Starting and driving

Automatic gearbox (option)

Cold start
When starting in low temperatures, shifting
may feel harder. This is due to the viscosity of
the gearbox oil at low temperatures. To
minimise engine emissions, the gearbox
shifts up later than normal if the engine has
been started at low temperature.
NOTE! Depending on the engine
temperature when starting, the engine speed
after a cold start may be higher than normal
for certain engine types.
Turbo engine
When the engine is cold, the transmission
shifts gears at higher engine speeds than
normal. This is to help the catalytic converter
reach normal operating temperature faster
with less exhaust emission.
Adaptive system
The gearbox is controlled by what is known
as an adaptive system. The control module
continually " learns " how the gearbox
behaves. It senses how the gearbox shifts
gears and achieves optimal gear shifts each
time. The control module also senses driving
behaviour, such as how hard the driver
depresses the accelerator, and adjusts the
sensitivity of the shift schedule to a driving
style. The gears have a Lock-up function
100
(locked gears) which provides better engine
braking and lowerfuel consumption.

Safety systems

Cars with automatic gearboxes have special
safety systems:
Keylock
The gear selector must be in position P
before the key can be removed from the
ignition. The key is blocked in all other
positions.
Parking position (P)
Stationary car with the engine running:
• Hold your foot on the brake pedal when
moving the gear selector to another
position.
Shiftlock
The ignition key must be in position II and the
brake pedal pressed before the gearshift can
be moved from position P.
Disengaging the shift lock
In certain cases it may be necessary to move
the car when it is not driveable, for example if
the battery is discharged. Carry out the
following to move the car:
1. There is a small cover behind P-R-N-D
on the gear selector panel. Open the
rear edge of the panel.
2. Insert a screwdriver or similar to the
bottom whilst pressing the lever out of
the P position.
Neutral (N)
If the car has been stationary for more than 5
seconds, the ignition key must be in position
II and the brake pedal pressed before the
gear selector can be moved from N.
