WARNING
With the drive system inactive, there is no
power assistance for the brake and steering
systems. In this case, it is important to
keep in mind that a considerably higher
degree of effort is necessary to brake and
steer the vehicle. Adapt your driving
accordingly. G
WARNING
Vehicle movement can cause serious per-
sonal injury. Therefore, always do the fol-
lowing before exiting and leaving the
vehicle:
R Keep right foot on the brake pedal.
R Engage the parking brake.
R Move the gear selector lever to park
position P.
R Slowly release the brake pedal.
R When parked on an incline, always turn
the front wheels towards the curb.

and remove the key from the starter
switch.
R Take the key with you and lock the vehicle
when leaving.
X Properly stop and park the vehicle.

ces the braking effect of the electric
motor.
In overrun or braking mode, the motor's
braking effect may therefore be reduced or
may not be present at all.
As a result of the reduced engine braking
effect, you may cause an accident and
injure yourself or others.
Compensate for the reduced engine braking
effect by pressing the brake pedal accord-
ingly, as required.
Using the steering wheel paddle shifters *,
you can increase or decrease the recuper-
ation in overrun phases. Recuperation
takes place when you release the acceler-
ator pedal. The electric motor will then be
used as a generator and energy will be
regained while driving. The regained
energy is stored in the high-voltage bat-
tery. High recuperation decelerates your
vehicle stronger.
In overrun phases, there are three levels of
recuperation:
R no recuperation (level 0, coasting)
R moderate recuperation (level 1)
R high-level recuperation (level 2)
The amount of recuperation in overrun
mode is displayed in the power gauge
(Y page 81).
The set mode for recuperation is shown in
the recuperation display (Y page 84).
When you switch on the ignition, level 1 is
automatically preset. 0043

Use the different levels 0 to 2 for condi-
tions as described below: Level 0 Driving without frequent
breaking. No sharp bends on
the road ahead.
Maximum kinetic energy
remains for the vehicle.
Level 1 Normal driving, standard set-
ting.
Level 2 Sporty driving.
The break pedal has to be
depressed less often, as the
deceleration due to recuper-
ation is higher than in
level 1.
The energy efficiency is sub-
stantially higher than if the
vehicle is decelerated by
depressing the brake pedal.
At levels 1 and 2 the vehicle can be step-
lessly decelerated by depressing the brake
pedal.80

Cruise control*
The cruise control maintains the speed you
set for your vehicle automatically. On
downhill grades, the cruise control does
not brake the vehicle via the brake system.
The cruise control can only use the braking
power of the engine. You must apply the
brakes yourself in order to reduce the
vehicle speed. The cruise control will then
be canceled. G
WARNING
The cruise control is a convenience system
designed to assist the driver during vehi-
cle operation. The cruise control cannot
take road, traffic, and weather conditions
into account. The driver is and must always
remain responsible for the vehicle’s speed
and for safe brake operation. Do not use the cruise control

WARNING
To help avoid personal injury during a col-
lision or sudden maneuver, exercise care
when storing objects in the vehicle. Put
luggage or cargo in the cargo compartment
if possible. Do not pile luggage or cargo
higher than the seat backrests.
Keep compartment lids closed. This will
help to prevent stored objects from being

pants during

R a change of direction
R an accident
Do not store objects under the driver’s seat.
Objects stored under the driver’s seat can
slide forward into driver’s foot well during
braking and get caught between or beneath
the pedals. This could restrict your ability
to brake or accelerate and could lead to
accidents and injury.

ride comfort, wear unevenly, increase
stopping distance, and result in sudden
deflation (blowout) because they are more
likely to become punctured or damaged by
road debris, potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the
Tire and Loading Information placard on
the driver’s door B‑pillar. Overloading the
tires can overheat them, possibly causing
a blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.
Your vehicle is equipped with the Tire and
Loading Information placard located on
the driver’s door B‑pillar (Y page 134).
The tire inflation pressure should be
checked regularly. Only adjust the tire
inflation pressure on cold tires. The tires
can be considered cold if the vehicle has
been parked for at least 3 hours or driven
less than 1 mile (1.6 km). Depending on the
ambient temperature, the driving speed
and the tire load, the tire temperature
changes. When the tire temperature
changes by 18¦ (10¥), the tire inflation
pressure will change by approximately
10 kpa (0.1 bar, 1.5 psi). Keep this in mind
when checking tire inflation pressure on
warm tires and adjust the tire pressure
only if the tire inflation pressure is too
low for the current operating conditions.
If you check the tire inflation pressure
when the tires are warm, the reading will
be higher than the cold reading. This is
normal. Do not let air out to match the
specified cold tire inflation pressure.
Otherwise, the tire will be underinflated.
Follow recommended cold tire inflation
pressures listed on Tire and Loading
Information placard on the driver’s door
B‑pillar.
Keeping the tires properly inflated pro-
vides the best handling, tread life and rid-
ing comfort. In addition to the Tire and Loading Infor-
mation placard on the driver’s door B‑pil-
lar, also consult the tire inflation pres-
sure label (if available) on the inside of
the filler flap for any additional informa-
tion pertaining to special driving situa-
tions. For more information, see “Impor-
tant notes on tire inflation pressure”
(Y
page 129).

mation placard example are for illus-
tration purposes only. Tire data are spe-
cific to each vehicle and may vary from
data shown in the following illustration.
Refer to Tire and Loading Information
placard on vehicle for actual data spe-
