Driving
■Break-in schedule
Toyota recommends that vehicles fitted with new power train components should not be used for towing trailers for
the first 800 km (500 miles).
■Safety checks before towing
●Check that the maximum load limit for
the towing hitch/bracket hitch ball is not exceeded. Bear in mind that the coupling weight of the trailer will add
to the load exerted on the vehicle. Also make sure that you will not be towing a load that exceeds the maxi-
mum permissible axle capacity.
●Ensure that the trailer load is secure.
●Supplementary outside rear view mir- rors should be added to the vehicle if
the traffic behind cannot be clearly seen with standard mirrors. Adjust the extending arms of these mirrors on
both sides of the vehicle so that they always provide maximum visibility of the road behind.
■Maintenance
●Maintenance must be performed more frequently when using the vehicle for
towing due to the greater weight bur- den placed on the vehicle compared to normal driving.
●Retighten all bolts securing the hitch-ing ball and bracket after towing for
approximately 1000 km (600 miles).
■If trailer sway occurs
One or more factors (crosswinds, pass- ing 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 appro-priate, if possible.
• Check the load in the vehicle. Make sure the vehicle is not over-loaded 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
vehicle-trailer increases as speed
increases.
Your vehicle will handle differently
when towing a trailer. In order to
avoid accident, death or serious
injury, keep the following in mind
NOTICE
■When the rear bumper strength- ening material is aluminum
Ensure the steel bracket part does not
come directly in contact with that area.When steel and aluminum come into
contact, there is a reaction similar to corrosion, which will weaken the sec-tion concerned and may result in
damage. Apply a rust inhibitor to parts that will come in contact when attach-ing a steel bracket.

4-1. Before driving
when towing:
■Checking connections
between trailer and lights
Stop the vehicle and check the
operation of the connection
between the trailer and lights after
driving for a brief period as well as
before starting off.
■Practicing driving with a cou-
pled trailer
zGet the feel for turning, stopping
and reversing with the trailer
coupled by practicing in an area
with no or light traffic.
zWhen reversing with a coupled
trailer, hold the section of the
steering wheel nearest to you
and rotate clockwise to turn the
trailer left or counterclockwise to
turn it right. Always rotate a little
at a time to prevent steering
error. Have someone guide you
when reversing to lessen the risk
of an accident.
■Increasing vehicle-to-vehicle
distance
At a speed of 10 km/h (6 mph), the
distance to the vehicle running
ahead of you should be equivalent
to or greater than the combined
length of your vehicle and trailer.
Avoid sudden braking that may
cause skidding. Otherwise, the
vehicle may spin out of control. This
is especially true when driving on
wet or slippery road surfaces.
■Sudden acceleration/steering
input/cornering
Executing sharp turns when towing
may result in the trailer colliding
with your vehicle. Decelerate well in
advance when approaching turns
and take them slowly and carefully
to avoid sudden braking.
■Important points regarding
turning
The wheels of the trailer will travel
closer to the inside of the curve
than the wheels of the vehicle. To
make allowance for this, take the
turns wider than you would nor-
mally do.
■Important points regarding
stability
Vehicle movement resulting from
uneven road surfaces and strong
crosswinds will affect handling. The
vehicle may also be rocked by
passing buses or large trucks. Fre-
quently check behind when moving
alongside such vehicles. As soon
as such vehicle movement occurs,
immediately start to decelerate
smoothly by slowly applying the
brakes. Always steer the vehicle
straight ahead while braking.
■Passing other vehicles
Consider the total combined length
of your vehicle and trailer and
ensure that the vehicle-to-vehicle
distance is sufficient before execut-
ing lane changes.

4-1. Before driving
Driving
■Transmission information
Multidrive
To maintain engine braking effi-
ciency and charging system perfor-
mance when using engine braking,
do not use the transmission in D,
must be in M and select gear step 4
or lower. ( →P.164)
Manual transmission
Refrain from driving in 6th gear to
maintain the effectiveness of
engine braking and to maintain
charging system performance.
■If the engine overheats
Towing a loaded trailer up a long,
steep incline in temperatures
exceeding 30°C (85°F) may result
in the engine overheating. If the
engine coolant temperature gauge
indicates that the engine is over-
heating, turn the air conditioning off
immediately, leave the road and
stop the vehicle in a safe place.
( →P.405)
■When parking the vehicle
Always place wheel chocks under
the wheels of both the vehicle and
trailer. Firmly set the parking brake
and shift the shift lever to P (Multid-
rive) and 1 or R (manual transmis-
sion).
WARNING
Follow all the instructions described in
this section. Failure to do so could cause an accident resulting in death or serious injury.
■Trailer towing precautions
When towing, make sure that none of the weight limits are exceeded.
( →P.153)
■Vehicle speed in towing
Observe the legal maximum speeds for trailer towing.
■Before descending hills or long declines
Reduce speed and downshift. How-
ever, never downshift suddenly while descending steep or long downhill grades.
■Operation of the brake pedal
Do not hold the brake pedal
depressed often or for long periods of time. Doing so may result in the brake overheating or reduce braking effects.
■To avoid accident or injury
●Vehicles with a compact spare tire:
Do not tow a trailer when the com- pact spare tire is installed on your vehicle.
●Vehicles with the emergency tire puncture repair kit: Do not tow a
trailer when the tire installed is repaired with the emergency tire puncture repair kit.
●Vehicles with a Dynamic radar cruise control: Do not use dynamic
radar cruise control when you are towing.
NOTICE
■Do not directly splice trailer
lights
Directly splicing trailer lights may damage your vehicle’s electrical sys-
tem and cause a malfunction.

WARNING
●Do not attempt to test the operation of the pre-collision system yourself.
Depending on the objects used for testing (dummies, cardboard objects imitating detectable objects,
etc.), the system may not operate properly, possibly leading to an accident.
■Pre-collision braking
●When the pre-collision braking
function is operating, a large amount of braking force will be applied.
●If the vehicle is stopped by the operation of the pre-collision brak-
ing function, the pre-collision brak- ing function operation will be canceled after approximately 2 sec-
onds. Depress the brake pedal as necessary.
●The pre-collision braking function may not operate if certain opera-tions are performed by the driver. If
the accelerator pedal is being depressed strongly or the steering wheel is being turned, the system
may determine that the driver is tak- ing evasive action and possibly pre-vent the pre-collision braking
function from operating.
●In some situations, while the pre-
collision braking function is operat- ing, operation of the function may be canceled if the accelerator pedal
is depressed strongly or the steer- ing wheel is turned and the system determines that the driver is taking
evasive action.
●If the brake pedal is being
depressed, the system may deter- mine that the driver is taking eva-sive action and possibly delay the
operation timing of the pre-collision braking function.
■Emergency steering assist
●As emergency steering assist oper-ation will be canceled when the sys-
tem determines that lane departure prevention function has been com-pleted.
●Emergency steering assist may not operate or may be cancel in the fol-
lowing cases as the system may determine the driver is taking actions.
• If the accelerator pedal is being depressed strongly, the steering
wheel is being operated sharply, the brake pedal is being depressed or the driver is giving turn signal. In
this case the system may deter- mine that the driver is taking eva-sive action and the emergency
steering assist may not operate.
• In some situations, while the emer-
gency steering assist is operating, operation of the function may be canceled if the accelerator pedal is
depressed strongly, the steering wheel is operated sharply or the brake pedal is being depressed and
the system determines that the driver is taking evasive action.
• When the emergency steering assist is operating, if the steering wheel is held firmly or is operated in
the opposite direction to that which the system is generating torque, the function may be canceled.
■When to disable the pre-colli-sion system
In the following situations, disable the system, as it may not operate prop-erly, possibly leading to an accident
resulting in death or serious injury:
●When the vehicle is being towed
●When your vehicle is towing another vehicle

reflects radio waves, such as a large truck or guardrail• When driving near a TV tower, broad-
casting station, electric power plant, radar equipped vehicles, etc., or other location where strong radio waves or
electrical noise may be present • When there are many things which can reflect the radio waves of the
radar in the vicinity (tunnels, truss bridges, gravel roads, snow covered road that have tracks, etc.)
• While making a right/left turn, when an oncoming vehicle or a crossing pedestrian has already exited the path
of your vehicle • While making a right/left turn, closely in front of an oncoming vehicle or a
crossing pedestrian. • While making a right/left turn, when an oncoming vehicle or a crossing
pedestrian stops before entering the path of your vehicle• While making a right/left turn, when an
oncoming vehicle turns right/left in front of your vehicle
• While steering into the direction of oncoming traffic

WARNING
■Before using LTA system
●Do not rely solely upon the LTA sys-
tem. The LTA system does not automatically drive the vehicle or reduce the amount of attention that
must be paid to the area in front of the vehicle. The driver must always assume full responsibility for driving
safely by paying careful attention to the surrounding conditions and operating the steering wheel to cor-
rect the path of the vehicle. Also, the driver must take adequate breaks when fatigued, such as from
driving for a long period of time.
●Failure to perform appropriate driv-
ing operations and pay careful attention may lead to an accident, resulting in death or serious injury.
●When not using the LTA system, use the LTA switch to turn the sys-
tem off.
■Situations unsuitable for LTA
system
In the following situations, use the LTA switch to turn the system off. Fail-
ure to do so may lead to an accident, resulting in death or serious injury.
●Vehicle is driven on a road surface which is slippery due to rainy weather, fallen snow, freezing, etc.
●Vehicle is driven on a snow-cov-ered road.
●White (yellow) lines are difficult to see due to rain, snow, fog, dust,
etc.
●Vehicle is driven in a temporary
lane or restricted lane due to con- struction work.
●Vehicle is driven in a construction zone.
●A spare tire, tire chains, etc., are equipped.
●When the tires have been exces-sively worn, or when the tire infla-tion pressure is low.
●When tires of a size other than specified are installed.
●Vehicle is driven in traffic lanes other than that highways and free-
ways.
●When your vehicle is towing a
trailer or during emergency towing
■Preventing LTA system malfunc-
tions and operations performed by mistake
●Do not modify the headlights or
place stickers, etc., on the surface of the lights.
●Do not modify the suspension, etc. If the suspension, etc., needs to be replaced, contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Do not install or place anything on the hood or grille. Also, do not install a grille guard (bull bars, kan-
garoo bar, etc.).
●If your windshield needs repairs,
contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■Conditions in which functions may not operate properly
In the following situations, the func- tions may not operate properly and the vehicle may depart from its lane.
Drive safely by always paying careful attention to your surroundings and operate the steering wheel to correct
the path of the vehicle without relying solely on the functions.
