The first 1 000 miles (1 500 km)
The more cautiously you treat your vehicle during the
break-in period, the more satisfied you will be with its
performance later on. Therefore, drive your vehicle
during the first 1 000 miles (1 500 km) at moderate
vehicle and engine speeds.
During this period, avoid heavy loads (full throttle
driving) and excessive engine speeds.
Avoid accelerating by kickdown. It is not recommended
to brake the vehicle by manually shifting to a lower gear.
We recommend that you select positions “3”, “2” or “1”
only at moderate speeds (for hill driving).
After 1 000 miles (1 500 km) speeds may be gradually
increased to the permissible maximum.
Maintenance
We strongly recommend that you have your vehicle
serviced by your authorized Mercedes-Benz Center, in
accordance with the Service Booklet at the times called
for by the FSS.
Failure to have the vehicle maintained in accordance
with the Service Booklet at the designated times /
mileage may result in vehicle damage not covered by
the Mercedes-Benz Limited Warranty.
For information on the Flex
ible service system (FSS),
see page 138.

Catalytic converter

Catalytic converter
Your Mercedes-Benz is equipped with monolithic type
catalytic converters, an important element in
conjunction with the oxygen sensors to achieve
substantial control of the pollutants in the exhaust
emissions. Keep your vehicle in proper operating
condition by following our recommended maintenance
instructions as outlined in your Service Booklet.
Caution!
To prevent damage to the catalytic converters, use only
premium unleaded gasoline in this vehicle.
Any noticeable irregularities in engine operation should
be repaired promptly. Otherwise, excessive unburned
fuel may reach the catalytic converter causing it to
overheat, which could start a fire.
Wa r n i n g !
As with any vehicle, do not idle, park or operate
this vehicle in areas where combustible materials
such as grass, hay or leaves can come into contact
with the hot exhaust system, as these materials
could be ignited and cause a vehicle fire.

Driving instructions
Drive sensibly – Save Fuel
Fuel consumption, to a great extent, depends on driving
habits and operating conditions.
To save fuel you should:
• keep tires at the recommended inflation pressures,
• remove unnecessary loads,
• remove roof rack when not in use,
• allow engine to warm up under low load use,
• avoid frequent acceleration and deceleration,
• have all maintenance work performed at regular
intervals by an authorized Mercedes-Benz Center.
Fuel consumption is also increased by driving in cold
weather, in stop-and-go traffic, on short trips and in hilly
country. Drinking and driving
Ped al s
Wa r n i n g !
Drinking or taking drugs and driving can be a very
dangerous combination. Even a small amount of
alcohol or drugs can affect your reflexes,
perceptions and judgement.The possibility of a serious or even fatal accident is
sharply increased when you drink or take drugs
and drive.Please don’t drink or take drugs and drive or allow
anyone to drive after drinking or taking drugs.Wa r n i n g !
Keep driver’s foot area clear at all times. Objects
stored in this area may impair pedal movement.

Power assistance
Brakes Excessive use of road salt and other snow melting
chemicals spread on roads during the winter months
may cause a build up of moisture or residue to form on
the braking components. This build up or residue could
cause light corrosion of the braking components if the
vehicle is parked with the brakes cold. Apply steady and
even braking pressure when stopping the vehicle to
warm up and dry the brake components.
Important!
Please pay attention to the function of the brake assist
system (BAS), see page 271.
The condition of the parking brake system is checked
each time the vehicle is in the shop for the required
maintenance service.
If the parking brake is released and the brake warning
lamp in the instrument cluster stays on, the brake fluid
level in the reservoir is too low.
Brake pad wear or a leak in the system may be the
reason for low brake fluid in the reservoir.
Have the brake system inspected at an authorized
Mercedes-Benz Center immediately.
Wa r n i n g !
When the engine is not running, the brake and
steering systems are without power assistance.
Under these circumstances, a much greater effort is
necessary to stop or steer the vehicle.Wa r n i n g !
After driving in heavy rain for some time without
applying the brakes or through water deep enough
to wet brake components or salty road conditions,
the first braking action may be somewhat reduced
and increased pedal pressure may be necessary to
obtain expected braking effect. Be sure to maintain
a safe distance from vehicles in front.Resting your foot on the brake pedal will cause
excessive and premature wear of the brake pads.It can also result in the brakes overheating thereby
significantly reducing their effectiveness. It may
not be possible to stop the vehicle in sufficient time
to avoid an accident.

Battery
Important!
Battery replacement information:
The maintenance-free battery is located in the engine
compartment on the right hand side.
The service life of the battery is dependent on its
condition of charge. The battery should always be kept
sufficiently charged, in order to last an optimum length
of time. Therefore, we strongly recommend that you have the
battery charge checked frequently, and corrected if
necessary, especially if you use the vehicle less than
approximately 200 miles (300 km) per month,
mostly for short distance trips, or if it is not used for
long periods of time.
Only charge a battery with a battery charger after the
battery has been disconnected from the vehicle’s
electrical circuit.
Always disconnect the battery negative lead first and
connect last.
When removing and connecting the battery, always
make sure that all electrical consumers are off and the
electronic key is in starter switch position 0. The
battery, its filler caps, the vent tube and the opposite
plug must always be securely installed when the vehicle
is in operation.
While the engine is running the battery terminal clamps
must not be loosened or detached, otherwise the
generator and other electronic components would be
damaged.
Wa r n i n g !
Failure to follow these instructions can result in
severe injury or death.Never lean over batteries while connecting, you
might get injured.Battery fluid contains sulfuric acid. Do not allow
this fluid to come in contact with eyes, skin or
clothing. In case it does, immediately flush affected
area with water and seek medical help if necessary.A battery will also produce hydrogen gas, which is
flammable and explosive. Keep flames or sparks
away from battery, avoid improper connection of
jumper cables, smoking etc.
