Tire information
Ensure that your vehicle's tires are properly inflated. Adjust the tire pres-
sure to the recommended pressure. (P. 669)
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.
Trailer lights
Check that the turn signal lights and stoplights are operating correctly every
time you hitch up the trailer. Directly 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. 342)
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 com-
pared to normal driving.
Retighten all bolts securing the hitching ball and bracket after towing for
approximately 1000 km (600 miles).

Where to go for the maintenance service?
In order to maintain your vehicle in the best possible condition, Toyota rec-
ommends that all repairs and service operations be carried out by autho-
rized Toyota dealers or repairers or other duly qualified and equipped
professionals. For repairs and services covered by your warranty, please
visit an authorized Toyota dealer or repairer, who will use genuine Toyota
parts in repairing any difficulties you may encounter. There can also be
advantages in utilizing authorized Toyota dealers or repairers for non-war-
ranty repairs and services, as members of the Toyota network will be able to
expertly assist you with any difficulties you may encounter.
Your Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional will perform all of the scheduled maintenance on your vehicle reli-
ably and economically due to their experience with Toyota vehicles.
Does your vehicle need repairs?
Be on the alert for changes in performance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
Engine misses, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A fluid leak under the vehicle (However, water dripping from the air condi-
tioning system after use is normal.)
Change in exhaust sound (This may indicate a dangerous carbon mon-
oxide leak. Drive with the windows open and have the exhaust system
checked immediately.)
Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
Vehicle pulls to one side when driving straight on a level road
Strange noises related to suspension movement
Loss of brake effectiveness, spongy feeling brake pedal or clutch pedal
(vehicles with a manual transmission), pedal almost touches the floor,
vehicle pulls to one side when braking
Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional as
soon as possible. Your vehicle may need adjustment or repair.

When to replace your vehicle’s tires
Tires should be replaced if:
You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric, and bulges indicating internal damage
A tire goes flat repeatedly or cannot be properly repaired due to the size
or location of a cut or other damage
If you are not sure, consult with any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional.
Tire life
Any tire over 6 years old must be checked by a qualified technician even if it
has seldom or never been used or damage is not obvious.
Low profile tires (vehicles with 195/50R16 tires)
Generally, low profile tires will wear more rapidly and tire grip performance
will be reduced on snowy and/or icy roads when compared to standard tires.
Be sure to use snow tires or tire chains on snowy and/or icy roads and drive
carefully at a speed appropriate for road and weather conditions.
If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
Vehicles with a spare tire of the same wheel type as the
installed tires
Rotate the tires in the order
shown.
To equalize tire wear and help
extend tire life, Toyota recom-
mends that tire rotation is car-
ried out approximately every
10000 km (6000 miles).

NOTICE
Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire inflation pressure, reducing the
cushioning ability of the tires. In addition, driving on rough roads may cause
damage to the tires themselves, as well as the vehicle’s wheels and body.
Low profile tires (vehicles with 195/50R16 tires)
Low profile tires may cause greater damage than usual to the tire wheel
when sustaining impact from the road surface. Therefore, pay attention to
the following:
Be sure to use proper tire inflation pressure. If tires are under-inflated, they
may be damaged more severely.
Avoid potholes, uneven pavement, curbs and other road hazards. Failure
to do so may lead to severe tire and wheel damage.
If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Tire inflation pressure
Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
Reduced fuel efficiency
Reduced driving comfort and tire life
Reduced safety
Damage to the drive train
If a tire needs frequent inflating, have it checked by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not been
driven for more than 1.5 km or 1 mile, you will get an accurate cold tire
inflation pressure reading.
Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation
pressure that is even just a few pounds off can affect ride quality and
handling.
Do not reduce tire inflation pressure after driving. It is normal for tire infla-
tion pressure to be higher after driving.
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is
balanced.
Make sure to maintain proper tire inflation pressure. Tire inflation
pressure should be checked at least once per month. However, Toy-
ota recommends that tire inflation pressure be checked once every
two weeks. (P. 669)

CAUTION
Proper inflation is critical to save tire performance
Keep your tires properly inflated. Otherwise, the following conditions may
occur and result in an accident causing death or serious injury:
Excessive wear
Uneven wear
Poor handling
Possibility of blowouts resulting from overheated tires
Poor sealing of the tire bead
Wheel deformation and/or tire separation
A greater possibility of tire damage from road hazards
NOTICE
When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
Without the valve caps, dirt or moisture could get into the valve and cause
air leakage, which could result in an accident. If the caps are lost, replace
them as soon as possible.
