7-2. Steps to take in an emergency
to the mode it was in before the bat-
tery was discharged. Before discon- necting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the bat-tery discharged, be especially careful
when reconnecting the battery.
■When replacing the battery
●Use a battery that conforms to Euro-
pean 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, 345A). • 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 bat-
tery may discharge and the engine may not be able to start.
●For details, consult any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
WARNING
■When removing the battery ter-minals
Always remove the negative (-) termi-
nal first. If the positive (+) terminal contacts any metal in the surrounding area when the positive (+) terminal is
removed, a spark may occur, leading to a fire in addition to electrical shocks and death or serious injury.
■Avoiding battery fires or explo-sions
Observe the following precautions to prevent accidentally igniting the flam-mable gas that may be emitted from
the battery:
●Make sure each jumper cable is connected to the correct terminal and that it is not unintentionally in
contact with any other than the intended terminal.
●Do not allow the other end of the jumper cable connected to the “+” terminal to come into contact with
any other parts or metal surfaces in the area, such as brackets or unpainted metal.
●Do not allow the + and - clamps of the jumper cables to come into con-
tact with each other.
●Do not smoke, use matches, ciga-
rette lighters or allow open flame near the battery.
■Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while
related parts contain lead and lead compounds. Observe the following precautions when handling the bat-
tery:
●When working with the battery,
always wear safety glasses and take care not to allow any battery fluids (acid) to come into contact
with skin, clothing or the vehicle body.
●Do not lean over the battery.
●In the event that battery fluid comes
into contact with the skin or eyes, immediately wash the affected area with water and seek medical atten-
tion. Place a wet sponge or cloth over the affected area until medical attention can be received.
●Always wash your hands after han-dling the battery support, terminals,
and other battery-related parts.
●Do not allow children near the bat-
tery.

7-2. Steps to take in an emergency
When trouble arises
M15A-FKS engine
6 Start the engine and turn the air
conditioning system on to check
that the radiator cooling fan
operate and to check for coolant
leaks from the radiator or hoses.
The fan operate when the air condition- ing system is turned on immediately 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.)
7 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
any authorized Toyota retailer or
Toyota authorized repairer, or
any reliable repairer.
WARNING
■When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
●If steam is seen coming from under the hood, do not open the hood until the steam has subsided. The
engine compartment may be very hot.
●Keep hands and clothing (espe-cially a tie, a scarf or a muffler) away from the fan and belts. Failure
to do so may cause the hands or clothing to be caught, resulting in serious injury.
●Do not loosen the coolant reservoir caps while the engine and radiator
are hot. High temperature steam or coolant could spray out.
NOTICE
■When adding engine coolant
Add coolant slowly after the engine has cooled down sufficiently. Adding
cool coolant to a hot engine too quickly can cause damage to the engine.
■To prevent damage to the cooling system
Observe the following precautions:
●Avoid contaminating the coolant
with foreign matter (such as sand or dust etc.).
●Do not use any coolant additive.
