Trailer towing
◆Weight limits
Check the allowable towing capacity, GVM (Gross Vehicle Mass),
MPAC (Maximum Permissible Axle Capacity), and permissible
drawbar load before towing. (P. 646)
◆Towing hitch/bracket
Toyota recommends the use of the Toyota hitch/bracket for your
vehicle. Other products of a suitable nature and comparable quality
may also be used.
Your vehicle is designed primarily as a passenger carrying vehi-
cle. Towing a trailer will have an adverse effect on handling, per-
formance, braking, durability, and fuel consumption. Your safety
and satisfaction depend on the proper use of correct equipment
and cautions driving habits. For your safety and the safety of
others, do not overload the vehicle or trailer.
To tow a trailer safely, use extreme care and drive the vehicle in
accordance with the trailer’s characteristics and operating con-
ditions.
Toyota warranties do not apply to damage or malfunction
caused by towing a trailer for commercial purposes.
Ask your local authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer for further details before towing,
as there are additional legal requirements in some countries.

Total trailer weight and permissible drawbar load
Total trailer weight
Weight of the trailer itself plus
the trailer load should be
within the maximum towing
capacity. Exceeding this
weight is dangerous.

(P. 646)
When towing a trailer, use a
friction coupler or friction sta-
bilizer (sway control device).
Permissible drawbar load
Allocate the trailer load so that the drawbar load is greater than
25 kg (55.1 lb.) or 4% of the towing capacity. Do not let the draw-
bar load exceed the indicated weight. (P. 646)

■Tire information
● Increase the tire inflation pressure to 20.0 kPa (0.2 kgf/cm2 or bar, 3 psi)
greater than the recommended value when towing. ( P. 659)
● Increase the air pressure of the trailer tires in accordance with the total
trailer weight and according to the values recommended by the manufac-
turer of your trailer.
■ Tr a i l e r l i g h ts
Check that the turn signal lights and stoplights are operating correctly every
time you hitch up the trailer. Direct ly wiring up to your vehicle may damage
the electrical system and stop the lights from functioning correctly.
■ 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 and 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 the total load exerted
on the vehicle is within the range of the weight limits. ( P. 232)
● Ensure that the trailer load is secure.
● Supplementary outside rear view mirrors 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 burden placed on the vehicle compared to
normal driving.
● Retighten all bolts securing the hitching ball and bracket after towing for
approximately 1000 km (600 miles).
NOTICE
■ When the rear bumper strengthening 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 section concerned and may result in dam-
age. Apply a rust inhibitor to parts that will come in contact when attaching a
steel bracket.

2384-1. Before driving
YARIS_F_OM_Europe_OM52A54E
Your vehicle will handle differently when towing a trailer. In order to
avoid accident, death or serious injury, keep the following in mind
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 coupled trailer
●Get the feel for turning, stopping and reversing with the trailer
coupled by practicing in an area with no or light traffic.
●When 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 normally 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. Frequently check behind when mov-
ing 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 exe-
cuting lane changes.
■Transmission information
Vehicles with a Multidrive
To maintain engine braking efficiency, when using engine braking,
do not use the transmission in D. Transmission shift gear position
must be in 4 in the M mode. (P. 252)
Vehicles with a manual transmission
To maintain engine braking efficiency, when using engine braking,
do not use the transmission in 5 and 6 (vehicles with a 6-speed
manual transmission) gear. (P. 260)
■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
high engine coolant temperature warning light flashes or comes on,
turn the air conditioning off immediately, leave the road and stop the
vehicle in a safe place. (P. 639)
■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
(Multidrive) or 1 or R (manual transmission).

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. 2 3 2 )
■ Vehicle speed in towing
Observe the legal maximum speeds for trailer towing.
■ Before descending hills or long declines
Reduce speed and downshift. However, 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 cruise control: Do not use cruise control when you are tow-
ing.
● Vehicles with a compact spare tire: Do not tow a trailer when the compact
spare tire is installed on your vehicle.
● Vehicles with an emergency tire puncture repair kit: Do not tow a trailer
when the tire installed is repaired with the emergency tire puncture repair
kit.
NOTICE
■ Do not directly splice trailer lights
Directly splicing trailer lights may damage your vehicle’s electrical system
and cause a malfunction.
