Emissions
The warning light
lights up:
Emissions are deterio-
rating. Have the vehi-
cle checked as soon
as possible.
 The warning light
flashes under certain
circumstances:
This indicates that
there is excessive mis-
firing in the engine.
Reduce the vehicle
speed and have the
system checked imme-
diately; otherwise, seri-
ous engine misfiring
within a brief period
can seriously damage
emission control com-
ponents, in particular
the catalytic converter.

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

3065-1. MOBILITY
mercially available additives are
suitable for the vehicle. The
vehicle manufacturer recom-
mends using coolant with the
BMW LC-18 specification. Do
not mix additives of different col-
ors. Observe the water - additive
mixture ratio of 50:50. Informa-
tion about suitable additives is
available from your Toyota
dealer.
Depending on the motorization,
there are up to two coolant res-
ervoirs in the engine compart-
ment. Check and top up the
coolant levels on a regular
basis.The coolant may be overfilled in
the coolant reservoir when the
vehicle is delivered from the fac-
tory. The normal coolant level is
achieved by operating the vehi-
cle for a longer period.
The coolant level is indicated
using the maximum mark in the
filler neck of the coolant reser-
voir.
Additional information:
For an overview, refer to page

1
Let the engine cool.
2 Open the hood, refer to page
299.
3 Turn the lid of the coolant
reservoir slightly counter-
clockwise to allow any
excess pressure to dissi-
pate, then open it.
4 Open the coolant reservoir
lid.
5 The coolant level is correct
when it is just below the max-
imum mark in the filler neck.
Safety information
WARNING
With the engine hot and the cool-
ing system open, coolant can
escape and lead to scalding.
There is a risk of injury. Only open
the cooling system with the
engine cooled down.
WARNING
Additives are harmful and incor-
rect additives can damage the
engine. There is a risk of injury
and risk of damage to property.
Do not allow additives to come
into contact with skin, eyes or arti-
cles of clothing. Use suitable addi-
tives only.

before locking the vehicle.
There is an OBD socket on the
driver's side for checking the pri-
mary components in the vehi-
cle's emissions.Safety information
NOTICE
The socket for Onboard Diagno-
sis is an intricate component
intended to be used in conjunction
with specialized equipment to
check the vehicle’s primary emis-
sions system. Improper use of the
socket for Onboard Diagnosis, or
contact with the socket for
Onboard Diagnosis for other than
its intended purpose, can cause
vehicle malfunctions and creates
risks of personal and property
damage. Given the foregoing, the
manufacture of your vehicle
strongly recommends that access
to the socket for Onboard Diagno-
sis be limited to your Toyota
dealer or other persons that have
the specialized
training and
equipment for purposes of prop-
erly utilizing the socket for
Onboard Diagnosis.
