■Hybrid battery air vent
Hybrid battery air vent
There is an air intake vent on the
package tray for the purpose of
cooling the hybrid battery (trac-
tion battery). If the vent becomes
blocked, the hybrid battery may
overheat, leading to a reduction in
hybrid battery output.
Emergency shut off system
The emergency shut off system blocks off the high voltage current and
stops the fuel pump to minimize the risk of el ectrocution and fuel leakage
when a certain level of impact is detected by the impact sensor. If the
emergency shut off system activates, yo ur vehicle will not restart. To
restart the hybrid system, contact your Lexus dealer.
Energy monitor/consumption screen
You can view the status of your h ybrid system on the multi-information
display ( P. 155) and the touch screen ( P. 224). The following images
are examples only, and may vary slightly from actual conditions.

CAUTION
■Reclining adjustment
Do not recline the seat more than necessary when the vehicle is in motion, to
reduce the risk of sliding under the lap belt. 
If the seat is too reclined, during an accident the lap belt may slide past the hips and
apply restraint forces directly to the abdomen or your neck may contact the shoul-
der belt, increasing the risk of death or serious injury.
