I START ENGINE STOPI button and also press the
brake pedal.
A WARNING
- Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You may need to
use more force when braking or steering.
Because you cannot brake and steer as you
usually would, this could lead to accidents
and serious injuries.
- If you leave the vehicle, switch the ignition
off and take the vehicle key with you . Other­
wise, the engine could be started or electri­
cal equipment such as the power windows
could be operated. This can lead to serious
injury.
- For safety reasons, always park the vehicle
with the selector lever in the P position .
Otherwise, there is the risk that the vehicle
could roll unintentionally.
0 Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the engine is
switched off and there is a risk of damaging
the engine. For this reason, let the engine run
at idle for approximately two minutes before
shutting it off .
(D Tips
For up to 10 minutes after stopping the en ­
gine, the radiator fan may turn on again auto­
matically or it may continue to run (even if
the ignition is switched off) for the following
reasons:
- The coolant temperature is increasing due
to trapped heat.
- If the engine is warm and the engine com­
partment also heats up from strong sun­
light.

The selector lever position that is engaged is
shown in the instrument cluster display .
P- Park
T his selector l ev er position prevents the vehicle
from rolling. You can only sh ift into Park when
the vehicle is
stationary ¢.&. .
To shift in and out of the P selector lever posi­
tion, press the interlock button in the selector
lever
while pressing the brake pedal. This only
works when the ignition is turned on.

stationary and the engine is running at idle
speed ¢.&. .
To select the R se lector lever position, press t he
interlock button
while pressing the brake peda l
at the same time. The back-up lights switch on in
the R position if the ignition is switched on .
N -Neutral
The transm iss ion is in idle in this pos it ion ¢,&. .
DIS -Normal pos iti on for d riv ing forward
In the D/S selector lever pos ition, the transm is ­
sion can be ope rated either in the normal D mode
or in the S sport mode . T o select the S sport
D rivi ng
mode, pull the selector lever back briefly. Pulling
the lever back again will select the normal D
mode. The instrument cluster d isp lay shows the
selected driving mode.
In the
n o rmal mode "D", the transmission auto ­
matically selects the suitable gear ratio .
It de­
pends on engine load, vehicle speed and driving
style.
Se lect the
sport mode "S " for sporty driving. The
vehicle makes fu ll use of the engine's power.
Sh ift ing is more not iceable when accelerating .
To move from selecto r lever pos ition N to D, you
must press the brake pedal and the vehicle must
be traveling less than 1 mph (2 km/h) or be sta­
t ionary ¢.&. .
A WARNING
----
-The vehicle can roll even if the ignition is
sw itched off.
- Never se lect R or P while driving, because
this increases the risk of an accident.
- Power is still transmitted to the wheels
when the engine is running at idle . To pre­
vent the vehicle from "creeping", you must keep your foot on the b rake in all selector
lever positions (except P) when the engine is
r u nning. Otherwise, this inc reases the risk
of an acc ident.
- Do not inadvertently p ress the accelerator
pedal when the vehicle is stopped if a gea r is
engaged. O therwise the ve hicle will start to
move immed iate ly, even if the parking brake
is set . This could result in a crash.
- To decrease the r is k of an accident, these­
lecto r lever mus t be in the P pos ition and
the parking brake must be set before open ­
ing the hood and working on a running en­
g ine. A lways read and follow the applicable
warn ings

A WARNING
-The veh icle can roll even if the ignition is

-Never leave your vehicle with the engine
runn ing wh ile in gear .
-Do not press the accelerator pedal when

-Please note that a sma ll amount of power is
t ransmitted if the vehicle is stopped tempo­
ra rily while in t he D/S or R selector lever po ­

It could cause a crash.
-Be fore dr iv ing dow n a steep s lope, red uce
yo ur speed and shift in to a lower gear with
"ti ptro n i c" .
-Do not ride the brakes o r press the brake
peda l too often or too long w hen driving
down hill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases brak-
Driving
ing distance or causes comp lete fai lure of
the brake system.
-If you m ust stop on an incline, a lways ho ld
the vehicle in place wit h the foot brake or
parking brake to prevent it from rolling
back .
-Never hold the vehicle on an incline with a
slipp ing clutch. The clutch opens automati­
cally when it becomes too hot from the
overload .

the clutch is overloaded .
@ Note
-When stopping on an incl ine, do not try to
hold the ve hicle in place by pressing the ac­
celerator peda l wh ile a d riving gear is se­
lected. This ca n cause t he transmission to
over heat a nd can damage it. Se t the park ing
bra ke or p ress the brake pedal to p revent
t he vehicle from rolling.
-Allowing the vehicle to roll when t he engine
is stopped will damage the transmission be ­
cause it is not lubricated.

Hill descent control
The hill descent control system assists the driver
when driving down hills .
Hill descent control is act ivated when the selec­
tor leve r is in the D or S position and yo u press
the brake peda l. The transmission a utomatica lly
selects a gear that is suitable for the hi ll. Hill de ­
scent control tries to maintain the speed ach ­
ieved at the time of braking, w ith in physical and
technical lim itations . If may still be necessary to
adjust the speed w ith the brake pedal.
Hi ll descent control switches off once the hill lev-
els out or you press the accelerator pedal.

Driving
On vehicles with a cruise control system*
¢ page 84, hill descent control is also activated
when the speed is set.
A WARNING
Hill descent control cannot overcome physical
limitations, so it may not be able to maintain
a constant speed under all condit ions. Always
be ready to apply the brakes.
