Warning lights and driver messages
Warning lights and driver messages
Engine, lubrication and cooling
EPC – petrol engine management
Yellow / amber · Warning · Steady
Meaning
The petrol engine management system has detected a fault. EPC does not identify a particular failed component.
Recommended action
Arrange engine inspection promptly. Brief illumination with the ignition on is a check; the lamp should go out after starting.
Key indication
This is an example of an indication. Check its meaning for your specific model and equipment against the exact message and your vehicle’s owner’s manual.
Emissions system – MIL steadily lit
Yellow / amber · Warning · Steady
Meaning
An emissions system fault has been detected. The symbol alone does not identify a failed component.
Recommended action
Reduce load and arrange inspection as directed by the manual and message. If running is abnormal, other warnings appear or STOP is displayed, stop safely and seek assistance.
Key indication
This is an example of an indication. Check its meaning for your specific model and equipment against the exact message and your vehicle’s owner’s manual.
Glow plug lamp – preheating before starting
Yellow / amber · Operating information · Steady
Meaning
On a diesel engine it lights during preheating. This normal state before starting is not itself a fault.
Recommended action
Wait for the lamp to go out before starting, as instructed in the vehicle’s manual.
Key indication
This is an example of an indication. Check its meaning for your specific model and equipment against the exact message and your vehicle’s owner’s manual.
Combustion engine cooling system
Red · Warning · Steady illumination
Meaning
May indicate overheating, an incorrect coolant level or a cooling system fault.
Recommended action
Stop safely, switch off the engine and follow the vehicle message. Check coolant as instructed only after safe cooling. Do not open a hot expansion tank.
Key indication
Visible coolant in the reservoir does not by itself resolve the warning. This entry does not cover electric-drive cooling.
Diesel particulate filter – DPF
Yellow / amber · Warning · Steady illumination
Meaning
On relevant diesel versions it indicates accumulated soot and a need for filter regeneration.
Recommended action
Check regeneration driving conditions in your specific manual. If other warnings appear or engine operation is abnormal, do not follow a universal internet regeneration procedure.
Key indication
No single speed, duration or engine speed applies to all engines. Petrol GPF/OPF requires separate verification.
Engine oil pressure – flashing red warning
Red · Warning · Flashing
Meaning
A flashing red symbol with an oil-pressure fault message warns of inadequate lubrication. A correct oil level does not prove correct pressure.
Recommended action
Stop safely and switch off the engine. Do not leave it running. Any restart must explicitly follow the instructions for the specific vehicle; obtain professional assistance if uncertain.
Key indication
Follow the exact message and your vehicle’s manual. The general guide does not document every model variant.
Brakes and stability systems
Electromechanical brake servo not working · multiple meanings of the same symbol
Electromechanical brake servo not working
Red · Warning · Steady
Meaning
Brake assistance is not working. More pedal force is required and stopping distances increase.
Recommended action
Stop safely, applying greater brake pedal force as required. Do not continue driving; obtain professional assistance immediately.
Key indication
This is an example of an indication. Check its meaning for your specific model and equipment against the exact message and your vehicle’s owner’s manual.
Brake system
Red · Warning
Meaning
Depending on the version, the symbol may relate to an applied parking brake, low brake fluid or a brake system fault.
Recommended action
The exact symbol and message are decisive. If the warning remains after releasing the parking brake or the vehicle reports a brake fault, stop safely and obtain professional assistance.
Key indication
Topping up brake fluid does not repair the cause of its loss. Distinguish a fault warning from the normal parking brake indication.
Brake pad wear
Yellow / amber · Warning · Steady
Meaning
The system indicates that the brake pads require inspection.
Recommended action
Arrange prompt professional brake inspection and pad replacement as required. The lamp does not indicate how many kilometres remain before replacement.
Key indication
This is an example of an indication. Check its meaning for your specific model and equipment against the exact message and your vehicle’s owner’s manual.
ABS fault
Yellow / amber · Warning · Steady
Meaning
The anti-lock braking system is not working correctly or is unavailable. Normal braking may remain available without ABS protection.
Recommended action
Arrange professional inspection promptly. If a red brake warning or STOP instruction also appears, stop safely and follow the exact message.
Key indication
This is an example of an indication. Check its meaning for your specific model and equipment against the exact message and your vehicle’s owner’s manual.
ESC / TCS intervention · multiple meanings of the same symbol
ESC / TCS intervention
Yellow / amber · Operating information · Flashing
Meaning
Flashing indicates that stability or traction control is intervening. It does not by itself indicate a fault.
Recommended action
Adapt speed and driving style to available grip and traffic conditions. The system cannot overcome physical limits.
Key indication
This is an example of an indication. Check its meaning for your specific model and equipment against the exact message and your vehicle’s owner’s manual.
ESC fault or system-induced deactivation
Yellow / amber · Warning · Steady
Meaning
A lamp that stays on after the initial check may indicate a fault or system-induced deactivation. This differs from flashing during intervention.
Recommended action
Read the message and follow the cited manual. If the lamp remains on, arrange professional inspection; do not rely on stability control being available.
Key indication
This is an example of an indication. Check its meaning for your specific model and equipment against the exact message and your vehicle’s owner’s manual.
Brake servo – restricted operation, amber warning
Yellow / amber · Warning · Steady
Meaning
With the documented amber warning, electromechanical braking assistance is restricted. Pedal pulsations may occur and stopping distance can increase.
Recommended action
Allow for greater brake-pedal effort and seek professional service. Other simultaneous messages, including STOP, take priority; amber is not universal assurance that continued travel is safe.
Key indication
Different from red servo failure with the instruction not to continue. In another message the same sign can refer to another brake component; exact text and cited edition are decisive.
ASR – traction control manually off (Caddy)
Yellow / amber · Operating information · Steady
Meaning
On this Caddy, the steady amber skidding-car OFF sign confirms manual ASR deactivation. Not automatically a fault or complete deactivation of every stability function.
Recommended action
Keep ASR enabled in normal conditions. Follow the manual when switching it off for loose surfaces or freeing a stuck vehicle. Re-enable ASR once that situation has passed.
Key indication
Not the plain symbol flashing during ASR/ESC intervention. Control is in infotainment ESC settings; menu name alone does not establish that all ESC functions are off.

Meaning
In this guide, flashing can relate to a strained steering column or a column that has not unlocked or locked.
Recommended action
Follow the exact message and manual; obtain professional assistance if the steering cannot be safely unlocked.
Key indication
Follow the exact message and your vehicle’s manual. The general guide does not document every model variant.

Red · Warning · Steady
Meaning

Recommended action
Take control of speed immediately and brake as necessary. Do not wait for ACC to resolve the danger by itself.
Key indication
This is an example of an indication. Check its meaning for your specific model and equipment against the exact message and your vehicle’s owner’s manual.
Take-over steering request
White · Information / warning depending on state · Steady
Meaning
The vehicle asks the driver to take over steering. This does not confirm that the system can handle the situation independently.

Unsure what an indicator means?
When contacting the workshop, tell us the model, production year, powertrain and exact message. A photograph of the entire instrument cluster message and whether the lamp is steady or flashing will help. Take photographs only with the vehicle safely parked.
