Make sure that the parking brake is set and shift the shift lever to D.
Gently depress the accelerator pedal.
Release the parking brake.
■When starting off on an uphill
The hill-start assist control will activate. ( →P. 331)
■ Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the win-
dows may become fogged-up, and the road will be slippery.
● Drive carefully when it starts to rain, because the road surface will be espe-
cially slippery.
● Refrain from high speeds when driving on an expressway in the rain,
because there may be a layer of water between the tires and the road sur-
face, preventing the steering and brakes from operating properly.
■ Engine speed while driving
In the following conditions, the engine speed may become high while driving.
This is due to automatic up-shifting control or down-shifting implementation to
meet driving conditions. It does not indicate sudden acceleration.
●The vehicle is judged to be driving uphill or downhill
● When the accelerator pedal is released

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving the vehicle
● 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. 227)
● Do not adjust the positions 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.
● Do not drive in excess of the speed limit. Even if the legal speed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicle has h\
igh-
speed capability tires. Driving over 85 mph (140 km/h) may result 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 capability
tires or not before driving at such speeds.
■ When driving on slippery road surfaces
● Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle.
● Sudden acceleration, engine braking due to shifting, or changes in engine
speed could cause the vehicle to skid.
● After driving through a puddle, lightly depress the brake pedal to make
sure that the brakes are functioning properly. Wet brake pads may prevent
the brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected.

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 may cause
one side of the vehicle to brake differently than the other side. Also, the
parking brake may not securely hold the vehicle.
● If the power brake assist function does not operate, do not follow other\
vehicles closely and avoid hills or sharp turns that require braking.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will 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 distance 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, mud, etc. This may damage the driveline com-
ponents or propel the vehicle forward or backward, causing an accident.
NOTICE
■When driving the vehicle
● Do not depress the accelerator and brake pedals at the same time during
driving, as this may restrain driving torque.
● Do not use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.

Contact your Toyota dealer for further information about additional
requirements such as a towing kit, etc.
Trailer towing
Your vehicle is designed primarily as a passenger-and-load-car-
rying vehicle. Towing a trailer can have an adverse impact on
handling, performance, braking, durability, and fuel consump-
tion. For your safety and the safe ty of others, you must not over-
load your vehicle or trailer. You must also ensure that you are
using appropriate towing equipmen t, that the towing equipment
has been installed correctly an d used properly, and that you
employ the requisite driving habits.
Vehicle-trailer stability and braking performance are affected by
trailer stability, brake performance and setting, trailer brakes,
the hitch and hitch systems (if equipped).
To tow a trailer safely, use extreme care and drive the vehicle in
accordance with your trailer’s characteristics and operating
conditions.
Toyota warranties do not appl y to damage or malfunction
caused by towing a trailer for commercial purposes.

GAWR (Gross Axle
Weight Rating)
The maximum allowable gross
axle weight. The gross axle
weight is the load placed on
each axle (front and rear).
■TWR (Trailer Weight Rating)
The maximum allowable gross
trailer weight. The gross trailer
weight is the sum of the trailer
weight and the weight of the
cargo in the trailer.
TWR is calculated assuming
base vehicle with one driver,
one front passenger, towing
package (if available), hitch and
hitch systems (if required).
Additional optional equipment, passengers and cargo in the vehicle will
reduce the trailer weight rating so as not to exceed GCWR, GVWR and
GAWR.
If the gross trailer weight exceeds 3000 lb. (1360 kg), it is recommended
to use a trailer with 2 or more axles.

●As stopping distance is increased when towing a trailer, vehicle-to
vehicle distance should be increased. For each 10 mph (16 km/h)
of speed, allow at least one vehicle 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 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 c an destabilize the trailer.
● Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehi cle, do not forget the length of
your trailer, and be sure you hav e plenty of room before changing
lanes.
● To maintain engine braking efficiency and charging system perfor-
mance when using engine braking, do not put the transmission in
D. If in the S mode, the transmis sion shift range position must be in
6 (8-speed models) or 4 (6-speed models) or lower.
● 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 the brakes to overheat and result in
reduced braking efficiency.

2124-1. Before 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 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.
( → P. 644)
● Always place wheel blocks under both the vehicle’s and the trailer’s
wheels when parking. Apply the parking brake firmly, and put the
transmission in P. Avoid parking on a slope, but if unavoidable, do
so only after performing 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 after parking on a slope:
With the transmission in P, start the engine. Be sure to keep the
brake pedal depressed.
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.

Break-in schedule
If your vehicle is new or equipped with any new power train components
(such as an engine, transmission, differential or wheel bearing), Toyota rec-
ommends that you do not tow a trailer until the vehicle has been 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 vehicle at a speed
of less than 50 mph (80 km/h) when towing a trailer, and avoid full throttle
acceleration.
■ Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance 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 wheel.
• Begin releasing the accelerator pedal immediately but very gradually 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.)
● 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 combination. Drive at a
lower speed to prevent instability. Remember that swaying of the towing vehi-
cle-trailer increases as speed increases.
