Useful features
Roof and trunk lid racks
!To avoid damage to the vehicle and the
dust cover, observe the following:

Once you have secured the dust
cover with the anti-theft device, the
dust cover can be removed only by
using force. This can cause damage
to the dust cover (tearing) or to the
paintwork.


The dust cover anti-theft device will
not prevent burglary or vehicle
theft.
Warning!
G
This vehicle has not been designed to
accommodate any type of roof or trunk lid
rack. Therefore do not fit such accessories.
Otherwise the rack could fall off and cause
serious personal injury.!Do not use any type of roof or trunk lid
rack. Otherwise you will damage the
bodywork or paintwork of your SLR.

228 OperationIn the “Operation” section you will find
detailed information on operating, main-
taining and caring for your vehicle. The first 1000 miles (1500 km)
The more cautiously you treat your vehicle
during the break-in period, the more satis-
fied you will be with its performance later
on. You should therefore observe the fol-
lowing for the first 1000 miles (1500 km):

Drive at varying but moderate road and
engine speeds.


Do not drive faster than 150 mph
(240 km/h).


Break in new tires for the first
100 miles (160 km), therefore avoid
high-speed cornering. Do not exceed a
speed of 125 mph (200 km/h).


Do not drive at engine speeds above
4500 rpm.


Try to avoid heavy load on the engine
(driving at full throttle) and driving at
high engine speeds (maximum of
2/3
of top speed of each gear) during this
break-in period.


Avoid accelerating by kick-down.


Change gears in good time.


Do not attempt to slow the vehicle
down by shifting to a lower gear using
the gear selector lever.


Select positions3,2 or1 only when
driving at moderate speeds (for hill
driving).


Select C as the preferred shift program
(page 173) for the first 1000 miles
1500 km).
After 1000 miles (1500 km), you may grad-
ually bring the vehicle up to full road and
engine speed.
All of the above instructions also apply
when driving the first 1000 miles
(1500 km) after the engine or the rear dif-
ferential has been replaced.
iAlways obey applicable speed limits.

229 Operation
Driving instructions
Driving instructions
Drive sensibly – save fuel
Fuel consumption, to a great extent,
depends on driving habits and operating
conditions.
To save fuel you should:

Keep tires at the recommended tire
inflation pressures.


Remove unnecessary loads.


Allow engine to warm up under low
load use.


Avoid frequent acceleration and decel-
eration.


Have all maintenance work performed
at the intervals specified in the
Maintenance Booklet and as required
by the maintenance service display.
Contact an authorized Mercedes-Benz
Center.
Fuel consumption is also increased by
driving in cold weather, in stop-and-go
traffic, on short trips and in hilly area.
Drinking and driving
Pedals
Warning!
G
Drinking and driving and/or taking drugs
and driving are very dangerous combina-
tions. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgement.
The possibility of a serious or even fatal
accident are greatly increased when you
drink or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Warning!
G
Keep driver’s foot area clear at all times.
Objects stored in this area may impair pedal
movement.

230 OperationDriving instructionsPower assistance
Brakes
Warning!
G
The brake system requires electrical energy
for operation.
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. In such a case, the
red brake warning lamp (
page 298) and
warning messages (
page 304) in the in-
strument cluster come on while driving. To
brake, the driver must then apply signifi-
cantly greater brake pedal pressure and de-
press the pedal much further to obtain the
expected braking effect. If necessary, apply
full pressure to the brake pedal. Brakes are
only applied to the front wheels. Stopping
distance is increased! If there is a malfunc-
tion in the SBC brake system, we recom-
mend that the vehicle be transported with
all wheels off the ground using flatbed or ap-
propriate wheel lift/dolly equipment.
A tow bar must be used if circumstances do
not permit the use of the recommended
towing methods and the vehicle requires
towing with all four wheels on the ground.
Towing the vehicle with all four wheels on
the ground is only permissible for distances
up to 30 miles (50 km) and at a speed not to
exceed 30 mph (50 km/h). For more infor-
mation, see “Towing the vehicle”
(page 357).
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 ve-
hicle.
Warning!
G
After driving in heavy rain for some time
without applying the brakes or through wa-
ter deep enough to wet brake components,
the first braking action may be somewhat
reduced and increased pedal pressure may
be necessary to obtain expected braking ef-
fect. Maintain a safe distance from vehicles
in front.
Resting your foot on the brake pedal will
cause excessive and premature wear of the
brake pads.
It can also result in the brakes overheating
thereby significantly reducing their effec-
tiveness. It may not be possible to stop the
vehicle in sufficient time to avoid an acci-
dent.

231 Operation
Driving instructions
After driving on wet or snow-covered
roads, you should apply your brakes firmly
before parking your vehicle. This produces
heat which serves to dry the brake disks.
If the parking brake is released and the red
brake warning lamp in the instrument clus-
ter stays on, there is a malfunction in the
SBC brake system (
page 298) or the
brake fluid level in the reservoir is too low.
Brake pad wear or a leak in the system may
be the reason for low brake fluid in the res-
ervoir.
Have the brake system inspected immedi-
ately.
All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized
Mercedes-Benz Center.
Only install brake pads and brake fluid rec-
ommended by Mercedes-Benz.
After hard braking, it is advisable to drive
on for some time, rather than immediately
park the vehicle, so the air stream will cool
down the brakes faster.
iThe brake system is designed to decel-
er ate you r S LR f rom hi gh sp ee ds a t the
best possible rate. Depending on the
applied brake force, speed, and ambi-
ent conditions, the brake system may
produce a squeak-type noise when you
apply the brakes at a moderate rate. If
you experience this noise, you should
occasionally test the effectiveness of
the brakes by applying above-normal
braking pressure at high speeds. This
will also enhance the grip of the brake
pads.Warning!
G
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
!Refer to the description of the Brake
Assist System (BAS) (
page 81).
Warning!
G
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that
safe braking is substantially impaired. This
could result in an accident.
Be certain to read and observe the warning
notices on brake pad replacement
(page 85).!When driving down long and steep
grades, relieve the load on the brakes
by shifting into a lower gear to use the
engine’s braking power. This helps pre-
vent overheating of the brakes and re-
duces brake pad wear.
