Driving
WARNING
■Pre-collision braking
●When the pre-collision braking function is operating, a large amount of
braking force will be applied.
●If the vehicle is stopped by the operation of the pre-collision braking func-
tion, the pre-collision braking function operation will be canceled after
approximately 2 seconds. Depress the brake pedal as necessary.
●The pre-collision braking function may not operate if certain operations are
performed by the driver. If the accelerator pedal is being depressed
strongly or the steering wheel is being turned, the system may determine
that the driver is taking evasive action and possibly prevent the pre-colli-
sion braking function from operating.
●In some situations, while the pre-collision braking function is operating,
operation of the function may be canceled if the accelerator pedal is
depressed strongly or the steering wheel is turned and the system deter-
mines that the driver is taking evasive action.
●If the brake pedal is being depressed, the system may determine that the
driver is taking evasive action and possibly delay the operation timing of
the pre-collision braking function.
■Emergency steering assist
●As emergency steering assist operation will be canceled when the system
determines that lane departure prevention function has been completed.
●Emergency steering assist may not operate or may be cancel in the follow-
ing cases as the system may determine the driver is taking actions.
• If the accelerator pedal is being depressed strongly, the steering wheel
is being operated sharply, the brake pedal is being depressed or the
turn signal lever is being operated. In this case, the system may deter-
mine that the driver is taking evasive action and the emergency steering
assist may not operate.
• In some situations, while the emergency steering assist is operating,
operation of the function may be canceled if the accelerator pedal is
depressed strongly, the steering wheel is operated sharply or the brake
pedal is being depressed and the system determines that the driver is
taking evasive action.
• When the emergency steering assist is operating, if the steering wheel
is held firmly or is operated in the opposite direction to that which the
system is generating torque, the function may be canceled.

When trouble arises
When replacing tires on a vehicle with wheel lock nuts, use the follow-
ing procedures to remove and install the wheel lock nuts. The wheel
lock key is stored in the tray inside the luggage compartment. Always
return the wheel lock key to its original position after use, so that it
does not get lost. (P. 513)
■Removal
For ease of removal, the wheel lock nut should always be the first
one loosened.
Place the wheel lock key on top of the wheel lock nut, turning
until the wheel lock key and wheel lock nut patterns engage.
Place the wheel nut wrench on the wheel lock key, and while
applying pressure on the wheel lock key, loosen the wheel lock
nut.
■Installation
For ease of installation, the wheel lock nut should always be the
last one tightened.
By hand, install a wheel lock nut on the wheel to be installed.
Place the wheel lock key on top of the wheel lock nut, turning
until the wheel lock key and wheel lock nut patterns engage.
Place the wheel nut wrench on the wheel lock key, and while
applying pressure on the wheel lock key, tighten the wheel lock
nut to the recommended torque.
Wheel lock nut (if equipped)
NOTICE
■When using a wheel lock key
Do not use an impact wrench. Using an impact wrench may cause perma-
nent damage to wheel lock nut and wheel lock key. If in doubt about wheel
lock application, contact your Toyota dealer.

WARNING
■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 possible after changing wheels.
• Do not attach a heavily damaged wheel ornament, as it may fly off
the wheel while the vehicle is moving.
• 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 wheel, have the vehicle inspected by
your Toyota dealer.
• When installing the wheel nuts, be sure to install them with the
tapered ends facing inward.
5227-2. Steps to take in an emergency
Firmly tighten each wheel nut
two or three times in the order
shown in the illustration.
Vehicles with wheel locks:
Tighten the wheel lock using the
wheel lock key after tightening
the other wheel nuts.
Tightening torque:
76 ft•lbf (103 N•m, 10.5 kgf•m)
Stow the flat tire, tire jack and all tools.
■The compact spare tire
●The compact spare tire is identified by the label “TEMPORARY USE
ONLY” on the tire sidewall.
Use the compact spare tire temporarily, and only in an emergency.
●Make sure to check the tire inflation pressure of the compact spare tire.
(P. 5 5 0 )
■When using the compact spare tire
As the compact spare tire is not equipped with a tire pressure warning
valve and transmitter, low inflation pressure of the spare tire will not be
indicated by the tire pressure warning system. Also, if you replace the
compact spare tire after the tire pressure warning light comes on, the light
remains on.
■When the compact spare tire is equipped
When driving with the compact spare tire installed, the vehicle height will
be different than when driving with standard tires.
■If you have a flat front tire on a road covered with snow or ice (vehi-
cles with 16 or 17-inch wheels)
Install the compact spare tire on one of the rear wheels of the vehicle.
Perform the following steps and fit tire chains to the front tires:
Replace a rear tire with the compact spare tire.
Replace the flat front tire with the tire removed from the rear of the vehi-
cle.
Fit tire chains to the front tires.
