Before driving ●
To reduce key battery depletion when the
electronic key is to not be used for long
periods of time, set the electronic key to
the battery-saving mode. ( → P.108)●

that the electronic key battery may be
depleted. Replace the battery when nec-
essary. ( → P.403)
• The smart access system with push-but-
ton start or the wireless remote control

of the following electr ical appliances that
produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and
battery chargers
• Recharging cellular phones or cordless
