CAUTION
■SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
●The driver and all passengers in the vehicle must wear their seat belts properly.
The SRS airbags are supplemental devices to be used with the seat belts.
●The SRS driver airbag deploys with consider able force, and can cause death or seri-
ous injury especially if the driver is very close to the airbag. The National Highway
Traffic Safety Administration (NHTSA) advises:
Since the risk zone for the driver’s airbag is the first 2 - 3 in. (50 - 75 mm) of inflation,
placing yourself 10 in. (250 mm) from your driver airbag provides you with a clear
margin of safety. This distance is measured from the center of the steering wheel to
your breastbone. If you sit less than 10 in. (250 mm) away now, you can change your
driving position in several ways:
• Move your seat to the rear as far as you can while still reaching the pedals com- fortably.
• Slightly recline the back of the seat. Although vehicle designs vary, many drivers can achieve the 10 in. (250 mm) dis-
tance, even with the driver seat all the wa y forward, simply by reclining the back of
the seat somewhat. If reclining the back of your seat makes it hard to see the road,
raise yourself by using a firm, non-slippery cushion, or raise the seat if your vehicle
has that feature.
• If your steering wheel is ad justable, tilt it downward. This points the airbag toward
your chest instead of your head and neck.
The seat should be adjusted as recommen ded by NHTSA above, while still maintain-
ing control of the foot pedals, steering whee l, and your view of the instrument panel
controls.

■Tire inflation pressure
●It may take a few minutes to display the tire inflation pressure after the engine switch is
turned to IGNITION ON mode. It may also take a few minutes to display the tire infla-
tion pressure after inflation pressure has been adjusted.
●“---” may be displayed if the tire information cannot be determined due to unfavorable
radio wave conditions.
●Tire inflation pressure changes with temperature. The displayed values may also be dif-
ferent from the values measured using a tire pressure gauge.
■Liquid crystal display
P. 8 4
CAUTION
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal information
display. At extremely low temperatures, th e information display monitor may respond
slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear number
appearing on the display. This lag could cau se the driver to downshift again, causing
rapid and excessive engine braking and po ssibly an accident resulting in death or
injury.
■Cautions during setting up the display
As the engine needs to be running during sett ing up the display, ensure that the vehicle
is parked in a place with adequate ventila tion. In a closed area such as a garage,
exhaust gases including harmful carbon monoxide (CO) may collect and enter the
vehicle. This may lead to death or a serious health hazard.
NOTICE
■During setting up the display
To prevent battery discharge, ensure that th e engine is running while setting up the dis-
play features.
