03 SIENNA_U (L/O 0207) If you lose your keys CAUTION Use extreme caution when towing vehicles. Avoid sudden starts or erratic driving maneuvers which would place excessive stress on the emergency towing eyelets and towing cable or chain. The eyelets and towing cable or chain may break and cause serious injury or damage. You can purchase a new key at your Toyota dealer if you can give them the key number. If your vehicle is equipped with the engine immobiliser system, the dealer will also need your master key. Vehicles with engine immobiliser system- Even if you lose only one key, contact your Toyota dealer to make a new key. If you lose all your master keys, you cannot make new keys; the whole engine immobiliser system must be replaced. See the suggestion given in "Keys" in Section 1−2. If your keys are locked in the vehicle and you cannot get a duplicate, many Toyota dealers can still open the door for you, using their special tools. If you must break a window to get in, we suggest breaking the smallest side window because it is the least expensive to replace. Be extremely cautious to avoid cuts from the glass. If you lose your wireless remote control transmitter Please contact your nearest Toyota dealer and you can purchase a new wireless remote control transmitter. Have the registered identification numbers of your transmitters deleted from your vehicle by your Toyota dealer as soon as possible to avoid the possibility of theft or an accident. Then, have the identification number of your new transmitter registered. At the same time, you must bring all of the remaining transmitters to have them registered again as well. You can use the wireless remote control system with the new transmitter. Contact your Toyota dealer for detailed information. NOTICE Use only a cable or chain specifically intended for use in towing vehicles. Securely fasten the cable or chain to the towing eyelets provided. Before towing, release the parking brake and put the transmission in "N". The key must be in "ACC" (engine off) or "ON" (engine running). CAUTION If the engine is not running, the power assist for the brakes and steering will not work so steering and braking will be much harder than usual. 2003 MY SIENNA (OM45410U) 271
