Do not press the buttons on the remote control vehicle key unless you actually want to use the 
function in question. Since terrain and conditions vary, pressing a button on the remote control vehicle 
key when it is not necessary may unlock the vehicle or set off the panic alarm, even if you think you 
are out of range. 
  Remote control vehicle key functions can be temporarily disrupted by interference from transmit-
ters near the vehicle that use the same frequency range (such as radio equipment or cellular phones). 
  Things between the remote control vehicle key and vehicle, bad weather, as well as a weak 
battery can reduce the operating range. 
  If the remote control vehicle key buttons  47 or the power locking buttons  48 are pushed re-
peatedly in quick succession, the power locking system is switched off for a brief period to help keep it 
from being overloaded. The vehicle is then unlocked for about 30 seconds. Unless a door or the 
luggage compartment lid is opened in this span of time, the vehicle is automatically locked afterwards.
