To replace the battery:
1. Separate the transmitter with aflat, thin object, such as a flat
head screwdriver.
.Carefully insert the tool into
the notch located along the
parting line of the
transmitter. Do not insert
the tool too far. Stop as
soon as resistance is felt.
.Twist the tool until the
transmitter is separated.
2. Remove the old battery. Do not use a metal object. 3. Insert the new battery, positive
side facing down. Replace with a
CR2032 or equivalent battery.
4. Snap the transmitter back together.
Remote Vehicle Start
If available, this feature allows you
to start the engine from outside of
the vehicle. It may also start up the
vehicle's heating or air conditioning
systems and rear window defogger.
Normal operation of the system will
return after the key is turned to the
ON/RUN position.
If the vehicle has an automatic
climate control system, the climate
control system will default to a
heating or cooling mode depending
on the outside temperatures. If the
vehicle does not have an automatic
climate control system, the system
will turn on at the setting the vehicle
was set to when the vehicle was
last turned off. During a remote start, if the vehicle
has an automatic climate control
system and heated seats, the
heated seats will turn on during
colder outside temperatures and will
shut off when the key is turned to
ON/RUN. If the vehicle does not
have an automatic climate control
system, during remote start,
manually turn the heated seats on
and off. See
Heated and Ventilated
Front Seats on page 3‑10 for
additional information.
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 may run out of fuel.
