Starting difficulties
If the SmartKey is left in starter switch
position 0 for an extended period of time,
it can no longer be turned in the switch. In
this case, the steering is locked.
To unlock remove SmartKey from the
starter switch and reinsert.
If the engine does not start as described,
carry out the following steps:
If you are starting the engine with the
SmartKey, turn SmartKey in starter
switch to position 0 and repeat starting
procedure.
If you are starting the engine with
KEYLESS-GO: Close any doors that
may be open to allow for better detec-
tion of the SmartKey with
KEYLESS-GO.
Or:
Start the engine with the SmartKey as
radio signals from another source may
be interfering with the SmartKey with
KEYLESS-GO.
Repeat the starting procedure
( page 52). Remember that extended
starting attempts can drain the battery.
Get a jump start ( page 464).
If the engine does not start after several
starting attempts, there could be a mal-
function in the engine electronics or in the
fuel supply system.
