If the vehicle battery is discharged
If you have a set of jumper (or booster) cables and a second vehicle
with a 12-volt battery, you can jump start your vehicle by following the
steps below.
Open the hood. ( →P. 356)
Connect the jumper cables according to the following procedure:
Connect a positive jumper cable clamp to the positive (+) battery
terminal on your vehicle.
Connect the clamp on the other e nd of the positive cable to the
positive (+) battery terminal on the second vehicle.
Connect a negative cable clamp to the negative (-) battery termi-
nal on the second vehicle.
Connect the clamp at the other end of the negative cable to a
solid, stationary, unpainted metallic point away from the battery
and any moving parts, as shown in the illustration.
The following procedures may be used to start the engine if the

When trouble arises
Start the engine of the second vehicle. Increase the engine speed
slightly and maintain at that level for approximately 5 minutes to
recharge the batter y of your vehicle.
Maintain the engine speed of t he second vehicle and start the
engine of your vehicle.
Once the vehicle’s engine has star ted, remove the jumper cables in
the exact reverse order from which they were connected.
Once the engine starts, have the v ehicle inspected at your Toyota
dealer as soon as possible.
■ Starting the engine when the batt ery is discharged (vehicles with an
automatic transmission)
The engine cannot be started by push-starting.
■ To prevent battery discharge
●Turn off the headlights and the audio system while the engine is not running.
● Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.
■ Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)

WARNING
■Avoiding battery fires or explosions
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 anything other than the intended ter-
minal.
● Do not allow the other end of the jumper cable connected to the “+” termi-
nal 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 contact
with each other.
● Do not smoke, use matches, cigarette 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 pre-
cautions when handling the battery:
● 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 attention.
Place a wet sponge or cloth over the affected area until medical attention
can be received.
● Always wash your hands after handling the battery support, terminals, an\
d
other battery-related parts.
● Do not allow children near the battery.
■ To prevent damage to the vehicle
Do not pull- or push-start the vehicle as the three-way catalytic conver\
ter
may overheat and become a fire hazard.
NOTICE
■When handling jumper cables
When connecting the jumper cables, ensure that they do not become entan-
gled in the cooling fans or engine drive belt.

When trouble arises
If your vehicle overheats
●The high engine coolant temperature warning light ( →P. 422)
comes on or flashes, or a loss of engine power is experienced. (For
example, the vehicle sp eed does not increase.)
● Steam comes out from under the hood.
Stop the vehicle in a safe place and turn off the air conditioning sys-
tem, and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the engine has cooled
down sufficient ly, inspect the
hoses and radiator core (radia-
tor) for any leaks.
Radiator
Cooling fan
If a large amount of coolant leaks,
immediately contact your Toyota
dealer.
The coolant level is satisfactory
if it is between the “FULL” and
“LOW” lines on the reservoir.Reservoir

4548-2. Steps to take in an emergency
Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the engine and turn the air conditioning system on to check
that the radiator cooling fan opera tes 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 your Toyota dealer.
If the fan is operating:
Have the vehicle in spected at the nearest Toyota dealer.

WARNING
■To prevent an accident or injury 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 (especially a tie, a scarf or a muffler) away from
the fan and belts while the engine is operating.
● Do not loosen the radiator cap or the reservoir cap while the engine and\
radiator are hot.
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 additives.

4568-2. Steps to take in an emergency
If the vehicle becomes stuck
Stop the engine. Set the parking brake and shift the shift lever to P
(automatic transmission) or N (manual transmission).
Remove the mud, snow or sand from around the front wheels.
Place wood, stones or some othe r material under the front wheels
to help provide traction.
Restart the engine.
Shift the shift lever to D or R (a utomatic transmission) or 1 or R
(manual transmission) and releas e the parking brake. Then, while
exercising caution, depre ss the accelerator pedal.
■When it is difficult to free the vehicle
■ Emergency hooks
Carry out the following procedures if the tires spin or the vehicle
becomes stuck in mud, dirt or snow:
Press to turn off TRAC.
When your vehicle becomes stuck and
cannot move, the emergency hooks are
used for another vehicle to pull your vehi-
cle out in an emergency.
Your vehicle is not designed to tow
another vehicle.
