When trouble arises
WARNING
QIf a blowout or sudden air leakage
should occur
The tire pressure warning system may
not activate immediately.
QMaintenance of the tires
Each tire, including the spare (if pro-
vided), should be checked monthly when
cold and inflated to the inflation pressure
recommended by the vehicle manufac-
turer on the vehicle placard or tire infla-
tion pressure label (tire and load
information label). (If your vehicle has
tires of a different size than the size indi-
cated on the vehicle placard or tire infla-
tion pressure label [tire and load
information label], you should determine
the proper tire inflation pressure for
those tires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS-tire pressure
warning system) that illuminates a low
tire pressure telltale (tire pressure warn-
ing light) when one or more of your tires
is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale
(tire pressure warning light) illuminates,
you should stop and check your tires as
soon as possible, and inflate them to the
proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire
to overheat and can lead to tire failure.
Under-inflation also reduces fuel effi-
ciency and tire tread life, and may affect
the vehicle’s handling and stopping abil-
ity.
Please note that the TPMS (tire pressure
warning system) is not a substitute for
proper tire maintenance, and it is the
driver’s responsibility to maintain correct
tire pressure, even if under-inflation has
not reached the level to trigger illumina-
tion of the TPMS low tire pressure telltale
(tire pressure warning light).
Your vehicle has also been equipped
with a TPMS (tire pressure warning sys-
tem) malfunction in dicator to indicate
when the system is not operating prop-
erly. The TPMS (tire pressure warning
system) malfunction indicator is com-
bined with the low tire pressure telltale
(tire pressure warning light). When the
system detects a malfunction, the telltale
will flash for approximately one minute
and then remain continuously illumi-
nated. This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists. When the mal-
function indicator is illuminated, the sys-
tem 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 th e installation of
replacement or alternate tires or wheels
on the vehicle that prevent the TPMS
(tire pressure warning system) from
functioning properly. Always check the
TPMS (tire pressure warning system)
malfunction telltale after replacing one
or more tires or wheels on your vehicle
to ensure that the replacement or alter-
nate tires and wheels allow the TPMS
(tire pressure warning system) to con-
tinue to function properly.
NOTICE
QTo ensure the tire pressure warning
system operates properly
Do not install tires wi th different specifi-
cations or makers, as the tire pressure
warning system may not operate prop-
erly.

6Open and close any of the doors of
your vehicle with the power switch
off.
7 Maintain the engine speed of the
second vehicle and start the hybrid
system of your vehicle by turning
the power switch to ON mode.
8 Make sure the “READY” indicator
comes on. If the indicator does not
come on, contact your Lexus
dealer.
9 Once the vehicle’s hybrid system
has started, remove the jumper
cables in the exact reverse order
from which they were connected.
10 Close the exclusive jump starting
terminal cover, and reinstall the
fuse box cover to its original posi-
tion.
Once the hybrid system starts, have the
vehicle inspected at your Lexus dealer as
soon as possible.
QStarting the hybrid system when the 12-
volt battery is discharged
The hybrid system cannot be started by
push-starting.
QTo prevent 12-volt battery discharge
OTurn off the headlights and the audio sys-
tem while the hybrid system is stopped.
OTurn off any unnecessary electrical com-
ponents when the vehicle is running at a
low speed for an extended period, such
as in heavy traffic.
QWhen the 12-volt battery is removed or
discharged
OInformation stored in the ECU is cleared.
When the 12-volt battery is depleted,
have the vehicle inspected at your Lexus
dealer.
OSome systems may require initialization.
(  P.433)
QWhen removing the 12-volt battery ter-
minals
When the 12-volt battery terminals are
removed, the information stored in the
ECU is cleared. Before removing the 12-
volt battery terminals, contact your Lexus
dealer.
QCharging the 12-volt battery
The electricity stored in the 12-volt battery
will discharge gradually even when the
vehicle is not in use, due to natural dis-
charge and the draining effects of certain
electrical appliances. If the vehicle is left for
a long time, the 12-volt battery may dis-
charge, and the hybrid system may be
unable to start. (The 12-volt battery
recharges automatically while the hybrid
system is operating.)
QWhen recharging or replacing the 12-
volt battery
OIn some cases, it may not be possible to
unlock the doors using the smart access
system with push-button start when the
12-volt battery is discharged. Use the
wireless remote control or the mechani-
cal key to lock or unlock the doors.
OThe hybrid system may not start on the
first attempt after the 12-volt battery has
recharged but will start normally after the
second attempt. This is not a malfunction.
OThe power switch mode is memorized by
the vehicle. When the 12-volt battery is
reconnected, the system will return to the
mode it was in before the 12-volt battery
was discharged. Before disconnecting
the 12-volt battery, turn the power switch
off.
If you are unsure what mode the power
switch was in before the 12-volt battery
discharged, be especially careful when
reconnecting the 12-volt battery.
QWhen replacing the 12-volt battery
OUse a 12-volt battery that conforms to
European regulations.
OUse a 12-volt battery that the case size is
same as the previous one (LN2), 20 hour
rate capacity (20HR) is equivalent
(60Ah) or greater, and performance rat-
ing (CCA) is equivalent (563A) or
greater.

as soon as possible.
6After stopping the hybrid system
and waiting for 5 minutes or more,
start the hybrid system again and
check if “Hybrid system over-
heated Output power reduced” is
shown on the multi-information dis-
play.
If the message does not disappear:
Stop the hybrid system and contact your
Lexus dealer.
If the message is not displayed:
The hybrid system temperature has
dropped and the vehicle may be driven
normally.
However, if the message appears again
frequently, contact your Lexus dealer.
WARNING
QWhen inspecting under the hood of
your vehicle
Observe the following precautions.
Failure to do so may result in serious
injury such as burns.
OIf 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.
OAfter the hybrid system has been
turned off, check that the “READY”
indicator are off.
When the hybrid system is operating,
the gasoline engine may automatically
start, or the cooling fan may suddenly
operate even if the gasoline engine
stops. Do not touch or approach rotat-
ing parts such as the fan, which may
lead to fingers or clothing (especially a
tie, a scarf or a muffler) getting caught,
resulting in serious injury.
ODo not loosen the coolant inlet cap or
coolant reservoir caps while the hybrid
system and radiator are hot.
High temperature steam or coolant
could spray out.
NOTICE
QWhen adding engine/power control
unit coolant
Add coolant slowly after the hybrid sys-
tem has cooled down sufficiently. Adding
cool coolant to a hot hybrid system too
quickly can cause damage to the hybrid
system.
QTo prevent damage to the cooling
system
Observe the following precautions:
OAvoid contaminating the coolant with
foreign matter (such as sand or dust
etc.).
ODo not use any coolant additive.

4168-1. Specifications
QTraction 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.
QTemperature 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 sudden tire failure.
Grade C corresponds to a level of perfor-
mance which all passenger car tires must
meet under the Federal 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, underinflation, or exces-
sive loading, either separately or in combi-
nation, can cause heat buildup and
possible tire failure.

AVERTISSEMENT
ONe 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.
ONe fixez rien sur des zones telles que
les portières, le pare-brise, les glaces
latérales, les montants avant ou
arrière, le brancard de pavillon et la
poignée de maintien.
ON’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.
OSi un recouvrement de vinyle est placé
sur la zone de déploiement du coussin
gonflable SRS de protection des
genoux, veillez à le retirer.
ON’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.
ONe frappez pas et n’appliquez pas une
pression importante à l’emplacement
des portières avant ou des com-
posants des coussins gonflables SRS.
Cela peut provoquer un mauvais
fonctionnement des coussins gonfla-
bles SRS.
ONe touchez à aucun composant des
coussins gonflables SRS immédiate-
ment après leur déploiement (gon-
flage), car ils pourraient être chauds.
OSi 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.
