IS250/220d/200d_EE
Avoiding a discharged battery
Turn off the headlights and the audio 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, etc.
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 certain electrical appliances. If the vehicle is left for a long time, the
battery may discharge, and the engine may be unable to start. (The bat-
tery recharges automatically during driving.)
CAUTION
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 the jumper cable is connected to the correct terminal and that it
is not unintentionally in contact with any part other than the intended ter-
minal.
Do not allow the jumper cables to come into contact with the “+” and “-”
terminals.
Do not allow open flame or use matches, cigarette lighters or smoke near
the battery.

If your vehicle overheats
If your engine overheats:
Stop the vehicle in a safe place and turn off the automatic
air conditioning system.
Check to see if steam is coming out from under the hood.
If you see steam:
Stop the engine. Carefully lift the hood after the steam
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 fans are operating.
If the fans are operating:
Wait until the temperature of the engine (shown on the
instrument cluster) begins to fall and then stop the
engine.
If the fans are not operating:
Stop the engine and call any authorized Lexus dealer
or repairer, or another duly qualified and equipped pro-
fessional.
After the engine has cooled
down sufficiently, check the
engine coolant level and
inspect the radiator core
(radiator) for any leaks.
If the engine compartment
cover needs to be removed:

Overheating
If you observe the following, your vehicle may be overheating.
The engine coolant temperature gauge enters the red zone or a loss of
power is experienced.
Steam is coming 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 injury such as burns.
Keep hands and clothing away from the fans and other belts while the
engine is running.
Do not loosen the radiator cap (IS250), or the coolant reservoir cap
(IS220d and IS200d) 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
emergency if engine coolant
is unavailable.
(P. 5 4 4)
Have the vehicle checked at the nearest authorized Lexus dealer
or repairer, or another duly qualified and equipped professional,
as soon as possible.

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.

If you run out of fuel and the engine stalls (IS220d and IS200d)
NOTICE
When restarting the engine
Do not crank the engine before refueling and priming the fuel system. This
may damage the engine and fuel system.
If you run out of fuel and the engine dies:
Refuel your vehicle.
Prime the fuel system by
using the satellite switches.
Push “” or “” to select prim-
ing operation mode. ( )
Press the “ON/OFF” button to
select “ON”. ( )
The priming operation will
start.
Wait for 1 minute and start the engine. (P. 156)
The priming operation will automatically stop when the engine
starts.
If the engine does not start after the above steps performed,
wait for 10 seconds and try step 2 and step 3 again. If the
engine still does not start, contact any authorized Lexus dealer
or repairer, or another duly qualified and equipped profes-
sional.

If the vehicle becomes stuck
CAUTION
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.
When shifting the shift lever
With automatic transmission vehicles, 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.
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 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 to help pro-
vide traction under the tires.
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), release the parking brake
and carefully apply the accelerator to free the vehicle.
Turn off TRC and VSC if these functions are hampering

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 proce-
dure:
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 vehicle 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 pressing
and holding the “ENGINE
START STOP” switch for 3
consecutive seconds or more.
