Ford C-Max ABS Dashboard Warning Light
ABS
Warning light name: Ford C-Max ABS warning light.
Description: ABS stands for 'anti-lock braking system' and is an additional safety feature that allows the driver to steer under heavy braking. In some instances, ABS also helps to reduce stopping distances. If ABS fails, the amber ABS warning light remains permanently lit, however normal brakes will continue to operate as usual. Be cautious as heavy use of the brake pedal will increase the risk of locking wheels. Failure of the ABS is usually due to the sensors and/or wiring located on each wheel.
Ford C-Max Brake Dashboard Warning Light
Brake
Warning light name: Ford C-Max brake warning light.
Description: The red exclamation mark in a circle symbol indicates a brake issue. These are the possible conditions to cause the brake warning light to come on:
Parking brake: Make sure the parking is fully disengaged.
Brake fluid: If the parking brake is properly released, the next check should be the brake fluid level. Locate the brake fluid reservoir under the hood and check levels fall between the MIN. and MAX. markers on the tank. Use Ford DOT 4 brake fluid. If the pedal feels spongy, it may indicate a leak in the brake system. In this instance, do not continue driving.
Brake fault: If the parking brake is fully released and the brake fluid levels are adequate, it then means there's a fault with the brake system. It's advised to have your brake system services immediately by a Ford workshop.
Ford C-Max Airbag Dashboard Warning Light
Airbag
Warning light name: Ford C-Max airbag warning light.

Wiring / connection: Part of the wiring and connections can be found under the driver and/or passenger seats. Objects getting lodged can cause wiring to disconnect or become lose.
Sensors: There are various sensors that can trigger the airbag warning light. This includes the passenger seat belt occupancy sensor and impact sensors. The sensor in the seat belt buckle could be defective or obscured by an object that's gotten lodged causing a false warning light.
Ford C-Max Read to Drive Dashboard Warning Light

Ford C-Max Check Engine Dashboard Warning Light
Check Engine
Warning light name: Ford C-Max check engine warning light.
Description: The Ford C-Max check engine warning light is linked to the onboard diagnostics system and as a generic warning, it can light up for various reasons. The only effective way to locate the fault is to use diagnostic equipment which connects to the vehicle to read fault codes. Some of the common faults that trigger the check engine warning light are:
Oxygen sensor: This sensor is responsible for detecting the levels of unburnt oxygen in the fuel system. A faulty oxygen sensor can trigger the check engine light and result in poor fuel economy. Continued driving with a bad oxygen sensor may result in catalytic converter and/ or engine damage.
Mass airflow (MAF) sensor: This sensor is responsible for detecting the amount of air entering the engine. A faulty MAF can result in poor engine performance, poor fuel economy and eventually engine damage.
Fuel cap: An incorrectly fitted fuel cap alters the pressure inside the fuel tank triggering the check engine light.
Spark plugs: Ageing and misfiring spark plugs can cause an engine misfire that may result in catalytic converter and engine damage.
What to do if the check engine light comes on
If the check engine warning light comes on in your Ford C-Max, avoid hard acceleration and high speeds. You can continue driving, but have diagnostics as soon as possible. If the check engine light is flashing, it usually indicates a misfiring engine which may result in damage. In this instance, avoid heavy engine loads, keep the speed and revs low. Have engine checked as soon as possible.
Ford C-Max Battery Dashboard Warning Light
Battery
Warning light name: Ford C-Max battery warning light.

Battery charge is being drained and when the charge is exhausted, it's likely the engine will stop. Immediately switch off any electrical vehicle utilities that are not essential. This could be heating, A/C, demisters, radio etc. This will help to preserve battery power. If you're on a highway, come off and make your way immediately to the nearest auto repair workshop. Usual cause of battery warning light is:

A flashing glow plugs light means there's a fault. The fault could mean the glow plugs require replacement but would require diagnostic equipment to read fault codes.
Ford C-Max Oil Pressure Dashboard Warning Light
Oil Pressure
Warning light name: Ford C-Max oil pressure warning light.
Description: This red warning light is one of the most critical due to the potential engine damage involved. If this low oil pressure warning light comes on the dash when driving, safely pull off the road as soon as possible and switch off the engine.
1. The low oil pressure warning light isn't an indication of low oil level. However, low oil levels can trigger low pressure. After leaving the engine off for a few minutes (to let the oil settle in the engine), check the oil level using the dipstick. If the level is under the MIN mark, top up with oil.
2. After topping up, check that the engine warning light has gone off. If it's still on, do not continue driving. In this instance, the engine may not receive sufficient lubrication resulting in damage. Arrange to have your vehicle towed.
