The Lexus CT 200h electric / petrol hybrid car was initially released in 2011, with a modern style refresh occurring in 2013. Here we look at the Lexus CT 200h dashboard warning lights with each symbol meaning.
The dashboard instrument display may vary on your CT 200h depending on model version and year of manufacture. The dashboard warning lights below relate to all versions of the Lexus CT 200h.
The warning lights and indicators on the instrument cluster and center panel inform the driver of the status of the vehicle’s various systems. Some of the warning lights come on as the vehicle starts as part of the normal starting process.
|Symbol||Fault Description / Action|
|The Lexus CT 200h red brake system warning light and warning buzzer indicates that:
• The parking brake / handbrake is on
• The brake fluid level is low
• The brake system is malfunctioning
What to do
Check that the parking brake is fully released. If it is and the light remains on, check the brake fluid reservoir under the bonnet / hood and add fluid if necessary. If after this the light stays on, or brake fluid is at normal levels, do not continue to drive and contact a Lexus workshop.
|The Lexus CT 200h yellow brake system warning light indicates a malfunction in:
• The regenerative braking system
• The electronically controlled brake system
What to do
As this brake warning light is yellow, it isn't as urgent as the red symbol, but still requires you have the system serviced by a Lexus workshop as soon as possible.
|The Lexus CT 200h battery warning light is informing of a charging system fault.
What to do
It's advisable to stop as soon as possible, switch off the engine and contact a Lexus workshop. The engine will likely shut down after a period of time. To prolong the working of the vehicle, switch off any non-essential vehicle systems that use electric. Braking and cooling systems may be affected.
|The Lexus CT 200h oil light is an indication of low oil pressure. The engine lubrication system could be interrupted. This may result in severe engine damage.
What to do
Pull of the road, switch off the engine and do not continue your journey. Contact a Lexus workshop.
|The Lexus CT 200h malfunction indicator light (MIL) or 'check engine light' as it's also know as indicates a malfunction in:
• The hybrid system.
• The electronic engine control system.
• The electronic throttle control system.
• The emission control system (If equipped).
What to do
This warning is a generic fault light and as such requires diagnostic equipment to be connected to your Lexus. This equipment reads fault codes that enable engineers to diagnose the fault. Consult with a Lexus workshop.
|The Lexus CT 200h SRS (Supplemental Restraint System) / Airbag warning light indicates a malfunction in:
• The SRS airbag system and/or
• The seat belt pretensioner system.
What to do
During an impact, the airbags may not be deployed. This is usually a sensor fault. Have system check as soon as possible.
If fitting a front-facing child seat in the front passenger seat, you may wish to switch off the passenger airbag. Warning symbols indicated are:
Front passenger airbag ON.
Front passenger airbag OFF.
|The Lexus CT 200h ABS (anti-lock braking system) warning light indicates a malfunction in:
• The ABS and / or
• The brake assist system
ABS helps to prevent wheel locking under braking and brake assist applies the brakes if the system detects that the driver has not applied enough force to the brake pedal.
What to do
Normal brakes will continue to work as usual, though there is a risk of wheel locking when braking hard. ABS and brake assist use the same sensors. Have vehicle checked as soon as possible.
|The steering wheel with an exclamation mark / point is the Lexus CT 200h electric power steering system warning light and warning buzzer indicates a malfunction in the EPS (Electric Power Steering) system.
What to do
On occasions, with continuous full lock steering to the left and right (this could be when trying to park for example), the power steering module can overheat and will automatically be switched off or offer reduced assistance. This is temporary and will begin working once the system has cooled. If the warning light remains on, have it checked as soon as possible.
|The Lexus CT 200h PCS (Pre-Collision System) warning light indicates a malfunction in the PCS or that the system is temporarily unavailable due to the vehicle being extremely hot/cold, or dirt around a front sensor, etc.|
|The Lexus CT 200h LDA (Lane Departure Alert) warning light comes on in yellow indicating a fault in the system. When the message 'Lane Departure Alert Unavailable' is displayed on the information display, turn off the LDA system, continue to drive the vehicle for a short time, and turn the LDA system back on.|
|The Lexus CT 200h VSC light stand for 'Vehicle Stability Control'. This system helps to keep the vehicle stable when traveling around corners and uses traction control (TRC) to help prevent wheel slip when accelerating and assists with hill starts to prevent rolling. If the VSC light comes on and stays on, there is a fault with the system. It's often related to ABS sensors as they share the same components. If the VSC light flashes, this means the system is active and attempting to keep the vehicle stable. Traction control may need to be switched off, such as when stuck in snow for example. The TRC OFF warning light will display when the system is manually turned off.|
|This warning light indicates a fault with the automatic headlight leveling system. This is often a sensor fault which fails to detect when the car is tilted forward or backwards.|
|The Lexus CT 200h engine overheating warning light comes on or flashes informs the driver that the engine coolant is too high.
• Stop the vehicle and if applicable, turn off the air conditioning system, and then stop the hybrid system.
• If there is steam, slowly lift the hood / bonnet to help cool the engine and wait for the steam to subside.
• Check for any leaks in the radiator or hose. If there is coolant leaking, do not continue to drive and contact a Lexus workshop.
• When the engine has cooled, check coolant levels in the reservoir tank and add fluid if required.
• Now start the hybrid system and turn on the air conditioning system on. Check radiator fans are working (the fans come on automatically from a cold start when the air conditioning system is on).You should be able to hear the fans - if not turn the air-con on and off to listen. If the radiator fans are not working, do not continue to drive and contact Lexus.

• Fault - the tyre pressure warning light will flash for 1 minute (then stay on). This indicates a fault with the tyre pressure monitoring system.
|This symbol indicates that the The Lexus CT 200h Automatic High Beam system is active. The high beam may not be automatically turned off and will require manual operation in the following situations:
• Oncoming vehicles suddenly appear from a sharp bend in the road.

Six sensors; 2 on the front corners, 2 on the rear corners and 2 located centre-rear alert the driver via a display and buzzer. The buzzer sounds faster as the vehicle approaches an obstacle. For the buzzer to sound continuously, the following distances apply to the parking sensors:
• Front corner sensors 30 cm (1.0 ft.)
• Rear corner sensors 30 cm (1.0 ft.)
• Rear center sensors 35 cm (1.2 ft.)
Start of object detection and when the buzzer begins to warn the driver is approximately:
• Front corner sensors 50 cm (1.6 ft.)
• Rear corner sensors 60 cm (2.0 ft.)
• Rear center sensors 150 cm (4.9 ft.)
