Notes:
A warning sounds when the driver’s door is opened
while the key is in steering lock position 1 or 0.
With the engine at idle speed, the charging rate of the
alternator (output) is limited.
It is therefore recommended that you turn off
unnecessary electrical consumers while driving in stop-
and-go traffic. This precaution helps to avoid draining of
the battery.
Unnecessary strain on the battery and charging system
may be minimized by turning off the following power
consumers, for example: Heated seats, rear window
defroster.Caution!
To prevent accelerated battery discharge and a possible
dead battery, always remove the key from the steering
lock. Do not leave the key in steering lock position 0.

Before starting
Ensure that parking brake is engaged and that selector
lever is in position “P” or “N”. Turn key in steering lock
to position 2.
Starting
Do not depress accelerator. Briefly turn key in steering
lock clockwise to the stop and release. The starter will
engage until the engine is running.
If engine will not run, and the starting procedure stops,
turn key completely to the left and repeat starting the
engine.
After several unsuccessful attempts, have the system
checked at the nearest authorized Mercedes-Benz
Center.Important!
Due to the installed starter nonrepeat feature, the key
must be turned completely to the left before attempting
to start the engine again.
In areas where temperatures frequently drop below
-4°F (-20°C) we recommend that an engine block heater
be insta lled . You r a ut horized Mercedes-Benz Center will
advise you on this subject.
Turning off
Turn th e key in th e steering lock to position 0 to stop the
engine.
Vehicles with automatic transmission:
The key can only be removed with your foot off the
brake pedal and the selector lever in position “P”.

Park position
The park position is to be used when parking the
vehicle. Engage only with the vehicle stopped.
The park position is not intended to serve as a
brake when the vehicle is parked. Rather, the
driver should always use the parking brake in
addition to placing the selector lever in park to
secure the vehicle.
Note:
The key can be removed from the steering lock
only with the foot off the brake pedal and the
selector lever in position “P”. With the key
removed, the selector lever is locked in
position “P”.
Reverse gear
Shift to reverse gear only with the vehicle
sto pp ed.
Depending on the program mode selector switch
position “S” or “W” the maximum speed in the
reverse gear is different. However, it is not
possible to change the program mode while in
reverse.Neutral
No power is transmitted from the engine to the
drive axle. When the brakes are released, the
vehicle can be moved freely (pushed or towed). Do
not engage “N” while driving except to coast
when the vehicle is in danger of skidding (e.g. on
icy roads, see page 182).
Important!
Coasting the vehicle, or driving for any other
reason with selector lever in “N” can result in
transmission damage that is not covered by the
Mercedes-Benz Limited Warranty.
The transmission automatically upshifts through
5th gear. Position “D” provides optimum driving
characteristics under all normal operating
conditions.
Upshift through 4th gear only. Suitable for
performance driving. To shift from position “D”
to “4”, push selector lever to the left.
Upshift through 3rd gear only. Suitable for
moderately steep hills. Since the transmission
does not shift higher than 3rd gear, this gear
selection will allow use of the engine’s braking
power downhill.

When leaving the vehicle always remove the
electronic key from the steering lock, and lock the
vehicle. Do not leave children unattended in the

Children could release the parking brake, which
could result in an accident or serious injury.

BrakesThe 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 f luid
level in the reservoir is too low.
Brake pad wear or a leak in the system may be the
reason for low brake f luid in the reservoir.
Have the brake system inspected at an authorized
Mercedes-Benz Center immediately.
Al l checks and service work on the brake system shoul d
be carried out by an authorized Mercedes-Benz Center.
Install only brake pads and brake fluid recommended by
Mercedes-Benz.
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, 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.
Wa r n i n g !
If other than recommended brake pads are
installed, or other than recommended brake fluid
is used, t he braking properties of th e vehic le can be
degraded to an extent that safe braking is
substantially impaired. This could result in an
accident.The trunk is the preferred place to carry objects.

Caution!
When driving down long and steep grades, relieve the
load on the brakes by shifting into a lower gear to use
the engine’s braking power. This helps prevent
overheating of the brakes and reduces brake pad wear.
After hard braking, it is advisable to drive on for some
time, rather than immediately parking, so the air stream
will cool down the brakes faster.
Driving off
Apply the service brakes to test them briefly after
driving off. Perform this procedure only when the road
is clear of other traffic.
Warm up the engine smoothly. Do not place full load on
the engine until the operating temperature has been
reached.
W hen sta rting of f on a sl ippery surfa ce, d o not al low one
drive wheel to spin for an extended period with the ESP
switched off. Doing so may cause serious damage to the
drive train which is not covered by the Mercedes-Benz
Limited Warranty.Parking
Important!
Always engage the parking brake whenever parking or
leaving the vehicle. In addition, move selector lever to
position “P”.
When parking on hills, always set the parking brake.
Wa r n i n g !
To reduce the risk of personal injury as a result of
vehicle movement, before
turning off the engine
and leaving the vehicle always:
1. Keep right foot on the service brake pedal.
2. Firmly engage parking brake.
3. Move the selector lever to position “P”
4. Slowly release the service brake pedal.
5. Turn front wheels towards the road curb.
6. Turn the key to steering lock position 0 and
remove.
7. Take the key and lock vehicle when leaving.

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
selector lever to position “N”. Try to keep the vehicle
under control by corrective steering action.
Road salts and chemicals can adversely affect braking
efficiency. Increased pedal force may become necessary
to produce the normal brake effect. We therefore
recommend depressing the brake pedal periodically
when traveling at length on salt-strewn roads. This can
bring road salt impaired braking efficiency back to
normal. A prerequisite is, however, that this be done
without endangering other drivers on the road.
If th e veh ic le is pa rked af ter being d riven on salt treated
roads, th e bra king ef f iciency sh ou ld b e teste d as soon a s
possible after driving is resumed while observing the
safety rules in the previous paragraph.
Wa r n i n g !
If the vehicle becomes stuck in snow, make sure
that snow is kept clear of the exhaust pipe and
from around the vehicle with 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.
