Keys
Do not leave the key in your vehicle with children and keep them in a place where your children will not find or play with them:
Leaving children in a vehicle with the key is dangerous. This could result in someone being badly injured or even killed. Children may find these keys to be an interesting toy to play with and could cause the power windows or other controls to operate, or even make the vehicle move.

Keyless Entry System
Keyless Entry System
This system uses the key buttons to remotely lock and unlock the doors, liftgate, and fuel-filler flap, and opens/closes the liftgate.

Operating the theft-deterrent system is also possible on theft-deterrent system-equipped vehicles.
System malfunctions or warnings are indicated by the following warning lights or beeps.
Check the displayed message for more information and, if necessary, have the vehicle inspected at an expert repairer (we recommend an Authorised Mazda Repairer), according to the indication.
