How to Set the Distance Between
Vehicles During Headway Control
The distance between vehicles is set to a
shorter distance each time the
switch is
pressed. The distance between vehicles is
set to a longer distance by pressing the
switch. The distance-between-vehicles can
be set to 4 levels; Long, medium, short,

ft))
Medium (about 40 m
(131 ft))
Short (about 30 m (98
ft))
Extremely short (about
25 m (82 ft))
NOTE
 y  The distance between vehicles differs
depending on the vehicle speed, and the
slower the vehicle speed, the shorter the
distance.
 y When the ignition is switched to ACC
or OFF and then the engine is started
again, the system automatically sets
the distance between vehicles to the
previous setting.
Changing the Set Vehicle Speed

When Driving
Tire Pressure Monitoring System
Tire Pressure Monitoring System *
The Tire Pressure Monitoring System (TPMS) monitors the air pressure of all\
four tires. If
the air pressure of one or more tires is too low, the system warns the driver by indicating the
tire pressure monitoring system warning light in the instrument cluster \
and operating a beep
sound. The system monitors the tire pressures indirectly using the data sent fr\
om the ABS
wheel speed sensors.
To allow the system to operate correctly, the system needs to be initialized with the specifi ed
tire pressure (value on the tire pressure label). Follow the procedure\
and perform the
initialization.
Refer to Tire Pressure Monitoring System Initialization on page 4-107 .
The warning light fl ashes when the system has a malfunction.
