2003 Mercedes-benz C Class Coupe Owners Manual

Shifting into optimal gear range 왘 Press and hold the gear selector lever

in the D– direction.

The transmission will automatically select the gear range suited for optimal accelera- tion and deceleration. This will involve shifting down one or more gears.

One-touch gearshifting

Even with an automatic transmission you can change the gears yourself when the selector lever is in position D.

Downshifting 왘 Briefly press the selector lever to the

left in the D– direction.

The transmission will shift from the current gear to the next lower gear. This action si- multaneously limits the gear range of the transmission (컄 page 134).

Warning!

On slippery road surfaces, never downshift in order to obtain braking action. This could result in drive wheel slip and reduced vehi- cle control. Your vehicle’s ABS will not pre- vent this type of loss of control.

133

Controls in detail Automatic transmission*

Gear ranges

With the selector lever in position D, you can limit the transmission’s gear range by pressing the lever to the left (D-), and re- verse the gear range limit by pressing the lever to the right (D+). The selected gear range will appear in the tachometer display field. If you press on the accelerator when the engine has reached its rpm limit, the transmission will upshift beyond any gear range limit selected.

Effect

Gear range é The transmission shifts through fourth gear only. è The transmission shifts through third gear only. With this selection you can use the braking effect of the engine.

Effect

Gear range ç The transmission shifts

through second gear only. Allows the use of engine’s braking power when driving 앫 on steep downgrades 앫 in mountainous regions 앫 under extreme operating

conditions

æ The transmission operates

only in first gear For maximum use of engine’s braking effect on very steep or lengthy downgrades.

Gear selector lever position

Effect Park position Selector position when the vehicle is parked. Only place selector lever in position P when vehicle is stopped. The park position is not intended to serve as a brake when the vehicle is parked. Rather, the driver should al- ways set the parking brake in addi- tion to placing the selector lever in position P to secure the vehicle. The key can only be removed from the starter switch with the selector lever in position P. With the key re- moved the selector lever is locked in position P.

R Reverse gear

Place selector lever in position R only when vehicle is stopped.

Effect

N Neutral

No power is transmitted from the en- gine to the drive axle. When the brakes are released, the vehicle can be moved freely (pushed or towed). To avoid damage to the transmission, never engage N while driving. If ESP is deactivated or malfunction- ing: Only move selector lever to N if the vehicle is in danger of skidding (e.g. on icy roads).

D Drive

The transmission shifts automatical- ly. All five forward gears are avail- able.

Controls in detail Automatic transmission*

Coasting the vehicle, or driving for any other reason with selector lever in N can result in transmission damage that is not covered by the Mercedes-Benz Limited Warranty.

Warning!

Getting out of your vehicle with the selector lever not fully engaged in position P is dan- gerous. Also, position P alone is not intend- ed to or capable of preventing your vehicle from moving, possibly hitting people or ob- jects.

Always set the parking brake in addition to shifting to position P (컄 page 51). When parked on an incline, turn the front wheels towards the road curb.

135

Controls in detail Automatic transmission*

Warning!

When leaving the vehicle, always remove the key from the starter switch and lock the ve- hicle. Do not leave children unattended in the vehicle, or with access to an unlocked vehicle. Children could move the selector le- ver from position P, which could result in an accident and/or serious personal injury.

136

Program mode selector switch

왘 Press the program mode selector

switch repeatedly until the letter of the desired shift program appears in the multifunction display (컄 page 105). Select W for winter driving: 앫 The vehicle starts out in second

gear (both forward and reverse) for gentler starts. This does not apply if full throttle is applied or gear range 1 is selected.

앫 Traction and driving stability are im-

proved on icy roads.

앫 Upshifts occur earlier even when

you give more gas. The engine then operates at lower rpms and the wheels are less likely to spin.

앫 The power transmission ratio for se- lector lever position R changes de- pending on the program mode selected (W or S).

1 Program mode selector switch S Standard W Winter

For regular driving For winter driving

Never change the program mode when the selector lever is out of position P. It could result in a change of driving char- acteristics for which you may not be prepared.

Accelerator position

Your driving style influences the transmis- sion’s shifting behavior: Less throttle More throttle

Earlier upshifting Later upshifting

Kickdown Use kickdown when you want maximum acceleration. 왘 Press the accelerator past the point of

resistance. The transmission shifts into a lower gear.

왘 Ease on the accelerator when you have

reached the desired speed. The transmission shifts up again.

Emergency operation (Limp Home Mode)

If vehicle acceleration worsens or the transmission no longer shifts, the trans- mission is most likely operating in limp home (emergency operation) mode. In this mode only 2nd gear and reverse gear can be activated. 왘 Stop the vehicle. 왘 Move selector lever to P. 왘 Turn off the engine. 왘 Wait at least ten seconds before re-

starting.

왘 Restart the engine. 왘 Move selector lever to position D (for

2nd gear) or R.
