▼Door-Ajar/Liftgate-Ajar Warning
Indication/Warning Light
The light turns on if any door/liftgate is
not closed securely.
Action to be taken
Close the door/liftgate securely.
▼Tire Pressure Monitoring System
(TPMS) Warning Indication/
Warning Light (Turns on)
If a tire pressure decreases below the
specified air pressure, the TPMS
warning light turns on.
At the same time, a message and the
tire pressure of each tire are displayed
on the multi-information display
alternately. In addition, the tire (s) with
low air pressure is displayed in yellow.
WARNING
Do not drive the vehicle at high
speeds if the TPMS warning light turns
on or
flashes:
Driving the vehicle at high speeds
while the TPMS warning light is turned
on or flashing is dangerous because
the brake performance and the
steering wheel operability will be
reduced. If the vehicle is driven at high
speeds or the brakes are suddenly
applied, it could lead to an accident.
Gradually apply the brakes to lower the
vehicle's speed.
Do not ignore the TPMS warning light
when it is turned on or flashing:
Continuing to driv e the vehicle while
ignoring the illumi nation/flashing of
the TPMS warning light is dangerous
because a tire may burst which could
lead to an accident. Take appropriate
measures as soon as possible.
NOTE
While the TPMS is learning the tire
positions, such as immediately after a
tire position has been changed, the tire
pressure at the tire position prior to it
being changed is displayed until the
system completes the learning. For this
reason, the tire pressures displayed for
the tire positions may be different from
the actual tire pressures at the tire
positions.
Action to be taken
Adjust the tire pressures to the
appropriate pressures.
Refer to Tire Inflation Pressure on page
6-31.
