Remote Vehicle Start
This vehicle may have a remote
starting feature that starts the
engine from outside of the vehicle.
/(Remote Start): This button is
located on the RKE transmitter if the
vehicle has remote start.
Laws in some communities may
restrict the use of remote starters.
For example, some laws may
require a person using the remote
start to have the vehicle in view
when doing so. Check local
regulations for any requirements on
remote starting of vehicles.
Do not use the remote start feature
if the vehicle is low on fuel. The
vehicle could run out of fuel.
If the vehicle has the remote start
feature, the RKE transmitter
functions have an increased range
of operation. However, the range
may be less while the vehicle is
running. There are other conditions which
can affect the performance of the
transmitter, see

Extending Engine Run Time
To extend the engine run time by
10 minutes, repeat Steps 1 though 3
while the engine is still running. The
engine run time can only be
extended if it is the first remote start
since the vehicle has been driven.
Remote start can be extended
one time.
If the remote start procedure is
used again before the first
10 minute time frame has ended,
the first 10 minutes will immediately
expire and the second 10 minute
time frame will start.
For example, if the lock button and
then the remote start buttons are
pressed again after the vehicle has
been running for five minutes,
10 minutes are added, allowing the
engine to run for a total of
15 minutes.A maximum of two remote starts or
remote start attempts are allowed
between ignition cycles.
After the vehicle's engine has been
started two times using the remote
start button, the ignition must be
turned on and then back off before
the remote start procedure can be
used again.

the remote start feature if the key is
in the ignition, the hood is open, or if
there is an emission control system
malfunction.
The engine turns off during a remote
start if the coolant temperature gets
too high or if the oil pressure
gets low.
Vehicles that have the remote
vehicle start feature are shipped
from the factory with the remote
vehicle start system enabled. The
system may be enabled or disabled
through the DIC if the vehicle has
DIC buttons. See “REMOTE
START” underVehicle
Personalization (With DIC Buttons)
on page 5‑44for additional
information. If the vehicle does not
have DIC buttons, see your dealer/
retailer to enable or disable the
remote start system.
