the vehicle inspected by your Toyota dealer.
*2: If equipped
*3: Refer to “Navigation and Multimedia System Owner’s Manual”.
*4: The light comes on when the system is turned off. The light flashes fasterthan usual to indicate that the system is operating.

illuminate in the following situations:
• When the power switch is turned to ON mode while the BSM main switch is set to ON.
• When the BSM main switch is set to ON while the power switch is in ON mode.
If the system is functioning correctly, the BSM outside rear view mirror indi-
cators will turn off after a few seconds.

WARNING
■ If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning lights not
come on when you start the engine, this could mean that these systems are
not available to help protect you in an accident, which could result in death
or serious injury. Have the vehicle inspected by your Toyota dealer immedi-
ately if this occurs.

Driving
HIGHLANDER_HV_U (OM48F02U)
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving the vehicle
● Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P. 237)
● Do not adjust the positions of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
● Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle.
● Do not drive in excess of the speed limit. Even if the legal speed limit per-
mits it, do not drive over 85 mph ( 140 km/h) unless your vehicle has high-
speed capability tires. Driving over 85 mph (140 km/h) may result in tire
failure, loss of control and possible injury. Be sure to consult a tire dealer
to determine whether the tires on y our vehicle are high-speed capability
tires or not before driving at such speeds.
■ When driving on slippery road surfaces
● Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle.
● Sudden acceleration, engine braking due to shifting, or changes in engine
speed could cause the vehicle to skid.
● After driving through a puddle, lightly depress the brake pedal to make
sure that the brakes are functioning properly. Wet brake pads may prevent
the brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected.
