Keys
{ WARNING:
Leaving children in a vehicle with the ignition key
is dangerous for many reasons, children or others
could be badly injured or even killed. They could
operate the power windows or other controls or
even make the vehicle move. The windows will
function with the keys in the ignition and children
could be seriously injured or killed if caught in the
path of a closing window. Do not leave the keys in
a vehicle with children.
The key can be used for the ignition, the driver's door,
and the glovebox lock.
The key has a bar-coded key tag that the dealer or
qualified locksmith can use to make new keys. Store
this information in a safe place, not in your vehicle.
See your dealer if a replacement key or additional key
is needed.
Notice: If you ever lock your keys in the vehicle,
you may have to damage the vehicle to get in. Be
sure you have spare keys.
