→P. 107
■Conditions affecting operation
→P. 127
■Notes for the entry function
→P. 128
■If the engine does not start
●The engine immobilizer system may not have been deactivated. (→P. 67)
Contact your Toyota dealer.
●Vehicles with a continuously variable transmission: Check that the shift lever
is securely set in P. The engine may not start if the shift lever is displaced
out of P.
“Shift to P position to Start” will be displayed on the multi-information dis-
play.
■Steering lock
After turning the engine switch off and opening and closing the doors, the
steering wheel will be locked due to the steering lock function. Operating the
engine switch again automatically cancels the steering lock.
■When the steering lock cannot be released
Vehicles with a manual transmission: Press the engine switch while turning
the steering wheel left and right.
■Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, the motor may be sus-
pended if the engine is turned on and off repeatedly in a short period of time.
In this case, refrain from operating the engine. After about 10 seconds, the
steering lock motor will resume functioning. “Steering Lock Active” will be displayed on
the multi-information display.
Vehicles with a continuously variable
transmission: Check that the shift lever is
set in P. Press the engine switch while
turning the steering wheel left and right.

Driving
COROLLA_TMMMS_TMMC_U (OM02494U)■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur, refrain
from excessive steering input or stop the vehicle and turn the engine off. The
EPS system should return to normal within 10 minutes.
■Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assist control will
operate:
●When starting off forward/backward
Vehicles with a manual transmission
• The shift lever is in a position other than R (when starting off forward on
an upward incline).
• The shift lever is in R (when starting off backward on an upward incline).
Vehicles with a continuously variable transmission
The shift lever is in a position other than P or N (when starting off forward/
backward on an upward incline).
●The vehicle is stopped.
●The accelerator pedal is not depressed.
●The parking brake is not engaged.
■Automatic system cancelation of hill-start assist control
The hill-start assist control will turn off in any of the following situations:
●When starting off forward/backward
Vehicles with a manual transmission
• The shift lever is in R (when starting off forward on an upward incline).
• The shift lever is in a position other than R (when starting off backward
on an upward incline).
Vehicles with a continuously variable transmission
