The jack, wheel bolt wrench and
some tools are located on the right
side of the load compartment, behind a cover 3 69.
Wheels and tyres
Tyre condition, wheel condition
Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
We recommend not swapping the
front wheels with the rear wheels and vice versa, as this can affect vehicle
stability. Always use less worn tyres
on the rear axle.
Winter tyres
Winter tyres improve driving safety at temperatures below 7 °C and should
therefore be fitted on all wheels.
All tyre sizes are permitted as winter
tyres 3 251.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.Tyre designations
E.g. 195/55 R 16 95 H195:tyre width, mm55:cross-section ratio (tyre height

Choose a tyre appropriate for the
maximum speed of your vehicle.
The maximum speed is achievable at kerb weight with driver (75 kg) plus
125 kg payload. Optional equipment
could reduce the maximum speed of
the vehicle.
Performance 3 245.

Vehicle care215The use of commercially-available
liquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.
Operating electronic devices or being
close to facilities using similar wave
frequencies could disrupt the tyre
pressure monitoring system.
Each time the tyres are replaced, tyre pressure monitoring system sensors
must be dismounted and serviced.
For the screwed sensor; replace
valve core and sealing ring. For the
clipped sensor; replace complete
valve stem.
Vehicle loading status Adjust tyre pressure to load condition
according to the tyre information label or tyre pressure chart 3 251, and
select the appropriate setting in the
menu Tyre Load in the Driver
Information Centre, Vehicle
Information Menu 3 96 . This setting is
the reference for the tyre pressure
warnings.The menu Tyre Load only appears
when the vehicle is at a standstill and the parking brake is applied. On
vehicles with automatic transmission, the selector lever must be in P.
Midlevel display:
Select ● LO for comfort pressure up to
three people.
● ECO for Eco pressure up to
three people.
● Hi for full loading.
Uplevel display:
Select ● Light for comfort pressure up to
three people.
● Eco for Eco pressure up to
three people.
● Max for full loading.
Tyre pressure sensor matching process
Each TPMS 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

216Vehicle carepressure sensors were replaced. Thetyre 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 or code 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 wheel
positions. 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 automated: Keep
brake pedal depressed. Move and hold the selector lever for five
seconds to position N until P is
displayed in the Driver
Information Centre. P indicates
that the tyre pressure sensor
matching process can be started.
On vehicles with manual
transmission: select neutral.
4. Use 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.

Vehicle care219Do not remove foreign bodies from
the tyres.
Tyre damage exceeding 4 mm or that
is at the tyre's side wall near the rim
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.
If you have a flat tyre:
Apply the parking brake and engage
first gear, reverse gear or P.
The tyre repair kit is stowed in the load
compartment.
Depending on the equipment, the tyre repair kit is in a compartment in the
right sidewall or in a compartment
under the floor cover.
Vehicles with tyre repair kit under
the floor cover
1. Take the tyre repair kit from the compartment.
2. Remove the compressor.
3. Remove the electrical connection cable and air hose from the
stowage compartments on the
underside of the compressor.

224Vehicle careWheel changingMake 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.
● Apply the parking brake and engage first gear, reverse gear orP .
● Never change more than one wheel at once.
● Use the jack only to change wheels in case of puncture, not
for seasonal winter or summer
tyre change.
● The jack is maintenance-free. ● 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.
● Never crawl under a jacked-up vehicle.●Do not start the vehicle when it is

228Vehicle careThe following applies to tyres fitted
opposing the rolling direction:
● Driveability may be affected. Have the defective tyre renewed
or repaired as soon as possible
and fit it instead of the spare
wheel.
● Drive particularly carefully on wet
and snow-covered road
surfaces.Jump starting
Do not start with a quick charger.
A vehicle with a discharged vehicle
battery can be started using jump
leads and the vehicle battery of
another vehicle.9 Warning
Be extremely careful when starting
with jump leads. Any deviation
from the following instructions can
lead to injuries or damage caused
by battery explosion or damage to the electrical systems of both
vehicles.
9 Warning
Avoid contact of the battery with
eyes, skin, fabrics and painted
surfaces. The fluid contains
sulphuric acid which can cause
injuries and damage in the event
of direct contact.
● Never expose the battery to naked flames or sparks.
● 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 Volts). 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 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.

Vehicle care229● 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
vehicle battery.
2. Connect the other end of the red lead to the positive terminal of the
discharged vehicle battery.
3. Connect the black lead to the negative terminal of the booster
vehicle battery.
4. Connect the other end of the black
lead to a vehicle grounding point,
such as the engine block or an
engine mounting bolt. Connect as far away from the discharged
vehicle battery as possible,
however at least 60 cm.
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 five minutes, start the other engine. Start attempts should be
made for no longer than
15 seconds at an interval of one
minute.
3. Allow both engines to idle for approx. three 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.
