WARNING
To avoid risk of injury or death, do not
use the remote engine start function
when the vehicle is in an enclosed area
such as a garage.
JVP0437X
The remote engine startbutton is on the
Intelligent Key if the vehicle has remote
engine start function. This function allows
the engine to start from outside the vehicle.
Automatic climate control system will auto-
matically adjust the passenger compartment
to be the set appropriate temperature when
the remote engine start function is used.
Laws in some local communities may restrict
the use of remote starters. For example,
some laws require a person using remote
start to have the vehicle in view. Check local
regulations for any requirements.
Other conditions may affect the remote
engine start function. See “Conditions the
remote start will not work” (P.3-20). Other conditions can affect the performance
of the Intelligent Key transmitter. See “In-
telligent Key system” (P.3-6).
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 strong radio waves are present
near the operating location, the Intelligent
Key operating range becomes narrower, and
the Intelligent Key may not function prop-
erly.
The remote engine start operating range is
approximately 197 ft (60 m) from the
vehicle.
REMOTE STARTING THE ENGINE

about 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).
Depress the brake pedal and place the
ignition switch in the ON position before

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-
19). 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 start limit.
A maximum of two remote starts, or a single
start with an extension, are allowed be-
tween 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.

avoid injury do not open the hood.
Pre-driving checks and adjustments3-21
HOOD

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. 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 hybrid system.
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.
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 - Visit
dealer” 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 con-
tinuously. 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. Your vehicle can be driven for a limited
time on a flat tire. See “Run-flat tires” (P.8-
34).
Starting and driving5-5

5-14Starting and driving
the brake pedal within 10 seconds after
the chime sounds. The hybrid system 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 hybrid
system is started by the above proce-
dures, the Intelligent Key battery dis-
charge indicator appears in the vehicle
information display even if the Intelli-
gent Key is inside the vehicle. This is not
a malfunction. 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.8-21).) .
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.2-9).) 1. Apply the parking brake.
2. Move the shift lever to P (Park) position.
The INFINITI Direct Response Hybrid
®
System is designed not to operate if the
shift lever is not in the P (Park) position.
3. Depress the brake pedal and push the ignition switch to start the hybrid sys-
tem. The READY to drive indicator light
will illuminate on the meter.
When starting the hybrid system at very
low outside temperatures, the READY
to drive indicator light will flash and it
may take longer for the READY to drive
indicator light to illuminate.
. The hybrid system may not start even
with the READY to drive indicator light
illuminated. Once the READY to drive
indicator light is illuminated you may
begin driving the vehicle.
. You may hear a sound in the engine
compartment when the brake pedal is
depressed with the hybrid system off.
This does not indicate a problem.
NOTE:
Care should be taken to avoid situations
that can lead to potential 12-volt battery
discharge and potential no-start conditions
such as:
1. Installation or extended use of electro-
nic accessories that consume 12-volt
