At times you may notice a decrease in operating range. This is normal for any RKE system. If the transmitter does not work or if you have to stand closer to your vehicle for the transmitter to work, try this: • Check the distance. You may be too far from your vehicle. You may need to 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 to determine if battery replacement is necessary. See "Battery Replacement" under Remote Keyless Entry (RKE) System Operation on page 115. • If you are still having trouble, see your dealer/retailer or a qualified technician for service.

If your vehicle has the remote start feature you can also start your vehicle with the RKE transmitter. The RKE transmitter, with the remote start button, provides an increased operating range of 195 feet (60 m) away. However, the operating 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 start it. There are other conditions which can affect the performance of the transmitter.
