4RUNNER_U
■When the rear window wiper and washer switch is turned off
The rear wiper will stop operation, and return to the retracted position after
approximately 3 seconds.
However, if the engine switch is turned to the “ACC” or “LOCK” position
(vehicles without a smart key system) or the “ENGINE START STOP” switch
is turned to ACCESSORY mode or tur ned off (vehicles with a smart key sys-
tem) while the rear wiper is operating, the rear wiper will stop at that position
and will not return to the retracted position.
■ If no washer fluid sprays
Check that the washer nozzle is not blocked if there is washer fluid in the
washer fluid reservoir.
■ Customization that can be co nfigured at Toyota dealer
Settings (e.g. drip prevention function) can be changed.
(Customizable features P. 638)
NOTICE
■When the rear window is dry
Do not use the wiper, as it may damage the rear window.
■ When the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may over-
heat.
■ When a nozzle becomes blocked
Do not try to clear it with a pin or other object. The nozzle will be damaged.

NOTICE
■To prevent water damage
Take all necessary safety measures to ensure that water damage to the
engine or other components does not occur.
● Water entering the engine air intake will cause severe engine damage.
● Water entering the automatic transmission will cause deterioration in shift
quality, locking up of your transmission accompanied by vibration, and ulti-
mately damage.
● Water can wash the grease from wheel bearings, causing rusting and pre-
mature failure, and may also enter the differentials, transmission and
transfer case, reducing the gear oil’s lubricating qualities.
■ When you drive through water
If driving through water, such as when crossing shallow streams, first check
the depth of the water and the bottom of the riverbed for firmness. Drive
slowly and avoid deep water.
■ Inspection after off-road driving
● Sand and mud that has accumulate d in brake drums and around brake
discs may affect braking efficiency and may damage brake system compo-
nents.
● Always perform a maintenance inspection after each day of off-road driv-
ing that has taken you through rough terrain, sand, mud, or water. For
scheduled maintenance information, refer to the “Scheduled Maintenance
Guide” or “Owner’s Manual Supplement”.

●
Note that when making a turn, th e trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by making
a larger than normal turning radius.
● Crosswinds and rough roads will adversely affect handling of your
vehicle and trailer, causing sway . Periodically check the rear to
prepare for being passed by large trucks or buses, which may
cause your vehicle and trailer to sway. If swaying occurs, firmly grip
the steering wheel, reduce speed immediately but gradually, and
steer straight ahead. Never increase speed. If you make no
extreme correction with the stee ring or brakes, your vehicle and
trailer will stabilize.
● 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.
● In order to maintain engine braking efficiency when driving on a
long steep downgrade, do not use overdrive. Transmission shift
range position must be in 3 (standard type), or “4”, in the S mode
(multi-mode type).
● Due to the added load of the trailer, your vehicle’s engine may
overheat on hot days (at temperatur es over 85°F [30°C] when driv-
ing up a long or steep grade. If the engine coolant temperature
gauge indicates overheating, immedi ately turn off the air condition-
ing (if in use), pull your vehicle off the road and stop in a safe spot.

Service connector for towing brake controller
■ Before towing
Check that the following conditions are met:
● The vehicle’s tires are properly inflated.
● Trailer tires are inflated according to the trailer manufacturer’s recom-
mendation.
● All trailer lights work.
● All lights work each time you connect them.
● The trailer ball is set up at the proper height for the coupler on the t\
railer.
● The vehicle remains level when a loaded or unloaded trailer is hitched.
Do not drive if the vehicle is not level, and check for improper tongue
load, overloading, worn suspension, or other possible causes.
● The trailer cargo is securely loaded.
● The rear view mirrors conform to all applicable federal, state/provincial or
local regulations. If they do not, install rear view mirrors appropriate for
towing purposes.
■ Break-in schedule
If your vehicle is new or equipped with any new power train components
(such as an engine, transmission, differential and wheel bearing), Toyota
recommends that you do not tow a trailer until it has been driven for over 500
miles (800 km).
However, avoid full throttle acceleration.
Your vehicle is equipped with a service
connector for the trailer brake controller
as shown.

■ Display
In the following situations, the correct outside temperature may not be dis-
played, or the display may take longer than normal to change:
● When the vehicle is stopped, or moving at low speeds (less than 14 mph
[24 km/h])
● When the outside temperature has changed suddenly (at the entrance/
exit of a garage, tunnel, etc.)
If the outside temperature lowers to 37 °F
(3 °C) or below when the engine switch is
in the “ON” position (vehicles without a
smart key system) or the “ENGINE
START STOP” switch is in IGNITION ON
mode (vehicles with a smart key system),
the “ICE” indicator will come on to warn
the driver that roads may be icy. Check
the road surface and drive carefully. (The
indicator will go off when the outside tem-
perature rises to 41 °F [5 °C].)
If the outside temperature lowers to 37 °F
(3 °C) or below when the engine switch is
