Mercedes-Benz 1998 SL 500 Operator's Manual page 83

Important!
With selector lever in position "D", "4"
or "3", upshifting from 1st to 2nd to 3rd
gear is delayed depending on vehicle
speed and engine temperature. This
allows the catalytic converter to heat up
more quickly to operating
temperatures.
During the brief warm-up period this
delayed upshift and increased engine
noise might be perceived as a
malfunction. However, neither the
engine nor transmission are negatively
affected by this mode of operation.
The delayed upshift is effective
with vehicle speeds below
31 mph (50 km/h) at partial throttle
and engine temperatures below
95°F(35°C).
To avoid overrevving the engine when
the selector lever is moved to a lower
driving range, the transmission will not
shift to a lower gear as long as the
vehicle speed exceeds the speed limit
of that gear.
To prevent the engine from laboring at
low RPMs, do not allow the engine
speed to drop too low on uphill
gradients.
Depending on the degree of the
incline, shift selector lever to a lower
gear range early enough to maintain
engine RPM within the best torque
range.
Warning!
On slippery road surfaces, never
downshift in order to obtain
braking action. This could result in
rear wheel slip and reduced vehicle
control. Your vehicle's ABS will not
prevent this type of loss of control.
Maneuvering
To maneuver in tight areas, e.g. when
pulling into parking space, control the
car speed by gradually releasing the
brakes. Accelerate gently and never
abruptly step on the accelerator.
To rock a car out of soft ground (mud
or snow), alternately shift from
forward to reverse, while applying
slight partial throttle.
Rocking a car free in this manner may
cause the ABS warning lamp to come
on. Turn off and restart the engine to
clear the malfunction indication.
Stopping
For brief stops, e.g. at traffic lights,
leave the transmission in gear and hold
vehicle with the service brake.
For longer stops with the engine idling,
shift into "N" or "P".
When stopping the car on an uphill
incline, do not hold it with the
accelerator, use the brake. This avoids
unnecessary transmission heat build up.
Warning!
Getting out of your car with the
selector lever not fully engaged in
position "P" is dangerous. When
parked on a steep incline, position
"P" alone may not prevent your
vehicle from moving, possibly hitting
people or objects.
Always set the parking brake in
addition to shifting to position "P".
When parked on an incline,
also turn front wheel against curb.
