With valet parking, an attendant takes the vehicle, moves it to the parking area, and brings it back when you leave. But with a vehicle that has an interlock installed, it is hard to assume it can be moved right away just by handing over the key, as with an ordinary vehicle. An interlock is an alcohol interlock that controls vehicle starting based on the driver's breath test result; testing is done with the handset, and the control box connects to the vehicle to operate it.
In particular, the official AF-i1 information describes features that detect when the vehicle is driven without an approved test and when the device is removed from the vehicle. So whether valet parking is possible is not something to decide from the mere presence of the device; it is a matter of matching the vehicle's conditions of use with how the parking facility actually operates, before you visit. If those checks are not finished, it is better to prepare both parking without a valet and other ways of getting there, rather than setting off on the assumption of valet service.
First distinguish device features from the vehicle's conditions of use
The AF-i1 is described as detecting the temperature, humidity, speed, and strength of breath to judge whether the person being tested is blowing directly into it. It can also store vehicle ACC status, engine start, test results, and tampering-related events with date and time information. In other words, a parking attendant moving the vehicle is not simply a matter of a short-distance move; it can be linked to the device's test and driving records.
That said, this description of features alone does not let you conclude that all valet parking is possible or impossible. You need to check three things separately: the actual usage guidance for the installed device, the range of drivers set by the vehicle owner or manager, and whether the location allows parking without a valet. Programs that apply to a specific individual, and permissions to use the vehicle, may also be separate from the product's features.
Split what to check before your visit
Rather than vaguely asking one person "is valet OK?", splitting whom to ask about what makes the scope of the answers clear. The approach is to ask the device support channel about the conditions of device use, the vehicle manager about the range of people who may drive the vehicle, and the parking facility about how to park without a valet.
| Where to check | Facts to pass on | Answer you need |
|---|---|---|
| Device installation and support channel | The device model installed in the vehicle and the planned valet situation | Whether there is official usage guidance to follow in this situation |
| Vehicle owner or manager | Where the vehicle will be left and how it is expected to be used | Whether there are conditions allowing a parking attendant to move the vehicle |
| Parking facility operator | That it is an interlock-equipped vehicle and the valet arrangement is not settled | Whether there are alternatives such as self-parking, accompanied entry, or another parking area |
| Person handling the visit schedule | The travel plan if valet is not possible | Whether a schedule change or other transport is possible |
For example, this is a hypothetical situation. If a driver about to visit a hotel plans to take the vehicle with only on-site valet parking in mind, they first check the device support channel's guidance and the vehicle manager's permitted scope. Then they ask the hotel whether there is a self-parking area or a way to enter without valet service. If the answer from any one of the three is unclear, the observation is "valet conditions not confirmed." A possible action here is not to take the vehicle or to settle on another parking method, and the completion criterion is a state where both how the vehicle will be moved and the conditions of use that apply to that method are clear.
Actions not to ask of the parking attendant
You can tell the parking attendant that an interlock is installed and that you are checking the conditions for moving the vehicle. But you must not ask for improvised workarounds, such as having someone else blow into the device in your place or handing over the vehicle with the engine kept running. Changing or removing the device's connections is not an option for parking convenience either.
This distinction also relates to what the records mean. The AF-i1 stores vehicle operation and interlock usage events, and is described as allowing log events to be managed and downloaded with dedicated software. If the vehicle is moved in a way that differs from reality for the sake of convenience, it may later be hard to explain the remaining test, engine start, and driving records.
A standard for when plans change on site
You may be told at booking that self-parking is available, only to be told on arrival that only valet is available. In that case, rather than deciding how to use the device based on site staff's guesses, it is safer to relay the situation again to the device support channel or the vehicle manager you checked with before the visit. If you cannot get an answer right away, you can change your plan by finding another parking location without valet service or by getting around without the vehicle.
If a message appeared on the device screen or it behaved unexpectedly, record the message and when it occurred exactly as they were and pass them to the support channel. Deleting records or attributing them to someone else's actions to make it look as if "there was no problem" is not a solution. The completion criterion here is not hurriedly handing over the vehicle, but a state where what vehicle movement actually took place and what guidance to follow next are both clear.
When valet service is uncertain, change your travel plan
If whether valet parking is possible has not been confirmed, first look for self-parking near your destination, and if that is also difficult, consider ways that do not involve handing over the vehicle, such as riding in a companion's car, public transportation, a taxi, or adjusting your schedule. This is not a way of awkwardly avoiding the interlock, but a visit plan that keeps the device's proper use and the vehicle's management conditions intact.
If there is any doubt about drinking, the premise is not to plan on driving, regardless of whether an interlock is installed. An interlock is a device designed to carry out defined testing and start control, but it does not eliminate the risks of every driving situation or judge the conditions of valet parking for you. Before handing a vehicle to valet parking, it is realistic to confirm that the device guidance, the vehicle use permissions, and the parking facility's alternative arrangements all line up, and if even one is unsettled, to keep open the option of visiting without the vehicle.
