WARNING
Keep vehicle doors and trunk locked and keep keys out of a child's reach. Unsupervised children could lock
themselves in an open trunk and risk injury. Children should be taught not to play in vehicles.
On hot days, the temperature in the trunk or vehicle interior can rise very quickly. Exposure of people to these
high temperatures for even a short period of time can cause heat-related injury or death. Small children are
particularly at risk.

When the backrest is returned to the upright position, check that it is properly locked in place. Return the head
restraints to the upright position.
Long loads should always be securely anchored to help avoid injury in the event of a sudden stop.
Always turn the engine off and apply the parking brake when loading/unloading the vehicle.

The headlights will be washed the first time the windshield is washed. Thereafter, the headlights will only be washed
once for every five times the windshield is washed within a 10-minute period.
Parking lights on
Optional Active Bi -Xenon® headlights will be washed once for every five times the windshield is washed. Normal
halogen headlights will not be washed.
CAUTION
Use ample washer fluid when washing the windshield. The windshield should be thoroughly wet when the wipers
are in operation.
NOTE
One headlight is washed at a time.

258 06 Maintenance and specifications
Wheels and tires
Inflating tires
The tire sealing system can be used to inflate the tires. To do so:
1. Park the car in a safe place.
2. The compressor should be switched off. Ensure that the on/off switch is in position 0 (the 0 side of the switch should
be pressed down).
3. Take out the electrical wire and hose.
4. Remove the valve cap from the tire's inflation valve and screw the hose connector onto the valve as tightly as
possible by hand.
5. Connect the electrical wire to the nearest 12-volt socket in the vehicle.
6. Start the vehicle's engine.
WARNING
The vehicle's engine should be running when the tire sealing system is used to avoid battery drain. Therefore, be
sure the vehicle is parked in a well ventilated place, or outdoors, before using the system.
Children should never be left unattended in the vehicle when the engine is running.
7. Check the tire's inflation pressure on the gauge. Switch off the compressor briefly to get a clear reading from the
pressure gauge.
8. Refer to the tables on pages 240 and 241
for the correct tire inflation pressure. If the tire needs to be inflated, start
the tire sealing system's compressor (press the on/off switch to position I ). If necessary, release air from the tire by
turning the air release knob counterclockwise.
CAUTION
The compressor should not be used for more than 10 minutes at a time to avoid overheating.
9. Turn off the compressor (press the on/off switch to position 0) when the correct inflation pressure has been reached.
10. Unscrew the hose from the tire's inflation valve and reinstall the valve cap.
11. Disconnect the electrical wire from the 12-volt socket.
