Checking trailer lamps *
Automatic checking
After a trailer is connected electrically, it is possi- ble to check that the trailer lamps are working viaan automatic lamp activation. The function helpsthe driver check that the trailer lamps are workingbefore starting off. The engine must be switched off to perform thecheck.
1. When a trailer is connected to the towing
bracket, the
Automatic Trailer Lamp
Check message is shown in the driver dis-
play.
2. Confirm the message by pressing the right- hand steering wheel keypad's O button.
> The lamp check starts.
3. Exit the car to check lamp functionality. > All trailer lamps start to flash - then thelamps are switched on one at a time.
4. Visually check that all lamps available on the trailer are operational.
5. After a moment, all lamps on the trailer flash again.
> The check is complete.
Switching off automatic checking
The automatic checking function can be switched off in the centre display. 1.Press
Settings in the top view.
2. Press
My CarLights and Lighting.
3. Deselect
Automatic Trailer Lamp Check.
Manual checking
If the automatic checking is switched off then it is possible to start the check manually. 1.Press
Settings in the top view. 2.
Press
My CarLights and Lighting.
3. Select
Manual Trailer Lamp Check.
> The lamp check starts. Exit the car to check lamp functionality.
Level control *The car's system for level control endeavours to maintain a constant height regardless of load (upto the maximum permissible weight). When thecar is stationary the rear of the car lowers slightly,which is normal.

Tread wear indicators on the tyres Tread wear indicators show the status of the tyre's tread depth.
A tread wear indicator is a narrow elevation across the longitudinal grooves of the tyre's treadpattern. On the side of the tyre are the lettersTWI (Tread Wear Indicator). When the tyre's treaddepth is down to 1.6 mm, the tread will be level inheight with the tread wear indicators. Change tonew tyres as soon as possible. Remember thattyres with little tread depth provide very poor gripin rain and snow.

•Tyres (p. 482)
Checking the tyre pressures Tyres with the correct air pressure increase driv- ing safety, save fuel and extend the service life ofthe tyres.
Tyre pressure decreases over time, this is a natu- ral phenomenon. Tyre pressure also variesdepending on ambient temperature. Inadequatetyre pressure increases fuel consumption, short-ens tyre lifespan and impairs the car's drivingcharacteristics. Driving on tyres with tyre pressurethat is too low could result in the tyres overheat-ing and being damaged. Tyre pressure affectstravelling comfort, road noise and driving charac-teristics.
Recommended tyre pressure
The tyre pressure label on the driver's side door pillar (between frame and rear door) shows which pressures the tyres should have at different loadsand speed conditions.
Improved fuel economy with ECO pressure
For a light load (max. 3 people) and a speed of up to 160 km/h (100 mph), the ECO pressurescan be chosen for optimum fuel economy. How-ever, the lower comfort pressures are recom-mended instead if optimum noise and travellingcomfort are desired.
Checking the air pressure1. Check the tyre pressures monthly. Carry out
the check on cold tyres, which means thatthe tyres should have the same temperatureas the outside temperature. After several fewkilometres of driving, the tyres warm up andthe pressure increases.
2. If necessary, inflate so that the air pressure corresponds with the approved tyre pressurein accordance with the tyre pressure label.
NOTE
• After a tyre has been inflated, always refit the dust cap in order to avoid damage tothe valve from gravel, dirt, etc.
• Only use plastic dust caps. Metal dustcaps can rust and become difficult tounscrew.

Dimension designation for wheel rim
Wheel and rim dimensions are designated in accordance with the examples in the tablebelow.
All wheel rims have a dimension designation, for example: 8.5Jx19x47.5.
8.5 Rim width in inches
J Rim flange profile
19 Rim diameter in inches
47,5 Off-set in mm (distance from wheel centre to wheel contact surface against the hub)
The car has an approval for the complete vehicle with certain combinations of wheel rims andtyres.

Designation of dimensionsAll tyres have a dimension designation, such as:255/40 R19 100 W.

40 Ratio between tyre wall height and tyre width (%)

100 Codes for the maximum permitted tyre load, tyre load index (LI)
W Speed rating for maximum permitted speed, speed rating (SS). (In this case 270 km/h (168 mph).)
Load indexEach tyre has a certain capacity to carry a load, a load index (LI). The car's weight determines theload capacity required of the tyres. The lowestpermitted load index is specified in a load indextable.
Speed ratingEach tyre can withstand a certain maximumspeed. Tyre speed rating, SS (Speed Symbol),must at least correspond with the car's topspeed. The table below shows the maximum per-mitted speed for each speed rating (SS). Theonly exception to these regulations is winter tyres3
, where a lower speed rating may be used.
If such a tyre is chosen, the car must not be driven faster than the speed rating of the tyre (forexample, class Q can be driven at a maximum of160 km/h (100 mph).) The top speed at whichthe car can be driven depends on road condi-tions, not the speed rating of the tyres.
NOTE
The maximum permitted speed is specified in the table.
Q 160 km/h (100 mph) (used only on win- ter tyres)
T 190 km/h (118 mph)
H 210 km/h (130 mph) V 240 km/h (149 mph)
W 270 km/h (168 mph) Y 300 km/h (186 mph)
3 Both those with metal studs and those without.
