Driving instructions
Drive sensibly – save fuel
Fuel consumption, to a great extent, de-
pends on driving habits and operating con-
ditions.
To save fuel you should:
Keep tires at the recommended infla-
tion 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 Service 
Booklet and as required by the FSS. 
Contact your authorized 
Mercedes-Benz Center.
Fuel consumption is also increased by driv-
ing in cold weather, in stop-and-go traffic, 
on short trips and in hilly country.
Drinking and driving
PedalsPower assistance
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 ac-
cident 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. Ob-
jects stored in this area may impair pedal 
movement.Warning!
G
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.

403 Technical data
Rims and tires
Rims and tires
Only use tires and rims which have been 
specifically developed for your vehicle and 
tested and approved by Mercedes-Benz. 
Other tires and rims 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, ex-
hibit dimensional variations and differ-
ent tire deformation characteristics 
that could cause them to come into 
contact with the vehicle body or axle 
parts. Damage to the tires or the vehi-
cle may be the result.
iFurther information on tires and rims is 
available at any authorized 
Mercedes-Benz Center. A tire inflation 
pressure table is located on the fuel fill-
er flap of the vehicle. The tire pressure 
should be checked regularly and 
should only be adjusted on cold tires. 
Follow tire manufacturer’s mainte-
nance recommendation included with 
vehicle.
