Noise from under vehicle after turning off the hybrid system

sound coming from under the vehicle for several minutes. This is the sound
of a fuel evaporation leakage check and, it does not indicate a malfunct\
ion.

cles are currently available in the market. You should know that Toyota does

Installation of a mobile two-way radio system
As the installation of a mobile two-way radio system in your vehicle could
affect electronic systems such as the multiport fuel injection system/sequen-
tial multiport fuel injection system, cruise control system, anti-lock brake sys-
tem, vehicle stability control system, SRS airbag system, seat belt
pretensioner system or hybrid system, be sure to check with your Toyota
dealer for precautionary measures or special instructions regarding installa-
tion.
High voltage parts and cables on the hybrid vehicles emit approximately the
same amount of electromagnetic waves as the conventional gasoline pow-
ered vehicles or home electronic appliances despite of their electromagnetic
shielding.
Unwanted noise may occur in the reception of the mobile two-way radio.
Scrapping of your Toyota
The SRS airbag and seat belt pretensioner devices in your Toyota contain
explosive chemicals. If the vehicle is scrapped with the airbags and seat belt
pretensioners left as they are, this may cause an accident such as fire. Be
sure to have the systems of the SRS airbag and seat belt pretensioner
removed and disposed of by a qualified service shop or by your Toyota
dealer before you scrap your vehicle.
Perchlorate Material
Special handling may apply, 
See www.dtsc.ca.gov/hazardouswaste/perchlorate.
Your vehicle has components that may contain perchlorate. These compo-
nents may include airbag, seat belt pretensioners, and wireless remote con-
trol batteries.

A message is automatically displaye d when a malfunction occurs in
the hybrid system or an impr oper operation is attempted.
If a warning message is shown on the multi-information display, read
the message and follow the instructions. ( P. 508)

the “READY” indicator does not come on, contact your Toyota dealer.
■ Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be
started, refuel the vehicle with at least enough gasoline to make the low fuel
level warning light go off (

the hybrid system may not be able to start. (The minimum amount of fuel to
add to make the low fuel level warning light go out is about 1.6 gal. [6.0 L,
1.3 Imp.gal.], when the vehicle is on a level surface. This value may vary
when the vehicle is on a slope.)
