To signal minor directional changes, such as
changing lanes, press combination switch to
point of resistance only and release. The corre-
sponding turn signals will flash three times.
!
Do not operate the windshield wipers when
the windshield is dry. Dust that accumulates on
a windshield might scratch the glass and/or
damage the wiper blades when wiping occurs on
a dry windshield. If it is necessary to operate the
wipers in dry weather conditions, always operate
the windshield wipers with windshield washer
fluid (page 53).
!
If anything blocks the windshield wipers
(leaves, snow, etc.), switch them off
immediately.
For safety reasons, stop the vehicle in a safe
location, remove the SmartKey from starter
switch before attempting to remove any
blockage.
The hood must be opened (
page 250) be-
fore folding the wiper arms away from the
windshield. You could otherwise damage the
hood and/or the wiper arm.
Remove the blockage.
Turn the windshield wipers on again.If windshield wipers fail to function at all in
switch positionI,
set the combination switch to the next
highest wiper speed
have the windshield wipers checked at the
nearest authorized Mercedes-Benz Center
57 Getting started
Parking and locking
Locking
Exit the vehicle and close all doors.
Opening a door causes the door win-
dows on that side of the vehicle to
open slightly. They will return to the up
position when the door is closed.
Press the lock button‹ on the
SmartKey (
page 38).
With the hood, trunk and all doors
closed, all turn signal lamps flash three
times. The anti-theft alarm system is
armed.
For more information, see “Locking and
unlocking” (
page 98).
Warning!
G
To prevent possible personal injury, always
keep hands and fingers away from the door
openings when closing the doors. Be espe-
cially careful when small children are
around.
Before closing doors, make sure there is no
possibility of someone getting caught in a
door during closing.Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. A child’s
unsupervised access to a vehicle could
result in an accident and/or serious
personal injury.
Warning!
G
Only Mercedes-Benz SLR McLaren Roadster
722 S:
Because of the carbon fiber the footwell
could be slippery when wet. Be careful when
exiting the vehicle with wet shoe soles, you
could slip on it.!
The door windows will not open or close if
the battery is discharged or the door windows
are impeded by ice. In this case open or close
the door with increased caution. Do not attempt
to force the door opened or closed. Doing so
may damage the door seals or the side window.
i
If you hear a warning signal you have forgot-
ten to switch off the headlamps before opening
the driver’s door.
In addition the message$
Lights Are
Still On
appears in the multifunction display.
Switch off the headlamps.

Anti-theft alarm system
Once the alarm system has been armed, a
visual and audible alarm is triggered when
someone opens
a door
the trunk
the hood
the storage compartment between the
backrests
the storage compartment under the
armrest
The alarm will stay on, even if the activat-
ing element (a door, for example) is imme-
diately closed.The alarm system will also be triggered
when
someone attempts to raise the vehicle
someone opens a door from the inside
if the vehicle was locked with the
SmartKey
someone opens the trunk with the
emergency release button
i
In case the engine cannot be started (yet the
vehicle’s battery is charged), the system is not
operational. Contact an authorized
Mercedes-Benz Center or call
1-800-FOR-MERCedes (in the USA), or
1-800-387-0100 (in Canada).
i
If the alarm stays on for more than
30 seconds, a call to the Response Center is ini-
tiated automatically by the Tele Aid system
(
page 215) provided Tele Aid service was sub-
scribed to and properly activated, and that nec-
essary cellular service and GPS coverage are
available.

Warning!
G
Driving when your engine is overheated
can cause some fluids which may have
leaked into the engine compartment to
catch fire. You could be seriously
burned.
Steam from an overheated engine can
cause serious burns which can occur
just by opening the hood. Stay away
f r o m t h e e n g i n e i f y o u s e e o r h e a r s t e a m
coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of
the vehicle and do not stand near the vehicle
until the engine has cooled down.
!
Excessive coolant temperature triggers the
coolant temperature warning lamp (
page 310)
and a warning in the multifunction display
(
page 340).
The engine should not be operated with the cool-
ant temperature above 248°F (120°C). Doing so
may cause serious engine damage which is not
covered by the Mercedes-Benz Limited
Warranty.
i
During severe operating conditions, e.g.
stop-and-go traffic, the coolant temperature may
rise close to 248°F (120°C).
226 Controls in detailUseful featuresProgramming tips
If you are having difficulty programming
the integrated remote control, here are
some helpful tips:
Check the frequency of the hand-held
remote control5 (typically located on
the reverse side of the remote). The in-
tegrated remote control is compatible
with radio-frequency devices operating
between 280-390 MHz.
Put a new battery in hand-held remote
control5. This will increase the likeli-
hood of the hand-held remote control
sending a faster and more accurate sig-
nal to the integrated remote control.
While performing step 3, hold
hand-held remote control5 at differ-
ent lengths and angles from the signal
transmitter button (2, 3 or4) you
are programming. Attempt varying
angles at the distance of 2 to 5 in
(5 to 12 cm) away or the same angle at
varying distances.
If another hand-held remote control is
available for the same device, try the
programming steps again using that
other hand-held remote control. Make
sure new batteries are in the hand-held
remote control before beginning the
procedure.
Straighten the antenna wire from the
garage door opener assembly. This
may help improve transmitting and/or
receiving signals.
i
Certain types of garage door openers are in-
compatible with the integrated remote control. If
you should experience further difficulties with
programming the integrated remote control,
contact an authorized Mercedes-Benz Center, or
call Mercedes-Benz Customer Assistance
Center (in the USA) at 1-800-FOR-MERCedes, or
Customer Service (in Canada) at
1-800-387-0100.

246 OperationDriving instructions
Coolant temperature
During severe operating conditions and
stop-and-go city traffic, the coolant
temperature may rise close to
approximately 248°F (120°C).
The engine should not be operated with
the coolant temperature over 248°F
(120°C). Doing so may cause serious
engine damage which is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and possible death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one
window fully open at all times.
Warning!
G
Driving when your engine is overheated
can cause some fluids, which may have
leaked into the engine compartment, to
catch fire. You could be seriously
burned.
Steam from an overheated engine can
cause serious burns which can occur
just by opening the hood. Stay away
from the engine if you see or hear steam
coming from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until the
engine has cooled down.
248 OperationAt the gas station
Replace fuel filler cap by turning it
clockwise until it audibly engages.
Close the fuel filler flap until you hear
the latch close shut.
Check regularly and before a long trip

Warning!
G
Overfilling of the fuel tank may create
pressure in the system which could cause a
gas discharge. This could cause the gas to
spray back out when removing the fuel
pump nozzle, which could cause personal
injury. i
Make sure to close the fuel filler flap before
locking your vehicle as the flap locking pin pre-
vents closing after you have locked the vehicle.
