Remote engine start system
(dealer option)
WARNING
. There are some general precau-
tions when starting the engine.
Carefully read the precautions
described in “General precau-
tions when starting engine ”F 7-
9.
. Do not remote start a vehicle in
an enclosed environment (e.g.
closed garage). Prolonged opera-
tion of a motor vehicle in an
enclosed environment can cause
a harmful build-up of Carbon
Monoxide. Carbon Monoxide is
harmful to your health. Exposure
to high levels of Carbon Monox-
ide can cause headaches, dizzi-
ness or in extreme cases uncon-
sciousness and/or death.
. Before performing any servicing
of the vehicle, temporarily place
the remote engine start system in
service mode to prevent the
system from unexpectedly start-
ing the engine.
The remote engine start system allows you to start the engine from outside the
vehicle. In addition, the remote engine
start system can activate the heater or air
conditioner, providing you with a comfor-
table cabin upon entry.NOTE
The length of time for which it is
acceptable to allow the engine to
remain idling may be bound by local
laws and regulations. Check the local
rules when using the remote engine
start system.

with push-button start system”:
In the event that the vehicle ’s battery is
replaced, discharged or disconnected,
it will be necessary to start the vehicle
a minimum of one time using the key
prior to activating the remote engine
start system. This is required to allow
the vehicle electronic systems to re-
synchronize.
! Changing the batteries
CAUTION
.Do not let dust, oil or water get on
or in the remote engine start
transmitter when replacing the
battery.
. Be careful not to damage the
printed circuit board in the re-
mote engine start transmitter
when replacing the battery.
. Be careful not to allow children to
touch the battery and any re-
moved parts; children could
swallow them. .
There is a danger of explosion if
an incorrect replacement battery
is used. Replace only with the
same or equivalent type of bat-
tery.
. Batteries should not be exposed
to excessive heat such as sun-
shine, fire or the like.
For models with “keyless access with
push-button start system ”:
Perform the procedure described in “Re-
placing battery of access key ”F 11-44.
For models without “keyless access
with push-button start system”:
The two 3-volt lithium batteries (model

start transmitter should last approximately
one year, depending on usage. When the
batteries begin to weaken, you will notice
a decrease in range (distance from the
vehicle that your remote control operates).
Follow the instructions below to change
