Warning!
G
A driver’s attention to the road must always
be his/her primary focus when driving.
For your safety and the safety of others, we
recommend that you pull over to a safe loca-
tion and stop the vehicle before requesting
or receiving any info services.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of approximately
44 feet (approximately 13.5 m) every sec-
ond.
!The Tele Aid system utilizes the cellular
network for communication and the
GPS (Global Positioning System) satel-
lites for vehicle location. If either of
these signals are unavailable, the
Tele Aid system may not function and if
this occurs, assistance must be sum-
moned by other means.Warning!

248 OperationThe first 1000 miles (1500 km)In the "Operation" section you will find de-
tailed information on operating, maintain-
ing and caring for your vehicle.
The first 1000 miles (1500 km)The more cautiously you treat your vehicle
during the break-in period, the more satis-
fied you will be with its performance later
on.

Drive your vehicle during the first
1000 miles (1500 km) at varying but
moderate vehicle and engine speeds.


During this period, avoid heavy loads
(full throttle driving) and excessive en-
gine speeds (no more than
2⁄3 of maxi-
mum rpm in each gear).


Avoid accelerating by kick-down.


Do not brake the vehicle by shifting to
a lower gear using the selector lever.


Select positions3, 2 or1 only when
driving at moderate speeds (for hill
driving).
After 1000 miles (1500 km) you may grad-
ually increase vehicle and engine speeds
to the permissible maximum.

Drive sensibly – save fuel
Fuel consumption, to a great extent, de-
pends on driving habits and operating con-
ditions.
To save fuel you should:

Keep tires at the recommended infla-
tion pressures.


Remove unnecessary loads.


Remove roof rack when not in use.


Allow engine to warm up under low
load use.


Avoid frequent acceleration and decel-
eration.


Have all maintenance work performed
at regular intervals by an authorized
Mercedes-Benz Center.
Fuel consumption is also increased by driv-
ing in cold weather, in stop-and-go traffic,
on short trips and in hilly country.
Drinking and driving
Pedals
Warning!
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 ac-
cident 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.
Warning!
G
Keep driver’s foot area clear at all times. Ob-
jects stored in this area may impair pedal
movement.

250 OperationDriving instructionsPower assistance
Brakes
Warning!
G
The brake system requires electrical energy
for operation.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its
limp-home (emergency operation) mode. In
such a case, the red brake warning lamp
(page 291) and warning messages in the
instrument cluster (
page 303) light up
while driving. To brake, the driver must then
apply significantly greater brake pedal pres-
sure and depress the pedal much further to
obtain the expected braking effect. If neces-
sary, apply full pressure to the brake pedal.
Brakes are only applied to the front wheels.
Stopping distance is increased! If there is a
malfunction in the SBC brake system, we
recommend that the vehicle be transported
with all wheels off the ground using flatbed
or appropriate wheel lift/dolly equipment. A
tow bar must be used if circumstances do
not permit the use of the recommended
towing methods and the vehicle requires
towing with all four wheels on the ground.
Towing the vehicle with all four wheels on
the ground is only permissible for distances
up to 30 miles (50 km) and at a speed not to
exceed 30 mph (50 km/h). For more infor-
mation, refer to "Towing the vehicle"
(page 348). For more information see
SBC brake system (
page 77).
With the engine not running, there is no
power assistance for the steering system. In
this case, it is important to keep in mind that
a considerably higher degree of effort is nec-
essary to steer the vehicle.
Warning!
G
After driving in heavy rain for some time
without applying the brakes or through wa-
ter 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 ef-
fect. 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.

251 Operation
Driving instructions
To help prevent brake disk corrosion after
driving on wet road surfaces (particularly
salted roads), it is advisable to brake the
vehicle with considerable force prior to
parking. The heat generated serves to dry
the brakes.
If your brake system is normally only sub-
jected to moderate loads, you should occa-
sionally test the effectiveness of the
brakes by applying above-normal braking
pressure at higher speeds. This will also
enhance the grip of the brake pads. If the parking brake is released and the
brake warning lamp in the instrument clus-
ter stays on, there is a malfunction in the
SBC brake system (
page 77) or 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 res-
ervoir.
Have the brake system inspected at an au-
thorized Mercedes-Benz Center immedi-
ately.
All checks and service work on the brake
system should be carried out by an autho-
rized Mercedes-Benz Center.
Only install brake pads and brake fluid rec-
ommended by Mercedes-Benz.
After hard braking, it is advisable to drive
on for some time, rather than immediately
parking, so that the air stream will cool
down the brakes faster.
It can also result in the brakes overheating,
thereby significantly reducing their effec-
tiveness. It may not be possible to stop the
vehicle in sufficient time to avoid an acci-
dent.!Be very careful not to endanger other
road users when you apply the brakes.
Refer to the description of the Brake
Assist System (BAS) (
page 74).
Warning!
G
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that
safe braking is substantially impaired. This
could result in an accident.
Be certain to read and observe the warning
notices on brake pad replacement
(page 305).!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 pre-
vent overheating of the brakes and re-
duces brake pad wear.

252 OperationDriving instructionsDriving off
Apply the 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 oper-
ating temperature has been reached.
When starting off on a slippery surface, do
not allow one drive wheel to spin for an ex-
tended 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
Tires
Tread wear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and be-
come visible at a tread depth of approxi-
mately
1⁄16
in (1.5 mm), at which point the
tire is considered worn and should be re-
placed.
!Set the parking brake whenever park-
ing or leaving the vehicle. In addition,
move selector lever to position P. In ad-
dition, when parking on hills, always set
the parking brake and turn front wheel
against curb.
Warning!
G
Do not park this vehicle in areas where com-
bustible 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.
To reduce the risk of personal injury as a re-
sult of vehicle movement, before turning off
the engine and leaving the vehicle always:

Keep right foot on brake pedal.


Firmly depress parking brake pedal.


Move the selector lever to positionP.


Slowly release brake pedal.


When parked on an incline, turn front
wheel towards the road curb.


Turn the key to starter switch position0
and remove, or press KEYLESS-GO*
start/stop button (vehicles with
KEYLESS-GO*).


Take the key or the SmartKey with
KEYLESS-GO* (if so equipped) with you
and lock vehicle when leaving.
Warning!
G
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possi-
ble damage to your vehicle has occurred,
you should turn on the hazard warning flash-
ers, carefully slow down, and drive with cau-
ti o n t o an a r ea wh ic h is a s a fe d is ta n c e fr o m
the road.
Inspect the tires and under the vehicle for
possible damage. If the vehicle or tires ap-
pear unsafe, have it towed to the nearest
Mercedes-Benz Center or tire dealer for re-
pairs.

253 Operation
Driving instructions
The tread wear indicator appears as a solid
band across the tread.
Specified tire pressures must be main-
tained. This applies particularly if the tires
are subjected to high loads (e.g. high
speeds, heavy loads, high ambient temper-
atures).
Aquaplaning
Depending on the depth of the water layer
on the road, aquaplaning may occur, even
at low speeds and with new tires. Reduce
vehicle speed, avoid track grooves in the
road and apply brakes cautiously in the
rain.
Tire traction
The safe speed on a wet, snow covered or
icy road is always lower than on a dry road.
You should pay particular attention to the
condition of the road whenever the outside
temperatures are close to the freezing
point.
Mercedes-Benz recommends M+S rated
radial-ply tires for the winter season for all
four wheels to insure normal balanced
handling characteristics. On packed snow,
they can reduce your stopping distance
compared to summer tires. Stopping dis-
tance, however, is still considerably great-
er than when the road is not covered with
snow or ice. Exercise appropriate caution.
Warning!
G
Do not allow your tires to wear down too far.
As tread depth approaches
1⁄16
in (1.5 mm),
the adhesion properties on a wet road are
sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely.
Warning!
G
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 or driving at high
speed with a flat tire will cause excessive
heat build-up and possibly a fire.
Warning!
G
If ice has formed on the road, tire traction
will be substantially reduced. Under such
weather conditions, drive, steer and brake
with extreme caution.

254 OperationDriving instructionsTire speed rating
Your vehicle is factory equipped with
"H"-rated tires, which have a speed rating
of 130 mph (210 km / h).
An electronic speed limiter prevents your
vehicle from exceeding the speed rating.
Regardless of the tire rating, local speed
limits should be obeyed. Use prudent driv-
ing speeds appropriate to prevailing condi-
tions.
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 or in
case you have a manual transmission, de-
clutch. Try to keep the vehicle under con-
trol by corrective steering action.Road salts and chemicals can adversely af-
fect braking efficiency. Increased pedal
force may become necessary to produce
the normal braking 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 en-
dangering other drivers on the road.
If the vehicle is parked after being driven
on salt-treated roads, the braking efficien-
cy should be tested as soon as possible af-
ter driving is resumed while observing the
safety rules in the previous paragraph.
Warning!
G
Even when permitted by law, never operate
a vehicle at speeds greater than the maxi-
mum speed rating of the tires.
Exceeding the maximum speed for which
tires are rated can lead to sudden tire fail-
ure, causing loss of vehicle control and re-
sulting in personal injury and possible death.
iFor more information on driving with
snow chains, see "Snow chains"
(page 274).
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.

Standing water
Passenger compartmentTraveling abroad
Abroad, there is a widely-spread
Mercedes-Benz service network at your
disposal. If you plan to travel into areas
which are not listed in the index of your
Mercedes-Benz Center directory, you
should request pertinent information from
your authorized Mercedes-Benz Center.
Warning!
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 the
engine running. Otherwise, deadly carbon
monoxide (CO) gases may enter vehicle in-
terior resulting in unconsciousness and
death.
To assure sufficient fresh air ventilation,
open a window slightly on the side of the ve-
hicle not facing the windWarning!
G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose. In-
dicated temperatures just above the freez-
ing point do not guarantee that the road
surface is free of ice.
!Do not drive through flooded areas or
water of unknown depth.
If you must drive through standing wa-
ter, drive slowly to prevent water from
entering the passenger compartment
or the engine compartment. Water in
these areas could cause damage to
electrical components or wiring of the
engine or transmission, or could result
in water being ingested by the engine
through the air intake causing severe
internal engine damage. Any such dam-
age is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G
Always fasten items being carried as secure-
ly as possible.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and cause injury
to vehicle occupants unless the items are
securely fastened in the vehicle.
The trunk is the preferred place to carry ob-
jects.
