IS300h_EE(OM53D89E)
WARNING
■People suffering illness
Obtain medical advice and wear the seat belt in the proper way. (P. 38)
■When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes twisted around a child’s neck, it may lead to choking or othe r serious injuries that could result in death.
If this occurs and the buckle cannot be unfa stened, scissors should be used to cut the
belt.
■Seat belt pretensioners
If the pretensioner has activated, the SRS wa rning light will come on. In that case, the
seat belt cannot be used again and must be replaced at any authorized Lexus retailer or Lexus authorized repairer , or any reliable repairer.
■Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the center of your shoulder. The belt should be kept away from your neck , but not falling off your shoulder. Failure to
do so could reduce the amount of protection in an accident and cause death or serious
injuries in the event of a sudden stop, sudden swerve or accident. (P. 39)
■Seat belt damage and wear
●Do not damage the seat belts by allowing the belt, plate, or buckle to be jammed in
the door.
●Inspect the seat belt system periodically. Check for cuts, fraying, and loose parts. Do
not use a damaged seat belt until it is replaced. Damaged seat belts cannot protect an
occupant from death or serious injury.
●Ensure that the belt and plate are locked and the belt is not twisted.
If the seat belt does not function correctl y, immediately contact any authorized Lexus
retailer or Lexus authorized repa irer, or any reliable repairer.
●Replace the seat assembly, including the belts, if your vehicle has been involved in a
serious accident, even if there is no obvious damage.
●Do not attempt to install, remove, modify, disassemble or dispose of the seat belts. Have any necessary repairs carried out by any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repa irer. Inappropriate handling may lead to
incorrect operation.

tact with the shift lever, wiper switch etc.

dentally.

parts, such as the power window, hood, trunk, seats etc.
Safety information for children
Observe the following precautions when children are in the vehicle.
