ACC
Engine is not started.
Some electrical devices are available
(e.g. power windows etc.).
RUN
Driving position.
All the electrical devices are available
(e.g. climate controls, heated seats, etc.).
START
The engine will start.
In case the ignition switch does not change with
the push of a button, the key fob may have a low
or depleted battery. In this situation, a back up
method can be used to operate the ignition
switch. Put the nose side (side opposite of the
emergency key) of the key fob against the
START/STOP ignition button and push to
operate the ignition switch.
Back Up Starting Method

NOTE:The key fob may not be detected by the
vehicle Keyless Enter-N-Go system if it is
located next to a mobile phone, laptop or
other electronic device; these devices may
block the key fob’s wireless signal and
prevent the Keyless Enter-N-Go system from
starting the vehicle.
For more information on the engine starting
procedure, see Ú page 118.
WARNING!
When exiting the vehicle, always remove
the key fob from the vehicle and lock your
vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended is dangerous for a number of
reasons. A child or others could be seriously
or fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the gear selector.

Do not leave the key fob in or near the vehicle,
or in a location accessible to children, and do
not leave the ignition of a vehicle equipped with
Keyless Enter-N-Go in the ON/RUN mode.
A child could operate power windows, other
controls, or move the vehicle.

Do not leave children or animals inside
parked vehicles in hot weather. Interior heat
build-up may cause serious injury or death.

CAUTION!
An unlocked vehicle is an invitation for
thieves. Always remove key fob from the
vehicle and lock all doors when leaving the
vehicle unattended.

REMOTE START — IF EQUIPPED
(GASOLINE)
This system uses the key fob to start
the engine conveniently from outside
the vehicle while still maintaining
security. The system has a range of
approximately 300 ft (91 m).
Remote start is used to defrost windows in cold
weather, and to reach a comfortable climate in
all ambient conditions before the driver enters
the vehicle.
NOTE:
Obstructions between the vehicle and the key
fob may reduce this range Ú page 449.
HOW TO USE REMOTE START

Push and release the Remote Start button on the
key fob twice within five seconds. The parking
lights will flash, vehicle doors will lock, and the
horn will chirp twice (if programmed). Once the
vehicle has started, the engine will run for
15 minutes.

Pushing the remote start button a third time
shuts the engine off.
To drive the vehicle, push the unlock button,
insert the key into the ignition, and turn to the
ON/RUN position. NOTE:
With Remote Start, the engine will only run
for 15 minutes.
Remote Start can only be used twice.
If an engine fault is present or fuel level is
low, the vehicle will start and then shut down
in 10 seconds.
The parking lights will turn on and remain on
during Remote Start mode.
For security, power window operation is
disabled when the vehicle is in the Remote
Start mode.
The ignition must be placed in the ON/RUN
position before the Remote Start sequence
can be repeated for a third cycle.
If your power door locks were unlocked,
Remote Start will automatically lock the
doors.
WARNING!
Do not start or run an engine in a closed
garage or confined area. Exhaust gas
contains Carbon Monoxide (CO) which is
odorless and colorless. Carbon Monoxide is
poisonous and can cause serious injury or
death when inhaled.
Keep key fobs away from children. Opera
-
tion of the Remote Start System, windows,
door locks or other controls could cause
serious injury or death.

Automatic Temperature Control (ATC) — If
Equipped
The climate controls automatically adjust to an
optimal temperature and mode, dependent on
the outside ambient temperature. When the
ignition is placed in the ON/RUN position, the
climate controls will resume their previous
settings.
Manual Temperature Control (MTC) — If
Equipped
In ambient temperatures of 40°F (4.5°C) or
below, the climate settings will default to
maximum heat, with fresh air entering the
cabin. If the front defrost timer expires, the
vehicle will enter Mix Mode.
In ambient temperatures from 40°F (4.5°C)
to 78°F (26°C), the climate settings will be
based on the last settings selected by the
driver.

In ambient temperatures of 78°F (26°C) or
above, the climate settings will default to MAX
A/C, Bi-Level mode, with Recirculation on.

For more information on ATC, MTC, and climate
control settings, see Ú page 58. NOTE:
These features will stay on through the duration
of remote start, or until the ignition is placed in
the ON/RUN position. The climate control
settings will change, and exit the automatic
defaults, if manually adjusted by the driver
while the vehicle is in remote start mode.
This includes turning the climate controls off
using the OFF button.

REMOTE START — IF EQUIPPED (DIESEL)
This system uses the key fob to start
the engine conveniently from outside
the vehicle while still maintaining

approximately 300 ft (91 m).
Remote start is used to defrost windows in cold
weather, and to reach a comfortable climate in
all ambient conditions before the driver enters
the vehicle.
NOTE:
Obstructions between the vehicle and the
key fob may reduce this range.
