2004 Toyota Sienna Navigation Manual - Page 193

04 SIENNA_U (L/O 0408) To protect items locked in the glove box when using valet parking, leave the sub key with the attendant. Since the front doors and sliding doors can be locked without a key, you should always carry a spare master key in case you accidentally lock your keys inside the vehicle. NOTICE When using a key containing a transponder chip, observe the following precautions: z When starting the engine, do not use the key with a key ring resting on the key grip and do not press the key ring against the key grip. Otherwise the engine may not start, or may stop soon after it starts. z When starting the engine, do not use the key with other transponder keys around (including keys of other vehicles) and do not press other key plates against the key grip. Otherwise the engine may not start, or may stop soon after it starts. If this happens, remove the key once and then insert it again after removing other transponder keys (including keys of other vehicles) from the ring or while gripping or covering them with your hand to start the engine. 11 2004 SIENNA from Aug. '04 Prod. (OM45422U)
