164 Starting and driving
Park Brake Shift Lock
The transmission has a security function
known as Park Brake Shift Lock. To move
the gear selector lever out of the P or N posi-
tion, the gear selector lever detent (catch)
must be pressed in at the same time as the
brake pedal is held depressed.
The detent button on the selector lever has
to be pressed in before the lever can be
moved between certain positions.
Temporary override of Park Brake Shift
Lock, see page 166.
Adaptive gear change patterns
The adaptive gear change pattern function
adapts gear changing to the prevailing driv-
ing conditions. The transmission control
module senses the engine load, vehicle
speed and temperature of the transmission.
A suitable gear change pattern is then
selected automatically to avoid unneces-
sary gear changes and undesired increases
in transmission temperature.
Certain variants use a special change pat-
tern for the first few minutes after a cold start
so that the catalytic converter reaches its
working temperature more quickly.
Thermal transmission protection
The transmission has built-in protection
against overheating. If the temperature of
the transmission fluid exceeds 302°F
(150°C), engine torque will be limited to
147 ft.lbs. (200 Nm).
The following message is shown on the SID:
If this message appears, stop the car as
soon as it is safe to do so and allow the
engine to idle until the message has gone
out. The selector lever should be in
position P.
Lock-up
The transmission’s torque converter has a
lock-up function. This can lock the torque
converter, thus reducing the engine speed
and fuel consumption.
Kick-down
When the accelerator is pressed down fully,
a down change is made to optimize acceler-
ation, e.g. for overtaking.
Following this, the next higher gear will be
selected at the optimum engine speed,
unless you ease off the accelerator before
reaching this.
Gearbox too hot. Make a
safe stop. Open hood.
