ning at a low speed for an extended period, such as in heavy traffic, etc.
CAUTION
nAvoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the battery.
lMake sure the jumper cable is connected to the correct terminal and that it
is not unintentionally in contact with any part other than the intended termi-
nal.
l Do not allow the jumper cables to come into contact with the “+” and “-” ter-
minals.

subsides 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.

light goes off and then stop the engine.
If the fan is not operating: Stop the engine immediately and call your local Toyota
dealer.

Look for obvious coolant leaks from the radiator, hoses and
under the vehicle.
Note that water draining from the air conditioning is normal if it has
been used.
Add engine coolant if required.

n
Overheating
If you observe the following, your vehicle may be overheating.
lThe high engine coolant temperature warning light flashes or comes on
or a loss of power is experienced.
l Steam is coming from under the hood.
CAUTION
nTo prevent an accident or injury when inspecting under the hood of
your vehicle
lIf 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 injury such as burns.
l Keep hands and clothing away from the fan and other belts while the
engine is running.
l 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.
NOTICE
nWhen 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.

5-2. Steps to take in an emergency
If the vehicle becomes stuck
nEmergency 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 parking brake and put the shift
lever in 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 to help provide
traction under the tires.
Restart the engine.
If equipped, turn off the VSC ( →P. 140)
Shift the shift lever to D or R (automatic transmission) or 1
or R (manual transmission) and carefully apply the acceler-
ator to free the vehicle.
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.

CAUTION
n
When attempting to free a stuck vehicle
If you choose to rock the vehicle back and forth to free it, make sure the sur-
rounding area is clear, to avoid striking other vehicles, objects or persons.
The vehicle may also lunge forward or lunge back suddenly as it becomes
free. Use extreme caution.
n When shifting the shift lever
Vehicles with automatic transmission: 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 and result in death or serious injury.
NOTICE
nTo avoid damaging the transmission and other components
lAvoid spinning the wheels and do not rev the engine.
l If the vehicle remains stuck after trying these procedures, the vehicle may
require towing to be freed.

5-2. Steps to take in an emergency
If your vehicle has to be stopped in an emergency
CAUTION
nIf the engine has to be turned off while driving
lPower 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.
l Never attempt to remove the key, as doing so will lock the steering wheel.
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.
