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
deceleration.


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 judgment.
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
Make sure that absolutely no objects are ob-
structing the pedals’ range of movement.
Keep the driver’s footwell clear of all obsta-
cles. If there are any floormats or carpets in
the footwell, make sure that the pedals still
have sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents
and/or injury.

385 Technical data
Rims and tires
Rims and tires
!
For safety reasons, only use tires and rims
which have been tested and approved by
Mercedes-Benz for use on SLR vehicles. Tires
approved by Mercedes-Benz are developed to
provide best possible performance in conjunc-
tion with the driving safety systems on your
vehicle such as ABS or ESP
®.
!
Using tires and rims other than those ap-
proved by Mercedes-Benz can have detrimental
effects, such as


Poor handling characteristics


Increased noise


Increased fuel consumption
Moreover, tires and rims not approved by
Mercedes-Benz may, under load, exhibit dimen-
sional variations and different tire deformation
characteristics that could cause them to come
into contact with the vehicle body or axle parts.
This may result in damage to the tires or the
vehicle.
i
Further information on tires and rims is
available at any authorized Mercedes-Benz Cen-
ter. A placard with the recommended tire infla-
tion pressures is located on the driver’s door
B-pillar. Some vehicles may have supplemental
tire pressure information for driving at high
speeds (
page 269) or for vehicle loads less
than the maximum loaded vehicle condition. If
such information is provided, it can be found on
the placard located on the inside of the fuel filler
flap. The tire pressure should be checked regu-
larly and should only be adjusted on cold tires.
Follow tire manufacturer’s maintenance
recommendation included with vehicle.
