1063-1. Key information
4RUNNER (U)■
Key battery depletion
Vehicles with a smart key system
● The standard battery life is 1 to 2 years.
● If the battery becomes low, an alarm will sound in the cabin wh en the engine
stops.
● As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indi-
cate that the electronic key battery may be depleted. Replace the battery
when necessary. ( P. 443)
• The smart key system or the wireless remote control does not o perate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
● To avoid serious deterioration, do not leave the electronic key within 3 ft. (1
m) of the following electrical appliances that produce a magnet ic 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 b attery may be
depleted. Replace the battery when necessary. ( P. 443)
■ Precautions when disconnecting the battery (vehicles with a sma rt 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 reconnectin g 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 ba ttery is
reconnected, the system will return to the mode it was in befor e the battery
was disconnected. Before disconnecting the battery, turn the en gine switch
off.
If you are unsure what mode the engine switch was in when the b attery was
disconnected, be especially careful when reconnecting the batte ry.

Operation of each component
4RUNNER (U)
■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, th e board will
extend.
If an obstacle is detected 3 times in a row during Automatic ru nning 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 on e 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 t he 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 spe ed 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 nothing is caught between
the board and the vehicle.
Additionally, if the engine is started immediately after a door has been closed,
the automatic running board may not retract completely and the automatic
running boards indicator may illuminate. In this case, open and close the door
to retract the running board and turn off the indicator.
■ If the Automatic running boards indicator light flashes
There may be a malfunction in the Automatic running boards syst em. Have
the vehicle inspected by your Toyota dealer immediately.
■ When snow or mud is attached to the board or the board is froze n
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 sw itch 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 tim e they are oper-
ated. However, from the second time onwards, the boards will re sume normal
operation.
■ When getting in and out of the vehicle
Take care because clothes and shoes may become dirty due to con tact with
the lower part of the vehicle body.

2024-1. Before driving
4RUNNER (U)
●Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before maki ng
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 mak ing
a wider than normal turning radius.
● Slow down before making a turn, in cross winds, on wet or slipp ery
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 lengt h of
your trailer, and be sure you have plenty of room before changi ng
lanes.
● To maintain engine braking efficiency and charging system perfo r-
mance when using engine braking, do not put the transmission in
D.
● Instability happens more frequently when descending steep or lo ng
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 bra kes
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 drivin g
up a long or steep grade. If the engine coolant temperature gau ge
indicates overheating, immediately turn off the air conditionin g (if in
use), pull your vehicle off the road and stop in a safe spot.
