Winter driving instructions
The most important rule for slippery or icy
roads is to drive sensibly and to avoid
abrupt acceleration, braking and steering
maneuvers. Do not use the cruise control
system under such conditions.
When the vehicle is in danger of skidding,
move gear selector lever to positionN. Try
to keep the vehicle under control by cor-
rective steering action.
iFor information on speed rating for
winter tires, see “Winter driving”
(page 336).
For additional general information on
tire speed markings on tire sidewall,
see “Tire speed rating” (
page 324).
iFor more information on driving with
snow chains, see “Snow chains”
(page 337).

473 Technical terms
Control system
The control system is used to call up
vehicle information and to change
component settings. Information and
messages appear in the multifunction
display. The driver uses the buttons on
the multifunction steering wheel to
navigate through the system and to
adjust settings.
Cruise control
Driving convenience system for auto-
matically maintaining the vehicle speed
set by the driver.
Distronic*
A driving convenience cruise control
system which helps the driver maintain
a pre-selected speed:
If there is no vehicle directly ahead,
the system operates in the same
way as conventional ->cruise con-
trol.
If a slower moving vehicle is ahead,
Distronic will reduce your vehicle
speed to the extent permitted by
reduced throttle and up to 20%
braking power to maintain the pre-
set minimum following distance.
DOT
(Department o
f Transportation)

page 332)
DTR
(->Distronic*)
Engine number
The number set by the manufacturer
and placed on the cylinder block to
uniquely identify each engine pro-
duced.Engine oil viscosity
Measurement for the inner friction
(viscosity) of the oil at different temper-
atures. The higher the temperature an
oil can tolerate without becoming thin,
or the lower the temperature it can tol-
erate without becoming viscous, the
better the viscosity.
ESP
®(Electronic S
tability Pr

Improves vehicle handling and direc-
tional stability.
ETD
(E
mergency T
