is a risk of fatal injury. Therefore never leave

the engine running in enclosed spaces

without sufficient ventilation.

Certain engine systems are designed to keep

the level of poisonous components in exhaust

fumes within legal limits.
These systems only work at peak efficiency if

they are serviced exactly in accordance with

the manufacturer's specifications. All work

on the engine must be carried out only by

qualified and authorized Mercedes-Benz

technicians.
The engine settings must not be changed

under any circumstances. Furthermore, all

specific service work must be carried out at

regular intervals and in accordance with the

Mercedes-Benz service requirements. Details

can be found in the Maintenance Booklet.

Braking

Important safety notes

G

WARNING

If you shift down on a slippery road surface in

an attempt to increase the engine's braking

effect, the drive wheels could lose their grip.

There is an increased danger of skidding and

accidents.
Do not shift down for additional engine

braking on a slippery road surface.

Downhill gradients
!

On long, steep gradients, you must

reduce the load on the brakes. In order to

use engine braking effect, restrict the shift

range in good time. This helps you to avoid

overheating the brakes and wearing them

out excessively.
When making use of the engine braking

effect, it is possible that a drive wheel may

not turn for some time, e.g. in the case of

suddenly changing or slippery road surface

conditions. This could cause damage to the

drive train. This type of damage is not

covered by the Mercedes-Benz warranty.

Heavy and light loads

G

WARNING

If you rest your foot on the brake pedal while

driving, the braking system can overheat. This

increases the stopping distance and can even

cause the braking system to fail. There is a

risk of an accident.
Never use the brake pedal as a footrest. Never

depress the brake pedal and the accelerator

pedal at the same time.

!

Depressing the brake pedal constantly

results in excessive and premature wear to

the brake pads.

If the brakes have been subjected to a heavy

load, do not stop the vehicle immediately, but

drive on for a short while. This allows the

airflow to cool the brakes more quickly.

Wet roads

If you have driven for a long time in heavy rain

without braking, there may be a delayed

reaction from the brakes when braking for the

first time.
This may also occur after driving through

water deep enough to wet brake

components.
You have to depress the brake pedal more

firmly. Maintain a greater distance from the

vehicle in front.
After driving on a wet road or having the

vehicle washed, brake firmly while paying

attention to the traffic conditions. This will

warm up the brake discs, thereby drying them

more quickly and protecting them against

corrosion.

Limited braking performance on salt-

treated roads

If you drive on salted roads, a layer of salt

residue may form on the brake discs and
