The smart access system with push-button st art uses weak radio wa ves. In the following
situations, the communication between the electronic key and the vehicle may be
affected, preventing the smar t access system with push-but ton start, wireless remote
control and engine immobilizer sy stem from operating properly.
(Ways of coping: → P. 546)●

objects
• Portable radio, cellular phone, cordle ss phone or other wireless communication
device
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
