Lexus Safey System+ Settings

April 4th, 2016 by

The new Lexus Safety System+ package is available now and is being added to additional models and package levels with the ultimate goal of making this comprehensive safety package standard on all Lexus.  Currently there are several models that include the Safety System+ Package such as the Lexus ES, new RX and Lexus LX with more models anticipated for later this year.  You can learn more about the new Safety System+ package here.

Safety System+ includes Pre-Collision with Pedestrian Detection, Lane Departure Alert with Steering Assist, Lane Keep Assist (on specific models), Dynamic Radar Cruise Control and Intelligent High Beams.  Just like most of most Lexus technology features, you can elect to change,turn on or off most of the features included in this dynamic safety package and if you continue reading below, you can learn how the Lexus Safety System+ settings work…

Safety System+ Steering Wheel Controls

Steering wheel controls for Lane Departure Alert, Dynamic Radar Cruise Control, Pre-Collision System and more.

Pre-Collision System with Pedestrian Detection Setting Options

The Lexus Pre-Collision System (PCS) with Pedestrian Detection is designed to help the driver avoid certain potentially severe frontal collisions or decrease the severity of a frontal impact.  The Lexus PCS uses a grill-mounted radar technology along with a monocular camera mounted above the rearview mirror to help detect vehicles and pedestrians under certain conditions.  If the PCS detects objects, the system activates an audible and visual alert (BRAKE! BRAKE!) plus brake assist if the driver applies the brakes, followed by automatic braking if the driver does not brake in time to avoid a collision themselves.  The Lexus Pre-Collision System that is on new Lexus models will automatically be turned on and engaged but you can adjust some of the settings.

One setting available for adjustment with PCS is the Alert Timing.  Alert timing can be changed from the default setting of “Middle” to “Far” or “Near”, and will remain at this setting even after the engine is turned off.  Below is a table showing the different distance settings including the default and customized setting options.


There is a way and specific instance when you may turn-off or disengage the PCS, however we recommend calling your service advisor for assistance or any questions that you may have before turning the system off.  Some of the instances where you may need to turn off PCS include:

  • When the vehicle is being towed or when towing another vehicle.
  • If the tires are not properly inflated or are very worn.
  • When a compact spare tire or an emergency tire puncture repair kit is used.
  • If the suspension is modified.
  • If the front of the vehicle is raised or lowered, such as when loaded with heavy luggage.

To customize or disengage PCS you will need to access the steering-wheel mounted switch on the multi-information display screen that looks like a cog (gear) and select Pre-Collision System (“PCS”).  From here, you can change the alert timing or turn-off the system.  When the system is turned-off, the PCS warning light will illuminate and a message will display on the MID.  The system will automatically re-engage or turn back on each time the engine is turned on.

Lane Departure Alert with Steering Assist Setting Options


Lane Departure Alert is pretty self-explanatory, but in case you didn’t know, the LDA system is designed to alert the driver if it detects an unintentional lane departure (if a turn signal is on in the direction of the departure then this would not activate) on roads with clear visible markings.

To engage the system, press the LDA switch on the steering wheel (as shown above).  The LDA indicator light will illuminate and a message with be displayed.  Press the LDA button again to turn the system off.  The LDA feature will remain on or off the next time you turn off-and on the engine.

LDA Customization Features:

  • Turn Steering Assist on or off
  • Change the alert from steering wheel vibration to a buzzer sound
  • Modify alert sensitivity
  • Turn the vehicle sway warning on or off
  • Modify vehicle sway sensitivity

To access the settings you will select the same cog (gear icon) on your multi-information display screen and select “LDA”.


If your Lexus includes the Lane Keep Assist feature- which uses Dynamic Radar Cruise Control and Lane Centering to monitor the position of the vehicle relative to its lane and applies small amounts of steering input, as needed, using the Electronic Power Steering system to help keep the vehicle centered within its lane- then you can also customize a few settings.  LKA is accessed the same way as the settings described above.


Dynamic Radar Cruise Control Settings

Dynamic Radar Cruise Control is used on highways and is designed to detect a vehicle traveling directly ahead and determine its speed.  The system then automatically adjusts your vehicles speed (within a set range) to help maintain your desired distance.


Activate the DRCC by pressing the cruise control “On/Off” button.  The radar cruise control indicator will come on and “RADAR READY” will display on your Multi-Information Display screen.  To adjust the DRCC must be engaged before changing the follow distance setting of “Long” (Long being the default setting) to “Medium” or “Short”.


Using the steering wheel mounted controls, you can change the following distance settings.

Medium gives you a distance of approximately 130 feet.

Short makes the distance around 100 feet.

The default “Long” setting will return the next time you turn-off and back on the engine.


There are instances when you should turn-off the DRCC feature.  These instances include:

  • Roads where there are pedestrians, cyclists or heavy snow
  • On winding roads
  • When driving on rain, ice or slippery roads
  • At entrances to freeways or highways
  • When towing
  • In traffic that requires immediate and frequent acceleration or deceleration.


Intelligent High-Beam Settings


With vehicles equipped with Intelligent High-Beams, our sales and delivery specialists at Lexus Dominion will engage the system at time of delivery- but you can engage or disengage this feature yourself at any time by pushing the lever away from you with the headlamp switch in the AUTO position.  You can also press the AUTO switch to engage the system if the headlight lever is already pushed forward.  The green AUTO light on your MID will illuminate when turned on as pictured above.

The setting available for adjustment is the sensor sensitivity.  To temporary adjust the sensor sensitivity make sure the system is on then the engine OFF and then switch to IGNITION ON mode.  You then have 30 seconds to do the following:

  1. Pull headlamp lever to original position and then push it back to high-beam position quickly 10 times.
  2. Leave the lever in high-beam position
  3. The Intelligent High-Beam indicator will flash three times to indicate the sensitivity is lowered.
