About replacing bulbs
Safe vehicle operation depends on proper
exterior lighting and signaling. It is
therefore essential that all bulbs and lamp
assemblies are in good working order at all
times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. Contact an author-
ized electric drive smart center for head-
lamp adjustment. G
WARNING
Bulbs and bulb sockets can be very hot.
Allow the lamp to cool down before changing
a bulb. Otherwise you could be burned if you
touch them.
Keep bulbs out of the reach of children.
Halogen lamps contain pressurized gas. A
bulb can explode if you:
R touch or move it when hot
R drop the bulb
R scratch the bulb
Wear eye and hand protection.
i If the headlamps or front fog lamps* are
fogged up on the inside as a result of
high humidity, driving the vehicle a
distance with the lights on should clear
up the fogging. Notes on bulb replacement:
R
Only use bulbs of the same type and with
the specified watt rating.
R Switch the lights off before replacing a
bulb to prevent short circuits.
R Always use a clean lint-free cloth when
handling bulbs.
R Your hands should be dry and free of oil
and grease.
R Avoid touching the glass of the bulb with
bare fingers.
R If the newly installed bulb does not come
on, contact an authorized electric drive
smart center.
R Have the bulbs for the front fog lamps*
and the LED daytime running lamps*
replaced at an authorized electric drive
smart center. Replacing bulbs

WARNING
For safety reasons, switch off the wipers
and remove the key from the starter switch
before replacing a wiper blade. The wind-
shield wipers could otherwise be set in
motion and cause injury. G
WARNING
Wiper blades are components that are sub-
ject to wear and tear. Replace the wiper
blades at least twice a year, preferably in
the spring and fall. Otherwise the windows
will not be properly wiped. As a result, you
may not be able to observe surrounding
traffic conditions and could cause an acci-
dent.

Preparing the vehicle
Upon experiencing any type of problem
with the vehicle’s tires, switch on the haz-
ard warning flasher, carefully slow down
and exit the roadway in a cautious manner.
X Park the vehicle at a safe distance from
moving traffic on a hard, flat surface
when possible.
X Make sure the tire valve of the damaged
tire is located below the horizontal axle
of the wheel hub.
X Engage the parking brake.
X Turn the steering wheel so that the front
wheels are in a straight ahead position.
X Move the gear selector lever to park
position P.
X Switch off the drive system.
X Remove the key from the starter switch
and take the key with you.
i Open door only when conditions are safe
to do so.
X Have any passenger exit the vehicle at a
safe distance from the roadway. Using the tire repair kit
! Depending on the type of damage on the
tire, the tire sealant could damage the
sensor of the Tire Pressure Monitoring
System (TPMS)*. Such damage is not cov-
ered by the smart Limited Warranty.
When having the damaged tire replaced,
also have the TPMS sensors* checked for
proper function. When the sensor is dam-
aged, the TPMS* will not function prop-
erly. The sensor must then be replaced at
an authorized electric drive smart
center as soon as possible.
i Depending on production date of your
vehicle, it will be equipped with version
1 or version 2 of the tire repair kit.
Please make sure to refer to the descrip- Flat tire

Screw the end of filler hose 0085onto tire
valve 006F.
X Insert electrical plug 0084into 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 006B.
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 0044must 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 006B.
X Unscrew the end of filler hose 0085from
tire valve 006F.
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 0085onto tire
valve 006F.
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
