943-1. Key information
4RUNNER (U)_(OM35B18U)●
To avoid serious deterioration, do not leave the electronic key within 3 ft. (1
m) of the following electrical appl iances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Table lamps
• Induction cookers
Vehicles without a smart key system
If the wireless remote control function does not operate, the battery may be
depleted. Replace the battery when necessary. ( P. 377)
■ Precautions when disconnecting the battery (vehicles with a smart key
system)
● In some cases, it may not be possible to unlock the doors using the smart
key system immediately after the battery has been disconnected. Use the
wireless remote control or the mechanical key to lock or unlock the doors.
● The engine may not start on the first attempt after reconnecting the battery
but will start normally after the second attempt. This is not a malfunction.
● The engine switch mode is memorized by the vehicle. When the battery is
reconnected, the system will return to the mode it was in before the battery
was disconnected. Before disconnecting the battery, turn the engine switch
off.
If you are unsure what mode the engine switch was in when the battery was
disconnected, be especially careful when reconnecting the battery.
■ Replacing the battery
P. 377
■ Confirmation of the registered key number
The number of keys already registered to the vehicle can be confirmed. Ask
your Toyota dealer for details.
■ If a wrong key is used (vehicles with a smart key system)
The key cylinder rotates freely to isolate inside mechanism.
■ Certification for wireless remote control

1123-2. Opening, closing and locking the doors
4RUNNER (U)_(OM35B18U)
■Jam protection function
During Automatic running boards operation:
If a board contacts an obstacle when extending, it will retract. If an obstacle
gets caught between a board and the vehicle when retracting, the board will
extend.
If an obstacle is detected 3 times in a row during Automatic running boards
operation, the board will stop at the position it contacts the obstacle. When a
side door on the same side as the board is opened and closed one more
time, the board will extend and retract, or retract and extend. After this, the
board will resume normal operation.
■ Automatic retraction function
The boards will be automatically retracted, for safety, under the following con-
ditions:
●A board is not completely retracted
● Vehicle speed is approximately 5 mph (8 km/h) or higher
The boards will not automatically extend again when vehicle speed returns to
less than 5 mph (8 km/h).
■ If the Automatic running boards indicator comes on when driving first
commences
A board has not completely retracted. Check that no obstacles are caught
between a board and the vehicle.
■ If the Automatic running boards indicator light flashes
There may be a malfunction in the Automatic running boards system. Have
the vehicle inspected by your Toyota dealer immediately.
■ When snow or mud is attached to the board or the board is frozen
The Automatic running boards may not operate correctly. Before stepping on
a board, check that it is completely extended. If the Automatic running boards
are not operating correctly, turn the Automatic running boards switch off and
refrain from use.
When removing snow or mud, turn the Automatic running boards switch off.
■ After recharging/reconnecting the battery
If the Automatic running boards have not completely extended or retracted,
the boards may not move in the intended direction the first time they are oper-
ated. However, from the second time onwards, the boards will resume normal
operation.
■ When getting in and out of the vehicle
Take care because clothes and shoes may become dirty due to contact with
the lower part of the vehicle body.

1844-1. Before driving
4RUNNER (U)_(OM35B18U)
●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 can destabilize the trailer.
● Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehicle, do not forget the length of
your trailer, and be sure you hav e plenty of room before changing
lanes.
● To maintain engine braking effici ency 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 th e 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.
