ture repair kit if the damage is
caused by a nail or screw pass-
ing through the tire tread.

screw from the tire. Remov-
ing the object may widen the
opening and disenable emer-
gency repair with the kit.

■ When exchanging the battery (vehicles with Stop & Start system)
Use a genuine battery specifically designed for use with the Stop & Start sys-
tem or a battery with equivalent specifications to a genuine battery. If an
unsupported battery is used, Stop & Start system functions may be restricted
to protect the battery. Also, battery performance may decrease and the
engine may not be able to restart. Contact any authorized Toyota retailers or
Toyota authorized repairers, or any reliable repairers for details.
■ When replacing the battery
● Use a battery that conforms to European regulations.
● Use a battery that the case size is same as the previous one, 20 hour rate
capacity (20HR) is equivalent or greater, and performance rating (CCA) is
equivalent or greater.
Check the label on top of the battery for the battery size and specifications
(ex. LN2, 60Ah, 520A).
• If the sizes differ, the battery cannot be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehi-
cle is not used is a short time, the battery may discharge and the engine
may not be able to start.
● For details, consult any authorized Toyota retailers or Toyota authorized
repairers, or any reliable repairers.

Add coolant if necessary.
Water can be used in an emergency if coolant is unavailable.
Start the engine and turn the air conditioning system on to check
that the radiator cooling fan operates and to check for coolant leaks
from the radiator or hoses.
The fan operates when the air conditioning system is turned on immedi-
ately after a cold start. Confirm that the fan is operating by checking the fan
sound and air flow. If it is difficult to check these, turn the air conditioning
system on and off repeatedly.
(The fan may not operate in freezing temperatures.)
If the fan is not operating:
Stop the engine immediately and contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
If the fan is operating:
Have the vehicle inspected at the nearest authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer.
