ating an air cushion to help
reduce the impact on the occu-
pants and restrain them from
contacting the door window,
door, etc. with their head and
torso. When an airbag deploys,
as it will inflate nearly instantly, it
may impact an occupant and
cause an injury, or the loud
noise emitted by ignition or
deployment may cause tempo-
rary partial loss of hearing. Also,
as an airbag and nearby parts
will be extremely hot after the
airbag deploys, touching them
may cause burns. For these rea-
sons, deployment of the airbags
is not entirely risk free. There-
fore, in order to reduce this risk,
the airbags are designed to only
deploy when additional reduc-
tion of the impact applied to the
occupants in a collision is nec-
essary.
If the force of the collision does
not cause the airbags to deploy,
the seatbelts will protect the
occupants.
WARNING
Do not install seat covers which
are not designed for use with this
vehicle, or attach a cushion or any
other accessory to either front
seat or hang anything on either
front seatback. Do not place
objects around the side of either
front seat. Refer to P.164for the
installation position of the SRS
side airbags.
WARNING
Do not lean against the door or
door window.
Also, do not install a cup holder or
any other accessor ies near the
SRS side airbags.
If anything is attached to or left in
the deployment a rea of an SRS
side airbag, the airbag may be
prevented from deploying or the
object may become a projectile
when the airbag deploys, possibly
leading to injury. Also, if an occu-
pant is leaning into this area, the
airbag may strike and injure the
head or arm of the occupant when
deploying.
WARNING
When using a cup holder, use the
use the existing cup holders in the
vehicle. Do not place anything but
appropriately sized containers
into the cup holders. Refrain from
placing hot drinks or glass con-
tainers in the cup holders as they
may cause burns or other injuries
in the event of a collision or sud-
den braking.

2644-1. DRIVING TIPS
Additional weight increases fuel
consumption.
Attached parts on the vehicle
impair the aerodynamics and
increase the fuel consumption.
Open windows increase air
resistance and therefore lead to
greater fuel consumption.
Tires can affect consumption in
various ways, for instance tire
size may influence consump-
tion.
Check and, if needed, correct
the tire inflation pressure at least
twice a month and before start-
ing on a long trip.
Low tire inflation pressure
increases rolling resistance and
thus raises fuel consumption
and tire wear.Do not wait for the engine to
warm-up while the vehicle
remains stationary. Start driving
right away, but at moderate
engine speeds.
This is the quickest way of
warming the cold engine up to
operating temperature.
Driving smoothly and proactively
reduces fuel consumption.
Avoid unnecessary acceleration
and braking.
By maintaining a suitable dis-
tance to the vehicle driving
ahead of you.
Driving at low engine speeds
lowers fuel consumption and
reduces wear.
If necessary, observe the vehi-
cle's gear shift indicator, refer to
page 148.
When approaching a red light,
take your foot off the accelerator
and let the vehicle coast to a
halt.
For going downhill take your foot
off the accelerator and let the

WARNING
A tire with too little or no tire infla-
tion pressure may heat up signifi-
cantly and sustain damage. This
will have a negative impact on
aspects of handling, such as
steering and braking response.
There is a risk of an accident.
Regularly check the tire inflation
pressure, and correct it as
needed, for instance twice a
month and before a long trip.

The current tire inflation pres-
sure values and the intended
tire inflation pressure values for
the mounted tires can be dis-
played on the Control Display.
To ensure that they are dis-
played correctly, the tire sizes
must be stored in the system
and must have been set, refer to
page 287, for the mounted tires.
The current tire inflation pres-
sure value is located on each
tire.
The reference tire inflation pres-
sure value is located in the
lower area of the Control Dis-
play.
Tires heat up while driving. The
tire inflation pressure increases
with the tire temperature.
Tires have a natural, consistent
loss of tire inflation pressure.
The displays of inflation devices
may under-read by up to 0.1
bar/2 psi.The tire inflation pressure speci-
fications in the tire inflation pres-
sure table only relate to cold
tires or tires at the same tem-
perature as the ambient tem-
perature.
Only check the tire inflation
pressure levels when the tires
are cold, i.e.:
• Driving range of max. 1.25
miles/2 km has not been
exceeded.
• If the vehicle has not moved again for at least 2 hours after
a trip.
Check the tire inflation pressure
of the emergency wheel in the
cargo area regularly, and correct
it as needed.
1 Determine, refer to page 270,
the intended tire inflation
pressure levels for the
mounted tires.
2 Check the tire inflation pres-
sure in all four tires, using a
pressure gauge, for example.
3 Correct the tire inflation pres-
sure if the actual tire inflation
pressure deviates from spec-
ified tire inflation pressure.
4 Check whether all valve caps
are screwed onto the tire
valves.

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
equipped with low-profile tires.
Indications of tire damage or
other vehicle malfunctions:
• Unusual vibrations.
• Unusual tire or running noises.
• Unusual handling such as a strong tendency to pull to the
left or right.
• Uneven wear pattern, e.g., increased wear in the area of
the tire shoulder.
Damage can be caused by the
following situations, for instance:
• Driving over curbs.
• Road damage.
• Tire inflation pressure too low.
• Vehicle overloading.
• Incorrect tire storage. Have mounting and wheel bal-
ancing carried out by your Toy-
ota dealer.
The following properties are rec-
ommended and approved by the
manufacturer of the vehicle for
the approved wheels and tires
per vehicle type and special
equipment:
• Wheel and tire combinations.
• Rim designs.
• Tire sizes.
• Tire brands.
You can ask your Toyota dealer
about the approved wheels and
tires for the vehicle and the spe-
cial equipment.
Safety information
WARNING
Damaged tires can lose tire infla-
tion pressure, which can lead to
loss of vehicle control. There is a
risk of an accident. If tire damage
is suspected while driving, imme-
diately reduce speed and stop.
Have wheels and tires checked.
For this purpose, drive carefully to
the nearest your Toyota dealer.
Have vehicle towed or trans-
ported as needed. Do not repair
damaged tires, but have them
replaced.
WARNING
Tires can become damaged by
driving over obstacles, e.g., curbs
or road damage, at high speed.
Larger wheels have a smaller tire
crosssection. The smaller the tire
cross-section, the
higher the risk
of tire damage. There is a danger
of accidents and property dam-
age. If possible, avoid driving over
objects or road conditions that
may damage tires, or drive over
them slowly and carefully.

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.

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.

Winter tires are recommended
for operating on winter roads.
Winter tires can be identified by
the symbol with mountain and
snowflake, as well as the M+S
marking on the tire sidewall.
So-called all-season tires with
M+S designation, but without
symbol with mountain and
snowflake, have better winter
characteristics than summer
tires but generally do not
achieve the performance of win-
ter tires.
If the maximum speed of the
vehicle is higher than the per-
missible speed for the winter
tires, then attach a label show-
ing the permissible maximum
speed in the field of view. The
label is available from your Toy-
ota dealer.
With winter tires mounted, observe and do not exceed the
permissible maximum speed.
Do not exceed the maximum tire
inflation pressure indicated on
the side wall of the tire.
Store wheels and tires in a cool,
dry and dark place.
Always protect tires against all
contact with oil, grease, and sol-
vents.
Do not leave tires in plastic
bags.
Remove dirt from wheels or
tires.
