To replace the battery in the remote keyless entry
transmitter, do the following:
1. Insert a flat object, with a thin edge, into the notch
located below the remote alarm button, and
separate the bottom half from the top half of the
transmitter.
2. Remove the old battery. Do not use a metal object
to do this.
3. Slide the new battery into the transmitter with the
positive side of the battery facing up. Use a type
CR2032 battery, or equivalent type.
4. Snap the front and the back of the transmitter
together. Make sure the cover is on tight, so
water will not get in.
5. Test the operation of the transmitter with
the vehicle.
Remote Vehicle Start
Your vehicle may have a remote starting feature. 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.
When the remote start system is active and the vehicle
has an automatic climate control system, it will
automatically regulate the inside temperature. Normal
operation of the system will return after the key is turned
to RUN.
Laws in some 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. Check local regulations for any
requirements on remote starting of vehicles.
