■The compact spare tire (vehicles with a compact spare tire)
●The compact spare tire is identified by the label “TEMPORARY USE ONLY” on the
tire sidewall. Use the compact spare tire temporarily, and only in an emergency.
●Make sure to check the tire inflation pressure of the compact spare tire. (P. 737)
■When using the compact spare tire (vehicles with a compact spare tire)
As the compact spare tire is not equipped with a tire pressure warning valve and trans- mitter, low inflation pressure of the spare tire will not be indicated by the tire pressure
warning system. Also, if you replace the compact spare tire after the tire pressure warn- ing light comes on, th e light remains on.
■When the compact spare tire is equipped (vehicles with a compact spare tire)
When driving with the compact spare tire installed, the vehicle height will be different than when driving with standard tires.
■If you have a flat front tire on a road covered with snow or ice (vehicles with a compact
spare tire)
Install the compact spare tire on one of the rear wheels of the vehicle. Perform the follow- ing steps and fit tire chains to the front tires:
Replace a rear tire with the compact spare tire.
Replace the flat front tire with the tire removed from the rear of the vehicle.
Fit tire chains to the front tires.

■Emergency tire puncture repair kit
●The sealant has a limited life span. The expiry date is marked on the bottle. The sealant should be replaced before the expiry da te. Contact any authorized Lexus dealer or repairer, or another duly qualified an d equipped professional for replacement.
●The sealant stored in the emergency tire puncture repair kit can be used only once to temporarily repair a single tire. If the seal ant has been used and needs to be purchased, contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional. The compressor is reusable.
●The compressor can be used repeatedly.
●The sealant can be used when the outside temperature is from -40 C (-40F) to 60C
(140 F).
●The kit is exclusively designed for size and type of tires originally installed on your vehi- cle. Do not use it for tires that a different size than the original ones, or for any other
purposes.
●If the sealant gets on your clothes, it may stain.
●If the sealant adheres to a wheel or the surface of the vehicle body, the stain may not be
removable if it is not cleaned at once. Immediately wipe away the sealant with a wet cloth.
●During operation of the kit, a loud operatio n noise is produced. This does not indicate a
malfunction.
●Do not use to check or to adjust the tire pressure.
■If the tire is inflated to mo re than the recommended level
Disconnect the hose from the valve.
Disconnect the hose from the valve, remove the air release cap from the hose and then reconnect the hose.
Turn the compressor switch on and wait for several seconds, then turn it off. Check that
the air pressure indicator sh ows the recommended level. (P. 737) If the air pressure is lower than the reco mmended level, turn the compressor switch on again and repeat the inflation procedure un til the recommended pressure is reached.
■After a tire repaired with the emergency tire puncture repair kit
●The tire pressure warning valve and transmitter should be replaced.
●Even if the tire inflation pressure is at the recommended level, the tire pressure warning
light may come on/flash.
Install the air release cap to the end of the
hose and push the protrusion on the air release cap into the valve to let some air out.

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.
Open and close any of the doors of your vehicle with the engine switch off.
Maintain the engine speed of the second vehicle and start the engine of your
vehicle by turning the engine switch to IGNITION ON mode.
Once the vehicle’s engine has started, remove the jumper cables in the exact
reverse order from which they were connected.
Once the engine starts, have the vehicle inspected at any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional as soon
as possible.
■Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■To prevent battery discharge
●Turn off the headlights and the audio system while the engine is stopped. (RX200t: Except when the engine is stopped by the Stop & Start system.)
●Turn off any unnecessary electrical components when the vehicle is running at a low
speed for an extended period, such as in heavy traffic.
■Charging the battery
The electricity stored in the battery will discharge gradually even when the vehicle is not
in use, due to natural discharge and the draining effects of certain electrical appliances. If the vehicle is left for a long time, the battery may discharge, and the engine may beunable to start. (The battery recharges automatically during driving.)
■When the battery is removed or discharged
●In some cases, it may not be possible to unlock the doors using the smart entry & startsystem when the battery is discharged. Us e the wireless remote control or the mechan-
ical 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 discharged. Before disconnecting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery discharged, be especially careful when reconnecting the battery.
●Vehicles with power back door: The power back door must be initialized. (P. 159)
●RX200t: After the battery terminals have been disconnected then reconnected or the battery has been replaced, the Stop & Start system may not automatically stop theengine for approximately 5 to 60 minutes.
