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. 234)
● 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.

cle checked by your Toyota dealer immediately.

5688-2. Steps to take in an emergency
HIGHLANDER_U (OM48E98U)■
When a tire is replaced with a spare tire
Vehicles with a compact spare tire
The compact spare tire is not equipped with a tire pressure warning valve
and transmitter. If a tire goes flat, the tire pressure warning light will not
turn off even though the flat tire has been replaced with the spare tire.
Replace the spare tire with the repaired tire and adjust the tire inflation
pressure. The tire pressu re warning light will go off after a few minutes.
Vehicles with a full-size spare tire
The spare tire is also equipped with the tire pressure warning valve and
transmitter. The tire pressure warning light will turn on if the tire inflation
pressure of the spare tire is low. If a tire goes flat, even though the flat tire
is replaced with the spare tire, the tire pressure warning light does not
turn off. Replace the spare tire with the repaired tire and adjust to the
proper tire inflation pressure. The tire pressure warning light will turn off
after a few minutes.
■Conditions that the tire pressure warning system may not function
properly
 P. 5 2 0
■If the tire pressure warning light frequently comes on after blinking

Toyota dealer.

belt reminder buzzer be operational to alert the driver and front passenger
when seat belts are not fastened.
