Eco-driving, tyres & dashboard warnings

Read warning lights by urgency, drive economically, decode tyre markings, use winter equipment correctly and protect the engine on difficult journeys.

English dashboard visuals, memory cards and a fixed 20-question test with five choices
Decision overview

Treat warnings according to urgency

01
RecognisePersistent red critical-system warning
InterpretStop safely and follow the handbook

Oil pressure, overheating or brake faults can require immediate action.

02
RecogniseAmber warning
InterpretCheck promptly; adjust your driving

A flashing or severe warning can require a more urgent response.

03
RecogniseGreen indicator / blue headlamp symbol
InterpretA function is operating

Green arrows are indicators; blue identifies main-beam headlights.

Part 1

Dashboard colours tell you how urgently to respond

🔴 RED · STOP AS SOON AS SAFE🟠 AMBER · CHECK SOON🔵 GREEN / BLUE · STATUS
Oil pressure

Stop safely and switch off the engine.

Battery charge

Charging-system fault: stop and assess safely.

Brake system

Check the parking brake and stop if a fault may exist.

Engine temperature

Stop safely; allow the engine to cool and follow the handbook.

Tyre pressure

Check tyre condition and pressures promptly.

ABS / stability

Assistance may be unavailable; arrange diagnosis.

Low fuel

Refuel soon—do not plan on the warning reserve.

Turn indicators

Green arrows flash to show your direction indicators are active.

Blue main-beam dashboard tell-tale
Main-beam indicator

The blue headlamp symbol means main-beam headlights are on. Dip in time to avoid dazzling other road users.

Part 2

Smooth decisions save more than abrupt corrections

HabitBetter choiceWhy
🌱AccelerationBuild speed smoothly and anticipate.Avoids unnecessary fuel demand.
🛞Gear choiceUse the highest suitable gear without labouring the engine.Keeps engine speed efficient.
❄️Traditional shift cuePetrol ≈ 2,500 rpm; diesel ≈ 2,000 rpm.Approximation only—follow the vehicle.
🛢️Windows at speedClose them when practical.Reduces aerodynamic drag.
⛰️Air conditioningUse only as needed.Places an additional load on the engine.
🌱Long waitSwitch off when safe, legal and appropriate.Avoids unnecessary idling.
Part 3

Tyre markings are a compact specification

165/70R1481T
CodeMeaningCheck
🌱165Nominal width in millimetresCorrect approved size
🛞70Aspect ratio: sidewall height as % of widthCorrect profile
❄️RRadial constructionConstruction type
🛢️14Rim diameter in inchesWheel compatibility
⛰️81Load indexAdequate for the vehicle/load
🌱TSpeed indexMeets the required specification
Part 4

Winter equipment must match the road and the destination

Winter tyres

Not generally compulsory nationwide in Belgium, but recommended in cold conditions and possibly required abroad.

Studded tyres

Seasonal, fitment and speed restrictions apply. Verify current rules before use.

Snow chains on dry asphalt

Do not use them without snow or ice coverage.

Part 5

ABS and engine braking: keep control without overheating

ABS

Firm pressure—do not pump

Brake firmly and keep pressure applied. Steer only where space and grip allow.

Maintain firm brake pressure
Do not pump manually
⛰️

Choose a lower gear early

Use engine braking on a long descent. If brakes fail, use an escape lane where available.

Select the gear before descent
Never coast in neutral
Part 6

Oil protects the engine; LEZ rules protect city air

TopicCorrect actionImportant detail
🌱Engine oilCheck on level ground using the vehicle procedure.Let oil settle; keep within MIN and MAX.
🛞Before a long tripCheck oil, coolant, tyres and lights.Do not overfill above MAX.
❄️Low-emission zoneCheck the official city portal before entry.Euro standard, registration and exemptions matter.
🛢️Belgian LEZ citiesBrussels, Antwerp and Ghent operate schemes.Rules are city-specific and can change.
Part 7

Disabled vehicles, advertising and poisonous exhaust gas

SituationRule to studySafe interpretation
🌱Disabled vehicle on a public roadRemove it as soon as possible; the study maximum is 24 hours.Never leave it where stopping is dangerous or prohibited.
🛞Vehicle used principally for advertisingStudy maximum: 3 hours on the public road.Local restrictions can be stricter.
❄️Vehicle displayed for saleDo not use the public road as a sales display.Use authorised private premises.
🛢️Carbon monoxideColourless, odourless and highly poisonous.Never run an engine in an enclosed space.
⛰️Engine idlingSwitch off during a longer wait when safe and lawful.The 30-second cue is an eco tip, not permission to ignore traffic needs.
Part 8

Tyre care and skid response

CheckCorrect approachAvoid
🌱Tyre rotationFollow the vehicle/tyre maker’s pattern and interval.A universal 10,000–15,000 km rule for every vehicle.
🛞Wheel boltsTighten in the specified crosswise sequence and torque.Guessing the torque.
❄️Rear-wheel skidEase off smoothly and steer toward the slide.Harsh braking or opposite lock.
🛢️Front-wheel understeerEase off and reduce steering demand until grip returns.Turning more sharply.
⛰️ABS emergency stopBrake firmly and hold.Pumping the pedal.
