AVH is short for Auto Vehicle Hold, a brake-hold system that keeps the car stopped after you lift off the brake pedal.
You’re stopped at a red light, your right foot is tired, and the car in front of you is creeping in inches at a time. That’s the moment many drivers notice an “AVH” icon or a button and wonder what it does.
In plain terms, AVH is a stop-and-go helper. Once it’s switched on, it can hold brake pressure for you when you come to a full stop. You can take your foot off the brake, rest for a bit, then move again by pressing the accelerator.
What AVH Does When You Stop
AVH is not the parking brake and it’s not cruise control. It sits in the middle. You drive normally, then when you stop and keep the brake pressed, the system can “take over” holding the car still.
Once AVH is holding the vehicle, you can lift your foot off the brake pedal. The car stays planted. When it’s time to go, you press the accelerator and the hold releases.
Most cars also show a visual cue on the dash when AVH is ready and when it’s actively holding. On many models, the indicator changes state when the system is actually holding the car still.
Where You’ll Feel It Most
- Stop-and-go traffic: fewer minutes spent pressing a pedal.
- Long red lights: you can relax your ankle and calf.
- Hills: it helps prevent roll-back while you shift your foot from brake to gas.
AVH In Cars With Electronic Parking Brakes
AVH is most common on vehicles with an electronic parking brake. That hardware makes it easier for the car to manage brake pressure and apply or release holding force with consistency.
On many models, AVH also has guardrails. It may require the driver’s seat belt to be latched and the doors to be shut. Those conditions reduce the chance of the car being held while the driver is stepping out.
Subaru’s manual supplement lays out these conditions and the basic on/off steps for Auto Vehicle Hold. You can read the exact wording in the Subaru owner’s manual supplement on Auto Vehicle Hold (AVH).
How AVH Works Step By Step
Even if your car hides the details, the flow is easy to grasp. AVH uses sensors and the brake control system to decide when it can hold the car. Then it holds brake pressure until you ask to move again.
Typical operation cycle
- You turn AVH on (button, touchscreen setting, or both).
- You drive as normal.
- You come to a full stop and keep the brake pedal pressed for a moment.
- The dash shows that AVH is actively holding.
- You release the brake pedal and the car stays stopped.
- You press the accelerator and the system releases the hold.
Common auto-release triggers
Cars treat AVH as a temporary hold, not a “park it and walk away” mode. Many systems will drop out and switch to the parking brake under certain conditions, such as a door opening, the seat belt being unlatched, or the hold running for a set time.
A U.S. safety bulletin describes one such behavior: after holding the vehicle for a defined period, the system can engage the parking brake, and it can also apply the parking brake if the driver door opens or the seat belt is unfastened. See the NHTSA service bulletin text describing AVH indicator behavior.
When To Use AVH And When To Skip It
AVH shines in routine, low-speed stops. It’s a comfort tool, not a performance tool. Treat it that way and it stays predictable.
Good moments to switch it on
- Stoplight corridors where you’ll hit three or four reds in a row
- Traffic jams that move in short bursts
- Hilly intersections where roll-back feels stressful
- School pick-up lines and drive-thru lanes
Moments to leave it off
- Parking maneuvers where you want tight, continuous pedal control
- Slick surfaces where you prefer your own brake modulation
- Car washes with conveyor belts (follow the wash’s directions)
- Towing situations where your manual calls for different stopping practice
What Is AVH in a Car? On The Dash
Drivers get tripped up because AVH often has two states: on/ready and actively holding. The dash can show one icon for the system being enabled and another cue for the hold being applied.
If you see the icon but the car still creeps when you release the brake, you may not have met the activation conditions. Come to a full stop, press the brake firmly, and check for the active-hold indicator.
AVH Behavior Cheat Sheet
This table compresses the most common AVH moments into quick checks. The wording is brand-neutral, since labels differ across dashboards.
| Situation | What You’ll Notice | What To Do |
|---|---|---|
| Stopped at a light, AVH enabled | AVH icon shows “on,” but not holding yet | Keep brake pressed until active-hold cue appears |
| Active hold engaged | Car stays still after you lift your foot | Rest your foot, stay alert, keep eyes up |
| Traffic creeps forward | Gap opens, you want to move a few feet | Tap accelerator gently, then brake again to re-hold |
| Stop on a hill | Less roll-back when moving off | Press accelerator smoothly; avoid sudden throttle |
| Seat belt unlatched while stopped | Hold may cancel or switch to parking brake | Stay on brake, relatch belt, then re-enable if needed |
| Driver door opens while stopped | System may apply parking brake | Use Park and parking brake before exiting |
| Hold runs for a set time | Some cars shift from hold to parking brake | If you’ll wait longer, shift to Park |
| Battery weak or brake system warning | AVH may refuse to engage | Follow dash warnings and get the car checked |
AVH Vs. Hill Start Assist Vs. Parking Brake
These three get mixed up because they all relate to stopping. They act at different times and for different reasons.
Auto Vehicle Hold (AVH)
Works at a complete stop. It can keep holding the car after you take your foot off the brake. You still decide when to move by pressing the accelerator.
Hill start assist
Usually works only on an incline and only for a brief moment while you switch from brake to gas. It’s meant to prevent roll-back right as you start moving. It does not usually keep the car held for long red lights.
Parking brake
Designed for parking. It’s what you use when you leave the car or when you want the car secured in Park. If your system auto-applies the parking brake after a timed hold, treat that as a cue to shift to Park and settle in.
How To Turn AVH On And Off
The control varies by vehicle. Some cars use a physical button near the shifter. Others tuck it into a driving settings menu. A few do both: a button for quick use, and a menu for deeper behavior choices.
Turn it on before you hit heavy traffic. That way you’re not hunting for a button at a light. Then, learn your car’s “ready vs holding” indicator. That one detail prevents most confusion.
Why AVH might turn itself off
Many cars default to “off” after you restart the engine. That’s not a fault; it’s a design choice. Some makers treat it as a driver-selected assist, not a permanent setting. If you want it each drive, you may need to tap the control each time.
Driving Feel And Wear
AVH should feel calm and consistent. If the release feels abrupt, ease into the accelerator. If warning lights appear or the brake feel changes and stays that way, get it checked.
Safety Habits That Keep AVH Predictable
AVH can make stops more relaxed, but it does not replace paying attention. Treat it like a helper that holds the brakes, nothing more.
- Keep your eyes up in traffic. A stopped car can still be hit from behind.
- Use Park when you expect a long wait.
- If you’re unsure whether it’s holding, keep your foot on the brake until you confirm the indicator.
Quick Troubleshooting For AVH That Won’t Engage
If the dash shows AVH is enabled but it never starts holding, run through this short list. It solves most “it doesn’t work” moments in real driving.
- Confirm you came to a full stop. Rolling stops often won’t trigger hold.
- Press the brake pedal firmly for a beat, then watch for the active-hold cue.
- Check seat belt and doors. Many systems require both.
- Make sure you’re not in Park. AVH is meant for drive or neutral states, depending on the car.
- Watch for brake, ABS, or parking brake warnings. Those can block AVH.
If warnings stay on, follow your manual and get the car inspected. AVH is tied into braking, so it’s not a place to guess.
AVH Indicators And Common Messages
This second table maps common icon states to what you should do next. Your cluster may use different colors or letters, so treat this as a pattern guide, then match it to your manual’s terms.
| Light Or Message | Meaning | Next Step |
|---|---|---|
| AVH on indicator | The system is enabled and waiting for a full stop | Stop fully, keep brake pressed until hold activates |
| AVH holding indicator | Brake pressure is being held for you | Release brake pedal, then press accelerator to move |
| AVH flashing | Conditions not met or system is transitioning | Recheck doors, belt, pedal pressure, and gear position |
| Parking brake indicator turns on during a long stop | Car switched from hold to parking brake after time or trigger | Shift to Park if you’ll remain stopped |
| Brake or ABS warning appears | Brake system issue can disable AVH | Drive cautiously and follow the warning guidance |
| “AVH unavailable” or similar text | System can’t operate right now | Restart, then check battery health and warning lights |
Picking The Right Habit For Your Daily Driving
The sweet spot is simple: turn it on when you expect repeated full stops, then turn it off when you’re doing tight parking work or any situation where you want full manual control.
Once you learn your car’s dash cues, AVH stops feeling like a mystery button and starts feeling like a normal part of driving.
