NOTICE
■When parking the vehicle
Always set the parking brake and shift the shift lever to P. Failure to do so
may cause the vehicle to move or the vehicle may accelerate sud denly if
the accelerator pedal is accidentally depressed.
■ Avoiding damage to vehicle parts
● Do not turn the steering wheel fully in either direction and ho ld it there for
an extended period of time.
Doing so may damage the power steering motor.
● When driving over bumps on the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
■ If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehi-
cle.
● It may be difficult to control your vehicle.
● The vehicle will make abnormal sounds or vibrations.
● The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( P. 608)
■ When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. D oing so may
cause the following serious damage to the vehicle:
● Engine stalling
● Short in electrical components
● Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle i s flooded, be
sure to have your Toyota dealer check the following:
● Brake function
● Changes in quantity and quality of oil and fluid used for the e ngine, tran-
saxle, transfer (AWD models), differential (AWD models), etc.
● Lubricant condition for the propeller shaft (AWD models), beari ngs and
suspension joints (where possible), and the function of all joints, bearings,
etc.

2324-2. Driving procedures
HIGHLANDER_U (OM0E031U)■
If the automatic transmission fl uid temperature warning message is dis-
played
When the warning message goes out, the vehicle can be driven ag ain.
If the warning message does not go out after waiting a while, h ave your vehi-
cle inspected by your Toyota dealer.
■ AI-SHIFT
The AI-SHIFT automatically selects the suitable gear according to driver per-
formance and driving conditions.
The AI-SHIFT automatically operates when the shift lever is in D. (Shifting the
shift lever to S cancels the function.) If the automatic transmission fluid tem-
perature warning message is displayed
while driving, make sure to return to D
position driving and reduce speed by eas-
ing off the accelerator pedal. Stop the
vehicle in a safe place, shift the shift lever
to P and let the engine idle until the warn-
ing message goes out.
WARNING
■ When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.
■ To prevent an accident when releasing the shift lock
Before pressing the shift lock override button, make sure to se t the parking
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 le ver is shifted
out of P, the vehicle may suddenly start, possibly leading to a n accident
resulting in death or serious injury.
