close the fuse box cover and press
until it engages.
If the fuse box cover is not closed
correctly, malfunction may occur.

to tyre width), %R:belt type: RadialRF:type: RunFlat16:wheel diameter, inches95:load index e.g. 95 is equivalent to 690 kgV:speed code letter

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 3 294.
Directional tyres
Directional tyres should be mounted
so that they rotate in the correct
direction. The proper rotation
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 3 301.
The tyre pressure information label
on the left 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.
Always 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.
Make sure tyre loading setting
matches the current tyre pressure.
Tyre loading 3 264.
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 drive axle and body style.
2. Identify the engine identifier code.
Engine data 3 293.
3. Identify the respective tyre.

270Vehicle care2.Type 1: screw the compressor air
hose to the connection on the
sealant bottle and fit the sealant
bottle into the retainer on the
compressor.
Type 2: remove screw plug from
the compressor and from the
sealant bottle. Screw the bottle on the compressor without removing
the tinfoil from the bottle.
3. Set the compressor near the tyre in such a way that the sealant
bottle is upright.
4. Unscrew valve cap from defective
tyre.
5. Type 1: screw the filler hose to the
tyre valve.
Type 2: remove protection cap
from filler hose and screw the filler
hose to the tyre valve. The air
release valve must be closed (turn
clockwise).
6. The switch on the compressor must be set to J.
7. Connect the compressor plug to the power outlet or cigarette
lighter socket.
To avoid discharging the battery,
we recommend running the
engine.
8. Set the rocker switch on the compressor to I. The tyre is filled
with sealant.

Vehicle care277Jump starting
Do not start with 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 vehicle battery
to naked flames or sparks.
● A discharged vehicle battery can already 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 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.
Page 280 of 323

278Vehicle care3. Connect the black lead to thenegative terminal of the booster
battery.
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 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.Towing
Towing the vehicle
Disengage cap at slot and remove
downwards.
The towing eye is stowed with the
vehicle tools 3 261.
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.
Switch the selector lever to neutral.
Release the parking brake.
Page 281 of 323

Vehicle care279Caution
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 manual transmission
and All-wheel drive: If the vehicle is
towed with all four wheels on the
ground then there are no technical
limitations for speed and distance. If
only one axle has been raised, the
maximum speed is 50 km/h. There is
no distance limitation.
Vehicles with automatic transmission and All-wheel drive: The vehicle must
be towed facing forwards. If the
vehicle is towed with all four wheels
on the ground, the maximum speed is 50 km/h and for a maximum of
50 km. If the front axle has been
raised, the maximum speed is
50 km/h. There is no distance
limitation.
Seek the assistance of a workshop.
After towing, unscrew the towing eye.
Iinsert cap with the outer flange into
the recess and fix cap by pushing.
Towing another vehicle
Disengage cap at bottom and remove downwards.
The towing eye is stowed with the
vehicle tools 3 261.
Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
The lashing eye at the rear
underneath the vehicle must never be used as a towing eye.
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 a
vehicle.
