5-2. Steps to take in an emergency
■
Starting the engine when the battery 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 air conditioning system while the engine is
off.
● Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic.
■ When the battery is removed or di scharged (vehicles with an alarm
system)
Make sure that the key is not inside the vehicle when recharging or replacing
the battery. The key may be locked in the vehicle if the alarm is activated.
( P. 75)
■ 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.)
Maintain the engine speed of the second vehicle and start
the engine of your vehicle by turning the engine switch to
the “ON” position.
Once the vehicle’s engine has started, remove the jumper
cables in the exact reverse or der from which they were con-
nected.
Once the engine starts, have the vehicle inspected at your Toyota
dealer as soon as possible.

If your vehicle overheats
The following may indicate that your vehicle is overheating.
●The high engine coolant te mperature warning light (P. 306)
comes on or flashes, or a loss of engine power is experienced.
(For example, the vehicl e speed does not increase.)
● Steam comes out from under the hood.
Follow the correction pro cedure as described below.
Stop the vehicle in a safe place and turn off the air condi-
tioning system, 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 sufficiently, inspect the
hoses and radiator core (radi-
ator) for any leaks.
Radiator
Cooling fan
If a large amount of coolant
leaks, immediately contact
your Toyota dealer.
The coolant level is satisfac-
tory if it is between the “FULL”
and “LOW” lines on the reser-
voir.Reservoir

5-2. 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 ai
r 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
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.)
If the fan is not operating: Stop the engine immediately and contact your Toyota
dealer.
If the fan is operating: Have the vehicle inspected at the nearest Toyota dealer.

CAUTION
■To prevent an accident or injury when inspecting under the hood of
your vehicle
● 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, caus-
ing serious injuries such as burns.
● Keep hands and clothing (especially a tie, a scarf or a muffler) away from
the fans and belts. Failure to do so may cause the hands or clothing to be
caught, resulting in serious injury.
● Do not loosen the radiator cap and the coolant reservoir cap while the
engine and radiator are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
NOTICE
■When adding engine coolant
Wait until the engine has cooled down before adding engine coolant.
When adding coolant, do so slowly. 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 commercially available coolant additives.

If the vehicle becomes stuck
■Emergency hook
Carry out the following procedures if the tires spin or the vehicle
becomes stuck in mud, dirt, or snow:
Stop the engine. Set the parki ng brake and shift the shift
lever to P (vehicles with an automatic transmission) or N
(vehicles with a manual transmission).
Remove the mud, snow or sand from around the stuck tire.
Place wood, stones or some other material under the tires
to help provide traction.
Restart the engine.
Shift the shift lever to the D or R position (vehicles with an
automatic transmission) or 1 or R position (vehicles with a
manual transmission) and carefully apply the accelerator to
free the vehicle.
Turn off TRAC and VSC if these functions are hampering your
attempts to free the vehicle. ( P. 164)
When your vehicle becomes stuck and
cannot move, the emergency hook is
used for another vehicle to pull your vehi-
cle out in an emergency.
Your vehicle is not designed to tow
another vehicle.

5-2. Steps to take in an emergency
If your vehicle has to be stopped in an emergency
Only in an emergency, such as if it becomes impossible to stop the
vehicle in the normal way, stop the vehicle using the following pro-
cedure:
Steadily step on the brake pedal with both feet and firmly
depress it.
Do not pump the brake pedal repeatedly as this will increase the
effort required to slow the vehicle.
Shift the shift lever to N.
If the shift lever is shifted to N After slowing down, stop the vehi cle in a safe place by the
road.
Stop the engine.
If the shift lever cannot be shifted to N Keep depressing the brake pedal with both feet to reduce
vehicle speed as much as possible.
Stop the engine by turning the
engine switch to the “ACC”
position.
Stop the vehicle in a safe place by the road.

CAUTION
■If the engine has to be turned off while driving
●Power assist for the brakes and steering wheel will be lost, making the
brake pedal harder to depress and the steering wheel heavier to turn.
Decelerate as much as possible before turning off the engine.
● Never attempt to remove the key, as doing so will lock the steering wheel.
