• Tire Pressure Monitor mal- function: have the system
checked by your Toyota
dealer.
• Each tire, including the spare (if provided) should be
checked monthly when cold
and inflated to the inflation
pressure recommended by
the vehicle manufacturer on
the vehicle placard or tire
inflation pressure label. (If
your vehicle has tires of a dif-
ferent size than the size indi-
cated on the vehicle placard
or tire inflation pressure label,
you should determine the
proper tire inflation pressure
for those tires.) As an added
safety feature, your vehicle
has been equipped with a tire
pressure monitoring system
(TPMS) that illuminates a low
tire pressure telltale when one
or more of your tires is signifi-
cantly under-inflated. Accord-
ingly, when the low tire
pressure telltale illuminates,
you should stop and check
your tires as soon as possi-
ble, and inflate them to the
proper pressure. Driving on a
significantly under-inflated tire
causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces
fuel efficiency and tire tread
life, and may affect the vehi-
cle's handling and stopping
ability. Please note that the
TPMS is not a substitute for
proper tire maintenance, and
it is the driver's responsibility
to maintain correct tire pres-
sure, even if under-inflation
has not reached the level to
trigger illumination of the
TPMS low tire pressure tell-
tale. Your vehicle has also
been equipped with a TPMS
malfunction indicator to indi-
cate when the system is not
operating properly. The TPMS
malfunction indicator is com-
bined with the low tire pres-
sure telltale. When the system
detects a malfunction, the tell-
tale will flash for approxi-
mately one minute and then
remain continuously illumi-
nated. This sequence will
continue upon subsequent
vehicle start-ups as long as
the malfunction exists. When
the malfunction indicator is
illuminated, the system may
not be able to detect or signal
low tire pressure as intended.
TPMS malfunctions may
occur for a variety of reasons,
including the installation of
replacement or alternate tires
or wheels on the vehicle that
prevent the TPMS from func-

This chapter describes all stan-
dard, country-specific and
optional features offered with
the series. It also describes fea-
tures that are not necessarily
available in your vehicle, for
instance, 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.
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 consumption,
the gasoline should be sul-
fur-free or very low in sulfur con-
tent.
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.
To achieve nominal values for
mileage and consumption, fol-
low the specified fuel quality in
the sales literature.
Ethanol should meet the follow-
ing quality standards:
US: ASTM 4806–xx
CAN: CGSB-3.511–xx
xx: comply with the current valid
standard in each case.
The use of fuels of minimum
quality has no influence on the
service life of the engine.

recommendation using sensors
and special algorithms that take
into account the driving condi-

nance corresponding to your
user profile.
Information on service notifica-
tions, refer to page 147, can be

Storage periods during which
the vehicle battery was discon-
nected are not taken into
account.
If this occurs, have a Toyota
dealer update the time-depen-
dent maintenance procedures,
such as checking brake fluid
and, if necessary, changing the
engine oil and the microfil-
ter/activated-charcoal filter.Please consult “Owner's War-

vice and maintenance work.
The manufacturer of your vehi-
cle recommends that mainte-
nance and repair be performed
by a Toyota dealer. Records of
regular maintenance and repair
work should be retained.
Scheduled maintenance should
be performed at specified inter-

Lights and bulbs make an
essential contribution to vehicle
safety.
All headlights and lights are
made using LED technology.
Some items of equipment use
light-emitting diodes installed behind a cover as a light source.
These light-emitting diodes are
related to conventional lasers
and are officially designated as
Class 1 light-emitting diodes.
The manufacturer of the vehicle
recommends that you let your
Toyota dealer perform the work
in case of a malfunction.
Follow the safety information,
refer to page 312.
Condensation can form on the
inside of the headlight glass in
cool or humid weather. When
driving with the lights switched
on, the condensation evapo-
rates after a short time. The
headlight glass does not need to
be changed.
If despite driving with the head-
lights switched on, increasing
humidity forms, for instance
water droplets in the light, have
the headlights checked.

cle from the hazardous area,
push it for a short distance at a
speed of no more than 6 mph/10
km/h.
For rolling or pushing the vehi-
cle, refer to page 133.
The vehicle should only be

When cleaning the vehicle, use
only neutral wheel cleaners hav-
ing a pH value from 5 to 9. Do
not use abrasive cleaning
agents or steam jets above 140
°F/60 °C. Follow the manufac-
turer's instructions.
Aggressive, acidic or alkaline
cleaning agents can destroy the
protective layer of adjacent
components, such as the brake
disc.
After cleaning, apply the brakes
briefly to dry them. The heat
generated during braking dries
brake discs and brake pads and
protects them against corrosion.
Carefully clean components
such as the radiator grille or
door handles with plenty of
water, possibly with shampoo
added, particularly when they have been exposed to road salt.
Environmental influences can
cause surface soiling of rubber
parts and a loss of gloss. Use
only water and suitable cleaning
agents for cleaning.
Treat especially worn rubber
parts with rubber care agents at
regular intervals. When cleaning
rubber seals, do not use any sili-
con-containing vehicle care
products in order to avoid dam-
age or noises.
The wiper blades are cleaned by
using the washer system.
Avoid cleaning the wiper blades
manually, as this may reduce
wiper performance.
Clean with a microfiber cloth.
Dampen cloth lightly with water.
Do not soak the roofliner.
