■Replacing a flat tire
●Do not touch the disc wheels or the area around the brakes immediately after the
vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around the brakes will
be extremely hot. Touching these areas with hands, feet or other body parts while
changing a tire, etc. may result in burns.
●Failure to follow these precautions could cause the wheel nuts to loosen and the tire
to fall off, resulting in death or serious injury.
• Never use oil or grease on the wheel bolts or wheel nuts.Oil and grease may cause the wheel nuts to be excessively tightened, leading to
bolt or disc wheel damage. In addition, the oil or grease can cause the wheel nuts
to loosen and the wheel may fall off, causing a serious accident. Remove any oil or
grease from the wheel bolts or wheel nuts.
• Have the wheel nuts tightened with a torque wrench to 76 ft•lbf (103 N•m, 10.5 kgf•m) as soon as possible after changing wheels.
• When installing a tire, only use wheel nuts that have been specifically designed for
that wheel.
• If there are any cracks or deformations in the bolt screws, nut threads or bolt holes of the wheel, have the vehicle inspected by your Lexus dealer.

GS350_200t_GS F_OM_OM30E86U_(U)
Firmly tighten each wheel nut two or
three times in the order shown in the
illustration.
Tightening torque:
76 ft•lbf (103 N•m, 10.5 kgf•m)
Stow the flat tire, tire jack and all tools.
■The spare tire
●GS350/GS200t: The spare tire is identified by the label “TEMPORARY USE ONLY”
on the tire sidewall.
●Use the spare tire temporarily, and only in an emergency.
●Make sure to check the tire inflation pressure of the spare tire. (→P. 5 5 0 )
■When using the spare tire
As the spare tire is not equipped with a tire pressure warning valve and transmitter, low
inflation pressure of the spare tire will not be indicated by the tire pressure warning sys-
tem. Also, if you replace the spare tire after the tire pressure warning light comes on, the
light remains on.
■When the spare tire is equipped
The vehicle may become lower when driving with the spare tire compared to when driv-
ing with standard tires.
■If you have a flat rear tire on a road covered with snow or ice (vehicles with front and
rear tires of the same size)
Install the compact spare tire on one of the front wheels of the vehicle. Perform the fol-
lowing steps and fit tire chains to the rear tires:
Replace a front tire with the compact spare tire.
Replace the flat rear tire with the tire removed from the front of the vehicle.
Fit tire chains to the rear tires.

■Emergency tire puncture repair kit
●The sealant has a limited lifespan. The expiry date is shown on the bottle. The sealant
should be replaced before the expiry date. Contact your Lexus dealer 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 sealant has been used and need to be purchased,
contact your Lexus dealer.
●The sealant can be used when the outside temperature is from -40 °F (-40 °C) to
140 °F (60 °C).
●The repair kit is exclusively designed for size and type of tires originally installed on your
vehicle. 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 repair kit, a loud operation noise is produced. This does not
indicate a malfunction.
●Do not use the emergency tire puncture repair kit to check or to adjust the tire pres-
sure.
■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, and then turn it off. Check
that the air pressure indicator shows the recommended level. ( →P. 5 5 0 )
If the air pressure is lower than the recommended level, turn the compressor switch on
again and repeat the inflation procedure until the recommended pressure is reached.
■The valve of a tire that has been repaired
●After a tire is repaired with the emergency tire puncture repair kit, the valve should be
replaced.
●After a tire is repaired with the emergency tire puncture repair kit, even if the tire infla-
tion pressure is at the recommended level, the tire pressure warning light may come
on/flash.
■Note for checking the emergenc y tire puncture repair kit
Check the sealant expiry date occasionally.
The expiry date is shown on the bottle.
Do not use sealant whose expiry date has already passed. Otherwise, repairs conducted
using the emergency tire puncture repair kit may not be performed properly. Install the air release cap to the end of the
hose and push the protrusion on the air
release cap into the tire valve to let some air
out.

■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 off.
●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 be
unable to start. (The battery recharges automatically during driving.)
■When recharging or replacing the battery
●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 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.

■Recommendation of the use of gasoline containing detergent additives
●Lexus recommends the use of gasoline that contains detergent additives to avoid the
build-up of engine deposits.
●All gasoline sold in the U.S.A. contains
minimum detergent additives to clean and/or
keep clean intake systems, per EPA’s lowest additives concentration program.
●Lexus strongly recommends the use of Top Tier Detergent Gasoline. For more informa-
tion on Top Tier Detergent Gasoline and a list of marketers, please go to the official
website www.toptiergas.com.
■Recommendation of the use of low emissions gasoline
Gasolines containing oxygenates such as ethers and ethanol, as well as reformulated
gasolines, are available in some cities. These fuels are typically acceptable for use, pro-
viding they meet other fuel requirements.
Lexus recommends these fuels, since the formulations allow for reduced vehicle emis-
sions.
■Non-recommendation of the use of blended gasoline
●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 enhanc ing additive called MMT (Methylcyclopenta-
dienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gasoline that contains MMT. If fuel containing
MMT is used, your emission control system may be adversely affected.
The malfunction indicator lamp on the instrument cluster may come on. If this happens,
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 driv-
ing uphill. This is normal and there is no need for concern.
●Use only gasoline containing up to 15% etha-
nol.
DO NOT use any flex-fuel or gasoline that
could contain more than 15% ethanol, includ-
ing from any pump labeled E30, E50, E85
(which are only some examples of fuel con-
taining more than 15% ethanol).DO NOT use gasoline con-
taining more than 15% ethanol.
