Warning!
G
A driver’s attention to the road must always
be his/her primary focus when driving. For
your safety and the safety of others, we rec-
o m m e n d t h a t y o u p u l l o v e r t o a s a f e l o c a t i o n
and stop before placing or taking a tele-
phone call. If you choose to use the tele-
phone while driving, please use the
hands-free device and only use the tele-
phone when weather, road and traffic condi-
tions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a ve-
hicle.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of approximately
44 feet (approximately 13.5 m) every sec-
ond.

Operation
Driving instructions
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


Remove roof rack when not in use


Allow engine to warm up under low
load use


Avoid frequent acceleration and decel-
eration


Have all maintenance work performed
at regular intervals by an 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
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 ac-
cident is sharply increased when you drink
or take drugs and drive.
Please don’t drink or take drugs and drive or
allow anyone to drive after 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.

Technical data
Rims and Tires
Rims and Tires
Use only 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
Same size tires
!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 can 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 filler cap of
the vehicle. The tire pressure should be
checked regularly and should only be
adjusted on cold tires. Follow tire man-
ufacturer’s maintenance recommenda-
tion included with vehicle.
