carry out the following steps:
If you are starting the engine with the
SmartKey, turn SmartKey in starter
switch to position0 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

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 49). Remember that extended
starting attempts can drain the battery.
Get a jump start (
