Other conditions can affect the performance
of the Intelligent Key transmitter. See “In-
telligent Key system” (P.3-6) for additional
information.
REMOTE ENGINE START OPER-
ATING RANGE
The remote engine start function can only be
used when the Intelligent Key is within the
specified operating range from the vehicle.
When the Intelligent Key battery is dis-
charged or other strong radio wave sources
are present near the operating location, the
Intelligent Key operating range becomes
narrower, and the Intelligent Key may not
function properly.
The remote engine start operating range is
approximately 197 ft (60 m) from the
vehicle.
REMOTE STARTING THE ENGINE
To use the remote start function to start the
engine, perform the following:
1. Aim the Intelligent Key at the vehicle.
2. Push the LOCK
button to lock all
doors.
3. Within 5 seconds push and hold the remote engine start
button until
the turn signal lights flash and the tail lights illuminate. If the vehicle is not
within view, push and hold the remote
engine start
button for at least 2
seconds.
The following events will occur when the
engine starts:
. The front parking lights will turn on and
remain on as long as the engine is
running.
. The doors will be locked and the air
conditioner system may turn on.
. The engine will continue to run for about
10 minutes. Repeat the steps to extend
the time for an additional 10 minutes.
See “Extending engine run time” (P.3-
20).
. The rear window glass and outside mirror
defroster may turn on automatically
when the outside air temperature, the
interior temperature and the engine
coolant temperature are low.
Depress and hold the brake pedal, then place
the ignition switch in the ON position before
driving. For further instructions, see “Driving
the vehicle” (P.5-16).
EXTENDING ENGINE RUN TIME
The remote engine start function can be
extended one time by performing the steps
listed in “Remote starting the engine” (P.3-
20). Run time will be calculated as follows:
. The first 10 minute run time will start
when the remote engine start function is
performed.
. The second 10 minutes will start imme-
diately when the remote engine start
function is performed. For example, if
the engine has been running for 5
minutes, and 10 minutes are added, the
engine will run for a total of 15 minutes.
. Extending engine run time will count
towards the two remote engine start
limit.
A maximum of two remote engine starts, or
a single start with an extension, are allowed
between ignition cycles.
The ignition switch must be cycled to the ON
position and then back to the OFF position
before the remote engine start procedure
can be used again.

How to park with predictive course
lines
WARNING
.
If the tires are replaced with different
sized tires, the predictive course lines
may not be displayed correctly.
. On a snow-covered or slippery road,
there may be a difference between
the predictive course lines and the
actual course line.
. The displayed lines will appear
slightly off to the right because the
rearview camera is not installed in the
rear center of the vehicle.
. If the battery is disconnected or
becomes discharged, the predictive
course lines may be displayed incor-
rectly. If this occurs, please perform
the following procedures:
— Turn the steering wheel from lock to lock while the engine is running.
— Drive the vehicle on a straight road for more than 5 minutes.

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).

INTELLIGENT KEY BATTERY DIS-
CHARGE
If the battery of the Intelligent Key is
discharged, or environmental conditions in-
terfere with the Intelligent Key operation,
start the engine according to the following
procedure:
1. Move the shift lever to the P (Park)position.
2. Firmly apply the foot brake.
3. Touch the ignition switch with the Intelligent Key as illustrated. (A chime

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

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.
