turned to ON mode. It may also take a few minutes to display the tire inflation pressure
after inflation pressure has been adjusted. ●
“---” may be displayed if the tire position information cannot be determined due to
unfavorable radio wave conditions. ●
Tire inflation pressure changes with temperat ure. The displayed values may also be dif-
ferent from the values measured using a tire pressure gauge.■
Liquid crystal display
Small spots or light spots may appear on the display. This phenomenon is characteristic
of liquid crystal displays, and there is no problem continuing to use the display.■

Caution for use while driving ●
When operating the multi-information display while driving, pay extra attention to the
safety of the area around the vehicle. ●
Do not look continuously at the multi-info rmation display while driving as you may fail
to see pedestrians, objects on the road, etc. ahead of the vehicle. ■
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 hybrid system needs to be operating during setting up the display, ensure that
the vehicle is parked in a place with adequate ventilation. In a closed area such as a
garage, exhaust gases includin g harmful carbon monoxide (CO) may collect and enter
the vehicle. This may lead to death or a serious health hazard.
NOTICE ■
While setting up the display
To prevent 12-volt battery discharge, ensure that the hybrid syst em is operating while
setting up the display features.

Electronic Key battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping the elec-
tronic key from receiving radio waves.
■
Conditions affe cting operation
The smart access system with push-button star t, wireless remote control and immobilizer
system use weak radio waves. In the followi ng situations, the communication between the
electronic key and the vehicle may be affected, preventing the smart access system with
push-button start, wireless remote control and immobilizer system from operating prop-
erly. (Ways of coping:  P. 5 6 4 )●
When the electronic key battery is depleted ●
Near a TV tower, electric powe r plant, gas station, radio stat ion, large display, airport or
other facility that generates strong radio waves or electrical noise ●
When the electronic key is in contact wi th, or is covered by the following metallic
objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins
•Hand warmers made of metal
• Media such as CDs and DVDs ●
When other wireless keys (that emit radio waves) are being used nearby ●
When carrying the electronic key together with the following devices that emit radio
waves
• Portable radio, cellular phone, cordless phone or other wireless communication
devices
• Another vehicle’s electronic key, another el ectronic key of your vehicle, or a wireless
key that emits radio waves
• Personal computers or person al digital assistants (PDAs)
• Digital audio players
• Portable game systems ●
If window tint with a metallic content or me tallic objects are attached to the rear win-
dow ●
