Toyota Corolla Cross: Operation Check

OPERATION CHECK

CHECK NAVIGATION SYSTEM NORMAL CONDITION (w/ Navigation Function)

(a) If the cause of a symptom is any of the following, the corresponding symptom is normal; it is not due to a malfunction.

Symptom

Answer

A longer route than expected is chosen.

Depending on the road conditions, the radio and display receiver assembly may determine that a longer route is quicker.

Even when distance priority is high, the shortest route is not shown.

Some routes may not be advised due to safety concerns.

When the vehicle is put into motion immediately after the hybrid system starts, the navigation system deviates from the correct position.*1

If the vehicle starts before the navigation system activates, the system may not react.

When the vehicle is put into motion immediately after the engine starts, the navigation system deviates from the correct position.*2

When driving on certain types of roads, especially new roads, the vehicle position deviates from the correct position.

When the vehicle is driving on new roads not available on the internal memory, the system attempts to match it to another nearby road, causing the position mark to deviate.

Route guidance uses roads with congestion

If the congestion is short, congested road avoidance will not be performed.

Some specific areas of the map are not displayed

Urban map areas without data will not be displayed.

  • *1: for HEV Model
  • *2: for Gasoline Model

(b) The following symptoms are not malfunctions, but may occur due to margin of error in the GNSS, gyro sensor, speed sensor or navigation system.

(1) The current position mark may be displayed on a nearby parallel road.

(2) Immediately after a fork in the road, the current vehicle position mark may be displayed on the wrong road.

(3) When the vehicle turns right or left at an intersection, the current vehicle position mark may be displayed on a nearby parallel road.

(4) When the vehicle is carried, such as on a ferry, and the vehicle itself is not driving, the current vehicle position mark may be displayed in the position where the vehicle was until a measurement can be performed by the GNSS.

(5) When the vehicle travels on a steep hill, the current vehicle position mark may deviate from the correct position.

(6) When the vehicle makes a continuous turn (e.g. 360, 720, 1080 degrees), the current vehicle position mark may deviate from the correct position.

(7) When the vehicle moves erratically, such as constant lane changes, the current vehicle position mark may deviate from the correct position.

(8) When the ignition switch is turned to ACC or ON and the vehicle is turned on a turntable before parking, the current vehicle position mark may not indicate the correct direction. The same will occur when the vehicle comes out of the parking garage.

(9) When the vehicle travels on a snowy road or a mountain path with tire chains installed or using a spare tire, the current vehicle position mark may deviate from the correct position.

(10) When the tires are changed, the current vehicle position mark may deviate from the correct position.

HINT:

  • A change in tire diameter may cause a speed sensor error.
  • Performing "tire change" in calibration mode will allow the system to correct the current vehicle position faster.
