CAUTION
■Replacing a flat tire
●Do not touch the disc wheels or the area around the brakes immedi-
ately after the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around
the brakes will be extremely hot.
Touching these areas with hands, feet
or other body parts while changing a tire, etc. may result in burns.
●Failure to follow these precautions could cause the wheel nuts to
loosen and the tire to fall off, resulting in death or serious injury.
• Have the wheel nuts tightened with a torque wrench to 76 ft·lbf (103 N·m, 10.5 kgf·m) as soon as po ssible after changing wheels.
• When installing a tire, only use wheel nuts that have been specifi- cally designed for that wheel.
• If there are any cracks or deformations in the bolt screws, nut threads or bolt holes of the wh eel, have the vehicle inspected by
your Toyota dealer.
• When installing the wheel nuts, be sure to install them with the
tapered ends facing inward. ( →P. 266)
■When stowing the flat tire
●Make sure the rear seats are in their original position.
● Secure it using a tire tie-down belt. Otherwise, the flat tire may fly out in
case of the sudden braking or an accident, resulting in death or serious
injury.

If the shift lever cannot be shifted from P (vehicles with an automatic transmission)
If the shift lever cannot be shifted with your foot on the brake pedal,
there may be a problem with the shift lock system (a system to pre-
vent accidental operation of the shift lever). Have the vehicle
inspected by your Toyo ta dealer immediately.
The following steps may be used as an emergency measure to
ensure that the shift lever can be shifted:
Set the parking brake.
Turn the engine switch to the “ACC” position.
Depress the brake pedal.
Pry the cover up with a flat-
head screwdriver or equiva-
lent tool.
To prevent damage to the
cover, cover the tip of the
screwdriver with a rag.
Press the shift lock override
button.
The shift lever can be shifted
while the button is pressed.

If the vehicle becomes stuck
■Emergency 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 parki ng 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 under the tires
to help provide traction.
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) and carefully apply the accelerator to
free the vehicle.
Turn off TRAC and VSC if these functions are hampering your
attempts to free the vehicle. ( →P. 163)
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.

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 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.
Stop the vehicle in a safe place by the road.

CAUTION
■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 possible before turning off the engine.
● Never attempt to remove the key, as doing so will lock the steering wheel.
