■Downshift restriction
The maximum allowable speeds are as follows.
■ AI-SHIFT
AI-SHIFT automatically selects the suitable gear according to driver perfor-
mance and driving conditions.
AI-SHIFT automatically operates when the shift lever is in the D position.
■ When driving with cruise cont rol activated (if equipped)
Even when performing the following actions with the intent of enabling engine
braking, engine braking will not activate while downshifting to 3 because
cruise control will not be canceled. ( →P. 190)
■ Shift lock system
The shift lock system is a system to prevent accidental operation of the shift
lever in starting.
The shift lever can be shifted from P only when the engine switch is in the
“ON” position and the brake pedal is being depressed.
■ If the shift lever canno t be shifted from P
First, check whether the brake pedal is being depressed.
If the shift lever cannot be shifted with your foot on the brake pedal, there may
be a problem with the shift lock system. Have the vehicle inspected by y\
our
Toyota dealer immediately.
The following steps may be used as an emergency measure to ensure that
the shift lever can be shifted.
Releasing the shift lock:
Set the parking brake.
Turn the engine switch to the “LOCK” position.
Depress the brake pedal.
Pry the cover up with a flathead
screwdriver or equivalent tool.
To prevent damage to the cover,
wrap the tip of the screwdriver with
a rag.

brake and depress the brake pedal.
If the accelerator pedal is accidentally depressed instead of the brake pedal

out of P, the vehicle may suddenly start leading to an accident which may
result in death or serious injury.

than the headlights.) Daytime running lights are not designed for use at
night.
For type C of this headlight, daytime running lights can be turned off by
operating the switch.
Vehicles with projector type headlights: To make your vehicle more visible
to other drivers during daytime driving, the daytime running lights turn on
