WARNING Risk of accident due to incor-

rect footwear

&

WARNING Risk of accident due to objects

in the driver's footwell

Incorrect footwear includes, for example:

This also applies when the engine or parts of the

drivetrain have been replaced.

R

Shoes with platform soles

Objects in the driver's footwell may impede

pedal travel or block a depressed pedal.

R

Shoes with high heels

Please also observe the following breaking-in

notes:

R

Slippers

This jeopardizes the operating and road safety

of the vehicle.

R

In certain driving and driving safety systems,

There is a risk of an accident.

#

Stow all objects in the vehicle securely

so that they cannot get into the driver's

footwell.

the sensors adjust automatically while a cer-

tain distance is being driven aꢀer the vehicle

has been delivered or aꢀer repairs. Full sys-

tem eꢂectiveness is not reached until the end

of this teach-in process.

Always wear suitable footwear so that

you can operate the pedals safely.

#

Always install the ꢄoor mats securely

&

WARNINGG Risk of accident if the vehicle is

switched oꢂ while driving

and as prescribed in order to ensure that

there is always suꢁcient room for the

pedals.

R

Brakepads, brake discs and tires that are

either new or have been replaced only achieve

optimum braking eꢂect and grip aꢀer several

hundred kilometers of driving. Compensate for

the reduced braking eꢂect by applying greater

force to the brake pedal.

If you switch oꢂ the vehicle while driving,

safety functions are restricted or no longer

available.

#

Do not use loose ꢄoor mats and do not

place ꢄoor mats on top of one another.

This may aꢂect the power steering system and

the brake force boosting, for example.

You will need to use considerably more force

to steer and brake, for example.

#

Do not switch oꢂ the vehicle while driv-

ing.

Driving and parking

&

The possibility of a serious or even fatal acci-

dent are greatly increased when you drink or

take drugs and drive.

DANGER Risk of fatal injuries caused by

exhaust gases

DANGER Risk of fatal injury due to poison-

ous exhaust gases

Combustion engines emit poisonous exhaust

gases, such as carbon monoxide. Inhaling

these exhaust gases is hazardous to health

and leads to poisoning.

If the tailpipe is blocked or suꢁcient ventila-

tion is not possible, poisonous exhaust gases

such as carbon monoxide may enter the vehi-

cle. This is the case, for example, if the vehicle

gets stuck in the snow.

#

Do not drink or take drugs and drive or

allow anyone to drive who has been

drinking or taking drugs.

#

Never run the vehicle and, if present, the

stationary heater indoors without suꢁ-

cient ventilation.

&

WARNING Risk of accident due to the

brake system overheating

#

Keep the tailpipe and the area around

the vehicle free from snow when the

vehicle or the stationary heater is run-

ning.

If you leave your foot on the brake pedal when

driving, the brake system may overheat.

&

WARNING Risk of skidding and of an acci-

dent due to shiꢀing down on slippery road

surfaces

#

Open a window on the side of the vehicle

facing away from the wind to ensure an

adequate supply of fresh air.

This increases the braking distance and the

brake system can even fail.

#

If you shiꢀ down on slippery road surfaces to

increase the engine braking eꢂect, the drive

wheels may lose traction.

Never use the brake pedal as a footrest.

#

Do not depress the brake pedal and the

accelerator pedal at the same time while

driving.

&

WARNING Risk of accident and injury due

to being under the inꢄuence of alcohol

and drugs while driving

#

Do not shiꢀ down on slippery road surfa-

ces to increase the engine braking

eꢂect.

Drinking and driving and/or taking drugs and

driving are very dangerous combinations. Even

a small amount of alcohol or drugs can aꢂect

your reꢄexes, perceptions and judgment.

*

NOTE Engine damage due to excessively

high engine speeds

The engine will be damaged if you drive with

the engine in the overrevving range.

Driving and parking

134

#

Do not drive with the engine in the over-

revving range.

*

NOTE Damage to the catalytic converter

due to non-combusted fuel

NOTE Damage to the vehicle due to not

observing the maximum permitted head-

room clearance

The engine is not running smoothly and is mis-

ꢃring.

*

NOTE Wearing out the brake linings by

continuously depressing the brake pedal

If the vehicle height is greater than the maxi-

mum permitted headroom clearance, the roof

and other parts of the vehicle may be dam-

aged.

Non-combusted fuel may get into the catalytic

converter.

#

Do not depress the brake pedal continu-

ously whilst driving.

#

Only depress the accelerator pedal

slightly.

#

Observe the signposted headroom clear-

ance.

To use the braking eꢂect of the engine,

shiꢀ to a lower gear in good time.

#

Have the cause rectiꢃed immediately at

a qualiꢃed specialist workshop.

#

If the vehicle height is greater than the

permitted headroom clearance, do not

enter.

*

NOTE Damage to the drivetrain and

engine when pulling away

*

NOTE Reduced battery life due to frequent

short-distance trips

#

Observe the changed vehicle height with

add-on roof equipment.

#

Do not warm up the engine while the

vehicle is stationary. Pull away immedi-

ately.

The 12 V battery may not be suꢁciently

charged when the vehicle is used only for

short-distance trips. This reduces the life of

the battery.

Notes on driving with a roof load, trailer or fully

laden vehicle

When driving with a loaded roof luggage rack or

trailer as well as with a fully laden or fully occu-

pied vehicle, the vehicle's driving and steering

characteristics change.

#

Avoid high engine speeds and driving at

full throttle until the engine has reached

its operating temperature.

#

Drive longer distances regularly to

charge the battery.

You should bear the following in mind:

To remove salt build-up:

Notes on driving through water on the road sur-

face

Water which has entered into the vehicle can

damage the engine, electrics and transmission.

R

Do not exceed the permissible roof load and

towing capacity. Also observe the technical

data in the printed Operator's Manual.

Brake occasionally while paying attention to

the traꢁc conditions

R

Carefully depress the brake pedal at the end

of the journey and when starting the next jour-

ney

Water can also enter the air intake of the engine

and cause engine damage.

R

Evenly distribute the roof load, and place

heavy objects at the bottom. Also comply with

the notes on loading the vehicle

(/ page 100).

Observe the following if you must drive through

water:

Notes on hydroplaning

Hydroplaning can take place once a certain

amount of water has accumulated on the road

surface.

R

The water, when calm, may only reach the

lower edge of the vehicle body.

Drive attentively, and avoid suddenly pulling

away, braking and steering as well as rapid

cornering.

R

Drive at a maximum speed of 6 mph

(10 km/h); water can otherwise enter the

vehicle interior or engine compartment.

Observe the following notes during heavy precipi-

tation or in conditions in which hydroplaning may

occur:

Notes on driving on salt-treated roads

The braking eꢂect is limited on salt-treated roads.

R

Vehicles traveling in front, or oncoming vehi-

cles, can create waves which may exceed the

maximum permissible depth of the water.

R

Reduce speed

Therefore, observe the following notes:

R

Avoid tire ruts

Due to salt build-up on the brake discs and

brakepads, the braking distance can increase

considerably or result in braking only on one

side

R

Avoid sudden steering movements

The braking eꢂect of the brakes is reduced aꢀer

fording. Brake carefully while paying attention to

the traꢁc conditions until braking power has been

fully restored.

R

Brake carefully

Also observe the notes on regularly checking

wheels and tires (/ page 292).
