(f) If you cannot shift the selector le-ver out of “P” position
If you cannot shift the selector lever from
the “P” position even though the brake
pedal is depressed, use the shift lock
override button. For instructions, see “If
you cannot shift transmission selector le-
ver” on page 329 in Section 4. Vehicle dynamics integrated manage-
ment (VDIM) is designed to control ve-
hicle motion continuously using all pos-
sible functions to stabilize the motion.
It is important to keep the tires in good
condition for the system to properly
control vehicle motion. Refer to the in-
formation for tires on pages 359
through 367 in Section 72.
The system has the functions listed below.
Each function becomes operational when
the vehicle speed exceeds the speeds as
shown below.
Brake assist function
7km/h(4mph)
Anti−lock brake system function
7km/h(4mph)
Traction control function 0km/h(0mph)
Vehicle stability control function15 km/h (9 mph)
CAUTION
Do not rely excessively on the
VDIM. Even if the system is operat-
ing, you must always drive carefully
and attentively. Reckless driving will
result in an unexpected accident. If
the slip indicator flashes, special
care should be taken.
Only use tires of specified size. The
size, manufacturer, brand and tread
pattern for all 4 tires should be the
same. If you use any tires other
than specified, or different types or
sizes, the VDIM may not function
correctly. When replacing the tires
or wheels, contact your Toyota deal-
er.
Do not modify the suspensions. If
you modify the suspensions, the
VDIM may not function correctly.
In situations where the road surface
is covered with ice or snow, snow
tires or tire chains should be used.

TRACTION CONTROL FUNCTION
The traction control function is designed to
help prevent skid of the drive wheels dur-
ing sudden acceleration on slippery road
surfaces.
You may feel vibration or noise in your
vehicle, caused by operation of the
brakes.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power against drive wheels cannot be
maintained, even though the traction
control system is in operation. Do not
drive the vehicle under any speed or
maneuvering conditions which may
cause the vehicle to lose traction
control. In situations where the road
surface is covered with ice or snow,
your vehicle should be fitted with
snow tires or tire chains. Always
drive at a moderate speed.
VEHICLE STABILITY CONTROL
FUNCTION
The vehicle stability control function is de-
signed to help prevent skid of the wheels
while cornering on slippery road surfaces
or when turning the steering wheel abrupt-
ly.
The system controls the driving and brak-
ing forces on each tire and also controls
the power steering assistance to help the
driver to recover vehicle stability.
CAUTION
Depending on the road conditions,
the vehicle stability control function
may not be able to stabilize your ve-
hicle. Always drive at a moderate
speed.
The tire pressure warning system warns
you that the tire inflation pressure is
low.
The tire pressure warning system is not
a substitute for checking normal tire infla-
tion pressure. Check the tire inflation
pressure with a tire pressure gauge regu-
larly.
CAUTION
The warning system may not activate
immediately if bursts or sudden air
leakage should occur.

This information has been prepared
in accordance with regulations issued
by the National Highway Traffic Safe-
ty Administration of the U.S. Depart-
ment of Transportation. It provides
the purchasers and/or prospective
purchasers of Toyota vehicles with in-
formation on uniform tire quality grad-
ing.
Your Toyota dealer will help answer
any questions you may have as you
read this information.
DOT quality grades—All passenger
vehicle tires must conform to Fed-
eral Safety Requirements in addi-
tion to these grades. Quality
grades can be found where appli-
cable on the tire sidewall between
tread shoulder and maximum sec-
tion width. For example: Treadwear
200 Traction AA Temperature ATreadwear—
The treadwear grade is
a comparative rating based on the
wear rate of the tire when tested un-
der controlled conditions on a speci-
fied government test course. For ex-
ample, a tire graded 150 would wear
one and a half (1 −1/2) times as well
on the government course as a tire
graded 100. The relative performance
of tires depends upon the actual
conditions of their use, however, and
may depart significantly from the
norm due to variations in driving hab-
its, service practices and differences
in road characteristics and climate. Traction AA, A, B, C—
The traction
grades, from highest to lowest, are
AA, A, B, and C, and they represent
the tire’s ability to stop on wet pave-
ment as measured under controlled
conditions on specified government
test surfaces of asphalt and concrete.
A tire marked C may have poor trac-
tion performance.
Warning: The traction grade assigned
to this tire is based on braking
(straight ahead) traction tests and
does not include cornering (turning)
traction.

CAUTION
Even if the total load of occu-
pant’s weight and the cargo load
is less than the total load capac-
ity, do not apply the load uneven-
ly. That may cause not only dam-
age to the tire but also deteriora-
tion to the steering ability due to
unbalance of the vehicle, causing
an accident.
Determine what kind of tires your
vehicle is originally equipped with.1. Summer tires
Summer tires are high −speed capabil-
ity tires best suited to highway driving
under dry conditions.
Since summer tires do not have the
same traction performance as snow
tires, summer tires are inadequate for
driving on snow −covered or icy roads.
For driving on snow −covered or icy
roads, we recommend using snow
tires. If installing snow tires, be sure
to replace all four tires.
2. All season tires
All season tires are designed to pro-
vide better traction in snow and to be
adequate for driving in most winter
conditions, as well as for use all year
round. All season tires, however, do not have
adequate traction performance
compared with snow tires in heavy or
loose snow. Also, all season tires fall
short in acceleration and handling
performance compared with summer
tires in highway driving.
The details about how to distinguish
summer tires from all season tires are
described on page 285.
CAUTION

Do not mix summer and all sea-
son tires on your vehicle as
this can cause dangerous han-
dling characteristics, resulting
in loss of control.
 Do not use tires other than the
manufacturer’s designated
tires, and never mix tires or
wheels of the sizes different
from the originally equipped
tires and wheels.
Types of tires

2007 CAMRY HV from Oct. ’06 Prod. (OM33749U)
See “If you have a flat tire” on page
318 in Section 4 for tire change proce-
dure.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out−
of −balance wheels, or severe braking.
Initial adjustment of the tire pres-
sure warning system is necessary
after you have rotated your tires.
See “Tire pressure warning sys-
tem” on page 168 in Section 17.
CAUTION
Do not include a compact spare
tire when rotating the tires. It is
designed for temporary use only.
WHEN TO USE SNOW TIRES OR
CHAINS
Snow tires or chains are recommended
when driving on snow or ice.
On wet or dry roads, conventional tires
provide better traction than snow tires.
SNOW TIRE SELECTION
If you need snow tires, select tires of
the same size, construction and load
capacity as the originally installed tires.
Do not use tires other than those men-
tioned above. Do not install studded tires
without first checking local regulations for
possible restrictions.
CAUTION
Do not use snow tires other than the
manufacturer ’s recommended size, as
this may cause dangerous handling
characteristics resulting in loss of
control. Otherwise, an accident may
occur resulting in death or serious
injuries.
SNOW TIRE INSTALLATION
Snow tires should be installed on all
wheels.
Installing snow tires on the front wheels
only can lead to an excessive difference
in road grip capability between the front
and rear tires which could cause loss of
vehicle control.
When storing removed tires you should
store them in a cool dry place. Mark the
direction of rotation and be sure to install
them in the same direction when replac-
ing.
CAUTION
Do not drive with the snow tires
incorrectly inflated.
Never drive over 120 km/h (75 mph)
with any type of snow tires.
TIRE CHAIN SELECTION
Use the tire chains of correct size.
