Gate operator/Canadian programming Canadian radio-frequency laws require transmitter signals to “time-out” (or quit) after several seconds of transmission which may not be long enough for the integrated signal transmitter to pick up the signal during programming. Similar to this Canadian law, some U.S. gate operators are designed to “time-out” in the same manner. If you live in Canada or if you are having difficulties programming a gate operator (regardless of where you live) by using the programming procedures, replace step 4 with the following: X Step 4: Press and hold the signal

transmitter button (;, = or ?). Do not release this button until it has been successfully trained.

X While still holding down the signal

transmitter button (;, = or ?), “cycle” your hand-held remote control button B as follows: Press and hold button B for 2 seconds, then release it for 2 seconds, and again press and hold it for 2 seconds. Repeat this sequence on the hand-held remote control until the frequency signal has been learned. Upon successful training, indicator lamp : will flash slowly and then rapidly after several seconds.

X Proceed with programming step 5 and

step 6 to complete.

i Upon completion of programming the

integrated remote control, make sure you retain the hand-held remote control that came with the garage door opener, gate operator or other device. You may need it for use in other vehicles, for future programming of an integrated remote

Programming tips If you are having difficulty programming the integrated remote control, here are some helpful tips: RCheck the frequency of hand-held remote control A (typically located on the reverse side of the remote). The integrated remote control is compatible with radio-frequency devices operating between 280-390 MHz.

RPut a new battery in hand-held remote

control A. This will increase the likelihood of the hand-held remote control sending a stronger and more accurate signal to the integrated remote control.

RWhile performing step 3, hold hand-held

remote control A at different lengths and angles from the signal transmitter button (;, = or ?) you are programming. Attempt varying angles at the distance of 2
to 12 inches (5 to 30 cm) away or the same angle at varying distances.

RIf another hand-held remote control is available for the same device, try the programming steps again using that other hand-held remote control. Make sure new batteries are in the hand-held remote control before beginning the procedure.

RStraighten the antenna wire from the

garage door opener assembly. This may help improve transmitting and/or receiving signals.

throttle driving) and excessive engine speeds (no more than 2/3 of maximum rpm in each gear).

RVehicles with automatic transmission:

- Select C as the preferred shift program

(Y page 111) for the first 1 000 miles (1 500 km).

- Do not attempt to slow the vehicle down by shifting to a lower gear using the gear selector lever.

- Select gear ranges 3, 2 or 1

(Y page 111) only when driving at moderate speeds (for hill driving). - Avoid accelerating by kickdown. RVehicles with manual transmission:

Shift gears in a timely manner.

After 1 000 miles (1 500 km) you may gradually increase vehicle and engine speeds to the permissible maximum.

! Additional instructions for AMG vehicles: RDuring the first 1 000 miles (1 500 km),

do not exceed a speed of 85 mph (140 km/h).

RDuring this period, avoid engine speeds

above 4 500 rpm in each gear. RShift gears in a timely manner.

All of the above instructions, as may apply to your vehicle type, also apply when driving the first 1 000 miles (1 500 km) after the engine or the rear differential has been replaced. i Always obey applicable speed limits.

At the gas station Refueling G Warning! Gasoline is highly flammable and poisonous. It burns violently and can cause serious personal injury.

Tires and wheels Safety notes Contact an authorized Mercedes-Benz Center for information on tested and recommended rims and tires for summer and winter operation. They can also offer advice concerning tire service and purchase. G Warning! Replace rims or tires with the same designation, manufacturer and type as shown on the original part. For further information contact an authorized Mercedes-Benz Center. If incorrectly sized rims and tires are mounted, the wheel brakes or suspension components can be damaged. Also, the operating clearance of the wheels and the tires may no longer be correct. G Warning! Worn, old tires can cause accidents. If the tire tread is worn to minimum tread depth, or if the tires have sustained damage, replace them. When replacing rims, only use genuine Mercedes-Benz wheel bolts specified for the particular rim type. Failure to do so can result in the bolts loosening and possibly an accident. Retreaded tires are not tested or recommended by Mercedes-Benz, since previous damage cannot always be recognized on retreads. The operating safety of the vehicle cannot be assured when such tires are used. G Warning! If you feel a sudden significant vibration or ride disturbance, or you suspect that possible damage to your vehicle has occurred, you

Tires and wheels

229

should turn on the hazard warning flashers, carefully slow down, and drive with caution to an area which is a safe distance from the road. Inspect the tires and the vehicle underbody for possible damage. If the vehicle or tires appear unsafe, have the vehicle towed to the nearest authorized Mercedes-Benz Center or tire dealer for repairs. G Warning! Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You could lose control of the vehicle. Continued driving with a flat tire or driving at high speed with a flat tire will cause excessive heat build- up and possibly a fire.

Important guidelines ROnly use sets of tires and rims of the same

type and make.

RTires must be of the correct size for the rim. RBreak in new tires for approximately

60 miles (100 km) at moderate speeds.

RRegularly check the tires and rims for

damage. Dented or bent rims can cause tire inflation pressure loss and damage to the tire beads.

RIf the vehicle is heavily loaded, check tire inflation pressure and correct as required. RDo not allow your tires to wear down too far. Adhesion properties on wet roads are sharply reduced at tread depths of less than 1/8 in (3 mm).

RWhen replacing individual tires, you should mount new tires on the front wheels first (on vehicles with same-sized wheels all around).
