other vehicles, etc. Increase
the distance between your
vehicle and preceding vehi-
cles and drive safely at a
lower speed than normal,
avoiding sudden accelera-
tion, braking or steering oper-
ations.
 Use the rear defroster and air
conditioning system to pre-
vent the windows from fog-
ging up.
 Hydroplaning is more likely to
occur when driving on ruts or
through large puddles.
On wet or slushy roads, a
wedge of water can form
between the tires and road sur-
face.
This phenomenon is referred to
as hydroplaning. It is character-
ized by a partial or complete
loss of contact between the tires
and the road surface, ultimately
undermining your ability to steer
and brake the vehicle.
When driving through water, fol-
low the following:
 Deactivate Auto Start/Stop
function.
 Drive through calm water only.
 Drive through water only if it is
not deeper than maximum 9.8
inches/25 cm.
 Drive through water no faster
than walking speed, up to 3
mph/5 km/h.
The vehicle is equipped with an
Antilock Braking System ABS as
a standard feature.
Perform an emergency stop in
situations that require such.
Steering is still responsive. You
can still avoid any obstacles with
a minimum of steering effort.
Pulsation of the brake pedal and
sounds from the hydraulic cir-
cuits indicate that the Antilock
Braking System ABS is in its
active mode.

DRIVING TIPS
 Infrequent use of the brakes.
 Aggressive, acidic, or alka-
line cleaning agents.
Corrosion buildup on the brake
discs will cause a pulsating
effect on the brakes in their
response - generally this cannot
be corrected.
When using the automatic air
conditioning, condensation
water develops and collects
underneath the vehicle.
Higher mechanical and thermal
loads during racetrack operation
lead to increased wear. This
wear is not covered by the war-
ranty. The vehicle is not
designed for use in motor sports
competition.
Have vehicle checked by your
Toyota dealer before and after
driving on a racetrack. This chapter describes all stan-
dard, country-specific and
optional features offered with
the series. It also describes fea-
tures and functions that are not
necessarily available in your
vehicle, e.g., due to the selected
options or country versions. This
also applies to safety-related
functions and systems. When
using these functions and sys-
tems, the applicable laws and
regulations must be observed.
The vehicle contains advanced
technologies for the reduction of
consumption and emission val-
ues.
Fuel consumption depends on a
number of different factors.
Carrying out certain measures,
such as a moderate driving style
and regular maintenance, can
influence fuel consumption and
the environmental impact.

vehicle roll.
The flow of fuel is interrupted
while coasting.
Switch off the engine during lon-
ger stops, for instance at traffic
lights, railroad crossings or in
traffic congestion.
The Auto Start/Stop function of
the vehicle automatically
switches off the engine during a
stop.
If the engine is switched off and
then restarted rather than leav-
ing the engine running con-
stantly, fuel consumption and
emissions are reduced. Sav-
ings can begin within a few sec-
onds of switching off the engine.
In addition, fuel consumption is
also determined by other fac-
tors, such as driving style, road
conditions, maintenance or envi-
ronmental factors.
Functions such as seat heating
and the rear window defroster require a lot of energy and
increase fuel consumption,
especially in city and
stop-and-go traffic.
Switch off these functions if they
are not needed.
Have the vehicle maintained
regularly to achieve optimal
vehicle efficiency and service
life. Toyota recommends that
maintenance work be performed
by Toyota.

Depending on the region, many
gas stations sell fuel that has
been customized to winter or
summer conditions. Fuel that is
available in winter,for instance
helps make a cold start easier.
For the best fuel efficiency, the
gasoline should be sulfur-free or
very low in sulfur content.
Fuels that are marked on the
gas pump as containing metal must not be used.
Fuels with a maximum ethanol
content of 25 %, i. e. E10 or
E25, may be used for refueling.
Ethanol should meet the follow-
ing quality standards:
US: ASTM 4806–xx
CAN: CGSB-3.511–xx

The use of poor-quality fuels may
result in harmful engine deposits
or damage. Additionally, problems
relating to drivability, starting and
stalling, especially under certain
environmental conditions such as
high ambient temperature and
high altitude, may occur.
If drivability prob lems are encoun-
tered, we recommend switching
to a high quality gasoline brand
and a higher octa ne grade - AKI
number - for a few tank fills. To
avoid harmful engi ne deposits, it
is highly recommended to pur-
chase gasoline from Top Tier
retailers.
Failure to comply with these rec-
ommendations may result in the
need for unscheduled mainte-
nance.

All passenger vehicle tires must
conform to Federal Safety
Requirements in addition to
these grades
The treadwear grade is a com-
parative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test
course. E.g., a tire graded 150
would wear one and one-half, 1
g, times as well on the govern-
ment 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 habits, service prac-
tices and differences in road
characteristics and climate.
The traction grades, from high-
est to lowest, are AA, A, B, and
C.
Those grades represent the
tire's ability to stop on wet pave-
ment as measured under con-
trolled conditions on specified
government test surfaces of
asphalt and concrete. A tire
marked C may have poor trac-tion performance.
The traction grade assigned to
this tire is based on
straight-ahead braking traction
tests, and does not include
acceleration, cornering, hydro-
planing, or peak traction charac-
teristics.
The temperature grades are A,
the highest, B, and C, represent-
ing the tire's resistance 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 tempera-
ture 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 corresponds to a
level of performance which all
passenger vehicle tires must
meet under the Federal Motor
Vehicle Safety Standard No.
109. Grades Band A represent
higher levels of performance on
the laboratory test wheel than
the minimum required by law.

Winter and all-season tires with
better cold weather performance
than summer tires.
Do not drive with a tire tread of
less than 0.12 in/3 mm, other-
wise there is an increased risk
of hydroplaning.
Do not drive with a tire tread of
less than 0.16 in/4 mm, as such
tires are less suitable for winter
operation. Wear indicators are distributed
around the tire's circumference
and have the legally required
minimum height of 0.063
inches/1.6 mm.
The positions of the wear indica-
tors are marked on the tire side-
wall with TWI, Tread Wear
Indicator.
Inspect your tires regularly for
damage, foreign objects lodged
in the tread, and tread wear.
Driving over rough or damaged
road surfaces, as well as debris,
curbs and other obstacles can
cause serious damage to
wheels, tires and suspension
parts. This is more likely to
occur with low-profile tires,
which provide less cushioning
between the wheel and the
road. Be careful to avoid road
hazards and reduce your speed,
especially if your vehicle is
WA R N I N G
The temperature grade for this tire
is established for a tire that is
properly inflated and not over-
loaded. Excessive speed, under-
inflation, or excessive loading,
either separately or in combina-
tion, can cause heat buildup and
possible tire failure.

For each tire size, the manufac-
turer of the vehicle recommends
certain tire brands. The tire
brands can be identified by a
star on the tire sidewall.
Tire traction is not optimal due to
manufacturing circumstances
when tires are brand-new; they
achieve their full traction poten-
tial after a break-in time.
Drive conservatively for the first
200 miles/300 km.
The manufacturer of your vehi-
cle does not recommend the
use of retreaded tires.
Safety information
WA R N I N G
Wheels and tires which are not
suitable for your
vehicle can dam-
age parts of the vehicle, for
instance due to contact with the
body due to tolerances despite
the same official size rating.
There is a risk of an accident. The
manufacturer of your vehicle
strongly suggests that you use
wheels and tires that have been
recommended by the vehicle
manufacturer for your vehicle
type.
WA R N I N G
Mounted steel wheels can cause
technical problem s, for instance
unexpected loosening of the lug
bolts and damage to the brake
discs. There is a risk of accident.
Do not mount steel wheels.
WA R N I N G
Incorrect wheel/tire combinations
will have a negative impact on the
vehicle's handling and on the
function of a variety of systems,
such as the Anti-lock Brake Sys-
tem or Vehicle S tability Control
System. There is a risk of an acci-
dent. To maintain good handling
and vehicle response, use only
tires with a single tread configura-
tion from a single manufacturer.
The manufacturer of the vehicle
recommends that you use wheels
and tires that have been recom-
mended by the vehicle manufac-
turer for your vehicle type.
Following tire damage, have the
original wheel/tire combination
remounted on the vehicle as soon
as possible.
