If the shift lever cannot be shifted from P (vehicles with an automatic transmission)
If the shift lever cannot be shifted with your foot on the brake pedal,
there may be a problem with the shift lock system (a system to pre-
vent accidental operation of the shift lever). Have the vehicle
inspected by your Toyo ta dealer immediately.
The following steps may be used as an emergency measure to
ensure that the shift lever can be shifted:
Set the parking brake.
Turn the engine switch to the “ACC” position.
Depress the brake pedal.
Pry the cover up with a flat-
head screwdriver or equiva-
lent tool.
To prevent damage to the
cover, cover the tip of the

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.
■ 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 you see steam:
Stop the engine. Carefully lift the hood after the steam sub-
sides and then restart the engine.
If you do not see steam:
Leave the engine running and carefully lift the hood.
Check to see if the cooling fan is operating.
If the fan is operating:
Wait until the high engine coolant temperature warning light
goes off and then stop the engine.
If the fan is not operating:
Stop the engine immediately and call your Toyota dealer.
After the engine has cooled
down sufficiently, check the
engine coolant level and
inspect the radiator core (radi-
ator) for any leaks.

Overheating
If you observe the following, your vehicle may be overheating:
●The high engine coolant temperature warning light flashes or comes on
or a loss of power is experienced.
● Steam comes out from under the hood.
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 away from the fan and drive belt while the engine
is running.
● Do not loosen the radiator cap while the engine and radiator are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is
unavailable. ( →P. 347)
Have the vehicle inspected at the nearest Toyota dealer as soon as
