WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving the vehicle
● During normal driving, do not turn off the engine. Turning the engine off
while driving will not cause loss of steering or braking contro l, but the
power assist to these systems will be lost. This will make it m ore difficult to
steer and brake, so you should pull over and stop the vehicle a s soon as it
is safe to do so.
However, in the event of an emergency, such as if it becomes im possible
to stop the vehicle in the normal way: P. 463
● Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P. 233)
● Do not adjust the position of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
● Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle.
● AWD models: Do not drive the vehicle off-road.
This is not an AWD vehicle designed for off-road driving. Proce ed with all
due caution if it becomes unavoidable to drive off-road.
● AWD models: Do not drive across a river or through other bodies of water.
This may cause electric/electronic components to short circuit, damage
the engine or cause other serious damage to the vehicle.
● Do not drive in excess of the speed limit. Even if the legal sp eed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicl e has high-
speed capability tires. Driving over 85 mph (140 km/h) may resu lt in tire
failure, loss of control and possible injury. Be sure to consult a tire dealer
to determine whether the tires on your vehicle are high-speed c apability
tires or not before driving at such speeds.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When braking
● When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this ma y cause
one side of the vehicle to brake differently than the other sid e. Also the
parking brake may not securely hold the vehicle.
● If the power brake assist function does not operate, do not fol low other
vehicles closely and avoid hills or sharp turns that require br aking.
In this case, braking is still possible, but the brake pedal sh ould be
depressed more firmly than usual. Also, the braking distance wi ll increase.
Have your brakes fixed immediately.
● Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.
● The brake system consists of 2 individual hydraulic systems: If one of the
systems fails, the other will still operate. In this case, the brake pedal
should be depressed more firmly than usual and the braking dist ance will
increase. Have your brakes fixed immediately.
■ If the vehicle becomes stuck (AWD models)
Do not spin the wheels excessively when any of the tires is up in the air, or
the vehicle is stuck in sand or mud, etc. This may damage the d riveline
components or unexpectedly propel the vehicle forward or backwa rd, caus-
ing an accident.

NOTICE
■When driving the vehicle
● Do not depress the accelerator and brake pedals at the same tim e during
driving, as this may restrain the engine output.
● Do not use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.
■ When parking the vehicle
Always set the parking brake, and shift the shift lever to P. F ailure to do so
may cause the vehicle to move or the vehicle may accelerate sud denly if
the accelerator pedal is accidentally depressed.
■ Avoiding damage to vehicle parts
● Do not turn the steering wheel fully in either direction and ho ld it there for
an extended period of time.
Doing so may damage the power steering motor.
● When driving over bumps in the road, drive as slowly as possibl e to avoid
damaging the wheels, underside of the vehicle, etc.
■ If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehi-
cle.
● It may be difficult to control your vehicle.
● The vehicle will make abnormal sounds or vibrations.
● The vehicle will lean abnormally.
Information on what to do in case of a flat tire. ( P. 485, 499)
■ 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 e ngine, tran-
saxle, transfer (AWD models), rear differential (AWD models), e tc.
● Lubricant condition for the bearings and suspension joints (whe re possi-
ble) and the function of all joints, bearings, etc.

4-1. Before driving
●Reversing with a trailer attach ed is difficult and requires practice.
Grip the bottom of the steering wheel and move your hand to the
left to move the trailer to the left. Move your hand to the rig ht to
move the trailer to the right. (This is generally opposite to r eversing
without a trailer attached.) Avoid sharp or prolonged turning. Have
someone guide you when reversing to reduce the risk of an acci-
dent.
● As stopping distance is increased when towing a trailer, vehicl e-to-
vehicle distance should be increased. For each 10 mph (16 km/h)
of speed, allow at least one v ehicle and trailer length.
● Avoid sudden braking as you may skid, resulting in the trailer jack-
knifing and a loss of vehicle control. This is especially true on wet or
slippery surfaces.
● Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before maki ng
a 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 crosswinds, on wet or slippe ry
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. If in the S mode, transmission shift range position must be in 6 or
lower.
● 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.

Driving
●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
overheating, immediately turn off the air conditioning (if in use), pull
your vehicle off the road an d stop in a safe spot. (P. 509)
● Always place wheel blocks under both the vehicle’s and the trai ler’s
wheels when parking. Apply the parking brake firmly, and put th e
transmission in P. Avoid parking on a slope, but if unavoidable , do
so only after perform ing the following:
Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle’s and
trailer’s wheels.
When the wheel blocks are in pl ace, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.
Shift into P and turn off the engine.
● When restarting afte r parking on a slope:
With the transmission in P, start the engine. Be sure to keep t he
brake pedal pressed.
Shift into a forward gear. If reversing, shift into R.
Release the parking brake and brake pedal, and slowly pull or
back away from the wheel bloc ks. Stop and apply the brakes.
Have someone retrieve the blocks.

■Matching trailer ball height to trailer coupler height
■ Before towing
Check that the following conditions are met:
●Ensure that your vehicle’s tires are properly inflated. ( P. 522)
● 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 50 mph (80 km/h) when towing a trailer, and avoid full throttle
acceleration. No matter which class of tow hitch
applies, for a safe trailer hookup, the
trailer ball setup on must be proper height
for the coupler on the trailer.

■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.
● After the trailer swaying has stopped:
• Stop in a safe place. Get all occupants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer.
Make sure the load has not shifted.
Make sure the tongue weight is appropriate, if possible.
• Check the load in the vehicle. Make sure the vehicle is not overloaded after occupants get in.
If you cannot find any problems, the speed at which trailer swaying occurred
is beyond the limit of your particular vehicle-trailer combinat ion.
Drive at a lower speed to prevent instability. Remember that sw aying of the
towing vehicle-trailer increases as speed increases.
