The GEM switches the direction indicators and the
direction indicator side repeaters on.
The GEM sends a signal to the instrument cluster
via the CAN bus to switch on the relevant turn
indicator and the acoustic signal.
The signals from the hazard flasher switch and
from the multifunction switch are transmitted to the
GEM via a wiring connection.
The turn signals and the warning lamp flash at a
specified frequency and, in the case of failure of a
turn signal, the frequency is doubled.
The turn signal lamps also have a one-touch lane
change function. If the multifunction lever is
pressed just slightly then the relevant turn signal
lamp is actuated 3 times by the GEM.
Interior lighting
Depending on the vehicle specification, the interior
lighting includes:
• Left and right-hand footwell lamps
• Overhead lights at front and rear
Depending on the vehicle specification, the
switchable interior lighting includes:
• Map lights
• Mirror lights in sun visors
• Glove compartment lamp
• Luggage compartment lamp
The front and rear overhead lights are switched on
by the GEM. The interior lighting is switched on if one of the
following conditions is satisfied:
One of the vehicle's doors is opened.
The ignition key is in the "0" or "I" position and the
vehicle is unlocked.

Rear Drive Axle and Differential – System Operation andComponent Description
System Operation
General Information
The powertrain with all-wheel drive consists of the
following main components:
• engine
• transaxle with front axle differential
• transfer box
• halfshafts and driveshafts
• Haldex clutch
• rear axle differential
The Haldex clutch guarantees continuous variable
torque transmission to the rear axle under all
driving conditions. The Haldex clutch reacts
immediately and equally quickly with slow or fast
wheel slip.
A difference in angle of rotation of 90° between the
input and output shafts is required to build up
maximum pressure at the multi-plate clutch or to
transmit maximum torque.
The advantage of vehicles with all-wheel drive is
that they distribute the drive between all four
wheels. They therefore have a higher tractive
power. They feature improved cornering behaviour,
as the grip at all four wheels can be better utilised.
Thus, the wheels contribute to a greater degree
towards cornering stability.
The engine torque is transmitted from the transfer
box to the rear axle via a driveshaft. The driveshaft
is flange-mounted to the input side of the Haldex
clutch.
Driving situations
Pulling away and accelerating
• When pulling away and accelerating, as muchall-wheel drive as necessary must be available
immediately in the short-term. During
acceleration, the electronic system detects slip
at the front axle. This slip is counter-controlled
and thus the propulsive force optimally
distributed to the two axes.
Cornering • A sporty driving style, in particular dynamic
cornering, demands stable cornering behaviour.
The all-wheel system distributes the propulsive
force to all four wheels and by so doing boosts
the high cornering forces so that the vehicle
makes optimum contact with the road surface.
Snow and black ice
• Snow and black ice require particularly high grip. Under these conditions, the Haldex clutch
always distributes the propulsive force to the
axle with the better traction. The all-wheel
system reacts intelligently and quickly to all
driving situations.
Trailer operation
• When driving with a trailer, the trailer weight (support load) is transmitted to the rear axle via
the towbar. This reduces the load on the front
wheels, which means they can slip. The
electronic system detects this difference and
distributes most of the propulsive force to the
rear axle.

4. Remove the vacuum hose from the brakebooster. Manifold vacuum should be available
at the brake booster end of the hose with the
engine at idle speed and the transaxle in the
NEUTRAL position. Make sure that all unused
vacuum outlets are correctly capped, hose
connectors are correctly secured and vacuum
hoses are in good condition. When it is
established that manifold vacuum is available
to the brake booster, connect the vacuum hose
to the brake booster and repeat Step 3. If no
downward movement of the brake pedal is felt,
install a new brake booster.
5. Operate the engine a minimum of 10 seconds at approximately 1200 rpm. Stop the engine and
let the vehicle stand for 10 minutes. Then, apply
the brake pedal with approximately 89 N (20 lb)
force. The pedal feel (brake application) should
be the same as that noted with the engine
operating. If the brake pedal feels hard (no
power assist), install a new vacuum check valve
and then repeat the test. If the brake pedal still
feels hard, install a new brake booster. If the
brake pedal movement feels spongy, bleed the
brake system. REFER to: (206-00 Brake System
- General Information)
Brake System Bleeding (General Procedures),
Brake System Pressure Bleeding (General
Procedures),
Component Bleeding (General Procedures).
Brake Master Cylinder
Usually, the first and strongest indicator of anything
wrong with the braking system is a feeling through
the brake pedal. In diagnosing the condition of the
brake master cylinder, check pedal feel as
evidence of a brake concern. Check for the red
brake warning indicator illumination and the fluid
level in the master cylinder reservoir.
Normal Conditions
The following conditions are considered normal
and are not indications that the brake master
cylinder is in need of service.
– Modern brake systems are not designed to
produce as hard a pedal effort as in the past.
Complaints of light pedal efforts should be compared to pedal efforts of another vehicle, of
the same model and year.
– During normal operation of the brake pedal, the fluid level in the reservoir will rise during brake
pedal application and fall during release. The
net fluid level (i.e., after brake pedal application
and release) will remain unchanged.
– A trace of brake fluid will exists on the brake booster shell below the master cylinder
mounting flange. This results from the normal
lubricating action of the master cylinder bore
end seal.
– The fluid level will fall with brake shoe and lining wear.
Abnormal Conditions
NOTE: Prior to performing any diagnosis, make
sure the brake system warning indicator is
functional.
Changes in brake pedal feel or travel are indicators
that something could be wrong with the braking
system. The diagnostic procedure and techniques
use brake pedal feel, warning indicator illumination
and low brake fluid level as indicators in diagnosing
braking system concerns. The following conditions
are considered abnormal and indicate that the
brake master cylinder is in need of service.
– The brake pedal goes down fast. This could be caused by an external or internal leak.
– The brake pedal eases down slowly. This could be caused by an external or internal leak.
– The brake pedal is low and or feels spongy. This condition may be caused by no fluid in the brake
master cylinder reservoir, reservoir cap vent
holes clogged or air in the hydraulic system.
– The brake pedal effort is excessive. This may be caused by a bind or obstruction in the pedal
or linkage, clogged fluid control valve or
insufficient booster vacuum.
– The rear brakes lock up during light pedal force. This may be caused by incorrect tire pressures,
grease or fluid on the brake shoes and linings,
damaged brake shoes and linings, incorrectly
adjusted parking brake, or damaged or
contaminated brake pressure control valves.
– The brake pedal effort is erratic. This condition could be caused by a brake booster malfunction,
extreme caliper piston knock back or incorrectly
installed brake shoes and linings.
– The red brake warning indicator is ON. This may be caused by low fluid level, ignition wire routing
