| UMTS network telephone (1900 to 2100 MHz) | 10 (PEP) | Roof center rear (standard roof antenna position) |
eff. = effective transmission output
PEP = maximum carrier power (Peak Envelope Power)
If transmitter/receiver units are installed with a higher output or with an antenna that differs from the items named above, the vehicle operating permit may be void.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
