LS500_OM_(U)_1810 low speed for an extended period, such
as in heavy traffic.■
When the battery is removed or dis-
charged●
Information stored in the ECU is cleared.
When the battery is depleted, have the
vehicle inspected at your Lexus dealer.●
Some systems may require initialization.
(  P.481)■
When removing the battery terminals
When the battery terminals are removed,
the information stored in the ECU is
cleared. Before removi ng the battery termi-
nals, contact your Lexus dealer. ■
Charging the battery
The electricity stored in the battery will dis-
charge gradually even when the vehicle is
not in use, due to natural discharge and the
draining effects of certain electrical appli-
ances. If the vehicle is left for a long time,
the battery may discharge, and the engine
may be unable to start. (The battery
recharges automatically during driving.) ■
When recharging or replacing the bat-
tery●
In some cases, it may not be possible to
unlock the doors using the smart access
system with push-button start when the
battery is discharged. Use the wireless
remote control or the mechanical key to
lock or unlock the doors.●
The engine may not start on the first
attempt after the battery has recharged
but will start normally after the second
attempt. This is not a malfunction.●
The engine switch mode is memorized by
the vehicle. When the battery is recon-
nected, the system will return to the
mode it was in before the battery was dis-
charged. Before di sconnecting the bat-
tery, turn the engine switch off.
If you are unsure what mode the engine
switch was in befo re the battery dis-
charged, be especially careful when
reconnecting the battery.
■
When replacing the battery
●
Use a Central Degassing type battery
(European Regulations). ●
Use a battery with the same case size as
the previous battery and an equivalent
20 hour rate capacity (20HR) or greater.
• If the sizes differ, the battery cannot be
properly secured.
• If the 20 hour rate capacity is low, even if
the time period where the vehicle is not
used is a short time, the battery may dis-
charge and the engine may not be able to
start. ●
Use a battery with a handle. If a battery
without a handle is used, removal is more
difficult. ●
After replacing, firm ly attach the follow-
ing items to the exhaust hole of the bat-
tery.
• Use the exhaust hose that was attached
to the battery before replacing and con-
firm that it is firmly connected to the hole
section of the vehicle.
• Use the exhaust hole plug included with
the battery replaced or the one installed
on the battery prior to the replacement.
(Depending on the battery to be
replaced, the exhaust hole may be
plugged.)

When inspecting under the hood of
your vehicle
Observe the following precautions.
Failure to do so may result in serious
injury such as burns. ●
If steam is seen coming from under the
hood, do not open the hood until the
steam has subsided. The engine com-
partment may be very hot. ●
Keep hands and clothing (especially a
tie, a scarf or a muffler) away from the
fan and belts.
Failure to do so may cause the hands
or clothing to be caught, resulting in
serious injury. ●
Do not loosen the coolant inlet cap,
the engine coolant reservoir cap or the
intercooler coolant reservoir cap while
the engine and radiator are hot.
High temperature steam or coolant
could spray out.
NOTICE
■
When adding engine coolant
Add coolant slowly after the engine has
cooled down sufficiently. Adding cool
coolant to a hot engine too quickly can
cause damage to the engine.
■
To prevent damage to the cooling sys-
tem
Observe the following precautions:
●
Avoid contaminating the coolant with
foreign matter (such as sand or dust
etc.).

460 8-1. Specifications
LS500_OM_(U)_1810 ■
Traction AA, A, B, C
The traction grades, from highest to
lowest, are AA, A, B and C, and they
represent the tire’s ability to stop on
wet pavement as measured under con-
trolled conditions on specified govern-
ment test surfaces of asphalt and
concrete. A tire marked C may have poor traction
performance.
Warning: The traction grade assigned to
this tire is based on braking (straight
ahead) traction tests and does not include
cornering (turning) traction. ■
Temperature A, B, C
The temperature grades are A (the
highest), B, and C, representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under controlled condi-
tions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire to degenerate and
reduce tire life, and excessive temperature
can lead to sudd en tire failure.
Grade C corresponds to a level of perfor-
mance which all passenger car tires must
meet under the Fede ral Motor Vehicle
Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.
Warning: The temperature grades of a tire
assume that it is prop erly inflated and not
overloaded.
Excessive speed, unde rinflation, or exces-
sive loading, either separately or in combi-
nation, can cause heat buildup and
possible tire failure.

ATTENTION■
Précautions relatives aux coussins
gonflables SRS
Respectez les précautions suivantes
concernant les coussins gonflables SRS.
Le non-respect de ces précautions peut
occasionner des blessures graves, voire
mortelles.
●
Le conducteur et tous les passagers du
véhicule doivent porter correctement
leur ceinture de sécurité.
Les coussins gonflables SRS sont des
dispositifs supplémentaires à utiliser
avec les ceinture s de sécurité. ●
Le coussin gonflable conducteur SRS
se déploie avec une force con-
sidérable, pouvant occasionner des
blessures graves, voire mortelles, si le
conducteur se trouve très près du
coussin gonflable.
L'autorité fédérale ch argée de la sécurité
routière aux États-Unis (NHTSA) con-
seille: La zone à risque du coussin gon-
flable conducteur se situant dans les
premiers 2 à 3 in. (50 à 75 mm) de
déploiement, vous placer à 10 in. (250
mm) de votre coussin gonflable conduc-
teur vous garantit une marge de sécurité
suffisante. Cette distance est à mesurer
entre le centre du vola nt et le sternum. Si
vous êtes assis à moins de 10 in. (250
mm), vous pouvez changer votre posi-
tion de conduite de plusieurs façons:
• Reculez votre siège le plus possible, de
manière à pouvoir encore atteindre
confortablement les pédales.

4919-1. For owners
LS500_OM_(U)_1810 9
For owners ATTENTION●
Ne fixez rien et ne posez rien sur des
emplacements tels que la planche de
bord, la garniture du volant et la partie
inférieure du tableau de bord.
Ces éléments peuvent se transformer
en projectiles lorsque les coussins
gonflables conducteur, passager avant
et genoux SRS se déploient.
●
Ne fixez rien aux portes, à la vitre du
pare-brise, aux vitres latérales, aux
montants avant et arrière, au rail latéral
de toit et à la po ignée de maintien.
●
Ne suspendez aucun cintre ou objet
dur aux crochets à vêtements. Tous
ces objets pourraient se transformer
en projectiles et causer des blessures
graves, voire mortelles en cas de
déploiement des coussins gonflables
rideaux SRS.
●
Si un cache en vinyle est placé sur la
zone où le coussin gonflable de
genoux SRS se déploie, assurez-vous
de le retirer. ●
N'utilisez aucun accessoire de siège
recouvrant les zones de déploiement
des coussins gonflables latéraux SRS,
car il risque de gêner le déploiement
des coussins gonflables SRS. De tels
accessoires peuvent empêcher les
coussins gonflables latéraux de
fonctionner correcte ment, désactiver
le système ou entraîner le déploiement
accidentel des coussins gonflables
latéraux, occasionna nt des blessures
graves, voire mortelles. ●
Évitez de faire subir des chocs ou des
pressions excessives aux parties ren-
fermant les composants de coussins
gonflables SRS ou aux portes avant.
En effet, cela pourra it entraîner un dys-
fonctionnement des coussins gonfla-
bles SRS. ●
Ne touchez aucun composant
immédiatement après le déploiement
(gonflage) des coussins gonflables
SRS, car ils peuvent être chauds. ●
Si vous avez des di fficultés à respirer
après le déploiement des coussins
gonflables SRS, ouvrez une porte ou
une vitre pour faire entrer de l'air frais,
ou bien descendez du véhicule si cela
ne présente pas de danger. Essuyez
tout résidu dès que possible afin
d'éviter d'éventuelle s irritations de la
peau.
●
Si les partie s renfermant les coussins
gonflables SRS, comme les garnitures
du volant et des montants avant et
arrière, sont endommagées ou cra-
quelées, faites-les remplacer par votre
concessionnaire Lexus.
●
Ne placez rien sur le siège du pas-
sager avant, comme un coussin par
exemple. Cela a pour conséquence de
répartir le poids du passager sur toute
la surface du siège, ce qui empêche le
capteur de détecter correctement le
poids du passager. En conséquence,
les coussins gonflables frontaux SRS
du passager avant risquent de ne pas
se déployer en cas de collision.
