(a) Simple checks
Before making these checks, make sure
you have followed the correct starting
procedure given in "How to start the
hybrid system" on page 230 and that you
have sufficient fuel. Also check whether
the other keys will start the
system. If they work, your key may be
broken. Have the key checked at your
Toyota dealer. If none of your keys work,
there may be a malfunction in the hybrid
vehicle immobilizer system. Call
Toyota dealer. (See "Keys" on page 18.)

(b) Jump starting
If the auxiliary battery is discharged,
the hybrid system can be started by
jump starting. Depending on the vehicle
condition, the engine may not start.
To avoid serious personal injury and
damage to your vehicle which might re-
sult from battery explosion, acid burns,
electrical burns, or damaged electronic
components, these instructions must be
followed precisely.
If the auxiliary battery is discharged, you
cannot access to the auxiliary battery in
the luggage compartment because
back door cannot be opened. Use the ex-
clusive jump starting terminal in the en-
gine compartment. For details, see "JUMP
STARTING PROCEDURE" on page 239.
NOTICE
If the auxiliary battery is discharged
with the transaxle in "P", your vehicle
cannot be moved unless the front
wheels are raised. This is because the
front wheels are locked by means of
the parking lock mechanism.
If you are unsure about how to follow this
procedure, we strongly recommend that
you seek the help of a competent qualified
technician or towing service.
