7-2. Steps to take in an emergency
When trouble arises
■If “Check Owner’s Manual” is dis-
played
●If the following messages are shown,
following the instructions, accordingly. • “High Coolant Temperature” ( P.362)
• “Transmission Oil Temperature”
( P.143)
●If any of the following messages are
shown on the multi-information dis- play, it may indicate a malfunction.
Have the vehicle inspected by any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer immediately.
• “EyeSight OFF” • “Headlights Disabled”
• “ABS”
• “Steering System” • “Vehicle Stability Control”
• “Transmission”
• “Low Tire Pressure” • “RAB Disabled”
• “BSD/RCTA Disabled”
• “Keyless Access System Disabled” • “Auto Headlight Leveler Disabled”
• “SRH Disabled”
• “Gasoline Particulate Filter”
●If any of the following messages are
shown on the multi-information dis- play, it may indicate a malfunction.
Immediately stop the vehicle and con-
tact any authorized Toyota retailer or Toyota authorized repairer, or any reli-
able repairer.
• “Brake System” • “Check Engine”
• “SRS Airbag System”
 Stop the vehicle in a safe place
on a hard, flat surface.
 Set the parking brake.
 Shift the shift lever to P (auto-
matic transmission) or R (manual
transmission).
 Stop the engine.
 Turn on the emergency flashers.
( P.326)
 Check the degree of the tire
damage.
A tire should only be repaired with
the emergency tire puncture repair
If you have a flat tire
Your vehicle is not equipped
with a spare tire, but instead is
equipped with an emergency
tire puncture repair kit.
A puncture caused by a nail or
screw passing through the tire
tread can be repaired tempo-
rarily with the emergency tire
puncture repair kit.
WA R N I N G
■If you have a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the
wheel beyond repair. Driving with a
flat tire may cause a circumferential groove on the side wall. In such a
case, the tire may explode when
using the emergency tire puncture repair kit, resulting in death or serious
injury.
Before repairing the vehicle

3627-2. Steps to take in an emergency
1Stop the vehicle in a safe place
and turn off the air conditioning
system, and then stop the
engine.
2 If you see steam: Carefully lift
the hood after the steam sub-
sides.
If you do not see steam: Care-
fully lift the hood.
3 After the engine has cooled
down sufficiently, inspect the
WA R N I N G
●In the event that battery fluid comes
into contact with the skin or eyes,
immediately wash the affected area with water and seek medical atten-
tion. Place a wet sponge or cloth
over the affected area until medical attention can be received.
●Always wash your hands after han-
dling the battery support, terminals, and other battery-related parts.
●Do not allow children near the bat-tery.
■To prevent damage to the vehicle
Do not pull- or push-start the vehicle
as the three-way catalytic converter
may overheat and become a fire haz- ard.
NOTICE
■When handling jumper cables
Be careful that the jumper cables do
not become tangled in the cooling fans or any of the belts when connect-
ing or disconnecting them.
■When closing the doors
While pushing the door glass towards
the inside of the vehicle, slowly close the door.
Because the side window open/close
function linked to door operation will not operate, the window may interfere
with the vehicle body, possibly
scratching both the vehicle body and window, or even shattering the win-
dow.
If your vehicle overheats
The following may indicate that
your vehicle is overheating.
 The engine coolant tempera-
ture gauge ( P.88) is in the
red zone or a loss of engine
power is experienced. (For
example, the vehicle speed
does not increase.)
 “High Coolant Temperature
Check Owner's Manual” is
shown on the multi-information
display.
 Steam comes out from under
the hood.

7-2. Steps to take in an emergency
When trouble arises
hoses and radiator core (radia-
tor) for any leaks.
Radiators
Cooling fans
If a large amount of coolant leaks,
immediately contact any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
4 The coolant level is satisfactory
if it is between the “FULL” and
“LOW” lines on the reservoir.
Reservoir
“FULL” line
“LOW” line
Radiator cap
5 Add engine coolant if necessary.
Water can be used in an emergency if
engine coolant is unavailable.
6 Start the engine and turn the air
conditioning system on to check
that the radiator cooling fans
operate and to check for coolant
leaks from the radiator or hoses.
The fans operate when the air condi-
tioning system is turned on immediately
after a cold start. Confirm that the fans are operating by checking the fan
sound and air flow. If it is difficult to
check these, turn the air conditioning system on and off repea tedly. (The fans
may not operate in freezing tempera-
tures.)
7 If the fans are not operating:
Stop the engine immediately
and contact any authorized
Toyota retailer or Toyota author-
ized repairer, or any reliable
repairer.
If the fans are operating: Have
the vehicle inspected at the
nearest any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.

■When inspecting under the hood
of your vehicle
Observe the following precautions. Failure to do so ma y result in serious
injury such as burns.

3647-2. Steps to take in an emergency
1Stop the engine. Set the parking
brake and shift the shift lever to
P (automatic transmission) or N
(manual transmission).
2 Remove the mud, snow or sand
from around the rear wheels.
3 Place wood, stones or some
other material under the rear
wheels to help provide traction.
4 Restart the engine.
5 Shift the shift lever to D or R
(automatic transmission) or 1 or
R (manual transmission) and
release the parking brake. Then,
while exercising caution,
depress the accelerator pedal.
■When it is difficult to free the vehi- cle
Press the switch to turn off TRC.
WA R N I N G
●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 (espe-
cially a tie, a scarf or a muffler)
away from the fans and belts. Fail-
ure to do so may cause the hands or clothing to be caught, resulting in
serious injury.
●Do not loosen the coolant reservoir
caps while the engine and radiator
are hot. High temperature steam or coolant
could spray out.
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 additive.
If the vehicle becomes
stuck
Carry out the following proce-
dures if the tires spin or the
vehicle becomes stuck in mud,
dirt or snow:
