Spare wheel
Spare wheel CLK 320 (except Sport Package)
Important!
The spare wheel rim is mounted with a full size tire of 
the same type as on the vehicle, 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.
In the case of a flat tire, you may temporarily use the 
spare wheel.
Do not operate vehicle with more than one spare wheel 
mounted.
Unidirectional tires must always be mounted with arrow 
on tire sidewall pointing in direction of vehicle forward 
movement.
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.For rim and tire specifications, refer to “Technical Data” 
(page 314).
Spare wheel CLK 320 (with Sport Package), 
CLK 430, CLK 55 AMG
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 (CLK 320 
with Sport Package: the tire size is 205/55 R 16 91 H), 
and is fully functional. However, the 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.
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.

If a tire constantly loses air, it should be inspected for 
damage.
The spare tire should be checked periodically for 
condition and inflation. Spare tire will age and become 
worn over time even if never used, and thus should be 
inspected and replaced when necessary.Battery
Important!
Battery replacement information:
The maintenance-free battery is located in the trunk 
under the trunk floor. 
The service life of the battery is dependent on its 
condition of charge. The battery should always be kept 
sufficiently charged, in order to last an optimum length 
of time.
Wa r n i n g !
Do not overinflate tires. Overinflating tires can 
result in sudden deflation (blowout) because they 
are more likely to become punctured or damaged 
by road debris, potholes etc.. Follow recommended 
inflation pressures.Do not overload the tires by exceeding the specified 
vehicle capacity weight (as indicated by the label 
on the driver’s door latch post). Overloading the 
tires can overheat them, possibly causing a 
blowout.
Wa r n i n g !
Failure to follow these instructions can result in 
severe injury or death.Never lean over batteries while connecting, you 
might get injured.Battery fluid contains sulfuric acid. Do not allow 
this fluid to come in contact with eyes, skin or 
clot hin g. In  cas e i t d oes , i mm ed ia tely  f lus h a f fected  
area with water and seek medical help if necessary.A battery will also produce hydrogen gas, which is 
flammable and explosive. Keep flames or sparks 
away from battery, avoid improper connection of 
jumper cables, smoking etc..
