They could accidentally injure
themselves or others through
inadvertent operation of the ve-
hicle. Also, on hot or sunny days,
the temperature in a closed ve-
hicle could quickly become high
enough to cause severe or pos-
sibly fatal injuries.
. Help prevent children, adults or
animals from locking themselves
in the trunk. On hot or sunny
days, the temperature in the
trunk could quickly become high
enough to cause death or serious
heat-related injuries including
brain damage to anyone locked
inside, particularly for small chil-
dren.
. When leaving the vehicle, close
all windows and lock all doors.
Also make certain that the trunk
is closed.
For instructions and precautions, carefully
read the following sections.
. For the seatbelt system, refer to “ Seat-
belts ” F 1-11.
. For the child restraint system, refer to
“ Child restraint systems ” F 1-21.
. For the SRS airbag system, refer to
“ *SRS airbag (Supplemental Restraint System airbag) ” F 1-33.
& Engine exhaust gas (carbon
monoxide) WARNING. Never inhale engine exhaust gas.
Engine exhaust gas contains
carbon monoxide, a colorless
and odorless gas which is dan-
gerous, or even lethal, if inhaled.
. Always properly maintain the en-
gine exhaust system to prevent
engine exhaust gas from enter-
ing the vehicle.
. Never run the engine in a closed
space, such as a garage, except
for the brief time needed to drive
the vehicle in or out of it.
. Avoid remaining in a parked
vehicle for a lengthy time while
the engine is running. If that is
unavoidable, then use the venti-
lation fan to force fresh air into
the vehicle.
. Always keep the front ventilator
inlet grille free from snow, leaves
or other obstructions to ensure
that the ventilation system al-
ways works properly. . If at any time you suspect that
exhaust fumes are entering the
vehicle, have the problem
checked and corrected as soon
as possible. If you must drive
under these conditions, drive
only with all windows fully open.
. Keep the trunk lid closed while
driving to prevent exhaust gas
from entering the vehicle.
& Drinking and driving
WARNINGDrinking and then driving is very
dangerous. Alcohol in the blood-
stream delays your reaction time
and impairs your perception, judg-
ment and attentiveness. If you drive
after drinking – even if you drink just
a little – it will increase the risk of
being involved in a serious or fatal
accident, injuring or killing yourself,
your passengers and others. In
addition, if you are injured in the
accident, alcohol may increase the
severity of that injury.
Please don ’ t drink and drive.
Drunken driving is one of the most

General information & California proposition 65
warning WARNINGEngine exhaust, some of its consti-
tuents, and certain vehicle compo-
nents contain or emit chemicals
known to the State of California to
cause cancer and birth defects or
other reproductive harm. In addi-
tion, certain fluids in vehicles and
certain components of product wear
contain or emit chemicals known to
the State of California to cause
cancer and birth defects or other
reproductive harm.
& California Perchlorate Advi-
soryCertain vehicle components such as air-
bag modules, seatbelt pretensioners and
keyless entry transmitter batteries may
contain perchlorate material. Special
handling may apply for service or vehicle
end of life disposal. See www.dtsc.ca.gov/
hazardouswaste/perchlorate. & Noise from under the vehicle
NOTE You may hear a noise from under the
vehicle approximately 5 to 10 hours
after the engine is turned off. However,
this does not indicate a malfunction.
This noise is caused by the operation
of the fuel evaporation leakage check-
ing system and the operation is normal.
The noise will stop after approximately
15 minutes.
& Event data recorder This vehicle is equipped with an event
data recorder (EDR). The main purpose of
an EDR is to record, in certain crash or
near crash-like situations, such as an air
bag deployment or hitting a road obstacle,
data that will assist in understanding how
a vehicle ’ s systems performed. The EDR
is designed to record data related to
vehicle dynamics and safety systems for
a short period of time, typically 30 seconds
or less. The EDR in this vehicle is
designed to record such data as:
. How various systems in your vehicle
were operating;
. Whether or not the driver and passen-
ger safety belts were buckled/fastened;
. How far (if at all) the driver was
depressing the accelerator and/or brake pedal; and,
. How fast the vehicle was traveling.
These data can help provide a better
understanding of the circumstances in
which crashes and injuries occur. NOTE:
EDR data are recorded by your vehicle
only if a non-trivial crash situation occurs;
no data are recorded by the EDR under
normal driving conditions and no personal
data (e.g., name, gender, age, and crash
location) are recorded. However, other
parties, such as law enforcement, could
combine the EDR data with the type of
personally identifying data routinely ac-
quired during a crash investigation.
To read data recorded by an EDR, special
equipment is required, and access to the
vehicle or the EDR is needed. In addition
to the vehicle manufacturer, other parties,
such as law enforcement, that have the
special equipment, can read the informa-
tion if they have access to the vehicle or
the EDR.8

Seat, seatbelt and SRS airbags/Seat heater
are located on the top of the seatback until
the head restraint locks. Press and hold
the release button to lower the head
restraint.
NOTE When the head restraint cannot be
pulled out or installed due to insuffi-
cient clearance between the head re-
straint and the roof, tilt the seat and
then perform the installation and re-
moval tasks.
! Head restraint angle adjustment
The angle of the head restraint can be
adjusted in several steps. While maintain-
ing a suitable driving posture, adjust the
head restraint to a position where the back
of your head is as close to the head
restraint as possible. To tilt:
Tilt the head restraint by hand to the
preferred position. A click will be audible
when the head restraint is locked.
To return:
Tilt the head restraint once as far forward
as it can go. The head restraint will
automatically return to the fully upright
position. Then, adjust the head restraint
again to the preferred angle. Seat heater (if equipped) The front seats are equipped with a seat
heater.
The seat heater operates when the igni-
tion switch is either in the “ ACC ” or “ ON ”
position.
CAUTION. People with delicate skin may
suffer slight burns even at low
temperatures if they use the seat
heater for a long period of time.
When using the heater, always be
sure to warn the persons con-
cerned.
. Do not put anything on the seat
which insulates against heat,
such as a blanket, cushion, or
similar items. This may cause the
seat heater to overheat.
. When the vehicle ’ sinterioris
warmed enough or before you
leave the vehicle, be sure to turn
off the seat heater.
NOTE
Use of the seat heater for a long period
of time while the engine is not running1-6

considerable speed and force
and can injure or even kill chil-
dren, especially if they are not
restrained or improperly re-
strained. Because children are
lighter and weaker than adults,
their risk of being injured from
deployment is greater.
For that reason, we strongly
recommend that ALL children
(including those in child seats
and those that have outgrown
child restraint devices) sit in the
REAR seat properly restrained at
all times in a child restraint
device or in a seatbelt, whichever
is appropriate for the child ’ s age,
height and weight.
Secure ALL types of child re-
straint devices (including for-
ward facing child seats) in the
REAR seats at all times.
According to accident statistics,
children are safer when properly
restrained in the rear seating
positions than in the front seat-
ing positions.
For instructions and precautions
concerning the child restraint
system, refer to “ Child restraint
systems ” F 1-21. . NEVER INSTALL A FORWARD
OR REARWARD FACING CHILD
SEAT IN THE FRONT SEAT.
DOING SO RISKS SERIOUS IN-
JURY OR DEATH TO THE CHILD
BY PLACING THE CHILD ’ S HEAD
TOO CLOSE TO THE SRS AIR-
BAG.
. Never allow a child to stand up,
or to kneel on the front passen-
ger ’ s seat, or never hold a child
on your lap or in your arms. The
SRS airbag deploys with consid-
erable force and can injure or
even kill the child.
CAUTION. When the SRS airbag deploys,
some smoke will be released.
This smoke could cause breath-
ing problems for people with a
history of asthma or other
breathing trouble. If you or your
passengers have breathing pro-
blems after SRS airbag deploys,
get fresh air promptly. . A deploying SRS airbag releases
hot gas. Occupants could get
burned if they come into direct
contact with the hot gas.
NOTE . When you sell your vehicle, we urge
you to explain to the buyer that it is
equipped with SRS airbags by alerting
the buyer to the applicable section in
this Owner ’ s Manual.
. If the SRS airbag deploys, fuel
supply will be cut off to reduce the risk
of fire caused by leaking fuel. For
details about restarting of the engine,
refer to “ If your vehicle is involved in
an accident ” F 9-18.Seat, seatbelt and SRS airbags/*SRS airbag (Supplemental Restraint System airbag)

2) Submaster key
3) Sub key
4) Key number plate
Three types of keys are provided for your
vehicle.
CAUTION
Do not attach a large key holder or
key case to either key. If it bangs against your knees while you are
driving, it could turn the ignition
switch from the “ ON ” position to the
“ ACC ” or “ LOCK ” position, thereby
stopping the engine.
& Key number plate The key number is stamped on the key
number plate attached to the key set.
Write down the key number and keep it in
another safe place, not in the vehicle. This
number is needed to make a replacement
key if you lose your key or lock it inside the
vehicle. Refer to “ Key replacement ” F 2-4.Immobilizer The immobilizer system is designed to
prevent an unauthorized person from
starting the engine. Only keys registered
with your vehicle ’ s immobilizer system can
be used to operate your vehicle. This
system, however, is not a 100% anti-theft
guaranty.
For models with “ keyless access with
push-button start system ” :
If you press the push-button ignition
switch when carrying an unregistered
access key, the switch will not turn to the
“ ON ” position and the engine will not start.
For models without “ keyless access
with push-button start system ” :
Even if an unregistered key fits into the
ignition switch and can be turned to the
“ START ” position, the engine will auto-
matically stop after several seconds.
If the engine does not start, perform either
of the following procedures.
. Perform the procedure described in
“ Starting engine ” F 9-17 (models with
“ keyless access with push-button start
system ” ).
. Pull out the key once before trying
again (models without “ keyless access
with push-button start system ” ). Refer toKeys and doors/Keys
