What does the check fuel fill inlet warning mean in the message center?
ANSWER : Today’s cars have very comprehensive emissions monitoring systems. Not only does the computer monitor the engine and the exhaust, but it also monitors your fuel system. If it detects an evaporative emissions leak (gas), it may display a warning in your message center that reads “Check fuel fill inlet”. This is the same thing as a “loose gas cap” warning in other cars, except that your car doesn’t have a gas cap. Here’s what to do:

Check the fuel filler door to make sure it’s closed.
Check the fuel filler inlet to make sure that it sealed correctly.

Tip

If the message doesn’t clear after taking these steps or reappears, have the car inspected.

What does the park brake engaged warning mean in the message center?
ANSWER : Your car’s message center can provide you with a lot of important information about the various systems on your car, their condition, and more. If you see a warning message that says “Park brake engaged,” it most likely means that you need to release the parking brake before driving.

If the light stays on after you release the parking brake, there is a problem in the system. This could be an electrical problem with the parking brake switch circuit, or it could be a problem with the brake hydraulic system, such as low brake fluid level or a leak. In either case, it’s important to have the vehicle inspected by a professional as soon as possible. In many cases, it is not safe to drive with the parking brake light on.

Tips:

This warning will only be shown if the parking brake is on, the engine’s running and you’re driving more than 3 MPH.
If the warning doesn’t clear after releasing the parking brake, have your car inspected.

What do the various “door ajar” warnings mean in the message center?
ANSWER : The “door ajar” warnings in the message center could indicate a number of things. Usually the door ajar warnings are an indication that one or more of the vehicle doors are open. However, there are some cases when this is an indication of another problem.

Each door has a switch inside the latch of the door and there may be up to five (5) door ajar switches for a vehicle:

Driver’s side door ajar switch
Passenger’s side door ajar switch
Right rear door ajar switch
Left rear door ajar switch
Rear latch/trunk door ajar switch

After checking to make sure that all of the vehicle doors have been shut properly and there isn’t anything obstructing the door or trunk, check to see if the door ajar indicator lights have turned off in the message center. If they have not, there are several possibilities that could explain this:

The Door Ajar Warning Indicator Light dimmer needs to be adjusted
The door ajar switch is stuck and needs to be lubricated
A fuse box relay for the interior lights needs to be replaced
A faulty door ajar switch needs to be replaced

If your Door Ajar Warning Light is on in the message center and you need assistance determining why it will not go off, it would be a great idea to have the door diagnosed by a certified technician, such as one from YourMechanic.

What does the service AdvanceTrac® warning mean in the message center?
ANSWER : AvanceTrac is the electronic stability control (ESC) system used in Ford vehicles. It may also be referred to as “traction control” or “vehicle dynamic control” is other vehicle models. This system monitors the steering stability of the vehicle and engages when skidding has been detected, or the loss of traction.

The AdvanceTrac system counteracts oversteering and understeering by reducing power and/or applying brakes to specific wheels. This is done by the use of electronic sensors that communicate with the Powertrain Control Module (PCM) regarding steering performance and stability in adverse weather conditions. The are several components that are necessary for the AdvanceTrac system to work properly.

Anti-Lock Brake System-When/if the brakes lock up, this may cause a loss of control and the vehicle may slide. The anti-lock brake system prevents this from happening by preventing the brakes from locking up, as well as preventing oversteering and/or understeering when the vehicle starts to slide.

Traction Control System-The traction control system works by reducing engine speed and determining which wheel to apply brake pressure to in order to prevent the vehicle from sliding.

Electronic Sensors-The Powertrain Control Module (PCM) receives information from electronic sensors regarding the rotational speed of each wheel, the horizontal motion of the vehicle, and the vertical motion of the vehicle.

If the “service AdvanceTrac” warning indicator light comes on in the dashboard, this could be an indication of several issues.

A faulty wheel-speed sensor
A faulty steering-angle sensor
A faulty rotational-speed sensor
An issue with the steering rack
Something that is lodged in one of the wheels
The AdvanceTrac system needs to be reprogrammed

If you need assistance diagnosing the service AdvanceTrac warning light, contact a certified techncian for help.

What does it mean if the “Service power steering” warning is displayed in the message center?
ANSWER : Your car’s Power Steering system is an integral part of the vehicle. While the system can fail and you’ll still have the ability to steer, you’ll find that the wheel is much harder to turn. Obviously, it’s important to have the system serviced and maintained properly. If you see a warning in the message center that reads, “Service power steering,” it means that there’s a condition that has been detected requiring immediate service. Have your car inspected immediately.

Tip

If you see the “Service power steering NOW” warning, you need to take your vehicle immediately to a mechanic.

What does it mean if the message center shows the warning “engine oil change soon?”
ANSWER : It’s absolutely essential that you keep up with normal maintenance, like oil changes, tire rotations, air filter changes and the rest. Your car is designed with a reminder system designed to help make keeping your car serviced easier. If you see the warning message “Engine oil change soon” in the message center of your car, it means that the engine oil life is now between 10% and 0%. Have the oil changed and then make sure to reset your oil life in the car’s computer.

What does the “Brake fluid level low” warning in the message center mean?
ANSWER : Your car is equipped with some pretty advanced equipment in order to monitor the various systems needed for safe driving. One of those sensors is designed to check the level of fluid in the master cylinder reservoir. If the fluid gets low, the car will show a warning in the message center that reads “Brake fluid level low.” You’ll need to open the hood and check the level of fluid in the reservoir. If it’s low, it will need to be topped off. If you notice that it goes low again after you have topped it up, you may have a leak and should get the brake system inspected.
