Total trailer weight Drawbar load
DThe trailer cargo load should be distrib-
uted so that the drawbar load is more
than 25 kg (55.1 lb.) and more than
4% of the towing capacity. However,
the drawbar load must not exceed the
weight specified on page 222 in Sec-
tion 8.
DThe sum weight of the total curb mass,
driver, passengers, cargo, towing hitch
and drawbar load must not exceed
gross vehicle mass.
DThe load on the rear axle must not
exceed the maximum permissible rear
axle capacity.
Towing capacity has been tested at sea−
level. If you have to go to a high moun-
tain area, keep in mind that the engine
power and towing capacity will decrease.

CAUTION
DThe total trailer weight must not
exceed the towing capacity speci-
fied on page 222 in Section 8. Ex-
ceeding this weight is dangerous.
DTrailer hitch assemblies have differ-
ent weight capacities established by
the hitch manufacturer. Even though
the vehicle may be physically capa-
ble of towing a higher weight, the
operator must determine the maxi-
mum weight rating of the particular
hitch assembly and never exceed
the maximum weight rating speci-
fied for the trailer−hitch. Exceeding
the maximum weight rating set by
the trailer hitch manufacturer can
cause an accident resulting in seri-
ous injuries.

144STARTING AND DRIVING
TIRES
DEnsure that your vehicle’s tires are
properly inflated. See page 201 in Sec-
tion 7−2 and page 226 in Section 8 for
instructions.
DThe trailer tires should be inflated to
the pressure recommended by the trail-
er manufacturer in respect to the total
trailer weight.
TRAILER LIGHTS
DCheck for correct operation of the turn
signals and stop lights each time you
hitch up. Direct splicing may damage
your vehicle’s electrical system and
cause a malfunction of your lights.
BREAK−IN SCHEDULE
DToyota recommends that you do not
tow a trailer with a new vehicle or a
vehicle with any new power train com-
ponent (engine, transmission, differen-
tial, wheel bearing, etc.) for the first
800 km (500 miles) of driving.
MAINTENANCE
DIf you tow a trailer, your vehicle will
require more frequent maintenance due
to the additional load.
DRetighten all fixing bolts of the towing
ball and bracket after approximately
1000 km (600 miles) of trailer driving.
PRE−TOWING SAFETY CHECK
DBe sure not to exceed designated max-
imum load for the ball coupling of the
towing bracket. Please remember that
the ball coupling load will increase the
load on the vehicle. Maximum permissi-
ble rear axle capacity must not be ex-
ceeded.
DMake sure the trailer cargo is securely
loaded so that it cannot shift.
DIf the traffic behind the trailer cannot
be seen properly with the standard rear
view mirrors, additional outside mirrors
will be necessary. Both outside mirrors
must be fitted on folding arms and ad-
justed to give a good rear view at all
times.
TRAILER TOWING TIPS
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:
DBefore starting out, check operation of
the lights and all vehicle−trailer connec-
tions. After driving a short distance,
stop and recheck the lights and con-
nections. Before actually towing a trail-
er, practice turning, stopping and back-
ing with a trailer in an area away from
traffic until you learn the feel.
DBecause stopping distance may be in-
creased, vehicle−to−vehicle distance
should be increased when towing a
trailer. For each 10 km/h (6 mph) of
speed, allow at least one vehicle and
trailer length between you and the ve-
hicle ahead. Avoid sudden braking as
you may skid, resulting in jackknifing
and loss of control. This is especially
true on wet or slippery surfaces.
DAvoid jerky starts or sudden accelera-
tion. Prevent excessive clutch slippage
by keeping engine rpm low and not
racing the engine. Always start out in
first gear.
DAvoid jerky steering and sharp turns.
The trailer could hit your vehicle in a
tight turn. Slow down before making a
turn to avoid the necessity of sudden
braking.
Dyna100/150_EE

STARTING AND DRIVING145
DBacking with a trailer 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 right to
move the trailer to the right. (This pro-
cedure is generally opposite to that
when backing without a trailer.) Also,
just turn the steering wheel a little at
a time, avoiding sharp or prolonged
turning. Have someone guide you when
backing to reduce the risk of an acci-
dent.
DRemember that when making a turn,
the trailer wheels will be closer than
the vehicle wheels to the inside of the
turn. Therefore, compensate for this by
making a larger than normal turning
radius with your vehicle.
DCrosswinds and rough roads will ad-
versely affect handling of your vehicle
and trailer, causing sway. Pay attention
to the rear from time to time to pre-
pare yourself for being passed by large
trucks or buses, which may cause your
vehicle and trailer to sway. If swaying
happens, firmly grip the steering wheel
and reduce speed immediately but
gradually. Never increase speed. If it is
necessary to reduce speed, brake
slowly. Steer straight ahead. If you
make no extreme correction with the
steering or brakes, the vehicle and
trailer will stabilize.
DBe careful when passing other ve-
hicles. Passing requires considerable
distance. After passing a vehicle, do
not forget the length of your trailer and
be sure you have plenty of room be-
fore changing lanes.
DTo maintain engine braking efficiency,
when using engine braking, do not use
fifth gear.
DBecause of the added load of the trail-
er, your vehicle’s engine may overheat
on hot days (at temperatures over
30_C[85_F]) when going up a long or
steep grade with a trailer. If the engine
coolant temperature gauge indicates
overheating, pull off the road and stop
in a safe spot. Refer to “If your vehicle
overheats” on page 156 in Section 4.
DAlways place wheel blocks under both
the vehicle and trailer wheels when
parking. Apply the parking brake firmly.
Put the transmission in first or reverse.
Avoid parking on a slope with a trailer,
but if it cannot be avoided, do so only
after performing the following:
1. Apply the brakes and hold.
2. Have someone place wheel blocks un-
der both the vehicle and trailer wheels.
3. When the wheel blocks are in place,
release your brakes slowly until the
blocks absorb the load.
4. Apply the parking brake firmly.
5. Shift into first or reverse and turn off
the engine.
When restarting out after parking on a
slope:
1. With the clutch pedal depressed, start
the engine.
2. Shift into gear.
3. Release the parking brake and slowly
pull or back away from the wheel
blocks. Stop andapply your brakes.
4. Have someone retrieve the blocks.

146STARTING AND DRIVING
CAUTION
DObserve the legal maximum speeds
for trailer towing.
DSlow down and downshift before
descending steep or long downhill
grades. Do not make sudden down-
shifts while descending steep or
long downhill grades.
DAvoid holding the brake pedal down
too long or too frequently. This
could cause the brakes to overheat
and result in reduced braking effi-
ciency.
Improving fuel economy is easy—just take
it easy. It will help make your vehicle last
longer, too. Here are some specific tips
on how to save money on both fuel and
repairs:
DKeep your tires inflated at the cor-
rect pressure.Underinflation causes
tire wear and wastes fuel. See page
201 in Section 7−2 for instructions.
DDo not carry unneeded weight in
your vehicle.Excess weight puts a
heavier load on the engine, causing
greater fuel consumption.
DAvoid lengthy warm−up idling.Once
the engine is running smoothly, begin
driving—but gently. Remember, howev-
er, that on cold winter days this may
take a little longer.
DAccelerate slowly and smoothly.
Avoid jackrabbit starts. Get into high
gear as quickly as possible.
DAvoid long engine idling.If you have
a long wait and you are not in traffic,
it is better to turn off the engine and
start again later.
DAvoid engine lugging or over−rev-
ving.Use a gear position suitable for
the road on which you are travelling.
DAvoid continuous speeding up and
slowing down.Stop−and−go driving
wastes fuel.
DAvoid unnecessary stopping and
braking.Maintain a steady pace. Try
to time the traffic signals so you only
need to stop as little as possible or
take advantage of through streets to
avoid traffic lights. Keep a proper dis-
tance from other vehicles to avoid sud-
den braking. This will also reduce wear
on your brakes.
DAvoid heavy traffic or traffic jams
whenever possible.
DDo not rest your foot on the clutch
or brake pedal.This causes premature
wear, overheating and poor fuel econo-
my.
