drive diagonally across an incline. Drive in
the direction of the incline.
NOTE
Avoid driving on steep slopes if the fuel level
is low. The catalytic converter could be
damaged if the engine does not receive
enough fuel. When driving on extremely
steep slopes, make sure the tank is more
than half full to avoid the risk of breakdown.
Driving in water
The car can be driven through water at a maxi-
mum depth of 40 cm at a maximum speed of
10 km/h. Extra caution should be exercised
when passing through flowing water.
IMPORTANT
Engine damage can occur if water enters
the air filter.
In greater depths, water can enter the trans-
mission. This reduces the lubricating ability
of the oils and shortens the service life of the
systems.
During driving in water, maintain a low speed
and do not stop the car. When the water has
been passed, depress the brake pedal lightly
and check that full brake function is achieved.
Water and mud for example can make the
brake linings wet resulting in delayed brake
function.
NOTE
Clean the electric contacts of the electric
engine block heater and trailer coupling
after driving in water and mud.
IMPORTANT
Do not let the car stand with water over the
sills for any long period of time. This could
cause electrical malfunctions.
In the event of engine stop in water do not
try restart. Tow the car from the water.
Do not overload the battery
The electrical functions in the car load the bat-
tery to varying degrees. Avoid having the igni-
tion key in position II when the engine is turned
off. Use position I instead, as less power is
used. The 12 volt outlet in the cargo area sup-
plies power even when the ignition key is
removed.
Examples of functions that use a lot of power:
•
ventilation fan
•
windscreen wipers
•
audio equipment (high volume)
06 Starting and driving
•
parking lights
Also, be aware of different accessories that
load the electrical system. Do not use functions
which use a lot of power when the engine is
switched off.
If the battery voltage is low, a message appears
on the display. The energy-saving function
shuts down certain functions or reduces the
load on the battery by, for example, slowing the
ventilation fan and switching off the audio sys-
tem. Charge the battery by starting the engine.
