Engine Remote Start (ERS) * –
introduction
ERS is a feature that makes it possible to remotely start the engine using the remote key tocool or heat the passenger compartment beforedriving.
The climate system will start using automatic set- tings. When the engine is started using ERS, it will run for a maximum of 15 minutes before automati-cally switching off again. After 2 ERS starts, theengine must be started in the normal way beforeERS can be used again.
NOTE
• Always adhere to applicable State, Prov- ince and/or Local laws regarding engineidling when using ERS.
• The service life of the remote key's bat-tery is affected by ERS use. If this featureis used frequently, the battery should bereplaced once a year, see Remote key –replacing the battery (p. 151).
WARNING
Keep the following in mind before using ERS:
• The vehicle should be in view.
• The vehicle should be unoccupied.
• The vehicle must not be parked indoors or in an enclosed area. Exhaust fumes areharmful to the health.

Connecting the jumper cables
If the 12-volt auxiliary battery to be used is in another vehicle, check that the vehicles are nottouching to prevent premature completion of acircuit. Be sure to follow jump starting instruc-tions provided for the other vehicle. To jump start your vehicle:
1. Switch off the ignition (set the ignition to mode 0, see Ignition modes (p. 74)).
2. First connect the red jumper cable to the auxiliary battery's positive (+) terminal (1).

Neutral: position NNo gear is engaged and the engine can be started with the gear selector in this position.Apply the parking brake if the vehicle is stationary with the gear selector in position N. In order to
move the gear selector from the N position, the
brake pedal must be depressed and the ignitionmust be in at least mode II.
Drive: position DD is the normal driving position. The car automat-
ically shifts between the various forward gears, based on the level of acceleration and speed.The car must be at a standstill when shifting from position R to position D.

Transmission – Geartronic
Geartronic allows you to manually shift among your vehicle's forward gears. The manual posi-tion ( +S–) can be selected at any time.
Geartronic: manual shifting (+S–)To shift gears manually, move the gear selector to the side from D toward
+S– . The +S– symbol in the instrument
panel will change from white to
orange and the number of the gear currently
being used (
1, 2, 3, etc.) will be displayed (see
the following illustration) 5
.
• To return to automatic shifting mode from +S–
, move the gear selector to the side
toward D.

While driving
•If you select the manual shifting position while driving, the gear that was being used inthe Drive position will also initially beselected in the manual shifting position.
• Move the gear selector forward (toward
+) to
shift to a higher gear or rearward (toward –)
to shift to a lower gear.
• If you hold the gear selector toward "
–", the
transmission will downshift one gear at atime and will utilize the braking power of theengine. If the current speed is too high forusing a lower gear, the downshift will notoccur until the speed has decreased enoughto allow the lower gear to be used.
• If you slow to a very low speed, the transmis-sion will automatically shift down.
Shiftlock: Neutral (N)
If the gear selector is in the
N position and the
vehicle has been stationary for at least 3 seconds (irrespective of whether the engine is running)then the gear selector is locked. In order to move the gear selector from N to
another gear position, the brake pedal must be depressed and the ignition must be in at least position II, see Ignition modes (p. 74).
Geartronic : steering wheel paddles *
In addition to the manual gearshift function using the gear selector, this option makes it possible tomanually shift gears from the steering wheel.
Steering-wheel mounted gear shift paddles
"– ": Shift down to a lower gear.
"+ ": Shift up to a higher gear.
In order to shift gears with the paddles, they have to first be activated. The gear selector can be
in either the D or S position. Activating the paddles:
• Pull either paddle toward the steering wheel and release it; the
D in the instrument panel
will change to the number of the gear cur- rently being used. Shifting gears:
• Pull the paddle toward the steering wheeland release it.
Deactivating the paddles:
• Hold the "
+" paddle for approximately
3 seconds.
NOTE
If the gear selector was in D when paddle
shifting was activated ( D changed to the
number of the gear being used), the transmis- sion will automatically revert to D after
approximately 5 seconds if the paddles are not used to shift gears. This will not occur:

Transmission – shiftlock override
If the vehicle cannot be driven, for example because of a dead battery, the gear selectormust be moved from the P position before the
vehicle can be moved 8
.
Shiftlock override
Lift away the rubber mat on the floor of the storage compartment behind the center con-sole to expose the small opening for overrid-ing the shiftlock system.
Insert the key blade into the opening. Press the key blade down as far as possible andkeep it held down.
Move the gear selector from the P position.
For information on the key blade, see Detachable key blade – general information(p. 149).

Brake pad inspection
On vehicles equipped with a jack *, the condition
of the brake pads can be checked by raising the vehicle (see Changing a wheel – removing wheel(p. 295) for information about using the jack andremoving a wheel) and performing a visualinspection of the brake pads.
WARNING
• If the vehicle has been driven immediately prior to a brake pad inspection, the wheelhub, brake components, etc., will be veryhot. Allow time for these components tocool before carrying out the inspection.
• Apply the parking brake and put the gear selector in the Park (
P) position.
• Block the wheels standing on the ground, use rigid wooden blocks or large stones.
WARNING
• Use the jack intended for the vehicle when changing a tire. For any other job,use stands to support the vehicle.
• The jack should be kept well-greased andclean, and should not be damaged.
• Be sure the jack is on a firm, level, non-slippery surface.
• No objects should be placed between thebase of jack and the ground, or betweenthe jack and the attachment bar on thevehicle.
• The jack must correctly engage the jackattachment.
• Never allow any part of your body to beextended under a vehicle supported by ajack.
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the engine is running. Neverlet the vehicle roll to a stop with the engineswitched off. If the power brakes are not working, considerably higher pressure will be required on the brakepedal to compensate for the lack of power assis-tance. This can happen for example when towingyour vehicle or if the engine is switched off whenthe vehicle is rolling. The brake pedal feels harderthan usual.
Water on brake discs and brake pads affects braking
Driving in rain and slush or passing through an automatic car wash can cause water to collect onthe brake discs and pads. This will cause a delayin braking effect when the pedal is depressed. Toavoid such a delay when the brakes are needed,depress the pedal occasionally when drivingthrough rain, slush, etc. This will remove the waterfrom the brakes. Check that brake applicationfeels normal. This should also be done afterwashing or starting in very damp or cold weather.
Severe strain on the brake systemThe brakes will be subject to severe strain whendriving in mountains or hilly areas, or when towinga trailer. Vehicle speed is usually slower, whichmeans that the cooling of the brakes is less effi-cient than when driving on level roads. To reducethe strain on the brakes, shift into a lower gearand let the engine help with the braking. Do notforget that if you are towing a trailer, the brakeswill be subjected to a greater than normal load.
Cleaning the brake discsCoatings of dirt and water on the brake discsmay result in delayed brake function. This delay isminimized by cleaning the brake linings. Cleaning the brake pads is advisable in wet weather, prior to long-term parking, and after thevehicle has been washed. Do this by braking gen-tly for a short period while the vehicle is moving.
