and security features of your vehicle.
Controls in detail
Here you will find detailed information
about the equipment installed on your ve-

cal innovations. If you are already familiar
with the basic functions of your vehicle,

42 Getting startedAdjustingSeatsWarning!
G
All seat, head restraint, steering wheel, and
rear view mirror adjustments, as well as fas-
tening of seat belts, must be done before
the vehicle is put into motion.Warning!
G
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never ride in a moving vehicle with the seat
back in an excessively reclined position as
this can be dangerous. You could slide un-
der 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
fatal injuries. The seat backrest and seat
belts provide the best restraint when the
wearer is in a nearly upright position and
belts are properly positioned on the body.
Your seat must be adjusted so that you can
correctly fasten your seat belt (
page 50).
Never place hands under the seat or near
any moving parts while a seat is being ad-
justed.
Warning!
G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle.
Even with the SmartKey or the SmartKey
with KEYLESS-GO* removed from the
starter switch or the SmartKey with
KEYLESS-GO* removed from the vehicle,
the power seats can be operated when the
respective door is open.
Therefore, do not leave children unattended
in the vehicle, or with access to an unlocked
vehicle. Unsupervised use of vehicle equip-
ment may cause an accident and / or seri-
ous personal injury.
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
whenever possible. 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 recommended for the size and
weight of the child. For additional informa-
tion, see “Children in the vehicle”
(page 82).
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.

45 Getting started
Adjusting
Raising:
Manually adjust the height of head
restraint 1 by pulling it upward.
If head restraint 1 is fully retracted,
push release button 2 in direction of
arrow and pull head restraint 1 up-
ward.
Lowering:

To lower head restraint 1, push
release button 2 in direction of arrow
and press down on head restraint 1.Head restraint tilt
Manually adjust the angle of the head
restraint.

Push or pull on the lower edge of the
head restraint cushion.
For more information, see “Seats”
(
page 132).
Steering wheel
Steering wheel adjustment, manual
iAdjust the head restraint in such a way
that it is as close to the head as possi-
ble.
Warning!
G
Only adjust the steering wheel with the vehi-
cle at a standstill and make sure the steer-
ing wheel is securely locked in place before
driving off.
Driving without the steering wheel adjust-
ment locked may cause an unexpected
steering wheel movement which could
cause the driver to lose control of the vehi-
cle. Make sure the steering wheel is secure-
ly locked by trying to move it up and down,
and in and out before driving off.

50 Getting startedDrivingFastening the seat beltsWarning!
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 maneu-
vers, 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 airbags can only provide the
protection they were designed to afford if
the occupants are using their seat belts
(page 77).
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. Re-
gardless 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 82).
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.

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
Never let more people ride in the vehicle
than there are seat belts available. Make
sure everyone riding in the vehicle is cor-
rectly restrained with a separate seat belt.
Never use a seat belt for more than one per-
son at a time.Warning!
G
Read and observe the additional warning no-
tices printed in the “Safety and Security”
section (
page 74) and (
page 77).

52 Getting startedDriving
With a smooth motion, pull the belt out
of seat belt outlet1.

Place the shoulder portion of the belt
across the top of your shoulder and the
lap portion across your hips.

Seat belt height adjustment
1Release button

Press release button1 and move the
seat belt height adjuster upward or
downward.
Proper use of seat belts


Do not twist the belt when fastening.


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
the height of the belt outlet
(page 52).


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 per-
son 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 periodically
during travel to make sure that it is
properly positioned.


Make sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.
