■Dynamic radar cruise control can be set when
●The shift lever is in D or range 4 or higher of S has been selected.
●Vehicle speed is above approximately 30 mph (50 km/h).
■Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After accelerating, the
set speed resumes. However, during vehicle-to-vehicle distance control mode, the vehi-
cle speed may decrease below the set speed in order to maintain the distance to the pre-
ceding vehicle.
■Automatic cancelation of vehicle- to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the following situ-
ations:
●VSC is activated.
●TRAC is activated for a period of time.
●When the VSC or TRAC system is turned off by pressing the VSC OFF switch.
●The sensor cannot detect properly beca use it is obstructed in some way.
●Pre-collision braking is activated.
When vehicle-to-vehicle distance control mo de is automatically canceled in the follow-
ing situations, “Radar Cruise Control Unavaila ble” will be displayed on the multi-infor-
mation display:
●Actual vehicle speed falls below approximately 25 mph (40 km/h).
●The windshield wipers are oper ating at high speed (when the wiper switch is set to the
“AUTO” mode or the high speed wiper operation position).
If vehicle-to-vehicle distance control mode is automatically canceled for any other rea-
son, there may be a malfunction in the system. Contact your Lexus dealer.
■Automatic cancelation of constant speed control mode
Constant speed control mode is automatica lly canceled in the following situations:
●Actual vehicle speed is more than approximately 10 mph (16 km/h) below the set vehi-
cle speed.
●Actual vehicle speed falls below approximately 25 mph (40 km/h).
●VSC is activated.
●TRAC is activated for a period of time.

LDA (Lane Departure Alert with steering control)
While driving on a highway or freeway that has white (or yellow) lane markers
and few curves, a camera, which is located on the upper part of the windshield,
uses this system to recognize the white (yellow) lane markers and when the
driver has deviated from the lane. If the system judges that the vehicle has devi-
ated from the current traffic lane, along with alerting the driver with a buzzer and
indications in the multi-information display, it will provide assistance by operating
the steering wheel to avoid further deviation from the marker lines.

NOTICE
■To prevent damage to or incorrect operation of the LDA
Observe the following to ensure that the LDA system functions correctly
●Do not modify the headlights or attach stickers to the surface of the lights.
●Do not modify the suspension or replace it with non-genuine parts.
●Do not install or place anything on the hood or the grille. Also, do not install a grille
guard (bull bars, kangaroo bar, etc.).
●If your windshield needs repairs, contact your Lexus dealer.
●Do not overload with luggage
■ Lane recognition camera
Observe the following to ensure that the LDA system functions correctly
●Keep the windshield clean at all times.
Performance could be affected if the windshie ld is dirty, or if raindrops, condensation
or ice are adhering to the windshield.
●Do not spill liquids onto the lane recognition camera.
●Do not attach window tinting to the windshield.
●Do not install an antenna in fron t of the lane recognition camera.
●If the windshield area in front of the lane recognition camera is fogged up, use the
windshield defogger to remove the fog from that area. ( P. 4 3 5 )
When it is cold, using the he ater with air blowing to the feet may allow the upper part
of the windshield to fog up. This will have a negative effect on the images.
●Do not scratch the camera lens, or let it get dirty.
When cleaning the inside of the windshield , be careful not to get any glass cleaner,
etc., on the lens. Also, do not touch the lens.
For lens repair, contact your Lexus dealer.
●Do not change the installation position or direction of the lane recognition camera or
remove it.
The direction of the lane recognit ion camera is precisely adjusted.
●Do not subject the lane recognition camera to strong impact or force, and do not dis-
assemble the lane recognition camera.
●Do not replace windshield with non-genuine windshield.
Contact your Lexus dealer.
●Do not attach a sticker or other items to the
windshield near the lane recognition camera.

Winter driving tips
●Use fluids that are appropriate to the prevailing outside temperatures. •Engine oil
• Engine/power control unit coolant
• Washer fluid
●Have a service technician inspect the condition of the 12-volt battery.
●Have the vehicle fitted with four snow tires or purchase a set of tire chains for
the front tires
*.
Ensure that all tires are the same size and br and, and that chains match the size of the
tires.
*: Tire chains cannot be mounted on the 225/60R18 tires.
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is frozen. Pour
warm water over the frozen area to melt the ice. Wipe away the water imme-
diately to prevent it from freezing.
●To ensure proper operation of the climate control system fan, remove any
snow that has accumulated on the air inlet vents in front of the windshield.
●Check for and remove any excess ice or snow that may have accumulated on
the exterior lights, vehicle’s roof, chassis, around the tires or on the brakes.
●Remove any snow or mud from the bottom of your shoes before getting in the
vehicle.
Carry out the necessary preparations and inspections before driving the vehi-
cle in winter. Always drive the vehicle in a manner appropriate to the prevail-
ing weather conditions.
