WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available with limitations, or not at all
.This coul daffect,
for example, the powe rsteering and the brake
boosting effect .You will require considerably
mor eeffort to steer and brake. There is arisk
of an accident.
Do not switch off the ignition while driving.
Drive sensibly –save fuel Observe the fol
lowing tips to save fuel:
X The tyres should always be inflated to the
recomm ended tyr epressure.
X Remove unnecessary lo ads.
X Remov eroof carriers when they are not
needed.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X observe the service intervals in the Service
Booklet or in the service interval display.
Have all the maintenan cework carried in
accordanc ewith Daimler AG regulations.
Fuel consumption also increases when driv-
ing in cold weather, in stop-start traffic and in
hilly terrain. Short journeys
! Vehicles with adiesel particle filter: if
the vehicle is mostly driven for short dis-
tances, it is possible that malfunctions may
occur durin gthe automa ticc leaning of the
diesel particle filter. This may lead to fuel
collectin ginthe engin eoil and cause
engin efailure. Therefore, if you frequently
drive short distances, you should tak ea20
