son.

height. Uns uperv ised or careless seat ad­
justment can p inch f ingers or hands, wh ich
increases the risk of injury.
- T he front seat backres ts m ust not be re­
clined too far back when driving, because

Driving
General information
Breaking in
A new vehicle must be broken in for the first 1,000 mi les (1,500 km). Do not dr ive at speeds
t hat will exceed 2/3 of the max imum pe rm itted
engine speed (RPM) for the first 600 miles
(1,000 km), and avoid fu ll acceleration during
this period . You may gradually start increasing
the RPM and the speed between 600 miles (1,000 km) and 1,000 miles (1,500 km) .
During the first hours of use, the engine has a
higher internal friction than later on when all
moving parts have settled into place with each
other.
How the vehicle is driven d uring the first 1,000
miles (1 ,500 km) a lso affects the engine quality .
Drive at moderate engine speeds after the initial
break-in per iod, part icu larly when running a cold
eng ine . Th is will reduce eng ine wear and improve
the m ileage .
Do not drive at too
low of an engine speed (RPM).
Shift down if the engine stops running "smooth­ ly". Extremely high eng ine speeds are automati­
cally reduced .
Reducing the risk of vehicle damage
@ Note
When driving on poo r roads, by cu rbs and on
s teep ramps, make su re t hat low-hang ing
compone nts such as the spo ile r and exha ust
system do not come into contact with these
or they could be damaged. This especially ap ­
plies to vehicles with low ground clearance
and veh icles that are heavily loaded.
Warming up/cooling down
Applies to: RS models
By warming up/cooling down the engine carefu l­
ly, you can help reduce unnecessary stra in o n
your veh icle when driving in a sporty sty le .
72
The tires only reach t heir full road ho ld ing capa ­
bility once they have warmed up under load.
Yo ur vehicle also has an afte r-run cooli ng fea ­
tu re . Howeve r, cooling down is st ill import ant.
The eng ine and t he brakes as we ll as the exhaust
system and the transmission become very hot
when driving in a sporty style. Before you shut
the veh icle off, you should cool down the vehicle
by driving a few miles at low speeds with light ac­
ce leration .
Driving through water on roads
Note the following to reduce the risk of veh icle
damage when dr iving throug h wate r, fo r example
o n flooded roads:
-The water must not be any higher than the bot ­
tom of the vehicle body .
-Do not drive faster than walk ing speed .
A WARNING
After driving thro ugh water or m ud, the effec­
tiveness of t he b rakes may be reduced due to
mo istu re o n the bra ke rotors and brake pads.
A few ca reful br ake app lica tions sho uld d ry
off the bra kes and restore the fu ll b raking ef ­
fect.
@ Note
-Vehicle components such as the e ng ine,
t ra nsmiss ion, sus pens io n or elect rical sys ­
tem can be severely damaged by d riving
throug h water.
-Alw ays sw itch the S tart/Stop system* o ff

(j) Tips
-De ter mine the dep th before dr iving throug h
w ate r.
-Do not stop the vehi cle, d rive in reverse or
switch t he e ngine off whe n driving through
water .
-Keep in mind that o ncom ing vehicles may
c re ate w aves th at r aise the wa ter level and
make i t too deep for yo ur vehicle to drive
throug h safe ly.
