General driving notes
Closing the trunk lid
Safety information
WARNING
An open trunk lid protrudes from
the vehicle and can endanger
occupants and other traffic partici-
pants or damage the vehicle in
the event of an a ccident, braking
or evasive maneu vers. In addi-
tion, exhaust fumes may enter the
car's interior. There is a risk of
injury or risk of damage to prop-
erty. Do not drive with the trunk lid
open.
Ice on window glass
NOTICE
The window will be lowered
slightly when pulling on the door
handle. In the eve nt of frost, the
window may freeze up and not be
lowered. There is a risk of dam-
age to property. When pulling on
the door handle, make sure that
the window is lowered. If neces-
sary, remove snow and ice from
the window. Do not open the door
with force.
Hot exhaust gas system
WARNING
High temperatures can occur
underneath the body, for instance
caused by the exhaust gas sys-
tem, while driving. Contact with
the exhaust gas system can
cause burns. The re is a risk of
injury. Do not touch the hot
exhaust gas system, including the
exhaust pipe.
WARNING
If combustible materials, such as
leaves or grass, come in contact
with hot parts of the exhaust gas
system, these materials can
ignite. There is a risk of fire and
injuries. Do not r emove the heat
shields installed and never apply
undercoating to them. Make sure
that no combustible materials can
come in contact with hot vehicle
parts in driving operation, idle or
during parking.

DRIVING TIPS
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 through water
General information
Safety information
NOTICE
When driving too quickly through
too deep water, water can enter
into the engine compartment, the
electrical system or the transmis-
sion. There is a risk of damage to
property. When driving through
water, do not exc eed the maxi-
mum indicated water level and the
maximum speed for driving
through water.
Braking safely
General information

2624-1. DRIVING TIPS
perforated brake discs can emit
functional noises. However,
functional noises have no effect
on the performance and opera-
tional reliability of the brake.
When roads are wet, salted, or
in heavy rain, gently press the
brake pedal every few miles.
Ensure that this action does not
endanger other traffic.
The heat generated during brak-
ing dries brake discs and brake
pads and protects them against
corrosion.
In this way braking efficiency will
be available when you need it.
■General information
Drive long or steep downhill gra-
dients in the gear that requires
least braking effort. Otherwise,
the brakes may overheat and
reduce brake efficiency.
You can increase the engine's
braking effect by shifting down,
going all the way to first gear, if
needed.
■Safety information
Corrosion on the brake discs
and contamination on the brake
pads are increased by the fol-
lowing circumstances:
 Low mileage.
 Extended periods when the
vehicle is not used at all.
Objects in the area around
the pedals
WARNING
Objects in the dri
ver's floor area
can limit the peda l distance or
block a depressed pedal. There is
a risk of an accident. Stow objects
in the vehicle such that they are
secured and cannot enter into the
driver's floor area. Use floor mats
that are suitable for the vehicle
and can be safely attached to the
floor. Do not use loose floor mats
and do not layer several floor
mats. Make sure that there is suf-
ficient clearance for the pedals.
Ensure that the floor mats are
securely fastened again after they
were removed, fo r instance for
cleaning.
Driving in wet conditions
Hills
WARNING
Light but consis tent brake pres-
sure can lead to high tempera-
tures, brakes wearing out and
possibly even brake failure. There
is a risk of an accident. Avoid
placing excessive stress on the
brake system.
WARNING
In idle state or with the engine
switched off, safety functions, for
instance engine braking effect,
braking assistance and steering
assistance, may not be available.
There is a risk of accident. Do not
attempt to drive in idle state or
with the engine switched off.
Brake disc corrosion

2634-1. DRIVING TIPS
4
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.
The fuel consumption depends
on various factors, such as driv-
ing style, road conditions, main-
tenance or environmental
factors.
Carrying out certain measures,
such as a moderate driving style
and regular maintenance, can
influence fuel consumption and
the environmental impact.

2805-1. MOBILITY
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.
Safety information
WARNING
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.
WARNING
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.
WARNING
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.
Recommended tire brands
New tires
Retreaded tires
WARNING
Retreaded tires can have different
tire casing structures. With
advanced age the service life can
be limited. There is a risk of acci-
dent. The manufacturer of the
vehicle does not recommend the
use of retreaded tires.
