Toyota Venza: Precaution




When disconnecting the cable from the negative (-) battery terminal, initialize the following systems after the cable is reconnected.

System Name

See Procedure

Back Door Closer System

Power Back Door System

(a) The power source mode (off, on (ACC), on (IG)) is always retained in memory by the vehicle. If the battery is disconnected, the power source mode that was present before disconnection will be restored after the battery is reconnected. Be sure to turn the engine switch off (change the power source mode to off) before disconnecting the cable from the negative battery terminal. Be careful if the power source mode of a vehicle with a discharged battery is not known.

(b) After the cable is reconnected to the negative (-) battery terminal, the engine may not start on the first attempt. This is not a malfunction. The engine will start normally for subsequent attempts.


In this chapter, the expression "power source" has been used in some locations to allow precise explanations. The power source mode is also expressed using conventional expressions such as "engine switch off", "engine switch on (ACC)" and "engine switch on (IG)".


(a) Before starting the engine, firmly depress the brake pedal until the indicator in the engine switch turns green.

(b) When a door is opened or closed after the engine switch is turned off, the steering wheel is locked by the steering lock function.


Do not turn off the engine switch during towing. Doing so will cause the steering wheel to be locked.

(c) If the engine is started and stopped repeatedly in a short amount of time, the steering lock motor operation may be limited to prevent overheating. In this case, do not start or stop the engine.


Operation will be re-enabled after approximately 10 seconds.

(d) When the steering lock has not released, the engine switch indicator light flashes green.


Operate the engine switch while turning the steering wheel to the left and right.

(e) The smart key system, wireless door lock control system and engine immobiliser system may not operate normally, or the size of the operation area may decrease in the following situations:

(1) When the smart key battery is depleted.

(2) When any facility that generates strong radio waves or electrical noise such as a TV tower, power plant, gas station, broadcast station, large video-billboard or airport are located near the inspection site.

(3) When the key is located near a wireless device such as a radio, cellular phone or cordless telephone.

(4) When the smart key is in contact with or covered with a metal object similar to the following:

  • Metal or aluminum plated card
  • Aluminum film from a cigarette box
  • Metallic wallet or bag
  • Coins
  • Heating pad
  • Media such as CDs or DVDs

(5) When a wireless remote is operated near the vehicle.

(6) When the key is carried with following items:

  • Electronic key or wireless remote from another vehicle
  • PC or similar handheld device
  • Digital audio player
  • Portable game device

(7) When a metallic film is applied to the rear glass.


(a) When the key battery is depleted, the engine cannot be started using the smart function. For how to start the engine when the key battery is depleted, see Description (See page ).

(b) If the electrical key is held near the engine switch to start the engine when the electrical key battery is depleted, the following warnings will sound:

(1) Driver door open → closed

  • An exit warning will sound if the shift lever is in a position other than P and the power source (engine switch) is in a mode other than off.
  • An exit warning will sound if the shift lever is in P and the power source is in a mode other than off.

(2) Doors other than the driver door open → closed

  • A warning will sound to indicate that the electrical key has been taken out of the vehicle.

These warnings will sound because it is not possible for the vehicle to determine if the key is present in the vehicle (due to the depleted key battery). These warnings do not indicate system malfunctions.


(a) If it is necessary to stop the engine in an emergency while driving the vehicle, push and hold the engine switch for more than 3 seconds.

While driving, the engine switch should only be operated in the event of an emergency.


If the engine stops while the vehicle is being driven, this could lead to an accident.


(a) If there is a malfunction in the stop light switch or STOP fuse, their signals may not be correctly transmitted to the power management control ECU. This may result in the engine not starting even if the engine switch is pressed while the brake pedal is depressed and the shift lever is in P or N.

To activate the starter:

(1) Turn the engine switch from off to on (ACC).

(2) Press and hold the engine switch for 15 seconds.
