cluster displayPractical hints Car care Index Roadside Assistance button •
Located below the center armrest cover is the Roadside 
Assistance button•. Pressing and holding the 
button (for longer than 2 seconds), will initiate a call to 
a Mercedes-Benz Roadside Assistance dispatcher. The 
button will flash while the call is in progress. The 
Tele Aid system will transmit data generating the 
vehicle identification number, model, color and location 
(subject to availability of cellular and GPS signals).
A voice connection between the Roadside Assistance 
dispatcher and the occupants of the vehicle will be 
established. The nature of the need for assistance can 
then be described. The Mercedes-Benz Roadside assistance dispatcher will 
either dispatch a qualified Mercedes-Benz technician or 
arrange to tow your vehicle to the nearest 
Mercedes-Benz Center. For services such as labor and/
or towing charges may apply. Refer to the Roadside 
Assistance manual for more information. 
These programs are only available in the USA:
•Sign and Drive services: Services such as jump start, 
a few gallons of fuel or the replacement of a flat tire 
with the vehicle spare tire are obtainable,
•Remote Vehicle Diagnostics: This function permits 
the Mercedes-Benz Roadside Assistance dispatcher 
to download malfunction codes and actual vehicle 
data.
Notes:
The indicator lamp in the Roadside Assistance 
button• remains illuminated in red for 
approximately 10 seconds during the system self-check 
after turning key in steering lock to position 2 (together 
with the “SOS” button and the Information 
button¡).
Wa r n i n g !
If you feel at any way in jeopardy when in the 
vehicle (e.g. smoke or fire in the vehicle, vehicle in 
a dangerous road location), please do not wait for 
voice contact after you have pressed the emergency 
button. Carefully leave the vehicle and move to a 
safe location. The Response Center will 
automatically contact local emergency officials 
with the vehicle’s approximate location if they 
receive an automatic “SOS” signal and cannot make 
voice contact with the vehicle occupants.

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,
•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. 

161 Driving instructions
Te ch n i c a l
data Instruments 
and controlsOperationDrivingInstrument 
cluster displayPractical hints Car care IndexSpecified tire pressures must be maintained. This 
applies particularly if the tires are subjected to high 
loads (e.g. high speeds, heavy loads, high ambient 
temperatures).
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.
Wa r n i n 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.
Wa r n i n 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.

Rotating wheels
Wheel rotation applies only when winter tires are 
mounted on all four wheels.
The wheels can be rotated according to the degree of 
tire wear while retaining the same direction of travel.
Rotating, however, should be carried out as 
recommended by the tire manufacturer, before the 
characteristic tire wear pattern (shoulder wear on front 
wheels and tread center wear on rear wheels) becomes 
visible, as otherwise the driving properties deteriorate.
Important!
Unidirectional tires must always be mounted with arrow 
on tire sidewall pointing in direction of vehicle forward 
movement.Notes:
Thoroughly clean the inner side of the wheels any time 
you rotate the wheels or wash the vehicle underside.
The use of retread tires is not recommended. Retread 
tires may adversely affect the handling characteristics 
and safety of the vehicle.
Dented or bent rims can cause tire pressure loss and 
damage to the tire beads. For this reason, check rims for 
damage at regular intervals. The rim flanges must be 
checked for wear before a tire is mounted. Remove 
burrs, if any.
Check and ensure proper tire inflation pressure after 
rotating the wheels. For tire inflation pressure see 
page 219.

The spare wheel rim size is 4 
1/2 B x 15 H 2 with 
inflatable, collapsible tire, size 165-15 89 P.
SLK 320:
The spare wheel rim size is 4 
1/2 B x 16 H 2 with 
inflatable, collapsible tire, size 165/70-16 92 P.
You should inflate the spare tire using the supplied air 
pump.
Note:
The model SLK 32 AMG is equipped with TIREFIT, 
see page 214.In the case of a flat tire, you may temporarily use the 
spare wheel, while 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 
collapsible spare wheel / tire mounted.
For additional information, see page 261.

Important!
For ease of handling and proper unfolding of tire during 
its inflation when installing spare wheel with 
collapsible tire, first mount the spare wheel, then inflate 
the tire.
10. Clean contact surfaces of wheel and wheel hub. 
Install wheel on wheel hub. Insert proper wheel 
bolts and tighten them snugly.
Unscrew the alignment pin (4) to install the last 
wheel bolt.
11. Inflate collapsible spare tire. (See next page for 
detailed instructions).Important!
When installing spare wheel with collapsible tire, make 
certain to use the correct wheel bolts, supplied in the 
vehicle tool kit.
To avoid paint damage, place wheel flat against hub and 
hold it there while installing first wheel bolt.
12. Lower vehicle. Remove jack and insert jack tube 
cover.
