Vehicle care221Temperature dependencyThe 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.
Tyre deflation detectionsystem
The tyre deflation detection system continually checks the rotation speed
of all four wheels and warns on low
tyre pressure condition once vehicle
is driving. This is achieved by
comparing tyre rolling circumference
with reference values and further
signals.
If a tyre loses pressure the control
indicator w illuminates and a warning
message is displayed in the Driver
Information Centre.In this case reduce speed, avoid
sharp cornering and strong braking.
Stop at next safe opportunity and
check tyre pressure.
Control indicator w 3 96.
After adjusting tyre pressure initialise
system to extinguish the control
indicator and restart system.Caution
Deflation detection system warns
just about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
In case of a system malfunction a
message is displayed in the Driver
Information Centre. Set correct tyre
pressure and reinitialise system. If the
failure continues to be displayed,
contact a workshop. The system is
inoperable when ABS or ESC has a
malfunction or a temporary spare
wheel is used. Once the road tyre has
been refitted, check the tyre pressure with cold tyres and initialise the
system.
System initialisation
After tyre pressure correction or
wheel change, the system must be
initialised to learn new circumference reference values:
1. Always ensure that all four tyres have correct tyre pressure3 255.
2. Apply parking brake. 3. Press w to reset deflation
detection system.
4. Reset is confirmed by pop-up indication.
Vehicle care223Wheel covers
Wheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination
requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
not have a rim protection ridge.
Wheel covers must not impair brake
cooling.9 Warning
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
Vehicles with steel wheels: When
using locking wheel nuts, do not
attach wheel covers.
Tyre chains
Tyre chains are only permitted on the
front wheels.
Always use fine mesh chains that add no more than 9 mm to the tyre tread
and the inboard sides (including chain
lock).
9 Warning
Damage may lead to tyre blowout.
Tyre chains are permitted on tyres of
size 215/70R16, 215/65 R17,
225/55 R18 and 205/55 R19.
Temporary spare wheel
The use of tyre chains is not permitted
on the temporary spare wheel.
Tyre repair kit
Minor damage to the tyre tread can be repaired with the tyre repair kit.
Do not remove foreign bodies from
the tyres.
Tyre damage exceeding 4 mm or that
is at tyre's sidewall cannot be repaired with the tyre repair kit.9 Warning
Do not drive faster than 50 mph.
Do not use for a lengthy period.
Steering and handling may be
affected.
In the case of a flat tyre:
Apply the parking brake and engage
first gear, reverse gear or P.
226Vehicle care
16. Continue driving immediately sothat sealant is evenly distributed
in the tyre. After driving approx.
3 miles but no more than
10 minutes, stop and check tyre
pressure. Screw compressor air
hose directly onto tyre valve when
doing this. Fill tyre as described
before. Drain excess tyre
pressure with the button on the air
hose.
If tyre pressure hasn't decreased
under 150 kPa (1.5 bar), set it to
the correct value. Otherwise the
vehicle must not be used. Seek
assistance of a workshop 3 255.
Repeat the checking procedure
once more after driving further
3 miles but no more than
10 minutes to check that there is
no more loss of pressure.
If the tyre pressure has fallen
below 150 kPa (1.5 bar), the
vehicle must not be used. Seek
the assistance of a workshop.
17. Stow away tyre repair kit in load compartment.
Notice
The driving characteristics of the repaired tyre are severely affected,
therefore have this tyre replaced.
If unusual noise is heard or the
compressor becomes hot, turn
compressor off for at least 30 min.
The built-in safety valve opens at a
pressure of seven bar (102 psi).
Note the expiry date of the kit. After
this date its sealing capability is no
longer guaranteed. Pay attention to
storage information on sealant
bottle.Replace the used sealant bottle. Dispose of the bottle as prescribed
by applicable laws.
The compressor and sealant can be used from approx. -30 °C.
Wheel changing
Make the following preparations and
observe the following information:
● Park the vehicle on a level, firm and non-skid surface. The front
wheels must be in the straight- ahead position.
● If necessary, place a chock under
the wheel diagonally opposite the
wheel to be changed.
● Apply the parking brake and engage first gear, reverse gear orP .
● If the ground on which the vehicle
is standing is soft, a solid board
(max. 1 cm thick) should be
placed under the jack.
● Take heavy objects out of the vehicle before jacking up.
● No people or animals may be in the vehicle when it is jacked-up.
228Vehicle careFront arm position of the lifting
platform centrically under the relevant vehicle jacking point.
Spare wheel
The spare wheel can be classified as
a temporary spare wheel depending
on the size compared to the other
mounted wheels and country
regulations. In this case a permissible maximum speed applies, even
though no label at the spare wheel
indicates this.
Only mount one temporary spare
wheel. Do not drive faster than
50 mph. Take curves slowly. Do not
use for a long period of time.Caution
The use of a spare wheel that is smaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
The spare wheel is located in the load
compartment beneath the floor
covering.
To remove: 1. Open the floor cover 3 71.
2. Remove the tool box.
3. The temporary spare wheel is secured with a wing nut. Unscrew
nut and take out the spare wheel.
4. When, after a wheel change, no wheel is placed in the spare wheelwell, secure the tool box by
tightening the wing nut as far as it
will go and close floor cover.
5. After wheel change back to full size wheel, place the temporary
spare wheel outside up in the well and secure with the wing nut.
Only mount one temporary spare
wheel. The permissible maximum
speed on the label on the temporary
spare wheel is only valid for the
factory-fitted tyre size.
Fitting the spare wheel
Make the following preparations and
observe the following information:
● Park the vehicle on a level, firm and non-skid surface. The front
wheels must be in the straight- ahead position.
● If necessary, place a chock under
the wheel diagonally opposite the
wheel to be changed.
● Apply the parking brake and engage first gear, reverse gear or
P .
232Vehicle care● A discharged vehicle battery canalready freeze at a temperature
of 0 °C. Defrost the frozen battery before connecting jump leads.
● Wear eye protection and protective clothing when
handling a battery.
● Use a booster battery with the same voltage (12 V). Its capacity
(Ah) must not be much less than
that of the discharged vehicle
battery.
● Use jump leads with insulated terminals and a cross section of
at least 16 mm 2
(25 mm 2
for
diesel engines).
● Do not disconnect the discharged
vehicle battery from the vehicle.
● Switch off all unnecessary electrical consumers.
● Do not lean over the vehicle battery during jump starting.
● Do not allow the terminals of one
lead to touch those of the other
lead.● The vehicles must not come into contact with each other during
the jump starting process.
● Apply the parking brake, transmission in neutral,
automatic transmission in P.
Open the positive terminal protection
caps of both vehicle batteries.
Lead connection order: 1. Connect the red lead to the positive terminal of the booster
battery.
2. Connect the other end of the red lead to the positive terminal of the
discharged battery.
3. Connect the black lead to the negative terminal of the boosterbattery.
4. Connect the other end of the black
lead to a vehicle grounding point
of your vehicle in the engine
compartment.
Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the engine: 1. Start the engine of the vehicle providing the jump.
2. After 5 minutes, start the other engine. Start attempts should be
made for no longer than
15 seconds at an interval of
1 minute.
3. Allow both engines to idle for approx. 3 minutes with the leads
connected.
4. Switch on electrical consumers e.g. headlights, heated rear
window of the vehicle receiving
the jump start.
5. Reverse above sequence exactly when removing leads.
Vehicle care233Towing
Towing the vehicle
Remove the cap.
The towing eye is stowed with the
vehicle tools 3 218.
Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
Attach a tow rope – or better still a tow
rod – to the towing eye.
The towing eye must only be used for towing and not for recovering the
vehicle.
Switch on ignition to release steering
wheel lock and to permit operation of
brake lights, horn and windscreen
wiper.
Caution
Deactivate the driver assistance
systems like active emergency
braking 3 169, otherwise the
vehicle may automatically brake during towing.
Switch the selector lever to neutral.
Release the parking brake.
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 and close the
windows.
Vehicles with automatic transmission: The vehicle must be towed facing
forwards, not faster than 50 mph nor further than 60 miles. In all other
