Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that the head re-
straint supports the back of the head at eye
level. This will reduce the potential for injury
to the head and neck in the event of an ac-
cident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are
intended to help reduce injuries during an
accident.

Driving
Driving
Fastening the seat beltWarning!
G
Do not lay any objects in the driver’s foot-
well. Be careful that floor mats or carpets in
the driver’s footwell have sufficient clear-
ance for the pedals.
During sudden driving or braking maneuvers
the objects could get caught between the
pedals. You could then no longer brake or
accelerate.Warning!
G
Always fasten your seat belt before driving
off. Always make sure your passengers are
properly restrained, even those sitting in the
rear and pregnant women.
Failure to wear and properly fasten and po-
sition your seat belt greatly increases your
risk of injuries and their likely severity in an
accident. You and your passengers should
always wear seat belts.
If you are ever in an accident, your injuries
can be considerably more severe without
your seat belt properly buckled. Without
your seat belt buckled, you are much more
likely to hit the interior of the vehicle or be
ejected from it. You can be seriously injured
or killed.
In the same crash, the possibility of injury or
death is lessened if you are wearing your
seat belt. The air bags can only provide the
protection they were designed to afford if
the occupants are using their seat belts
(page 69).
Warning!
G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing position. Thus, we strongly recommend
that children be placed in the rear seats.
Regardless of seating position, children
12 years old and under must be seated and
properly secured in an appropriate infant or
toddler restraint, or booster seat recom-
mended for the size and weight of the child.
For additional information, see “Children in
the vehicle” (
page 74).
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle
and/or the child is not properly secured in
the child restraint.

With a smooth motion, pull the belt

Place the shoulder portion of the belt
across the top of your shoulder and the
lap portion across your hips.
Push latch plate1 into buckle3 until
it engages.
If necessary, tighten the lap portion to
a snug fit by pulling shoulder portion
up.
Warning!
G
Never let more people ride in the vehicle
than there are seat belts available. Be sure
everyone riding in the vehicle is correctly
restrained with a separate seat belt. Never
use a seat belt for more than one person at
a time.Warning!
G
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position
as this can be dangerous. You could slide
under the seat belt in a collision. If you slide
under it, the belt would apply force at the ab-
domen or neck. That could cause serious or
even fatal injuries. The seat backrest and
seat belt provide the best restraint when the
wearer is in a nearly upright position and the
belt is properly positioned on the body.
Warning!
G
Read and observe the additional warning
notices printed in the “Safety and Security”
section (
page 66) and (
page 69).

Adjust seat belt so that the shoulder
portion is located as close as possible
to the middle of the shoulder (it should
not touch the neck). Never pass the
shoulder portion of the belt under your
arm. For this purpose, you can adjust

Position the lap belt as low as possible
on your hips (over hip joint) and not
across the abdomen.
Place the seat backrest in a nearly
upright position.
Never use a seat belt for more than one
person at a time.
Do not fasten a seat belt around a
person and another object at the same
time.
When using a seat belt to secure infant
or toddler restraints or children in
booster seats, always follow the child
seat manufacturer’s instructions.
Check your seat belt during travel to
make sure that it is properly posi-
tioned.
Make sure that the seat belt is always
fitted snugly. Take special care of this
when wearing loose clothing.

result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.!If you hear a warning signal and the
message
Release parking brake
ap-
pears in the multifunction display when
driving off, you have forgotten to re-
lease the parking brake.
!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.
iOnce the vehicle is in motion, the auto-
matic central locking system engages
and the locking knobs drop down.
For more information, see “Automatic
central locking” (

!Do not run cold engine at high engine
speeds. Running a cold engine at high
engine speeds may shorten the service
life of the engine.
!Wait for the gear selection process to
complete before setting the vehicle in
motion.!Place the gear selector lever in
positionP orR only when the vehicle is
stopped in order to avoid damaging the
transmission.

Vehicles with rain sensor*:
Intermittent wiping interval is dependent
on wetness of windshield.
Turn the combination switch to

Vehicles with rain sensor*:
After the initial wipe, pauses between
wipes are automatically controlled by
the rain sensor.
!Do not operate the windshield wipers
when the windshield is dry. Dust that
accumulates on a windshield might
scratch the glass and/or damage the
wiper blades when wiping occurs on a
dry windshield. If it is necessary to op-
erate the windshield wipers in dry
weather conditions, always operate the
windshield wipers with windshield
washer fluid (
page 55).
!Vehicles with rain sensor*:
Do not leave windshield wipers in
intermittent setting when the vehicle is
taken to an automatic car wash or
during windshield cleaning. Windshield
wipers will operate in the presence of
water sprayed on the windshield, and
windshield wipers may be damaged as
a result.
iIntermittent wiping is interrupted when
the vehicle is at a standstill and a front
door is opened. This protects persons
getting into or out of the vehicle from
being sprayed.
Intermittent wiping will be continued
when
all doors are closed

cles with manual transmission)
or
