■Operational conditions
The pre-collision system is enabled and the system determines that the pos-
sibility of a frontal collision with a vehicle or pedestrian is high.
Each function is operational at the following speeds:
● Pre-collision warning:
• Vehicle speed is between approximately 7 and 110 mph (10 and 1 80
km/h). (For detecting a pedestrian, vehicle speed is between ap proxi-
mately 7 and 50 mph [10 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or ped estrian
ahead is approximately 7 mph (10 km/h) or more.
● Pre-collision brake assist:
• Vehicle speed is between approximately 20 and 110 mph (30 and 180
km/h). (For detecting a pedestrian, vehicle speed is between ap proxi-
mately 20 and 50 mph [30 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or ped estrian
ahead is approximately 20 mph (30 km/h) or more.
● Pre-collision braking:
• Vehicle speed is between approximately 7 and 110 mph (10 and 1 80
km/h). (For detecting a pedestrian, vehicle speed is between ap proxi-
mately 7 and 50 mph [10 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or ped estrian
ahead is approximately 7 mph (10 km/h) or more.
The system may not operate in the following situations:
● If a battery terminal has been disconnected and reconnected and then the
vehicle has not been driven for a certain amount of time
● If the shift lever is in R
● If VSC is disabled (only the pre-collision warning function wil l be opera-
tional)
● If the low speed four-wheel drive indicator is illuminated (onl y the pre-colli-
sion warning function will be operational)
■ Pedestrian detection function
The pre-collision system detects pedestri-
ans based on the size, profile, and motion
of a detected object. However, a pedes-
trian may not be detected depending on
the surrounding brightness and the
motion, posture, and angle of the
detected object, preventing the system
from operating properly. (P. 248)

tures. • Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspec t the condition of the battery.
● Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the rear tires.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
Winter driving tips
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a ma n-

3485-1. Using the air conditioning system and defogger
4RUNNER (U)
WARNING
■To prevent the windshield from fogging up
● Do not use during cool air operation in extremely humid weathe r.
The difference between the temperature of the outside air and that of the
windshield can cause the outer surface of the windshield to fog up, block-
ing your vision.
■ To prevent burns
● Do not touch the rear view mirror surfaces when the outside rear view mir-
ror defoggers are on.
● Do not touch the glass at lower part of the windshield or to the side of the
front pillars when the windshield wiper de-icer is on.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessa ry when the
engine is stopped.
■ When repairing/replacing parts of the air conditioning system
Have repair/replacement performed by your Toyota dealer.
When a part of the air conditioning system, such as the evapora tor, is to be
replaced, it must be replaced with a new one.
● Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers
from defogging.
