If a warning light suddenly appears on your dashboard while driving through Westport, Fairfield County, or on I-95, it can be stressful - especially if you're not sure what it means. Modern Lexus vehicles are designed with advanced technology that alerts drivers when something needs attention, from low tire pressure to more serious engine concerns.

At Lexus of Westport, we help Connecticut drivers keep their vehicles performing at their best. Here's a guide to some of the most common Lexus warning lights and what you should do if they appear.

Check Engine Light

One of the most recognized dashboard indicators is the check engine light. In most Lexus vehicles, this appears as an engine-shaped icon.

What it could mean:

• Loose or damaged gas cap

• Engine misfire

• Emissions system issue

• Sensor malfunction

What to do:

If the light is solid, schedule service soon to diagnose the issue. If the light is flashing, reduce speed and have your Lexus inspected immediately, as this can indicate a serious engine problem.

Tire Pressure Warning Light

This warning light looks like a horseshoe-shaped tire with an exclamation point in the center.

Common causes:

• Low tire pressure from temperature changes

• Slow tire leak

• Seasonal Connecticut weather fluctuations

Cold weather in Connecticut commonly causes tire pressure to drop, especially during winter months.

What to do:

Check your tire pressures and inflate them to the manufacturer's recommended PSI. If the light stays on, your vehicle may have a puncture or TPMS sensor issue.

Battery Warning Light

The battery light typically appears as a small battery icon.

Possible causes:

• Weak battery

• Failing alternator

• Charging system issue

What to do:

Your Lexus may continue driving temporarily, but the battery may stop charging. Schedule service as soon as possible to avoid getting stranded.

Brake System Warning Light

This warning light may appear as:

• "BRAKE"

• An exclamation point inside a circle

• ABS indicator

Possible causes:

• Low brake fluid

• Worn brake pads

• ABS system issue

• Parking brake engaged

What to do:

If braking performance changes or the light stays illuminated, your Lexus should be inspected immediately.

Lexus Oil Pressure Warning Light

This warning light resembles an oil can.

What it means:

Your engine may not be receiving proper oil pressure, which can lead to engine damage if ignored.

What to do:

Safely pull over, turn off the engine, and check your oil level. Avoid continuing to drive until the issue is diagnosed.

Lexus Hybrid System Warning Light

Hybrid Lexus models like the RX Hybrid, NX Hybrid, and TX Hybrid may display a hybrid system warning.

Possible causes:

• Hybrid battery issue

• Electrical system malfunction

• Cooling system concern

What to do:

Schedule a professional inspection with a certified Lexus technician as soon as possible.

Traction Control Warning Light

This symbol usually shows a vehicle with skid marks behind it.

What it means:

The traction control system is actively helping maintain grip on slippery roads.

In Connecticut winters:

This light may briefly flash during snow, ice, or heavy rain conditions. If it remains on continuously, the system may require service.

Lexus Master Warning Light

Many newer Lexus models feature a master warning light shown as a triangle with an exclamation point.

What it means:

This is a general alert that may accompany another message in the vehicle information display.

What to do:

Check the information screen for additional details or schedule diagnostic service.
