138 Starting and drivingAutomatic transmission
The electronic control module for the auto-
matic transmission receives information on
engine torque and road speed, and also
controls the hydraulic pressure in the trans-
mission to ensure that gear changing is as
smooth as possible.
The position of the selector lever is shown
by the symbols adjacent to the lever and
also by an indicator on the main instrument
panel.
The ignition key can only be removed when
the selector lever is in the P position. When the car is stationary, the engine must
be at idling speed when the selector lever is
moved. You must have your foot on the
brake pedal to move the lever out of park.
If the accelerator is depressed while the
lever is moved, this will result in abnormal
wear in the transmission.
WARNING
 Make it a habit to keep your foot on the
brake when selecting a drive position,
to prevent the car creeping forward (or
backward if reverse is selected).
 The car must be at a standstill before
P, R or N is selected. You have to have
your foot on the brake pedal to move
the lever out of P. If the car is still
moving when a drive position is subse-
quently selected, this could cause an
accident or damage the automatic
transmission.
 Never park the car with the selector
lever in a drive position, even if the
parking brake is on.
 Always select "P" position and apply
the parking brake when leaving the
vehicle unattended.
NOTEAfter selecting a drive position, pause to
allow the gear to engage before you
accelerate.

139 Starting and driving
The detent button on the selector lever has
to be pressed before the selector can be
moved between certain positions. Three modes for the automatic transmis-
sion can be selected: Normal, Sport and
Winter.
The Normal mode, which provides the best
fuel economy, is the default setting when
the engine is started.
When the Sport mode is selected, the
throttle angle is altered to provide more
power at the same throttle setting. The
transmission also changes up later than in
Normal mode to provide higher perfor-
mance. In this mode, the SPORT indicator
will appear on the main instrument panel
(see page 144).
The Winter mode is intended for use when
pulling away and driving on icy roads. In this
mode, the transmission starts in 3rd gear, to
provide better grip, and the WINTER indica-
tor appears on the main instrument panel.
When the ignition is turned to OFF, the auto-
matic transmission will automatically revert
to Normal mode (see page 144).
Adaptive gear-change pattern is a trans-
mission function in the Normal and Sport
modes which matches gear changing to
current driving conditions. The transmission
control module senses the load on the
engine and selects one of three available
gear-change patterns, and so avoids
unnecessary changing up or down.
Lock-up function The automatic transmission has a lock-up
function, which renders the torque con-
verter inoperative in 3rd and 4th gears, the
result of which is to reduce the engine speed
and, hence, fuel consumption.
When the lock-up function comes into oper-
ation, it may give the impression of an over-
drive being engaged.Kick-downWhen the accelerator is pressed down hard,
a change-down to the next gear will be
effected to provide maximum acceleration,
e.g. for overtaking.
The change-up to the next gear again will
take place either when the accelerator is
released or when maximum engine speed is
reached.

147 Starting and driving
The ABS system will not reduce the braking
distance on loose gravel or on snow or ice
but, because the wheels cannot lock up,
some steering control is retained.
When the ABS system is working, i.e. mod-
ulation of the brake pressure is in progress,
the brake pedal will pulsate and a ticking
noise will be heard. All this is perfectly nor-
mal.
Press the pedal down hard (you cannot
press too hard) and steer the car to safety. Do not release the brake pedal before the
car has come to a halt or the danger is
past!
That is critical.
If the road is slippery, the ABS system will
operate even when only light pressure is
applied to the pedal. This means that you
can brake gently to test the condition of the
road and adapt your driving accordingly.
It is well worth practicing the use of ABS
brakes on a skid pan or other suitable facil-
ity.
Traction Control SystemHow the system works The traction control system (TCS) is
designed to prevent wheelspin. This
enables the car to achieve the best possible
grip and, hence, maximum tractive effort,
together with greater stability.
The TCS system uses information from the
ABS system’s wheel sensors to detect
when the front (driving) wheels are rotating
faster then the rear wheels. It then monitors
whether one driving wheel is rotating faster
than the other. If so, the faster wheel is
retarded until both wheels are rotating at the
same speed.
If the two front wheels are rotating at the
same speed but are turning faster than the
rear wheels, the torque from the engine is
reduced to eliminate the difference.
The process continues until all the wheels
are rotating at the same speed.
The advantages of the TCS system become
most apparent when the cohesion between
the front wheels and the road surface is so
low that one or both of the wheels would
lose their grip were the car not equipped
with the TCS, e.g.:
 When the car is pulling away or accelerat-
ing with the front wheels on different sur-
faces (e.g. one slippery and one dry). The
TCS then functions like an electronic dif-
ferential lock.
 When the car is pulling away or accelerat-
ing on a slippery road, in which case the

170 Car care and technical informationORVR (Onboard Refueling Vapor
Recovery)Hydrocarbon vapors formed when refueling
will be recovered by the car and not
released into the atmosphere. The hydro-
carbons are absorbed in a evaporative
emission canister. When the engine is sub-
sequently started, the evaporative emission
canister is gradually purged as air is sucked
into it through a shut-off valve. The hydro-
carbon/air mixture passes through the evap
canister purge valve and into the engine
where it is burned.
When refueling, make sure you screw the
filler cap on and keep turning until it has
clicked at least 3 times. Otherwise, it is pos-
sible for the CHECK ENGINE light to illumi-
nate and a “TIGHTEN FUEL FILLER CAP“
message to appear on SID.
Refueling, see page 134.
Engine2.3-liter engineThe 2.3-liter model is a transverse, 4-cylin-
der in-line engine with twin overhead cam-
shafts and 4 valves per cylinder.
This engine is equipped with balance shafts
that reduce engine vibration to a minimum.
The balance shafts are chain driven and
rotate at twice the speed of the crankshaft.
They produce forces and torques that are
opposed to those generated by the pistons
and connecting rods, an effect that occurs
twice for each revolution of the engine.
Engine noise is also reduced as the
counter-rotating shafts counteract the vibra-
tion from the moving parts of the engine.
The transmission, located on the right
(viewed from the front), is integrated with
the engine. All models have front-wheel
drive.
3.0-liter V6 engine The 3.0-liter engine is a transverse, V6
engine with each bank of cylinders having
double overhead camshafts and 4 valves
per cylinder.
The transmission, located on the right
(viewed from the front), is integrated with
the engine. All models have front-wheel
drive.

178 Car care and technical informationCharging/replacing the batteryConnect the positive lead to the positive (+)
battery terminal (red), and the negative lead
to a good ground point, e.g. the lifting lug at
the front of the engine.
To remove the battery, always disconnect
the negative (black) lead first and reconnect
it last when fitting the new battery.
The battery size must comply with DIN
53735 MFI 230/2.16. NOTETo avert the danger of short-circuiting
between the positive (+) terminal on the
battery and the inlet manifold on the
engine, always disconnect the negative
(-) battery lead first and reconnect it last.NOTE Never reverse the polarity of the bat-
tery by connecting the leads to the
wrong terminals. The red, positive
lead connects to the positive (+) termi-
nal, and the black, negative lead to the
negative (-) terminal.
 Serious damage can be done to the
car’s electrical system if a battery or
alternator lead is disconnected while
the engine is running.
 The nut on the battery clamp should
be tightened to a torque of 10 Nm.

4 Wind the jack to raise the wheel clear of
the ground. Remove the wheel bolts and
lift off the wheel.
5 Fit the wheel and screw in the bolts in the
sequence shown (opposite pairs).
Tighten the bolts enough for the bolts
and wheel to be seated correctly.
6 Lower the car and tighten the wheel
bolts to the correct torque in the
sequence shown (opposite pairs).
Tightening torque
Light-alloy wheels: 80 ft.lbs. (110 Nm)
Steel wheels: 80 ft.lbs. (110 Nm)
Do not overtighten the bolts using a per-
cussion nut tightener: not only can this
damage the wheels but it can also make it impossible to undo the bolts using the
wheel wrench in the car’s toolkit.
7 Check-tighten the wheel bolts after a
few miles.
Tightening torque
Light-alloy wheels: 80 ft.lbs. (110 Nm)
Steel wheels: 80 ft.lbs. (110 Nm)
We advise against using wheels with open
wheel covers in winter, as the brake compo-
nents are then more exposed both to slush
and to road salt and grit.
NOTEWhen refitting wheel covers (where
applicable), make sure that the valve
protrudes through the hole in the wheel
cover.
