Driving the vehicle until the fuel tank is
empty is not recommended. Otherwise, air
may be sucked into the fuel system. If this
happens, the ? malfunction indicator
lamp (USA only) or the ± malfunction
indicator lamp (Canada only) comes on
and the engine may not start immediately
after refueling the vehicle.

̈ Make sure the automatic transmission
is set to P.
The gear position indicator in the multi-
function display should be on
P

̈ Do not depress the accelerator.
̈ Turn the SmartKey in the starter switch
to position 2 for at least 10 seconds
(

̈ Return the SmartKey in the starter
switch to position 0 (
୴ page 40).
̈ Turn the SmartKey in the starter switch
to position 3 (

there for a maximum of 40 seconds or
until the engine runs surge-free.

̈ Turn the SmartKey in the starter switch
to position 3 (
