Starting the Engine Using Remote
Start
To start the engine using the remote
start feature:
1. Aim the Remote Keyless Entrytransmitter at the vehicle.
2. Press
Q.
3. Immediately after completing Step 2, press and hold
/until
the turn signal lamps flash, or for
about 2 seconds if the vehicle is
not in view.
Once the vehicle is started, the
parking lamps will turn on and
remain on as long as the engine
is running.
Turn the ignition to ON/RUN
(key access), or select the
ON/RUN/START ignition position
(keyless access), to drive the
vehicle. The engine will shut off after
10 minutes unless a time
extension is done or the ignition
is put in ON/RUN (key access) or
ON/RUN/START (keyless access).
Vehicles with an automatic climate
control system will default to a
heating or cooling mode depending
on the outside temperature during a
remote start. When the key is turned
to ON/RUN (key access), or the
ON/RUN/START ignition position
is selected (keyless access), the
climate control system will turn on
at the setting the vehicle was set to
when the vehicle was last turned off.
Vehicles with heated or heated and
ventilated front seats can have this
feature turn on automatically during
a remote start. See
“Remote Start
Heated Seats” and“Remote Start
Vented Seats” underVehicle
Personalization on page 5‑39
for more information. Extending Engine Run Time
For a 10-minute extension, repeat
Steps 1 and 2 while the engine is
still running. The remote start can
only be extended once.
When the remote start is extended,
the second 10 minutes will start
immediately.
For example, if the vehicle has
been running for five minutes, and
10 minutes are added, the engine
will run for a total of 15 minutes.
A maximum of two remote starts or
remote start attempts are allowed
between ignition cycles.
The vehicle's ignition must be
turned on and then back off before
the remote start procedure can be
used again.
