To signal minor directional changes, such as changing
lanes on a highway, move combination switch to the
point of resistance only and hold it there.
To operate the turn signals continuously, move the
combination switch past the point of resistance (up or
down). The switch is automatically canceled when the
steering wheel is turned to a large enough degree.
Turn signal failure
If one of the turn signals fails, the turn signal indicator
system f lashes and sounds at a faster than normal rate.

Winter driving
Have your vehicle winterized at your authorized
Mercedes-Benz Center before the onset of winter.
•Change the engine oil if the engine contains an oil
which is not approved for winter operation. For
viscosity (SAE/CCMC class) and filling quantity, see
page 317.
•Check engine coolant anticorrosion/antifreeze
concentration.
•Additive for the windshield washer and headlamp
cleaning system: Add MB Concentrate “S” to a
premixed windshield washer solvent/antifreeze
which is formulated for below freezing temperatures
see page 259.
•Test battery: Battery capacity drops with decreasing
ambient temperature. A well charged battery helps
to ensure that the engine can be started, even at low
ambient temperatures.
•Tires: We recommend M+S rated radial-ply tires on
all four wheels for the winter season. Observe
permissible maximum speed for M+S rated
radial-ply tires and the legal speed limit.In winter operation, the maximum effectiveness of the
antilock brake system (ABS) or of the electronic stability
program (ESP) can only be achieved with M+S rated
radial-ply tires and / or snow chains recommended by
Mercedes-Benz. Snow chains maximize performance.
For driving instructions with snow chains, see page 210.
Deep water
Caution!
Do not drive t hrou gh f lood ed a rea s or water of u nk nown
depth.
If you must drive through deep water, drive slowly to
prevent water from entering the engine compartment or
passenger compartment, being ingested by the air
intake, possibly causing damage to electrical
components or wiring, to engine or transmission that is
not covered by the Mercedes-Benz Limited Warranty.
Block heater (Canada only)
The engine is equipped with a block heater.
The electrical cable may be installed at your authorized
Mercedes-Benz Center.

To cancel the cruise control, brief ly push lever to
position 3.
When you step on the brake pedal or the vehicle
speed drops below approx. 25 mph (40 km/h), for
example when driving upgrade, the cruise control
will be canceled.
If the cruise control cancels by itself and remains
inoperative until the engine is restarted, have the
system checked at your authorized Mercedes-Benz
Center as soon as possible.
4Resume
If the lever is briefly pushed to position 4 when
driving at a speed exceeding approx. 25 mph
(40 km/h), the vehicle resumes the speed which
was set prior to the cancellation of the cruise
control. The last memorized speed is canceled when
the electronic key in the steering lock is turned to
position 1 or 0.Important!
Moving gear selector lever to position “N” switches the
cruise control off.
Wa r n i n g !
Only use the cruise control if the traffic and
weather conditions make it advisable to travel at a
steady speed.• The use of cruise control can be dangerous on
winding roads or in heavy traffic because
conditions do not allow safe driving at a steady
speed.
• The use of cruise control can be dangerous on
slippery roads. Rapid changes in tire adhesion
can result in wheel spin and loss of control.The “Resume” function should only be operated if
the driver is fully aware of the previously set speed
and wishes to resume this particular preset speed.

The jack is designed exclusively for jacking up the
veh icle at th e jack tu bes bu ilt into eit her side of th e
vehicle. To help avoid personal injury, use the jack
only to lift the vehicle during a wheel change.
Never get beneath the vehicle while it is supported
by t he jack. Keep hands and feet away from th e area
under the lifted vehicle. Always firmly set parking
brake and block wheels before raising vehicle with
jack.Do not disengage parki ng brake wh ile th e vehi cle i s

when in use, especially on hills. Always try to use
the jack on level surface. Be sure that the jack arm
is fully inserted in the jack tube. Always lower the
vehicle onto sufficient capacity jackstands before
working under the vehicle.

Important!
The spare wheel rim size is 7
1/2J x 17 H 2.
The spare wheel rim is mounted with a full size tire of
the same type as on the vehicle’s front axle, and is fully
functional. However, that spare wheel rim is weight
optimized and has a limited service life of 12 000 miles
(20 000 km) use before a standard wheel rim must
replace it.
If the arrow on tire side wall does not point in direction
of vehicle forward movement when using the spare
wheel, observe the following restriction:
•Drive to the nearest tire repair facility as soon as
possible.
In the case of a rear axle f lat tire, you may temporarily
use the spare wheel, when observing the following
restrictions:
•Do not exceed vehicle speed of 50 mph (80 km/h)
•Drive to the nearest tire repair facility to have the
flat tire repaired or replaced as appropriate.Do not operate vehicle with more than one spare wheel
mounted.
Unid irectional tires must a lways be mou nted w it h a rrow
on tire sidewall pointing in direction of vehicle forward
movement.
For rim and tire specifications, refer to “Technical Data”
(page 314).
Wa r n i n g !
The spare wheel rim is for temporary use only. Use
for over a total of 12 000 miles (20 000 km)
(aggregate of all uses) may cause wheel rim failure
leading to an accident and possible injuries.The dimensions of the spare wheel are different
from those of the road wheels for the rear axle. As a
result, the vehicle handling characteristics change
when driving with a spare wheel mounted on the
rear axle.The spare wheel should only be used temporarily,
and replaced with a regular road wheel as quick as
possible.

Changing wheelsMove vehicle to a level area which is a safe distance
from the roadway.
1. Set parking brake and turn on hazard warning
flasher.
2. Move selector lever to position “P” and turn off
engine.
3. Prevent vehicle from rolling away by blocking
wheels with wheel chocks (not supplied with
vehicle) or sizable wood block or stone. When
changing a wheel on a hill, place chocks on the
downhill side blocking both wheels of the other
axl e. On a l evel road, pl ace one ch ock in front of a nd
one behind the wheel that is diagonally opposite to
the wheel being changed.

cluster displayPractical hintsCar care Index Tire inflation pressure
A table (see fuel filler f lap) lists the tire inflation
pressures specified for Mercedes-Benz recommended
tires as well as for the varying operating conditions.
Important!
Tire pressure changes by approx. 1.5 psi (0.1 bar) per
18°F (10°C) of air temperature change. Keep this in
mind when checking tire pressure inside a garage –
especially in the winter.
Example:
If garage temperature = approx. +68°F (+20°C) and
ambient temperature = approx. +32°F (0°C) then the
adjusted air pressure = specified air pressure +3 psi
(+0.2 bar).Tire pressures listed for light loads are minimum values
offering high driving comfort. Increased inflation
pressures for heavy loads produce favorable handling
characteristics with lighter loads and are perfectly
permissible. The ride of the vehicle, however, will
become somewhat harder.
Tire temperature and pressure increase with the vehicle
speed. Tire pressure should therefore only be checked
and corrected on cold tires. Correct tire pressure in
warm tires only if pressure has dropped below the
pressure listed in the table and the respective operating
conditions are taken into consideration.
An underinf lated tire due to a slow leak (e.g. due to a
nail in the tire) may cause damage such as tread
separation, bulging etc.. Regular tire pressure checks
(including the spare tire) at intervals of no more than
14 days are therefore essential.
