3. Slide the new battery into the transmitter with
the positive side of the battery facing down.
Use a type CR2032 battery, or equivalent
type. Make sure the cover is on tightly,
so water will not get in.
4. Snap the front and the back of the
transmitter together.
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. Normal operation of the
system will return after the key is turned to the
RUN position.
If your vehicle has an automatic climate control
system, during remote start, the climate control
system will default to a heating mode during colder
outside temperatures and a cooling mode during
warmer outside temperatures. If your vehicle
does not have an automatic climate controlsystem, during remote start the climate control
system will turn on at the setting the vehicle was
set to when the vehicle was last turned off.
If your vehicle has heated seats, they will turn
on during colder outside temperatures and will shut
off when 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 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 your vehicle
is low on fuel. Your vehicle may run out of fuel.
The RKE transmitter with the remote start
button, provides an increased range of operation.
However, the range may be less while the
vehicle is running. As a result, you may need to
be closer to your vehicle to turn it off, than
you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote
Keyless Entry (RKE) System on page 94for
additional information.

efficient airow and temperature control, keep
the outlet in the fully opened position.
Operation Tips

Keep the hood and front air inlets free of ice,
snow, or any other obstruction, such as
leaves. The heater and defroster will work far
better, reducing the chance of fogging the
inside of your windows.
Keep the air path under the front seats clear
of objects. This helps air to circulate
throughout your vehicle.
Adding outside equipment to the front of your
vehicle, such as hood-air deectors, etc.,
may affect the performance of the heating
and air conditioning system. Check with
your dealer before adding equipment to the
outside of your vehicle.

Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
It also provides an indicator of how hard your
vehicle is working. During a majority of the
operation, the gage will read 210°F (100°C) or
less. If you are pulling a load or going up hills,
it is normal for the temperature to uctuate
and approach the 250°F (122°C) mark. If the
gage reaches the 260°F (125°C) mark, it indicates
that the cooling system is working beyond
its capacity.
