Jeep Grand Cherokee 2009 Class-leading Diesel Performance PDF Reference Guide

Ultimate capability
When you’re equipped with any one of these advanced 4WD systems, greater confidence, wherever you choose to drive, is simply part of the plan. Climb the rockiest hills and plow through the deepest snowdrifts with Quadra-Drive II™. With front and rear Electronic Limited-Slip Differentials (ELSD) that can help transfer up to 100 percent of available torque to any one wheel with traction, this Trail Rated® system provides ultimate traction in the most severe driving conditions. Stay on course with the innovative all-speed traction control built right into the Quadra-Trac II™ Trail Rated system. If slippage is detected, up to 100 percent of the available torque can be routed to the axle with the most traction. Or, shift into low range for even greater performance to conquer challenging conditions off-road. Standard on Laredo, Quadra-Trac I™(1) is a full-time system that operates smoothly, with no driver interaction required. Under normal driving conditions, torque is distributed 48 percent to the front wheels and 52 percent to the rear wheels. If wheel slippage occurs, the integrated traction control system helps transfer torque to those wheels with traction for secure 4WD capability when driving on-road during hazardous weather conditions.

Harnessing 420 hp and 420 lb-ft of torque, the SRT™ 4WD can launch the Grand Cherokee SRT8 from 0-60 mph (0-96 km/h) in under five seconds on wet or dry pavement. Built to handle the burly 6.1L SRT HEMI® V8 engine, this hard-working system provides powerful on- NV245 ACTIVE (QUADRA-TRAC II) road traction; not intended for off-road use.

Jeep Grand Cherokee’s robust Electronic Stability Program (ESP™),(2) Electronic Roll Mitigation, Anti-lock Brake System (ABS) and Brake Assist partner with Trailer Sway Control (TSC) to help you and your trailer load safely reach your destination. With maximum towing power of up to 3266 kilograms (7200 pounds) when properly equipped, Grand Cherokee alternates brake pressure to help reduce trailer sway and improve handling in adverse towing conditions caused by crosswinds and traffic. When the network of ESP sensors detects that you are veering off your intended path, this comprehensive system instantaneously takes action to help keep you moving safely forward. Hill Start Assist (HSA) and Hill Descent Control (HDC) are available features that employ automatic braking and can be helpful when driving in urban as well as off-road areas with steep hills.

Jeep Trail Rated vehicles are designed to perform in a variety of off-road conditions identified by five performance categories: Articulation
The ability to keep tires in contact with the road, providing traction to climb over large obstacles. Ground Clearance The ability to drive over
large obstacles or logs in combination with approach/departure/breakover angles. Manoeuvrability The ability to navigate around obstacles that are tightly situated. Traction The ability to transfer power to the road or trail, along with the ability of the suspension to keep the wheels in contact with the terrain. Water Fording The ability to cross a specific depth of water at a specific speed.

Empowering choices
One of the keys to having fun out there is the ability to choose the engine that’s right for you and everything you’re into. No other vehicle in this class gives you more engine choices than Jeep® Grand Cherokee. More power. More torque. More efficiency. Enjoy them all with Grand Cherokee’s
available 5.7L HEMI® V8 engine. Redesigned for 2009 and featuring VVT and ingenious MDS fuel-saving technology, (1) this new HEMI engine seamlessly transitions to four-cylinder mode when power requirements are reduced. Put your foot down and all 357 hp and 389 lb-ft of torque roar back in a mere 40 milliseconds.

Standard on Laredo and Limited, the venerable 3.7L V6 delivers a fuel-efficient blend of smooth, quiet performance and powerful capability. The available 4.7L V8 engine combines workhorse toughness with flex-fuel versatility. It runs on gas, E85, or any mixture of the two. Either way you’ll be in command of 305 hp and 334 lb-ft of torque. Utilizing some of the same technology featured in its HEMI sibling, this advanced engine incorporates two spark plugs per cylinder and Electronic Throttle Control for optimum smoothness and power throughout its operating range.
Backing its formidable exhaust note with race-bred performance potential, the awesome 6.1L SRT HEMI V8 engine serves up a whopping 420 hp that can launch you and your soon-to-be-impressed guests from 0-96 km/h (0-60 mph) in less than five seconds.

King of the thrill
Jeep® Grand Cherokee SRT8 reigns supreme with the auspicious title of “Fastest Vehicle in its Class.”(1) Specially bolstered race-inspired leather-faced seating holds you in place as you command a 420-hp 6.1L SRT™ HEMI® V8 engine with 420 lb-ft torque and an estimated top speed of over 240 km/h (150 mph). Only the beefed-up SRT 4WD system with its active full-time transfer case and all-speed traction control has the guts to handle this kind of action. SRT8’s incredible swiftness is perfectly countered by its four-piston Brembo® Performance brake calipers and 14.2-inch front and 13.8-inch rear rotors – more race-proven engineering that brings the good times to a sure-footed halt at your command.
