If a tire is flat

Precautions for when you have a flat tire

Your vehicle is not equipped with a spare tire, but instead you can continue driving
the vehicle with run-flat tires even if any tire goes flat. In this case, slow down and
drive with extra caution.
Take your vehicle to the nearest Lexus dealer or authorized tire dealer as soon as
possible if any tire goes flat.
The vehicle can be driven for a maximum of 50 miles (80 km) at a speed below
50 mph (80 km/h) after the tire pressure warning light comes on.

A run-flat tire has a

mark on the side wall.

INFORMATION

■

In some conditions (such as at high temperatures)

You cannot continue driving for up to 50 miles (80 km).

NOTICE

■

When replacing the tires

When removing or fitting the wheels, tires or the tire pressure warning valve and
transmitter, contact your Lexus dealer as the tire pressure warning valve and transmitter
may be damaged if not handled correctly.

■

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.

When a malfunction occurs during charging

The indicators on the CCID (Charging Circuit Interrupting Device) use a
combination of different statuses (not illuminated, illuminated or flashing) to
inform the user of internal malfunctions.

When the error warning indicator is illuminated or flashing, temporarily remove the plug
from the outlet and then reconnect it to check if the error indicator turns off.
If the error warning indicator turns off, charging is now possible. If it does not turn off,
perform the correction procedure in the following chart.
