2144-2. Driving procedures
■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 (vehicles without a smart key system) or IGNITION ON mode
(vehicles with a smart key system) and the brake pedal is being depressed.
■ If the shift lever cannot be shift from P
First, check whether the brake pedal is being depressed.
If the shift lever cannot be shifted with your foot on the brak e pedal, there may
be a problem with the shift lock system. Have the vehicle inspected by your
Toyota dealer immediately.
The following steps may be used as an emergency measure to ensu re that
the shift lever can be shifted.
Releasing the shift lock:
Set the parking brake.
Vehicles without a smart key sys tem: Turn the engine switch to the
“LOCK” position.
Vehicles with a smart key syst em: Turn the engine switch off.
Depress the brake pedal.
Pry the cover up with a flathead
screwdriver or equivalent tool.
To prevent damage to the cover,
cover the tip of the screwdriver with
a rag.

Driving
Press the shift lock override
button.
The shift lever can be shifted while
the button is pressed.
■ If the “S” indicator does not come on even after shifting the shift lever to S
This may indicate a malfunction in the automatic transmission system. Have
the vehicle inspected by your Toyota dealer, immediately.
■ Downshifting restrictions warning buzzer (S mode)
To help ensure safety and driving performance, downshifting ope ration may
sometimes be restricted. In some circumstances, downshifting may not be
possible even when the shift lever is operated. (A buzzer will sound twice.)
■ Transmission protection function
If the tires spin continually when the vehicle becomes stuck in mud, dirt or
snow, or if the accelerator pedal is depressed and released repeatedly while
driving, the automatic transmission temperature may become too high and
the automatic transmission may be damaged.
To avoid damaging the automatic transmission, the system may temporarily
lock the gear.
If the automatic transmission temperature falls, the gear locking is canceled
and the automatic transmission is returned to the normal operation.

Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.

brake and depress the brake pedal.
If the accelerator pedal is accidentally depressed instead of t he brake pedal
when the shift lock override button is pressed and the shift lever is shifted
out of P, the vehicle may suddenly start, possibly leading to an accident
resulting in death or serious injury.

the daytime running lights turn on automatically when all of the following
conditions are met. (The daytime running lights are not designe d for use at
night.)

position
*: When the surroundings are bright
The daytime running lights remain on after they illuminate, even if the parking
brake is set again.

offers greater durability and consumes less electricity, so it can help improve
fuel economy.
