BASIC FUNCTIONS
10
When your vehicle is receiving signals from
the satellites, the GPSº mark appears at the
top left of the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle posi-
tion on the map display. Tunnels, tall build-
ings, trucks, or even the placement of objects
on the instrument panel may obstruct the
GPS signals.
The installation of window tinting may also ob-
struct the GPS signals. Most window tinting
contains some metallic content that will inter-
fere with the GPS signal reception. We ad-
vice against the use of window tinting on ve-
hicles equipped with navigation systems.
The GPS satellites may not send signals due
to repairs or improvements being made to
them.Even when the navigation system is receiving
clear GPS signals, the vehicle position may
not be shown accurately or inappropriate
route guidance may occur in some cases.
(a) Accurate current vehicle
position may not be shown in
the following cases:

When driving on a small angled Y-shaped
road.

When driving on a winding road.

When driving on a slippery road such as
in sand, gravel, snow, etc.

When driving on a long straight road.

When freeway and surface streets run in
parallel.

After moving by ferry or vehicle carrier.

When a long route is searched during high
speed driving.

When driving without setting the current
position calibration correctly.

After repeating a change of direction by
going forward and backward, or turning on
a turntable in the parking lot.

When leaving a covered parking lot or
parking garage.

When a roof carrier is installed.

When driving with tire chains installed.

When the tires are worn.

After replacing a tire or tires.

When using tires that are smaller or larger
than the factory specifications.

BASIC FUNCTIONS

When the tire pressure in any of the four
tires is not correct.
INFORMATION
If your vehicle cannot receive GPS sig-
nals, you can correct the current posi-
tion manually. For information on set-
ting the current position calibration, see
page 77.
(b) Inappropriate route
guidance may occur in the
following cases:

When turning at an intersection off the
designated route guidance.

If you set more than one destination but
skip any of them, auto reroute will display
a route returning to the destination on the
previous route.

When turning at an intersection, there is
no route guidance.

When passing through the intersection,
there is no route guidance.

During auto reroute, the route guidance
may not be available for the next turn to
the right or left.

It may take a long time to operate auto re-
route during high speed driving. In auto
reroute, a detour route may be shown.

After auto reroute, the route may not be
changed.

An unnecessary U-turn may be shown or
announced.

A location may have multiple names and
the system will announce one or more.

Some routes may not be searched.

If the route to your destination includes
gravel, unpaved roads or alleys, the route
guidance may not be shown.

Your destination point might be shown on
the opposite side of the street.

When a portion of the route has regula-
tions prohibiting the entry of the vehicle
that vary by time or season or other rea-
son.

The road and map data stored in your nav-
igation system may not be complete or
may not be the latest version.
After replacing the tire, implement the op-
eration described in the 
Tire change
calibrationº. (For details, see page 78.)
This navigation system uses the tire turning
data and is designed to work with factory-
specified tires for your vehicle. Installing tires
that are larger or smaller than the originally
equipped diameter may cause inaccurate
display of the vehicle's position. The tire pres-
sure also affects the diameter of the tires so
please make sure the tire pressure of all four
tires is correct.

CAUTION
Do not overestimate the anti- lock
brake system: Although the anti- lock
brake system assists in providing ve-
hicle control, it is still important to
drive with all due care and maintain
a moderate speed and safe distance
from the vehicle in front of you, be-
cause there are limits to the vehicle
stability and effectiveness of steering
wheel operation even with the anti-
lock brake system on.
If tire grip performance exceeds its
capability, or if hydroplaning occurs
during high speed driving in the rain,
the anti- lock brake system does not
provide vehicle control.
Anti- lock brake system is not de-
signed to shorten the stopping dis-
tance: Always drive at the moderate
speed and maintain a safe distance
from the vehicle in front of you.
Compared with vehicles without an
anti- lock brake system, your vehicle
may require a longer stopping dis-
tance in the following cases:

Driving on rough, gravel or snow-
covered roads.

Driving with tire chains installed.

Driving over the steps such as the
joints on the road.

Driving on roads where the road
surface is pitted or has other differ-
ences in surface height.
Install all 4 tires of specified size at
appropriate pressure: The anti- lock
brake system detects vehicle speeds
using the speed sensors for respec-
tive wheels' turning speeds. The use
of tires other than specified may fail
to detect the accurate turning speed
resulting in a longer stopping dis-
tance.

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 gradesÐAll 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 ATreadwearÐThe 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, CÐThe 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.
ÐUniform tire quality grading

'05 HIGHLANDER_U (L/O 0409)
308
2005 HIGHLANDER from Nov. '04 Prod. (OM48570U)
Temperature A, B, CÐT he tem per a-
ture grades are A (the highest), B,
and C, representing the tire's resis-
tance to the generation of heat and
its ability to dissipate heat when
tested under controlled conditions on
a specified indoor laboratory test
wheel. Sustained high temperature
can cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. The grade C cor-
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor Vehicle
Safety Standard No.109. Grades B
and A represent higher levels of per-
formance on the laboratory test wheel
than the minimum required by law.
Warning: The temperature grades for
this tire are established for a tire that
is properly inflated and not over-
loaded. Excessive speed, underinfla-
tion, or excessive loading, either sep-
arately or in combination, can cause
heat buildup and possible tire failure.
