Remote Keyless Entry (RKE)
System
If this vehicle has the Remote Keyless Entry (RKE)
system, it operates on a radio frequency subject
to Federal Communications Commission (FCC) Rules
and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.If there is a decrease in the RKE operating range,
try this:
•Check the distance. The transmitter may be too far
from the vehicle. Stand closer during rainy or
snowy weather.
•Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
•Check the transmitter’s battery. See “Battery
Replacement” later in this section.
•If the transmitter is still not working correctly, see
your dealer/retailer or a qualified technician for
service.

Remote Keyless Entry (RKE)
System Operation
For vehicles with the Remote Keyless Entry (RKE)
System, transmitter functions work up to 30 feet (9 m)
away from the vehicle.
LOCK:Press to lock all the doors.
UNLOCK:Press once to unlock the driver door.
Press this button again within five seconds to unlock all
the doors. The interior dome lamp comes on for about
40 seconds or until the ignition switch is activated.
Programming Transmitters to the
Vehicle
Only RKE transmitters programmed to the vehicle
will work. If a transmitter is lost or stolen, a replacement
can be purchased and programmed through your
dealer/retailer. When the replacement transmitter is
programmed to the vehicle, all remaining transmitters
must also be programmed. Any lost or stolen transmitters
no longer work once the new transmitter is programmed.
Each vehicle can have up to four transmitters
programmed to it.
Battery Replacement
Notice:When replacing the battery, do not touch
any of the circuitry on the transmitter. Static
from your body could damage the transmitter.
2-4
1. Separate the transmitter with a flat, thin object
inserted into the slot near the key ring hole.
2. Remove the battery.
3. Insert the new battery, positive (+) side down.
Replace with a CR2032 or equivalent battery.4. Align the transmitter back together.
5. Check the operation of the transmitter. If the
transmitter does not work after battery replacement,
it may need to be resynchronized to the vehicle.
SeeResynchronizationfollowing.
Resynchronization
Resynchronization may be necessary due to the
security method used by this system. The transmitter
does not send the same signal twice to the receiver. The
receiver will not respond to a signal it has been sent
previously. This prevents anyone from recording
and playing back the signal from the transmitter.
To resynchronize the transmitter, stand close to the
vehicle and simultaneously press and hold the LOCK
and UNLOCK buttons on the transmitter for at least
five seconds. The door locks should cycle to confirm
resynchronization. If the locks do not cycle, see
your dealer/retailer for service.

Battery
This vehicle has two or more maintenance free batteries.
When it is time for a new battery, see your dealer/retailer
for one that has the replacement number shown on
the original battery’s label.
Warning:Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.
Vehicle Storage
{CAUTION:
Batteries have acid that can burn you and gas that
can explode. You can be badly hurt if you are not
careful. SeeJump Starting on page 5-62for tips
on working around a battery without getting hurt.
Infrequent Usage: If the vehicleis driven infrequently,
remove the black, negative (−) cable from each battery.
This helps keep the batteries from running down.
Extended Storage: For extended storage of the vehicle,
remove the black, negative (−) cable from each battery or
use a battery trickle charger. This helps maintain the
charge of the batteries over an extended period of time.
When ready to use the vehicle again, refer to the engine
starting procedure in the Index.
