Rainy season car care: 5 DIY inspection steps for peace of mind

The stormy rainy season always brings concerns for both drivers and vehicles. Deeply flooded roads and high humidity easily cause severe damage to technical systems.

However, you can proactively prevent risks with simple inspection steps at home. Explore MG’s rainy season car care guide to keep your vehicle running safely.

5 SIMPLE DIY CAR INSPECTION STEPS FOR THE RAINY SEASON

1. Tire grip: The first shield against aquaplaning

Wet roads reduce friction and easily cause dangerous aquaplaning. To ensure optimal water evacuation, tire tread depth should reach 3 mm or more. You can use a dedicated depth gauge or observe the tread wear indicators.

Additionally, maintain standard tire pressure following manufacturer recommendations. Standard pressure specifications are shown on the B-pillar label near the driver’s door.

Periodic tire inspections help vehicles operate safely during rainy and flooded conditions.

2. Wipers and washer fluid: Maintaining clear visibility

Restricted visibility is a leading cause of collisions during heavy rain. Check rubber wiper blades for hardening or smearing across the windshield. Also, refill dedicated washer fluid to wipe away mud and grime easily.

3. Lighting system: Enhancing visibility in the rain

Heavy rain often reduces visibility for all surrounding traffic. Therefore, headlights, taillights, and fog lights must always operate in optimal condition. Regular lighting checks help you spot obstacles clearly and alert vehicles behind.

Versions like MG ZS Lux+ feature automatic headlights and front/rear fog lights to enhance safety in low visibility.

4. Brake responsiveness: Critical on slippery roads

Rainwater on brake discs can reduce stopping power and lengthen braking distances. You can open the bonnet to visually inspect the translucent brake fluid reservoir. Standard fluid levels must remain stably between the MIN and MAX marks.

Avoid opening the reservoir cap to prevent humid air from degrading fluid quality. If fluid falls below MIN or darkens, have the car inspected immediately.

Listen for squealing noises or an unusually spongy brake pedal feeling. If abnormal symptoms appear, take your vehicle to a service workshop promptly.

5. Battery and engine bay: Preventing moisture and short circuits

High air humidity during rainy seasons easily oxidizes battery terminals. Clean electrical contact points and inspect wiring to prevent electrical leakage. This helps the vehicle start reliably and keeps electronic components running smoothly.

SAFETY RECOMMENDATIONS FOR DRIVING THROUGH FLOODED AREAS

Hydro-locking can cause severe engine damage if handled improperly. To protect vehicles, MG technical experts recommend the following crucial guidelines:

  • Assess water levels: Do not drive through water exceeding half the wheel height.
  • Maintain steady speed: Shift to low gear, keep steady throttle, and avoid sudden acceleration.
  • Turn off AC: Reduce engine load and prevent fans from pulling water into the engine bay.
  • Stalled engine handling: Never restart the engine while stalled in flooded water.
Proactively contact rescue services immediately when encountering flooding incidents.

In this situation, keep the vehicle as is and contact emergency rescue services immediately.

WARNING SIGNS REQUIRING IMMEDIATE SERVICE VISITS

DIY inspections at home help you detect abnormal vehicle symptoms early. However, if the following conditions occur, bring your car to an MG Care center:

  • Engine check, ABS, or battery warning lights staying illuminated on the dashboard.
  • Strange engine knocking noises or heavy vehicle vibrations during wet acceleration.
  • Water ingress detected in the cabin floor or engine bay after deep wading.
  • Steering wheel misalignment or abnormal heaviness, hindering control on wet roads.

Here, technicians apply standard MG Care procedures to resolve all issues completely.

Professional servicing at MG Care workshops provides comprehensive protection for your car.
