154 Starting and drivingSteering wheel lockThe steering wheel lock is electronic. The
lock engages when the remote control is
removed from the ignition and unlocks when
the remote control is inserted. A click can be
heard when the steering wheel lock locks
and unlocks.
If the car is parked with one front wheel
touching the curb, for example, you may
need to turn the steering wheel slightly
when you insert the remote control to allow
the steering wheel lock to unlock. If you do
not succeed on first attempt you must
remove the remote control before trying
again. Turn the steering wheel and insert
the remote control into the ignition switch.
If the steering wheel lock does not disen-
gage it will not be possible to turn the remote
control in the ignition switch.
The following message is shown on the SID:If a fault arises affecting the steering wheel
lock, the following message will be
displayed on the SID:
If the steering wheel lock malfunctions while
the remote control is in the ignition switch,
this may prevent the removal of the remote
control or prevent the car from being
restarted once the engine has been
switched off.
If you have to leave the car, lock the car by
pressing down the lock buttons on the
doors. Lock the front left door from outside
with the traditional key (see page 50). The
car is now locked but the alarm is inactive.
Starting the engine
Pull out key, turn
steering wheel. Restart.
Steering lock malfunc.
Make a safe stop.
WARNING
When starting the engine:
–Sit down in the driver’s seat.
–Depress the clutch pedal fully (M/T). If
the gear lever is not in the neutral posi-
tion, the clutch pedal must be fully
depressed or the car will jump for-
wards or backwards, which may
cause a crash.
–Never start the car from outside the
vehicle, e.g. through a window that is
down. This could lead to serious per-
sonal injury.
Cars with automatic transmission:
select position P to remove the ignition
key. The key can only be removed in
this gear position.
Carbon monoxide (CO) is a colorless,
odorless, poisonous gas. Be alert to
the danger of CO – always open the
garage doors before starting the
engine in the garage.
Do not rest or sleep in the car when
parked with the engine running. There
is a risk of depressing the accelerator
which could lead to engine damage.
There is also a danger of CO poison-
ing if the exhaust system is leaking.

170 Starting and driving
Certain variants also have steering wheel controls for manual gear
selection. On these models, it is possible to change gear manually
using the selector lever and the steering wheel controls. The steer-
ing wheel controls are only active when the selector lever is in the M
position.
Select a higher gear by pressing the right-hand button and a lower
gear by pressing the left-hand button. Sentronic, manual gear selection
Move the selector lever to the manual position (M)
(to the left position D) to select gear manually.
Select a higher gear by pressing the selector lever
forward or a lower gear by pulling it back. The
selector lever will return to a position adjacent to
the letter M after each gear change.
An example of when you may wish to make
manual gear changes is when overtaking, to
enable you to remain in a low gear for an extended
period of time.
If the road surface is slippery, you may wish to start
off in 2nd or 3rd to reduce the risk of wheel spin.
When descending steep hills you should select a
low gear to increase the braking effect of the
engine and thus spare the brakes.
Manual gear selections are displayed on the main instrument
panel. The letter M and the current gear are displayed.
When the selector lever is in the M position, as opposed to the D
position, the engine is much more responsive to changes in accel-
erator position. The accelerator has a different feel.
When changing down, the desired gear can be selected but the
transmission will not change down until the engine speed is low
enough to avoid overrevving.Steering wheel controls for manual gear

171 Starting and driving
Cruise control(Cruise control system)
For safety reasons (brake system func-
tion), the brakes must be applied once
when the engine has started, before the
cruise control system can be activated.
The following message is shown on the SID:
The system has the following functions:
1 ON: engaged
2 OFF: disengaged
3 SET/+: sets the speed and increases
the set speed
4 SET/ –: sets the speed and decreases
the set speed
5 RESUME: re-engages the system at the
set speed
The CRUISE indicator light in the main
instrument panel comes on when the switch
is slid to ON. If you switch off the engine
while the cruise control is ON, the system
will be ON the next time the engine is
started.
To set the desired speed1 Slide the switch to ON.
2 Move the thumbwheel up to SET/+ or
SET/– when the car has reached the
desired speed (above 15 mph
(25 km/h)).To increase the preset speedYou can increase the speed in any of
the following ways:
Accelerate to the desired speed. Jog the
control to SET/+ or SET/–.
Jog the control to SET/+ to increase the
speed by 1 mph (1.6 km/h) (when cruise
control already engaged).
Hold the control in the SET/+ position until
the desired speed is reached (when
cruise control already engaged).
WARNING
Do not use the cruise control system in
wet or icy conditions, in dense traffic or on
winding roads.
Tap brakes lightly
before using cruise ctrl.

173 Starting and driving
ABS brakesThe Antilock Braking System (ABS) modu-
lates the brake pressure to each wheel. The
pressure is automatically reduced just
before the wheel locks up and then
increases again to the point at which the
wheel is just about to lock. The wheel sen-
sors send information to the brake system’s
electronic control module for every 4 or so
inches (decimetre) that the car rolls. This
information is processed continuously to
ensure that the adjustment of the brake
pressure will be as exact as possible.
Adjustment takes place up to 12 times per
second.The brake system provides Electronic
Brakeforce Distribution (EBD). This distri-
butes the brake pressure between the front
and rear wheels, in such a way as to achieve
optimum braking performance irrespective
of the car’s speed or load.
The ABS has a built-in diagnostics function
which will switch on the ABS warning light
if a fault is detected in the system (see
page 82).
The following message will appear on the
SID (and corresponding symbol on main
instrument unit) if a fault is detected:
WARNING
It is prudent to try your brakes from
time to time, especially when driving in
heavy rain, through water collected on
the road, in snow, on a wet road sur-
face or in salty slush. In such condi-
tions, the brakes may take longer than
normal to take effect. To rectify this,
touch the brake pedal periodically to
dry the brakes out.
The same applies after the car has
been washed or when the weather is
very humid.
Avoid parking the car with wet brakes.
Before parking, and if the traffic condi-
tions allow, brake quite heavily so that
the brake discs and pads warm up and
dry.
The brakes are power assisted and it
should be kept in mind that the servo
unit only provides the power assis-
tance when the engine is running.
The brake pressure required when the
engine is off, (e.g. when the car is
being towed) is roughly four times the
normal pedal force required. The
pedal also feels hard and unrespon-
sive.
Overheating can cause the brakes to
fade!
WARNING
The additional safety afforded by the
ABS system is not designed to allow
drivers to drive faster but to make
normal driving safer.
To stop as quickly as possible, without
loss of directional stability, whether
the road surface is dry, wet or slippery,
press the brake pedal down hard
without letting up (do not pump the
pedal), declutching simulta-
neously, and steer the car to safety.

174 Starting and drivingThe ABS system will not reduce the braking
distance on loose gravel, snow or ice but,
because the wheels cannot lock up, steer-
ing control is retained.
When the ABS system operates you will feel
the brake pedal pulsate and hear a ticking
noise, both of which are perfectly normal.
Apply the brake pedal with full force (you
cannot press too hard), declutch and if nec-
essary steer to safety.
Do not release the brake pedal before the
car has come to a halt or the danger is
past!
The above is critical.
If the road is slippery, the ABS system will
operate even when only light pressure is
applied to the brake pedal. This means that
the driver can brake gently to test the condi-
tion of the road and adapt their driving
accordingly.
It is well worth practising the use of ABS
brakes on a skid pad or other suitable
facility.

175 Starting and driving
Traction Control
System (TCS)Anti-spin systemHow the system worksThe 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 uses information from the ABS
wheel sensors to detect when the front (driv-
ing) wheels are rotating faster then the rear
wheels.
If the two front wheels are rotating faster
than the rear wheels, the torque from the
engine is reduced to eliminate the differ-
ence.
The process continues until all the wheels
are rotating at the same speed.
The advantages of the TCS 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
surfaces (e.g. one slippery and one dry),
the TCS functions like an electronic differ-
ential lock, making sure that both wheels
rotate at the same speed. The system
also functions when the car is reversing.
When cornering, if the inside front wheel
rotates faster than the other wheels.
TCS OFF
lights up if:
the system has been switched off
manually. It cannot be switched off if the
car is travelling faster than 35 mph
(60 km/h).
there is a fault in the ABS system
a fault has been detected and the system
has therefore been switched off and at the
same time the following message is
shown on the SID:
WARNING
When driving normally, the TCS system
helps to improve the car’s stability,
maneuverability and traction under slip-
pery road and extreme driving conditions.
The TCS must not be regarded as a
system to enable the driver to maintain
higher speeds. The same precautions
must be adopted as normal for safe cor-
nering and driving on slippery roads.

176 Starting and drivingTCS indicatorWhen the ignition switch is turned to the ON
position, the lamp is lit for about 4 seconds
while the system performs self-diagnosis.
The light comes on when the TCS is
operative, that is when one of the wheels
has lost its grip.
The fact that the TCS is operative indicates
that the limit for grip has been exceeded and
that the driver must exercise greater care.
Temporarily turning the TCS offThe TCS is switched on automatically when
the engine is started.
It may be necessary to switch off the system
if the car has become bogged down, for
instance.
If a fault is detected in the ABS, the TCS will
be switched off automatically.
The cruise control system (if active) will
automatically be disengaged if the TCS is
operative.Disengage the system in Settings.

wheel buttons, or .
2 Hold the SET button depressed until a
chime sounds.
3Select TCS.
4 Press the SET button.
5Select ON or OFF.
End by pressing the SET-button.
Go back/undo using the CLR-button.

177 Starting and driving
Electronic Stability
Program ESP
®
Anti-skid system
The ESP
® system employs both the
antilock braking system (ABS) and the trac-
tion control system (TCS). It is a system that
helps the driver to stabilize the car in
unusual circumstances that can otherwise
be more difficult to handle.
How the ESP
® system works
The ESP
® system can help to prevent the
car from skidding by braking one or several
wheels independently of the driver. The
engine output is then also reduced to pre-
vent the driving wheels from spinning. The
car has sensors that measure wheel speed,
yaw rate, lateral acceleration, steering
wheel position and braking pressure. The
values provided by these sensors are used
to calculate the actual direction of the car,
the intentions of the driver and whether the
ESP
® system should be engaged.
If this direction does not agree with that
intended by the driver, calculated from the
steering wheel position, the ESP
® system is
engaged.
The ESP
® system improves the driver’s
chances of retaining control over the car in
a critical situation.
WARNING
When driving normally, the ESP
® system
helps to improve the car’s stability and
maneuverability under slippery road and
extreme driving conditions. The ESP
®
system must not be regarded as a system
to enable the driver to maintain higher
speeds. The same precautions must be
adopted as normal for safe cornering and
driving on slippery roads must be
adopted.

brakes on one or several wheels in order
