Driving instructions
Standing waterPassenger compartment
Driving abroad
Abroad, there is an extensive
Mercedes-Benz service network at your
disposal. If you plan to drive into areas
which are not listed in the index of your
Mercedes-Benz Center directory, you
should request pertinent information from
an authorized Mercedes-Benz Center.Control and operation of radio
transmitters
Radio and telephone
!Do not drive through flooded areas or water
of unknown depth. Before driving through water,
determine its depth. Never accelerate before
driving into water. The bow wave could force
water into the engine and auxiliary equipment,
thus damaging them.
If you must drive through standing water, drive
slowly to prevent water from entering the pas-
senger compartment or the engine compart-
ment. Water in these areas could cause damage
to electrical components or wiring of the engine
or transmission, or could result in water being in-
gested by the engine through the air intake caus-
ing severe internal engine damage. Any such
damage is not covered by the Mercedes-Benz
Limited Warranty.
Warning!G
Always fasten items being carried as
securely as possible.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and cause injury
to vehicle occupants unless the items are
securely fastened in the vehicle.
The trunk is the preferred place to carry
objects.
Warning!G
Please do not forget that your primary
responsibility is to drive the vehicle safely.
Only operate the radio or telephone
1 if road,
weather and traffic conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet
(approximately 14 m) every second.
1Observe all legal requirements.

252 Operation
Engine compartment
Press the front part of the hood.
The hood opens and will automatically
be held in position by gas-filled spring
struts.Closing
Pull the hood upwards in the center,
against the resistance of the gas-filled
spring struts.
Hold the front center part of the hood
with both hands and push it back-
wards. After pushing the hood back-
wards about half-way, you will feel the
hood passing a crest and the resulting
force pulling the hood away from you.
At that point, let go of the hood and let
it fall onto the latches.
The hood should now be locked and
entirely closed.
Check that the hood is properly closed.
If the hood is not properly engaged,
repeat the closing procedure.
!Make sure there is sufficient clearance be-
fore opening the hood. A minimum overhead
clearance of 6.6 ft (2.0 m) is required.
Warning!G
When closing the hood, use extreme caution
not to catch hand or fingers. Be careful that
you do not close the hood on anyone.
Make sure the hood is securely engaged be-
fore driving. Do not continue driving if the
hood can no longer engage after an accident
for example. The hood could otherwise
come loose while the vehicle is in motion
and injure you and/or others.!Make sure the rollers at the rear of the hood
are engaged and the guide pins line up with the
guide holes. Otherwise the hood may be
damaged.

372 Practical hints
Towing the vehicle
Installing/reinstalling towing eye bolt
Take the towing eye bolt1 from its
storage compartment (
page 353).
1Towing eye bolt
Remove cover from the access hole.
Screw towing eye bolt1 clockwise in
to its stop.
Remove the towing eye bolt when you
no longer need it. To do this, carry out
the above steps in reverse order.
Points to bear in mind
The vehicle must not be tow-started.
If the vehicle is to be towed, only tow it
with all wheels on the ground.
If the vehicle has suffered transmission
damage, only tow it with the propeller
shaft disconnected.
Before towing the vehicle, make sure
the battery is connected and charged.
Otherwise you will not be able to switch
on the ignition and move the selector
lever to neutral positionN. There will
then be no power assistance when
steering and braking.
Transporting the vehicle
The towing eye bolt can be used to pull the
vehicle onto a trailer or transporter for
transporting purposes.
Switch on the ignition (page 40).
Move the selector lever to neutral
positionN.
!Only secure the tow bar to the towing eye
bolt. The vehicle could otherwise be damaged.
!Your vehicle is equipped with a front towing
eye bolt only (
page 372).
You cannot tow other vehicles with your vehicle.
!Due to the low clearance height of the SLR,
care must be taken when loading and unloading
from a transporter to avoid damaging the vehicle
body work.
To secure the vehicle, only tie it down by the
wheels or tires. Otherwise it could be damaged.
