ments the existing speakers with more

footwell and a passive subwoofer). Driving systems
Cruise control*
The cruise control maintains the speed you set for your vehicle automatically. On
downhill grades, the cruise control does
not brake the vehicle via the brake system.
The cruise control can only use the braking power of the engine. You must apply the
brakes yourself in order to reduce the
vehicle speed. The cruise control will then
be canceled. G
WARNING
The cruise control is a convenience system designed to assist the driver during vehi-
cle operation. The cruise control cannot
take road, traffic, and weather conditions
into account. The driver is and must always
remain responsible for the vehicle’s speed and for safe brake operation. Do not use the cruise control
R if the road, traffic, and weather condi-
tions do not make it advisable to travel at
a constant speed
R on slippery roads
Rapid changes in tire traction can result
in wheel spin and loss of control.
R when driving in fog
The use of the cruise control is recommen-
ded for driving at a constant speed for
extended periods of time.
With the cruise control is activated and a
speed set, the following message appears
in the multifunction display: U.S. vehicles
:
Cruise control activated
; Set speed Canada vehicles

The cruise control is operated via buttons

Auxiliary power outlet
The auxiliary power outlet supplies power
to the following electrical accessories
when the key is turned to starter switch
position 1:
R the electric air pump, available in con-
junction with the tire repair kit*
R other consumers which operate up to a
maximum of 60 W
! The auxiliary power outlet can accom-
modate 12V DC electrical accessories
designed for use with the standard “cig-
arette lighter” plug type.
Keep in mind, however, that connecting
accessories to the auxiliary power outlet (for example extensive connecting and
disconnecting, or using plugs that do not
fit properly) can damage the auxiliary
power outlet.
The auxiliary power outlet is located in the
lower center console. Auxiliary power outlet
X Turn the key to starter switch position 1.
! Please observe the safety instructions
given in the respective operating
instructions.
Please note that
R if using the auxiliary power outlet the
maximum current drawn may not exceed
5 A or 60 W
R the electric air pump* can be connected
to the auxiliary power outlet for the time it takes to inflate the tire without any
problem
R the vehicle battery will discharge when
current is drawn. 110

X
Screw the end of filler hose ?onto tire
valve G.
X Insert electrical plug Binto the aux-
iliary power outlet (Y page 110).
X Insert the key in the starter switch and
turn it to position 1.
i The vehicle’s 12‑volt battery is drained
by use of the electric air pump. You
should therefore keep the drive system
running while inflating the tire. X
Press Ion electric air pump switch C.
The electric air pump is switched on and inflates the tire.
i First, the sealant is pumped into the
tire. The pressure may briefly increase
to a high value. This is normal and not an
indication of a malfunction. Do not
switch off the electric air pump.
X Let the electric air pump inflate the tire
for a maximum of ten minutes.
Pressure gauge ;must display at least
180 kPa (1.8 bar, 26 psi). !
Do not operate the electric air pump
longer than ten minutes without inter-
ruption. Otherwise it may overheat.
You may operate the electrical air pump
again after it has cooled off.
X If a tire inflation pressure of at least
180 kPa (1.8 bar, 26 psi) is not attained,
turn off the electric air pump by press-
ing 0on electric air pump switch C.
X Unscrew the end of filler hose ?from
tire valve G.
X After clearing the area around the vehi-
cle of people and obstacles, drive vehi-
cle back or forth very slowly approx-
imately 30 ft (10 m).
This serves to better distribute the tire sealant material inside the tire.
X Screw the end of filler hose ?onto tire
valve G.
X Inflate the tire again. G
WARNING
If a tire inflation pressure of
180 kPa (1.8 bar, 26 psi) is not attained, the tire is too severely damaged for the tire
sealant to provide a reliable tire repair.
In this case, the tire sealant cannot prop-
erly seal the tire.
Do not drive the vehicle.
Contact the nearest authorized electric
drive smart center for assistance or call
Roadside Assistance.
X After attaining a tire inflation pressure
of at least 180 kPa (1.8 bar, 26 psi), press 0
on electric air pump switch C.
The electric air pump is switched off.
X Turn the key in the starter switch to
position 0.
X Unscrew the end of filler hose ?from
tire valve G.
X Plug filler hose with the stopper.
X Tire sealant container Eremains

X
Drive to the nearest authorized electric
drive smart center, to have the damaged
tire replaced.
X Contact an authorized electric drive
smart center as soon as possible to
obtain a new filler hose and a new tire
sealant container.
X Bring used tire sealant materials to an
authorized electric drive smart center
for proper disposal.
X Replace your tire sealant container
every 4 years. Replacement containers
are available at any authorized electric
drive smart center. G
WARNING
After changing a tire, contact an author-
ized electric drive smart center to make
sure the bolts holding the wheel to the car
are tight enough. Otherwise, the wheels
could come off. Each bolt should be tight-
ened to a torque of 81 lb‑ft (110 Nm). Sealing a tire (Version 2)
