gauge.
Insert electrical plug4 into vehicle
cigarette lighter socket.
Turn the SmartKey in the starter switch
to position1 (
page 40).
PressI on electric air pump switch8.
The electric air pump should now
switch on and inflate the tire.After 5 minutes, the pressure gauge must
display at least 26 psi (1.8 bar). The air
hose can become hot during inflation.
Please exercise appropriate caution.
If this tire inflation pressure is not at-
tained, turn off the electric air pump,
detach the filler hose from the tire
valve, and drive vehicle back and forth
very slowly approximately 30 ft (10 m).
This serves to better distribute the
TIREFIT sealant material inside the tire.
Unscrew the air pump’s air hose5
from flange6 of the TIREFIT
container.
Screw air hose5onto tire valve7.
Inflate the tire again.
After attaining a tire inflation pressure
of 26 psi (1.8 bar), press0 on electric
air pump switch8.

than 8 minutes without interruption. Otherwise it
may overheat.
You may operate the air pump again after it has
cooled off.
Warning!G
If a tire inflation pressure of 26 psi (1.8 bar)
is not attained, the tire is too severely
damaged for TIREFIT to provide a reliable
tire repair.
In this case, TIREFIT cannot properly seal
the tire.
Do not drive the vehicle.
Contact the nearest Mercedes-Benz Center
or call Roadside Assistance.


365 Practical hints
Flat tire
Store the electrical plug and the air
hose behind the flap and place the
electrical air pump back in the trunk.
Close the trunk lid.
Drive off immediately.
The TIREFIT sealant will distribute itself
evenly inside the tire.
After driving vehicle for an initial
10 minutes, check tire inflation pres-
sure using the pressure gauge on the
air pump.
If tire inflation pressure is at least
20 psi (1.3 bar), inflate tire to correct
pressure (see placard on driver’s door
B-pillar) and contact a nearest qualified
workshop, e.g. an authorized
Mercedes-Benz Center, to have the
damaged tire replaced.
Recommended duration of use:
A maximum of 300 miles (500 km) at
or below 50 mph (80 km/h) with the
recommended tire inflation pressure.
Warning!G
Do not exceed vehicle speed of
50 mph (80 km/h). A TIREFIT repair is not
designed to operate at higher speeds.
The sticker must be attached on the instru-
ment cluster where it will be easily seen by
the driver.
Vehicle handling characteristics may
change. Adapt your driving accordingly.
Warning!G
If tire inflation pressure has fallen below
20 psi (1.3 bar), do not continue to drive the
vehicle.
Park your vehicle safely away from the road-
way and contact the nearest authorized
Mercedes-Benz Center or Roadside
Assistance.
Have the damaged tire replaced.
Warning!G

ty of the vehicle will be adversely affected,
especially when driving at high speeds.


366 Practical hints
Flat tire
Contact an authorized Mercedes-Benz
Center as soon as possible to obtain a
new TIREFIT kit.
Bring used TIREFIT materials to an
authorized Mercedes-Benz Center for
proper disposal.
Replace your TIREFIT container every
4 years. Replacement containers are
available at your authorized
Mercedes-Benz Center.
Warning!G
Follow recommend tire inflation pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly,
adversely affect handling and fuel economy,
and are more likely to fail from being
overheated.
Do not overinflate tires. Overinflated tires
can adversely affect handling and ride
comfort, wear unevenly, increase stopping
distance, and result in sudden deflation
(blowout) because they are more likely to
become punctured or damaged by road
debris, potholes etc.
Do not overload the tires by exceeding the
specified load limit or vehicle capacity
weight as indicated on the placard on the
driver’s door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout.
Warning!G
Do not exceed vehicle speed of 50 mph
(80 km/h). A TIREFIT repair is not designed
to operate at higher speeds.
The sticker must be attached on the instru-
ment cluster where it will be easily seen by
the driver.
Vehicle handling characteristics may
change. Adapt your driving accordingly.

Batteries
Batteries
Your vehicle is equipped with two batter-
ies:

The starter battery (located in the
trunk)

The battery for electrical consumers
(located in the trunk)
Warning!G
Failure to follow these instructions can
result in severe injury or death.
Never lean over batteries while connecting,
you might get injured.
Observe all safety instructions and precau-
tions when handling automotive batteries
(
page 256).
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water and seek
medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking, etc.
!You must not jump start the vehicle, other-
wise the vehicle electrical systems could be
damaged.
Only use the battery charge unit tested and ap-
proved by Mercedes-Benz for use on the SLR to
charge the battery or maintain the battery
charge. Using other battery chargers may cause
damage to the vehicle and/or personal injury.
Information on charging the batteries
(
page 368).
Have the batteries checked regularly by an
authorized Mercedes-Benz Center. Refer to
Maintenance Booklet for maintenance intervals
or contact an authorized Mercedes-Benz Center
for further information.
If it is necessary to replace the batteries, contact
an authorized Mercedes-Benz Center.
Warning!G
Do not place metal objects on the battery as
this could result in a short circuit.

Batteries
Charging the batteries
You can obtain detailed information on
charging the battery from your authorized
Mercedes-Benz Center.
Warning!G
The brake system requires electrical power
to operate.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. The same applies if
battery is disconnected. To brake, the driver
must then apply significantly greater brake
pedal pressure and depress the pedal much
further to obtain the expected braking ef-
fect. If necessary, apply full pressure to the
brake pedal. Brakes are only applied to the
front wheels. Stopping distance is
increased! Adjust your driving style
accordingly. For more information, see
“Electro-hydraulic brake system”
(
page 86).
Warning!G
With a disconnected battery

you will no longer be able to turn the
SmartKey in the starter switch

the gear selector lever will remain
locked in park positionP
Warning!G
Never charge a battery while still installed in
the vehicle unless the battery charge unit
approved by Mercedes-Benz (supplied with
your vehicle) is being used. Gases may es-
cape during charging and cause explosions
that may result in paint damage, corrosion
or personal injury.
A battery charge unit specially adapted for
Mercedes-Benz vehicles and tested and
approved by Mercedes-Benz is available,
permitting the charging of the battery in its
installed position. Contact an authorized
Mercedes-Benz Center for information and
availability. Charge battery in accordance
with the separate operating instructions for
the battery charger.

370 Practical hints
Towing the vehicle
Mercedes-Benz recommends that the
vehicle be transported with all wheels off
the ground using flatbed or appropriate
wheel lift/dolly equipment.
When circumstances do not permit the
recommended towing methods, the vehi-
cle may be towed with all wheels on the
ground or front wheels raised only so far as
necessary to have the vehicle moved to a
safe location where the recommended
towing methods can be employed.
!Use flatbed or wheel lift/dolly equipment
with SmartKey in starter switch turned to
position0.
Do not tow with sling-type equipment. Towing
with sling-type equipment over bumpy roads will
damage radiator and supports.
To prevent damage during transport, do not tie
down vehicle by its chassis or suspension parts.
!Do not tow-start the vehicle.
!If the vehicle is towed with the front axle
raised, the gear selector lever must be in neutral
positionN and the engine must be shut off
(SmartKey in starter switch position0 or1).
Active braking action through the ESP
® may oth-
erwise seriously damage the brake system which
is not covered by the Mercedes-Benz Limited
Warranty.
When towing the vehicle with all wheels on the
ground, the gear selector lever must be in neu-
tral positionN and the SmartKey must be in
starter switch position2.
When towing the vehicle with all wheels on the
ground or the front axle raised, the vehicle may
be towed only for distances up to 30 miles
(50 km) and at a speed not to exceed 30 mph
(50 km/h).
!To be certain to avoid a possibility of dam-
age to the transmission, however, we recom-
mend the drive shaft be disconnected at the rear
axle drive flange for any towing beyond a short
tow to a nearby garage.
Warning!G
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:

the engine will not run

there is a malfunction in the electro-hy-
draulic brake system

there is a malfunction in the power
supply or in the vehicle’s electrical
system
as that will be necessary to adequately
control the towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make certain that the SmartKey
is in starter switch position2.

With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle. Adapt your driving accordingly.
!Towing of the vehicle should only be done
using the properly installed towing eye bolt.
Never attach tow cable, tow rope or tow rod to
the vehicle chassis, frame or suspension parts.
iTo signal turns while being towed with the
hazard warning flasher in use, turn SmartKey in
starter switch to position2 and activate the
combination switch for the left or right turn
signal in the usual manner – only the selected
turn signal will operate.
Upon canceling the turn signal, the hazard
warning flasher will operate again.
iWhen towing the vehicle with all wheels on
the ground, please note the following:
With the automatic central locking activated and
the SmartKey in starter switch position2 the
vehicle doors lock if the left front wheel as well
as the right rear wheel are turning at vehicle
speeds of approximately 9 mph (15 km/h) or
more.
To prevent the vehicle door locks from locking,
deactivate the automatic central locking
(
page 139) and switch off the tow-away alarm
(
page 94).
iThe gear selector lever will remain locked in
park positionP and the SmartKey will not turn in
the starter switch if the battery is disconnected
or discharged. See notes on the battery
