To replace the battery:
1. Separate the transmitter with a
flat, 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
This vehicle may have a remote
start feature. This feature allows
you to start the engine from outside
the vehicle. It may also start the
vehicle's heating or air conditioning
systems. See Climate Control
Systems on page 8 1 for additional
information.
Laws in some local communities
may restrict the use of remote
starters. For example, some laws
may require a person using remote
start to have the vehicle in view
when doing so.
Keys, Doors and Windows
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.
If the vehicle has the remote start
feature, the RKE transmitter
functions will 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 Remote Keyless
Entry (RKE) System on page 2 2 for
additional information.
