1864-1. Before driving
4RUNNER (U)_(OM35B46U)
●Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before making
turn.
● Note that when making a turn, the trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by making
a wider than normal turning radius.
● Slow down before making a turn, in cross winds, on wet or slippery
surfaces, etc.
Increasing vehicle speed c an destabilize the trailer.
● Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehi cle, do not forget the length of
your trailer, and be sure you hav e plenty of room before changing
lanes.
● To maintain engine braking efficiency and charging system perfor-
mance when using engine braking, do not put the transmission in
D.
● Instability happens more frequently when descending steep or long
downhill grades. Before descending, slow down and downshift. Do
not make sudden downshifts while descending steep or long down-
hill grades.
● Avoid holding the brake pedal down too long or applying the brakes
too frequently. This could cause the brakes to overheat and result in
reduced braking efficiency.
● Due to the added load of the trailer, your vehicle’s engine may over-
heat on hot days (at temperatures over 85°F [30°C]) when driving
up a long or steep grade. If t he engine coolant temperature gauge
indicates overheating, immediately turn off the air conditioning (if in
use), pull your vehicle off the road and stop in a safe spot.

The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection
distance may shorten, or detection may be impossible.
• Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at slow speeds, there is a possibility that the obstacle will come within the
sensor’s detection areas before the display is shown and the warning
beep sounds.
• Thin posts or objects lower than the sensor may not be detected for colli- sion when approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of audio system or air flow noise of air conditioning system.
■ If a message is displayed on the multi-information display
