■Starting the engine when the battery is discharged (vehicles with a
Multidrive)
The engine cannot be started by push-starting.
■ To prevent battery discharge
● Turn off the headlights and the audio system while the engine is off.
● 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.)
■ Precautions when the battery is discharged (vehicles with a smart entry
& start system)
● In some cases, it may not be possible to unlock the doors using the smart
entry & start system when the battery is discharged. Use the wireless
remote control or the mechanical key to lock or unlock the doors.
● The engine may not start on the first attempt after the battery has recharged
but will start normally after the second attempt. This is not a malfunction.
● The engine switch mode is memorized by the vehicle. When the battery is
reconnected, the system will return to the mode it was in before the battery
was discharged. Before disconnecting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.

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 + 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, and
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 converter
(gasoline engine) or catalytic conv erter (diesel engine) 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. 439)
comes on or flashes, or a loss of engine power is experienced. (For
example, the vehicle speed 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 sufficiently, inspect the hoses and
radiator core (radiator) for any leaks.
If a large amount of coolant leaks, immediately contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional.
The following may indicate that your vehicle is overheating:

The coolant level is satisfactory if it is between the “FULL” and
“LOW” lines on the reservoir.
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
dealer or repairer, or another duly qualified and equipped profes-
sional.
If the fan is operating:
Have the vehicle inspected at the nearest authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.

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 coolant 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.

Reinstall the cover, and then hook the rubber strip’s groove onto the
cover.
Start the engine. ( P. 182, 185)
If the engine does not start after the above steps have been performed,
wait for 10 seconds and then try steps 3 and 5 again. If the engine still
does not start, contact any authorized Toyota dealer or repairer, or another
duly qualified and equipped professional.
After starting the engine, depress the accelerator pedal lightly until the
engine runs smoothly.

NOTICE
■ When restarting the engine
● Do not crank the engine before refueling and operating the priming pump.
This may damage the engine and fuel system.
● Vehicles without a smart entry & start system: Do not crank the engine for

Remove the mud, snow or sand from around the front wheels.
Place wood, stones or some other material under the front wheels
to help provide traction.
Restart the engine.
Shift the shift lever to D or R (Multidrive) or 1 or R (manual trans-
mission) and release the parking brake. Then, while exercising cau-
tion, depress 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 the switch to turn off TRC.
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.

WARNING
■When attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the
surrounding area is clear to avoid striking other vehicles, objects or people.
The vehicle may also lunge forward or lunge back suddenly as it becomes
free. Use extreme caution.
■ When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may
cause an accident resulting in death or serious injury.
NOTICE
■ To avoid damage to the transmission and other components
● Avoid spinning the front wheels and depressing the accelerator pedal
more than necessary.
● If the vehicle remains stuck even after these procedures are performed,
the vehicle may require towing to be freed.
