Renault Warning Lights: Compare Audi, Škoda, VW and BMW

Published

Short answer: Symbol Index has no verified Renault meanings yet, so your Renault owner's handbook is the authority for your car. For comparison, Audi, Škoda and Volkswagen sources describe the ABS light as a fault. BMW and Audi sources describe the airbag light as a fault. All four brands describe a brake pad light for worn pads, and BMW says its charging light means the battery is not charging properly.[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Does Symbol Index cover Renault warning lights?

Not yet. None of the verified sources behind this guide come from Renault, so we cannot tell you what any light means on a Renault. Check the warning light section of your own Renault owner's handbook for the exact meaning and what to do.

What we can share is how other carmakers' manuals and guides describe symbols that look similar. Treat these as comparisons only. Each meaning below applies to the brand named, and Renault may use a different color, symbol or instruction.

Red and amber warning triangles on other brands

Several brands use a triangle as a central warning that works alongside a message or a second symbol. The triangle itself usually points you to that message rather than naming a specific part.[11, 12, 13]

  • Central warning (red triangle) symbolRed central warning triangle on Audi cars: it draws attention to an urgent message and does not identify a component on its own. Read the message or second symbol straight away and follow its instruction.[12]
  • Central warning (red triangle) symbolRed triangle on Škoda cars: a central warning for a serious hazard, alone or with another red light, normally with a message in the instrument cluster.[13]
  • Central warning (red triangle) symbolRed triangle on Volkswagen cars: a priority 1 warning. Do not drive on; stop when safe, check the fault shown and get expert help as soon as possible.[14]
  • Central warning (amber triangle) symbolAmber warning triangle on Škoda cars: a central warning that lights alone or with another amber light, with a cluster message explaining the cause.[11]
  • Central warning (amber triangle) symbolYellow triangle on Volkswagen cars: a priority 2 warning. Check the fault soon and have it checked by a workshop.[15]

ABS, brake and brake pad warning lights

Brake-related lights on other brands come in a few versions: an ABS light, a general brake system warning and a brake pad wear light. Each brand describes them differently, so match the symbol in your Renault handbook before acting.[2, 3, 8, 16]

  • ABS warning symbolABS warning on Volkswagen cars: lit yellow, ABS has failed or has a fault. The brakes still work, but without ABS; drive carefully and have it checked.[3]
  • ABS warning symbolABS warning on Škoda cars: continue driving carefully and seek a specialist garage. If the red brake light comes on with it, there is a fault in the brake system and ABS, so do not continue driving.[2]
  • ABS warning symbolABS warning on Audi cars: ordinary braking usually still works, but ABS will not step in, and stability functions that depend on it can be affected. Leave more braking distance and have the car checked soon.[1]
  • Brake warning (BRAKE) symbolBrake warning (BRAKE) on European Audis: the word BRAKE warns of a problem with the basic brake system. If the parking brake is released, stop as soon as it is safe and contact a workshop.[16]
  • Brake pad wear warning symbolBrake pad wear warning on Škoda cars: the pads have worn down to their limit. Drive with extra care to a specialist garage and have them replaced.[8]
  • Brake pad wear warning symbolBrake pad wear on Volkswagen cars: it lights yellow when the pads are worn. Go to a workshop straight away to have all pads checked and replaced if necessary.[9]
  • Brake pad wear warning symbolBrake pad wear on Audi cars: have the brakes inspected soon, before worn pads damage the discs. The light does not show how much is left on each pad.[7]

Airbag warning lights

An airbag light on the brands below signals a possible problem with the restraint system, which can mean reduced occupant protection. Your Renault handbook will say what its own airbag symbol means.[17, 4]

  • Airbag warning symbolAirbag warning on BMW cars: shown in orange or red, the airbags may not deploy properly in an accident. Have the system checked as soon as possible.[4]
  • Airbag / restraint system warning (amber) symbolAirbag / restraint system warning on Audi cars: occupant protection could be reduced. Have it inspected promptly with suitable diagnostic equipment, and do not unplug seat or airbag wiring to make the light go out.[17]
  • Airbag fault (AIR BAG) symbolAIR BAG text warning on Audi cars: one of the airbags has failed, and only a dealer or authorized workshop can repair it.[18]
  • Airbag / belt tensioner fault (amber seated occupant) symbolAirbag / belt tensioner fault on Volkswagen cars: lit continuously yellow means a fault in the airbag or belt tensioner system, so have it checked straight away. It also lights briefly at ignition on as a function check.[19]
  • Airbag fault warning symbolAirbag fault warning on Škoda cars: lit with the passenger airbag OFF light in the overhead panel, the airbag switch is faulty and the passenger airbag will not deploy in an accident. Have it checked immediately.[20]

Battery and charging warning lights

Battery symbols on other brands usually come with a message, and the message changes what you should do. For Audi cars, the advice is to read the message and act on it.[21, 22]

  • Charging / battery warning symbolCharging / battery warning on BMW cars: the battery is not being charged properly. Have the charging system checked by a workshop soon.[10]
  • Charging / battery warning symbolRed battery light on Volkswagen cars: lit with a message, the 12-volt system may fail. Do not drive on; stop safely, switch off unnecessary consumers and the ignition, and get expert help.[23]
  • Charging / battery warning symbolRed battery light on Škoda cars: with a message that the 12V battery is not charging, park safely, switch off the engine and ignition, and get help from a specialist garage.[24]
  • Battery / charging warning (amber) symbolAmber battery light on Škoda cars: with a weak or discharged 12V battery message, drive several kilometers or use a charger; with a not-charging or fault message, seek a garage.[22]
  • Battery / charging warning (amber) symbolAmber battery light on Audi cars: it can mean the charge is low and driving will recharge it, but it can also warn that the engine may not restart if switched off.[21]

Other warning lights people ask about

  • AdBlue warning symbolAdBlue warning on Audi cars: AdBlue needs topping up or the system has a fault, and a distance countdown may appear. Act before any no-restart countdown reaches zero.[25]
  • AdBlue level low, bottle (red) symbolRed AdBlue bottle on Volkswagen cars: the level is too low and the engine cannot be restarted. Park and add at least the minimum quantity of AdBlue.[26]
  • Check fuel cap symbolCheck fuel cap on Audi cars: the cap is not closed properly. Stop somewhere safe and tighten it until it clicks, or the engine warning may come on next.[27]
  • Bonnet not closed symbolBonnet not closed on Audi cars: the bonnet is not shut or the latch sensor cannot confirm it. Pull over and shut it firmly; never keep driving while it might fly up.[28]
  • All-wheel drive fault symbolAll-wheel drive fault on Škoda cars: switch off the engine, wait about 10 minutes and restart. If the light stays on after a short drive, seek a specialist garage.[29]
  • Auto Start/Stop fault symbolAuto Start/Stop fault on BMW cars: the Stop/Start system is malfunctioning and needs attention at a workshop.[30]

Frequently asked questions

Is it safe to drive a Renault with the ABS light on?
Our verified sources do not cover Renault, so check your Renault handbook. For comparison, on Volkswagen cars the brakes still work without ABS, while on Škoda cars a red brake light together with the ABS light means do not continue driving.[2, 3]
What does a red triangle warning light mean?
We have no verified Renault meaning for it. On Volkswagen cars the red triangle is a priority 1 warning that means stop when safe, and on Audi cars it draws attention to an urgent message shown with it.[12, 14]
Why does the airbag light flash after starting the car?
Check your Renault handbook, as we cannot confirm Renault's behavior. On Volkswagen and Škoda cars, lighting for about 4 seconds and then flashing for about 12 seconds means the airbag or belt tensioner was deactivated with a diagnostic tool.[19, 20]
Can a low AdBlue warning stop the engine from starting?
On Volkswagen cars, yes: the red AdBlue warning means the engine cannot be restarted until you add at least the minimum quantity. For a Renault, check your owner's handbook.[26]
