Diesel engine: On rising g ra dients of 10% or
more, do not drive faster than 20 mph (30
km/h) in 1st gear or 30 mph (50 k m/h) in
2nd gear; with autom atic transmission, d o
not exceed 25 mph (40 k m/h) in position 1.
When driving downhill, towing a caravan/
trailer subjects the brakes to a heavier load
than norm al. For this reason, select the
same gear as when driving uphill and drive
at a similar speed. With automa tic
transm ission, engage position 3, 2 or
even 1.
Select D again as soon as driv ing
conditions permit.
Ea sy tronic 3 in autom atic mode or
automatic transmission 3 in D will
automatically select the driving
programme with optimum engine b ra king
effect.
If full-on braking is required , depress the
brake pedal as hard as possib le.
Remem ber that the braking distance for
vehic les towing caravans/trailers w ith a nd
without brake is a lways grea ter than that
for vehicles not towing a caravan/trailer.
Starting on inclines
For vehicles with manual transm ission, the
most fav ourable eng ine speed when
starting off on an incline is between 2500
and 3000 rpm for petrol engines and
between 2000 and 2500 rpm for diesel
engines. Hold engine rp m constant,
engage clutch gradually (let slip), release
brake and open throttle. If possible, the
engine speed should not drop during this
proc edure.
O n vehicles with Easytronic 3 in autom atic
mode or automatic transmission 3 in D, it is
sufficient to apply full throttle.
Before starting off under ex treme
conditions (high combination weight,
mountainous terrain w ith steep inclines),
switch off all unnecessary electrical loads
(e.g. heated rear window, air conditioning
system 3, heated front seats 3).
