alarm info
SECURITY ALARM SYSTEM — IF EQUIPPED
This system monitors the vehicle doors, liftgate, liftgate flipper glass, and ignition for unauthorized operation. When the alarm is activated, the system provides both audible and visual signals. The horn will sound repeatedly for three minutes and the headlights and taillights will flash for an additional 15 minutes.
To Set the Alarm
The alarm will set when you use the remote keyless entry transmitter to lock the doors and liftgate or when you use the power door lock switch while the door is open. After all the doors are locked and closed, a red light on top of the instrument panel will flash rapidly for about 16 seconds to signal that the system is arming. During this 16 second pre-arm period, opening any door or the liftgate will cancel the arming. If the system successfully arms, the red light will flash at a slower rate to indicate the alarm is set.
To Disarm the System
To disarm the system, use the remote keyless entry transmitter or the key to unlock the driver’s door. If something has triggered the system in your absence, the horn will sound three times when you unlock the doors. Check the vehicle for tampering.
The Security Alarm System is designed to protect your vehicle; however, you can create conditions where the system will arm unexpectedly. If you remain in the vehicle and lock the doors with the transmitter, once the system is armed (after 16 seconds), when you pull the door handle to exit the alarm will sound. If this occurs, press the “Unlock” button on the remote keyless entry transmitter to disarm the system. You may also accidentally disarm the system by unlocking the driver’s door with the key and then locking it. The door will be locked but the Security Alarm will not arm.

over inflation almost never causes tire failure
Bill Woehrle tire engineer, and now runs a company called TFI: Tire Forensics Investigation
Bill says that overinflation almost never causes tire failure. The standard tire is inflated to about 30 to 35 pounds per square inch. Under hot weather and highway conditions, the temperature of the air inside the tire rises about 50 degrees. That increases the pressure inside the tire about 5 psi. The burst pressure of a tire is about 200 psi.
Bill says that the most vulnerable part of any steel-belted radial tire is where the steel belts are attached to the rubber near the edges of the tread, also called the “shoulders” of the tire. If the tire is not abused, those belts should stay attached to the rubber for the entire tread life of the tire.
But if the tire is defective (see Firestone debacle) at the end of its useful life, or if the tire has been abused in some way, the top belt can separate. When it tears, it tears violently, so it’s a crapshoot as to whether the next layer of rubber will tear too and cause a blowout. And the most common form of abuse is underinflating your tires. That’s right, UNDERinflating them.
Woehrle says that underinflating the tire puts additional stress on the tire’s shoulders, where the belts are attached. And if a tire is underinflated by 10 or 15 psi, the temperature at those shoulders can reach 200 degrees. So you’ve got a vulnerable part of the rubber that’s hot being stretched and pulled, and that’s a recipe for tire failure.
By the way, overloading the car with say, luggage or two mothers-in-law does the same thing as underinflating the tires. It stresses the shoulders of the tires.
So Bill says if you’re going to make a mistake in inflating your tires, it’s much better to overinflate them a bit than underinflate them. There are really no horrible ramifications of overinflating the tires by 10 or 15 psi, except that when you go over bumps you’ll bounce up and hit your head on the dome light.
But the dangers of underinflation are catastrophic tire failure. So for all of our readers: Make sure your tires have sufficient tread and have not exceeded the manufacturer’s mileage rating. Make sure they’re less than 10 years old, even if they have low miles (because old rubber gets brittle and has a greater tendency to crack). And check your tire pressure at least once a month to make sure your tires aren’t underinflated.

How do you reset the TPMS on a Jeep JK?
Locate the TPMS reset button under the steering wheel and press in, holding until the tire pressure light blinks three times. Start the car and wait 20 minutes for the sensor to refresh. Inflate all tires to 3 PSI over their recommended amount, then deflate them completely.
Tire Pressure Monitoring System (TPMS)
Sometimes even after inflating your tires the tire pressure light remains on. It’s important to reset this light so that your tire pressure monitoring system (TPMS) can keep you alert and aware of possible issues with your wheels.
Resetting Your Tire Pressure Light
While the tire pressure light should turn off on its own after properly inflating your tires, there are additional steps available for a reset if needed:
- For about 10 minutes, drive at or above 50 mph. The next time you restart your car, it’s likely the sensor will reset.
- Turn the key to the “On” position, but don’t start the car. Locate the TPMS reset button under the steering wheel and press in, holding until the tire pressure light blinks three times. Start the car and wait 20 minutes for the sensor to refresh.
- Inflate all tires to 3 PSI over their recommended amount, then deflate them completely. Be sure to include the spare tire, as it may have a sensor as well. Once they’re all deflated, re-inflate to the recommended tire pressure.
- With the vehicle off, use a wrench to disconnect the positive battery cable. Turn the car on and honk the horn for about three seconds. This will discharge any power still stored in the vehicle. Then reconnect the battery.
If your TPMS light is still on, you should definitely bring it in for a diagnosis.
