Subaru Tire Pressure Warning Light Indicator On & What To Do
Many of the newer Subaru models come with sensors that will know when your tire pressure is too low or too high. These sensors are attached to a warning light in the dash. This system is called the TPMS or tire pressure monitoring system.
You can find TPMS for Subaru Cars here.
When your warning light comes on, look for a safe place to pull off the road and pull off. Examine all of your tires and look for any visible damage like a nail or other debris that may be stuck in your tire.
Next, look at all your tires and see if they appear to be visibly more deflated than the others.
If you do not see anything, it is time for the listening test.
Move around your car from the tire to the tire and see if you can hear any audible hissing sounds coming from your tires. If you do not hear anything, there is a good chance your tire has just gotten slightly deflated over time, which is normal and happens with weather changes. It is probably safe to drive to a nearby service station and get your tires looked at.

Subaru Tire Pressure Frequently asked Questions
What Affects Tire Pressure in Subaru Cars?
- The most common thing that will change your tire pressure is temperature changes. Summertime heat will make the air in your tires expand, which makes your tire pressure readings higher than in winter.
Cold weather will make your tire pressure drop 1 to 2 psi for every ten degrees that the outside temperature lowers.
2) Another element that will affect your Subaru’s tire pressure is driving frequency and conditions. If you hardly ever drive your car and it is sitting for long periods of time, the tires are likely going to slowly deflate slightly. This is common and happens with almost all tires. You should not leave your car sit for extended periods of time without starting it for other reasons too, it is not good for your engine!
If you have been driving in very rough conditions like off-road or on trails that are not paved, this is likely to have a deflating effect on your tires if you do it very often. The constant beating of the tires on rocks will force small amounts of air to find any possible micro-hole and leave the tires.
How to Keep Your Tire Pressure Gurage Readings in the Correct Range
It is a good idea to purchase a tire pressure gauge no matter what kind of vehicle you have. This way you can always check your pressure no matter where you are. Many new vehicles come with monitoring systems but sometimes the computer may be wrong so always have a tire gauge to make sure your readings are accurate.
When to Check Your Pressure on a Subaru
You should check your tire pressure at least every month. When you are getting gas or when you get home, just take out your gauge and check all 4 tires. This only takes a few minutes and could save your life. Uneven tire pressure can make your steering less reliable and make your response feel squishy, which can make reacting to a dangerous situation unpredictable. This is a good practice no matter what car you have, but especially for Subaru’s.
Why do Some Models Have Different Recommended PSI?
Each car is different and that goes for Subaru as well. Tires are designed to be a certain level based on the weight of the car or truck. As mentioned at the beginning of this guide, most models will be between 32 and 36 psi. However, some are slightly lower or higher and different for front and back tires. This is because the front tires are used for turning and are usually recommended to be slightly harder. Back tires never really turn or need to have a complicated suspension, so they are typically softer (by a couple of psi).
If you go over the list above, you can see almost every model and its corresponding recommended tire pressure. There may be some that are not included, but almost all modern models are represented in that list!
How Does the TPMS Actually Work on A Subaru’s Tires?
When you first start the vehicle, you should see the warning light come on for a few seconds. Do not panic, this is supposed to happen. If it stays on for a longer period of time, you should contact your mechanic or Subaru dealer and find out why.
Each tire pressure sensor has its own separate identification code within the system. When the car starts moving the sensor takes a reading every 30 seconds!
The receiver is located under the carpet near the driver’s side door. This receiver gets the signals from all the sensors and relays the information to the instrument panel in the dashboard. This is attached to the light which will tell you when there is an issue with your tire pressure.
Tips to Inflate Tires Safely
Wait until your tires are cool. Do not inflate when the temperature is extremely high or when you just finished a long trip, the tires will be very hot. It is best to inflate your tires when they are cool and dry, and you are in a safe place like a service station or at home. There is no need to jack up your car just to inflate the tires, you can do this with your car resting on the ground normally.
