The engine can only be started with  
the lever in position P or N. When  
position N is selected, press the brake  
pedal or apply the parking brake  
before starting.  
Do not accelerate while engaging a  
gear. Never depress the accelerator  
pedal and brake pedal at the same  
time.  
If a higher gear is selected when  
Parking  
vehicle speed is too low, or a lower  
gear when vehicle speed is too high,  
the shift is not executed. This can  
cause a message in the Driver  
Information Centre.  
Apply the parking brake and engage  
P.  
The ignition key can only be removed  
when the selector lever is in position  
P.  
In manual mode, no automatic  
shifting to a higher gear takes place  
at high engine revolutions.  
Manual mode  
When a gear is engaged, the vehicle  
slowly begins to creep when the  
brake is released.  
Gear shift indication  
The symbol R or S with a number  
beside it is indicated when  
gearshifting is recommended for fuel  
saving reasons.  
Shift indication appears only in  
manual mode.  
Engine braking  
To utilise the engine braking effect,  
select a lower gear in good time when  
driving downhill, see manual mode.  
Rocking the vehicle  
Rocking the vehicle is only  
permissible if the vehicle is stuck in  
sand, mud or snow. Move the selector  
lever between D and R in a repeat  
pattern. Do not race the engine and  
avoid sudden acceleration.

Interruption of power supply  
In the event of an interruption of  
power supply, the selector lever  
cannot be moved out of the P  
position. The ignition key cannot be  
removed from the ignition switch.  
Kickdown  
Pressing down the accelerator pedal  
beyond the kickdown detent will lead  
to maximum acceleration  
independent of the selected driving  
mode. The transmission shifts to a  
lower gear depending on engine  
speed and shifts to a higher gear at  
high engine revolutions.  
If the vehicle battery is discharged,  
start the vehicle using jump leads

If the vehicle battery is not the cause  
of the fault, release the selector lever.  
1. Apply the parking brake.  
3. Insert a small stick (e.g. a pen or  
screw driver) into the opening  
near the selector lever. Push  
down the stick vertically and move  
the selector lever out of P. If this  
position is engaged again, the  
selector lever will be locked again.  
Have the cause of the power  
supply interruption remedied by a  
workshop.

When clutch slip is detected for a  
specific time, the engine power will be  
reduced. A warning is displayed in the  
Driver Information Centre. Release  
the clutch.  
Manual transmission  
Brakes  
The brake system comprises two  
independent brake circuits.  
If a brake circuit fails, the vehicle can  
still be braked using the other brake  
circuit. However, braking effect is  
achieved only when the brake pedal  
is depressed firmly. Considerably  
more force is needed for this. The  
braking distance is extended. Seek  
the assistance of a workshop before  
continuing the journey.  
Caution  
It is not advisable to drive with the  
hand resting on the selector lever.

To engage reverse, depress the  
clutch pedal and then press the  
release button on the selector lever  
and engage the gear.  
If the gear does not engage, set the  
lever to neutral, release the clutch  
pedal and depress again; then repeat  
gear selection.  
disappears once the brake pedal has  
been depressed once or twice.  
Braking effect is not reduced, but  
braking requires significantly greater  
force. It is especially important to bear  
this in mind when being towed.  
Control indicator R 3 109.  
Do not slip the clutch unnecessarily.  
Antilock brake system  
When operating, depress the clutch  
pedal completely. Do not use the  
pedal as a foot rest.  
Antilock brake system (ABS)  
prevents the wheels from locking.

Driving and operating  
ABS starts to regulate brake pressure  
as soon as a wheel shows a tendency  
to lock. The vehicle remains

steerable, even during hard braking.  
ABS control is made apparent  
through a pulse in the brake pedal  
and the noise of the regulation  
process.  
For optimum braking, keep the brake  
pedal fully depressed throughout the  
braking process, despite the fact that  
the pedal is pulsating. Do not reduce  
the pressure on the pedal.  
If there is a fault in the ABS, the  
wheels may be liable to lock due  
to braking that is heavier than  
normal. The advantages of ABS  
are no longer available. During  
hard braking, the vehicle can no  
longer be steered and may  
swerve.  
Have the cause of the fault remedied  
by a workshop.  
After starting off, the system performs  
a self-test which may be audible.  
9 Warning  
Parking brake  
Always apply parking brake firmly  
without operating the release  
button, and apply as firmly as  
possible on a downhill or uphill  
slope.  
To release the parking brake, pull  
the lever up slightly, press the  
release button and fully lower the  
lever.  
9 Warning  
Before leaving the vehicle, check  
parking brake status. Control  
indicator R (manual parking  
brake) or m (electrical parking  
brake) illuminate constantly when  
parking brake is applied.  
Control indicator u 3 110.  
Adaptive brake light  
During full braking, all three brake  
lights flash for the duration of ABS  
control.

Do not operate electric parking brake  
system too often without engine  
running as this will discharge the  
vehicle battery.  
Dynamic braking when vehicle is  
moving  
When the vehicle is moving and the  
switch m is kept pulled, the electric  
parking brake system will decelerate  
the vehicle, but will not apply  
statically.  
To reduce the operating forces of  
the parking brake, depress the  
foot brake at the same time.  
Control indicator R 3 109.  
Releasing  
Switch on ignition. Keep foot brake  
pedal depressed and then push  
switch m. If control indicator m  
extinguishes, electric parking brake is  
released.  
Electric parking brake  
As soon as the switch m is released,  
dynamic braking will be stopped.  
Automatic applying  
If the vehicle is equipped with  
automatic transmission and adaptive  
cruise control is active, electric  
parking brake is applied automatically  
when vehicle is stopped by the  
system for more than 2 minutes.  
Drive away function  
Vehicles with manual transmission:  
Depressing the clutch pedal and then  
slightly releasing the clutch pedal and  
slightly depressing the accelerator  
pedal releases the electric parking  
brake automatically. This is not  
possible when switch m is pulled at  
the same time.  
Parking brake releases automatically  
after moving off.

Pull the switch m. If control indicator  
m illuminates, electric parking brake  
is applied.  
The electric parking brake can always  
be activated, even if the ignition is off.  
Vehicles with automatic transmission:  
Engaging D and then depressing the  
accelerator pedal releases the  
electric parking brake automatically.  
This is not possible when switch m is  
pulled at the same time.  
When the vehicle is not moving, the  
electric parking brake might be  
applied automatically. This is done to  
check the system.

Fault  
Hill start assist  
Ride control systems  
Failure mode of electric parking brake  
is indicated by a control indicator j  
and by a vehicle message which is  
displayed in the Driver Information  
Centre.  
The system helps prevent unintended  
movement when driving away on  
inclines.  
Traction Control system  
The Traction Control system (TC) is a  
component of the Electronic Stability  
Control (ESC).  
When releasing the brake pedal after  
stopping on an incline, brakes remain  
on for further two seconds. The  
brakes release automatically as soon  
as the vehicle begins to accelerate.  
Vehicle messages 3 121.  
TC improves driving stability when  
necessary, regardless of the type of  
road surface or tyre grip, by  
preventing the drive wheels from  
spinning.  
As soon as the drive wheels starts to  
spin, engine output is reduced and  
the wheel spinning the most is braked  
individually. This considerably  
improves the driving stability of the  
vehicle on slippery road surfaces.  
Control indicator m flashes: electric  
parking brake is not fully applied or  
released. When continuously  
flashing, release electric parking  
brake and retry applying.  
Brake assist  
If brake pedal is depressed quickly  
and forcefully, maximum brake force  
is automatically applied.  
Operation of brake assist might  
become apparent by a pulse in the  
brake pedal and a greater resistance  
when depressing the brake pedal.  
Maintain steady pressure on the  
brake pedal as long as full braking is  
required. Maximum brake force is  
automatically reduced when brake  
pedal is released.  
TC is operational after each engine  
start as soon as the control indicator  
b extinguishes.
