Page 34 1-1. For safe use Seat belt pretensioners (front and outboard rear seats) The pretensioner helps the seat belt to quickly restrain the occupant by retracting the seat belt when the vehicle is subjected to certain types of severe frontal collision. The front seat pretensioners also acti- vate when the vehicle is subjected to certain types of severe side collision.
Page 35 Each seat belt should be used by one person only. Do not use a seat belt for more ● than one person at once, including children. Lexus recommends that children be seated in the rear seat and always use a seat ● belt and/or an appropriate child restraint system.
Page 36 Seat belt pretensioners ■ If the pretensioner has activated, the SRS warning light will come on. In that case, the seat belt cannot be used again and must be replaced at your Lexus dealer. Adjustable shoulder anchor ■ Always make sure the shoulder belt is positioned across the center of your shoul- der.
Page 37 Ensure that the belt and plate are locked and the belt is not twisted. ● If the seat belt does not function correctly, immediately contact your Lexus dealer. Replace the seat assembly, including the belts, if your vehicle has been involved in ●...
Page 38: Srs Airbags
1-1. For safe use SRS airbags The SRS airbags inflate when the vehicle is subjected to certain types of severe impacts that may cause significant injury to the occupants. They work together with the seat belts to help reduce the risk of death or serious injury.

Page 46 1-1. For safe use SRS airbag deployment conditions (SRS front airbags) ■ The SRS front airbags will deploy in the event of an impact that exceeds the set ● threshold level (the level of force corresponding to an approximately 12 - 18 mph [20 - 30 km/h] frontal collision with a fixed wall that does not move or deform).
Page 47 1-1. For safe use Types of collisions that may not deploy the SRS airbags (SRS front airbags) ■ The SRS front airbags do not generally inflate if the vehicle is involved in a side or rear collision, if it rolls over, or if it is involved in a low-speed frontal collision. But, whenever a collision of any type causes sufficient forward deceleration of the vehi- cle, deployment of the SRS front airbags may occur.
Page 48 1-1. For safe use When to contact your Lexus dealer ■ In the following cases, the vehicle will require inspection and/or repair. Contact your Lexus dealer as soon as possible. Any of the SRS airbags have been inflated. ● The front of the vehicle is damaged or ●...

Page 57: Child Restraint Systems
1-1. For safe use Child restraint systems A child restraint system for a small child or baby must itself be properly restrained on the seat with the LATCH anchors or the lap portion of the lap/shoulder belt. The laws of all 50 states of the U.S.A. and Canada now require the use of child restraint systems.
Page 58 1-1. For safe use Types of child restraints Child restraint systems are classified into the following 3 types according to the age and size of the child: Rear facing  Infant seat/con- Forward facing  Convertible   vertible seat seat Booster seat ...
Page 59 In an accident, the child can be crushed against the wind- shield, or between you and the vehicle’ s interior. Lexus strongly urges the use of a proper child restraint system that conforms to ● the size of the child, installed on the rear seat. According to accident statistics, the child is safer when properly restrained in the rear seat than in the front seat.
Page 60 1-1. For safe use CAUTION 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 other serious injuries that could result in death.
Page 61: Installing Child Restraints
1-1. For safe use Installing child restraints Follow the child restraint system manufacturer’s instructions. Firmly secure child restraints to the seats using the LATCH anchors or a seat belt. Attach the top tether strap when installing a child restraint. The lap/shoulder belt can be used if your child restraint system is not compatible with the LATCH (Lower Anchors and Tethers for Children) system.
Page 62 1-1. For safe use Installation with LATCH system Remove the head restraint. Widen the gap between the seat cushion and seatback slightly. Type A  Latch the hooks of the lower straps onto the LATCH anchors. If the child restraint has a top tether strap, the top tether strap should be latched onto the top tether strap anchor.
Page 63 1-1. For safe use Type B  Latch the buckles onto the LATCH anchors. If the child restraint has a top tether strap, the top tether strap should be latched onto the top tether strap anchor. For owners in Canada: The symbol on a child restraint system indicates the presence of a lower connector system.
Page 64 1-1. For safe use Installing child restraints using a seat belt (child restraint lock function belt) Rear-facing  Infant seat/convertible seat ■ Place the child restraint system on the rear seat facing the rear of the vehicle. Run the seat belt through the child restraint system and insert the plate into the buckle.
Page 65 1-1. For safe use While pushing child restraint system down into the rear seat, allow the shoulder belt to retract until the child restraint system is securely in place. After the shoulder belt has retracted to a point where there is no slack in the belt, pull the belt to check that it cannot be extended.
Page 66 1-1. For safe use Run the seat belt through the child restraint system and insert the plate into the buckle. Make sure that the belt is not twisted. Fully extend the shoulder belt and allow it to retract to put it in lock mode.

Page 68 1-1. For safe use Child restraint systems with a top tether strap Rear outboard seats: Remove the head restraint. Secure the child restraint system using the seat belt or LATCH anchors. Open the anchor bracket cover, latch the hook onto the anchor bracket and tighten the top tether strap.
Page 69 1-1. For safe use CAUTION When installing a booster seat ■ To prevent the belt from going into ALR lock mode, do not fully extend the shoul- der belt. ALR mode causes the belt to tighten only. This could cause injury or dis- comfort to the child.

1-2. Hybrid system Hybrid system features Your vehicle is a hybrid vehicle. It has characteristics different from conventional vehicles. Be sure you are closely familiar with the charac- teristics of your vehicle, and operate with care. The hybrid system combines the use of a gasoline engine and an elec- tric motor (traction motor) according to driving conditions, improving fuel efficiency and reducing exhaust emissions.
Page 73 1-2. Hybrid system ◆ When stopped/during start off The gasoline engine stops when the vehicle is stopped. During start off, the electric motor (traction motor) drives the vehicle. At slow speeds or when traveling down a gentle slope, the engine is stopped and the elec- tric motor (traction motor) is used.

Replacing tires and wheels ■ If the ID code of the tire pressure warning valve and transmitter is not registered, the tire pressure warning system will not work properly.
Page 448 6-3. Do-it-yourself maintenance Low profile tires (except 225/50R17 tires) ■ Generally, low profile tires will wear more rapidly and tire grip performance will be reduced on snowy and/or icy roads when compared to standard tires. Be sure to use snow tires or tire chains on snowy and/or icy roads and drive carefully at a speed appropriate for road and weather conditions.
Page 449 In the following cases, the tire pressure warning system may not operate properly. ● • If non-genuine Lexus wheels are used. • A tire has been replaced with a tire that is not an OE (Original Equipment) tire. • A tire has been replaced with a tire that is not of the specified size.

Page 451 Do not mix tires of different makes, models or tread patterns. ● Also, do not mix tires of remarkably different treadwear. Do not use tire sizes other than those recommended by Lexus. ● Do not mix differently constructed tires (radial, bias-belted or bias-ply tires).
Page 452 When a tire is repaired with liquid sealants, the tire pressure warning valve and transmitter may not operate properly. If a liquid sealant is used, contact your Lexus dealer or other qualified service shop as soon as possible. Make sure to replace the tire pressure warning valve and transmitter when replacing the tire.
