WARNING
■Replacing light bulbs
●Turn off the lights. Do not attempt to
replace the bulb immediately after turning off the lights. The bulbs become very hot and may cause
burns.
●Do not touch the glass portion of
the light bulb with bare hands. When it is unavoidable to hold the glass portion, use and hold with a
clean dry cloth to avoid getting moisture and oils on the bulb. Also, if the bulb is scratched or dropped,
it may blow out or crack.
●Fully install light bulbs and any
parts used to secure them. Failure to do so may result in heat damage, fire, or water entering the light unit.
This may damage the lights or cause condensation to build up on the lens.
■To prevent damage or fire
Make sure bulbs are fully seated and
locked.

7-1. Essential information
When trouble arises
Vehicles with a smart entry &
start system
Press and hold the engine switch for 2
consecutive seconds or more, or press
it briefly 3 times or more in succession.
5 Stop the vehicle in a safe place
by the road.
z Remove the seat belt first.
z If the door can be opened, open
the door and exit the vehicle.
z If the door cannot be opened,
open the window using the
power window switch and exit
the vehicle through the window.
z If the window cannot be opened
using the power window switch,
remain calm, wait until the water
level inside the vehicle rises to
the point that the water pressure
inside of the vehicle equals the
water pressure outside of the
vehicle, and then open the door
and exit the vehicle.
WARNING
■If the engine has to be turned off while driving
●Power 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 possi- ble before turning off the engine.
●Vehicles without a smart entry & start system: Never attempt to remove the key, as doing so will
lock the steering wheel.
If the vehicle is trapped
in rising water
In the event the vehicle is sub-
merged in water, remain calm
and perform the following.
WARNING
■Using an emergency hammer* for
emergency escape
The front side windows and rear side windows, as well as the rear window
can be shattered with an emergency
hammer* used for emergency escape. However, an emergency
hammer* cannot shatter the wind- shield as it is laminated glass.*: Contact any authorized Toyota

When trouble arises
7-2.Ste ps to take in an emerg ency
If your vehicle needs to
be towed
If towing is necessary, we rec-
ommend having your vehicle
towed by any authorized
Toyota retailer or Toyota autho-
rized repairer, or any reliable
repairer or commercial towing
service, using a wheel-lift type
truck or flatbed truck.
Use a safety chain system for
all towing, and abide by all
state/provincial and local laws.
WARNING
Observe the following precautions. Failure to do so may result in death or serious injury.
■When towing the vehicle
Be sure to transport the vehicle with
the front wheels raised or with all four wheels raised off the ground. If the vehicle is towed with the front wheels
contacting the ground, the drivetrain and related parts may be damaged.
■While towing
●When towing using cables or chains, avoid sudden starts, etc.
which place excessive stress on the towing eyelets, cables or chains. The towing eyelets, cables or
chains may become damaged, bro- ken debris may hit people, and cause serious damage.
●Do not turn the engine switch off.There is a possibility that the steer-
ing wheel is locked and cannot be operated.
■Installing towing eyelets to the vehicle
Make sure that towing eyelets are
installed securely. If not securely installed, towing eye-lets may come loose during towing.
NOTICE
■To prevent damage to the vehicle when towing using a wheel-lift type truck
●Do not tow the vehicle from the rear when the engine switch is off. The steering lock mechanism is not
strong enough to hold the front wheels straight.
●When raising the vehicle, ensure adequate ground clearance for tow-ing at the opposite end of the raised
vehicle. Without adequate clear- ance, the vehicle could be dam-aged while being towed.
■To prevent damage to the vehicle when towing with a sling-type
truck
Do not tow with a sling-type truck, either from the front or rear.
■To prevent damage to the vehicle during emergency towing
Do not secure cables or chains to the suspension components.

7-2. Steps to take in an emergency
When trouble arises
If a tow truck is not available in an
emergency, your vehicle may be
temporarily towed using cables or
chains secured to the emergency
towing eyelets. This should only be
attempted on hard surfaced roads
for at most 80 km (50 miles) at
under 30 km/h (18 mph).
A driver must be in the vehicle to
steer and operate the brakes. The
vehicle’s wheels, drive train, axles,
steering and brakes must be in
good condition.
For vehicles with a Multidrive, only
the front towing eyelets may be
used.
To have your vehicle towed by
another vehicle, the towing eyelet
must be installed to your vehicle.
Install the towing eyelet using the
following procedure.
1 Take out the wheel nut wrench,
flathead screwdriver and towing
eyelet. ( →P.390)
2 Remove the eyelet cover using
a flathead screwdriver.
To protect the bodywork, place a rag
between the screwdriver and the vehi- cle body as shown in the illustration.
3 Insert the towing eyelet into the
hole and tighten partially by
hand.

that the sealant is injected.
■If the tire is inflated to more than the specified air pressure
1 Press the button to let some air out.
2 Check that the air pressure indicator shows the specified air pressure. If
the air pressure is under the desig- nated pressure, turn the compres-sor switch on again and repeat the
inflation procedure until the specified air pressure is reached.
■The valve of a tire that has been repaired
After a tire is repaired with the emer- gency tire puncture repair kit, the valve should be replaced.
■After a tire is repaired with the
emergency tire puncture repair kit
●The tire pressure warning valve and
transmitter should be replaced.
●Even if the tire inflation pressure is at the recommended level, the tire pres-sure warning light may come on/flash.
WARNING
■Do not drive the vehicle with 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 cir- cumferential groove on the side wall. In such a case, the tire may explode
when using a repair kit.
■When fixing the flat tire
●Stop your vehicle in a safe and flat area.
●Do not touch the wheels or the area around the brakes immediately
after the vehicle has been driven. After the vehicle has been driven, the wheels and the area around the
brakes may be extremely hot. Touching these areas with hands, feet or other body parts may result
in burns.
●Connect the valve and hose
securely with the tire installed on the vehicle. If the hose is not prop-erly connected to the valve, air
leakage may occur as sealant may be sprayed out.
●If the hose comes off the valve while inflating the tire, there is a risk that the hose will move abruptly due
to air pressure.
●After inflation of the tire has com-
pleted, the sealant may splatter when the hose is disconnected or some air is let out of the tire.
●Follow the operation procedure to repair the tire. If the procedures not
followed, the sealant may spray out.
●Keep back from the tire while it is being repaired, as there is a chance of it bursting while the repair opera-
tion is being performed. If you notice any cracks or deformation of the tire, turn off the compressor
switch and stop the repair operation immediately.
●The repair kit may overheat if oper-ated for a long period of time. Do not operate the repair kit continu-
ously for more than 40 minutes.
