Vehicle keys Included with your vehicle are 2 electronic keys with integrated radio frequency and infrared remote controls plus removable mechanical key. The locking tabs for the mechanical key portion of the two electronic keys are a different color to help distinguish it.

Warning! When leaving the vehicle, always remove the electronic key from the steering lock, and lock your vehicle. Do not leave children unattended in the vehicle, or with access to an unlocked vehicle. Unsupervised use of vehicle equipment may cause an accident and/or serious personal injury.

When using the mechanical key (2) for lock operations, it can be removed by sliding it out of the remote control. To do so, move locking tab (3) to the right and slide the mechanical key (2) in direction of arrow (4). The remote control transmitter is located in the electronic key. The infrared receivers are located in the door handles.

Obtaining replacement keys Your vehicle is equipped with a theft deterrent locking system requiring a special key manufacturing process. For security reasons, replacement keys can only be obtained from your authorized Mercedes-Benz Center.

Electronic key

P80.35-2031-26

The electronic key has an integrated radio frequency and infrared remote control, plus removable mechanical key. The remote control (1) operates all locks on the vehicle. The mechanical key (2) works only in the driver’s door, trunk, and glove box lock.

Power seats, front

Warning! Do not adjust the driver’s seat while driving. Adjusting the seat while driving could cause the driver to lose control of the vehicle. Never ride in a moving vehicle with the backrest reclined. Sitting in an excessively reclined position can be dangerous. You could slide under the seat belt in a collision. If you slide under it, the belt would apply force at the abdomen or neck. That could cause serious or even fatal injuries. The backrest and seat belt provide the best restraint when the wearer is in an upright position and the belt is properly positioned on the body. Never place hands under seat or near any moving parts while a seat is being adjusted.

Warning! When leaving the vehicle, always remove the electronic key from the steering lock, and lock your vehicle. The power seats can also be operated with the driver’s or passenger door open. Do not leave children unattended in the vehicle or with access to an unlocked vehicle. Unsupervised use of vehicle equipment may cause an accident and/or serious personal injury.

To operate the front power seat adjustment switches, turn electronic key in steering lock to position 1 or 2 (with the driver’s or passenger’s door open, the power seats can also be operated with the electronic key removed or in steering lock position 0).

safely. The position should be as far rearward as possible, consistent with ability to properly operate controls. Note: Do not move the front passenger seat completely forward if objects are stored in the parcel net in the front passenger side footwell. Items in the net may be damaged.

3 Seat cushion tilt

Press the switch in the direction of the arrow until your legs are lightly supported.

The slide switches are located in each door. We recommend to adjust the power seat in the following order:

1 Seat, up/down

Press the switch (up/down direction) until comfortable seating position with still sufficient headroom is reached.

2 Seat, fore/aft

Press the switch (fore/aft direction) until a comfortable seating position is reached that still allows you to reach the accelerator/brake pedal

4 Backrest tilt

Press the switch in the direction of the arrow until your arms are slightly angled when holding the steering wheel. 5 Head restraint

During seat adjustment, the head restraint is automatically adjusted based on seat (fore/aft) position to support the back of the head approximately at ear level. Please check the position of the head restraint to assure that it supports the back of the head approximately at ear level. The head restraint angle can also be adjusted manually.

Memory storing and recalling

Notes: Your vehicle is equipped with power head restraints, do not try to raise or lower them manually. Only minor personal adjustments, as described below, should then be required. For steering wheel adjustment, see page 73; inside rear view mirror, see page 74; exterior rear view mirrors, see page 75.

Caution! Do not remove head restraints except when mounting seat covers. For removal see page 46. Whenever restraints have been removed be sure to reinstall them before driving.

Storing Three sets of seat/head restraint positions may be programmed into memory. Together with the driver’s seat position you can store the exterior rear view mirror positions. After the seat/head restraint and exterior rear view mirrors are positioned, push memory button (6), release, and within 3 seconds push position button “1”. A second and third set of positions for the same seat/ head restraint and exterior rear view mirrors can be programmed into memory by pushing first memory button (6) and then “2”, respectively “3”.

Note: See page 75 for instructions on adjustment of mirrors.

44

Recalling To recall a seat/head restraint and exterior rear view mirror position, push and hold position button “1”, “2” or “3” until seat/head restraint and exterior rear view mirror movement has stopped. The seat/head restraint and exterior rear view mirror movement stops when the position button is released.

Caution! Do not operate the power seats using the memory button if the backrest is in an excessively reclined position. Doing so could cause damage to front or rear seats. First move the backrest to an upright position.

Synchronizing power seats and head restraints If the power supply was interrupted (battery disconnected or empty), the power seats and head restraints are no longer adjusted automatically. To resynchronize the adjustment feature, turn electronic key in steering lock to position 2, move the seat completely forward and the head restraint fully down, and hold respective buttons for approx. 2 seconds.

Important! Prior to operating the vehicle, the driver should adjust the seat height for proper vision as well as fore/aft placement and backrest angle to insure adequate control, reach, operation, and comfort. The head restraint should also be adjusted for proper height. See also airbag section on page 61 for proper seat positioning. In addition, also adjust the steering wheel to ensure adequate control, reach, operation, and comfort. Both the inside and outside rear view mirrors should be adjusted for adequate rearward vision. Fasten seat belts. Infants and small children should be seated in a properly secured restraint system that complies with U.S. Federal Motor Vehicle Safety Standards 213 and 225 and Canadian Motor Vehicle Safety Standards 213 and 210.2. All seat, head restraint, steering wheel, and rear view mirror adjustments as well as fastening of seat belts should be done before the vehicle is put into motion.

Warning! Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized BabySmartTM compatible child seat, which operates with the BabySmartTM system installed in the vehicle to deactivate the passenger side front airbag when it is properly installed. Otherwise they will be struck by the airbag when it inflates in a crash. If this happens, serious or fatal injury can result. According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seating positions. Infants and small children must ride in back seats and be seated in an appropriate infant or child restraint system, which is properly secured with the vehicle's seat belt or lower anchors, fully in accordance with the child seat manufacturer’s instructions. A child’s risk of serious or fatal injuries is significantly increased if the child restraints are not properly secured in the vehicle and the child is not properly secured in the child restraint.

Front head restraints

Warning! For your protection, drive only with properly positioned head restraints. Adjust head restraint to support the back of the head approximately at ear level. Do not drive the vehicle without the seat head restraints. Head restraints are intended to help reduce injuries during an accident.

Removal: Tilt the backrest rearward for easier removal of the front head restraints. Push button (1) up to bring the power adjustable head restraint to its highest position. Pull out head restraint completely with both hands.

Installation: Push button (1) of the power adjustable head restraint up for approximately 5 seconds. Insert the head restraint and push it down to the stop. Adjust head restraint to the desired position. For positioning of head restraints see also power seats, front on page 41, and head restraints, rear on page 48.

Roll bar and head restraints, rear The rear head restraints are integrated in the roll bar. The roll bar will be automatically raised in an accident or in a potentially dangerous driving situation. A ratchet noise can be heard when the roll bar is automatically raised. The roll bar can be lowered again after an automatic deployment by pressing the upper half of the roll bar switch (for at least 8 seconds) until the roll bar drive mechanism audibly engages. Then press the lower half of the switch to lower the roll bar. If the roll bar was raised using the switch, it will be automatically lowered when activating the soft top switch.

Warning! Raising or lowering of the roll bar could injure rear seated occupants. Before operating the roll bar switch make sure that the roll bar’s path is clear and no persons due to inattention are injured by the moving roll bar. For your own safety we recommend to drive with the roll bar raised, if • the outside temperature is below +5°F (-15°C). • the rear seats are occupied by passengers.

Before working on the vehicle, e.g. when changing wheels, the roll bar should be raised with the switch, and the electronic key should be removed from the steering lock, to prevent possible injury. In case of potential danger release the switch to immediately interrupt the operating procedure.
