Four-C
R-models are equipped with the Four-C (Continuously Controlled Chassis Concept) system.
This system is based on a number of sensors that continuously monitor factors such as the car's lateral and vertical
movements, speed, and movements of the wheels. The sensors receive data up to 500 times per second, which is used
to provide extremely fast and precise adjustment of each shock absorber. The system adjusts the stiffness of the shock
absorbers approximately 100 times per second.
The buttons in the center of the dashboard (see the illustration above) can be used at any time to switch between three
driving modes: Comfort, Sport, or Advanced sport.
The system then adjusts the stiffness of the shock absorbers accordingly, for example when the type of road changes,
or if the driver wishes to change driving style. This adjustment takes place instantaneously.
The effect of pressure on the throttle pedal is linked to the selected mode, where the Advanced sport setting provides
the most immediate throttle response.
Comfort
The Comfort mode chassis setting offers the greatest amount of shock absorption and the softest ride. This mode is
recommended for long-distance driving, or when driving in slippery conditions.
If Comfort mode was selected when the engine was switched off, this mode will still be active when the engine is
restarted.
Sport
In this mode, shock absorption is stiffer to reduce the car's body sway during cornering and to provide more immediate
steering response.
If this setting was selected when the engine was switched off, Sport mode still will be active when the engine is
restarted.
Advanced sport
In this mode, movement of the shock absorbers is minimal, response from pressure on the throttle pedal is more direct,
and body sway in curves or when cornering is sharply reduced.
If Advanced sport mode was selected when the engine was switched off, Sport mode will be active when the engine
is restarted.

Speed-sensitive power steering
(Option on certain models)
With this feature, the steering is most responsive at lower speeds to make parking, driving in city traffic, etc., easier.
The effect of the power steering diminishes as you accelerate for greater stability at highway speeds.
Weight distribution affects handling
At the specified curb weight your car has a tendency to understeer, which means that the steering wheel has to be
turned more than might seem appropriate for the curvature of a bend. This ensures good stability and reduces the risk
of rear wheel skid. Remember that these properties can alter with the vehicle load. The heavier the load on the rear of
the vehicle (e.g., heavily loaded (max. 220 lbs, 100 kg) cargo area or when towing a trailer, the less the tendency to
understeer.
pg. 102 Points to remember
Cooling system
The risk for engine overheating is greatest, especially in hot weather, when:
Towing a trailer up steep inclines for prolonged periods at wide open throttle and low engine rpm.
Stopping the engine suddenly after high speed driving (so-called "after-boiling" can occur).
To avoid overheating, the following rules should be followed:
Do not drive for prolonged periods at engine speeds above 4500 rpm if you are towing a trailer in hilly terrain.
Reduce speed when towing a trailer up long, steep inclines. The risk of overheating can be reduced by switching off
the air conditioning system for a short time.
Do not let the engine idle unnecessarily for prolonged periods.
Do not mount auxiliary lamps in front of the grill.
When the risk of overheating is imminent, or in the event of overheating (the temperature gauge goes repeatedly into,
or stays continually in, the red section), the following precautions should be taken:
Switch off the air conditioning system.
Pull off the road, away from traffic, stop the car and put the gear selector into neutral.
Switch the heater to full (maximum) position. Increase the engine speed to approx. 2000 rpm (twice idling speed)
until the temperature begins to drop.
WARNING!
Do not remove coolant expansion tank cap. The coolant will be extremely hot.
If necessary, see page 148
and 151 for information on checking and topping-up the coolant level.
CAUTION: Drive slowly and carefully if going through standing water (i.e. flooded roadways, etc.). Damage to the
engine could result if excess water is drawn in through the air intake system. Never drive the vehicle in water deeper
than 1 foot (300 mm). See the flood warning on page 7
.
WARNING!
Driving with the tailgate open : Driving with the tailgate open could mean that poisonous exhaust gases enter the
passenger compartment.
If the tailgate must be kept open for any reason, proceed as follows:
- Close the windows.
- Set the ventilation system to air flow to floor, windshield and side windows and blower control to its highest

If this occurs, reduce vehicle speed to a maximum of 50 mph (80 km/h). The vehicle can be driven approximately 50
miles (80 km), or somewhat farther if the vehicle is not heavily loaded. The tire should be replaced as soon as
possible.
Hard braking and sudden steering maneuvers should be avoided.
In certain cases, it may be difficult to see which self supporting run flat tire is defective. To determine which tire is
damaged, check the inflation pressure of all four tires.WARNING!
• Only specially trained persons should mount self supporting run flat tires.
• If self supporting run flat tires are mounted, the vehicle must be equipped with a Tire Pressure Monitoring System.
• After a low pressure warning has been displayed, do not exceed 50 mph (80 km/h).
• Avoid severe cornering and hard braking, and minimize the distance traveled before replacing the self supporting
run flat tire.
• Self supporting run flat tires cannot be repaired. They must be replaced if damaged or punctured.
pg. 120 Wheels and tires
Tire designations
Federal law mandates that tire manufacturers place standardized information on the sidewall of all tires (see the
illustration).
The following information is listed on the tire sidewall:
The tire designation (the following figures are examples of a tire designation):
1. 215: the width of the tire (in millimeters) from sidewall edge to sidewall edge. The larger the number, the wider the
tire.
2. 65: The ratio of the tire's height to its width.
3. R: Radial tire.
4. 15: The diameter of the wheel rim (in inches).
5. 95: The tire's load index. In this example, a load index of 95 equals a maximum load of 1521 lbs (690 kg).
6. H: The tire's speed rating, or the maximum speed at which the tire is designed to be driven for extended periods of

Charge air cooler (Intercooler)
Turbocharged engines employ a turbo-compressor to force air into the engine inlet manifold and a charge air cooler to
cool the compressed inlet air. The resulting increase in air flow raises pressure in the intake manifold and increases
engine power over that developed by A normally-aspirated engine. The charge air cooler (which resembles a radiator)
is located between the turbo-compressor and inlet manifold.
