NOTICE
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. D oing so may
cause the following serious damage to the vehicle:
● Engine stalling
● Short in electrical components
● Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle i s flooded, be
sure to have your Toyota dealer check the following:
● Brake function
● Changes in quantity and quality of oil and fluid used for the engine, trans-
mission, transfer (4WD models), differentials, etc.
● Lubricant condition for the propeller shaft, bearings and suspe nsion joints
(where possible), and the function of all joints, bearings, etc .

1884-1. Before driving
4RUNNER (U)■
Before towing
Check that the following conditions are met:
●Ensure that your vehicle’s tires are properly inflated. ( P. 472)
● Trailer tires are inflated according to the trailer manufacture r’s recommen-
dation.
● All trailer lights work as required by law.
● All lights work each time you connect them.
● The trailer ball is set at the proper height for the coupler on the trailer.
● The trailer is level when it is hitched.
Do not drive if the trailer is not level, and check for imprope r tongue weight,
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 ap propriate for tow-
ing purposes.
■ Break-in schedule
If your vehicle is new or equipped with any new power train com ponents
(such as an engine, transmission, differential or wheel bearing ), Toyota rec-
ommends that you do not tow a trailer until the vehicle has bee n driven for
over 500 miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can start
towing. However, for the next 500 miles (800 km), drive the veh icle at a speed
of less than 45 mph (72 km/h) when towing a trailer, and avoid full throttle
acceleration.
■ Maintenance
●If you tow a trailer, your vehicle will require more frequent m aintenance due
to the additional load. (See “Scheduled Maintenance Guide” or “ Owner’s
Manual Supplement”.)
● Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.
■ If trailer sway occurs
One or more factors (crosswinds, passing vehicles, rough roads, etc.) can
adversely affect handling of your vehicle and trailer, causing instability.
● If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering w heel.
• Begin releasing the accelerator pedal immediately but very gra dually to
reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle
and trailer should stabilize. (if enabled, Trailer Sway Control can also help to
stabilize the vehicle and trailer.)

H4F (high speed position)
Use this for normal driving on dry hard-surfaced roads. This position gives
greater economy, quietest ride and least wear.

Use this for driving only on tracks that permit the tires slide , like off-road,
icy or snow-covered roads.
L4L (low speed position, c enter differential locked)
Use this for maximum power and traction. Use “L4L” for climbing or
descending steep hills, off-road driving, and hard pulling in s and, mud or
deep snow.
