■Tire types
●Summer tires
Summer tires are high-speed performance tires best suited to highway driving under
dry conditions. Since summer tires do not have the same traction performance as
snow tires, summer tires are inadequate for driving on snow-covered or icy roads. For
driving on snow-covered roads or icy roads, the use of snow tires is recommended.
When installing snow tires, be sure to replace all four tires.
●All season tires
All season tires are designed to provide better traction in snow and to be adequate for
driving in most winter conditions as well as for use year-round. All season tires, how-
ever, do not have adequate traction performance compared with snow tires in heavy
or loose snow. Also, all season tires fall
short in acceleration and handling perfor-
mance compared with summer tires in highway driving.
●Snow tires
For driving on snow-covered roads or icy roads, we recommend using snow tires. If
you need snow tires, select tires of the same size, construction and load capacity as the
originally installed tires. Since your vehicle has radial tires as original equipment, make
sure your snow tires also have radial cons truction. Do not install studded tires without
first checking local regulations for possible restrictions. Snow tires should be installed
on all wheels. ( →P. 2 6 3 )
■If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is lost.
■Situations in which the tire pressure warning system may not operate properly
●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.
• Tire chains etc. are equipped.
• An auxiliary-supported run-flat tire is equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the wheels or wheel
housings.
• If the tire inflation pressure is extremely higher than the specified level.
●Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large display, air-
port or other facility that generates st rong radio waves or electrical noise
• When carrying a portable radio, cellular phone, cordless phone or other wireless communication device
If tire position information is not correctl y displayed due to the radio wave conditions,
the display may be corrected by driving and changing the radio wave conditions.
●When the vehicle is parked, the time taken for the warning to start or go off could be
extended.
●When tire inflation pressure declines rapidly for example when a tire has burst, the
warning may not function.

■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as dangerous han-
dling characteristics, which may lead to an a
ccident resulting in death or serious injury.
●Make sure to install four tires that are of the specified size, and that all four tires are of
the same size, same brand, and same tread pattern.
●Do not use tire sizes other than those recommended by Lexus.
●Do not mix differently constructed tires (radial, bias-belted or bias-ply tires).
●If only two tires are replaced, the new tires should be placed on the rear of the vehicle.
●Do not mix summer, all season and snow tires.
●Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
●Do not tow if your vehicle has a compact spare tire installed.
■When initializing the tire pressure warning system
Do not operate the tire pressure warning reset switch without first adjusting the tire
inflation pressure to the specified level. Otherwise, the tire pressure warning light may
not come on even if the tire inflation pressu re is low, or it may come on when the tire
inflation pressure is actually normal.
■Caution regarding interference with electronic devices
●Users of any electrical medical device other than implantable cardiac pacemakers,
cardiac resynchronization therapy-pacemakers or implantable cardioverter defibril-
lators should consult the manufacturer of the device for information about its opera-
tion under the influence of radio waves.
Radio waves could have unexpected effects on the operation of such medical
devices.
●People with implantable cardiac pacemakers,
cardiac resynchronization therapy-pacemak-
ers or implantable cardioverter defibrillators
should not come within 17.7 in. (450 mm) of
the tire pressure warning system initiators.
The radio waves may affect the operation of
such devices.

AVERTISSEMENT
■Précautions relatives aux coussins gonflables SRS
●N’utilisez pas d’accessoires recouvrant les parties du siège où les coussins gonflables
SRS latéraux se déploient, car ces accessoires pourraient entraver le déploiement
des coussins gonflables. De tels accessoires peuvent empêcher les coussins gonfla-
bles latéraux de se déployer correctement, rendre le système inopérant ou provo-
quer accidentellement le déploiement des coussins gonflables latéraux,
occasionnant des blessures graves, voire mortelles.
●Ne frappez pas et n’appliquez pas une pression importante à l’emplacement des
composants des coussins gonflables SRS.
Cela peut provoquer un mauvais fonctionnement des coussins gonflables SRS.
●Ne touchez à aucun composant des coussi ns gonflables SRS immédiatement après
leur déploiement (gonflage), car ils pourraient être chauds.
●Si vous avez de la difficulté à respirer après le déploiement des coussins gonflables
SRS, ouvrez une portière ou une glace pour laisser entrer l’air, ou quittez le véhicule
si vous pouvez le faire en toute sécurité. Dès que possible, nettoyez tous les résidus
afin d’éviter les irritations cutanées.
●Si les emplacements de stockage des coussins gonflables SRS, tels que le tampon de
volant et les garnitures des montants avan t et arrière, sont endommagés ou fissurés,
faites-les remplacer par votre concessionnaire Lexus.
■Modification et mise au rebut des composants du système de coussins gonflables
SRS
Ne mettez pas votre véhicule au rebut et n’effectuez aucune des modifications suivan-
tes sans d’abord consulter votre concessionnaire Lexus. Les coussins gonflables SRS
pourraient fonctionner de manière incorrecte ou se déployer (gonfler) accidentelle-
ment, ce qui serait susceptible d’occasionner des blessures graves, voire mortelles.
●Installation, retrait, démontage et réparation des coussins gonflables SRS
●Réparations, modifications, retrait ou remplacement du volant, du tableau de bord,
de la planche de bord, de la boîte à gants, des sièges ou du capitonnage des sièges,
des montants avant, latéraux et arrière, ou des brancards de pavillon
●Réparations ou modifications de l’aile avant, du pare-chocs avant ou du côté de
l’habitacle
●Installation d’une protection de calandre (barre safari, barre kangourou, etc.), de
lames de déneigement ou de treuils
●Modifications du système de suspension du véhicule
●Installation d’appareils électroniques tels qu’un émetteur-récepteur radio ou un lec-
teur de CD
●Modifications à votre véhicule pour une personne aux capacités physiques réduites
