3227-2. Steps to take in an emergency
WARNING
Please note that the TPMS (tire pressure warning system) is not a substitute for proper
tire maintenance, and it is th e driver’s responsibility to ma intain correct tire pressure,
even if under-inflation has not reached the le vel to trigger illumination of the TPMS low
tire pressure telltale (tire pressu re warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning system) mal-
function indicator to indicate when the system is not operating properly. The TPMS (tire
pressure warning system) malfunction indicator is combined with the low tire pressure
telltale (tire pressure warning light). When the system detect s a malfunction, the telltale
will flash for approximately one minute and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle start-ups as long as the malfunction
exists. When the malfunction in dicator is illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a variety of reasons,
including the installation of re placement or alternate tires or wheels on the vehicle that
prevent the TPMS (tire pressure warning sy stem) from functioning properly. Always
check the TPMS (tire pressure warning system ) malfunction telltale after replacing one
or more tires or wheels on yo ur vehicle to ensure that the replacement or alternate tires
and wheels allow the TPMS (tir e pressure warning system) to continue to function prop-
erly.
NOTICE
■To ensure the tire pressure warning system operates properly
Do not install tires with differ ent specifications or makers, as the tire pressure warning
system may not operate properly.

3367-2. Steps to take in an emergency
■When the battery is removed or dis-
charged
●Side window open/close function linked
to door operation does not operate.
When closing the side window, slowly
close the side window while pushing the
upper portion of the side window
inside the soft top roof.
●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.378)
■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
●Immediately after replacing the battery,
fully open or close the soft top roof, as the
luggage cover may be half-opened.
●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 disconnecting the bat-
tery, turn the engine switch off.
If you are unsure wh at mode the engine
switch was in before the battery dis-
charged, be especially careful when
reconnecting the battery.
●If the battery discharges, it may not be
possible to shift the shift position to other
positions. In this case, the vehicle cannot
be towed without lifting both rear wheels
because the rear wheels will be locked.
(  P.310)
■When replacing the battery
●Use a Central Degassing type battery
(European Regulations).
●Use a battery that the case size is same as
the previous one (LN4), 20 hour rate
capacity (20HR) is eq uivalent (80Ah) or
greater, and performance rating (CCA)
is equivalent (685A) 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 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 exchanging, firmly attach the fol-
lowing items to the exhaust hole of the
battery.
• Use the exhaust hose that was attached to the battery before exchanging.
• Use the exhaust hole plug included with the battery exchanged or the one

system is turned on immediately after a
cold start. Confirm that the fan is operating
by checking the fan sound and air flow. If it
is difficult to check these, turn the air con-
ditioning system on and off repeatedly.
(The fan may not operate in freezing tem-
peratures.)
7If the fan is not operating:
Stop the engine immediately and
contact your Lexus dealer.
If the fan is operating:
Have the vehicle inspected at the
nearest Lexus dealer.

WARNING
■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.
●While the engine and radiator are hot,
do not loosen or remove the coolant
inlet cap or coolant reservoir cap.
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.

3628-1. Specifications
■Treadwear
The treadwear grade is a comparative
rating based on the wear rate of the
tire when tested under controlled con-
ditions on a specified government test
course.
For example, a tire graded 150 would
wear one and a half (1 - 1/2) times as well
on the government course as a tire graded
100.
The relative performa nce of tires depends
upon the actual conditions of their use.
Performance may differ significantly from
the norm due to variatio ns in driving habits,
service practices and differences in road
characteristics and climate.
■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 properly 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.

AVERTISSEMENT
●Ne fixez et n’appuyez rien sur des
zones telles que la planche de bord, le
tampon de volant ou encore la partie
inférieure du tableau de bord.
Ces objets peuvent se transformer en
projectiles lorsque les coussins gonfla-
bles SRS du conducteur, du passager
avant et de protection des genoux se
déploient.
●Ne fixez rien sur des zones telles que
les portières, le pare-brise, les glaces
latérales, les montants avant ou
arrière, et le brancard de pavillon.
●N’accrochez pas de cintres ni d’autres
objets rigides sur les crochets porte-
vêtements. Tous ces objets pourraient
se transformer en projectiles et vous
occasionner des blessures graves,
voire mortelles, en cas de déploiement
des coussins gonflables SRS en rideau.
●Si un recouvrement de vinyle est placé
sur la zone de déploiement du coussin
gonflable SRS de protection des
genoux, veillez à le retirer.
●N’utilisez pas d’accessoires recou-
vrant les parties du siège où les couss-
ins gonflables SRS latéraux se
déploient, car ces accessoires pour-
raient entraver le déploiement des
coussins gonflables SRS. De tels
accessoires peuvent empêcher les
coussins gonflables latéraux de se
déployer correctement, rendre le sys-
tème inopérant ou provoquer acci-
dentellement le déploiement des
coussins gonflables latéraux, occa-
sionnant des blessures graves, voire
mortelles.
●Ne frappez pas et n’appliquez pas une
pression importante à l’emplacement
des portières ou des composants des
coussins gonflables SRS.
Cela peut provoquer un mauvais
fonctionnement des coussins gonfla-
bles SRS.
●Ne touchez à aucun composant des
coussins gonflables SRS immédiate-
ment après leur déploiement (gon-
flage), 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
frais, ou quittez le véhicule si vous pou-
vez 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 avant et arrière, sont endom-
magés ou fissurés, faites-les remplacer
par votre concessionnaire Lexus.
●Ne placez aucun objet, par exemple
un coussin, sur le siège du passager
avant. Cela disperse rait le poids du
passager, ce qui empêcherait le cap-
teur de le détecter correctement. Cela
pourrait empêcher le déploiement des
coussins gonflables SRS du passager
avant en cas de collision.
