39 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 re-
movable 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 40)


with the brake pedal firmly depressed
will start the engine (
page 54)
If you wish or should there be a need to in-
sert 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.
!If the SmartKey cannot be turned in the
starter switch, the battery may not be
sufficiently charged.

Check the battery and charge it if
necessary (
page 487).


Get a jump start (
page 496).
To prevent accelerated battery dis-
charge or a completely discharged bat-
tery, always remove the SmartKey from
the starter switch when the engine is
not in operation.
iThe KEYLESS-GO start/stop button
does not need to be removed from the
starter switch when you leave the vehi-
cle. 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 sys-
tems can be switched on or the engine
can be started using the KEYLESS-GO
start/stop button.

consumers.
All lamps (except high beam headlamp
indicator lamp and turn signal indicator
lamps unless activated) in the instru-
ment cluster come on. If a lamp in the
instrument cluster fails to come on
when the ignition is switched on, have
it checked and replaced if necessary. If
a lamp in the instrument cluster re-
mains on after starting the engine or
comes on while driving, refer to “Lamps
in instrument cluster” (
page 404).

43 Getting started
Adjusting
Seat adjustment
The seat adjustment switch is located on
the entry side of each front seat base.
1 Head restraint height*
2Seat cushion tilt
3Seat height
4Backrest tilt
5 Seat fore and aft adjustment

Switch on the ignition (
page 38).
or

Open the respective door (vehicles
with memory function*).
The seat can be adjusted with the re-
spective door opened.
or

Open a front door (vehicles without
memory function*).
The seat can be adjusted within
3 minutes after either front door has
been opened.Seat fore and aft adjustment

Press the switch forward or backward
in direction of arrow5.
Adjust the seat to a comfortable seat-
ing position that still allows you to
reach the accelerator/brake pedal
safely. The position should be as far to
the rear as possible, consistent with
ability to properly operate controls.
!When adjusting the seat backrest tilt
and head restraint height, make sure
the sun visor is folded up (
page 212).
If the head restraint is in the uppermost
position, it could hit and damage the
sun visor.
iThe memory function* (
page 144)
lets you store the settings for the seat
position together with the settings for
the steering wheel column and the ex-
terior rear view mirrors.
!When moving the seat, make sure
there are no items in the footwell or be-
hind the seat. Otherwise you could
damage the seat.

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.

You can start your vehicle without the
SmartKey in the starter switch using the
KEYLESS-GO start / stop button in the

Therefore, never leave children unattended
in the vehicle, as they could otherwise acci-
dentally start the engine.
When leaving the vehicle, always take the
SmartKey with KEYLESS-GO with you and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle.
