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).

6186-3. Do-it-yourself maintenance
C-HR_HV_OM_Europe_OM10720E
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.
