Selector Lever Positions - Porsche Boxster Owner's Manual

Selector Lever Positions

P - Parking lock
Engage parking lock only when vehicle is
stationary.
Engage parking lock after applying the
handbrake and release it before releasing
the handbrake.
The ignition key can be withdrawn only in selector
lever position P.
R - Reverse
Select only if car is stationary and the brake is
applied.
N - Neutral
Selector lever position N must be selected for
towing or in car washes, for example.
Select the desired position for moving off (D,
M or R) only when the engine is idling and while
depressing the brake pedal.
D - Automatic selection mode
Mode of operation
Select position D for "normal" driving. The
gears are shifted automatically according to
the accelerator position and speed.
Depending on the way the vehicle is driven and
on the resistance (e.g. uphill), the gear-changing
points are shifted towards higher or lower engine-
speed ranges. The accelerator position, driving
speed, engine speed, longitudinal and lateral
acceleration and the road profile all have an
influence on the gear-changing characteristic.
Unwanted upward shifts, e.g. before bends, are
prevented by swiftly releasing the accelerator
pedal.
Depending on lateral acceleration, upward shifts
on bends are not made until the engine-speed limit
is reached.
Under braking, and depending on the amount of
deceleration, the Tiptronic shifts down earlier. For
subsequent cornering, the right gear is engaged
when pressure is applied to the brakes before the
bend. The bend is taken in the right gear, and when
you accelerate out of the bend you do not have to
shift down.
Sport mode switched on
Please observe the chapter "SPORT MODE" on
page 70.
If the Sport mode programme is switched on,
Tiptronic switches to a sporty gear-changing map
and shortens the shifting periods.
Initial Drive-off
In 2nd gear, the vehicle drives off with the throttle
only slightly open. Drive off in 1st gear with the
throttle open wider or when the engine is cold.
Shifting gear on the steering wheel
With the toggle switches on the steering wheel, you
can change temporarily from automatic selection
mode D to manual mode M.
Advantages:
– Shifting down before bends and on entering
built-up areas.
– Shifting down on downward slopes (engine
braking).
– Shifting down for brief spurts of acceleration.
– Selecting 1st gear for moving off.
The manual selection mode remains engaged:
– for cornering (depending on the lateral
acceleration) and overrunning,
– when the vehicle is stationary (e.g. at a
junction).
The system leaves manual selection mode:
– automatically after approx. 8 seconds (unless
cornering or overrunning),
