ing MTBE (Methyl Tertiary Butyl Ether) over 15.0% vol. (Oxygen Content 2.7%
weight) in your vehicle.
Fuel containing MTBE over 15.0% vol.
(Oxygen Content 2.7% weight) may re‐ duce vehicle performance and produce
vapor lock or hard starting.
CAUTION
Your New Vehicle Limited Warrantymay not cover damage to the fuelsystem and any performance prob‐lems that are caused by the use offuels containing methanol or fuelscontaining MTBE (Methyl TertiaryButyl Ether) over 15.0% vol. (OxygenContent 2.7% weight.)
Do not use methanol

gasoline which has an octane rating of RON (Research Octane Number) 95 /
AKI (Antiknock Index) 91 or higher (for
Europe) or Octane Rating of RON (Rea‐ search Octane Number) 91 / AKI (Anti‐
knock Index) 87 or higher (except Eu‐
rope).
For customers who do not use good quality gasolines including fuel additives
regularly, and have problems starting
or the engine does not run smoothly, one bottle of additives added to the
fuel tank at every 15,000 km (For Eu‐

priate for your child's height andweight.
NOTICE
Small children are best protected
from injury in an accident when
properly restrained in the rear seat
by a child restraint system that
meets the requirements of the
Safety Standards of your country.
Before buying any child restraint
system, make sure that it has a la‐
bel certifying that it meets Safety
Standards of your country. The re‐
straint must be appropriate for your
child's height and weight. Check the
label on the child restraint for this
information. Refer to L

CHILD RESTRAINT SYSTEM (CRS)
Our recommendation: Children
always in the rear
WARNING
Always properly restrain children inthe vehicle. Children of all ages aresafer when riding in the rear seats.Never place a rearward-facing ChildRestraint System on the front pas‐senger seat, unless the air bag is de‐activated.
Children under age 13 should always
ride in the rear seats and must always
be properly restrained to minimize the
risk of injury in an accident, sudden
stop or sudden maneuver.
According to accident statistics, chil‐ dren are safer when properly restrain‐
ed in the rear seats than in the front
seat. Children too large for a Child Re‐ straint System must use the seat belts
provided.
Most countries have regulations which
require children to travel in approved Child Restraint Systems. The laws governing the age or height/
weight restrictions at which seat belts
can be used instead of Child Restraint System differ among countries, so you
should be aware of the specific require‐
ments in your country, and where you are travelling.
Child Restraint Systems must be prop‐
erly installed in the vehicle seat. Always
use a commercially available Child Re‐ straint System that meets the require‐
ments of your country.
Child Restraint System (CRS)
Infants and younger children must be
restrained in an appropriate rearward
facing or forward-facing CRS that has first been properly secured to the seat
of the vehicle. Read and comply with
the instructions for installation and use provided by the manufacturer of the
Child Restraint System.
WARNING
•Always follow the Child RestraintSystem manufacturer’s instruc‐tions for installation and use.
(Continued)
(Continued)
•Always properly restrain your childin the Child Restraint System.
•Do not use an infant carrier or achild safety seat that L

• Select a Child Restraint System thatfits the vehicle seating position where it will be used.
For the suitability of Child Restraint
Systems on the vehicle's seating po‐ sitions, please refer to the installa‐
tion tables on pages 4-36 and
4-39 to 4-41.
• Read and comply with the warnings and instructions for installation and
use provided with the Child Restraint System.
Child Restraint System types
There are three main types of Child Re‐
straint Systems: rearward-facing, for‐ ward-facing and booster Child Re‐
straint Systems.
They are classified according to the
child’s age, height and weight.
$34#
Rearward-facing Child Restraint Sys‐tem
A rearward-facing Child Restraint Sys‐ tem provides restraint with the seating
surface against the back of the child.
The harness system holds the child in place, and in an accident, acts to keep
the child positioned in the Child Re‐
straint Systems and reduce the stress to the fragile neck and spinal cord. All children under the age of one year
must always ride in a rearward facing
Child Restraint System. There are dif‐ ferent types of rearward-facing Child
Restraint Systems: infant-only Child
Restraint Systems can only be used rearward-facing. Convertible and 3-
in-1 Child Restraint Systems typically
have higher height and weight limits for
the rearward-facing position, allowing you to keep your child rearward-facing
for a longer period of time.
Keep using Child Restraint Systems in
the rearward-facing position as long as children fit within the height and
weight limits allowed by the Child Re‐
straint System's manufacturer.

Forward-facing Child Restraint System
A forward-facing Child Restraint Sys‐
tem provides restraint for the child’s body with a harness. Keep children in a
forward-facing Child Restraint System
with a harness until they reach the top height or weight limit allowed by your
Child Restraint System’s manufacturer.
Once your child outgrows the forward-
facing Child Restraint System, your child is ready for a booster seat.
Booster seats
A booster seat is a Child Restraint Sys‐
tem designed to improve the fit of the
vehicle’s seat belt system. A booster seat positions the seat belt so that it
fits properly over the stronger parts of
your child’s body. Keep your children in booster seats until they are big enough
to fit in a seat belt properly.
For a seat belt to fit properly, the lap
belt must lie comfortable across the upper thighs, not the stomach. The
shoulder belt should lie comfortable
across the shoulder and chest and not across the neck or face. Children under
age 13 must always be properly re‐
strained to minimize the risk of injury in an accident, sudden stop or sudden
maneuver.
Installing a Child Restraint
System (CRS)
WARNING
Before installing your Child RestraintSystem always:Read and follow the instructionsprovided by the manufacturer of theChild Restraint System.Failure to follow all warnings and in‐structions could increase the risk ofthe SERIOUS INJURY or DEATH if anaccident occurs.
WARNING
If the vehicle headrest preventsproper installation of a Child Re‐straint System, the headrest of therespective seating position shall bereadjusted or entirely removed.
After selecting a proper Child Restraint
System for your child and checking that the Child Restraint System fits properly
on the seating position, there are three
general steps for a proper installation: •
Properly secure the Child RestraintSystem to the vehicle.
All Child Re‐
straint Systems must be secured to
the vehicle with the lap belt or lap
part of a lap/shoulder belt or with the
ISOFIX toptether and/or ISOFIX an‐ chorage and/or with the support leg.
•
Make sure the Child Restraint Systemis firmly secured. After installing a
Child Restraint System to the vehicle,
push and pull the seat forward and
from side-to-side to verify that it is securely attached to the seat. A Child
Restraint System secured with a seat
belt should be installed as firmly as
possible. However, some side-to-side
movement can be expected. When in‐ stalling a Child Restraint System, ad‐
just the vehicle seat and seatback (up
and down, forward and rearward) so
that your child fits in the Child Re‐ straint System in a confortable man‐
ner.
•
Secure the child in the Child RestraintSystem. Make sure the child is prop‐
erly strapped in the Child Restraint
System according to the Child Re‐ straint System manufacturer’s in‐
structions.

•Loss of control often occurs if twoor more wheels drop off the road‐way and the driver oversteers toreenter the roadway.
•In the event your vehicle leavesthe roadway, do not steer sharply.Instead, slow down before pullingback into the travel lanes.
•Never exceed posted speed limits.
WARNING
If your vehicle becomes stuck insnow, mud, sand, etc., then you mayattempt to rock the vehicle free bymoving it forward and backward. Donot attempt this procedure if peopleor objects are anywhere near the ve‐hicle. During the rocking operationthe vehicle may suddenly move for‐ward of backward as it becomes un‐stuck, causing injury or damage tonearby people or objects.
Moving up a steep grade from a
standing start
To move up a steep grade from a
standing start, depress the brake pedal,
shift the shift lever to D (Drive). Select
the appropriate gear depending on load weight and steepness of the grade, and
release the parking brake. Depress the
accelerator gradually while releasing the brake pedal.
When accelerating from a stop on asteep hill, the vehicle may have a ten‐dency to roll backwards. Shifting theshift lever into 2 (Second Gear) will helpprevent the vehicle from rolling back‐wards.
