2044-1. Before driving
GS450h_300h_OM_OM30F92E_(EE)
WARNING
Observe the following precautions. Failure to do so may result in death or serious injury.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and reduce your ability to control the vehicle.
●Sudden acceleration, engine braking due to shifting, or changes in engine speed
could cause the vehicle to skid, resulting in an accident.
●After driving through a puddle, lightly depress the brake pedal to make sure that the brakes are functioning properly. Wet brake pads may prevent the brakes from func-
tioning properly. If the brakes on only one side are wet and not functioning properly, steering control may be affected.
■When shifting the shift lever
●Do not let the vehicle roll backward while the shift lever is in a driving position, or rollforward while the shift lever is in R.Doing so may result in an accident or damage to the vehicle.
●Do not shift the shift lever to P while the vehicle is moving. Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to a driving position while the vehicle is moving backward. Doing so can damage the transmission and may result in a loss of vehicle control.
●Shifting the shift lever to N while the vehicle is moving will disengage the hybrid sys- tem. Engine braking is not available with the hybrid system disengaged.
●Be careful not to shift the shift lever with the accelerator pedal depressed. Shifting the
shift lever to any position other than P or N may lead to unexpected rapid accelera- tion of the vehicle that may cause an accident and result in death or serious injury.
■If you hear a squealing or scraping noise (brake pad wear indicators)
Have the brake pads checked and replaced by any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer as soon as possible. Rotor damage may result if the pads are not replaced when needed.
Front and rear* brakes: Moderate levels of brake pad and disc wear allow enhanced braking power. As a result, the discs may wear more quickly than conventional brakediscs. Therefore, when replacing the brake pads, Lexus recommends that you also
have the thickness of the discs measured. It is dangerous to drive the vehicle when th e wear limits of the brake pads and/or those of the brake discs are exceeded.

■Automatic headlight leveling system
The level of the headlights is automatically adjusted according to the number of passen- gers and the loading condition of the vehicle to ensure that the headlights do not inter-
fere with other road users.
■If the “AFS OFF” indicator flashes
It may indicate a malfunction in the system. Contact any authorized Lexus retailer or
Lexus authorized repairer, or any reliable repairer.

(Customizable features: P. 568)
The sensor may not function properly if an object is placed on the sensor, or anything that
blocks the sensor is affixed to the windshield. Doing so interferes with the sensor detectingthe level of ambient light and may cause the
automatic headlight system to malfunction.

■Conditions in which the light distribution control of the headlights changes automati-
cally
●When all of the following conditions are met, the high beams will be turned on automat- ically and the system will operate:
• The vehicle speed is approximately 60 km/h (37 mph) or more.*
*: The area in the direction that the vehicl e is turning will be illuminated more brightly
than other areas while driving on a curve.
●When all of the following conditions are met, the variable high beams will turn on and the distance that the low be ams are projected will be adjusted automatically, depending
on the location of vehicles ahead:
• The vehicle speed is approximately 60 km/h (37 mph) or more. • The area ahead of the vehicle is dark.
• There are vehicles ahead with headlights or tail lights turned on.
●If any of the following conditions is met, the high beams or variable high beams will be
changed to the low beams automatically:
• The vehicle speed is below approximately 60 km/h (37 mph). • The area ahead of the vehicle is not dark.
• There are many vehicles ahead. • Vehicles ahead are moving quickly and the high beams may blind the drivers of theother vehicles.
■Camera sensor detection information
●The high beams may not be automatically changed to the variable high beams in thefollowing situations:
• When vehicles ahead suddenly appear from a curve • When the vehicle is cut in front of by another vehicle• When vehicles ahead are hidden from sight due to repeated curves, road dividers or
roadside trees • When vehicles ahead appear from the faraway lane on wide road• When vehicles ahead have no lights
●The high beams may be changed to the variable high beams if a vehicle ahead that isusing fog lights without its headlights turned on is detected.
●House lights, street lights, traffic signals, and illuminated billboards or signs may cause the high beams to change to the variable high beams, cause the high beams not tochange to the variable high beams, or change the area that is not illuminated.
●The following factors may affect the amount of time taken to turn the high beam on or off, or the speed by which the areas not illuminated change:
• The brightness of headlights, fog light s, and tail lights of vehicles ahead
• The movement and direction of vehicles ahead • When a vehicle ahead only has operational lights on one side
• When a vehicle ahead is a two-wheeled vehicle • The condition of the road (gradient, curve, condition of the road surface etc.)• The number of passengers and amount of luggage
●The light distribution control of the headlights may change unexpectedly.
●Bicycles or similar objects may not be detected.
