158Driving and operatingWhen a preceding vehicle is detected
ahead, the distance is indicated in
seconds, displayed on a page in the
Driver Information Centre 3 97 . Press
MENU on the turn signal lever to
select Vehicle Information
Menu ? and turn the adjuster
wheel to choose following distance
indication page.
The minimum indicated distance is
0.5 s.
If there is no vehicle ahead or the vehicle ahead is out of range, two
dashes will be displayed: -.- s.
Parking assist
The parking assist makes parking
easier by measuring the distance between the vehicle and obstacles,
and giving acoustic signals. It is the
driver, however, who bears full
responsibility for the parking
manoeuvre.
The system consists of four ultrasonic parking sensors in the rear bumper. If
the vehicle is equipped with a front
parking assist the system consists of
four additional ultrasonic parking
sensors in the front bumper.
Activation
After ignition is switched on, the rear
parking assist is activated.
The front parking assist can also be activated at a low speed by pressing
r .
An illuminated LED in the parking
assist button indicates that the
system is ready to operate.
An obstacle is indicated by a buzzing
sound. The interval between the sounds becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm, the buzzing is continuous.
196Vehicle caretread life. After changing to winter
tyres, be alert for changes in vehicle
handling and braking.
If using winter tyres, make sure to use ● tyres of the same brand and tread
type on all four wheel positions
● only radial ply tyres of the same size, load range and speed ratingas the tyres originally fitted at the factory.
Winter tyres with the same speed
rating as the tyres originally fitted at
the factory may not be available for H,
V, W, Y and ZR speed rated tyres. If
using winter tyres with a lower speed
rating, never exceed the tyre's
maximum speed capability.

Choose a tyre appropriate for the
maximum speed of your vehicle.
The maximum speed is achievable at kerb weight with driver (75 kg) plus125 kg payload. Optional equipment
could reduce the maximum speed of
the vehicle.

Directional tyres
Fit directional tyres such that they roll in the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring system.
Tyre pressure 3 232.
The tyre pressure information label
on the left or right door frame
indicates the original equipment tyres
and the correspondent tyre
pressures.
The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
Vehicle care197Always inflate the spare tyre to the
pressure specified for full load.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the engine identifier code.
Engine data 3 226.
2. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 232.
For the tyres approved for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
Temperature dependency
The tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase. Tyre pressure
values provided on the tyre
information label and tyre pressure
chart are valid for cold tyres, which means at 20 °C.
The pressure increases by nearly
1.5 psi for a 10 °C temperature
increase. This must be considered
when warm tyres are checked.
The tyre pressure value displayed in
the Driver Information Centre shows
the real tyre pressure. A cooled down
tyre will show a decreased value,
which does not indicate an air leak.
Tyre pressure monitoringsystem
The tyre pressure monitoring system
checks the pressure of all four tyres
once a minute when vehicle speed
exceeds a certain limit.Caution
Tyre pressure monitoring system
warns only about low tyre pressure condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
200Vehicle careTyre pressure sensor matching
process
Each tyre pressure sensor has a
unique identification code. The
identification code must be matched
to a new wheel position after rotating the wheels or exchanging the
complete wheel set and if one or more
tyre pressure sensors were replaced. The tyre pressure sensor matching
process should also be performed
after replacing a spare wheel with a
road wheel containing a tyre pressure sensor.
The malfunction light w and the
warning message should extinguish at the next ignition cycle. The sensors
are matched to the wheel positions,
using a relearn tool, in the following
order: left side front wheel, right side
front wheel, right side rear wheel and
left side rear wheel. The turn signal
light at the current active position is
illuminated until sensor is matched.
Consult a workshop for service. There
are two minutes to match the first
wheel position, and five minutes
overall to match all four wheelpositions. If it takes longer, the
matching process stops and must be
restarted.
The tyre pressure sensor matching
process is:
1. Apply the parking brake.
2. Turn the ignition on.
3. On vehicles with automatic transmission: set the selector
lever to P.
On vehicles with manual
transmission: select neutral.
4. Press MENU on the turn signal
lever to select the Vehicle
Information Menu in the Driver
Information Centre.
5. Turn the adjuster wheel to scroll to
the tyre pressure menu.

212Vehicle careCaution
Never tow a vehicle equipped withAll Wheel Drive (AWD) with the
front or rear tyres on the road. If
you tow a vehicle equipped with
AWD while the front or rear tyres
are rolling on the road, the drive
system in the vehicle could be
severely damaged. When towing
vehicles equipped with AWD, all
four tyres must not be in contact
with the road.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the engine is not running,
considerably more force is needed to
brake and steer.
To prevent the entry of exhaust gases from the towing vehicle, switch on the
air recirculation system 3 127 and
close the windows.
Vehicles with manual transmission:
The vehicle must be towed facing
forwards. The maximum speed is
50 mph. In all other cases, and when
the transmission is defective, the front axle must be raised off the ground.
Vehicles with automatic transmission:
Do not tow the vehicle using a towing eye. Towing with a tow rope could
cause severe automatic transmission damage. When towing vehicles with
automatic transmission, use flat bed
or wheel lift equipment.
Seek the assistance of a workshop. After towing, unscrew the towing eye.
Insert cap and close cap.Towing another vehicle
Disengage the cap by using a
screwdriver and remove.
The towing eye is stowed with the
vehicle tools 3 195.
