Driving tips
General driving tips
Rolling with the engine switched off
G
Risk of accident
Never switch the engine off while the vehicle
is in motion.
There is no power assistance for the steering
and the service brake when the engine is not
running.
You will require considerably more effort to
steer and brake and you could therefore lose
control of the vehicle and cause an accident.
Engine oil
!
Vehicles with a diesel particle filter:
If the vehicle is mostly driven for short dis-
tances, it is possible that malfunctions may
occur during the automatic cleaning of the
diesel particle filter. This can lead to engine
damage. Therefore, if you frequently drive
short distances, make sure to drive on
motorways or country roads for 20 minutes
at least every 500 km.
Possible causes/consequences and M Solutions

Applying the brakes
Important safety notes
G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
G
Risk of accident
Make sure that other road users are not
endangered by your braking.
Downhill gradients
On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing a trailer,
you must shift to a lower gear in good time or,
on vehicles with automatic transmission,
select shift range 1, 2 or 3.
i
This also applies if you have activated
cruise control, SPEEDTRONIC or DIS-
TRONIC PLUS.
This will use the braking effect of the engine,
so less braking will be required to maintain
the speed. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. If you need
additional braking, depress the brake pedal
repeatedly rather than continuously.
