DRIVING HINTS
▷ There may be a small amount of smoke
from the exhaust system, even after stop-
ping the engine.
▷ Noise, for example from radiator fan oper-
ation, may be heard, even some minutes
after stopping the engine.
It is normal for the radiator fan to keep running
for several minutes, even after short journeys.
Cleaning the exhaust gas particulate
filter while driving
The diesel particulate filter has a self-clean-
ing feature. No further action is required, such
as adjusting your driving style.
Climate comfort laminated glass
The vehicle glazing offers full protection
against the harmful effects of UV light on the
skin. In addition, the vehicle glazing reduces
heat radiation and ensures less heating of the
interior.
Radio signals
WARNING
Certain vehicle functions may be affected by
interference from high-frequency radio sig-
nals. Such signals are output from a series
of transmission systems, for example from
air traffic beacons or relay stations for mobile
telecommunications.
We recommend you consult your Service
Partner should you experience any difficul-
ties.
Mobile radio in the vehicle
WARNING
There is a possibility of reciprocal interfer-
ence between the vehicle electronics and
mobile radio devices. Radiation is generated
when mobile radio devices are transmitting.

Driving precautions
Online Edition for Part no. 01405A5E758 - VI/22
There is a danger of injury or material dam-
age. If possible, only use mobile radio devi-
ces, for example mobile phones, inside the
vehicle if they are connected directly to an
external aerial or personal eSIM in order to
eliminate reciprocal interference and to divert
the radiation away from the vehicle interior.
Aquaplaning
On wet or slushy roads, a water wedge can
form between the tyres and the road.
This phenomenon is known as aquaplaning
and can cause the tyre to lose contact partially
or fully with the road surface, meaning that the
vehicle can neither be steered, nor the brakes
properly applied.
Driving through water
General
Please comply with the following when driving
through water:
▷ Deactivate the Automatic Start/Stop func-
tion.
▷ Only drive through still water.
▷ Only drive through water up to a max.
depth of 25 cm, 9.8 in.
▷ Drive through water at a walking speed of
no more than 5 km/h, 3 mph.
Safety information
NOTICE
Driving too quickly through excessively deep
water can cause water to enter the engine
compartment, electrical system or transmis-
sion. There is a risk of material damage.
When driving through water, do not exceed
the maximum water depth and maximum
speed specified above.
