7-2. Steps to take in an emergency
Take your vehicle to the nearest autho-
rized Lexus retailer or Lexus autho-
rized repairer, or any reliable repairer,
or authorized tire dealer as soon as
possible if any tire goes flat.
The vehicle can be driven for a maximum
of 160 km (100 miles) at a speed below 80
km/h (50 mph) after the tire pressure
warning light comes on. ( P.374)
A run-flat tire has a mark on the
side wall.
■In some condition (such as at high tem-
peratures)
You cannot continue driving for up to 160 km (100 miles).
■For the detailed information on run-flat tires
See the tire warranty booklet.
If you have a flat tire
Your vehicle is not equipped with a
spare tire, but instead you can con-
tinue driving the vehicle with run-
flat tires even if any tire goes flat.
In this case, slow down and drive
with extra caution.
Run-flat tires
NOTICE
■When replacing the tires
When removing or fitting the wheels, tires or the tire pressure warning valve and transmitter, contact any authorized
Lexus retailer or Lexus authorized repairer, or any reliable repairer as the tire pressure warning valve and transmit-
ter may be damaged if not handled cor- rectly.
■When driving over bumps
If a vehicle has a flat tire, the vehicle height will be lower than usual. Ensure
that nothing strikes the bottom of the vehicle.
■To avoid damaging the tire pressure warning valves and transmitters
When a tire is repaired with liquid seal-
ants, the tire pressure warning valve and transmitter may not operate properly. If a liquid sealant is used, contact any autho-
rized Lexus retailer or Lexus authorized repairer, or any reliable repairer or other qualified service shop as soon as possi-
ble. Make sure to replace the tire pres- sure warning valve and transmitter when replacing the tire. ( P.335)
