Notes
For safety, turn off the ignition before cleaning the

connectors, and remove the key from the ignition
switch.

Never touch the connectors directly with your fingers

or with any metal device.

Replacing the lithium battery

Under normal conditions, batteries will last
approximately 1 year. (The service life may be
shorter, depending on the conditions of use.)
When the battery becomes weak, the range of the
card remote commander becomes shorter.
Replace the battery with a new CR2025 lithium
battery.

immediately consult a doctor.
