JVP0445X
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.
Some systems, such as the air conditioner
system, will turn on during a remote start, if
the system was on the last time the ignition
switch was turned off.
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 engine start will not work” (P.3-20).
REMOTE ENGINE START (if so equipped)

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-
19).
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.5-17).
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.

following:
. Aim the Intelligent Key at the vehicle and
push and hold the remote engine start
button until the front parking lights
turn off.

. Cycle the ignition switch ON and then
OFF.
. The extended engine run time has ex-
pired.
