17-inch tires
Use the correct tire chain size when mounting the tire chains. Chain
size is regulated for each tire size.
Side chain
3 mm (0.12 in.) in diameter
10 mm (0.39 in.) in width
30 mm (1.18 in.) in length
Cross chain
4 mm (0.16 in.) in diameter
14 mm (0.55 in.) in width
25 mm (0.98 in.) in length
18-inch tires or 19-inch tires
Tire chains cannot be mounted as the space between the tire and
body is too narrow.
Snow tires should be used instead.
Regulations regarding the use of tire chains vary depending on loca-
tion and type of road. Always check local regulations before in stalling
chains.
■ Tire chain installation
Observe the following precautions when installing and removing chains:
● Install and remove tire chains in a safe location.
● Install tire chains on the front tires only. Do not install tire chains on the rear
tires.
● Install tire chains on front tires as tightly as possible. Retighten chains after
driving 0.5 - 1.0 km (1/4 - 1/2 mile).
● Install tire chains following the instructions provided with the tire chains.

WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of acciden ts.
Failure to do so may result in a loss of vehicle control and ca use death or
serious injury.
● Use tires of the specified size.
● Maintain the recommended level of air pressure.
● Do not drive at speeds in excess of the speed limit or the speed limit spec-
ified for the snow tires being used.
● Use snow tires on all, not just some wheels.
■ Driving with tire chains
Observe the following precautions to reduce the risk of acciden ts.
Failure to do so may result in the vehicle being unable to be d riven safely,
and may cause death or serious injury.
● Do not drive in excess of the speed limit specified for the tire chains being
used, or 50 km/h (30 mph), whichever is lower.
● Avoid driving on bumpy road surfaces or over potholes.
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
● Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
NOTICE
■ Repairing or replacing snow tires
Request repairs or replacement of snow tires from any authorize d Toyota
retailer or Toyota authorized repairer, or any reliable repaire r or legitimate
tire retailers.
This is because the removal and attachment of snow tires affect s the opera-
tion of the tire pressure warning valves and transmitters.
■ Fitting tire chains
The tire pressure warning valves and transmitters may not funct ion correctly
when tire chains are fitted.

Maintenance and care
■Where to go for maintenance service?
In order to maintain your vehicle in the best possible conditio n, Toyota recom-
mends that maintenance service operations as well as other insp ections and
repairs be carried out by authorized Toyota retailers or repair ers or other duly
qualified and equipped professionals. For repairs and services covered by
your warranty, please visit an authorized Toyota retailers or r epairer, who will
use genuine Toyota parts in repairing any difficulties you may encounter.
There can also be advantages in utilizing authorized Toyota ret ailers or
repairers for non-warranty repairs and services, as members of the Toyota
network will be able to expertly assist you with any difficulti es you may
encounter.
Your authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer will perform all of the scheduled maintenance on your vehicle reliably
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 visu al 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 monoxide
leak. Drive with the windows open and have the exhaust system c hecked
immediately.)
● Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
● Vehicle pulls to one side when driven straight on a level road
● Strange noises related to suspension movement
● Loss of brake effectiveness, spongy feeling brake pedal, pedal almost
touches the floor, vehicle pulls to one side when braking
● Engine coolant temperature continually higher than normal (P. 686, 757)
If you notice any of these clues, take your vehicle to any auth orized Toyota
retailer or Toyota authorized repairer, or any reliable repaire r as soon as pos-
sible. Your vehicle may need adjustment or repair.

Tires
Check if the treadwear indicators are showing on the tires. Also check
the tires for uneven wear, such as excessive wear on one side o f the
tread.
Check the spare tire condition and pressure if not rotated.
New tread
Worn tread
Treadwear indicator
The location of treadwear indicators is shown by a “TWI” or “ ” mark, etc.,
molded into the sidewall of each tire.
Replace the tires if the treadwear indicators are showing on a tire.
Replace or rotate tires in accordance with maintenance sched-
ules and treadwear.

Maintenance and care
Rotate the tires in the order shown.
To equalize tire wear and help extend tire life, Toyota recommends that tire
rotation is carried out approximately every 10000 km (6000 mile s).

Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valves and transmitters to detect low tir e infla-
tion pressure before serious problems arise.
If the tire pressure drops below a predetermined level, the dri ver is
warned by a warning light. ( P. 686)
◆Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves an d
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new ID codes must be registered in the tire pressure
warning computer and the tire pressure warning system must be
initialized. Have tire pressure warning valve and transmitter I D
codes registered by any authorized Toyota retailer or Toyota au tho-
rized repairer, or any reliable repairer. ( P. 620)
◆Initializing the tire pressure warning system
When the tire size is changed, the tire pressure warning system
must be initialized.
When the tire pressure warning system is initialized, the curre nt tire
inflation pressure is set as the benchmark pressure.

C-HR_HV_OM_Europe_OM10720E
◆Registering ID codes
The tire pressure warning valve and transmitter is equipped wit h a
unique ID code. When replacing a tire pressure warning valve an d
transmitter, it is necessary to register the ID code. Have the ID code
registered by any authorized Toyota retailer or Toyota authoriz ed
repairer, or any reliable repairer.
■ When to replace your vehicle’s tires
Tires should be replaced if:
● The treadwear indicators are showing on a tire.
● 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 retaile r or Toyota
authorized repairer, or any reliable repairer.
■ Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitt er is not regis-
tered, the tire pressure warning system will not work properly. After driving for
about 10 minutes, the tire pressure warning light blinks for 1 minute and stays
on to indicate a system malfunction.
■ Tire life
Any tire over 6 years old must be checked by a qualified techni cian even if it
has seldom or never been used, or damage is not obvious.
■ Routine tire inflation pressure check
The tire pressure warning system does not replace routine tire inflation pres-
sure checks. Make sure to check tire inflation pressure as part of your routine
of daily vehicle checks.
■ If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
