tire’s angle as controlled by steering input.
AFS operates at speeds of 10 km/h (6 mph) or higher.
■Daytime running light system
To make your vehicle more visible to othe r drivers during daytime driving, the day-
time running lights turn on automatically whenever the hybrid system is started and
the parking brake is released with the headlight switch off or in the position. (Illu-
minate brighter than the front position lights.)
Daytime running lights are not designed for use at night.

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 immediately 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 wind-
shield.
●Check for and remove any excess ice or snow that may have accumu-
lated 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.
Accelerate the vehicle slowly, keep a safe distance between you and the
vehicle ahead, and drive at a reduced speed suitable to road conditions.
●Park the vehicle and move the shift lever to P without setting the park-
ing brake. The parking brake may free ze up, preventing it from being
released. If the vehicle is parked without setting the parking brake,
make sure to block the wheels.
Failure to do so may be dangerous because it may cause the vehicle to
move unexpectedly, possibly leading to an accident.
●If the vehicle is parked without setting the parking brake, confirm that
the shift lever cannot be moved out of P*.
*: The shift lever will be locked if it is attempted to be shifted from P to any other
position without depressing the brake pedal. If the shift lever can be shifted
from P, there may be a problem with the shift lock system. Have the vehicle
inspected by any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional.
