G
Do not place heavy or fragile objects, or ob-
jects having sharp edges, in the parcel net.
In an accident, during hard braking or sud-
den maneuvers, they could be thrown 
around inside the vehicle, and cause injury 
to vehicle occupants.
Warning!
G
The shelf behind the roll bars should not be 
used to carry objects. This will prevent such 
objects from being thrown around and injur-
ing vehicle occupants during an accident or 
sudden maneuver.

Telephone*
Radio transmitters, such as a portable tele-
phone or a citizens band unit, should only 
be used inside the vehicle if they are con-
nected to an antenna that is installed on 
the outside of the vehicle.
The external antenna must be approved by 
Mercedes-Benz. Please contact an autho-
rized Mercedes-Benz Center for informa-
tion on the installation of an approved 
external antenna. Refer to the radio trans-
mitter operation instructions regarding use 
of an external antenna.
Warning!
G
Never touch the heating element or sides of 
the cigarette lighter; they are extremely hot. 
Hold the knob only.
When leaving the vehicle, always remove the 
key from the steering lock, and lock your 
vehicle. Do not leave children unattended in 
the vehicle, or with access to an unlocked 
vehicle. Unsupervised use of vehicle equip-
ment may cause an accident and/or serious 
personal injury.iThe cigarette lighter socket can be 
used to accommodate electrical acces-
sories up to a maximum 85 W.
Warning!
G
Never operate radio transmitters equipped 
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna) 
from inside the vehicle while the engine is 
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or serious

164 OperationDriving instructionsVehicles with Sport Package*
Your vehicle is factory equipped with 
“Y”-rated tires, which have a speed rating 
of 186 mph (300 km / h).
Despite of the tire speed rating, local 
speed limits should be obeyed. Use pru-
dent driving speeds appropriate to prevail-
ing conditions.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 positionN or de-
clutch in case of manual transmission. Try 
to keep the vehicle under control by cor-
rective steering action.
Road salts and chemicals can adversely af-
fect 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. Be very careful 
that you carry out these braking maneu-
vers without endangering any other road 
users.
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.
iInformation on driving with snow 
chains (
page 184).
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.
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 wind.

Pull out the oil dipstick again after 
approximately 3 seconds.
The oil level is acceptable when it 
leaves a line between the upper and 
lower marks of the dipstick.
For adding oil (
page 175).
See “Practical hints” (
page 200) if the 
low engine oil level warning lamp in the in-
strument cluster lights up.You can check the engine oil level on the

181 Operation
Tires and wheels
Life of tire
The service life of a tire is dependent upon 
varying factors including but not limited to:
Driving style
Tire pressure
Distance driven
Direction of rotation
Unidirectional tires offer added advantag-
es, such as better aquaplaning perfor-
mance. To benefit, however, you must 
ensure that the tires rotate in the direction 
specified.
An arrow on the sidewall indicates the in-
tended direction of tire rotation.Checking tire inflation pressureCorrect the tire pressure only when tires 
are cold.
Regularly check your tire pressure at inter-
vals of no more than 14 days. 
If the tires are warm, you should only cor-
rect the tire pressure if it is too low for cur-
rent operating conditions.
A table on the fuel filler flap lists the spec-
ified tire inflation pressures for warm and 
cold tires as well as for various operating 
conditions.
Warning!
G
Tires and spare tire should be replaced after 
six years, regardless of the remaining tread.!Keep unmounted tires in a cool, dry 
place with as little exposure to light as 
possible. Protect tires from contact 
with oil, grease and gasoline.
Warning!
G
If the tire pressure repeatedly drops:
Check the tires for punctures from for-
eign objects.
Check to see whether air is leaking from 
the valves or from around the rim.
iThe pressures listed for light loads are 
minimum values offering high driving 
comfort.
Increased inflation pressures listed for 
heavier loads may also be used for light 
loads. These higher pressures produce 
favorable handling characteristics. The 
ride of the vehicle, however, will be 
somewhat harder. Never exceed the 
max. values or inflate tires below the 
min. values listed in the fuel filler flap.

192 OperationVehicle careHeadliner
Clean with soft bristle brush, or use a 
dry-shampoo cleaner in case of excessive 
dirt.
Seat belts
The webbing must not be treated with 
chemical cleaning agents. Use only clear, 
lukewarm water and soap. Do not dry the 
webbing at temperatures above 176°F 
(80°C) or in direct sunlight.Upholstery
Using aftermarket seat covers or wearing 
clothing that have the tendency to give off 
coloring (e.g. when wet, etc.) may cause 
the upholstery to become permanently dis-
colored. By lining the seats with a proper 
intermediate cover, contact-discoloration 
will be prevented.
Leather upholstery
Wipe leather upholstery with a damp cloth 
and dry thoroughly or clean with 
Mercedes-Benz approved Leather Care. 
Exercise particular care when cleaning per-
forated leather as its underside should not 
become wet.Cloth upholstery
Clean with soft bristle brush, or use a 
dry-shampoo cleaner in case of excessive 
dirt.
Plastic and rubber parts
Do not use oil or wax on these parts.Warning!
G
Do not bleach or dye seat belts as this may 
severely weaken them. In a crash they may 
not be able to provide adequate protection.
