1944-1. Before driving
HIGHLANDER_U (OM0E031U)
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.

3464-6. Driving tips
HIGHLANDER_U (OM0E031U)
NOTICE
■To prevent water damage
Take all necessary safety measures to ensure that water damage to the
engine or other components does not occur.
● Water entering the engine air intake will cause severe engine d amage.
● Water entering the automatic transmission will cause deteriorat ion in shift
quality, locking up of your transmission accompanied by vibrati on, and ulti-
mately damage.
● Water can wash the grease from wheel bearings, causing rusting and pre-
mature failure, and may also enter the differentials, transmission and
transfer case, reducing the gear oil’s lubricating qualities.
■ When you drive through water
If driving through water, such as when crossing shallow streams , first check
the depth of the water and the bottom of the riverbed for firmn ess. Drive
slowly and avoid deep water.
■ Inspection after off-road driving
● Sand and mud that has accumulated in brake drums and around bra ke
discs may affect braking efficiency and may damage brake system compo-
nents.
● Always perform a maintenance inspection after each day of off-r oad driv-
ing that has taken you through rough terrain, sand, mud, or wat er. For
scheduled maintenance information, refer to the “Scheduled Main tenance
Guide” or “Owner’s Manual Supplement”.
