Other conditions can affect the performance
of the Intelligent Key transmitter. See “In-
telligent Key system” (P.3-7) 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-
21).
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-
21). 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.
CANCELING A REMOTE START
To cancel a remote start, perform one of the
following:
. Aim the Intelligent Key at the vehicle and
push and hold the remote engine start
button until the parking lights turn
off.
. Turn on the hazard warning flashers.
. Cycle the ignition switch ON and then
OFF.
. The extended engine run time has ex-
pired.
. The first 10 minute timer has expired.
. The engine hood has been opened.
. The shift lever is moved out of P (Park).
. The alarm sounds due to illegal entry into
the vehicle.

FUEL-FILLER DOOR

The automatic drive positioner system has
two features:
.Entry/exit function
. Memory storage
ENTRY/EXIT FUNCTION
This system is designed so that the driver’s
seat and steering column will automatically
move when the shift lever is in the P (Park)
position. This allows the driver to get into
and out of the driver’s seat more easily.

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 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

1M(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.
