side.
At the same time pull the key blade
straight out backwards.
Insert a 3 mm slot screwdriver in the
hole behind the spring-loaded catch and gently prize the remote control key up.
NOTE
Turn the remote control key over with the buttons facing up, this is to avoid the bat-teries falling out when it is opened.
IMPORTANT
Avoid touching new batteries and their contact surfaces with your fingers as thismay impair their function.
Battery replacementClosely study how the battery/batteries are secured on the inside of the cover,with regard to their ( +) and ( –) sides.
Remove control key (1 battery)1. Carefully prize out the battery.
2. Install a new one with the ( +) side down.
PCC* (2 batteries)1. Carefully prize out the batteries.

Remote start (ERS)*
Remote start (ERS – Engine Remote Start) means that the car's engine can be startedremotely using the remote control key or thePCC key. This is so that the passenger com-partment can be warmed up/cooled downbefore departure. The climate control system and audio system start with the same settings that were in usewhen the car was parked. An ERS-started engine is activated for a maximum of 15 minutes, then it is switchedoff. After two ERS-activations the enginemust be started in the normal way beforeERS can be re-used. The optional ERS function is available on most cars with automatic gearbox.
NOTE
The service life of the remote control key's battery is affected by the ERS function. Inthe event of frequent use of ERS the bat-tery should therefore be changed once peryear, see Remote control key/PCC -replacing the battery (p. 158).
NOTE
Follow local/national rules/regulations on idling.
WARNING
To remote-start the engine, the following criteria must be met:
• The car must be supervised.
• There must be no people or animals inside the car.
• The car must not be parked in aclosed, unventilated area - the exhaustgases may seriously injure humansand animals.

IMPORTANT
After the fuel mixture in the tank has been changed an adaptation should be made bydriving at an even speed for about 15minutes.
If the battery has been discharged or discon- nected then a slightly longer period of drivingis required for the adaptation as the memoryfor the electronics has been cleared.

Jump starting with battery
If the starter battery (p. 361) is discharged then the car can be started with current fromanother battery.
When jump starting the car, the following steps are recommended to avoid short cir-cuits or other damage:
1. Insert the remote control key in key posi-
tion 0 (p. 70).
2. Check that the donor battery has a volt- age of 12 V.
3. If the donor battery is installed in another car - switch off the donor car's engine and make sure that the two cars do nottouch each other. 4. Connect one of the red jump lead's
clamps to the donor battery's positiveterminal (1).
IMPORTANT
Connect the start cable carefully to avoid short circuits with other components in theengine compartment.
5. Open the clips on the front cover of thebattery in your car and remove the cover, see Starter battery - replacement (p.363).
6. Connect the red jump lead's other clamp onto the car's positive terminal (2).
7. Connect one of the black jump lead's clamps to the donor battery's negativeterminal (3).
8. Connect the other clamp to a grounding point, e.g. right-hand engine mounting atthe top, the outer screw head (4).
9. Check that the jump lead clamps are affixed securely so that there are nosparks during the starting procedure.
10. Start the engine of the "donor car" and allow it to run a few minutes at a speedslightly higher than idleapprox. 1500 rpm.
