Important safety notes G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could
affect, for example, the power steering and
the brake boosting effect. You will require
considerably more effort to steer and brake.
There is a risk of an accident.
Do not switch off the ignition while driving. G
WARNING
Mobile communications equipment distracts
the driver from traffic conditions. In addi-
tion, the driver could lose control of the
vehicle. There is a risk of an accident.
As a driver, use mobile communications
equipment only when the vehicle is at a
standstill.
As a vehicle occupant, use mobile communi-
cations equipment only in the designated
area, e.g. the rear passenger compartment. Observe the legal requirements of the country
in which you are driving. Some jurisdictions
prohibit the driver from using a mobile phone
while driving a vehicle.
Always use the hands-free system for tele-
phoning while driving. Only use the telephone
if road traffic conditions permit. If this is not
the case, pull over to a safe location before
using the telephone.
Bear in mind that at a speed of just 30 mph
(approximately
50 km/h), your vehicle is cov-
ering a distance of 44 feet (approximately
14 m) every second.
Drive sensibly – save fuel In order to save fuel, observe the following
tips:
X The tires should always be inflated to the
recommended tire pressure.
X Remove unnecessary loads.
X Remove roof carriers when they are not nee-
ded.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all maintenance work carried out as
indicated by the service intervals in the
Maintenance Booklet or by the service inter-
val display.
Fuel consumption also increases when driving
in cold weather, in stop-start traffic and in
mountainous terrain.
