Principle of Operation
The system allows you to lock and unlock your vehicle without taking the passive key out of your pocket or purse.

A valid passive key must be within one of the three external detection ranges. These are approximately
1 m (3 ft) from the front door handles and the liftgate.
The system does not function if:
- The vehicle battery has no charge.
- The passive key battery has no charge.
- The passive key frequencies are jammed.
- The passive key is too close to metal objects or electronic devices, for example keys or a cell phone.
If the system does not function, use the remote control or the key blade to lock and unlock your vehicle.
Locking the Doors
Lock sensors are on the top of all exterior door handles.

Touch a lock sensor once to lock your vehicle and arm the alarm. The direction indicators flash.
Touch a lock sensor twice within three seconds to double lock your vehicle and arm the alarm.The direction indicators flash.Do not touch the unlock sensor on the back of the door handle.
Keep the door handle clean to make sure the system correctly operates.
Note:
Your vehicle does not automatically lock. If you do not touch a lock sensor your vehicle remains unlocked.
After locking the doors with the lock sensor, there is a brief delay before you can unlock your vehicle. This delay lets you pull the handle to make sure your vehicle is locked. When the delay period is over, you can unlock the doors again, provided the passive key is within the respective detection range.
Unlocking the Doors
Unlock sensors are on the back of all exterior door handles.

Touch the unlock sensor to unlock your vehicle and disarm the alarm.The direction indicators flash.Do not touch the lock sensor on the top of the door handle.

Note:
When your vehicle remains locked for longer than three days, the system enters an energy-saving mode. This is to prevent your vehicle battery running out of charge. When your vehicle is unlocked while in this mode, the reaction time of the system may be a little longer than normal. To exit the energy-saving mode, unlock your vehicle.
Unlocking the Driver Door
You can program the unlocking function so that only the driver door unlocks when you touch the unlock sensor. See

Smart Unlocks for Passive Keys

Your vehicle locks if another passive key is within the detection range after you close the last door.
