Warning!
Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may
lose control of the vehicle. Continued driving with a flat tire will cause excessive heat build-up
and possibly a fire. G
Warning!
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect
handling and fuel economy, and are more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear
unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are
more likely to become punctured or damaged by road debris, potholes etc. What to do if …

Safety notes
Safe vehicle operation depends on proper
exterior lighting and signaling to a large
degree.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. Contact an
authorized Mercedes-Benz Center for
headlamp adjustment. G
Warning!
Bulbs and bulb sockets can be very hot. Allow
the lamp to cool down before changing a bulb.
Keep bulbs out of reach of children.
Halogen lamps contain pressurized gas. A
bulb can explode if you
R touch or move it when hot
R drop the bulb
R scratch the bulb
Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the
lamp and its components. We recommend
that you have such work done by a qualified
technician.
i Since replacing bulbs is a technically
highly demanding process, we recommend
to have them replaced at an authorized
Mercedes-Benz Center.
i If the headlamps or front fog lamps are
fogged up on the inside as a result of high
humidity, driving the vehicle a distance with
the lights on should clear up the fogging. 312
