine running for a
minimum of 2 - 3 minutes before shut-
ting it off. Starting and stopping the
engine over a short period of time may
make the vehicle more difficult to start.
When racing the engine up to 4,500 rpm
or more under no load condition, the
engine will enter the fuel cut mode. 5. To stop the engine, shift the shift lever to
the P (Park) position and push the
ignition switch to the OFF position.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
REMOTE ENGINE START (if so
equipped)
Vehicles started with the remote engine
start function require the ignition switch to
be placed in the ON position before the shift
lever can be moved from the P (Park)
position. To place the ignition switch in the
ON position, perform the following steps:
1. Make sure that the Intelligent Key is on you.
2. Depress the brake pedal.
3. Push the ignition switch once to the ON position.
Starting and driving5-15
STARTING THE ENGINE

4M(4th), 3M(3rd) and 2M(2nd):
Use these positions for hill climbing or engine
braking on downhill grades.
1
M(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.
. Moving the shift lever rapidly to the same
side twice will shift the ranges in succes-
sion.
. In the manual shift mode, the transmis-
sion may not shift to the selected gear
or may automatically shift to the other
gear. This helps maintain driving per-
formance and reduces the chance of
vehicle damage or loss of control.
. When the transmission does not shift to
the selected gear, the Automatic Trans-
mission (AT) position indicator (in the
vehicle information display) will blink
and the buzzer will sound.
. In the manual shift mode, the transmis-
sion automatically shifts down to 1st
gear before the vehicle comes to a stop.
When accelerating again, it is necessary
to shift up to the desired range.
Accelerator downshift — In D (Drive)
position —
For passing or hill climbing, fully depress the
accelerator pedal to the floor. This shifts the
transmission down into the lower gear,
depending on the vehicle speed.
Fail-safe
When the fail-safe operation occurs, note
that the transmission will be locked in any of
the forward gears according to the condi-
tion.
If the vehicle is driven under extreme
conditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safe
system may be activated. This will occur
even if all electrical circuits are functioning
properly. In this case, push the ignition
switch to the OFF position and wait for 3
seconds. Then push the ignition switch back
to the ON position. The vehicle should
return to its normal operating condition. If
it does not return to its normal operating
condition, have the transmission checked
and repaired, if necessary. It is recom-
mended you visit an INFINITI retailer for
this service.

STANDARD MODE
Allows for optimum driving according to the
driving conditions.
This mode will be selected first each time the
engine is started.
SPORT+ MODE (if so equipped)
In addition to the characteristics of the
SPORT mode, this mode heightens steering
response and changes the setting of VDC
(Vehicle Dynamic Control) for a more sporty
driving experience.
NOTE:
.VDC operation is reduced when the
INFINITI Drive Mode Selector is used
to select the SPORT+ mode. The VDC
system may not operate in the same
circumstances when compared to op-
eration in the standard mode. To help
prevent accidents drive carefully, avoid
careless or dangerous driving techniques
and be especially careful when driving
and cornering on slippery surfaces.
. In the SPORT+ mode, fuel economy may
be reduced.
SPORT MODE
. Adjusts the engine and transmission
points for a higher response.
. The setting of the steering system is
adjusted to provide a quick steering
response and a heavy steering effort.
. The setting of the suspension system is
adjusted to increase the damping force
(if so equipped).
NOTE:
In the SPORT mode, fuel economy may be
reduced.
SNOW MODE
Changes the engine characteristics to aid
driving on slippery roads.
ECO MODE
Assists the driver’s eco-driving. The engine
and transmission points are adjusted for
improved fuel economy, providing such a
driving features as smooth starting or con-
stant cruising.
NOTE:
Selecting the ECO mode will not necessarily
improve fuel economy as many driving
factors influence its effectiveness.
Operation
Select the ECO mode using the INFINITI
Drive Mode Selector. The ECO drive indica-
tor light on the instrument panel illuminates.
When the accelerator pedal is depressed
within the range of economy drive, the ECO
drive indicator light illuminates in green.
When the accelerator pedal is depressed
above the range of economy drive, the ECO
drive indicator light turns off. For ECO pedal
system equipped models, see “ECO pedal
system” (P.5-22).
The ECO drive indicator light will not
illuminate in the following cases:
. When the shift lever is in the R (Reverse)
position.
. When the vehicle speed is below 2 MPH
(3.2 km/h) or over 90 MPH (144 km/h).
. When the cruise control (if so equipped)
or the Intelligent Cruise Control (ICC)
system (if so equipped) is operated.
ECO pedal system (if so equipped)
The ECO pedal system helps assist the driver
to improve fuel economy by increasing the
reaction force of the accelerator pedal.
When the ECO drive indicator light is
blinking or remains off, the ECO pedal
system increases the reaction force of the
accelerator pedal.
