5-2. Steps to take in an emergency
■Sealant
●One tire can be repaired using the bottle of sealant stored in the emergency tire
puncture repair kit.
●The sealant can be used when the outside temperature is from -22°F (-30°C)
to 140°F (60°C).
●When the outside temperature is low, the viscosity of the sealant becomes high
and it will be more difficult to inject th e sealant. In this case, warm the sealant in
the vehicle before using it.
●The sealant has a limited lifespan. The expi ration date is marked on the bottle.
The sealant should be replaced before the expiration date. Contact your Lexus
dealer.
●If the sealant gets on your clothes, it may stain.
●After using the sealant, bring the empty bottle of sealant to your Lexus dealer
and purchase a new bottle. Keep the ne w bottle of sealant in your vehicle.
■Compressor
●The compressor is a pneumatic filling type for passenger vehicles.
●When the compressor is operating, a loud operating noise will be produced.
This does not indicate a malfunction.
■The wheel of a tire that has been repaired
If you remove the sealant adhering to the wheel with a rag, you can reuse the wheel.
■The valve of a tire that has been repaired
●After a tire is repaired with the emergency tire puncture repair kit, the tire pres-
sure warning valve and transm itter should be replaced.
●After a tire is repaired with the emergency tire puncture repair kit, even if the
tire inflation pressure is at the recommended level, the tire pressure warning
light may come on/flash.

Start the engine of the second vehicle. Increase the engine speed
slightly and maintain at that level for approximately 5 minutes to
recharge the battery of your vehicle.
Maintain the engine speed of th e second vehicle and start the
engine of your vehicle.
Once the vehicle’s engine has started, remove the jumper cables
in the exact reverse order from which they were connected.
After disconnecting the jumper cables, make sure that the negative (-)
battery terminal on your vehicle is fixed securely.
Once the engine starts, have the vehicle inspected at your Lexus dealer
as soon as possible.
■Starting the engine when the battery is discharged
●If the gear indicator is not displayed when an attempt is made to start the
engine, the engine is not yet ready to start. Depress the brake pedal for several
seconds and wait for the ge ar indicator to appear.
●The engine cannot be started by push-starting.
■To prevent battery discharge
●Turn off the headlights and the audio system while the engine is off.
●Turn off any unnecessary electrical compon ents when the vehicle is running at a

CAUTION
■To prevent a vehicle fire
When connecting or disconnecting the jumper cables to or from the battery, make
sure that they are not in contact with any part made of CFRP (Carbon Fiber Rein-
forced Plastics). Failure to do so may cause a fire hazard.
■Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flammable
gas that may be emitted from the battery.
●Make sure each jumper cable is connecte d to the correct terminal and that it is
not unintentionally in contact with any part other than the intended terminal.
●Do not allow the + and - clamps of the jumper cables to come into contact with
each other.
●Do not smoke, use matches, cigarette lighters or allow open flame near the bat-
tery.
■Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while related parts
contain lead and lead compounds. Observe the following precautions when han-
dling the battery:
●When working with the battery, always we ar safety glasses and take care not to
allow any battery fluids (acid) to come into contact with skin, clothing or the vehi-
cle body.
●Do not lean over the battery.
●In the event that battery fluid comes into contact with the skin or eyes, immedi-
ately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention can be
received.
●Always wash your hands after handling the battery support, terminals, and other
battery-related parts.
●Do not allow children near the battery.

■Recommendation of the use of cleaner burning gasoline
Cleaner burning gasoline, including reformulated gasoline that contains oxygen-
ates such as ethanol or MTBE (Methyl Te rtiary Butyl Ether) is available in many
areas.
Lexus recommends the use of cleaner burning gasoline and appropriately blended
reformulated gasoline. These types of gasoline provide excellent vehicle perfor-
mance, reduce vehicle emissions and improve air quality.
■Non-recommendation of the use of blended gasoline
●Lexus allows the use of oxygenate blended gasoline where the oxygenate con-
tent is up to 10% ethanol or 15% MTBE.
●If you use gasohol in your vehicle, be sure that it has an octane rating no lower
than 87.
●Lexus does not recommend the use of gasoline containing methanol.
■Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an octane enhancing additive called MMT (Methylcyclo-
pentadienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gasoli ne that contains MMT. If fuel contain-
ing MMT is used, your emission control system may be adversely affected.
The malfunction indicator lamp on the inst rument cluster may come on. If this hap-
pens, contact your Lexus dealer for service.
■If your engine knocks
●Consult your Lexus dealer.
●You may occasionally notice light knocking for a short time while accelerating
or driving uphill. This is normal and there is no need for concern.
