from its holder. For vehicles with a swivelling front seat, the retainer with the fire extinguisher is located at the side of the seat base.
Please read the instructions on the fire extinguisher carefully and familiarise yourself with its operation. Have the fire extinguisher refilled after each use and checked every one to two years, otherwise it may fail in an emergency.
Observe the legal requirements of the country in which you are currently driving.
Removing the warning triangle

Check the expiry date on the first-aid kit at least once a year. Replace any expired or missing contents.
Observe the legal requirements of the country in which you are currently driving.
QR codes for rescue card
The QR code stickers are affixed to the B-pillar on the driver's and co-driver's side. In the event of an accident, emergency services can use the QR code to quickly determine the corresponding rescue card for your vehicle. The current rescue card contains, in compact form, the most important information about your vehicle e.g. the routing of electric cables.
Further information can be obtained at Mercedes-Benz homepage - rescue card.
Starting assistance and charging the 12 V battery
Only have starting assistance provided by a qualified specialist workshop, e.g. a Mercedes-Benz Service Centre.
Only have the battery charged at a qualified specialist workshop, e.g. a Mercedes-Benz Service Centre.
Notes on electrical fuses
NOTE Electrical fuses
Observe the information in the supplement. You may otherwise fail to recognise dangers.
The fuse allocation chart and the information on the fuses can be found in the "Fuse allocation chart" Supplement.
Notes on flat tyres
WARNING Risk of accident due to a flat tyre
A flat tyre affects the driving characteristics of the vehicle.
Do not drive with a flat tyre.
Replace the flat tyre with the emergency spare wheel or spare wheel. Alternatively, consult a qualified specialist workshop.
You will find a sticker with the Mercedes-Benz Service24h telephone number on the B-pillar on the driver's side, for example.
For vehicles with a spare wheel, information in the event of a flat tyre can be found under "Wheels and tyres" More.
Permissible towing methods
In the event of a breakdown, Mercedes-Benz recommends that you have the vehicle transported instead of towed.
When towing away, use a towing rope or a tow bar with both axles on the ground.
If you notice that the vehicle has lost coolant, the vehicle must be towed away with a raised front axle or transported.
WARNING Risk of accident due to limited safety-related functions during the towing process
Safety-related functions are limited or no longer available in the following situations:
the ignition is switched off.
the brake system or power steering system is malfunctioning.
the energy supply or the on-board electrical system is malfunctioning.
When your vehicle is then towed away, significantly more effort may be required to steer and brake than is normally required.
Use a tow bar.
Make sure that the steering wheel can move freely before towing the vehicle away.
WARNING Risk of accident due to towing away a vehicle that is too heavy
If the vehicle being tow started or towed away is heavier than the permissible gross weight of your vehicle, the following situations may arise:
The towing eye may become detached.
The vehicle/trailer combination may even tip over.
Before tow starting or towing away a vehicle, check that it does not exceed the permissible gross weight.
Details on the permissible gross vehicle weight of your vehicle can be found on the vehicle identification plate More.
NOTE Damage due to incorrect connection of the tow bar or improper use of the towing device
Only connect the tow rope or tow bar to the towing eyes.
Do not use the towing eyes to recover a vehicle.
NOTE Damage due to pulling force being too high
Pulling away abruptly can damage the vehicles if the tractive forces are too high.
Pull away as straight, slowly and smoothly as possible.
NOTE Damage due to improper towing with a tow rope
If you ignore safety and protective measures when towing with a tow rope, this can result in damage to the vehicle.
Observe the following points:
Secure the tow rope on the same side on both vehicles.
Secure the tow rope to the towing eyes.
Do not exceed the legally prescribed length of the tow rope.
Mark the tow rope in the middle, e.g. with a white cloth (30 x 30 cm). This will make other road users aware that a vehicle is being towed.
During the journey, observe the brake lamps of the towing vehicle and maintain the distance so that the tow rope does not sag.
Do not use steel cables or chains to tow your vehicle.
NOTE Damage due to towing the vehicle at too high a speed or too far
Towing the vehicle at too high a speed or too far can damage the drivetrain.
Do not exceed a towing speed of 50 km/h.
Do not exceed a towing distance of 50 km.
NOTE Damage to the drivetrain due to insufficient cooling
If the cooling system is damaged, towing the vehicle can damage the drivetrain.
Have the vehicle towed with the front axle raised or have it transported.
NOTE Damage to the drivetrain due to unauthorised towing of the vehicle
Towing the vehicle backwards is not permitted as this can damage the drivetrain.
Only tow the vehicle forwards.
NOTE Damage from automatic braking
When Active Brake Assist, Active Distance Assist DISTRONIC or the HOLD function are activated, the vehicle brakes autonomously in certain situations.
To avoid damage to the vehicle, deactivate these systems in the following or similar situations:
During towing
In a car wash
NOTE Damage to the transmission when towing due to shifting into transmission position 
If you open the driver's or co-driver door when towing, the transmission can shift into position and become damaged.
Shift the automatic transmission to position 
.
. Do not open any doors during the towing process.
 Both axles on the ground |  Front axle raised |
|---|---|
Yes, no further than 50 km at 50 km/h | Yes, no further than 50 km at 50 km/h |
If the transmission cannot be shifted to position , have the vehicle transported More. A towing vehicle with lifting equipment is required for vehicle transport.
