Transporting children safely
The right place for children
Do not leave children unattended in the
vehicle; otherwise, they could endanger
themselves and other persons, e.g. by opening
the doors.<
Children always in the rear
Accident research shows that the safest place
for children is in the back.
Children younger than 13 years of age or
with a height under 5 ft/150 cm may only
be transported in the rear in child restraint sys-
tems which correspond to the age, weight and
height of the child. Otherwise, there is an
increased danger of injury in an accident.<
Children 13 years of age or older must wear a
safety belt as soon as a suitable child restraint
system can no longer be used due to their age,
size and weight.
Exception for front passenger seat
Should it be necessary to use a child
restraint system on the front passenger
seat, the front, knee and side airbags on the
passenger side must be deactivated before
doing so. Otherwise, there is an increased risk
of injury to the child if the airbags are triggered,
even with a child restraint system.<
For more information on automatic deactivation
of the front passenger airbags, refer to page91.
Installing child restraint
systems
Follow child restraint system manufac-
turer's instructions for the selection,
installation and use of child restraint systems.
Otherwise, the degree of protection they offer
may be reduced.<
On front passenger seat
After mounting a child restraint system on
the front passenger seat, make sure that
the front and side airbags on the front passen-
ger side are deactivated, as otherwise there is
an increased risk of injury if the airbags are trig-
gered.<
Backrest width
Before mounting a child restraint system
on the front passenger seat, the backrest
width adjustment must be completely open.<
1.Adjust the backrest width to the fully open
position, refer to page46.
2.Install child's seat.
Child seat security
All rear safety belts and the safety belt for the
front passenger can be locked against pulling
out to secure child restraint systems.
Locking safety belt
1.Secure the child restraint system with the
belt.
2.Pull out the belt webbing completely.
3.Allow the belt webbing to be pulled in and
pull taut against the child restraint system.
The safety belt is locked.

pletely.
LATCH child restraint fixing
system
LATCH: Lower Anchor and Tethers for CHil-
dren.
Follow the system manufacturer's
instructions on installation and use of
LATCH child restraint systems in order not to
impair their protective function.<
Anchor points for LATCH mounts
Before attaching the LATCH child's seat, pull
the belt away from the region of the child
restraint fixing system.
Make sure that both of the lower LATCH
mounts have properly clicked into place
and that the child restraint system is resting
snugly against the backrest. Otherwise, the
protective action may be impeded.<
Rear seats
The mounting points for the LATCH anchors
are located at the positions indicated by arrows
in the gap between the seat and the backrest.
Coupe: child restraint system with
tether strap
Only use the top tether-strap mounting
points to secure child restraint systems,
otherwise the mounting points could be dam-
aged.<
There are two additional mounting points for
child restraint systems with a tether strap, refer
to arrows.
Placement of tether strap
Make sure that the tether strap is not
routed over sharp edges and does not
twist on its way to the upper mounting point;
otherwise, the belt may not properly secure the
child restraint system in the event of an acci-
dent.<

Radio readiness and ignition off
All indicator and warning lamps in the instru-
ment cluster go out.
Starting engine
Do not run the engine in closed rooms,
otherwise the inhalation of toxic exhaust
gases can cause unconsciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless, but highly toxic gas.
Never leave an unattended vehicle with the
engine running, as such a vehicle represents a
potential safety hazard.
Before leaving the vehicle with the engine run-
ning, shift into neutral
* or move the selector
lever into position N and firmly apply the hand-
brake, otherwise the vehicle can begin to roll.<
Avoid frequent starting in quick succes-
sion or repeated starting attempts in
which the engine does not start. Otherwise, the
fuel is not burned at all or is burned inade-
quately and there is a danger of overheating and
damage to the catalytic converter.<
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, drive off at a moderate engine speed.

Handbrake
The handbrake is primarily intended to prevent
the vehicle from rolling while parked; it brakes
the rear wheels.
Indicator lamp
The indicator lamp lights up, and a sig-
nal also sounds when starting off. The
handbrake is applied.
Indicator lamp for Canadian models.
Applying
The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
If exceptional circumstances should
make it necessary to apply the handbrake
while the vehicle is in motion, do not pull it too
firmly. In doing so, continuously press the but-
ton of the handbrake lever. Otherwise, too firm
an application of the handbrake can lock up the
rear wheels and cause the rear of the vehicle to
swerve.<
To prevent corrosion and one-sided brak-
ing action, occasionally engage the hand-
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the hand-
brake is applied.<
Manual transmission*
When shifting into 5th/6th gear, press the
gearshift lever toward the right, otherwise
an inadvertent shift into 3rd or 4th gear could
lead to engine damage.<
When engaging the 1st gear, a slight jolt may
occur. This is operation-related and no reason
for concern.
Reverse gear
Select only when the vehicle is stationary.
Press the gearshift lever to the left, overcoming
a slight resistance.
Shift lights
To achieve the best vehicle acceleration with a
sporty driving style, shift lights in the Head-Up
Display
* indicate the optimum shifting point
briefly before reaching the maximum rpm. Refer
to Shift lights, page64.

Sequential Manual
Transmission with Drivelogic
The concept
The SMG Sequential Manual Transmission
with Drivelogic is an automated manual trans-
mission in which an electrohydraulic system
handles the clutching and gear changes.
The Sequential Manual Transmission is oper-
ated with the selector lever and two shift pad-
dles on the steering wheel.
It offers the following functions:
>Choice of manual or automatic mode:
Sequential mode or Drive mode
>Selection option between different driving
programs, Drivelogic, refer to page63
>Upshift display, shift lights, refer to page64
>Automatic downshifting and prevention of
incorrect shifting even in Sequential opera-
tion
>Automatic double clutching
Selector lever positions
>R: Reverse gear
>N: Neutral, idle
>Β: Drive position:
>+: manual upshifting
>–: manual downshifting
>D/S: switch between Drive mode and
Sequential mode
Shiftlock
Press the brake pedal before shifting out of N;
the shift command will not be executed unless
the brake is applied.
R Reverse
Select only when the vehicle is stationary.
N Idle
Always engage before starting engine.
If the driving situation requires, e.g. when down-
shifting on a slippery road surface, the Sequen-
tial Manual Transmission automatically
clutches and then declutches again, i.e. it is not
necessary to engage idling manually.
The system shifts into N when you open
the driver's door or the hood with the
engine running and do not operate pedals, shift
paddles or the selector lever. To begin driving
after closing the driver's door or the hood, first
shift the selector lever into the N position, and
then shift into drive.<
S Sequential mode
You can shift up and down using the shift pad-
dles or the selector lever. You do not need to
remove your foot from the accelerator to do so.
After every engine start, as soon as the selector
lever is pushed to the right into the drive posi-
tion Β and the brake pedal is pressed, the
Sequential mode is activated.
Starting off is also possible on a level road sur-
face in second gear, e.g. in case of ice.
In the following situations, the Sequential Man-
ual Transmission thinks for you:
>Upshifts and downshifts are executed only
when they will result in a plausible combina-
tion of engine and vehicle speed; thus, for
example, the system will not execute a
downshift that would cause the engine to
overrev.
>When the vehicle is stationary, the trans-
mission automatically downshifts into first
gear.
>Shortly before dropping below a gear-
dependent minimum speed, the transmis-
sion downshifts automatically even without
your intervention.
