41 Getting started
Unlocking
SmartKey with KEYLESS-GO*
Vehicles equipped with the KEYLESS-GO
feature are supplied with a SmartKey with
integrated KEYLESS-GO function and a
removable KEYLESS-GO start/stop
button.
With the KEYLESS-GO start/stop button
inserted and the SmartKey with
KEYLESS-GO present in the vehicle, press-
ing the KEYLESS-GO start/stop button

without the brake pedal depressed
corresponds to the various starter
switch positions (
page 42)

with the brake pedal firmly depressed
will start the engine (
page 54)
If you wish or should there be a need to
insert the SmartKey with KEYLESS-GO in
the starter switch, the KEYLESS-GO
start/stop button can be easily removed
by pulling it out of the starter switch.1KEYLESS-GO start/stop button

The SmartKey with KEYLESS-GO must be
located in the vehicle.
Insert KEYLESS-GO start/stop
button1 into starter switch2 (if not
inserted already).
Make sure the automatic transmission
is set toP (
page 185).
Do not depress the brake pedal.
iThe KEYLESS-GO start/stop button does
not need to be removed from the starter switch
when you leave the vehicle. However, always
take the SmartKey with KEYLESS-GO with you
when you leave the vehicle. As long as the
SmartKey with KEYLESS-GO is in the vehicle, the
vehicle’s electrical systems can be switched on
or the engine can be started using the
KEYLESS-GO start/stop button.

43 Getting started
Adjusting
Adjusting
Seats
Warning!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
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
fatal injuries. The seat backrest and seat
belts provide the best restraint when the
wearer is in a position that is as upright as
possible and belts are properly positioned
on the body.
Warning!G
Your seat must be adjusted so that you can
correctly fasten your seat belt (
page 51).
Observe the following points:

Adjust the backrest until your arms are
slightly angled when holding the steer-
ing wheel

Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The po-
sition should be as far back as possible
with the driver still able to operate the
controls properly.

Adjust the head restraint so that it is as
close to the head as possible and the
center of the head restraint supports the
back of the head at eye level.

Never place hands under the seat or
near any moving parts while a seat is be-
ing adjusted.
Failure to do so could result in an accident
and/or serious personal injury.
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.
Therefore, do not leave children unattended
in the vehicle, or with access to an unlocked
vehicle. A child’s unsupervised access to a
vehicle could result in an accident and/or
serious personal injury.

51 Getting started
Driving
Driving
Fastening the seat belts
Warning!G
Make sure that absolutely no objects are ob-
structing the pedal’s range of movement.
Keep the driver’s footwell clear of all obsta-
cles. If there are any floormats or carpets in
the footwell, make sure that the pedals still
have sufficient clearance.
During sudden driving or braking maneu-
vers, the objects could get caught between
the pedals. You could then no longer brake
or accelerate. This could lead to accidents
and injury.
Warning!G
Always fasten your seat belt before driving
off. Always make sure your passengers are
properly restrained.
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 84).
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 appropriately sized
infant restraint, toddler restraint, or booster
seat recommended for the size and weight
of the child. For additional information, see
“Children in the vehicle” (
page 89).
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.
