Winter driving

General information

Have your vehicle winterproofed at a qualified

specialist workshop, e.g. at an authorized

Mercedes-Benz Center, at the onset of

winter.

Observe the notes in the "Winter operation"

section (Y page 323).

Slippery road surfaces

Warning

If the vehicle becomes stuck in snow, make

sure snow is kept clear of the exhaust pipe

and from around the vehicle with the engine

running. Otherwise, deadly carbon monoxide

(CO) gases may enter vehicle interior

resulting in unconsciousness and death.

To assure sufficient fresh air ventilation, open

a window slightly on the side of the vehicle

not facing the wind.

G

Warning!

The outside temperature indicator is not

designed to serve as an ice-warning device

and is therefore unsuitable for that purpose.

Indicated temperatures just above the

freezing point do not guarantee that the road

surface is free of ice. The road may still be icy,

especially in wooded areas or on bridges.

G

Warning

On slippery road surfaces, never downshift in

order to obtain braking action. This could

result in drive wheel slip and reduced vehicle

control. Your vehicle's ABS will not prevent

this type of loss of control.

You should drive particularly carefully on

slippery road surfaces. Avoid sudden

acceleration, steering and braking

maneuvers. Do not use cruise control or

DISTRONIC PLUS.

If the vehicle threatens to skid or cannot be

stopped when moving at low speed:

Shift the transmission to position N.

Warning

Make sure that you do not endanger other

road users when you apply the brakes.

Driving abroad

An extensive Mercedes-Benz Service network

is also available in other countries. The

Service Hotline's current telephone numbers

for use when you are abroad are to be found

in the "Service24h" section of the Service

Booklet.

Cruise control

Important safety notes

Cruise control maintains a constant road

speed for you. It brakes automatically in order

to avoid exceeding the set speed. On long and

steep downhill gradients, especially if the

vehicle is laden, you must select shift range

1, 2 or 3 in good time. By doing so, you will

make use of the braking effect of the engine,

which relieves the load on the brake system

and prevents the brakes from overheating

and wearing too quickly.

Use cruise control only if road and traffic

conditions make it appropriate to maintain a

steady speed for a prolonged period. You can

store any road speed above 20 mph

(30 km/h).

G

Warning

The cruise control is a convenience system

designed to assist the driver during vehicle

operation. The driver is and must always
