Toyota C-HR Keeps Beeping? (16 Common Causes)

The CH-R is a funky crossover that’s brimming with style.

It’s loaded with tech goodies and uses various beeps, chimes and tones to alert the driver.

If your C-HR keeps beeping and you’re unsure why, this article is here to help…

Toyota CH-R Beeping

The most common causes of beeping on a Toyota CH-R include speed camera warnings, speed limit warnings, low key fob battery, faulty sensors and dash cameras.

1. Speed Camera Warnings

A very common cause of mysterious beeps on the CH-R is due to speed camera warnings. These beeps are designed to remind you to not exceed the speed limit.

Next time you are driving, put the navigation on the screen and you will be able to see the distance to the camera also.

To disable the speed camera warnings:

  1. On the display, go to “Settings”
  2. Select “Map Settings”
  3. Scroll down and untick the option to show safety cameras

Here’s what a handful of owners had to say on

“Two beeps often means that it has detected a speed camera coming up. I find 3 beeps is the lane departure warning.”

“Different sounds for different speeds cameras. Static cameras normally double beeps, average speed cameras single boing at start and end.
LDW also alarms when moving across white lines without indicating.”

“Thanks for your helpful replies. Got to the bottom of it tonight. I switched the sat nav on and drove the same route again. Sure enough, it double-beeped at the normal place but this time it popped up telling me there is a speed camera 500 yds ahead!”

2. Low Key Fob Battery

The CH-R will beep when one or more of the key fobs are low on battery.

  • You may need to change the battery in all of your fobs.
  • Ensure the battery is inserted correctly and the inside of the key fob is free from dirt and dust.

“I had same beeping just moment after starting and other time around 30km/h. Changed today battery for key (CR 2032), thats all, beeping gone.” –

“I changed the batteries to both keys (in use and spare) and now C-HR seems to work fine. No beep-beep any more. This means I don’t have to drive 80 km to Toyota maintenance, spend there few hours and then drive back another 80 km.” –

3. Speed Limit Warnings

If you exceed the speed limit you may hear a warning beep. We advise sticking to the speed limit however you can also disble this feature in car settings.

“You’ll also get beeps if you go over the speed limit (adjustable in car settings). And the car sometimes reads the wrong speed limit (ex. from a road / lane next to the one you’re driving on).” –

“When your car is going faster than the speed limit and you are approaching a speed camera, it beeps. It gets the camera data online, so you should be connected to the internet.” –

4. Faulty Sensors

Sensors are used for various driver assistance features – many of which use beeps to alert the driver. If the sensors are damaged or dirty then you may hear some mysterious beeps.

Visually inspect the car’s sensors for any obvious signs of damage, water ingress or excessive buildup of dirt.

They might just need a clean although signs of damage may not be obvious and you will need to ask your dealer to take a closer look.

Here’s one owner’s account from

“So, the CHR is at the dealers… just had phone call… mechanic believes the front sensors have gone faulty, they are replacing the whole lot – wiring loom included (short circuit the theory)… should get the car back tomorrow, all done on warranty”

“Update for you… the Toyota technician found water ingress on the sensors and has replaced them… how the water got there, who knows, but for now, all is good!”

5. Toyota Safety Sense

The Toyota Safety Sense (TSS) is comprised of various safety features, such as:

  • Pre-Collision System with Pedestrian Detection
  • Dynamic Radar Cruise Control
  • Lane Departure Alert with Steering Assist
  • Lane Tracing Assist
  • Road Sign Assist
  • Automatic High Beams
  • Proactive Driving Assist

Any one of these features could be linked to the beeping sound, so you can try disabling them (if possible) to see if the beeping noise stops.

“It’s a warning that you are approaching a school, ambulance station, etc. In my area I have to pass 2 schools every time I go out and the beeping is driving me mad. It starts about 300 yards before the school gates and stops at the gates. I appreciate it’s TSS but once I get the beep the warning is over and I want to switch it off – but cannot find out how.” –

6. Seatbelt Alarm & Weight on Seat

The seatbelt alarm is a known suspect for annoying beeps.

There might be a faulty sensor that isn’t recognizing that your seatbelt is fastened.

Alternatively, you may have some weight on the passenger seat like a bag of groceries or your pet pooch which is triggering an alarm.

In this case you can try fastening the passenger seatbelt.

7. Dashcam Beeps

If you have a dashcam equipped, check to make sure it’s not the source of your beeping.

If you hear the beep after going over a bump or a rough patch of road etc. then this is likely the dashcam recording an incident notification.

You will need to adjust the sensitivity and/or volume settings.

Also ensure the SD card is properly inserted.

8. Navigation Alerts

Many mysterious beeps can be attributed to navigation alerts and this is common on many vehicles. You can disable the navigation or the navigation alerts to see if the problem goes away.

9. Faulty latches Or Switches

If you are experiencing beeping whilst driving your CH-R, this may be caused by a faulty door switch or latch, if you have a ‘door ajar’ light on the dashboard then this is almost certainly the case.

Faulty latches are quite common – you may need to have it replaced although you should first try giving all latches a good clean and spraying with something like WD-40.

Similarly, door switches can fail over time – they report the open/closed status of the door and might be sending false readings to the car’s computer.

10. Spare Keys Left in Vehicle

If you’ve left a spare set of keys in your CH-R you may hear a warning beep when you go to lock the vehicle as it thinks you are trying to lock the keys in the car.

11. Phone Alerts

Your phone could be the source of your beeping, especially if it is connected by Bluetooth.

12. Weak 12V Battery

A weak 12V battery can cause a myriad of problems.

To rule this out of the equation, simply have a battery health check performed.

These can be done at AutoZone for free.

Also check to ensure the connections are tight and free of dirt and grime.

13. Parking Brake

If the parking brake is engaged while the vehicle is in motion, the CH-R will try to indicate the driver to release it by beeping.

14. Electronic Devices Inside or Outside of The Car

The beeping may not actually be coming from your CH-R. Do you have any other electronic or battery-powered devices in your vehicle or your garage that could be causing the beeping? Usually, it’s their batteries going bad.

For example, a garage door opener, a smoke alarm, a carbon monoxide detector, or a dropped wristwatch.

15. Headlights ON

An audible warning will sound if you have left the driver door open and the exterior lamps are ON.

16. Phone Alerts

Your phone could be the source of your beeping, especially if it is connected by Bluetooth.

Toyota CH-R Beeping While Driving

If you are experiencing beeping whilst driving your Toyota CH-R, then this is most likely the speed limit warning or speed camera warning which can be disabled in settings under map settings.

It may be caused by a faulty door latch, if you have a ‘door ajar’ light on the dashboard then this is almost certainly the case, these latches can often become stuck.

Faulty latches are very common across all vehicles – you may need to have a latch replaced although you should first try lubricating it with something like WD-40.

If it’s not related to the door switch/latch then it could be caused by a damaged wire or sensor.

A lot of mysterious beeps and electrical issues can be traced back to damaged wires or loose electrical connections.

CH-R Beeps When Exiting Vehicle

If you are hearing a beep or chime when you turn off your CH-R this is likely because you opened the door first without turning off the engine. It may also be caused by if you left the sunroof open.

No Chime:

  1. Engine running
  2. Put vehicle into Park.
  3. Turn off the Engine
  4. Open the door.

Alternative Suggestions

Check for Recalls or TSBs

By entering your car’s VIN number on Toyota’s recall page or the NTHSA’s Safety Issues & Recalls page you can determine whether or not there is a TSB or recall for your vehicle and if there is you’ll want to get it addressed.

A recall is issued by a vehicle manufacturer for issues that are safety-related, while a TSB covers components that may be malfunctioning but don’t compromise the safety of the vehicle.

Watch the Dash Display

This could give you a clue about what’s causing the beeping.

For example, does the beep sound when the ECO light comes on?

Also, keep an eye on the radio / infotainment screen, this might give a clue too.

Disconnect the Battery

Sometimes mysterious beeping problems can disappear with a simple reboot, there are no guarantees here but it’s worth a try.

Disconnect the battery for 20 seconds and this resets many of the electronics in the vehicle.

Check For Warning Messages

When the beeping occurs can you see any lights or warning messages on the instrument panel?

This can give a clue as to what’s causing the beeps e.g. ‘Door Ajar’.

Take it to a Toyota Dealership

If needed, take your Toyota to the dealership.

  • Tell them you are NOT paying for a check on what the problem might be.
  • Ask them if they will check it for free.
  • Most dealerships and other places do quick/initial diagnosis for no money as they plan to make money for the repair of your vehicle.
  • If your unit is still under warranty then they should fix and resolve the issue for free.
