 Wet roads.
 Snowfall.
 Slush.
 Fog.
 Oncoming light.
Pay attention when driving and
respond to the prev ailing traffic con-
ditions. If necessary, intervene
actively, for example by braking,
steering or taking evasive action.
The desired speed is also main-
tained when driving downhill. The
vehicle may drive slower than the
desired speed on uphill gradients if
there is not enough engine power.

Safety note
WA R N I N G
Unsuitable containers placed in the
cupholders may damage the cuphold- ers or be flung into the interior, for
example in the event of an accident or
when braking or carrying out evasive manoeuvres. Spilt liquids can distract
the driver from the road and lead to
an accident. Hot beverages may damage the cupholders or cause
scalding. There is a danger of injury
or damage to property. Do not force objects into the cupholder. Use light-
weight, sealable and shatterproof
containers. Do not transport hot drinks.

Loads
Safety notes
WA R N I N G
A high gross vehicle weight can make
the tyres overheat, causing internal
damage and a sudden loss of tyre inflation pressure. Handling charac-
teristics may be adversely affected,
for example reduced directional sta- bility, longer braking distance and
modified steering characteristics.
There is a risk of accident. Please comply with the permitted load index
of the tyre, and do not exceed the per-
mitted gross vehicle weight.

DRIVING HINTS
When visibility is poor due to fog,
even if it is daytime, turn the low
beam headlights on to make your
vehicle more visible to other vehi-
cles, etc. Drive with caution at a low
speed, using the centerline, guard-
rails, taillights of a preceding vehi-
cle, etc., as guide.
When the vehicle is being blown by
crosswinds, drive at a lower speed
and grip the steering wheel
stronger than normal.
The vehicle is especially suscepti-
ble to crosswinds when exiting a
tunnel or underpass, when driving
on a bridge or embankment, or
when passing or being passed by a
truck or other large vehicle.
 During a rain storm or when the
road surface is wet, the road sur-
face may be slippery and visibil-
ity may be reduced. In this case,
turn the low beam headlights on
to make your vehicle more visi-
ble to other vehicles, etc.
Increase the distance between
your vehicle and preceding vehi-
cles and drive safely at a lower
speed than normal, avoiding
sudden acceleration, braking or
steering operations.
 Use the rear defroster and air
conditioning system to prevent
the windows from fogging 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 tyres
and the road.

DRIVING HINTS
Ensure that you do not obstruct
other road users when doing so.
The heat generated by braking
dries the brake discs and brake
pads and protects them against
corrosion.
This way, brake power is available
immediately, whenever it is needed.
■General
When driving on long or steep
downhill stretches, use the gear in
which the least braking is required.
Otherwise the brake system can
overheat and the braking effect is
reduced.
Engine braking effect can be addi-
tionally increased by manually shift-
ing down, even into first gear, if
applicable.
■Safety notes
Corrosion of the brake discs and
contamination of the brake pads
increase in the following circum-
stances:
 Low mileage.
 Extended periods when the vehi-
cle is not used.
 Infrequent use of the brakes.
 Aggressive, acidic or alkaline
cleaning agents.
During braking, corroded brake
discs may cause brake judder
which usually cannot be eliminated.
When the automatic air condition-
ing is in operation, condensation
develops and exits underneath the
vehicle.
The higher mechanical and thermal
loads involved in driving on racing
tracks lead to increased wear. This
wear is not covered by the war-
ranty. The vehicle is not conceived
for use in motor sports competi-
tions.
Before and after driving on a racing
track, have the vehicle checked at
any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
Downhill gradients
WA R N I N G
Even slight continuous pressure on the brake pedal can cause overheat-
ing, brake pad wear or even brake
system failure. There is a danger of accidents. Avoid excessive loads on
the brake.
WA R N I N G
When idling or with the engine switched off, safety-relevant func-
tions, for example engine braking
effect or steering and braking force assistance, are either restricted or not
available at all. There is a risk of acci-
dent. Do not drive at idle speed or with the engine switched off.

A tyre's condition and inflation pres-
sure influence the following:
• Lifetime of the tyre.
• Driving safety.
• Driving comfort.
• Fuel consumption.
The tyre inflation pressure informa-
tion is located on the body pillar of
the driver's door.
The tyre pressure applies to all tyre
sizes and recommended tyre
makes that have been rated by the
vehicle manufacturer as suitable for
the vehicle type concerned. The list
can also include tyre sizes that are
only suitable in combination with
specific equipment.
Information about approved wheels
and tyres for the vehicle can be

Tyre inflation pressure
General
Safety note
WA R N I N G
A tyre with too little or no tyre inflation
pressure can heat up significantly and sustain damage. Driving properties,
for example steering and braking, will
be impaired as a result. There is a danger of accidents. Check the tyre
inflation pressure regularly and adjust
as necessary, for example twice a
month or before any long journey
Tyre inflation pressure infor-
mation

mation is available from any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
Do not exceed the maximum tyre
inflation pressure indicated on the
tyre's side wall.
• Store wheels and tyres in a cool,
dry and dark place when not in
use.
• Protect the tyres against contam-
ination from oil, grease and sol-
vents.
• Do not leave tyres in plastic
bags.
• Remove dirt from the wheels or
tyres.
In the event of a complete loss of
tyre inflation pressure, run-flat tyres
enable you to continue driving, with
certain restrictions.
The wheels are fitted with tyres
which are self-supporting to a lim-
ited degree. They may also have
special rims.
The reinforced side wall means that
the tyre keeps the vehicle mobile to
a degree even if tyre inflation pres-
sure has been lost.
Observe the notes on continuing to
drive with a flat tyre.
Swapping over front and rear
wheels
WA R N I N G
Swapping over of wheels between
axles on vehicles with different tyre
sizes or rim dimensions on the front and rear axles may cause tyre dam-
age and damage to the vehicle. There
is a risk of accident. Do not swap over wheels between axles on vehicles
with different tyre sizes or rim dimen-
sions on the front and rear axles.

Safety notes
WA R N I N G
A run-flat tyre which has low tyre infla-
tion pressure or no tyre inflation pres- sure at all will change the vehicle's
handling characteristics, for example
there may be reduced directional sta- bility when braking, longer braking
distances and different self-steering
characteristics. There is a danger of accidents. Drive with care and do not
exceed a speed of 80 km/h, 50 mph.

With the Mobility System, minor
tyre damage can be quickly sealed,
to allow you to drive on. For this
purpose, liquid sealant is pumped
into the tyres which encloses the
damage from the inside when it
hardens.
• Please observe the notes on the
application of the Mobility Sys-
tem which are on the compres-
sor and the sealant container.
• Applying the Mobility System can
be ineffective for tyre damage
larger than approximately 4 mm.
• Contact any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer if
you are unable to put the tyre
back in operation.
• Foreign bodies that have pene-
trated the tyre should remain
inside the tyre. Only remove for-
eign objects if they are visibly
protruding from the tyre.
• Remove the speed limit sticker
from the sealant container and
attach to the steering wheel.
• Using sealants can damage the
