Emergency Spare Wheel
Notes on the Emergency Spare Wheel
Risk of accident caused by incorrect wheel and tire dimensions.
The wheel or tire sizes and the tire type of the emergency spare wheel or spare wheel and the wheel to be replaced may differ. The emergency spare wheel or spare wheel can significantly impair driving characteristics of the vehicle.
To prevent hazardous situations:
- Drive carefully.
- Never install more than one emergency spare wheel or spare wheel that differs in size.
- Only use an emergency spare wheel or spare wheel briefly.
- Do not deactivate ESP®.
- Have the emergency spare wheel or spare wheel of a different size replaced at the nearest qualified specialist workshop. The new wheel must have the correct dimensions.
The emergency spare wheel is secured in the emergency spare wheel bag in the trunk.
Observe the following notes on installing an emergency spare wheel:
- The maximum permissible speed with an emergency spare wheel installed is 50 mph (80 km/h).
- Do not install the emergency spare wheel with snow chains.
- Replace the emergency spare wheel after six years at the latest, regardless of wear.
- Use the wheel bolts that are included with the emergency spare wheel.
- Check the tire pressure of the emergency spare wheel installed. Correct the pressure as necessary.
The specified tire pressure is stated on the label of the emergency spare wheel.
Vehicles with a tire pressure loss warning system: if an emergency spare wheel is installed, the tire pressure loss warning system cannot function reliably. Only restart the system again when the emergency spare wheel has been replaced with a new wheel.
Vehicles with a tire pressure monitoring system: if an emergency spare wheel is installed, the tire pressure monitoring system cannot function reliably. For a few minutes after an emergency spare wheel is installed, the system may still display the tire pressure of the removed wheel. Only restart the system again when the emergency spare wheel has been replaced with a new wheel.

Notes on technical data
NOTE Mercedes-AMG vehicles
- Observe the notes in the Supplement. You could otherwise fail to recognize dangers.
The data stated only applies to vehicles with standard equipment. You can obtain further information from an authorized Mercedes-Benz Cen-ter.
Notes on installing two-way radios
Risk of accident due to improper work on two-way radios If two-way radios are manipulated or retrofit-ted incorrectly, the electromagnetic radiation from the two-way radios can interfere with the vehicle electronics and jeopardize the operating safety of the vehicle.
- You should have all work on electrical and electronic components carried out at a qualified specialist workshop.
WARNINGRisk of accident due to improper operation of two-way radios
If you use two-way radios in the vehicle improperly, their electromagnetic radiation can disrupt the vehicle’s electronics. This is the case in the following situations, in particular:
- The two-way radio is not connected to an exterior antenna.
- The exterior antenna is installed incorrectly or is not a low-reflection antenna.
This could jeopardize the operating safety of the vehicle.
- Has the low-reflection exterior antenna been installed at a qualified specialist workshop?
- When operating two-way radios in the vehicle, always connect them to the low-reflection exterior antenna.
Invalidation of the operating permit due to failure to comply with the instructions for installation and use
The operating permit may be invalidated if the instructions for the installation and use of two-way radios are not observed.
- Only use approved frequency bands.
- Observe the maximum permissible output power in these frequency bands.
- Only use approved antenna positions.
- Front roof area
- Rear roof area
- Rear fenders
- Trunk lid
On vehicles with a panoramic sliding sunroof, installing an antenna in the front or rear roof area is not permitted. On the rear fenders, it is recommended that you install the antenna on the side of the vehicle closest to the center of the road. Use Technical Specification ISO/TS 21609 (Road Vehicles – “EMC guidelines for installation of aftermarket radio frequency transmitting equipment”) when retrofitting two-way radios. Comply with the legal requirements for detachable parts.
If your vehicle has two-way radio equipment installed, use the power supply and antenna connectors provided in the pre-installation. Observe the manufacturer’s supplements when installing.
The two-way radio transmission output
The maximum transmission output (PEAK) at the base of the antenna must not exceed the values in the following table.
Frequency band and maximum transmission output
|Frequency band||Maximum transmission output|
|Short wave 3 – 54 MHz||100 W|
|4‑m‑ frequency band 74 – 88 MHz||30 W|
|2‑m‑ frequency band 144 – 174 MHz||50 W|
|Terrestrial Trunked Radio (TETRA)
380 – 460 MHz
|70‑cm‑ frequency band
420 – 450 MHz
|Two-way radio (2G/3G/4G)||10 W|
The following can be used in the vehicle without restrictions:
- two-way radios with a maximum transmission output of up to 100 mW
- RF transmitters with transmitter frequencies in the 380 – 410 MHz frequency band and a maximum transmission output of up to 2 W (TETRA)
- mobile phones (2G/3G/4G)
There are no restrictions when positioning the antenna on the outside of the vehicle for the following frequency bands:
- Terrestrial Trunked Radio (TETRA)
- 70‑cm‑ frequency band
