SmartKey.
All turn signal lamps flash once. The
anti-theft alarm system is disarmed.
5Door handle
Press the front part of the door
handle5.
The door swings outwards and
upwards automatically.
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.
Enter the vehicle and insert the
SmartKey in the starter switch.
For more information, see “Locking and
unlocking” (
page 98).
i
The electro-hydraulic brake system is
activated.Warning!
G
Always stand to the rear of the door before
opening it, otherwise the opening action
may cause injury. Outside temperature may
affect door opening speed.!
Ensure sufficient side- and overhead
clearance prior to opening the doors, see “Main
dimensions” (
page 391).
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
entering 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.
47 Getting started
Driving
Place the seat backrest in a nearly up-
right position.
Never use a seat belt for more than one
person at a time.
Do not fasten a seat belt around a per-
son and another object at the same
time. When using a seat belt to secure
infant or toddler restraints or children
in booster seats, always follow the
child seat manufacturer’s instructions.
Check your seat belt during travel to
make sure that it is properly
positioned.
Make sure that the seat belt is always
fitted snugly. Take special care of this
when wearing loose clothing.
Starting the engine
Warning!
G
Do not pass belts over sharp edges. They
could tear.
Do not allow the seat belt to get caught in
the door or in the seat adjustment mecha-
nism. This could damage the seat belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the seat belts.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash, they may
not be able to provide adequate protection.
Damaged seat belts or seat belts that were
highly stressed in an accident must be
replaced. Contact an authorized
Mercedes-Benz Center.
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 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.

Intermittent wiping
The intermittent wiping interval is depen-
dent on the wetness of the windshield.
Turn the combination switch in direc-
tion of arrow 2 to positionI.
After the initial wipe, pauses between
wipes are controlled by the rain sensor.Single wipe
Press combination switch briefly in
direction of arrow1 to the resistance
point.
The windshield wipers wipe one time
without washer fluid.
Wiping with windshield washer fluid
Press combination switch in direction
of arrow1 past the resistance point.
The windshield wipers operate with
washer fluid.
For information on filling up the washer
reservoir, see “Windshield washer system
and headlamp cleaning system”
(
page 257).
!
Do not leave windshield wipers on an
intermittent setting when the vehicle is taken to
an automatic car wash or during windshield
cleaning. Wipers will operate in the presence of
water sprayed on the windshield, and wipers
may be damaged as a result.
!
If you have set intermittent wiping, dirt on
the surface of the rain sensor or optical effects
may cause the windshield wipers to wipe in an
undesired fashion. This could then damage the
windshield wiper blades or scratch the windows.
You should therefore switch off the windshield
wipers when weather conditions are dry.
i
Intermittent wiping is interrupted when the
vehicle is at a standstill and a front door is
opened. This protects persons getting into or out
of the vehicle from being sprayed.
Intermittent wiping will be continued when
all doors are closed and the gear selector
lever is in drive positionD or reverse gearR
or
the wiper setting is changed using the com-
bination switch
i
To prevent smears on the windshield or
noisy/chattering wiper blades, wipe with wind-
shield washer fluid every now and then even
when it is raining.
57 Getting started
Parking and locking

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.

62 Safety and SecurityOccupant safetyAir bagsWarning!
G
Air bags are designed to reduce the poten-
tial of injury and fatality in certain frontal
impacts (front air bags, knee air bags) or
side impacts (head-thorax air bags).
However, no system available today can
completely eliminate injuries and fatalities.
The deployment of the air bags temporarily
releases a small amount of dust from the air
bags. This dust, however, is neither injurious
to your health, nor does it indicate a fire in
the vehicle. The dust might cause some tem-
porary breathing difficulty for people with
asthma or other breathing trouble. To avoid
this, you may wish to get out of the vehicle
as soon as it is safe to do so. If you have any
breathing difficulty but cannot get out of the
vehicle after the air bag inflates, then get
fresh air by opening a window or door.
Warning!
G
To reduce the risk of injury when the front
air bags inflate, it is very important for the
driver and passenger to always be in a prop-
erly seated position and to wear their seat
belts.
For maximum protection in the event of a
collision always be in normal seated position
with your back against the backrest. Fasten
your seat belt and make sure that it is prop-
erly positioned on your body (
page 45).
Since the air bag inflates with considerable
speed and force, a proper seating and hands
on steering wheel position will help to keep
you at a safe distance from the air bag.
Occupants who are unbelted, out of position
or too close to the air bag can be seriously
injured or killed by an air bag as it inflates
with great force in the blink of an eye:
Sit properly belted in a nearly upright
position with your back against the seat
backrest.
Adjust the driver’s seat as far as possi-
ble rearward, still permitting proper op-
eration of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the air bag cover
on the steering wheel must be at least
10 inches (25 cm) or more. You should
be able to accomplish this by a combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, please see an authorized
Mercedes-Benz Center.
Do not lean your head or chest close to
the steering wheel or dashboard.
Keep hands on the outside of steering
wheel rim. Placing hands and arms
inside the rim can increase the risk and
potential severity of hand/arm injury
when driver’s front air bag inflates.
